Tire Chains
{WARNING
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 the vehicle and you or
others may be injured in a crash.
A Type S low-profile cable can be
used only if the cable
manufacturer recommends it for
use on the vehicle, the tire size
combination, and road conditions.
Follow the manufacturer's
instructions. To help avoid
damage to the vehicle, drive
slowly, readjust or remove the
cable if it is contacting the vehicle
and do not spin the vehicle's tires.(Continued)
WARNING (Continued)
Install the cables on the front tires
only. Cables should not be
installed on the spare tire or on
the optional 19-inch tire.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. 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
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.

center cap away from the wheel
to remove it. Store the wheel
cover in the cargo area until you
have the flat tire repaired or
replaced.
3. Turn the wheel wrenchcounterclockwise to loosen all

{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.
11. Remove any rust or dirt fromthe wheel bolts, mounting
surfaces, and spare wheel.
12. Place the compact spare tire on the wheel-mounting surface.
{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.
13. Reinstall the wheel nuts. Tighten each nut by hand until
the wheel is held against
the hub.
14. Lower the vehicle by turning the jack handle
counterclockwise.

When reinstalling the wheel cover or
center cap on the full-size tire,
tighten all five 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.
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 a Flat or Spare Tire
and Tools
{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 flat tire:
1. Remove the cable package. The
cable is stored in a plastic bag
under the compact spare tire.
2. Remove the small center cap by tapping the back of the cap with
the extension of the shaft, if the
vehicle has aluminum wheels.
3. Put the flat tire in the rear storage area with the valve stem
pointing toward the rear of the
vehicle.

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 the
vehicle was new; however, it can
lose air after a 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 installing the spare on
the vehicle. The compact spare is
designed to perform well at speeds
up to 105 km/h (65 mph) for
distances up to 5 000 km (3,000 mi),
so a trip can be completed and the
full-size tire repaired or replaced
when possible. However, the
compact spare tire will last longer
and be in good shape if it is
replaced as soon as possible.
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.
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.
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 fuse 32,
the Discrete Logic Ignition
Switch fuse, from the instrument
panel fuse block and store it in a
safe location. See Instrument
Panel Fuse Block on
page 10‑42.
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 has been
reached:
1. Set the parking brake.
2. Shift the transmission to
P (Park).
3. Turn the ignition key to LOCK/OFF.
4. Install fuse 32, the Discrete Logic Ignition Switch fuse. See
Instrument Panel Fuse Block on
page 10‑42.
5. Start the engine and let it idle for more than three minutes before
driving the vehicle.
Notice: Too much or too little
fluid can damage the
transmission. Be sure that the
transmission fluid is at the proper
level before towing with all four
wheels on the ground. 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 should 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.
