NOTICE
■To prevent water damage
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 entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
●Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, 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 driving
●Sand and mud that has accumulated in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
●Always perform a maintenance inspection after each day of off-road driv-
ing 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”.
