Brake Fluid

The brake fluid master cylinder reservoir is located under the hood on the driver’s side of the vehicle. Check the brake fluid level before each use of the vehicle. Maintain the fluid level between the MIN and MAX lines on the reservoir.

If the BRAKE FAILURE indicator illuminates, brake fluid may be low. Check the brake fluid level.
Use DOT 4 brake fluid in the brake fluid reservoir. Use fluid only from a sealed, clean container.

Brake Fluid Precautions

WARNING
Using the wrong fluid or allowing air or contaminants into the fluid system can damage the system seals or result in a malfunction that could lead to serious injury or death. Use only DOT 4 brake fluid from a sealed container.
Do not operate the front brake with the reservoir cover removed. Fluid could overflow from the reservoir and allow air to enter the system. Air in the brake system could cause the brakes to malfunction.
An over-full reservoir may cause brake drag or brake lock-up, which could result in serious injury or death. Maintain brake fluid at the recommended level. Do not overfill.
After opening a bottle of brake fluid, always discard any unused portion. Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it rapidly absorbs moisture from the air. The moisture causes the boiling temperature of the brake fluid to drop, which can lead to early brake fade and the possibility of accident or serious injury
NOTICE
Brake fluid will damage painted surfaces and plastic parts. Always clean spilled brake fluid immediately with water and a mild detergent.

Brake Fluid Change

Change the brake fluid every two years or 10,000 miles (16,093 kilometers), whichever comes first. Always change fluid if the fluid becomes contaminated, if the fluid condition is questionable, or if the type and brand of the fluid in the reservoir are unknown. See your authorized dealer or another qualified person for this service.

Brake Fluid Level

Check the brake fluid level before each use of the vehicle.

  1. Position the vehicle on a level surface.
  2. On models equipped with a manual transmission vehicles, place the transmission in gear. On models equipped with AutoDrive vehicles, set the parking brake.
  3. Open the hood.
  4. Wipe the fluid container and the area around the reservoir cover with a clean cloth.
  5. View the fluid level in the reservoir. If the fluid level is below the MIN line on the reservoir, remove the cap and add the recommended fluid to the MAX line. Do not overfill.
  6. Reinstall the reservoir cap.
  7. Depress the brake pedal forcefully for a few seconds. Check for fluid leakage around the master cylinder fittings and the brake caliper fittings.
