Ambient temperature gauge
The ambient temperature gauge shows the ambient
temperature in a range from –22 °Fto122 °F(–30 °Cto
50 °C).
The gauge can give a false reading under any of the
following conditions: When there is too much sun.
During idling; while running at low speeds in a traffic
jam; when the engine is restarted immediately follow-
ing a shutdown. When the actual ambient temperature falls outside
the specified indicator range.Warning and indicator lights
Several of the warning and indicator lights come on
momentarily and then go out 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. The following lights come on:
Seatbelt warning light
SRS airbag system warning light
CHECK ENGINE warning light/Malfunction indica-
tor lamp
Charge warning light
Oil pressure warning light
AT OIL temperature warning light (AT vehicles)
ABS warning light
Brake system warning light
If any lights fail to come on, it indicates a burned-out
bulb or a malfunction of the corresponding system.
Consult your authorized SUBARU dealer for repair. Seatbelt warning light and chime
When the ignition switch is turned to the “ON” position,
the seatbelt warning light will come on and the remind-
er chime will sound for about six seconds to remind the
HS3047BA

driver to fasten the seatbelt.
The seatbelt warning light remains on for about six
seconds and turns off automatically after six seconds.
The seatbelt reminder chime will turn off by bucking
the driver’s side seatbelt or turn off automatically after
six seconds.
SRS airbag system warning light
When the ignition switch is turned to the “ON” position,
the SRS airbag system warning light will come on for
about six seconds and go out. This shows the SRS air-
bag and SRS side airbag (if equipped) and seatbelt
pretensioners are in normal operation.
If this light comes on while driving or remains illuminat-
ed even after a period of about 6 seconds from when
the ignition has been turned on, it may indicate that the
SRS airbag system or SRS side airbag system (if
equipped) or seatbelt pretensioner system is not work-
ing properly. Contact your nearest SUBARU dealer
immediately.
CHECK ENGINE warning light/
Malfunction indicator lamp
If the CHECK ENGINE light comes on while you
are driving, have your vehicle checked/repaired
by your SUBARU dealer as soon as possible.
Continued vehicle operation without having the
emission control system checked and repaired
as necessary could cause serious damage,
which may not be covered by your vehicle

NOTE
This light also comes on 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 indica-
tor lamp coming on could be a loose or missing fuel fill-
er 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 EN-
GINE warning light turn off immediately. It may take
several driving trips. If the light does not go out, take
your vehicle to your authorized SUBARU dealer im-
mediately. If the light is blinking:
If the light is blinking while driving, an engine misfire
condition has been detected which may damage the
emission control system.
To prevent serious damage to the emission control
system, you should do the following: Reduce vehicle speed.
Avoid hard acceleration.
Avoid steep uphill grades.
Reduce the amount of cargo, if possible.
Stop towing a trailer as soon as possible.
The CHECK ENGINE warning light may stop blinking and come on steadily after several driving trips. You
should have your vehicle checked by an authorized
SUBARU dealer immediately.
Charge warning light
If this light comes on when the engine is run-
ning, it may indicate that the charging system is not
working properly.
If the light comes on 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 deal-
er immediately. Oil pressure warning light
If this light comes on when the engine is run-
ning, it may indicate that the engine oil pressure is low
and the lubricating system is not working properly.
If the light comes on 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 lev-
el 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.

further details of the EBD system fault warning, refer
to “Brake system warning light”.
NOTE
If the warning light behavior is as shown below,
the ABS system may be considered normal.The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off. The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches about 8 mph (12 km/h). The warning light comes on 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 come on. This is due to the low battery volt-
age and does not indicate a malfunction. When the
battery becomes fully charged, the light will go out. Brake system warning light
Driving with the brake system warning light
on is dangerous. This indicates your brake sys- tem may not be working properly. If the light re-
mains on, have the brakes inspected by a
SUBARU dealer immediately.
If at all in doubt about whether the brakes are
operating properly, do not drive the vehicle.
Have your vehicle towed to the nearest
SUBARU dealer for repair.
This light has the following three functions: Parking brake warning
The light comes on 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 comes on when the brake fluid level has
dropped to near the “MIN” level of the brake fluid res-
ervoir with the ignition switch in the “ON” position and
with the parking brake fully released.
If the brake system warning light should come on 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 near-
est safe place and check the brake fluid level. If the flu-
(U.S.) (Canada)

id level is below the “MIN” mark in the reservoir, do not
drive the vehicle. Have the vehicle towed to the near-
est SUBARU dealer for repair.
Electronic Brake Force Distribution (EBD) sys-
tem warning (for vehicles with EBD)
The brake system warning light also illuminates if a
malfanction occurs in the EBD system. In that event, it
comes on together with the ABS warning light.
The EBD system may be faulty if the brake system
warning light and ABS warning light illuminate simulta-
neously during driving.
Even if the EBD system fails, the conventional 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 vehicle’s motion may there-
fore become somewhat harder to control.
If the brake system warning light and ABS warning
light illuminate simultaneously, take the followingsteps:
1. Stop the vehicle in the nearest safe, flat place. If
you cannot avoid parking the vehicle on a slope, use
chocks to prevent the vehicle from moving.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both warning lights go
out, the system is normal and no further action is nec- essary.
4. If both warning lights come on again and stay illu- minated 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 system inspect-
ed.
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.
Door open warning lights
The door open warning light comes on if any door or
the rear gate is not fully closed.
Always make sure this light is out before you start to drive. Low fuel warning light
The low fuel warning light comes on when the tank is
nearly empty about 2.3 U.S. gal. (9.0 liters, or 1.9 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 re-
plenished up to an internal fuel quantity of about
