2023 Cadillac LYRIQ Airbag System
The vehicle has the following airbags:
- A frontal airbag for the driver
- A frontal airbag for the front outboard passenger
- A knee airbag for the driver.A knee airbag for the front outboard passenger.
- A seat-mounted side-impact airbag for the driver
- A seat-mounted side impact airbag for the front outboard passenger
- A roof-rail airbag for the driver and the passenger seated directly behind the driver
- A roof-rail airbag for the front outboard passenger and the passenger seated directly behind the front outboard passenger
All vehicle airbags have the word AIRBAG on the trim or on a label near the deployment opening. For frontal airbags, the word AIRBAG is on the center of the steering wheel for the driver and on the instrument panel for the front outboardpassenger. For knee airbags, the word AIRBAG is on the lower part of the instrument panel. For seat-mounted side-impact airbags, the word AIRBAG ison the side of the seatback orside of the seat closest to the door. For roof-rail airbags, the word airbag is on the ceiling or trim. Airbags are designed to supplement the protection provided by seat belts. Even though today’s airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job. Here are the most important things to know about the airbag system:
WARNING: You can be severely injured or killed in a crash if you are not wearing your seat belt, even with airbags. Airbagsare designed to work with seat belts, not replace them. Also, airbags are not designed to inflate in every crash. In some crashes seatbelts are the only restraint. See When Should an Airbag Inflate? 63. Wearing your seat belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are“supplemental restraints” to the seat belts. Everyone in the vehicle should wear a seat belt properly, whether or not there is an airbag for that person.
WARNING: Because airbags inflate with great force and faster than the blink of an eye, anyone who is up against, or very close to, any airbag when it inflates can be seriously injured or killed. Do not sit unnecessarily close to any airbag, as you would be if sitting on the edge of the seat or leaning forward. Seat belts help keep you in position before and during a crash. Always wear a seat belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. The seat belts and the front outboard passenger airbags are most effective when you are sitting well back and upright in the seat with both feet on the floor. Occupants should not lean on or sleep against the door or side windows in seating positions with seat-mounted side-impact airbags and/or roof-rail airbags.
WARNING: Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Always secure children properly in the vehicle. To read how see Older Children73 or
Infants and Young Children 75. 
There is an airbag readiness light on the instrument cluster, which shows the airbag symbol. The system checks the airbagelectrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light112.
Where Are the Airbags? 
The driver’s frontal airbag is in the center of the steering wheel. The front outboard passengerfrontal airbag is in the passenger side instrument panel. 
The driver’s knee airbag is below the steering column. The front outboard passenger knee airbag is below the glove box. 
Driver Side Shown, Passenger Side Similar
The driver and front outboard passenger seat-mounted side-impact airbags are on the side of the seatbacks closest to the door. 
Driver Side Shown, Passenger Side Similar
The roof-rail airbags for the driver, front outboard passenger, and second-row outboard passengers are in the ceiling above the side windows.
WARNING: If something is between an occupant and an airbag, the airbag might not inflate properly or it might force the object into that person causing severe injury or even death. The path of an inflating airbag must be kept clear. Do not put anything between an occupant and an airbag, and do not attach or put anything on the steering wheel hub or on or near any other airbag covering. Do not use seat accessories that block the inflation path of a seat-mounted side-impact airbag. Never secure anything to the roof of a vehicle with roof-rail airbags by routing a rope or tie‐down through any door or window opening.If you do, the path of an inflating roof-rail airbag will be blocked.
When Should an Airbag Inflate?
This vehicle is equipped with airbags. See Airbag System59. Airbags are designed to inflate if the impact exceeds the specific airbag system’s deployment threshold. Deployment thresholds are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants. The vehicle has electronic sensors that help the airbag system determine the severity of the impact. Deployment thresholds can vary with specific vehicle designs. Frontal airbags are designed to inflate in moderate to severe frontal crashes to help reduce the potential for severe injuries, mainly to the driver’s or front outboard passenger’s head and chest.
Whether the frontal airbags will or should inflate is not based primarily on how fast the vehicle is traveling. It depends on what is hit, the direction of the impact, and how quickly the vehicle slows down. Frontal airbags may inflate at different crash speeds depending on whether the vehicle hits an object straight on or at an angle, and whether the object is fixed or moving, rigid or deformable, narrow or wide. Frontal airbags are not intended to inflate during vehicle rollovers, in rear impacts, or in many side impacts. In addition, the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to crash severity.
