They could accidentally injure
themselves or others through
inadvertent operation of the ve-
hicle. Also, on hot or sunny days,
the temperature in a closed ve-
hicle could quickly become high
enough to cause severe or pos-
sibly fatal injuries.
. Help prevent children, adults or
animals from locking themselves
in the trunk. On hot or sunny
days, the temperature in the
trunk could quickly become high
enough to cause death or serious
heat-related injuries including
brain damage to anyone locked
inside, particularly for small chil-dren.
. When leaving the vehicle, close
all windows and lock all doors.
Also make certain that the trunk
is closed.
For instructions and precautions, carefully
read the following sections. . For the seatbelt system, refer to “Seat-
belts ”F 1-12.
. For the child restraint system, refer to
“ Child restraint systems ”F 1-25.
. For the SRS airbag system, refer to
“ *SRS airbag (Supplemental Restraint System airbag)
”F 1-38.
& Engine exhaust gas (carbon monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly. .
If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the trunk lid or rear gate
closed while driving to prevent
exhaust gas from entering thevehicle.
& Drinking and driving
WARNING
Drinking and then driving is very
dangerous. Alcohol in the blood-
stream delays your reaction and
impairs your perception, judgment
and attentiveness. If you drive afterdrinking –even if you drink just a
little –it will increase the risk of
being involved in a serious or fatal
accident, injuring or killing yourself,
your passengers and others. In
addition, if you are injured in the
accident, alcohol may increase the
severity of that injury.

&Modification of your vehicle
CAUTION
Your vehicle should not be modified
other than with genuine SUBARU
parts and accessories. Other types
of modifications could affect its
performance, safety or durability,
and may even violate governmental
regulations. In addition, damage or
performance problems resulting
from modification may not be cov-
ered under warranties.
& 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 petshop.
& Tire pressures
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
vehicle control could lead to anaccident.
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, referto “Tires and wheels ”F 11-35. &

indicator
The front passenger ’s frontal airbag ON
and OFF indicators show you the status of
the front passenger ’s SRS frontal airbag.
The indicators are located next to the
clock in the center portion of the dash-board.
When the ignition switch is turned to the “ ON ”position, both the ON and OFF
indicators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators turn
off for 2 seconds. After that, one of the indicators illuminates depending on the
status of the front passenger
’s SRS frontal
airbag determined by the SUBARU ad-
vanced frontal airbag system monitoring.
If the front passenger ’s SRS frontal airbag
is activated, the passenger ’s frontal airbag
ON indicator will illuminate while the OFF
indicator will remain off.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger ’sfrontal
airbag ON indicator will remain off while
the OFF indicator will illuminate.
With the ignition switch turned to the “ON ”
position, if both the ON and OFF indica-
tors remain illuminated or off simulta-
neously even after the system check
period, the system is malfunctioning.
Contact your SUBARU dealer immedi-
ately for an inspection.
& CHECK ENGINE warn-
ing light/Malfunction
indicator lamp
CAUTION
If the CHECK ENGINE warning light/
malfunction indicator lamp illumi-
nates while you are driving, have
your vehicle checked/repaired by
your SUBARU dealer as soon as
possible. Continued vehicle opera- tion without having the emission
control system checked and re-
paired as necessary could cause
serious damage, which may not be
covered by your vehicle
’s warranty.
If this light illuminates steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential
problem somewhere in the emission con-
trol system. ! If the light illuminates steadily
If the light illuminates steadily while driving
or does not turn off after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately.
NOTE
This light also illuminates when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator lamp coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE

warning light/malfunction indicator lamp
turn off immediately. It may take several
driving trips. If the light does not turn off,
take your vehicle to your authorized
SUBARU dealer immediately. !If the light is blinking
If the light is blinking while driving, an
engine misfire condition has been de-
tected which may damage the emission
control system.
To prevent serious damage to the emis-
sion control system, you should conform
to the following instructions. . Reduce vehicle speed.
. Avoid hard acceleration.
. Avoid steep uphill grades.
. Reduce the amount of cargo, if possi-
ble.. Stop towing a trailer as soon as
possible.
The CHECK ENGINE warning light/mal-
function indicator lamp may stop blinking
and illuminate steadily after several driv-
ing trips. You should have your vehicle
checked by an authorized SUBARU deal-
er immediately. &

