SERVICING AND MAINTENANCE

(Continued)
NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and
tear in existing tires.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a
balance of many characteristics. They should
be inspected regularly for wear and correct
cold tire inflation pressures. The manufac-
turer strongly recommends that you use tires
equivalent to the originals in size, quality
and performance when replacement is
needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig -
nation of your tire. The Load Index and
Speed Symbol for your tire will be found on
the original equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle. WARNING!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire
and wheel sizes with load ratings
approved for your vehicle.
Never use a tire with a smaller load index
or capacity, other than what was origi -
nally equipped on your vehicle. Using a
tire with a smaller load index could result
in tire overloading and failure. You could
lose control and have a collision.
Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.

Wheel And Wheel Trim Care
All wheels and wheel trim, especially
aluminum and chrome plated wheels, should
be cleaned regularly using mild (neutral Ph)
soap and water to maintain their luster and
to prevent corrosion. Wash wheels with the
same soap solution recommended for the
body of the vehicle and remember to always
wash when the surfaces are not hot to the
touch.Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other
road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge
and mild soap to wipe away promptly. Do not
use harsh chemicals or a stiff brush. They
can damage the wheel’s protective coating
that helps keep them from corroding and
tarnishing.
When cleaning extremely dirty wheels
including excessive brake dust, care must be
taken in the selection of tire and wheel
cleaning chemicals and equipment to
prevent damage to the wheels. Select a
non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.
NOTE:
If you intend parking or storing your vehicle
for an extended period after cleaning the
wheels with wheel cleaner, drive your vehicle
and apply the brakes to remove the water
droplets from the brake components. This
activity will remove the red rust on the brake
rotors and prevent vehicle vibration when
braking.
WARNING!
Limited use spares are for emergency use
only. Installation of this limited use spare
tire affects vehicle handling. With this tire,
do not drive more than the speed listed on
the limited use spare wheel. Keep inflated
to the cold tire inflation pressures listed on
your Tire and Loading Information Placard
located on the driver’s side B-Pillar or the
rear edge of the driver’s side door. Replace
(or repair) the original equipment tire at
the first opportunity and reinstall it on your
vehicle. Failure to do so could result in
loss of vehicle control.
CAUTION!

Avoid products or automatic car washes that
use acidic solutions or strong alkaline
additives or harsh brushes. Many aftermarket
wheel cleaners and automatic car washes
may damage the wheel's protective finish.
Such damage is not covered by the New
Vehicle Limited Warranty. Only car wash soap
is recommended.

CAUTION!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products may damage the
wheel's protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap is
recommended.