Knee airbags are designed to inflate in moderate to severe frontal impacts. Knee airbags are not designed to inflate during vehicle rollovers, in rear impacts, or in many side impacts. Seat-mounted side impact airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. These airbags may also inflate in some moderate to severefrontal impacts. Seat-mounted side impact airbags are not designed to inflate in rollovers or rear impacts. A seat-mounted side impact airbag is designed to inflate on the side of the vehicle that is struck. Roof-rail airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. In addition, these roof-rail airbags may inflate during a rollover or in a severe frontal impact. Roof-rail airbags are not designed to inflate in rear impacts. Both roof-rail airbags may inflate when either side of the vehicle is struck or if the sensing system predicts that the vehicle is about to roll over onits sides, or in a severe frontal impact. In any particular crash, no one can say whether an airbag should have inflated simply because of the vehicle damage or repair costs.
What Makes an Airbag Inflate?
In a deployment event, the sensing system sends an electrical signal triggering the release of gas from the inflator. Gas from the inflator fills the airbag causing the bag to break out of the cover. The inflator, the airbag, and related hardware are all part of the airbag module. For airbag locations, see Where Are the Airbags?61.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. Airbags supplement the protection provided by seat belts by distributing the force of the impact more evenly over the occupant’s body. Rollover capable roof-rail airbags are designed to help contain the head and chest of occupants in the outboardseating positions in the first and second rows. The rollover capable roof-rail airbags are designed to help reduce the risk of full or partial ejection in rollover events, although no system can prevent all such ejections. But airbags would not help inmany types of collisions, primarily because the occupant’s motion is not toward those airbags. See When Should an Airbag Inflate? 63. Airbags should never be regarded as anything more than a supplement to seat belts.
What Will You See After an Airbag Inflates?
After frontal, knee, and seat-mounted side-impact airbags inflate, they quicklydeflate, so quickly that some people may not even realize the airbags inflated. Roof-rail airbags may still be at least partially inflated for some time after they inflate. Some components of the airbag module may be hot for several minutes. For the location of the airbags, see Where Are the Airbags?61. The parts of the airbag that come into contact with you may be warm, but not too hot to touch. There may be somesmoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it prevent people from leaving the vehicle.
WARNING: When an airbag inflates, there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates, then get fresh air by opening a window or a door. If you experience breathingproblems following a deployment, you should seekmedical attention.
The vehicle has a feature that may automatically unlock the doors, turn on the interior lamps, and hazard warning flashers after the airbags inflate. The feature may also activate, without airbag inflation, after an event thatexceeds a predetermined threshold. After turning the vehicle off and then on again, the doors can be locked, the interior lamps can be turned off, and the hazard warning flashers can be turned offusing the controls for those features. If any of these systems are damaged in the crash they may not operate as normal.
WARNING: A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle, such as the brake and steering systems, etc. Even if the vehicle appears to be drivable after a moderate crash, there may be concealed damage that could make it difficult to safely operate the vehicle. Use caution if attempting to restart the vehicle after a crash has occurred.
Plug-in vehicles have a high voltage battery and a standard 12-volt battery. If an airbag inflates or thevehicle has been in a crash, the sensing system may shut down the high voltage system. When this occurs, the high voltage battery is disconnected and the vehicle will not start. Before the vehicle can be operated again, it must be serviced at your dealer. In many crashes severe enough to inflate the airbag,windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the front outboard passenger airbag.
- Airbags are designed to inflate only once. After an airbag inflates, you will need some new parts for the airbag system. If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for the vehicle covers the need to replace other parts.
- The vehicle has a crash sensing and diagnostic module which records information after a crash. See Vehicle Data Recording and Privacy 397 and Event Data Recorders398.
- Let only qualified technicians work on the airbag system. Improper service can mean that an airbag system will not work properly. See your dealer for service.
Passenger Sensing System
The vehicle has a passenger sensing system for the front outboard passenger position. The passenger airbag status indicator will light on the overhead console when the vehicle is started. 
