Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
&System monitors
A diagnostic system continually monitors
the readiness of the seatbelt pretensioner
while the vehicle is being driven. The
seatbelt pretensioners share the control
modulewiththeSRSairbagsystem.
Therefore, if any malfunction occurs in a
seatbelt pretensioner, the SRS airbag
system warning light will illuminate. For
details, refer to “SRS airbag system
monitors ”F 1-67.
& System servicing
WARNING
. When discarding a seatbelt re-
tractor assembly or scrapping
the entire vehicle damaged by a
collision, consult your SUBARU
dealer.
. Tampering with or disconnecting
the system’ s wiring could result
in accidental activation of the
seatbelt pretensioner and/or
SRS airbag or could make the
system inoperative, which may
result in serious injury. Do not
use electrical test equipment on
any circuit related to the seatbelt
pretensioner and SRS airbag
systems. For required servicing of the seatbelt pretensioner, con-
sult your nearest SUBARU deal-
er.

NOTE
.After replacing or adding the engine
oil, if the engine oil level is within the
normal range when restarting the en-
gine on a level surface, the warning
light will turn off.
. The warning light may illuminate
temporarily in the following conditions
because a low oil level may be detected
as a result of significant oil movement
in the engine.
–when the vehicle is considerably
inclined on an uphill or steep slope
– when the vehicle has continu-
ously accelerated and decelerated
– when the vehicle is continuously
turned
– when the vehicle is driven on a
road that alternates continuously
between uphill and downhill
&Windshield washer
fluid warning light
This light illuminates when the fluid level in
the windshield washer fluid tank de-
creases to the lower limit (approximately
1.1 US qt, 1.0 liter, 0.9 Imp qt).
&AT OIL TEMP warning
light (CVT models)
If this light illuminates when the engine is
running, it may indicate that the transmis-
sion fluid temperature is too hot.
If the light illuminates while driving, im-
mediately stop the vehicle in a safe place
and let the engine idle until the warning
light turns off.
! Transmission control system warn-
ing
If the “AT OIL TEMP ”warning light flashes
after the engine has started, it may
indicate that the transmission control
system is not working properly. Contact
your nearest SUBARU dealer for service
immediately.
&Low tire pressure
warning light (U.S.-spec.
models)
When the ignition switch is turned to the
“ON ”position, the low tire pressure warn-
ing light will illuminate for approximately 2
seconds to check that the tire pressure
monitoring system (TPMS) is functioning
properly. If there is no problem and all tires
are properly inflated, the light will turn off.
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle
’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver ’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Instruments and controls/Warning and indicator lights
–CONTINUED –3-19

Instruments and controls/Warning and indicator lights
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of re-
placement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate stea-
dily after blinking for approximately one
minute, have the system inspected by
your nearest SUBARU dealer as soon as
possible.
WARNING
If this light does not illuminatebriefly after the ignition switch is
turned ON or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
If this light illuminates while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
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 possiblefor tire and sensor replacement and/
or system resetting.
If the light illuminates steadily after
blinking for approximately one min-
ute, promptly contact a SUBARU
dealer to have the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion 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. Therefore, be
sure to install the specified size for
the front and rear tires.

face; since having Vehicle Dy-
namics Control is no guarantee
that full vehicle control will be
maintained 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, 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 Dynamics Con-
trol 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 the
proper level as shown on the
vehicle placard attached to
the driver ’s side door pillar.
– Use only the specified tem-
porary spare tire to replace a
flat tire. With a temporary spare tire, the effectiveness of
the Vehicle Dynamics Control
system is reduced and this
should be taken into account
when driving the vehicle in
such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate cor-
rectly.
. The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely ne-
cessary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully accord-
ing to the road surface condi-
tions.
& System features
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine ’s output and the
wheels’ respective braking forces to help maintain traction and directional control.
.
Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dy-
namics Control operation indicator light.
. Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
NOTE
. The Vehicle Dynamics Control sys-
tem may be considered normal when
the following conditions occur.
–Slight twitching of the brake
pedal is felt.
– The vehicle or steering wheel
shakes to a small degree.
– An operating sound from the
engine compartment is heard
briefly when starting the engine
and when driving off after starting
the engine.

Driving tips for AWD models
WARNING
. Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-
tions.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
. When replacing or installing tire
(s), all four tires must be the
same for following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear
For the items (a) to (d), you must
obey the specification that is
8-4

printed on the tire placard. The
tire placard is located on the
driver’s door pillar.
If all of four tires are not the same
for items (a) to (h), serious me-
chanical damage could occur to
the drive train of your car, and
affect the following.
— Ride
— Handling
— Braking
— Speedometer/Odometer
calibration
— Clearance between the body
and tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
CAUTION
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 sizes may
result in severe mechanical damage
to the drive train of your vehicle.
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand.
By shifting power between the front and
rear wheels, SUBARU AWD can also
provide added traction during acceleration
and added engine braking force during
deceleration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging
the AWD system, you should keep the
following tips in mind.
. An AWD model is better able to climb
steeper roads under snowy or slippery conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles.
.
Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’s side.
. There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to “Towing”
F 9-14.

CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield or rear window, perform the
following procedure.
. To thaw the windshield wiper blades,
use the defroster with the airflow selection
in “
”and the temperature set for
maximum warmth until the wiper blades
are completely thawed. Refer to “Climate
control ”F 4-1.
. If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to “Defog-
ger and deicer ”F 3-108.
. To thaw the rear wiper blade, use the
rear window defogger. Refer to “Defoggerand deicer
”F 3-108.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow selection in “
”and the
temperature set for maximum warmth.
After the windshield gets warmed enough
to melt the frozen snow on it, wash it away
using the windshield washer. Refer to
“ Windshield washer ”F 3-98.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
Refer to “Hazard warning flasher ”F 3-8.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.
CAUTION
During high-speed driving, non-
freezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the vehicle speed.
NOTE
When the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades.
