DRIVING TIPS
413
NOTICE
If driving through water, such as when crossing
shallow streams, first check the depth of the water
and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
Take all necessary safety measures to ensure that
water damage to the engine or other components
does not occur.
Water entering the engine air intake will cause severe
engine damage.
Water can wash the grease from wheel bearings,
causing rusting and premature failure, and may also
enter the differentials, transmission and transfer
case, reducing the gear oil's lubricating qualities.
Sand and mud that has accumulated in brake drums
and around brake discs may affect braking efficiency
and may damage brake system components.
Always perform a maintenance inspection after each
day of off-road driving that has taken you through
rough terrain, sand, mud, or water. For scheduled
maintenance information, refer to the Owner's
Manual Supplement/Scheduled Maintenanceº.

MAINTENANCE
491 Brakes

the vehicle has been parked for a while. If you smell fuel fumes
or notice any leak, have the cause found and corrected
immediately.
Doors and engine hood
Check that all side doors and back door, operate smoothly and
all latches lock securely. Make sure the engine hood
secondary latch secures the hood when the primary latch is
released.
Tire inflation pressure
Check the pressure with a gauge every two weeks,
or at least once a month and adjust as shown on the
tire pressure label. See page 532 for additional
information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 545 for additional
information.
Wheel nuts
When checking the tires, make sure to check the nuts
for looseness. Tighten them if necessary.
