WARNING
CAUTIONSafety precautions when
driving & Seatbelt and SRS airbag WARNING. All persons in the vehicle should
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-
dent.
. To obtain maximum protection in
the event of an accident, the
driver and all passengers in the
vehicle should always wear seat-
belts when the vehicle is moving.
The SRS (Supplemental Restraint
System) airbag does not do away
with the need to fasten seatbelts.
In combination with the seat-
belts, it offers the best combined
protection in case of a serious
accident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag.

& Car phone/cell phone and
driving CAUTIONDo not use a car phone/cell phone
while driving; it may distract your
attention from driving and can lead
to an accident. If you use a car
phone/cell phone, pull off the road
and park in a safe place before
using your phone. In some States/
Provinces, only hands-free phones
may legally be used while driving.
& Driving vehicles equipped
with navigation system
WARNING
Do not allow the monitor to distract
your attention from driving. Also, do
not operate the controls of the
navigation system while driving.
The loss of attention to driving
could lead to an accident. If you
wish to operate the controls of the
navigation system, first take the
vehicle off the road and stop it in a
safe place. & Driving with pets Unrestrained pets can interfere with your
driving and distract your attention from
driving. In a collision or sudden stop,
unrestrained pets or cages can be thrown
around inside the vehicle and hurt you or
your passengers. Besides, the pets can
be hurt under these situations. It is also for
their own safety that pets should be
properly restrained in your vehicle. Re-
strain a pet with a special traveling
harness which can be secured to the rear
seat with a seatbelt or use a pet carrier
which can be secured to the rear seat by
routing a seatbelt through the carrier ’ s
handle. Never restrain pets or pet carriers
in the front passenger ’ s seat. For further
information, consult your veterinarian,
local animal protection society or pet
shop.
& Tire pressures Check and, if necessary, adjust the
pressure of each tire (including the spare)
at least once a month and before any long
journey.
Check the tire pressure when the tires are
cold. Use a pressure gauge to adjust the
tire pressures to the values shown on the
tire placard. For detailed information, refer
to “ Tires and wheels ” F 11-31. WARNINGDriving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of
vehicle control could lead to an
accident.7

Warning and indicator lights Several of the warning and indicator lights
illuminate when the ignition switch is
initially turned to the “ ON ” position. This
permits checking the operation of the
bulbs.
Apply the parking brake and turn the
ignition switch to the “ ON ” position. For
the system check, the following lights
illuminate and then turn off after several
seconds or after the engine has started.
: Seatbelt warning light
(The seatbelt warning light turns off
only when the driver fastens the
seatbelt.)

Instruments and controls/Warning and indicator lights
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
indicator will be off.
. The warning indicator may appear
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 indicatorThis indicator appears 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.
& Rear differential oil
temperature warning
light (STI)
CAUTION
If the R.DIFF TEMP warning light
illuminates, reduce vehicle speed
and stop the vehicle in a safe
location as soon as possible. Con-
tinuing to drive with this light illumi-
nated may damage the rear differ- ential and other parts of the power-
train.
If this light illuminates when the engine is
running, it may indicate that the rear
differential oil temperature is too hot.
At this time, the driver ’ s control center
differential will automatically cancel the
current torque-distribution ratio setting and
adopt its minimum ratio.
If the light illuminates while driving, reduce
vehicle speed and stop the vehicle in the
nearest safe location. Park the vehicle for
several minutes. After the light turns off,
you can start driving.
If the light does not turn off, contact the
nearest SUBARU dealer for service.
NOTE . If the tire pressures are not correct
and/or the tires are not all the same
size and brand, the rear differential will
be heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.
. The rear differential oil will deterio-
rate if its temperature increases en-
ough for the rear differential oil tem-
perature warning light to illuminate. It is
advisable to have the rear differential
oil replaced as soon as possible.3-18

& 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.
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.
WARNINGIf this light does not illuminate
briefly 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 causesInstruments and controls/Warning and indicator lights
– CONTINUED –3-19

Instruments and controls/Warning and indicator lights
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.
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 to a vehicle speed of at
least 20 mph (32 km/h). After adjust-
ing 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.
Therefore, be sure to install the
specified size for the front and rear
tires.
& ABS warning light
CAUTION. If any of the following conditions
occur, we recommend that you
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
– The warning light does not
illuminate when the ignition
switch is turned to the “ ON ”
position.
– The warning light illuminates
when the ignition switch is
turned to the “ ON ” position,
but it does not turn off even after starting the vehicle.
– The warning light illuminates
during driving.
. When the warning light is on (and
the brake system warning light is
off), the ABS function shuts
down. However, the conventional
brake system continues to oper-
ate normally.
The ABS warning light illuminates to-
gether with the brake system warning light
if the EBD system malfunctions. For
further details of the EBD system mal-
function warning, refer to “ Brake system
warning light ” F 3-21.
NOTE If the warning light behavior is as
described in the following conditions,
the ABS system may be considered
normal.
. The warning light illuminates when
the ignition switch is turned to the
“ ON ” position and turns off approxi-
mately 2 seconds after the engine has
started.
. The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
. The warning light remains illumi-
nated after the engine has been started,3-20

& Door open warning
lightThe warning light illuminates if any door or
the trunk lid is not fully closed. This
function is effective even if the ignition
switch is in the “ LOCK ” / “ OFF ” or “ ACC ”
position, or the key is removed from the
ignition switch.
Always make sure this light is not illumi-
nated before you start to drive.
& All-Wheel Drive warn-
ing light (if equipped)This light flashes if the vehicle is driven
with tires of differing diameters fitted on
the wheels or with an excessively low air
pressure in any of the tires.
WARNING
Continued driving with the AWD
warning light flashing can lead to
powertrain damage. If the AWD
warning light flashes, promptly park
in a safe place then check whether
all four tires are the same diameter
and whether any of the tires has a
puncture or has lost air pressure for
some other reason. & Power steering warn-
ing light (except STI) This warning light illuminates when the
ignition switch is turned to the “ ON ”
position and turns off after the engine
has started. This indicates that the warn-
ing system is working properly.
While the engine is running, this warning
light illuminates when a malfunction has
been detected in the electric power steer-
ing system.
CAUTIONWhen 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.
NOTE If 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 con-
trol computer and drive motor, from
overheating. . The steering wheel is operated fre-
quently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing 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 fre-
quently, that may result in a malfunc-
tion of the power steering control
system.
& LED headlight warning
light (if equipped) This light illuminates if the LED headlights
malfunction. Have your vehicle inspected
at a SUBARU dealer as soon as possible.Instruments and controls/Warning and indicator lights
