2-5. Driving information
NOTICE

To prevent water damage
Take all necessary safety measures to ensure that water damage to the
hybrid battery, 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 trans-
mission quality. The malfunction indicator may come on, and the vehicle
may not be drivable.

Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the hybrid transmission case, reducing
the gear oil's lubricating qualities.
NOTICE

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 around brake discs may affect brak-
ing efficiency and may damage brake system components.

Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water.
