Safety precautions when
driving&Seatbelt and SRS airbag
WARNING
.All persons in the vehicle must
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 must
always wear seatbelts when in
the vehicle. The SRS (Supple-
mental Restraint System) airbag
does not do away with the need to
fasten seatbelts. In combination
with the seatbelts, 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
CAUTION
Do 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/Pro-
vinces, 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 naviga-
tion system, first take the vehicle off
the road and stop it in a safe place.
&Driving with petsUnrestrained 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 infor-
mation, consult your veterinarian, local
animal protection society or pet shop.&Tire pressuresCheck and, if necessary, adjust the pres-
sure 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”F11-30.
WARNING
Driving 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 vehi-
cle control could lead to an accident.&Attaching accessories
WARNING
.Do not attach any accessories,
labels or stickers (other than
properly placed inspection stick-
ers) to the windshield. Such
items may obstruct your view.
.If it is necessary to attach an
accessory (such as an electronic
toll collection (ETC) device or
security pass) to the windshield,
consult your SUBARU dealer for
details on the proper location.

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 loca-
tion as soon as possible. Continuing
to drive with this light illuminated
may damage the rear differential and
other parts of the powertrain.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.

&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 recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pres-
sure label. (If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure
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 andcan 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 mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that thereplacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
Should the warning light illuminate steadily
after blinking for approximately one min-
ute, have the system inspected by your
nearest SUBARU dealer as soon as
possible.
WARNING
If 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. Instead, per-
form the following procedure. Other-
wise an accident involving serious
vehicle damage and serious perso-
nal injury could occur.
1) Keep driving straight ahead while
gradually reducing speed.
2) Slowly pull off the road to a safe
place.
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, refer to“Flat tires”F9-5.
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 vehicleis 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 evenafter starting the vehicle.
–The warning light illuminates
while 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 together
with the brake system warning light if the
EBD system malfunctions. For further
details of the EBD system malfunction
warning, refer to“Brake system warning
light”F3-21.
NOTEIf 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 approximately 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,
but it turns off while driving.
