specication.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque
specication. SeeCapacities and Specifications on
page 5-134for the wheel nut torque specication.15. Tighten the wheel nuts
rmly in a crisscross
sequence as shown.

Compact Spare Tire
Although the compact spare tire was fully inated
when the vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on the vehicle, you
should stop as soon as possible and make sure the spare
tire is correctly inated. The compact spare is made to
perform well at speeds up to 65 mph (105 km/h) for
distances up to 3,000 miles (5 000 km), so you can nishyour trip and have the full-size tire repaired or replaced
where you want. You must calibrate the tire ination
monitor system after installing or removing the compact
spare. SeeTire Pressure Monitor System on page 5-66.
The system may not work correctly when the compact
spare is installed on the vehicle. Of course, it’s best to
replace the spare with a full-size tire as soon as you can.
The spare will last longer and be in good shape in case
you need it again.
Notice:When the compact spare is installed,
do not take the vehicle through an automatic car
wash with guide rails. The compact spare can
get caught on the rails which can damage the
tire, wheel and other parts of the vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or wheel with
other wheels or tires. They will not t. Keep the
spare tire and its wheel together.
Notice:Tire chains will not t the compact spare.
Using them can damage the vehicle and can damage
the chains too. Do not use tire chains on the
compact spare.

Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer uid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
Extreme dusty conditions
Sand and salt
Heat and sun
Snow and ice, without proper removal
Aluminum or Chrome-Plated Wheels
and Trim
Your vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.Notice:Chrome wheels and other chrome trim
may be damaged if the vehicle is not washed after
driving on roads that have been sprayed with
magnesium, calcium or sodium chloride. These
chlorides are used on roads for conditions such
as ice and dust. Always wash the vehicle’s chrome
with soap and water after exposure.
Notice:Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the warranty. Use only
approved cleaners on aluminum or chrome-plated
wheels.
The surface of these wheels is similar to the painted
surface of your vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes
on them because you could damage the surface.
Do not use chrome polish on aluminum wheels.
Notice:Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by the warranty. Use chrome polish on
chrome wheels only.
Use chrome polish only on chrome-plated wheels, but
avoid any painted surface of the wheel, and buff off
immediately after application.
5-120

Notice:Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the warranty. Never drive a vehicle
equipped with aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on the vehicle may damage the paint nish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces
on the vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to parts repaired or
replaced to restore corrosion protection.
Original manufacturer replacement parts will provide
the corrosion protection while maintaining the vehicle
warranty.
Finish Damage
Any stone chips, fractures or deep scratches in the
nish should be repaired right away. Bare metal
will corrode quickly and may develop into major
repair expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer/retailer.
Larger areas of nish damage can be corrected in your
dealer’s/retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are
not removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, oor pan,
and exhaust system even though they have corrosion
protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close areas
of the frame should be loosened before being ushed.
Your dealer/retailer or an underbody car washing system
can do this.
