The wiring circuits in the vehicle
are protected from short circuits by
fuses. This greatly reduces the

inside the fuse. If the band is
broken or melted, replace the fuse.
Be sure to replace a bad fuse
with a new one of the identical size
and rating.

compartment and one in the trunk.
There is a fuse puller located on
the rear compartment fuse block.

Tires
Your new vehicle comes with
high-quality tires made by
a leading tire manufacturer.
If you ever have questions about
the tire warranty and where to
obtain service, see the “Limited
Warranty, Maintenance and
Owner Assistance Information”
manual for details. For additional
information refer to the tire
manufacturer.{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your tires can
cause overheating as a
result of too much exing.
You could have an air-out
and a serious accident.
SeeLoading the Vehicle
on page 8-30.
Underinated tires pose
the same danger as
overloaded tires.
The resulting accident
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when
your tires are cold. See
Inflation - Tire Pressure on
page 9-47.
(Continued)
CAUTION (Continued)
Overinated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
you hit a pothole. Keep
tires at the recommended
pressure.
Worn, old tires can cause
accidents. If your tread is
badly worn, or if your tires
have been damaged,
replace them.
SeeHigh-Speed Operation
on page 9-48for ination
pressure adjustment for high
speed driving.
