Notes

  • The recommended brake fluid type is also listed in your owner's manual. 
  • The recommended brake fluid type is also noted on the top of the cap for the brake fluid reservoir.
  • Do not allow the brake fluid to spill on the paint of the vehicle. If brake fluid gets on the paint, wash it off with water. Brake fluid can damage the paint. 
  • Note that a brake light staying on at startup can indicate a problem with the brake system, but it can be an issue with the charging system or battery in some cases.
  • You should not lose brake fluid regularly. If you are losing brake fluid, have the brake system checked by a mechanic immediately. 
  • If your brake warning light (or ABS light) comes on or is flashing while driving or at startup, stop and check the brake fluid level.
  • Driving with the brake light on can put you, your passenger, and others at risk.
