the wheel’s protective coating that helps keep
them from corroding and tarnishing.
When cleaning extremely dirty wheels
including excessive brake dust, care must be
taken in the selection of tire and wheel
cleaning chemicals and equipment to prevent
damage to the wheels. Select a non-abrasive,
non-acidic cleaner for aluminum or chrome
wheels.
NOTE:

If you intend parking or storing your vehicle for
an extended period after cleaning the wheels
with wheel cleaner, drive your vehicle and
apply the brakes to remove the water droplets
from the brake components. This activity will
remove the red rust on the brake rotors and
prevent vehicle vibration when braking.

Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Trac
-
tion levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Summer Or Three Season Tires — If
Equipped
Summer tires provide traction in both wet and
dry conditions, and are not intended to be
driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold driving
conditions. Install Winter tires on your vehicle
when ambient temperatures are less than
40°F (5°C) or if roads are covered with ice or
snow. For more information, contact an autho -
rized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol on
the tire sidewall. Use Summer tires only in sets
of four; failure to do so may adversely affect
the safety and handling of your vehicle.
Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can
be identified by a “mountain/snowflake”
symbol on the tire sidewall.
If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow
CAUTION!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. Many
aftermarket wheel cleaners and automatic
car washes may damage the wheel's
protective finish. Such damage is not
covered by the New Vehicle Limited
Warranty. Only car wash soap is
recommended.
CAUTION!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products may damage the
wheel's protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap is
recommended.
CAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing
compounds. They will permanently damage
this finish and such damage is not covered
by the New Vehicle Limited Warranty. HAND
WASH ONLY USING MILD SOAP AND WATER
WITH A SOFT CLOTH. Used on a regular
basis; this is all that is required to maintain
this finish.
WARNING!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.

tires only in sets of four; failure to do so may
adversely affect the safety and handling of
your vehicle.
Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at
sustained speeds over 75 mph (120 km/h).
For speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire dealer
for recommended safe operating speeds,
loading and cold tire inflation pressures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of
non-studded tires. Some states prohibit
studded tires; therefore, local laws should be
checked before using these tire types.
Tire Chains and Traction Devices
It is possible to fit 13 mm chains on all the
tires except for R20.
Use of traction devices require sufficient
tire-to-body clearance. Follow these recom-
mendations to guard against damage.

NOTE:

Traction device must be of proper size for
the tire, as recommended by the traction
device manufacturer.
Use on rear tires only.
Check the tension of the snow chains after
the first few meters have been driven.
Using snow chains with tires with non-orig -
inal dimensions may damage the vehicle.
Using different tires sizes or types (M+S,
snow, etc.) between the front and rear axles
may adversely affect vehicle driveability,
with the risk of losing control of the vehicle
and resulting accidents.
Tire Rotation Recommendations
Tires on the front and rear axles of vehicles
operate at different loads and perform
different steering, driving, and braking func -
tions. For these reasons, they wear at unequal
rates. These effects can be reduced by timely
rotation of tires. Rotation will increase tread
life, maintain traction levels and contribute to
a smooth, quiet ride.
To resolve this problem, tires should be
rotated at each service interval (approximately
every 10,000 miles [16,000 km]). More
frequent rotation is permissible if desired. The
reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
Tire Rotations Not Recommended — If
Equipped
Due to different size tires and wheels on front
and rear axles tire rotation is not possible for:
2.0T GME Engine equipped with a different
front and rear tire size.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device
clearance between tires and other
suspension components, it is important
that only traction devices in good condi -
tion are used. Broken devices can cause
serious damage. Stop the vehicle immedi -
ately if noise occurs that could indicate
device breakage. Remove the damaged
parts of the device before further use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device manufac -
turer’s instructions on the method of
installation, operating speed, and condi -
tions for use. Always use the suggested
operating speed of the device manufac -
turer’s if it is less than 30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION! (Continued)

Tire rotation contributes to the preservation of
the grip and traction performance on wet,
muddy or snowy roads, guaranteeing optimal
driveability of the vehicle.
In the case of irregular wear of the tires iden-
tify the cause and correct it as soon as
possible, by contacting an authorized dealer.
The rotational direction of the tire must be
taken into consideration when rotating the
tires. The recommended rotation pattern for
directional tires is shown below.
Tire Rotation
It is recommended to avoid situations with a
large difference in wear between the front and
rear tires and to strictly use Winter tires of the
sizes given on the tire placard. The AWD system and the original tires are
developed together to ensure the vehicle’s
best performance. When changing the tires, it
is recommended to us the same “AR” marked
tires, to maintain the same level of perfor
-
mance and component life.DEPARTMENT OF

TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each cate -
gory is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must
conform to Federal safety require -
ments in addition to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half times
as well on the government course as a
tire graded 100. The relative perfor -
mance of tires depends upon the actual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices, and differences in
road characteristics and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on speci
-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
Temperature Grades
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled condi -
tions on a specified indoor laboratory
CAUTION!
Damage to the vehicle may occur if
different front and rear tire sizes are
rotated
WARNING!
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
