2022 Jeep Grand Cherokee Traffic Sign Assist System User Guide
TRAFFIC SIGN ASSIST SYSTEM
The Traffic Sign Assist (TSA) system uses a camera mounted on the windshield, as well as map data when the vehicle is equipped with Navigation, to detect recognizable road signs such as:
- Speed limits
- School zones
- No passing zones
NOTE:
- The TSA system will automatically display the detected road sign using the unit of measurement (mph or km/h) selected within the instrument cluster display.
- If no speed limit signs are detected, the system will revert to the speed limit signs that are stored in the Navigation system.
- The system always checks the traffic signs indicating the current speed limit. The system is able to recognize and display up to two different road signs in the instrument cluster display. These road signs can be found on the Driver Assist page.
ACTIVATION/DEACTIVATION
The TSA System can be enabled/disabled within the Uconnect system through the Safety/Driver Assistance menu. System ON is signaled by road signs shown on the instrument cluster display.
NOTE:
Even if the system is OFF, the speed limit sign will be displayed when the driver selects it on the HOME screen.
TRAFFIC SIGN ASSIST MODES
TSA has three selectable modes of operation that are available through the Uconnect system page 204.
Visual
When Visual is selected, the system will alert the driver when the current speed of the vehicle exceeds the detected speed limit by showing a graphic in the instrument cluster display.
Visual + Chime
When Visual + Chime is selected, the system will alert the driver when the current speed of the vehicle exceeds the detected speed limit by showing a graphic in the instrument cluster display, and by sounding an audible alert. The audible alert will last for 10 seconds, and the visual alert will remain on as long as the vehicle is exceeding the speed limit.
TSA Off
When the TSA system is turned off, the system will not show any traffic signs (unless selected in the HOME screen, which will show detected speed limit signs), and no alerts will be issued to the driver.
INDICATIONS ON THE DISPLAY
Detected traffic signs are shown in the instrument cluster display, and can display any combination of signs at one time (e.g. speed limit, speed limit and supplemental info, and “Do Not Pass” signs) depending on what information is available.
When a newly detected speed limit is higher than the current speed limit, the display will update along with an “up” arrow.
When a newly detected speed limit is lower than the current speed limit, the display will update along with a “down” arrow.
NOTE:
Up or down arrows will be displayed for up to five seconds.
- Current Speed Limit With Supplemental Information (School Zone)
- Next Speed Limit Detected
- No Passing Zone Detected
Supplemental Information
Supplemental information may be displayed along with a newly detected speed limit indicating special circumstances the driver should be aware of. Available supplemental information includes:
- School
- Construction
- Rain
- Snow
- Fog
NOTE:
Supplemental information will not be displayed when the vehicle is ONLY equipped with GPS.
Speed Limit Exceeded
When the vehicle’s speed exceeds the displayed speed limit by 3 mph (5 km/h), the speed limit sign on the instrument cluster display will show a red outline to alert the driver.
CAUTION!
- Traffic Sign Assist is designed to assist the driver and not to substitute the driver. It is the driver’s responsibility to continue to monitor the vehicle speed.
- Functionality may be limited or the system may not work if the sensor is obstructed.
- The system may have limited operation or not work at all in weather conditions such as heavy rain, hail, and thick fog. Strong light contrasts can influence the recognition capability of the sensor.
- The area surrounding the sensor must not be covered with stickers or any other object.
- Do not tamper or perform any operations in the area of the windshield glass directly surrounding the sensor.
- Clean foreign matters such as bird droppings, insects, snow or ice on the windshield. Use specific detergents and clean cloths to avoid scratching the windshield.
ACTIVE DRIVING ASSIST SYSTEM
OPERATION
The Active Driving Assist (ADA) system is combined with the Adaptive Cruise Control (ACC) system, and centers the vehicle in the driving lane while traveling at speeds up to 90 mph (145 km/h).
For ACC system operating instructions and system limitations, see Ú page 145.
NOTE:
- The driver should always obey traffic laws and speed limits. Never drive above applicable speed limit restrictions.
- The driver can override ADA at any time by braking, accelerating, or steering the vehicle.
