road with a snowy, gravel-covered, or
otherwise slippery surface .extrication of the vehicle when its
wheels are stuck in mud or deep snow
When the switch is pressed during engine
operation, the Vehicle Dynamics Control
OFF indicator light on the combination
meter illuminates. The Vehicle Dynamics
Control system will be deactivated and the
vehicle will behave like a model not
equipped with the Vehicle Dynamics Con-
trol system. When the switch is pressed
again to reactivate the Vehicle Dynamics
Control system, the Vehicle Dynamics
Control OFF indicator light turns off.
With the Vehicle Dynamics Control system
deactivated, traction and stability en-
hancement offered by Vehicle Dynamics
Control system is unavailable. Therefore
you should not deactivate the Vehicle
Dynamics Control system except under
above-mentioned situations. NOTE . The Vehicle Dynamics Control sys-
tem will be activated automatically
when the engine is started.. If the switch is held down for 10
seconds or longer, the indicator light
turns off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the switch. To make the switch usable
again, turn the ignition switch to the“
LOCK ”position and restart the en-
gine.. When the switch is pressed to
deactivate the Vehicle Dynamics Con-
trol system, the vehicle ’s running per-
formance is comparable with that of a
vehicle that does not have a Vehicle
Dynamics Control system. Do not de-
activate the Vehicle Dynamics Control
system except when absolutely neces-
sary.. Even when the Vehicle Dynamics
Control system is deactivated, compo-
nents of the brake control system may
still activate. When the brake control
system is activated, the Vehicle Dy-
namics Control operation indicator
light illuminates. Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)
Turbo models
Non-turbo models

The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also,
this system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a
sharp object).
WARNING
If the low tire pressure warning light
illuminates while driving, never
brake suddenly and keep driving
straight ahead while gradually redu-
cing speed. Then slowly pull off the
road to a safe place. Otherwise an
accident involving serious vehicle
damage and serious personal injury
could occur.
Check the pressure for all four tires
and adjust the pressure to the COLD
tire pressure shown on the tire
placard on the door pillar on thedriver ’s side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures increase accordingly. Be sure to let the tires
cool thoroughly before adjusting
their pressures to the standard
values shown on the tire placard.
Refer to
“Tires and wheels ”F 11-31.
The tire pressure monitoring system
does not function when the vehicle
is stationary. After adjusting the tire
pressures, increase the vehicle
speed to at least 20 mph (32 km/h)
to start the TPMS re-checking of the
tire inflation pressures. If the tire
pressures are now above the severe
low pressure threshold, the low tire
pressure warning light should turn
off a few minutes later.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors. If the light
illuminates steadily after blinking for
approximately one minute, promptly
contact a SUBARU dealer to have
the system inspected.CAUTION
. Do not place metal film or any
metal parts in the cargo area/
trunk. This may cause poor re-
ception of the signals from the
tire pressure sensors, and the
tire pressure monitoring system
will not function properly.

the parking brake lever is fully pulled up.
To release the parking brake, pull the lever
up slightly, press the release button, then
lower the lever while keeping the button pressed.
When the parking brake is set while the
engine is running, the parking brake
warning light illuminates. After starting
the vehicle, be sure that the warning light
has turned off before the vehicle is driven.
Refer to “Parking brake warning ”F 3-21.
CAUTION
Never drive while the parking brake
is set because this will cause un-
necessary wear on the brake lin-
ings. Before starting to drive, always
make sure that the parking brake
has been fully released.
& Parking tips
When parking your vehicle, always per-
form the following items. . Apply the parking brake firmly.
. For MT models, put the shift lever in the
“ 1 ” (1st) for upgrade or “R ”(Reverse) for a
downgrade.. For AT models, put the select lever in
the “P ”(Park) position.
Never rely on the transmission alone to
hold the vehicle.

When parking on a hill, always turn the
steering wheel. When the vehicle is
headed up the hill, the front wheels should
be turned away from the curb.
When facing downhill, the front wheels
should be turned into the curb.
WARNING
. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), pay attention to blocks and other obstructions on the
ground when parking. The under-
spoilers could be damaged by con-
tact with them.

Hill start assist system (MT models –if equipped)
CAUTION
The Hill start assist system is a
device only for helping the driver
to START the vehicle on an uphill
grade. To prevent accidents when
the vehicle is parked on a slope, be
sure to firmly set the parking brake.
When setting the parking brake,
make sure that the vehicle remains
stationary when the clutch pedal isreleased.
The Hill start assist system is a device to
make starting on an uphill grade easier.
On an uphill grade, when the clutch pedal
is depressed while the brake pedal is also
depressed, braking power is maintained
temporarily by the Hill start assist system
when the brake pedal is released. The
driver is therefore able to start the vehicle
the same way as on a level grade, just
using the clutch and accelerator pedal.
The Hill start assist system does not
operate when the vehicle is facing down-
hill. And the Hill start assist system may
not operate on slight grades.
When starting in reverse and using the Hill
start assist system, a braking effect may
be felt even after the brake pedal has
been released. However, this braking
effect should disappear once the clutch
pedal is released. A slight jolt may be felt when the vehicle
begins to move forward after being re-versed.
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. &
To activate/deactivate the Hill
start assist system (STI)
CAUTION
While the Hill start assist system is
deactivated, when starting on an
uphill grade, braking power is not
maintained if the brake pedal is
released. Start on an uphill grade
by using the parking brake.
You can activate/deactivate the Hill start
assist system according to the followingprocedure. ! To deactivate
1. Stop your vehicle in a flat and safe
place and apply the parking brake.

vehicle speed when the button is
pushed and the speed last time you
set is less than 4 mph (6.8 km/h), the
vehicle speed will be lowered by 1 mph
(1.6 km/h). This occurs because the
cruise control system unit regards this
operation as that intended to decrease
the vehicle speed. !
To decrease the speed (by button)
Push the “SET/COAST ”button and hold it
until the vehicle reaches the desired
speed. Then, release the button. The
vehicle speed at that moment will be
memorized and treated as the new setspeed.
