Maintenance and service Power steering fluid WARNING Never let power steering fluid contact your eyes because power steering fluid can be harmful to your eyes. If power steering fluid gets in your eyes, immediately flush them thoroughly with clean water. For safety, when performing this work, wearing eye protection is advisable. The power steering fluid expands largely as its temperature rises; the fluid level differs according to fluid temperature. Therefore, the dipstick has two different checking ranges for hot and cold fluids on it. J Checking the fluid level when the fluid is hot WARNING Be careful not to burn yourself because the fluid may be hot. D When power steering fluid is being added, use only clean fluid, and be careful not to allow any dirt into the tank. And never use different brands together. D Avoid spilling fluid when adding it in the tank. Check the power steering fluid level monthly. 1. Drive the vehicle several miles to raise the temperature of the power steering fluid up to normal operating temperature, about 140°F (60°C). 2. Park the vehicle on a level surface, and stop the engine. 3. Turn the reservoir cap counterclockwise to remove the fluid level dipstick, wipe the dipstick clean, and reinsert it.
