NOTICE
■To prevent water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the engine or other
components does not occur.
●Water entering the engine air
intake will cause severe engine
damage.
●Water entering the automatic
transmission will cause deterio-
ration in shift quality, locking up
of your transmission accompa-
nied by vibration, and ultimately
damage.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the differen-
tial, transmission and transfer
case, reducing the gear oil’s
lubricating qualities.
■When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the riverbed for
firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated in bra ke drums and
around brake di scs may affect
braking efficiency and may
damage brake system compo-
nents.
●Always perform a maintenance
inspection aft er each day of
off-road driving that has taken
you through rough terrain, sand,
mud, or water. For scheduled
maintenance information, refer
to the “Scheduled Maintenance
Guide” or “Owner’s Manual
Supplement”.

rately or in combination, can cause
heat buildup and possible tire fail-
ure.
