c. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weig ht sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual imbalance values are 5 g (0.18 oz) each or below.
• If either residual imbalance value exceeds 5 g (0.18 oz),repeat installation procedures.
Wheel balance (Maximum allowable imbalance):
RotationINFOID:0000000005148247
NOTE:
Follow the maintenance schedule for tire rotation service intervals. Refer to MA-6, "
General Maintenance" .
1. Rotate the tires on each side from front to back as shown. Do not include the spare tire when rotating the tires.
CAUTION:
When installing wheel s, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
2. Adjust the tire pressure to specification. Refer to WT-52, "
Tire" .
3. After the tire rotation, retighten the wheel nuts after the vehicle has been driven for 1,000 km (600 miles), and also after every
wheel and tire have been installed such as after repairing a flat tire.
Maximum allowable imbalance Dynamic (At rim flange) 5 g (0.18 oz) (one side)
Static
10 g (0.35 oz)

FRONT WIPER ARM ADJUSTMENT
1. Operate wiper motor one full cycle, then turn "OFF" (Auto Stop).
2. Lift the wiper blade up and then rest it onto glass surface, check
the blade clearance "L1" and "L2".
3. Remove wiper arm covers and wiper arm nuts.
4. Adjust front wiper arms on wiper motor pivot shafts to obtain above specified blade clearances.
5. Tighten wiper arm nuts to specified torque, and install wiper arm covers. Refer to WW-80, "
