2006 SUBARU IMPREZA warning light

Instruments and controls 3-13
Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON ” position.
The coolant temperature will vary in ac-
cordance 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. En-
gine operation is optimum with the engine
coolant at this temperature range and high
revving operation when the engine is not
warmed up enough should be avoided.
Outside temperature indica-
tor
1) U.S.-spec. models
2) Canada-spec. models
The outside temperature indicator shows
the outside temperature in a range from –
22 to 122 F ( –30 to 50 C).
The indicator can give a false reading un-
der 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 following a shut-
down.
When the actual outside temperature
falls outside the specified indicator range.
(Turbo model only)
Promptly put fuel in the tank when-
ever the low fuel warning light
comes on. Engine misfires as a re-
sult of an empty tank could cause
damage to the engine.

equipped)
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
Your vehicle is equipped with a seatbelt
warning device at the driver
’s seat, as re-
quired by current safety standards. There
is a seatbelt warning light in the combina-
tion meter.
If the driver has not yet fastened the seat-
belt when the ignition switch is turned to
the “ON ” position, the seatbelt warning
light will flash for 6 seconds, to warn that
the seatbelt is unfastened. If the driver ’s
seatbelt is not fastened, a chime will also
sound simultaneously.
If the driver ’s seatbelt is still not fastened
6 seconds later, the warning light will re-
main lit for 15 seconds. If the driver ’s seat-
belt is still not fastened even 15 seconds
later (21 seconds after turning ON the ig-
nition switch), the warning lights will alter-
nate between flashing and steady illumi-
nation at 15-second intervals, and the
chime will sound while the warning light is
flashing.
Alternate flashing and steady illumination
of the warning lights and sounding of the chime will continue until the driver fastens
the seatbelt.
NOTE
If the driver unfastens the seatbelt af-
ter fastening, the seatbelt warning de-
vice operates as follows according to
the vehicle speed.
At speeds lower than approximate-
ly 9 mph (15 km/h)
The warning light will alternate be-
tween flashing and steady illumina-
tion at 15-second intervals. The
chime will not sound.
At speeds higher than approxi-
mately 9 mph (15 km/h)
The warning light will alternate be-
tween flashing and steady illumina-
tion at 15-second intervals and the
chime will sound while the warning
light is flashing.
It is possible to cancel the warning
operation that follows the 6-second
warning after turning ON the ignition
switch by unfastening and refastening
the driver ’s seatbelt. When the ignition
switch is turned ON next time, howev-
er, the complete sequence of the warn-
ing operation resumes. For further de-
tails about canceling the warning oper-
ation, please contact your SUBARU
dealer.

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 approxi-
mately six seconds and go out. This
shows the SRS airbag and SRS side air-
bag (if equipped) and seatbelt pretension-
ers are in normal operation.
Front passenger ’s frontal air-
bag ON and OFF indicators
: Front passenger ’s frontal airbag
ON indicator
: 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 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 indi-
cators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators ex-
tinguish 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 air-
bag ON indicator will remain extinguished
while the OFF indicator will illuminate.
With the ignition switch turned to the “ON ”
position, if both the ON and OFF indica-
tors remain lit or extinguished simulta-
neously even after the system check peri-
od, the system is faulty. Contact your
SUBARU dealer immediately for an in-
spection.
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbag will not operate properly in
the event of a collision, which may
increase the risk of injury.

CHECK ENGINE warn-
ing light/Malfunction in-
dicator lamp
If this light comes on steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential prob-
lem somewhere in the emission control
system.
If the light comes on steadily:
If the light comes on 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 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 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 turn off immediately. It may
take several driving trips. If the light does
not go out, take your vehicle to your au-
thorized SUBARU dealer immediately.
If the light is blinking:
If the light is blinking while driving, an en-
gine misfire condition has been detected
which may damage the emission control
system.
To prevent serious damage to the emis-
sion control system, you should do the fol-
lowing.
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 pos-
sible. 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
running, 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 con-
dition but the light remains on, contact
your nearest SUBARU dealer immediate-
ly.
Oil pressure warning
light
If this light comes on 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 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 level is
low, add oil immediately. If the engine oil
If the CHECK ENGINE light comes
on while you are driving, have your
vehicle checked/repaired by your
SUBARU dealer as soon as possi-
ble. 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
’s warranty.