Just like ACC, ADA will maintain a set speed as long as the set distance between your vehicle and the vehicle in front is maintained. ADA will also keep your vehicle centered between the lane lines, and monitor for other vehicles in adjacent lanes by utilizing the Blind Spot Monitoring sensors.
Two types of Active Driving Assist systems are available:
- Base ADA system
- Hands-Free ADA system
Base Active Driving Assist System — If Equipped
The Base ADA system uses sensors within the steering wheel to measure driver attentiveness and requires that the driver have their hands on the steering wheel at all times.
The system will generally aim to keep the vehicle centered in the lane, but when the driver turns the steering wheel (e.g. to move further away from a large vehicle in the next lane) the system will reduce its control and enter “co-steering” mode. While in co-steering mode, the system will provide reduced assistance and allow the driver to control the path of the vehicle. Once the driver stops providing input to the steering wheel, the system will require a few seconds to fully resume lane-centering assistance, especially during curves.
Hands-Free Active Driving Assist System —If Equipped
The Hands-Free ADA system uses sensors within the steering wheel and a driver monitoring camera located on top of the steering column to monitor driver attentiveness. The Hands-Free ADA allows the driver to remove their hands from the steering wheel, but requires that the driver continue to pay attention to the road.
NOTE
The camera may record images of the driver during certain crash, or near crash situations. To retrieve the images recorded by the camera, special equipment is required and access to the vehicle or the camera is needed.
Hands-Free ADA will also change lanes when a turn signal is activated if the lane in the direction indicated is valid and clear, noted by a dashed line in the direction of the available lane change. The system uses sensors, including Blind Spot Monitoring (BSM) sensors, to determine if a lane change is possible. If the assisted lane change is in progress, a green indication will appear.
WARNING!
The driver is always responsible for determining if a lane change is safe. Failure to follow this warning can result in a collision and death or serious personal injury.
NOTE:
- The Hands-Free Active Driving Assist system is only available on approved roadways. Please consult the Jeep® website for further details on supported roadways.
- The Hands-Free Active Driving Assist system requires an active subscription through Jeep® Connect (Uconnect Connected Services) package. If the ADA on/off button is pushed without an active subscription, the instrument cluster display will show the message “Active Driving Assist Unavailable Update Subscription”. Refer to the Uconnect Owner’s Manual Supplement for further information.
- If previously disabled, activating the Hands-Free Active Driving Assist system will also activate the Forward Collision Warning and Pedestrian Emergency Braking systems Ú page 261.
- If the vehicle is equipped with the Jeep® Connect (Uconnect Connected Services) package, additional data may be collected through the Jeep® Connect (Uconnect Connected Services) system. This includes information about the vehicle’s operation, a collision involving the vehicle, the use of the vehicle and its features, and in certain situations, the location and approximate GPS speed of the vehicle. Refer to the Uconnect Owner’s Manual Supplement for Terms and Conditions and Privacy Statements.
- Vehicle data may be read from the Hands-Free ADA system with special equipment and access to the vehicle or the Event Data Recorder (EDR).
WARNING!
The Active Driving Assist (ADA) system is a convenience system. It is not a substitute for active driver involvement. It is always the driver’s responsibility to be attentive of road traffic, weather conditions, vehicle speed, distance to the vehicle ahead, position in the lane compared to other vehicles, and brake operation to ensure safe operation of the vehicle under all road conditions. Your complete attention is always required while driving to maintain safe control of your vehicle. Failure to follow these warnings can result in a collision and death or serious personal injury.
Some states and local laws may require hands to be kept on the steering wheel at all times. For vehicles equipped with the Hands-Free ADA system, ONLY remove your hands from the steering wheel if the Hands-Free system is engaged, it is safe to do so, and it is permitted by state and local laws.
You should turn off the Active Driving Assist systems:
- When driving in complex driving situations (e.g. urban environments, construction zones, etc.), adverse weather (e.g. rain, snow, fog, sleet, dust), or adverse road conditions (e.g. heavy traffic, worn or missing lane markings, etc.).
- When entering a highway off-ramp.
- When driving on roads that are icy, snow-covered, or slippery.
- When circumstances do not allow safe driving.
