{WARNING
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area
that has no fresh air ventilation.
For more information, seeEngine
Exhaust on page 9‑24.
{WARNING
Overinflating a tire could cause
the tire to rupture and you
or others could be injured.
Be sure to read and follow the
tire sealant and compressor kit
instructions and inflate the tire
to its recommended pressure.
Do not exceed the recommended
pressure.
{WARNING
Storing the tire sealant and
compressor kit 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 the tire
sealant and compressor kit in
its original location. If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire, tire changing equipment,
and on some vehicles there may not
be a place to store a tire.
The tire sealant and compressor
can be used to temporarily seal
punctures up to 6 mm (¼ in) in the
tread area of the tire. It can also be
used to inflate an underinflated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire is
too severely damaged for the tire
sealant and compressor kit to be
effective. See
Roadside Assistance
Program (U.S. and Canada) on
page 13‑8 orRoadside Assistance
Program (Mexico) on page 13‑10.
Read and follow all of the tire
sealant and compressor kit
instructions.

{WARNING
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. SeeIf a Tire
Goes Flat on page 10‑61.
{WARNING
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. 10. Remove any rust or dirt from
the wheel bolts, mounting
surfaces, and spare wheel.
11. Place the spare tire on the wheel mounting surface.
12. Put the nuts on by hand by turning them clockwise until
the wheel is held against the
mounting surface. Make sure
the rounded end is toward the
wheel.
13. Lower the vehicle by attaching the lug wrench to the jack
and turning the wrench
counterclockwise. Lower
the jack completely.
{WARNING
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 specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications on page 12‑2
for original equipment wheel
nut torque specifications.
Notice: Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage.

the compact spare, the cover or
the spare could be damaged.
Storing the Spare Tire
{WARNING
The underbody-mounted spare
tire needs to be stored with
the valve stem pointing down.
If the spare tire is stored with
the valve stem pointing upwards,
the secondary latch will not work
properly and the spare tire could
loosen and suddenly fall from the
vehicle. If this happened when
the vehicle was being driven, the
tire might contact a person or
another vehicle, causing injury
and damage to itself. Be sure the
underbody-mounted spare tire
is stored with the valve stem
pointing down.
{WARNING
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.
To store the spare tire:
1. Lay the compact spare tire near the rear of the vehicle with the
valve stem down.
2. Reinstall the plastic spare tire heat shield on the compact
spare tire.

3. Slide the cable retainer throughthe center of the wheel and start
to raise the compact spare tire.
Make sure the retainer is fully
seated across the underside of
the wheel.
4. When the compact spare tire is almost in the stored position,
turn the tire so the valve is
toward the rear of the vehicle.
This position helps when
checking the air pressure
in the compact spare tire.
5. Raise the tire fully against the underside of the vehicle.
Continue turning the lug wrench
until you feel more than two
clicks. This indicates that the
compact spare tire is secure and
the cable is tight. The spare tire
hoist cannot be overtightened.
6. Make sure the tire is storedsecurely. Push, pull (A), and then
try to turn (B) the tire. If the tire
moves, use the lug wrench to
tighten the cable.
Storing the Flat Tire
