When driving
LX570_OM_OM60L96U_(U) NOTICE■
To prevent the 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 qual-
ity, locking up of your transmission accompanied by vibration, and ultimately
damage. ●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differen tials, 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 river bed 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 components.●
Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or wa ter. For scheduled mainte-
nance information, refer to the “Warra nty and Services Guide/Owner’s Manual
Supplement/Schedul ed Maintenance”.
