Checking Windshield Washer Fluid


Checking Brake Fluid

Low Brake Fluid Warning Indicator

If the fluid in the brake reservoir drops below the recommended level, the brake warning icon will be displayed on the Glass Cockpit. This will be accompanied by a notification message.

Warning: If the low brake fluid notification displays while driving, stop as soon as safety permits by gently applying the brakes. Do not continue driving. Immediately contact a Lucid Service Center.

Checking the Fluid Level

Check the brake fluid level with the vehicle on level ground.

  1. Remove the under hood rear apron.
  2. Remove the brake reservoir cover.


  3. Check the fluid level visually by looking at the outside marks on the side of the reservoir without removing the filler cap.


    The brake fluid level should always be between the MIN and the MAX marks.

    Note: Although the brake fluid level slightly drops during normal use as a result of brake pad wear, it should not drop below the MIN mark. Excessive or frequent fluid loss may indicate a leak in the system.

Topping Off Brake Fluid

Warning: Only use new fluid from a sealed, air-tight container. Never use previously used fluid or fluid from a previously opened container. Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency.
Warning: Brake fluid is highly toxic. Keep containers sealed and out of the reach of children. If accidental consumption of brake fluid is suspected, seek immediate medical attention.
Warning: Do not allow brake fluid to come into contact with your eyes. If this happens, flush your eyes with clean water for at least 15 minutes and seek immediate medical attention.

To top off the fluid:

  1. Clean the filler cap before removing it to prevent dirt from entering the reservoir.
  2. Unscrew the cap and remove.
  3. Fill the reservoir to between the MIN and the MAX marks using a clean funnel and brake fluid meeting specification DOT4.
  4. Install the reservoir cap.
CAUTION: Brake fluid will damage painted surfaces. Immediately soak up any spills with an absorbent cloth and wash the affected area with a mixture of car shampoo and water.

Replacing Brake Fluid

The brake fluid should be replaced every 2 years or every 24,000 miles, whichever comes sooner.

Checking Windshield Washer Fluid

Check the level of the windshield washer fluid monthly, or more frequently if you use it often.

An indicator will display on the Glass Cockpit if the quantity of fluid remaining in the washer reservoir drops below the recommended level. This is accompanied by a notification message.

Periodically operate the washers to ensure that the nozzles are clear and properly directed. See Cleaning Washer Jets if a washer jet performs poorly.

Topping Off Windshield Washer Fluid

Warning: In temperatures below 39 °F (4 °C), use a washer fluid with deicer. In cold weather, using a washer fluid without deicer can cause the fluid to freeze on contact with the windshield, impairing visibility.
Note: Some national or local regulations restrict the use of Volatile Organic Compounds (VOCs). VOCs are commonly used as antifreeze in washer fluid. Use a washer fluid with limited VOC content only if it provides adequate freeze resistance in all the climates where you drive.


  1. Clean the filler cap before opening it to prevent dirt from entering the reservoir.
  2. Open the filler cap.
  3. Fill the reservoir until the fluid is visible just below the filler neck.
  4. Close the filler cap.
CAUTION: Washer fluid can damage painted surfaces. Immediately wipe up any spills with an absorbent cloth and wash the affected area with water.
