8-36Connection of trailer lights to your vehicle
’s electrical system requires
modifications to the vehicle ’s lighting circuit to increase its capacity
and accommodate wiring changes. To ensure the trailer lights are
connected properly, please consult your SUBARU dealer. Check for
proper operation of the turn signals, the brake lights and parkinglights each time you hitch up. n Tires
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load.
Use of the temporary spare tire when towing can result in failureof the spare tire and/or less stability of the vehicle.
Make sure that all the tires on your vehicle are properly inflated. OUTBACK: The recommended cold tire pressure under trailer
towing conditions is indicated on the tire placard located under thedoor striker on the driver ’s side. Adjust the rear tire pressure to the
recommended pressure shown on the tire placard when the tires
are cold. Normal pressure should be maintained in the front tires.Other models: It is recommended to inflate the rear tires to 3 psi
(20 kPa, 0.2 kg/cm 2
) above their normal operating pressure when
the tires are cold. Normal pressure should be maintained in the
front tires.
Trailer tire condition, size, load rating and proper inflation pressure
should be in accordance with the trailer manufacturer ’s specifications.
In the event your vehicle gets a flat tire when towing a trailer, ask a
commercial road service to repair the flat tire.
If you carry a regular size spare tire in your vehicle or trailer as a pre-
caution against getting a flat tire, be sure that the spare tire is firmly
secured.

Temporary spare tire
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load.
Use of the temporary spare tire when towing can result in failureof the spare tire and/or less stability of the vehicle and may leadto an accident.
CAUTION
Never use any temporary spare tire other than the original. Usingother sizes may result in severe mechanical damage to the drivetrain of your vehicle.
The temporary spare tire is smaller and lighter than a conventional tire
and is designed for emergency use only. Remove the temporary spare
tire and re-install the conventional tire as soon as possible because the
spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare tire periodically to
keep the tire ready for use. The correct pressure is 60 psi (420 kPa, 4.2
kg/cm 2
).
When using the temporary spare tire, note the following: Do not exceed 50 mph (80 km/h).
Do not put a tire chain on the temporary spare tire. Because of the
smaller tire size, a tire chain will not fit properly. Do not use two or more temporary spare tires at the same time.
Do not drive over obstacles. This tire has a smaller diameter, so
road clearance is reduced. When the wear indicator appears on the tread, replace the tire.

NOTE
[Automatic transmission vehicle not equipped with VDC (Vehicle Dy-
namics Control) and not equipped with SPORTSHIFT] Before drivingyour vehicle with the temporary spare tire, put a spare fuse insidethe FWD connector located in the engine compartment and confirm
that the Front-wheel drive warning light comes on. The all wheeldrive capability of the vehicle has now been deactivated. After re-
installing the conventional tire, remove the spare fuse from the FWDconnector in order to reactivate all wheel drive.
Flat tires
WARNING
Do not jack up the vehicle on an incline or a loose road sur-
face. The jack can come out of the jacking point or sink into the ground and this can result in a severe accident. Use only the jack provided with your vehicle. The jack sup-
plied with the vehicle is designed only for changing a tire. Neverget under the vehicle while supporting the vehicle with this jack. Always turn the engine off before raising the flat tire off the
ground using the jack. Never swing or push the vehicle sup-ported with the jack. The jack can come out of the jacking pointdue to a jolt and this can result in a severe accident.

Tires and wheels Types of tires
You should be familiar with type of tires present on your vehicle.
All season tires
The factory-installed tires on your new vehicle are all season tires.
All season tires are designed to provide an adequate measure of trac-
tion, handling and braking performance in year-round driving includ-
ing snowy and icy road conditions. However all season tires do not
offer as much traction performance as winter (snow) tires in heavy or
loose snow or on icy roads.
All season tires are identified by “ALL SEASON ” and/or “M+S” (Mud &
Snow) on the tire sidewall. Summer tires
Summer tires are high-speed capability tires best suited for highway
driving under dry conditions.
Summer tires are inadequate for driving on slippery roads such as on
snow-covered or icy roads.
If you drive your vehicle on snow-covered or icy roads, we strongly
recommend the use of winter (snow) tires.
When installing winter tires, be sure to replace all four tires.

Winter (snow) tires
Winter tires are best suited for driving on snow-covered and icy
roads. However winter tires do not perform as well as summer tires
and all season tires on roads other than snow-covered and icy roads.
Tire inspection
Check on a daily basis that the tires are free from serious damage, nails,
and stones. At the same time, check the tires for abnormal wear.
Contact your SUBARU dealer immediately if you find any problem. NOTE When the wheels and tires strike curbs or are subjected to harsh
treatment as when the vehicle is driven on a rough surface, they can suffer damage that cannot be seen with the naked eye. This type of
damage does not become evident until time has passed. Try not todrive over curbs, potholes or on other rough surfaces. If doing so is
unavoidable, keep the vehicle ’s speed down to a walking pace or
less, and approach the curbs as squarely as possible. Also, makesure the tires are not pressed against the curb when you park thevehicle. If you feel unusual vibration while driving or find it difficult to
steer the vehicle in a straight line, one of the tires and/or wheelsmay be damaged. Drive slowly to the nearest authorized SUBARUdealer and have the vehicle inspected. Tire pressures and wear
Maintaining the correct tire pressures helps to maximize the tires ’ service
lives and is essential for good running performance. Check and, if nec-
essary, adjust the pressure of each tire (including the spare) at least
once a month (for example, during a fuel stop) and before any long jour-
ney.
Check the tire pressures when the tires are cold. Use a pressure gauge
to adjust the tire pressures to the values shown on the tire placard. The
tire placard is located on the door pillar on the driver ’s side.

11-40
HB0382
Driving even a short distance warms up the tires and increases the tire
pressures. Also, the tire pressures are affected by the ambient tempera-
ture. It is best to check tire pressure outdoors before driving the vehicle.
When a tire becomes warm, the air inside it expands, causing the tire
pressure to increase. Be careful not to mistakenly release air from a
warm tire to reduce its pressure. NOTE The air pressure in a tire increases by approximately 4.3 psi (30
kPa, 0.3 kg/cm 2
) when the tire becomes warm.
The tires are considered cold when the vehicle has been parked
for at least three hours or has been driven less than one mile (1.6 km).
WARNING
Do not let air out of warm tires to adjust pressure. Doing so willresult in low tire pressure.
Incorrect tire pressures detract from controllability and ride comfort, and
they cause the tires to wear abnormally.

11-42
Abnormally high tire pressure (tread worn in center)
HSB013AA
Ride comfort is poor. Also, the tire magnifies the effects of road-sur-
face bumps and dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for the vehicle when fully loaded
and for the vehicle when towing a trailer, adjust the tire pressures to the
values that match current loading conditions.
WARNING
Driving at high speeds with excessively low tire pressures can
cause the tires to deform severely and to rapidly become hot. Asharp increase in temperature could cause tread separation, and
destruction of the tires. The resulting loss of vehicle controlcould lead to an accident.
Wheel balance
Each wheel was correctly balanced when your vehicle was new, but the
wheels will become unbalanced as the tires become worn during use.
Wheel imbalance causes the steering wheel to vibrate slightly at certain
vehicle speeds and detracts from the vehicle ’s straight-line stability. It
can also cause steering and suspension system problems and abnormal
tire wear. If you suspect that the wheels are not correctly balanced, have
them checked and adjusted by your SUBARU dealer. Also have them
adjusted after tire repairs and after tire rotation.
