3-7. Utility vehicle precautions
WARNING
After driving through tall grass, mud, rock, sand, water, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped to the underbody. Clear
off any such matter from the underbody. If the vehicle is used with these materials
trapped or adhering to the underbody, a breakdown or fire could occur.
When driving off-road or in rugged terrain, do not drive at excessive speeds, jump,
make sharp turns, strike objects, etc. This may cause loss of control or vehicle rollover
causing death or serious injury. You are also risking expensive damage to your
vehicle' s suspension and chassis.
NOTICE
To prevent water damage
Take all necessary safety measures to ensure that water damage to the hybrid battery
(traction 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 and rear electric motor (traction motor) will
cause deterioration in transmission 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 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 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. For scheduled maintenance
information, refer to the "Warranty and Services Guide/Owner' s Manual Supple-
ment/Scheduled Maintenance".
