N ENGINE SPEED SENSING POWER STEERING Caution Never hold the steering wheel to the extreme left or right for more than five seconds with the engine running. This could damage the power steering d pump- 8. Turn the steering wheel fully to the left and right and measure the fluid pressure generated by the gear hous- ing. If the pressure is not within specification, replace the gear housing assembly. Gear housing fluid pressure: 7,601--8,335 kPa (77.545.0 kgflcm2, 1,103-1,208 psi) 9. Remove the gauge set. Install and tighten the pressure hose to the specified torque. Tightening torque: 3247 N.m (3.24.8 kgf.m, 24--34 ft.lbf} 10. Bleed the air from the system. (Refer to page N-21.) STEERING WHEEL AND COLUMN Obtain the code number and deactivate the audio anti- theft system before disconnecting the battery. (Refer to section T.) On-vehicle Inspection -1 Steering wheel effort 1. With the vehicle on a hard, level surface, put the wheels in the straight-ahead position. 2. Start the engine and warm the power steering fluid to 50--60°C (1 22-1 40°F). 3. With the engine running at idle, attach a pull scale to the outermost point of the steering wheel spoke. Then, starting with the wheels in the straight-ahead posi- tion, measure the effort required to turn the steering wheel to the left and to the right. Steering wheel effort: 2635 N (2.63.6 kgf, 5.3-7.9 Ibf) (during one turn of the steering wheel) 2 4. If not within specification, check the following: fluid level, air in system, fluid leakage at hose or connections, func- tion of oil pump and steering gear, and tire pressure. Gartner Banana

WHEELS AND TIRES Q WHEELS AND TIRES SPECIAL NOTES ABOUT WHEELS AND TIRES ,, 1. Do not use wheels or tires other than those types specified. 2. Aluminum wheels are easily scratched. When washing them, use a soft cloth, never a wire brush. If the vehicle is steam cleaned, do not allow boiling water to contact the wheels. 3. If alkaline compounds (such as salt-water or road salts) get on aluminum wheels, wash them as soon as possible to prevent damage. Use only a neutral detergent. - - 9MUOQX-004 NOTES REGARDING TIRE REPLACEMENT Note the following points when tires are to be removed from or mounted onto the wheels. 1. Be careful not to damage the tire bead, the rim bead, or the edge of the rim. 2. Apply a soapy solution to the tire bead and the edge of the rim. 3. Use a wire brush, sandpaper, or cloth to clean and remove all rust and dirt from the rim edge and the rim bead. For aluminum wheels, use only a cloth for this purpose; never use a wire brush or sandpaper. 4. Remove pebbles, glass, nails, and other foreign items embedded in the tire tread. 5. Be sure the air valve is installed correctly. 6. After mounting a tire on a wheel, inflate it to 250-300 kPa I2.55--3.06 kgf/cm2, 35.55--42.66 psi). Verify that the bead is seated correctly on the rim and that there are no air leaks. Then reduce the pres- sure to the specified level. 7. If a tire iron is used to change a tire on an aluminum wheel, be sure to use a piece of rubber between the iron lever and the wheel to avoid damage to the wheel. Work should be done on a rubber mat, not on a hard or rough surface. INSPECTION / ADJUSTMENT Check the following and adjust or replace as necessary. 1. Air pressure. Check the air pressure of all tires when they are cold, including the spare tire, with an air pressure gauge. u Air pressure: Standard tires 177 kPa (1.8 kgf/cm2, 26 psi) Temporary spare tires 412 kPa (4.2 kgf/cm2, 60 psi) 2. Wheel runout. Set the probe of a dial indicator against the wheel, and turn the wheel one full revolution. WEAR INDICATOR Wheel runout: Horizontal 2.0mm (0.079 in) max. Vertical 1.5mm (0.059 in) max. WEAR lNDICAToR 3. Tire wear. Specifications Remaining tread Ordinary tires: 1.6mm (0.063 in) min. (Tire should be replaced if wear indicators are exposed.) Snow tires: 50% of tread (Tire should be replaced if wear indicators are exposed .) Gartner Banana
