Spare Tire
Your vehicle, when new, had a fully inated spare tire.
A spare tire may lose air over time, so check its
ination pressure regularly. SeeInation - Tire Pressure
on page 5-68andLoading Your Vehicle on page 4-67
for information regarding proper tire ination and loading
your vehicle. For instruction on how to remove, install
or store a spare tire, seeChanging a Flat Tire on
page 5-79.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. Have the damaged or at road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
Your vehicle may have a different size spare tire than
the road tires— those originally installed on your vehicle.
This spare tires was developed for use on your
vehicle, so it’s all right to drive on it.
If your vehicle has a spare tire that does not match your
vehicle’s original road tires and wheels in size and
type, do not include the spare in the tire rotation.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into ames if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed
space. When you use anything from a container to clean
your vehicle, be sure to follow the manufacturer’s
warnings and instructions. And always open your doors
or windows when you are cleaning the inside.
Never use these to clean your vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous — some more than
others — and they can all damage your vehicle, too.

Cleaning Aluminum or Chrome-Plated
Wheels
Your vehicle will have either aluminum or chrome-plated
wheels.
Keep your 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.
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.
Use chrome polish only on chrome-plated wheels but
avoid any painted surface of the wheel, and buff
off immediately after application.
Do not take your vehicle through an automatic car wash
that has silicone carbide tire cleaning brushes. These
brushes can also damage the surface of these wheels.
Cleaning Tires
To clean your tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the paint
nish and/or tires. When applying a tire dressing,
always wipe off any overspray from all painted
surfaces on your vehicle.
Sheet Metal Damage
If your 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 warranty.
