Trailer towing tips CAUTION
Never exceed 45 mph (72 km/h) when towing a trailer in hilly
country on hot days. When towing a trailer, steering, stability, stopping distance and
braking performance will be different from normal operation. For
safety’ s sake, you should employ extra caution when towing a
trailer and you should never speed. You should also keep the fol-lowing tips in mind:
n Before starting out on a trip
Check that the vehicle and vehicle-to-hitch mounting are in good
condition. If any problems are apparent, do not tow the trailer. Check that the vehicle sits horizontally with the trailer attached. If
the vehicle is tipped sharply up at the front and down at the rear,
check the total trailer weight, GVW, GAWs and tongue load again,
then confirm that the load and its distribution are acceptable. Check that the tire pressures are correct.
Check that the vehicle and trailer are connected properly. Confirm
that. –the trailer tongue is connected properly to the hitch ball.
– the trailer lights connector is connected properly and trailer ’s
brake lights illuminate when the vehicle ’s brake pedal is pressed,
and that the trailer ’s turn signal lights flash when the vehicle ’s turn
signal lever is operated.– the safety chains are connected properly.
– all cargo in the trailer is secured safety in position.
– the side mirrors provide a good rearward field of view without a
significant blind spot.
Sufficient time should be taken to learn the “feel” of the vehicle/
trailer combination before starting out on a trip. In an area free of traf-
fic, practice turning, stopping and backing up.

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.

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.

Correct tire pressure (tread worn evenly)
HGB033AA
Roadholding is good, and steering is responsive. Rolling resistance is
low, so fuel consumption is also lower.
Abnormally low tire pressure (tread worn at shoulders)
HSB012AA
Rolling resistance is high, so fuel consumption is also higher.

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.

11-44
Tire rotation
OM-H0230
Tire wear varies from wheel to wheel. To maximize the life of each tire
and ensure that the tires wear uniformly, it is best to rotate the tires every
7,500 miles (12,500 km). Rotating the tires involves switching the front
and rear tires on the right-hand side of the vehicle and similarly switching
the front and rear tires on the left-hand side of the vehicle. (Each tiremust be kept on its original side of the vehicle.)
Replace any damaged or unevenly worn tire at the time of rotation. After
tire rotation, adjust the tire pressures and make sure the wheel nuts are
correctly tightened.
After driving approximately 600 miles (1,000 km), check the wheel nuts
again and retighten any nut that has become loose. Tire replacement
The wheels and tires are important and integral parts of your vehicle ’s
design; they cannot be changed arbitrarily. The tires fitted as standard
equipment are optimally matched to the characteristics of the vehicle
and were selected to give the best possible combination of running per-
formance, ride comfort, and service life. It is essential for every tire to
have a size and construction matching those shown on the tire placard
and to have a speed symbol and load index matching those shown on
the tire placard.
Using tires of a non-specified size detracts from controllability, ride com-
fort, braking performance, speedometer accuracy and odometer accu-
