5-5. Driving tips
Driving
event that off-road driving cannot
be avoided, please observe the fol-
lowing precautions to help avoid
the areas prohibited to vehicles.
 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 or 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, 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 under-
body. 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 traction battery, EV system or other
components does not occur.
●Water entering the motor compart- ment may cause severe damage to
the EV system.
●Water entering the transmission will
cause deterioration in transmission quality. 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 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.
