CAUTION

Off-road driving precautions

Always observe the following precautions to minimize the risk of death or serious

injury or damage to your vehicle:

●

Drive carefully when off the road. Do not take unnecessary risks by driving in

dangerous places.

●

Do not grip the steering wheel spokes when driving off-road. A bad bump could

jerk the wheel and injure your hands. Keep both hands and especially your

thumbs on the outside of the rim.

●

Always check your brakes for effectiveness immediately after driving in sand,

mud, water or snow.

●

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 vehi-

cle rollover causing death or serious injury. You are also risking expensive dam-

age to your vehicle’s suspension and chassis.

NOTICE

■

To prevent the 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.
