{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under a
vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even make
the vehicle fall. To help avoid personal injury and
vehicle damage, be sure to t the jack lift head into
the proper location before raising the vehicle.
Notice:If you position the jack under the rocker
molding and attempt to raise the vehicle, you could
break the molding and/or cause other damage to your
vehicle. Always position the jack so that when the
jack head is raised, it will t rmly in the notch
located inboard from the rocker molding.5. Turn the jack handle counterclockwise to lower the
jack lift head until the jack ts under the vehicle.

{CAUTION:
Rust or dirt on a wheel, or on the parts to which it
is fastened, can make wheel nuts become loose
after time. The wheel could come off and cause
an accident. When changing a wheel, remove any
rust or dirt from places where the wheel attaches
to the vehicle. In an emergency, use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if needed, to get all the
rust or dirt off. SeeChanging a Flat Tire on
page 5-74.
11. Place the spare tire on the wheel-mounting surface.
{CAUTION:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle’s wheel
could fall off, causing a crash.
12. Put the wheel nuts back
on with the rounded
end of the nuts toward
the wheel. Tighten each
nut by hand until the
wheel is held against
the hub.

13. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
{CAUTION:
Wheel nuts that are improperly or incorrectly
tightened can cause the wheels to become loose
or come off. The wheel nuts should be tightened
with a torque wrench to the proper torque
specication after replacing. Follow the torque
specication supplied by the aftermarket
manufacturer when using accessory locking wheel
nuts. SeeCapacities and Specifications on
page 5-103for original equipment wheel nut
torque specications.
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 5-103for the wheel nut torque specication.

14. Tighten the wheel nuts rmly in a crisscross
sequence as shown.
If your vehicle is equipped with wheel nut covers,
screw the nut covers on with your ngers, then
tighten one-quarter turn with the wheel wrench.
Notice:Wheel covers will not t on your vehicle’s
compact spare. If you try to put a wheel cover on the
compact spare, the cover or the spare could be
damaged.
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 you have put the spare tire on your vehicle, store
the at tire in your trunk.
Store the at tire as far forward in the trunk as possible.
Store the jack and wheel wrench in their compartment
in the trunk. For storage, the jack must be raised
until the screw end is ush with the edge of the jack.

Spare Tire
Compact Spare Tire
Your vehicle may have a 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, 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 at your
convenience. Of course, it is best to replace the spare
with a full-size tire as soon as possible. The spare tire
will last longer and be in good shape in case it is
needed 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.Spare Tire
Your vehicle may have a spare tire, which, when new,
was fully inated. A spare tire may lose air over time, so
check its ination pressure regularly. SeeInflation -
Tire Pressure on page 5-57andLoading the Vehicle on
page 4-19for information regarding proper tire ination
and loading your vehicle. For instructions on how to
remove, install or store a spare tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-77.
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 tire originally installed on your vehicle.
This spare tire was developed for use on your vehicle,
so it is 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
Interior Cleaning
The vehicle’s interior will continue to look its best if it is
cleaned often. Although not always visible, dust and
dirt can accumulate on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles from the
upholstery. It is important to keep the upholstery from
becoming and remaining heavily soiled. Soils should be
removed as quickly as possible. The 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 home furnishings may also
transfer color to the vehicle’s interior.
When cleaning the vehicle’s interior, only use cleaners
specically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.Notice:Using abrasive cleaners when cleaning
glass surfaces on the vehicle, could scratch the glass
and/or cause damage to the rear window defogger.
When cleaning the glass on the vehicle, use only a
soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in the vehicle’s breathing space. Before
using cleaners, read and adhere to all safety instructions
on the label. While cleaning the vehicle’s interior,
maintain adequate ventilation by opening the vehicle’s
doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Products that remove odors from the vehicle’s upholstery
and clean the vehicle’s glass can be obtained from your
dealer/retailer.
Do not clean the vehicle using:
A knife or any other sharp object to remove a soil
from any interior surface.
A stiff brush. It can cause damage to the vehicle’s
interior surfaces.
Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
