Caution
If the vehicle is equipped with a tire
size other than 265/45R21, use tire
chains only where legal and only
when necessary. Use low profile
chains that add no more than
12 mm thickness to the tire tread
and inner sidewall. Use chains that
are the proper size for the tires.
Install them on the tires of the
front axle. Do not use chains on the
tires of the rear axle. Tighten them
as tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer's
instructions. If the chains contact
the 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 the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires are
maintained properly. SeeTires0289. If air goes out of a tire, it is much
more likely to leak out slowly. But if
there ever is a blowout, here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire creates
a drag that pulls the vehicle toward
that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, and then gently brake to a
stop, well off the road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction as used in
a skid. Stop pressing the accelerator
pedal and steer to straighten the
vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off
the road, if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
(Continued)
Warning (Continued)
underinflated or flat may cause a
blowout and a serious crash. Never
attempt to re-inflate a tire that has
been driven on while severely
underinflated or flat. Have your
dealer or an authorized tire service
center repair or replace the flat tire
as soon as possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a flat
tire. If it is used for anything else,
you or others could be badly injured
or killed if the vehicle slips off the
jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.

14. Tighten the wheel nuts firmly ina crisscross sequence, as shown.
15. Lower the jack all the way and remove the jack from under the
vehicle.
16. Tighten the wheel nuts firmly with the wheel wrench.
When reinstalling the wheel cover or
center cap on the full-size tire, tighten
all six plastic caps hand snug with the
aid of the wheel wrench and tighten
them with the wheel wrench an
additional one-quarter of a turn.
Caution
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.
{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.
Storing the Flat Tire
1. Liftgate Hinges
2. Cable
3. Center of the Wheel
4. Door Striker

To store the flat tire:
1. Remove the cable package fromunder the spare tire, jack, and
tools.
2. Remove the small cap by tapping the back of the cap with the
extension of the shaft, if the
vehicle has aluminum wheels.
3. Put the jack, tool container, and cargo management system tray
back in their original location.
4. Put the flat tire in the cargo bin with the valve stem facing the
rear of the vehicle. 5. Pull the cable through the door
striker and the center of the
wheel.
6. Open the lift gate to 3 / 4 door
location and adjust the door
automatically or manually until
there is enough space to hook
the cable to the door hinges. See
Liftgate 021.
7. Hook the other end of the cable onto the outside portion of the
liftgate hinge on the other side of
the vehicle.
8. Pull on the cable to make sure it is secure.
9. Make sure the metal tube is
centered at the striker. Push the
tube toward the front of the
vehicle.
10. Close the liftgate and make sure it is fully latched.
The compact spare is for temporary
use only. Replace the compact spare
tire with a full-size tire as soon as
possible.

2. Lift the load floor.
3. Remove the cargo managementsystem tray.
4. Put back the spare tire and all tools as they were stored in the
rear storage compartment.
5. Install the cargo management system tray and load floor.
The compact spare is for temporary
use only. Replace the compact spare
tire with a full-size tire as soon as
possible.
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. If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure regularly.
It should be 420 kPa (60 psi).
Stop as soon as possible and check
that the spare tire is correctly inflated
after being installed on the vehicle.
The compact spare tire is designed for
temporary use only. The vehicle will
perform differently with the spare tire
installed and it is recommended that
the vehicle speed be limited to
80 km/h (50 mph). To conserve the
tread of the spare tire, have the
standard tire repaired or replaced as
soon as convenient and return the
spare tire to the storage area.
When using a compact spare tire, the
ABS and Traction Control systems
may engage until the spare tire is
recognized by the vehicle, especially
on slippery roads. Adjust driving to
reduce possible wheel slip.
Performance of the All-Wheel
Drive (AWD) system will be
automatically reduced to protect the
system when using the compact spare.
To restore the AWD and prevent excessive wear on the clutch in the
AWD, replace the compact spare tire
with a full-size tire as soon as
possible.
Caution
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.
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.
Caution
Tire chains will not fit the compact
spare. Using them can damage the
vehicle and the chains. Do not use
tire chains on the compact spare.
