TIRE AND WHEEL
INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and proper inflation pressure.
Cold tire inflation pressure:
Tire sizeFront
kPa (kgf/cm2, psi)
Rear
kPa (kgf/cm2, psi)
P275/70R16200 (2.0, 29)
*220 (2.2, 32)220 (2.2, 32)
*240 (2.4, 35)
*: Trailer towing
(b) Check the tire runout.
Tire runout: 3.0 mm (0.118 in.) or less
2. ROTATE TIRE
HINT:
Rotate tires as shown in the illustration.
Rotate as shown in (B) if the spare tire is included in the
rotation.
3. INSPECT WHEEL BALANCE
(a) Check and adjust the Off-the car balance.
(b) If necessary, check and adjust the On-the car balance.
Imbalance after adjustment: 14.0 g (0.031 Ib) or less

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that the transfer shift lever is shifted to the L position.
When switching differential Free e Lock, the indicator light will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated to apply differential
power to the differential, the differential locks and the indicator light lights up.
