Starting and Stopping Engine
230When the warm-up is completed, the
engine speed lowers automatically.
On rare occasions, it may be difficult
to start the engine depending on the
fuel and the usage condition (repeated
driving of a distance in which the
engine has not warmed up suffi-
ciently). In such a case, it is recom-
mended that you change to a different
brand of fuel.
 On rare occasions, transient
knocking may be heard from the
engine when the accelerator is oper-
ated rapidly such as a rapid start-up
and a rapid acceleration. This is not a
malfunction.
 The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.■

Power Steering
243
Starting and Operating7
7-9. Power SteeringPower steering warning lightThe vehicle is equipped with an electric
power steering system. When the ignition
switch is turned to the “ON” position, the
power steering warning light on the combi-
nation meter illuminates to inform the
driver that the warning system is func-
tioning properly. Then, if the engine
started, the warning light turns off to
inform the driver that the steering power
assist is operational.
NOTEIf the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent
the system components, such as the
control computer and drive motor,
from overheating.
 The steering wheel is operated
frequently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently
turning the steering wheel during
parallel parking.
 The steering wheel remains in the
fully turned position for a long period
of time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering
wheel is not operated for a while and the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes
power assist limitation to occur too
frequently, this may result in a mal-
function of the power steering control
system.
702778
CAUTION
While the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.

Vehicle Stability Control (VSC)/TRAC System
248
NOTEThe Vehicle Stability Control (VSC)
system and TRAC system may be con-
sidered normal when the following
conditions occur.
Slight twitching of the brake pedal is
felt.
WARNING
 Directional control and power
may not be achievable while
driving on slippery road surfaces,
even if the TRAC system is oper-
ating. Do not drive the vehicle in
conditions where stability and
power may be lost.Always use the utmost care in
driving – overconfidence
because you are driving with a
Vehicle Stability Control (VSC)
system and TRAC system
equipped vehicle could easily
lead to a serious accident.
CAUTION
Even if your vehicle is equipped
with Vehicle Stability Control
(VSC) system and TRAC system,
winter tires should be used when
driving on snow-covered or icy
roads; in addition, vehicle speed
should be reduced considerably.
Simply having a Vehicle Stability
Control (VSC) system and TRAC
system does not guarantee that
the vehicle will be able to avoid
accidents in any situation.
Activation of the Vehicle Stability
Control (VSC) system and TRAC
system is an indication that the
road being travelled on has a slip-
pery surface; since having
Vehicle Stability Control (VSC)
and TRAC is no guarantee that
full vehicle control will be main-
tained at all times and under all
conditions, its activation should
be seen as a sign that the speed
of the vehicle should be reduced
considerably. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle equipped with the Vehicle
Stability Control (VSC) system
and TRAC system, have an
inspection of that system
performed by an authorized
SUBARU dealer. The following precautions should
be observed in order to ensure
that the Vehicle Stability Control
(VSC) system and TRAC system
is operating properly.
- All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all four
tires.- Keep the tire pressure at theproper level as shown on the
label attached to the driver’s
side center pillar.- When replacing a flat tire, useonly the specified temporary
spare tire. However, even with
the specified temporary spare
tire, the effectiveness of the
Vehicle Stability Control (VSC)
system and TRAC system will
be reduced.
If non-matching tires are used,
the Vehicle Stability Control
(VSC) system and TRAC system
may not operate correctly.

Using a Flat-Bed Truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the select lever into the “P” posi-
tion for AT models. Shift the shift lever into
the “1st” position for MT models.
2. Apply the parking brake firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.

Towing with All Wheels on
the Ground
WARNING
Use the rear tie-down holes only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip out
of the holes, possibly causing a
dangerous situation.
900488
CAUTION
Transport by flat-bed truck may
cause the headlights to become
misaligned. In such a case, have the
headlight alignment checked by a
SUBARU dealer after transporting
the vehicle by flat-bed truck.
WARNING
 Never turn the ignition switch to
the “OFF” position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked.Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it w ill take greater
effort to operate the brake pedal
and steering wheel.

Exterior Care
33210-1. Exterior Care■
WashingNOTE
When having your vehicle washed in
an automatic car wash, make sure
beforehand that the car wash is of
suitable type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the
vehicle at least once a month to avoid
contamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash
the vehicle with hot water and in direct
sunlight.
Salt, chemicals, insects, tar, soot, tree
sap, and bird droppings should be washed
off by using a light detergent, as required.
If you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly
flushed from the surface and not allowed
to dry there. Rinse the vehicle thoroughly with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft
cloth. Wear rubber gloves and use a hand
brush when washing down underbody,
inner fenders and suspension to effec-
tively remove mud and dirt off.
▼
Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely corro-
sive, accelerating the corrosion of under-
body components, such as the exhaust
system, fuel and brake lines, brake
cables, floor pan and fenders, and
suspension.
Thoroughly flush the underbody and
inside of the fenders with lukewarm or
cold water at frequent intervals to reduce
the harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or
sandy roads, wash the mud and sand off
the underbody.
Carefully flush the suspension and axle
parts, as they are particularly prone to
mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
CAUTION
 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 pressing the brake
pedal to heat up the brakes.Do not wash the engine compart-
ment and areas 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 inner fenders,
underbody, bumpers and
protruding objects such as
exhaust pipes and exhaust
finishers, be careful to prevent
injuries from contacting sharp
ends.
Do not use any organic solvents
when washing the surface of the
bulb assembly cover. However, if
a detergent with organic solvents
is used to wash the cover surface,
completely rinse off the detergent
with water. Otherwise, the cover
surface may be damaged.

Tire Information

Consumer Information and Reporting Safety Defects13
– CONTINUED –
The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-
mation.
▼Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp
increase in temperature could
cause tread separation, and failure
of the tire(s). Possible resulting loss
of vehicle control could lead to an
accident.
▼ Measuring and adjusting air
pressure to achieve proper
inflation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to adjust the tire pressures to the
specific values. 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 vehicle. When a tire
becomes warm, t
he 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.
■ Glossary of Tire TerminologyAccessory weight
The combined weight (in excess of
those standard items which may be
replaced) of automatic transmis-
sion, power steering, power brakes,
power windows, power seats, radio,
and heater, to the extent that these
items are available as factory-
installed equipment (whether
installed or not).
 Bead
The part of the tire that is made of
steel wires, wrapped or reinforced by ply cords and that is shaped to fit
the rim.

Bead separation
A breakdown of the bond between
components in the bead.
 Bias ply tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at alternate an gles substantially
less than 90 degrees to the
centerline of the tread.
 Carcass
The tire structure, except tread and
sidewall rubber which, when
inflated, bears the load.
 Chunking
The breaking away of pieces of the
tread or sidewall.
 Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more.
 Cord
The strands forming the plies in the
tire.
