Vehicle Care What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 10‑7. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir. Notice: . 9-27 Battery Refer to the replacement number on the original battery label when a new battery is needed. { WARNING With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid. . Using the wrong fluid can badly damage brake hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic system can damage brake hydraulic system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid. If brake fluid is spilled on the vehicle's painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on the vehicle. If you do, wash it off immediately. { DANGER Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. If the battery has a very low charge or is dead, it might not be possible to remove the ignition key from the ignition switch or shift out of P (Park). See Shifting Out of Park on page 8‑25.
