Driving tips
when towing a trailer and you should never
speed. You should also keep the following tips
in mind:
T Before starting out on a trip
y Check that the vehicle and vehicle-to-hitch mount-
ing are in good condition. If any problems are appar-
ent, do not tow the trailer. y Check that the vehicle sits horizontally with the trail-
er 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 con-
firm that the load and its distribution are acceptable.y Check that the tire pressures are correct.
y 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 vehi-
cle’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.
y 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 traffic, practice turning, stopping
and backing up. T Driving with a trailer
y You should allow for considerably more stopping
distance when towing a trailer. Avoid sudden braking
because it may result in skidding or jackknifing and
loss of control. y Avoid abrupt starts and sudden accelerations. If
your vehicle has a manual transmission, always start
out in first gear and release the clutch at moderate en-
gine revolution. y Avoid uneven steering, sharp turns and rapid lane
changes. y Slow down before turning. Make a longer than nor-
mal turning radius because the trailer wheels will be
closer than the vehicle wheels to the inside of the turn.
In a tight turn, the trailer could hit your vehicle. y Crosswinds will adversely affect the handling of
your vehicle and trailer, causing sway. Crosswinds
can be due to weather conditions or the passing of
large tracks or buses. If swaying occurs, firmly grip the
steering wheel and slow down immediately but gradu-
ally. y When passing other vehicles, considerable dis-

Temporary spare tire
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 cor-
rect pressure is 60 psi (420 kPa, 4.2 kg/cm 2
).
When using the temporary spare tire, note the follow-
ing: y Do not exceed 50 mph (80 km/h).
y Do not put a tire chain on the temporary spare tire.
Because of the smaller tire size, a tire chain will not fit
properly. y Do not use two or more temporary spare tires at the
same time. y Do not drive over obstacles. This tire has a smaller
diameter, so road clearance is reduced. 1) Tread wear indicator bar
2) Indicator location mark
y When the wear indicator appears on the tread, re-
place the tire.

not pressed against the curb when you park the
vehicle.y
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 wheels may be damaged. Drive
slowly to the nearest authorized SUBARU dealer
and have the vehicle inspected. „ Tire pressures and wear
Maintaining the correct tire pressures helps to maxi-
mize the tires’ service lives and is essential for good
running performance. Check and, if necessary, adjust
the pressure of each tire (including the spare) at least
once a month (for example, during a fuel stop) and be-
fore any long journey. 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 lo-
cated on the door pillar on the driver’s side.
Driving even a short distance warms up the tires and
increases the tire pressures. Also, the tire pressures
are affected by the outside temperature. It is best to
check tire pressure outdoors before driving the vehi- cle.
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 itspressure.

NOTE yThe air pressure in a tire increases by approxi-
mately 4.3 psi (30 kPa, 0.3 kgf/cm 2
) when the tire
becomes warm. y 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).
Do not let air out of warm tires to adjust pres-
sure. Doing so will result in low tire pressure.
Incorrect tire pressures detract from controllability and
ride comfort, and they cause the tires to wear abnor-
mally. y
Correct tire pressure (tread worn evenly)
Roadholding is good, and steering is responsive. Roll-
ing resistance is low, so fuel consumption is also low-er.

y
Abnormally low tire pressure (tread worn at
shoulders)
Rolling resistance is high, so fuel consumption is also
higher. y
Abnormally high tire pressure (tread worn in cen-
ter)
Ride comfort is poor. Also, the tire magnifies the ef-
fects of road-surface bumps and dips, possibly result-
ing 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.
Driving at high speeds with excessively low tire
pressures can cause the tires to deform severe-

*1: The recommended cold tire pressure for the 215/45R17 87W tire is not indicated on the vehicle placard attached to the drive r’s
side B-pillar since this tire is a dealer option for the WRX. If your vehicle is equipped with 215/45R17 87W tires, be sure to adjust
them to the air pressure shown on this page.