The words ON and OFF, and the symbols for on and off, will be visible during the system check. When the system check is complete, either the word ON or OFF and the symbol for on or off will be visible. See Passenger Airbag Status Indicator 113. The passenger sensing system turns off the front outboard passenger frontal airbag and knee airbag under certain conditions. No other airbag is affected by the passenger sensing system. The passenger sensing system works with sensors that are part of the front outboard passenger seat and seat belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the front outboard passenger frontal airbag and knee airbag should be allowed to inflate or not. According to accident statistics, children are safer when properly secured in a rear seat in the correct child restraint for their weight and size.Whenever possible, children aged 12 and under should be secured in a rear seating position. Never put a rear-facing child seat in the front. This is because the risk to the rear-facing child is so great if the airbag inflates.
WARNING: A child in a rear-facing child restraint can be seriously injured or killed if the passenger’s frontal airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the passenger frontal air bag inflates and the passenger seat is in a forward position. Even if the passenger sensing system has turned off the front outboard passenger airbag(s), no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though the airbag(s) are off. Never put a rear-facing child restraint in the front seat, even if the airbag is off. If securing a forward-facing child restraint in the front outboard passenger seat, always move the seat as far back as it will go. It is better to secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available.
The passenger sensing system is designed to turn off the front outboard passenger frontal airbag and knee airbag if:
- The front outboard passenger seat is unoccupied.
- The system determines an infant is present in a child restraint.
- A front outboard passenger takes his/her weight off of the seat for a period of time.
When the passenger sensing system has turned off the front outboard passenger frontal airbag and knee airbag, the OFF indicator will light and stay lit as a reminder that the airbags are off. See Passenger Airbag Status Indicator113. The passenger sensing system is designed to turn on the front outboard passenger frontal airbag and knee airbag, anytime the system senses that a person of adult size is sitting properly in the front outboard passenger seat. When the passenger sensing system has allowed the airbags to be enabled, the indicator will light and stay lit as a reminder that the airbags are active. For some children, including children in child restraints, and for very small adults, the passenger sensing system may or may not turn off the front outboard passengerfrontal airbag and knee airbag, depending upon the person’s seating posture and body build. Everyone in the vehicle who has outgrown child restraints should wear a seat belt properly—whether or not there is an airbag for that person.
WARNING: If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbagsystem. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light112 for more information, including important safety information.
If the On Indicator Is Lit for a Child Restraint
The passenger sensing system is designed to turn off the front outboard passenger frontal airbag and knee airbag if the system determines that an infant is present in a child restraint. If a child restraint has been installed and the ON indicator is lit:
- Turn the vehicle off.
- Remove the child restraint from the vehicle.
- Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters, or seat massagers.
- Reinstall the child restraint following the directions provided by the child restraint manufacturer and refer to Securing Child Restraints (With the SeatBelt in the Front Seat)90 or Securing Child Restraints (With the Seat Belt in the Rear Seat)88.
Make sure the seat belt retractor is locked by pulling the shoulder belt all the way out of the retractor when installing the child restraint, even if the child restraint is equipped with a seat belt lock off. When the retractor lock is set, the belt can be tightened but not pulled out of the retractor. - If, after reinstalling the child restraint and restarting the vehicle, the ON indicator is still lit, turn the vehicle off. Then slightly recline the vehicle seatback and adjust the seat cushion, if adjustable, to make sure that the vehicle seatback is not pushing the child restraint into the seat cushion. Also, make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint. See Head Restraints38.
- Restart the vehicle. The passenger sensing system may or may not turn off the airbags for a child in a child restraint depending upon the child’s size. It is better to secure the child restraint in arear seat. Never put a rear-facing child restraint in the front seat, even if the ON indicator is not lit.
If the Off Indicator Is Lit for an Adult-Sized Occupant 
If a person of adult size is sitting in the front outboard passenger seat, but the OFF indicator is lit, it could be because that person is not sitting properly in the seat or that the child restraint locking feature is engaged. Use the following steps to allow the system to detect that person and enable the front outboardpassenger frontal airbag and knee airbag:
- Turn the vehicle off.
- Remove any additional material from the seat, suchas blankets, cushions, seat covers, seat heaters, or seat massagers.
- Place the seatback in the fully upright position.
- Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended.
