5. Tilt the retainer and slip itthrough the wheel opening to
remove the spare tire from the
cable.
6. Turn the wrench clockwise to raise the cable back up after
removing the spare tire.
Do not store a full‐size or a flat
road tire under the vehicle.
See “Storing the Spare Tire”
and “Storing the Flat Tire” later
in this section.
Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. See If a Tire Goes
Flat on page 10‑58 for more
information.
2. If the vehicle has a wheel cover, loosen the plastic nut caps with
the wheel wrench. They will not
come off. Then, using the flat
end of the wheel wrench, pry
along the edge of the cover until
it comes off. Be careful; the
edges may be sharp. Do not try
to remove the cover with your
bare hands.
Store the wheel cover securely
in the rear of the vehicle until
you have the flat tire repaired or
replaced.
If the vehicle has aluminum
wheels, remove the wheel nut
caps using the wheel wrench.
3. Loosen the wheel nuts —but do
not remove them —using the
wrench. For wheels with a wheel
lock key, use the wheel lock key
between the lock nut and
wrench. The key is supplied in
the front passenger door pocket.

Vehicle Care 10-71
Notice:If this vehicle has wheel
locks and an impact wrench is
used to remove the wheel nuts,
the lock nut or wheel lock key
could be damaged. Do not use an
impact wrench to remove the
wheel nuts if this vehicle has
wheel locks.
4. To identify the appropriate
jacking location, find the
triangle (A) about 30.5 cm (12 in)
from the front tire or (B) about
27 cm (10.5 in) from the
rear tire.
The triangle is located near each
wheel on the vehicle's exterior.
Notice: If a jack is used to raise
the vehicle without positioning it
correctly, the vehicle could be
damaged. When raising the
vehicle on a jack, avoid contact
with the rear axle control arms. 5. Attach the wrench to the jack,
and turn the wrench clockwise to
raise the jack head 7.6 cm (3 in).
6. Do not raise the vehicle yet. Put the compact spare tire near you.
{WARNING
Getting under a vehicle when it is
lifted on a jack 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.

10-72 Vehicle Care
{WARNING
Raising the 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 fit the jack lift
head into the proper location
before raising the vehicle.
7. Raise the vehicle by turning the wrench clockwise in the jack.
Raise the vehicle far enough off
the ground so that there is
enough room for the spare tire
to fit under the wheel well.
8. Remove all the wheel nuts and the flat tire.
9. Remove the plastic spare tire
heat shield by pulling the rubber
latch. Store the plastic spare tire
heat shield. See “Storing the
Spare Tire” later in this section
for more information.
{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, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
{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 fromthe 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 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. See Capacities 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.
To avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification.
See Capacities and Specifications
on page 12‑2 for the wheel nut
torque specification.
14. Tighten the wheel nuts firmly in a crisscross sequence,
as shown.
Notice: Wheel covers will not fit
on the 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 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 through the 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 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.

2. Replace the tool bag (A). 3. Turn the jack (C) on its side and
place down on the holding
bracket.
4. Reinstall the wing bolt (B) by turning clockwise.
5. To replace the cover, line up the tab at the front of the cover with
the notch in the cover opening.
Push the cover in place and
make sure that the rear clips are
in the slots and push the cover
closed.
Store the center cap or the plastic
bolt‐on wheel covers until a full size

Compact Spare Tire
{WARNING
Driving with more than one
compact spare tire at a time
could result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
The compact spare tire, if the
vehicle has one, was fully inflated
when the vehicle was new, however,
it can lose air after a time. Check
the inflation pressure regularly.
It should be 420 kPa (60 psi).
After installing the compact spare
on the vehicle, stop as soon as
possible and make sure the
spare tire is correctly inflated. The compact spare is made to
perform well at speeds up to
105 km/h (65 mph) for distances up
to 5 000 km (3,000 mi), so you can
finish 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 fit. Keep the
spare tire and its wheel together.
The All-Wheel Drive (AWD) system
will be automatically disabled
when you use the compact spare.
To restore the AWD and prevent
excessive wear on the clutch in your
AWD, replace the compact spare
tire with a full-size tire as soon as
possible.
Notice:
Tire chains will not fit the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not
use tire chains on the compact
spare.

6. To prevent the battery fromdraining while the vehicle is
being towed, remove the
20 amp ECM1 fuse and the
50 amp BATT1 fuse from the
underhood fuse block and store
in a safe location. See Engine
Compartment Fuse Block on
page 10‑31.
7. Release the parking brake.
Notice: If the vehicle is towed
without performing each of the
steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Notice: If 105 km/h (65 mph) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 105 km/h (65 mph)
while towing the vehicle. Once the destination is reached:
1. Set the parking brake.
2. Reinstall the fuses in the
underhood fuse block.
3. Shift the transmission to P (Park), turn the ignition to
LOCK/OFF and remove the key
from the ignition.
4. Disconnect the vehicle from the towing vehicle.
Notice: Do not tow a vehicle with
the front drive wheels on the
ground if one of the front tires is
a compact spare tire. Towing with
two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.Dolly Towing (All-Wheel‐Drive
Vehicles)
All-wheel‐drive vehicles must not be
towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.
