Instruments and controls
The key can be turned from “ACC” to “LOCK” only
when the selector lever is in the “P” position. T
Manual transmission vehicles
The key can be turned from “ACC” to “LOCK” only
when the key is pushed in while turning it.
y Never turn the ignition switch to “LOCK”
while the vehicle is being driven or towed be-
cause that will lock the steering wheel, prevent-
ing steering control. And when the engine is
turned off, it takes a much greater effort than usual to steer.y
Before leaving the vehicle, always remove
the key from the ignition switch for safety and
never allow an unattended child to remain in
the vehicle. Failure to follow this procedure
could result in injury to a child or others. They
could operate the power windows, the sunroof
or other controls or even make the vehicle
move.
„ ACC
In this position the electrical accessories (radio, ciga-
rette lighter, etc.) can be used. „ ON
This is the normal operating position after the engine
is started. „ START
The engine is started in this position. The starter
cranks the engine to start it. When the key is released
(after the engine has started), the key automatically
returns to the “ON” position.

celerator pedal.
3) If this fails to start the engine, turn the ignition
switch again to the “OFF” position. After waiting for
10 seconds or longer, turn the ignition switch to the
“START” position without depressing the accelera-
tor pedal.
4) If the engine still refuses to start, contact your
nearest SUBARU dealer for assistance.
6. Confirm that all warning and indicator lights have
gone out after the engine has started. The fuel injec-
tion system automatically lowers the idle speed as the
engine warms up.
While the engine is warming up, make sure that the
selector lever is at the “P” or “N” position and that the
parking brake is applied.
If you restart the engine while the vehicle is
moving, shift the selector lever into the “N” po-sition. Do not attempt to place the selector lever
of a moving vehicle into the “P” position.
Stopping the engine
The ignition switch should be turned off only when the
engine is idling.
Do not stop the engine when the vehicle is mov-
ing. This will cause loss of power to the power
steering and the brake booster, making steer-
ing and braking more difficult. It could also re-
sult in accidental activation of the “LOCK” po-
sition on the ignition switch, causing the steer-
ing wheel to lock.

4. Insert the screwdriver into the hole.
5. Push down on the screwdriver and move the selec-
tor lever from the “P” to the “N” position.
6. Remove the screwdriver from the hole. Depress
the brake pedal and start the engine.
Take your vehicle to the nearest SUBARU dealer im-
mediately to have the system repaired.
Limited slip differential (LSD) (if
equipped)
The LSD provides optimum distribution of power ac-
cording to the difference in revolutions between the
right and left wheels that may be caused by certain
driving conditions, thereby improving driving stability
on snow-covered, muddy or other slippery roads or
when high speed driving.
NOTE (WRX-STi)
The rear differential may emit a knocking sound
when the vehicle is driven slowly with the steering wheel turned fully to either side. This sound oc-
curs because of the design of the mechanical LSD.
It does not indicate a problem.
y
Never start the engine while a tire on one side
is jacked up, as the vehicle may move. y If one tire is spinning in mud, avoid continued
spinning at high speed as this could adversely
affect the LSD. y If you use a temporary spare tire to replace a
flat tire, be sure to use the original temporary
spare tire stored in the vehicle. Using other siz-

es will adversely affect the LSD.Power steering
The power steering system operates only when the
engine is running.
If you lose power steering assist because the engine
stops or the system fails to function, you can steer but
it will take much more effort.
NOTE
Right after the engine has been started and before
it has warmed up, you may hear a noise coming
from areas adjacent to the power steering pump
which is located at the right-front area of the en-
gine compartment. This noise is normal. It does
not indicate power steering system trouble.
Do not hold the steering wheel at the fully
locked position left or right for more than five
seconds. This may damage the power steering
pump.

In case of emergency

„Towing with all wheels on the ground
1. Check the transmission and differential oil levels
and add oil to bring it to the upper level if necessary.
2. Release the parking brake and put the transmis-
sion in neutral.
3. The ignition switch should be in the “ACC” position
while the vehicle is being towed.
4. Take up slack in the towline slowly to prevent dam-
age to the vehicle.
y Never turn the ignition switch to the “LOCK”
position while the vehicle is being towed be- cause the steering wheel and the direction of
the wheels will be locked.y
Remember that the brake booster and power
steering do not function when the engine is not
running. Because the engine is turned off, it will
take greater effort to operate the brake pedal
and steering wheel.
y If transmission failure occurs, transport your
vehicle on a flat-bed track. y Do not run the engine while being towed us-
ing this method. Transmission damage could
result if the vehicle is towed with the engine
running. y For vehicles with automatic transmission,
the traveling speed must be limited to less than
20 mph (30 km/h) and the traveling distance to
less than 31 miles (50 km). For greater speeds
and distances, transport your vehicle on a flat-
bed track.

Washing
The best way to preserve your vehicle’s beauty is fre-
quent 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 luke-
warm or cold water. Do not wash the vehicle with hot
water and in direct sunlight.
Salt, chemicals, insects, tar, soot and bird droppings
should be washed off by using a light detergent, as re-
quired. 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.
NOTE
When having your vehicle washed in an automatic
car wash, make sure beforehand that the car wash
is of suitable type. Automatic car wash brushes or
other equipment may damage the rear wiper and
rear/roof spoiler (if equipped).
y When washing the vehicle, the brakes may
get wet. As a result, the brake stopping dis-
tance 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. y Do not wash the engine compartment and
area adjacent to it. If water enters the engine air
intake, electrical parts or the power steering flu-
id reservoir, it will cause engine trouble or
faulty power steering respectively.
T Washing the underbody
Chemicals, salts and gravel used for deicing road sur-
faces are extremely corrosive, accelerating the corro-
sion of underbody 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 inter-
vals to reduce the harmful effects of such agents.
Mud and sand adhering to the underbody components may accelerate their corrosion.
After driving off-road or on muddy or sandy roads,
wash the mud and sand off the underbody. Carefully
