Braking Systems

The braking system is the most important safety system in a vehicle and helps bring the vehicle to a complete stop.

Warning: It is critical to occupant safety that your braking systems are always functioning properly. Contact a Lucid Service Center immediately if you experience any braking issues or receive any fault messages regarding the braking system.

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 brakes because it can cause premature brake wear.

CAUTION: In extreme conditions, ice, mud, or other debris can build up on the inside of the wheel rims, scraping the brake calipers and damaging the finish. Remove any excess debris before driving.

The foot pedal operates the friction brakes through an electronic brake booster. If the vehicle loses power when driving, you may experience changes to the brake pedal feel, but continue to use the brake pedal to slow the vehicle. In rare cases, a vehicle power loss can require increased effort to the brake pedal to slow the vehicle.

A system check is performed when the vehicle is started, included a brake check function test. If brake-related faults are found, the corresponding warning indicators will remain illuminated.

The Red Brake Indicator and a notification message will display on the Clearview Cockpit if there is a significant brake system fault or the brake fluid level in the reservoir is low. Contact a Lucid Service Center as soon as possible.

Note: New brakes may produce increased noise during a break-in period, during which the brake pad and rotor optimize their surface contact area and friction force. A typical break-in period is approximately 25-55 stops using the friction brakes from 35 mph (56 km/h) or higher.

Anti-Lock Braking System (ABS)

Your vehicle is equipped with an Anti-lock Braking System (ABS) that helps prevent the wheels from locking during hard braking or braking on roads with reduced grip.

Warning: Always maintain an appropriate distance from the vehicle in front because ABS cannot overcome the physical limitations of trying to stop the vehicle a very short 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.

The ABS monitors the slip ratio of each wheel during braking and modulates the brake fluid pressure at each wheel to prevent the wheels from locking. This system helps maintain stability and steerability during braking events.

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

These conditions demonstrate that ABS is operating and are not a cause for concern.

Emergency Braking

Warning: Do not pump the brake pedal in an emergency.

In an emergency, fully press the brake pedal, even when the road surface is slippery. Maintain firm and steady pressure on the brake pedal through ABS pulsations.

Secondary Collision Mitigation System

The secondary collision mitigation system, or post-collision braking system, automatically triggers the vehicle brakes if the vehicle detects a crash. The system is designed to activate the electric park brake automatically after the vehicle comes to a standstill.

The driver can override the secondary collision mitigation braking by either fully depressing the accelerator or brake pedal.

ABS Warning Indicator

The ABS indicator displays with a notification message on the Clearview Cockpit. If illuminated, the ABS is not operational. Contact a Lucid Service Center as soon as possible to have the fault repaired.

CAUTION: The pedal-operated braking system remains operational even when ABS is disabled. Be aware that braking distances may increase and wheels may lock.

Regenerative Braking

Regenerative braking slows the vehicle and feeds energy back to the high-voltage battery whenever the vehicle is decelerating without the use of the brake pedal.

Warning: High regenerative braking can cause an increase in frequency of traction control interventions when driving the vehicle in snowy/icy conditions. Lucid recommends switching to Standard level when driving in such conditions to avoid excessive traction control interventions.

Although you may need to use the brake pedal to stop in certain situations, you can take advantage of regenerative braking by anticipating your stops and reducing accelerator pedal position.

Note: The brake lights turn on to alert others that you are slowing down if regenerative braking is adequately slowing your vehicle (such as, when your foot is completely off the accelerator pedal at highway speeds). These lights flash in hard braking scenarios for emergency stops.

During regenerative braking, the charge/power meter horizon line that sits below 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 may 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 too hot or cold or if the battery is already charged to its maximum allowable level.

Note: You'll notice a difference in driving behavior if the regenerative braking levels become limited. In that case, you may need to apply the brake pedal more frequently in such conditions.

Regenerative Braking Settings

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

Standard - Provides the standard amount of regenerative braking.

The vehicle takes longer to slow down and coasts further than if set to High when you release the accelerator.
High - Provides the maximum amount of regenerative braking.
The vehicle decelerates faster and reduces the need to use the brakes when you release the accelerator.

When the Standard or High level of regenerative braking is selected, your Lucid Gravity will retain the setting when the vehicle is power cycled.

Stop Modes

The HOLD and ROLL Stop Modes are designed to 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 will hold until the driver presses the accelerator pedal again.

If it is set to ROLL, the car will not remain stationary without continued manual application of the brake pedal.

Note: When the vehicle is stopped on a slope that may cause rolling backward while in D (Drive) or rolling forward while in R (Reverse), the Automatic Vehicle Hold feature will hold the vehicle without continued manual application of the brake pedal until the driver presses the accelerator again or changes gear and presses the brake pedal again.

Note:

The Hold indicator is displayed on the Clearview Cockpit when Automatic Vehicle Hold is engaged or once HOLD mode has engaged the brakes.

To configure, use the Pilot Panel and touch > Vehicle > Drive Settings, then select the desired mode.

Note: Brake settings, (HOLD/ROLL), can only be changed when the vehicle is in P (Park), and will save to your user profile.

Note: Vehicle hold disengages if the driver shifts into N (Neutral), or presses and releases the brake pedal.

Note: Vehicle Hold will disengage and shift into P (Park) in any of the following instances:

The hold has been braking for approximately 10 minutes.
The system detects that the driver has exited the vehicle.

Parking Brake

The parking brake operates on the rear wheels, independent of the pedal-operated brake system.

CAUTION: You will not be able to shift out of Park in the unlikely event that your vehicle loses electrical power, and therefore, will be unable to release the parking brake. Contact a Lucid Service Center for assistance.

The parking brake automatically applies when P (Park) is selected, and releases when any other gear is selected. It is also engaged by certain systems when a time limit is reached. See Stop Modes.

The Red Parking Brake Indicator is displayed on the Clearview Cockpit when the parking brake is engaged. A flashing indicator signals either the parking brake could be trying to actuate with a fault present or the parking brake is stuck in operation.

Emergency Use

Pressing and holding the P (Park) button decelerates the vehicle to a low speed using the service brakes, then applies the parking brake once the vehicle has stopped.

Parking on a Slope

Warning: You are responsible for parking safely. Parking with a trailer or in adverse conditions may reduce the parking hold of the vehicle 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: The vehicle may give audible and visual warnings if the grade detected is too steep for the parking brake to guarantee secure hold of the vehicle. Drive to a less steep area and re-park.

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

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 the end of life. Contact an authorized Lucid Service Center to replace the brake pads.

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 Red Brake Wear Indicator will display on the Clearview Cockpit if the system has detected that the brake pads are near or at the end of their usable life. Contact a Lucid Service Center as soon as possible to have the brakes inspected.
