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.

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.

does not have a Vehicle Stability
Control (VSC) system and TRAC
system. Do not deactivate the Vehicle
Stability Control (VSC) system and
TRAC system except when absolutely
necessary. 
Even when the TRAC system is
deactivated, compon ents of the brake
control system may still activate. When
the brake control system is activated,
the Vehicle Stability Control (VSC)
operation indicator light flashes.

TRACK Mode
Your vehicle is equipped with two types of
control modes to accommodate various
driving preferences. The control modes
can be selected with the TRACK switch.
Normal mode allows secure and smooth
normal driving. When the switch is
pressed and held for 1 second or more,
TRACK mode is activated. Control char-
acteristics such as the Vehicle Stability
Control (VSC) and TRAC are adjusted to
afford maneuverability closer to what a
driver may desire, while a sense of secu-
rity is retained.

 If you accidentally press the TPMS set
switch when initializa tion is not necessary,
adjust the tire inflation pressure to the
specified level when the tires are cold, and
conduct initialization again.
■
When Initialization of the Tire
Pressure Monitoring System
has Failed
Initialization can be completed in a few
minutes. However, in the following case,
the settings have not been recorded and
the system will not operate properly. If
repeated attempts to record tire inflation
pressure settings are unsuccessful, have
the vehicle checked at your SUBARU
dealer.
 When operating the TPMS set switch,
low tire pressure warning light does not
blink 3 times.
 After carrying out the initialization
procedure, the low tire pressure warning
light blinks for 1 minute then stays on after
driving for 20 minutes.
■
Registering ID Codes
Every tire pressure warning valve and
transmitter has a unique ID code. In addi-
tion to the set of tire pressure warning
system sensor ID code s initially registered
to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning
system sensor ID codes can be registered
at your SUBARU dealer. When 2 sets of
ID codes have been registered, either ID
code set can be selected.■
Changing the ID code set
1. Park the vehicle in a safe place and
turn the ignition switch to the “ON” posi-
tion.
2. Press the TPMS set switch 3 times
within 3 seconds.
3. The low tire pressure warning light will
illuminate for 3 seconds and then blink 3
times.
4. The low tire pressure warning light will
blink for 1 minute and then illuminate.
5. When the ID code change has
completed, the tire pressure monitoring
light will turn off.
Check that tire pressures are displayed on
the TPMS screen.
WARNING
Do not operate the TPMS set switch
without first adjusting the tire infla-
tion pressure to the specified level.
Otherwise, the low tire pressure
warning light may not come on even
if the tire inflation pressure is low,
or it may come on when the tire
inflation pressure is actually nor-
mal.

Hill Start Assist System
258In both these cases, the Hill start assist
system operates under the following
conditions.
 The clutch pedal is depressed while the
brake pedal is also depressed (MT
models).
 The vehicle has stopped with the brake
pedal depressed (AT models).
Braking power is maintained temporarily
(for approximately 2 seconds) by the Hill
start assist system after the brake pedal is
released. The driver is therefore able to
start the vehicle in the same way as on a
level grade, just using the clutch pedal
(MT models only) and accelerator pedal
(all models).
If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.
The Hill start assist system may not
operate on slight grades. Also, the Hill
start assist system does not operate in the
following cases.
When starting backward facing uphill
 When starting forward facing downhill
 While the parking brake is applied
 While the ignition switch is in the “ACC”
or “OFF” position 
While the Hill start assist indicator light
is illuminated. Refer to "Hill Start Assist
Indicator Light" P150.
When using the Hill start assist system, a
braking effect may be felt even after the
brake pedal has been released. However,
for MT models, this braking effect should
disappear once the clutch pedal is
released.
NOTEA slight jolt may be felt when the vehi-
cle begins to move forward after being
reversed.

CAUTION
The braking power of the Hill start
assist system may not be sufficient
when strong braking power is
needed (e.g., when towing a trailer).