- If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag off for some adult-sized occupants. If this happens, unbuckle the belt, let the belt go back all the way, and then buckle the belt again without pulling the belt out all the way.
- Restart the vehicle and have the person remain in this position for two to three minutes after the ON indicator is lit.
WARNING: If the front outboard passenger airbag is turned off for an adult-sized occupant, the airbag will not be able to inflate and help protect that person in a crash, resulting in an increased risk of serious injury or even death. An adult-sized occupant should not ride in the frontoutboard passenger seat if the passenger airbag OFF indicator is lit.
Additional Factors Affecting System Operation
Seat belts help keep the passenger in position on the seat during vehicle maneuvers and braking, which helps the passenger sensing system maintain the passenger airbag status. See “Seat Belts” and“Child Restraints” in the Index for additional information about the importance of proper restraint use. A thick layer of additionalmaterial, such as a blanket or cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment except when approved by GM for your specific vehicle. See Adding Equipment to the Airbag-Equipped Vehicle71 for more information about modifications that can affect how the system operates. The ON indicator may be lit if an object, such as a briefcase, handbag, grocery bag, laptop, or another electronic device, is put on an unoccupied seat. If this is not desired, remove the object from the seat.
WARNING: Stowing articles under the passenger seat or between the passenger seat cushion and seatback may interfere with the proper operation of the passenger sensing system.
Servicing the Airbag-Equipped Vehicle
Airbags affect how the vehicle should be serviced. There are parts of the airbag system in several places around the vehicle. Your dealer and the service manual have information about servicingthe vehicle and the airbag system. To purchase a service manual, see Publication Ordering Information394.
WARNING: For up to 10 seconds after the vehicle is turned off and the battery is disconnected, an airbag can still inflate during improper service. You can be injured if you are close to an airbag when it inflates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.
Adding Equipment to the Airbag-Equipped Vehicle
Adding accessories that change the vehicle’s frame, bumper system, height, front end, or side sheet metal may keep the airbag system from working properly. The operation of the airbag system can also be affected by changing, including improperly repairing or replacing, any parts of the following:
- Airbag system, including airbag modules, front or side impact sensors, sensing, and diagnostic module, or airbag wiring
- Front seats, including stitching, seams, or zippers
- Seat belts
- Steering wheel, instrument panel, an overhead console, ceiling trim, or pillar garnish trim
- Inner door seals, including speakers
Your dealer and the service manual have information about the location of the airbag modules and sensors, sensing and diagnostic module, and airbag wiring along with the proper replacement procedures.
In addition, the vehicle has a passenger sensing system for the front outboard passenger position, which includes sensors that are part of the passenger seat. The passenger sensing system may not operate properly if the original seat trim is replaced with non-GM covers, upholstery, or trim; or with GM covers, upholstery, or trim designed for a different vehicle. Any object, such as an aftermarket seat heater or a comfort-enhancing pad or device, installed under or on top of the seat fabric, could also interfere with the operation of the passenger sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent the passenger sensing system from properly turning off the passenger airbag(s). See Passenger Sensing System66.
If the vehicle has rollover roof-rail airbags, see Different Size Tires and Wheels352 for additional important information. If the vehicle must be modified because you have a disability and have questions about whether the modifications will affect the vehicle’s airbag system, or if you have questions about whether the airbag system will be affected if the vehicle is modified forany other reason, call Customer Assistance. See Customer Assistance Offices386.
Airbag System Check
The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working. See Airbag Readiness Light112.
CAUTION: If an airbag covering is damaged, opened, or broken, the airbag may not work properly. Do not open or break the airbag coverings. If there are any opened or broken airbag coverings, have the airbag covering and/or airbag module replaced. For the location of the airbags, see Where Are the Airbags?61. See your dealer for service.
Replacing Airbag System Parts after a Crash
WARNING: A crash can damage the airbag systems in the vehicle. A damaged airbag system may not properly protect you and your passenger(s) in a crash, resulting in serious injury oreven death. To help make sure the airbag systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.
If an airbag inflates, you will need to replace airbag system parts. See your dealer for service. If the airbag readiness light stays on after the vehicle is started or comes on when you are driving, the airbag system may not work properly. Have the vehicle serviced right away. See Airbag Readiness Light112.
