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.

Braking
2447-10. Braking■
Braking Tips
▼
When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the
vehicle at a safe speed while lightly
depressing the brake pedal to heat up the
brakes.
▼Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When
descending a grade, if only the foot brake
is used, the brakes may start working
improperly because of brake fluid over-
heating, caused by overheated brake
pads. To help prevent this, shift into a
lower gear to get stronger engine braking. ▼
Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause
a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.
■
Brake System
▼
Two separate circuits
Your vehicle has a dual circuit brake
system. Each circuit works diagonally
across the vehicle. If one circuit of the
brake system should fa il, the other half of
the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
▼Brake booster
The brake booster uses vacuum pump
system to assist braki ng force. Do not turn
off the engine while driving because that
will turn off the brake booster, resulting in
poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to depress the pedal much harder than normal and the braking
distance will increase.
▼
Supplemental booster function
when vacuum pressure fails
While the ignition switch is turned “ON”
and the engine is running, the supple-
mental booster function operates when
the brake booster performance is
decreased due to insufficient vacuum
boost.
When the brake pedal is depressed while
the supplemental booster function is oper-
ating, an operation sound and brake pedal
vibration may be generated. This is not a
malfunction.
▼Brake assist system
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads.
WARNING
Do not be overco nfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.

Flat Tires
308Do not use tire chains on a sealed
tire.Do not tow a trailer.If used for a purpose other than
sealing a flat tire, the flat tire
repair kit may cause a severe
accident or injury due to the fact
that compressed air can act as an
explosive or propellant.Safely park your vehicle on the
roadside so that you do not
obstruct the flow of traffic and so
that you are able to seal the flat
tire without being in danger.Apply the parking brake, even if
the vehicle is parked on a level
road, to make sure that the
vehicle will not move.Stop the engine before sealing
the flat tire.Turn on the hazard warning
flasher while sealing the flat tire.Do not attempt to remove foreign
objects like nails or screws that
have penetrated the tire. Leave
them as they are. Never leave the flat tire repair kit
unattended while in use.Only one tire can be repaired with
one bottle of sealant.
The tires can be repaired when
the ambient temperature is −22 °F
( − 30 °C) or higher.
CAUTION
 Remember that the flat tire repair
kit only provides temporary
mobility. Regulations concerning
tire repair after usage of flat tire
repair kit may di ffer from country
to country. We recommend that
you consult your SUBARU dealer
or tire dealer for advice. Store the flat tire repair kit safely
and secure it under the floor of
the trunk. Storing it anywhere in
the passenger compartment is
not advisable because it could
strike an occupant in the event of
a sudden stop or collision and
cause injury. Use the flat tire repair kit with
original vehicle tires only.Do not keep the air compressor
operating for more than 10
minutes, otherwise there is a risk
of overheating.The temperature of the air
compressor may become high.
Be careful not to burn yourself.
When raining, take measures to
prevent the air compressor from
being exposed directly to the
rain. Exposing to rain may cause
a malfunction.Do not use air compressors other
than the one in the repair kit.
Using an air compressor other
than the one in the repair kit may
damage the tires.Do not disassemble or modify the
air compressor to enable the use
of a power supply or a battery
other than DC 12 V.If a temporary puncture repair is
performed with the repair kit, the
Tire Pressure Monitoring System
(TPMS) (if equipped) may not
operate normally.

Engine Overheating
319
In Case of Emergency9
9-5. Engine Overheating■
If Steam Is Coming from the
Engine Compartment
Turn off the engine and get everyone
away from the vehicle until it cools down.
■
If No Steam Is Coming from
the Engine Compartment
1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment. Refer to "Engine Hood"
P343.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the over-
heated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the “LOW”
mark, add coolant up to the “FULL” mark.NOTEFor details about how to check the
coolant level or how to add coolant,
refer to "Eng ine Coolant" 
P349.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the radiator cap, then turn the cap
counterclockwise slowly without pressing
down until it stops. Release the pressure
from the radiator. After the pressure has
been fully released, remove the cap by
pressing down and turning it.
WARNING
Never remove the radiator cap until
the engine has been shut off and
has fully cooled down. When the
engine is hot, the coolant is under
pressure. Removing the cap while
the engine is still hot could release
a spray of boiling hot coolant,
which could burn you very seri-
ously.
CAUTION
If the engine overheats, the engine
speed or the vehicle speed may be
reduced. Stop the vehicle in a safe
place immediately.