is at the proper level but the light remains
on, contact your nearest SUBARU dealer
immediately.
AT OIL TEMPerature
warning light (AT vehi-
cles)
The AT oil temperature warning light
comes on when the ignition switch is
turned to the
“ON ” position and goes out
after approximately two seconds.
If this light comes on when the engine is
running, it may indicate that the automatic
transmission fluid temperature is too hot.
If the light comes on while driving, it is un-
necessary to stop the vehicle, but avoid
driving up steep grades or in stop and go
traffic.
Automatic transmission control
system warning
If the light flashes after the engine starts,
it may indicate that the automatic trans-
mission control system is not working
properly. Contact your nearest SUBARU dealer for service immediately.
Rear differential oil tem-
perature warning light
(WRX-STI)
If this light comes on when the engine is
running, it may indicate that the rear differ-
ential oil temperature is too hot.
At this time, the driver
’s control center dif-
ferential will automatically cancel the cur-
rent torque-distribution ratio setting and
adopts its minimum ratio.
If the light comes on while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place.
Park the vehicle for several minutes. After
the light goes out, you can start driving.
If the light does not go out, 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
enough for the rear differential oil tem-
perature warning light to come on. It is
advisable to have the rear differential
oil replaced as soon as possible.
ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ” posi-
tion and goes out after approximately two
seconds.
This is an indication that the ABS system
is working properly.
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
comes on. Continued driving with
this light on can damage the rear dif-
ferential and other parts of the pow-
ertrain.
If the warning light behaves as fol-
lows, the ABS system may not work
properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.

3-18 Instruments and controls
With a vehicle equipped with an EBD sys-
tem, the ABS warning light comes on to-
gether with the brake system warning light
if the EBD system becomes faulty. For fur-
ther details of the EBD system fault warn-
ing, refer to “Brake system warning light ”.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal.
The warning light comes on right af-
ter 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 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 voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.
Brake system
warning light
This light has the following three func-
tions:
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 park-
ing 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 reservoir 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 nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN ” mark in the reser-
voir, do not drive the vehicle. Have the ve-
hicle towed to the nearest SUBARU deal-
er for repair.
Electronic Brake Force Distribution
(EBD) system warning (vehicles
with ABS)
The brake system warning light also illu-
The warning light does not come
on when the ignition switch is
turned to the “ON ” position.
The warning light comes on when
the ignition switch is turned to the “ON ” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12
km/h).
The warning light comes on dur-
ing driving.
If any of these conditions occur,
have the ABS system repaired at the
first available opportunity by your
SUBARU dealer.
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 properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.

minates if a malfunction occurs in the EBD
system. In that event, it comes on 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 ap-
plied harder than usual and the vehicle
’s
motion may therefore become somewhat
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 near-
est SUBARU dealer and have the system
inspected.
4. If both warning lights come on 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 system in-
spected.
6. If the brake fluid level is below the“
MIN ” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair.
Door open warning light
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.
All-Wheel Drive warn-
ing light (AWD AT vehi-
cles – if equipped)
The All-Wheel Drive warning light comes
on when the ignition switch is turned to the “ON ” position and goes out after approxi-
mately two seconds.
This light comes on when All-Wheel Drive
is disengaged and the drive mechanism is
switched to Front Wheel Drive for mainte-
nance or similar purposes (Non-turbo ve-
hicles).
It 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.
Intercooler water
spray warning light
(WRX-STI)
This light comes on when the water level
in the intercooler water spray tank falls to
the lower limit (approximately 0.4 US qt,
0.4 liter, 0.4 Imp qt).
Continuing to drive with the AWD
warning light flashing can damage
the powertrain. If the AWD warning
light starts to flash, promptly park in
a safe place and check whether the
tires have differing diameters and
whether any of the tires has an ex-
cessively low inflation pressure.
