light SUBARU IMPREZA 2005 2.G Repair Manual

3-24
Instruments and controls
If the warning light behaves as follows, the ABS
system may not work properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake
system continues to operate normally. y
The warning light does not come on when the
ignition switch is turned to the “ON” position. y 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). y The warning light comes on during driving.
If these occur, have the ABS system repaired at
the first available opportunity by your SUBARU
dealer.
With a vehicle equipped with an EBD system, the ABS
warning light comes on together 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 be- low, the ABS system may be considered normal. y
The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off. y 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). y 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
yDriving 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. y If at all in doubt about whether the brakes are
operating properly, do not drive the vehicle.

This light has the following three functions: T 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. T 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-
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. T Electronic Brake Force Distribution (EBD) sys-
tem warning (for vehicles with ABS)
The brake system warning light also illuminates 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 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 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 in- spected.
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 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 warning light
(for AWD AT vehicles – if
equipped)
The all-wheel drive warning light comes on when the
ignition switch is turned to the “ON” position and goes
out after about two seconds.
This light comes on when All Wheel Drive is disen-
gaged and the drive mechanism is switched to Front
Wheel Drive for maintenance or similar purposes
(Non-turbo vehicles).
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.
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 dif-
fering diameters and whether any of the tires
has an excessively low inflation pressure.
„ Intercooler water spray warning
l i g h t ( W R X - S T i )
This light comes on when the water level in the inter-
cooler water spray tank falls to the lower limit (about
0.4 US qt, 0.4 liter, 0.4 Imp qt).

Illumination brightness control
(WRX-STi)
The brightness of the combination meter can be ad-
justed in five steps with the headlight switch either the
OFF position or the “ ” or “ ” position.
When the control dial is turned upward or downward,
the instrument panel’s illumination brightness is indi-
cated by the trip meter. The brightness is shown in five
steps from “ ” (dimmest) to “ ” (brightest).
If the control dial is not turned for three seconds, the
trip meter returns to its original trip meter indication.
Headlight beam leveler (U.S.-spec. WRX-STi)
The WRX-STi version has High-Intensity Discharge
(HID) headlights on the low beam setting. The HID
headlights generate more light than conventional halo-
gen headlights. Therefore a driver of an oncoming ve-
hicle may experience too much glare when your head-
light beam height adjustment is high due to the vehicle
carrying heavy load.
The headlight beam leveler can be used to adjust
beam height to avoid such a condition.
The higher the number the knob is turned to, the lower