creases over the appropriate range, the
indicator light/warning light blinks in RED.
At this time, decelerate the vehicle. After
the blinking REDlight turns off, you can
drive the vehicle normally. However, if the
indicator light/warning light often blinks inRED , the electrical system may be mal-
functioning. Contact your SUBARU dealer
for an inspection.
If the engine coolant temperature in-
creases further, the indicator light/warning
light illuminates in REDcontinuously. At
this time, the engine may be overheating.
Safely stop the vehicle as soon as
possible, and refer to the emergency
steps for the case of engine overheating.
Refer to “Engine overheating ”F9-12.
After that, have the system checked by
your nearest SUBARU dealer.
NOTE
If the engine is restarted after a certain
driving condition, this indicator light/
warning light may illuminate in RED.
However, this is not a malfunction if the
indicator light/warning light turns off
after a short time. &
Charge warning light
If this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good
condition but the light remains illuminated,
contact your nearest SUBARU dealer
immediately. &Oil pressure warning light
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
If this light illuminates when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil is at the proper level but the light remains
illuminated, contact your nearest
SUBARU dealer immediately.
& Engine low oil level
warning light
The engine low oil level warning light
illuminates when the ignition switch is
turned to the “ON ”position and turns off
after approximately 2 seconds.
This light also illuminates when the engine
oil level decreases to the lower limit. The
illuminating conditions and remaining oil
level are shown in the following items.
2.5 L models:. when the ignition switch is in the “ON ”
position but the engine is not running:
approximately 1.9 US qt (1.8 liters, 1.6
Imp qt) . while the engine is running: approxi-
mately 3.2 US qt (3.0 liters, 2.6 Imp qt)
3.6 L models: . when the ignition switch is in the “ON ”
position but the engine is not running:
approximately 4.0 US qt (3.8 liters, 3.3
Imp qt) . while the engine is running: approxi-
mately 5.6 US qt (5.3 liters, 4.7 Imp qt)
If the engine low oil level warning light
illuminates while driving, park the vehicle

at a safe and level location, and then
check the engine oil level. When the
engine oil level is not within the normal
range, refill with engine oil if necessary.
Refer to“Engine oil ”F 11-12.
If the warning light does not turn off after
refilling with engine oil or the warning light
illuminates even though the engine oil
level is within the normal range, have the
system checked by a SUBARU dealer.
NOTE . The engine low oil level warning
light will not turn off immediately even
if you replace or add engine oil. It will
turn off only when the vehicle is idling
and the engine is warmed up comple-
tely.. When the vehicle is considerably
inclined on an uphill or steep slope, the
warning light may illuminate tempora-
rily due to the movement of engine oil
in the engine. & AT OIL TEMP warning
light (AT and CVT mod-els)
The AT oil temperature warning light “AT
OIL TEMP ”illuminates when the ignition
switch is turned to the “ON ”position and
turns off after approximately 2 seconds. 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 go out.
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 thosetires.)
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- Instruments and controls

NOTE . When the ignition switch is turned to
the “LOCK ”position with the electronic
parking brake applied, the brake sys-
tem warning light remains illuminated
for approximately 30 seconds and then
turns off.. When the electronic parking brake
switch is pressed to apply the electro-
nic parking brake while the ignition
switch is in the “LOCK ”position, the
brake system warning light illuminates,
remains illuminated for approximately
30 seconds and then turns off.. Even if the brake system warning
light flashes, if the warning light beha-
vior is as described in the following
examples, the electronic parking brake
system is not malfunctioning.
–The warning light turns off when
the electronic parking brake is ap-
plied or released. – The warning light turns off when
the ignition switch is turned to the “ ON ”position again.
. The brake system warning light may
flash when the engine is started im-
mediately after the electronic parking
brake is applied or released. However,
the electronic parking brake system is
not malfunctioning if the warning light
turns off after the electronic parking brake is applied or released after that. .
The brake system warning light may
flash after the electronic parking brake
is frequently applied and released.
However, the electronic parking brake
system is not malfunctioning if the light
turns off for a short period of time.
This light has the following functions: ! Parking brake warning
The light illuminates with the parking
brake applied while the ignition switch is
in the “ON ”position. It turns off when the
parking brake is fully released. ! Brake fluid level warning
This light illuminates when the brake fluid
level has dropped to near the “MIN ”level
of the brake fluid reservoir with the ignition
switch in the “ON ”position and with the
parking brake fully released.
If the brake system warning light should
illuminate while driving (with the parking
brake fully released and with the ignition
switch positioned in “ON ”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN ”mark in the
reservoir, do not drive the vehicle. Have
the vehicle towed to the nearest SUBARU dealer for repair. !
Electronic Brake Force Distribution
(EBD) system warning
The brake system warning light also
illuminates if a malfunction occurs in the
EBD system. In that event, it illuminates
together with the ABS warning light.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
during driving.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehi-cle ’s motion may therefore become some-
what harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe,
flat place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights turn off, the EBD system
may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights illuminate again
and remain illuminated after the engine
