Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you are
going to drive before you begin driving.
Highway driving
Tires
OJF055200
Adjust the tire inflation pressures to
specification. Low tire inflation pres‐
sures will result in overheating and pos‐
sible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction or
tire failure.
NOTICE
Never exceed the maximum tire in‐
flation pressure shown on the tires.
WARNING
• Underinflated or overinflated tires
can cause poor handling, loss of
vehicle control, and sudden tire
failure leading to accidents, inju‐
ries, and even death. Always check
the tires for proper inflation be‐
fore driving. For proper tire pres‐
sures, refer to Tires and wheels
on page 9-11.
• Driving on tires with no or insuffi‐
cient tread is dangerous. Worn-out
tires can result in loss of vehicle
control, collisions, injury, and even
death. Worn-out tires should be
replaced as soon as possible and
should never be used for driving.
Always check the tire tread before
driving your vehicle. For further in‐
formation and tread limits, refer
to Tires and wheels on page
9-11.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.
Drive belt
A loose or damaged drive belt may re‐
sult in overheating of the engine.
