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

Repair or replace suspension parts Repair or replace Balance or replace Correct or replace Correct or replace Rotate tires Caution Applying oil to the lug nuts, bolts, or wheels will cause the lug nuts to become loosened. Tighten the lug nuts to the specified torque in a criss- cross fashion. Verify that the wheel-to-hub contact surfaces are clean. Tightening torque: 88-11 8 N.m (9-1 2 kgf.m, 65--87 ft-lbf) Gartner Banana

WHEEL ALIGNMENT WHEEL ALIGNMENT FRONT WHEEL ALIGNMENT Specifications (Unladed*l) PRE-INSPECTION 1. Check the tire inflations, and adjust to the recommended d pressure if necessary. 2. lnspect the front wheel bearing play and correct if neces- sary. 3. lnspect the wheel and tire runouts. 4. Inspect the ball joints and steering linkage for excessive looseness. 5. The vehicle must be on level ground and carry no lug- gage or passengers. 6. Measure the height from the center of the wheel to the fender brim. The difference between left and right mea- surement must not exceed 10mm (0.39 in), and the rear measurement must be larger then the front measure- ment by 10-30mm (0.4--1.1 in). Caution The proper caster and camber angle vary depend- ing on the vehicle height. Refer to the following and to page R-9 for the specifications. Inspection and adjustment of wheel alignment must be done with the vehicle unladed*'. . .

Using a speedometer tester, check the speedometer for allowable indication error, and check the operation of the odometer. Replace if necessary. 2. Check the speedometer for fluctuation and/or abnormal noise. If there is fluctuation or if the speedometer does not move, remove and inspect the speedometer cable. If it is in good condition, replace the speedometer as- sembly. TACHOMETER lnspection 1. Connect a test tachometer to the engine, and start the engine. 2. Check the tachometer for allowable indication error. Re- place if necessary. lnspection 1. Remove the instrument cluster. (Refer to page T-29.) 2. Apply battery positive voltage to terminal 2K and ground to terminal 2J. 3. Connect the red lead of the SST to terminal 2L and the black lead to ground. 49 0839 285 Checker, fuel and thermometer For inspection of gauges ( ) ... CANADA ONLY I I 45UOTX-050 183R 2on (I sn) 4. Set the SST to the resistance values shown in the figure. To get an accurate reading, wait 2 minutes after setting each value. 5. Verify that the gauge indicates the correct values. The al- lowable indication error is twice the width of the needle. 6. If not as specified, replace the water temperature gauge. -/' Gartner Banana
