Caution
If the vehicle is equipped with
195/65R15 or 205/55R16 size
tires, 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. SeeTires
0 301. 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.
{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

Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to
suspension components. Use the
proper straps around the tires to
secure the vehicle.
Use only a flatbed tow truck for
towing a disabled vehicle. Never
use a sling type lift or damage will
occur. Use ramps to help reduce
approach angles if necessary.
A towed vehicle should have its
drive wheels off the ground.
Consult a professional towing
service if the disabled vehicle must
be towed.
Caution
Improper use of the tow eye can
cause vehicle damage. Use
caution and low speeds to
prevent damage to the vehicle.
If the vehicle is equipped with tow
eye, only use the tow eye to pull the
vehicle onto a flatbed car carrier
from a flat road surface. Do not use
the tow eye to pull the vehicle from
snow, mud or sand.
Recreational Vehicle
Towing
Recreational vehicle towing refers to
towing the vehicle behind another
vehicle, such as behind a motor
home. The two most common types
of recreational vehicle towing are
known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly. Here are some important things to
consider before recreational vehicle
towing:
.
The towing capacity of the
towing vehicle. Be sure to read
the tow vehicle manufacturer's
recommendations.
. How far the vehicle will be
towed. Some vehicles have
restrictions on how far and how
long they can tow.
. The proper towing equipment.
See your dealer or trailering
professional for additional advice
and equipment
recommendations.
. Whether the vehicle is ready to
be towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Caution
Use of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the

transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle.
Dinghy Towing (with Automatic
Transmission)
Caution
If the vehicle is towed with all four
wheels on the ground, the
drivetrain components could be
damaged. The repairs would not
be covered by the vehicle
warranty. Do not tow the vehicle
with all four wheels on the
ground.
Vehicles with an automatic
transmission should not be towed
with all four wheels on the ground.
If the vehicle must be towed, a dolly
should be used. See "Dolly Towing"
later in this section.
Dinghy Towing (with Manual
Transmission)
To dinghy tow the vehicle from the
front with all four wheels on the
ground: 1. Position the vehicle to tow and then secure it to the towing
vehicle.
2. Shift the transmission to Neutral.

6. Secure the vehicle to the dolly.
7. Release the parking brake.
Caution
Towing the vehicle from the rear
could damage it. Also, repairs
would not be covered by the
vehicle warranty. Never have the
vehicle towed from the rear.
Appearance Care
Exterior Care
Locks
Locks are lubricated at the factory.
Use a de-icing agent only when
absolutely necessary, and have the
locks greased after using. See
Recommended Fluids and
Lubricants0361.
Washing the Vehicle
To preserve the vehicle's finish,
wash it often and out of direct
sunlight.
Caution
Do not use petroleum-based,
acidic, or abrasive cleaning
agents as they can damage the
vehicle's paint, metal, or plastic
parts. If damage occurs, it would
not be covered by the vehicle
warranty. Approved cleaning
products can be obtained from

your dealer. Follow all
manufacturer directions regarding
correct product usage, necessary
safety precautions, and
appropriate disposal of any
vehicle care product.
Caution
Avoid using high-pressure
washes closer than 30 cm (12 in)
to the surface of the vehicle. Use
of power washers exceeding
8,274 kPa (1,200 psi) can result
in damage or removal of paint
and decals.
Caution
Do not power wash any
component under the hood that
has this
esymbol.
