Checking tire pressure 1. Clean all dirt off the outside of the reservoir. 2. Remove the filler cap by turning it counterclockwise and wipe the dipstick clean. 3. Reinstall the filler cap. 4. Remove the filler cap again and look at the fluid level. If the fluid is cold, the level should be in the "COLD" range on the dipstick. 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 Toyota P.S fluid EH or equivalent to bring the level within the range. 5. After replacing the filler cap, visually check the steering box case, vane pump and hose connections for leaks or damage. Low tire pressure results in excessive wear, poor handling, reduced power saving, and the possibility of blowouts from overheated tires. Also, low tire pressure can cause poor sealing of the tire 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 EV service station. Keep your tire pressures at the proper level. When you inspect or adjust tire pressure, please note that tire pressures on your electric vehicle are higher than those of ordinary vehicle. The recommended cold tire pressures, tire sizes and the vehicle capacity weight are given in Part 9. They are also on the tire pressure label as shown. You should check the tire pressures every two weeks, or at least once a month. And do not forget the spare! Incorrect tire pressure can reduce tire life and make your vehicle less safe to drive. The following instructions for checking tire pressure should be observed: D The pressure should be checked only when the tires are cold. If your vehicle has been parked for at least 3 hours and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tire pressure reading. CAUTION The reservoir tank may be hot so be careful not to burn yourself. D Always use a tire pressure gauge. The appearance of a tire can be misleading. Besides, tire pressures that are even just a few pounds off can degrade handling and ride. NOTICE Avoid overfilling, or the power steering could be damaged. 161
