Checking power steering fluid c. Reinstall the filler cap. d. Remove the filler cap again and look at the fluid level. If the fluid is cold, the level should be in the "COLD" range. Similarly, if it is hot, the fluid level should be in the "HOT" range. If the level is at the low side of either range, add automatic transmission fluid DEXRONR-II or III to bring the level within range. e. After replacing the filler cap, visually check the steering box case, vane pump and hose connections for leaks or damage. Check the fluid level through the reservoir. If necessary, add automatic transmission fluid DEXRON®II or -III. If the vehicle has been driven around 80 km/h (50 mph) for 20 minutes (a little more in frigid temperatures), the fluid is hot (40_C80_C or 104_F175_F). You may also check the level when the fluid is cold (about room temperature, 0_C 40_C or 32_F104_F) if the engine has not been run for about five hours. a. Clean all dit from outside of the reservoir tank. b. Remove the filler cap by turning it counterclockwise and wipe the dipstick clean. Checking tire pressure Keep your tire pressures at the proper level. The recommended cold tire pressures, tire size and the cargo weight are also given in Part 8. You should check the tire pressures every two weeks, or at least once a month. And don't forget the spare! Incorrect tire pressure can reduce tire life and make your vehicle less safe to drive. Low tire pressure results in excessive wear, poor handling, reduced fuel economy, and the possibility of blowouts from overheated tires. Also, low tire pressure can cause poor sealing of the tread bead. If the tire pressure is excessively low, there is the possibility of wheel deformation and/or tire separation. High tire pressure produces a harsh ride, handling problems, excessive wear at the center of the tire tread, and a greater possibility of tire damage from road hazards. If a tire frequently needs refilling, have it checked by your Toyota dealer. ! CAUTION The reservoir tank may be hot so be careful not to burn yourself. NOTICE Avoid overfilling, or the power steering could be damaged. 185
