cautions to ensure your driving
enjoyment and to help prevent the
closure of areas to off-road vehi-
cles:
Drive your vehicle only in areas
where off-road vehicles are per-
mitted to travel.
Respect private property. Get
owner’s permission before enter-
ing private property.
Do not enter areas that are
closed. Honor gates, barriers
and signs that restrict travel.
Stay on established roads. When
conditions are wet, driving tech-
niques should be changed or
travel delayed to prevent dam-
age to roads.
WARNING
■Off-road driving precautions
Always observe the following precau- tions to minimize the risk of death, serious injury or damage to your vehi-
cle:
●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 effec-tiveness immediately after driving in sand, mud, water or snow.
●After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or trapped on 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 break-
down 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 the 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 compart-
ment may cause severe damage to the hybrid system.
●Water entering the hybrid transmis-sion will cause deterioration in transmission quality. The malfunc-
tion 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 transaxle case, reducing the gear oil’s lubri-cating qualities.
