2022 Lucid Air Brakes Owners Manual

2022 Lucid Air Brakes

Braking Systems

• WARNING: It is critical to occupant safety that your braking systems are always functioning properly. If you experience any braking issues or receive any fault messages regarding the braking system, contact a Lucid Service Center immediately.
• WARNING: Driving through heavy rain or water can have a temporary adverse effect on braking efficiency.
• CAUTION: Do not rest your foot on the brake pedal while the vehicle is in motion unless you are applying the brake pedal. Resting your foot on the brake pedal can cause premature break wear.

The foot pedal hydraulically-operated brakes are electrically boosted, but only when the vehicle is On. If the vehicle loses power when driving, you will need to apply more force on the brake pedal and you will experience longer stopping distances.

If the brake fluid level in the reservoir is low, a red brake indicator and a notification message will be displayed on the Cockpit Panel. See Checking Brake Fluid.
If the yellow brake indicator displays on the Cockpit Panel, a brake system fault has been detected. Contact a lucid Service Center as soon as possible to have the brakes inspected.

Anti-Lock Braking System (ABS)

• WARNING: Always maintain an appropriate distance from the vehicle in front. ABS cannot overcome the physical limitations of trying to stop the vehicle in too short a distance.
• WARNING: The braking distance on road surfaces that are wet, slippery or loose is always increased; even for vehicles equipped with ABS.
• WARNING: Always drive with due care and attention to your surroundings and road conditions. ABS will not correct driver errors.

Your vehicle is equipped with an Anti-lock Braking System (ABS) that helps prevent the wheels from locking during hard braking or when braking on roads with reduced grip.
During braking, the ABS monitors the speed of each wheel and varies the brake fluid pressure at each wheel to prevent the wheels from locking. This system helps maintain steering ability during maximum brake application.

When ABS activates, you may experience the following conditions:

• Pulsations in the brake pedal
• A slight drop of the brake pedal
• Clicking or grinding noises
• ABS warning indicator flickering on and off as the system activates

These conditions demonstrate that ABS is operating and are not a cause for concern. Maintain a firm and steady pressure on the brake pedal while experiencing the pulsation.

Emergency braking
WARNING: Do not pump the brake pedal. This interrupts the operation of the ABS system and increases your stopping distance, which could lead to a collision.
In an emergency, fully press the brake pedal even when the road surface is slippery.

ABS warning indicator

The ABS indicator displays on the Cockpit Panel, along with a notification message.

• If the indicator is flashing, a fault has been detected.
• If the indicator remains displayed, the system has been disabled.

Contact a Lucid Service Center as soon as possible to have the fault repaired.

CAUTION: The pedal-operated braking system remains operational even when the ABS warning indicator illuminates. Be aware that braking distances may increase and wheels may lock under heavy braking.

Regenerative Braking

WARNING: If driving the vehicle in reduced-traction conditions (that is, icy or snowy conditions), the use of High regenerative braking level may cause traction control to operate more frequently. Lucid recommends switching to Standard level when driving in such conditions.
Whenever the vehicle is moving and your foot is off the accelerator, regenerative braking slows the vehicle and feeds energy back to the high-voltage battery.
While you should still use the brake pedal whenever needed to stop safely, you can take advantage of regenerative braking by anticipating your stops and reducing the accelerator pedal position.

NOTE: If regenerative braking is aggressively slowing your vehicle (such as when your foot is completely off the accelerator pedal at highway speeds), the brake lights turn on to alert others that you are slowing down.

During regenerative braking, the charge/power meter that arcs over the speedometer shows the current amount of energy being generated and fed back to the high-voltage battery. The amount of generated energy being fed back to the high-voltage battery can vary depending on the current state of the battery and the regenerative braking setting being used. For example, regenerative braking may be limited if the battery is extremely hot or cold or if the battery is already charged to its maximum allowable level.

Regenerative braking settings

On the Pilot Panel, press > Vehicle> Drive Settings, then press to select between two levels of Regenerative Braking

• Standard – Provides the standard amount of regenerative braking. When you release the accelerator, the vehicle takes longer to slow down and coasts further than if set to High.
• High– Provides the maximum amount of regenerative braking. When you release the accelerator, the vehicle slows down faster, reducing the need to use the brakes.

NOTE: Should regenerative braking levels be limited, you’ll notice a difference in driving behavior. You may need to apply the brake pedal more frequently in these conditions.

Stop Mode

Stop mode controls brake settings, and can keep your vehicle stopped even when your foot is not on the brake pedal.
When set to HOLD, the vehicle remains stationary after a stop. The brakes hold until the driver presses the accelerator pedal again. If set to ROLL, the car rolls freely after releasing the accelerator.
To configure, use the Pilot Panel and touch > Vehicle> Drive Settings, then select the desired mode.
NOTE: The default setting is HOLD, and can only be changed when the vehicle is in P (Park). The setting saves to your User Profile.
NOTE: Stop Mode disengages if the driver shifts into N (Neutral) or presses and releases the brake pedal.
NOTE: Stop Mode will disengage and shift into P (Park) in any of the following instances:

• Stop Mode has been actively braking for approximately 10 minutes.
• The system detects that the driver has exited the vehicle.

Parking Brake

CAUTION: In the unlikely event that your vehicle loses electrical power, you will not be able to select another gear and therefore will be unable to release the parking brake. Contact a Lucid Service Center for assistance.
The parking brake operates on the rear wheels only, and is independently controlled of the pedal-operated brake system.

The parking brake automatically applies when P (Park) is selected, and releases when any other gear is selected.
It may also be engaged by certain systems when a set time limit is reached, such as Stopping Mode. See Stop Mode.
The red parking brake indicator is displayed on the Cockpit Panel whenever the parking brake is engaged or when the parking brake has not completed its operation properly.

If the indicator is amber, a fault has been detected and the parking brake may not be applied when the vehicle is in P (Park). This will be accompanied by a notification on the Cockpit Panel. Contact a Lucid Service Center to have the fault repaired.

Emergency use

CAUTION: Driving the vehicle with the parking brake applied, or repeated use of the parking brake to slow the vehicle, may cause serious damage to the brake system.
In an emergency, pressing and holding the P (Park) button decelerates the vehicle to a low speed using the service brakes, then applies the parking brake.

Parking on a slope

• WARNING: In snowy or icy conditions, the rear wheels may not have sufficient traction to prevent the vehicle from sliding when parked on a slope. You are always responsible for parking safely.
• WARNING: If parking on too steep a grade for the parking brake to securely hold the vehicle, the vehicle will give audible and visual warnings. Drive to a less steep area and re-park.

As an added precaution:

• If your vehicle is parked on a hill and facing uphill, turn the steering wheel so the front wheels are pointing away from the curb.
• If your vehicle is parked on a hill and facing downhill, turn the steering wheel so the front wheels are pointing towards the curb.

Brake Pad Wear

WARNING: Neglecting to replace worn brake pads can damage the brake rotors, reduce the vehicle’s braking efficiency, and increase the distance needed to stop the car.
The brake pads installed on your vehicle are equipped with wear indicators, which will cause the vehicle to display warning messages when the brake pads are nearing end of life. To replace the brake pads, contact the authorized Lucid Motors Service Center.

If the red brake wear indicator displays on the Cockpit Panel, the system has detected excessive brake wear. Contact a Lucid Service Center as soon as possible to have the brakes inspected.
