Tire Chains
{CAUTION:
If your vehicle has P225/55R17, P255/45R18 or
P225/50R18 size tires, do not use tire chains,
there is not enough clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause damage
to the brakes, suspension or other vehicle
parts. The area damaged by the tire chains
could cause you to lose control of your vehicle
and you or others may be injured in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions.
CAUTION: (Continued)
CAUTION: (Continued)
To help avoid damage to your vehicle, drive
slowly, readjust or remove the device if it is
contacting your vehicle, and do not spin your
wheels.
If you do nd traction devices that will t,
install them on the front tires.
Notice:If your vehicle does not have P225/55R17,
P255/45R18 or P225/50R18 size tires, use tire chains
only where legal and only when you must. Use only
SAE Class S-type chains that are the proper size for
your tires. Install them on the front tires and tighten
them as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and retighten
them. If the contact continues, slow down until it
stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.

Storing a Flat or Spare Tire and
Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone.
Store all these in the proper place.
After the compact spare tire is put on the vehicle, store
the at tire in the trunk. Use the following procedure
to secure it in the trunk. When storing a full-size tire, use
the extension and protector/guide, located in the foam
holder, to help avoid wheel surface damage.To store a full-size tire:
1. Install the tools in their original location in the trunk
area and secure.
2. Place the tire in the trunk with the valve stem facing
down, and the protector/guide placed through a
wheel bolt hole.
3. Remove the protector and attach the retainer
securely.
4. Place the protector/guide back in the foam holder
when putting the compact spare back in the trunk.
Store the cover as far forward as possible.
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size tire as
soon as possible. SeeCompact Spare Tire on
page 5-109for more information. Use the following as a
guide for storing the compact spare tire and tools.

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
nish your trip and have the full-size tire repaired or
replaced where you want. You must calibrate the tire
ination monitor system, if your vehicle has this feature,
after installing or removing the compact spare. SeeTire
Pressure Monitor System on page 5-71. 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 your vehicle through an automatic car wash
with guide rails. The compact spare can get
caught on the rails. That can damage the tire and
wheel, and maybe other parts of your 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 your compact spare.
Using them can damage your vehicle and can
damage the chains too. Do not use tire chains on
your compact spare.
Appearance Care
Interior Cleaning
Your vehicle’s interior will continue to look its best if it is
cleaned often. Although not always visible, dust and dirt
can accumulate on your upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles from
your upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled. Soils should
be removed as quickly as possible. Your vehicle’s interior
may experience extremes of heat that could cause stains
to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.
