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, apply the
parking brake and 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
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
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
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. When this light illuminates, fill the fuel tank immedi-
ately.
NOTE
This light does not turn off 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.

is inoperative, the Vehicle Dynamics
Control system becomes unable to
provide ABS control. As a result, the
Vehicle Dynamics Control system
also becomes inoperative, causing
the warning light to illuminate.
Though both the Vehicle Dynamics
Control and ABS systems are inop-
erative in this case, the ordinary
functions of the brake system are
still available. You will be safe while
driving with this condition, but drive
carefully and have your vehicle
checked at a SUBARU dealer as
soon as possible.

2) Except U.S.-spec. models
When the outside temperature drops to 37 8F(3 8C) or lower, the temperature
indication flashes to show that the road
surface may be frozen.
If the outside temperature drops to 37 8F
(3 8C) or lower while the display is giving
an indication other than the outside
temperature, the display switches to the
outside temperature indication and flashes
for 5 seconds before returning to its
original indication.
If the display is already indicating an
outside temperature of 37 8F(3 8C) or lower
when the ignition switch is turned to the “
ON ”position, the indication does not
flash. NOTE
The outside temperature indication
may differ from the actual outside
temperature. The road surface freeze
warning indication should be treated
only as a guide. Be sure to check the

This indication shows the rate of fuel
consumption at the present moment. &
Average fuel consumption
1) U.S.-spec. models
2) Except U.S.-spec. models
This indication shows the average rate of
fuel consumption since the trip meter was
last reset.
When either of the trip meter indications is
reset, the corresponding average fuel
consumption value is also reset. NOTE . The indicated values vary in accor-
dance with changes in the vehicle ’s
running conditions. Also, the indicated
values may differ slightly from the
actual values and should thus be
treated only as a guide.. When either trip meter indication is
reset, the average fuel consumption

corresponding to that trip meter indica-
tion is not shown until the vehicle has

.In freezing weather, be sure that
the wiper blades are not frozen to
the windshield or rear window
before switching on the wipers.
Attempting to operate the wiper
with the blades frozen to the
window glass could cause not
only the wiper blades to be
damaged but also the wiper mo-
tor to burn out. If the wiper
blades are frozen to the window
glass, be sure to operate the
defroster, windshield wiper dei-
cer (if equipped) or rear window
defogger before turning on the
wiper.
. If the wipers stop during opera-
tion because of ice or some other
obstruction on the window, the
wiper motor could burn out even
if the wiper switch is turned off. If
this occurs, promptly stop the
vehicle in a safe place, turn the
ignition switch to the “LOCK ”
position and clean the window
glass to allow proper wiper op-eration.
. Use clean water if windshield
washer fluid is unavailable. In
areas where water freezes in
winter, use SUBARU Windshield
Washer Fluid or the equivalent. Refer to
“Windshield washer
fluid ”F 11-38.
Also, when driving the vehicle
when there are freezing tempera-
tures, use non-freezing type wi-
per blades.
. Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.
NOTE . The wiper operates only when the
ignition switch is in the “ON ”or “Acc ”
position. . The front wiper motor is protected
against overloads by a circuit breaker.
If the motor operates continuously
under an unusually heavy load, the
circuit breaker may trip to stop the
motor temporarily. If this happens, park
your vehicle in a safe place, turn off the
wiper switch, and wait for approxi-
mately 10 minutes. The circuit breaker
will reset itself, and the wipers will
again operate normally.. Clean your wiper blades and win-
dow glass periodically with a washer
solution to prevent streaking, and to
remove accumulations of road salt or road film. Keep the washer button
depressed at least for 1 second so that
washer solution will be sprinkled all
over the windshield or rear window..
Grease, wax, insects or other mate-
rial on the windshield or the wiper
blade results in jerky wiper operation
and streaking on the glass. If you
cannot remove those streaks after
operating the washer or if the wiper
operation is jerky, clean the outer sur-
face of the windshield or rear window
and the wiper blades using a sponge or
soft cloth with a neutral detergent or
mild-abrasive cleaner. After cleaning,
rinse the window glass and wiper
blades with clean water. The glass is
clean if no beads form on the glass
when you rinse with water.. If you cannot eliminate the streaking
even after following this procedure,
replace the wiper blades with new
ones. For replacement instructions,
refer to “Replacement of wiper blades ”
