■
To prevent water damage
Take all necessary safety measures to ensure that water damage to the hybrid bat-
tery, hybrid system or other components does not occur.
●
Water entering the engine compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery stowed under
the rear seats to short circuit.
●
Water entering the hybrid transmission will cause deterioration in transmission
quality. The malfunction indicator may come on, and the vehicle may not be driv-
able.
●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the hybrid transmission 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 around brake discs may affect braking effi-
ciency 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 mainte-
nance information, refer to the “Warranty and Services Guide/Owner’s Manual
Supplement/Scheduled Maintenance”.
