When driving
Tire chainsTire chains cannot be used on your vehicle because of the lack of
clearance between the tires and vehicle body.
When tire chains cannot be used, use of another type of traction
device (such as spring chains) may be acceptable if use on your vehi-
cle is recommended by the device manufacturer, taking into account
tire size and road conditions.
Follow the device manufacturer's instructions, especially regarding
maximum vehicle speed.
To help avoid damage to your vehicle, drive slowly, readjust or
remove the device if it is contacting your vehicle, and do not spin your
wheels. Damage caused to your vehicle by use of a traction device is
not covered under warranty.
Make certain that any traction device you use is an SAE class “S”
device, and use it on the rear wheels only.
Always use the utmost care when driving with a traction device. Over-
confidence because you are using a traction device could easily lead
to a serious accident.
Selecting tire chainsWe recommend that you consult your SUBARU dealer for information
about the chains that you can use.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
Perform the following to protect the vehicle and maintain it in prime
condition.
● Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any
dirt and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.

Maintenance and care
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front
of the vehicle. Make sure to and extend the mirrors before driving.
●When having your vehicle washed in an automatic car wash, make sure
beforehand that the car wash is of suitable type to avoid scratches to the
vehicle surface and harm to your vehicle’s paint.
●Vehicles with a rear spoiler: In certain automatic car washes, the rear
spoiler may interfere with machine operation. This may prevent the vehi-
cle from being cleaned properly or result in damage to the rear spoiler.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity
of the windows and door frames as water may enter the cabin.
●Before car wash, check that the fuel filler lid on your vehicle is closed
properly.
■Aluminum wheels (if equipped)
●Remove any dirt immediately by using a neutral detergent. Do not use
hard brushes or abrasive cleaners. Do not use strong or harsh chemical
cleaners. Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Parts containing resin such as the bumper
Do not scrub with abrasive cleaners.

WARNING
■When washing the vehicle
●Do not wash the engine compartment and area adjacent to it. If water
enters the engine air intake or electrical parts it will cause engine trouble or
a malfunction of the power steering.
●When washing the vehicle, the brakes may get wet. As a result, the brake
stopping distance will be longer. To dry the brakes, drive the vehicle at a
safe speed while lightly depressing the brake pedal to heat up the brakes.
■Precautions regarding the exhaust pipes
Exhaust gasses cause the exhaust pipes and rear bumper diffusers to
become quite hot.
When washing the vehicle, be careful not to touch the pipes and diffusers
until they have cooled sufficiently, as touching hot exhaust pipes and rear
bumper diffusers can cause burns.
CAUTION
■To prevent paint deterioration and corrosion on the body and compo-
nents (aluminum wheels etc.)
●Wash the vehicle immediately in the following cases:

Maintenance and care
Installing tire pressure warning valves and transmitters (vehicles
with a tire pressure monitoring system)When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and tire
pressure monitoring system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your SUBARU
dealer. ( →P. 314)

4-3. Do-it-yourself maintenance
Registering ID codes (vehicles with a tire pressure monitoring
system)
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your SUBARU dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your SUBARU dealer.
■Replacing tires and wheels (vehicles with a tire pressure monitor-
ing system)
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure monitoring system will not work properly.
After driving for about 20 minutes, the tire pressure warning light comes
on after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Low profile tires (vehicles with 17-inch tires)
Generally, low profile tires will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.

Maintenance and care
■Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
■Tire types
1Summer tiresSummer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3 Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( →P. 229)
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. (
→P. 432)

CAUTION
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure moni-
toring system)
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your SUBARU dealer as the tire pres-
sure warning valves and transmitters may be damaged if not handled
correctly.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmit-
ters (vehicles with a tire pressure monitoring system)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your SUBARU dealer or other qualified service shop as
soon as possible. Make sure to replace the tire pressure warning valve
and transmitter when replacing the tire. (→P. 313)
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition, driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
