accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range.
Also, high revving operation while the
engine is not sufficiently warmed up
should be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “In case of emergency ”in
chapter 9. Warning and indicator lights
Several of the warning and indicator lights
illuminate momentarily and then go out
when the ignition switch is initially turned
to the
“ON ”position. This permits check-
ing the operation of the bulbs.
Apply the parking brake and turn the
ignition switch to the “ON ”position. The
following lights illuminate:: Seatbelt warning light (The seatbelt warning light goes out
only when the driver fastens theseatbelt.)

Front passenger ’s frontal
airbag ON and OFF indica- tors
or: Front passenger ’s frontal airbag
ON indicator
or: Front passenger ’s frontal airbag
OFF 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 between the
map lights.
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
extinguish 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
advanced frontal airbag system monitor-ing.
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 extinguished.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger ’s frontal
airbag ON indicator will remain extin-
guished while the OFF indicator willilluminate.
If both the ON and OFF indicators remain
lit or extinguished simultaneously, the
system is faulty. Contact your SUBARU
dealer immediately 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 Instruments and controls

3-32Instruments and controls
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 go out 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 go out,
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.
& 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 go out 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 on, contact
your nearest SUBARU dealer immedi-
ately. &
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 go out 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 on,
contact your nearest SUBARU dealer
immediately.

&AT OIL TEMP warning
light (AT models)
The AT oil temperature warning light “AT
OIL TEMP ”illuminates when the ignition
switch is turned to the “ON ”position and
goes out after approximately 2 seconds.
If this light illuminates when the engine is
running, it may indicate that the automatic
transmission 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 goes off. ! Automatic transmission control
system warning
If the “AT OIL TEMP ”warning light flashes
after the engine has started, it may
indicate that the automatic 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 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 aspossible.Instruments and controls

If any of these conditions occur,
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
The ABS warning light illuminates to-
gether with the brake system warning light
if the EBD system becomes faulty. For
further details of the EBD system fault
warning, refer to “Brake system warning
light ”.
NOTE
If the warning light behavior is as
described in the following conditions,
the ABS system may be considerednormal. . The warning light illuminates right
after the engine is started but goes out
immediately, remaining off. . The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).. The warning light illuminates during
driving, but it goes out immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction. When the battery becomes fully charged,
the light will go out.
& Brake system
warning light
WARNING
. Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair.
This light has the following three functions: ! Parking brake warning
The light illuminates with the parking
brake applied while the ignition switch is
in the “ON ”position. It goes out 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 faulty 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- Instruments and controls

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 go out, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights illuminate again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the “MIN ”mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the systeminspected.
6. If the brake fluid level is below the “ MIN ”mark, DO NOT drive the vehicle.
Instead, have the vehicle towed to the
nearest SUBARU dealer for repair.
& Low fuel warning light
The low fuel warning light illuminates
when the tank is nearly empty approxi- mately 2.6 US gal (10.0 liters, or 2.2 Imp
gal). It only operates when the ignition
switch is in the
“ON ”position.
NOTE
This light does not go out unless the
tank is replenished up to an internal
fuel quantity of approximately 3.7 US
gal (14 liters, 3.1 Imp gal).
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light
illuminates. Engine misfires as a
result of an empty tank could cause
damage to the engine.
& Door open warning light
When any of the doors, the rear gate
(Station wagon) or the trunk lid (Sedan) is
not fully closed, the door open warning
light illuminates.
For a vehicle without SI-DRIVE, the
open door is indicated by the correspond-
ing part of the door open warning light.
For a vehicle with SI-DRIVE, the opening
door is indicated on the multi-information
display. Always make sure this light is out before
you start to drive. &
All-Wheel Drive
warning light
(AT models)
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.
The All-Wheel Drive warning light illumi-
nates when the ignition switch is turned tothe “ON ”position and goes out after the
engine has started. ! For 5-speed automatic transmis-
sion vehicles
This light flashes if the vehicle is driven
with tires of different diameters fitted on its
wheels or with the air pressure exces-
sively low in any of its tires.
