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 ultimately damage.
●Water can wash the grease from wheel bear ings, causing rusting and premature fail- ure, and may also enter the differential, transmission and transfer (AWD models only)case, reducing the gear o il’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 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.
