Starting and operating
– CONTINUED –
If the warning light behaves as follows, the ABS
system may not be working properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake
system continues to operate normally. yThe 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.
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.

Starting and operating
Electronic Brake Force Distribution
(EBD) system
The EBD system maximizes the effectiveness of the
brakes by allowing the rear brakes to supply a greater
proportion of the braking force. It functions by adjust-
ing the distribution of braking force to the rear wheels
in accordance with the vehicle’s loading condition and
speed.
The EBD system is an integral part of the ABS system
and uses some of the ABS system’s components to
perform its function of optimizing the distribution of
braking force. If any of the ABS components used by
the EBD function fails, the EBD system also stops
working.
When the EBD system is operating, you may hear a
chattering noise or feel a slight vibration in the brake
pedal. This is normal and does not indicate a malfunc- tion.
„
Steps to take if EBD system fails
If a malfunction occurs in the EBD system, the system
stops working and the brake system warning light and
ABS warning light come on simultaneously.
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 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.
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.
Have your vehicle towed to the nearest
SUBARU dealer for repair.

Parking your vehicle „
Parking brake
To set the parking brake, press the brake pedal firmly
and hold it down while fully pulling up the parking
brake lever.
To release the parking brake, pull the lever up slightly,
press the release button, then lower the lever while
keeping the button pressed.
When the parking brake is set while the engine is run-
ning, the parking brake warning light comes on. After
starting the vehicle, be sure that the warning light has
gone out before the vehicle is driven. Refer to the “Warning and indicator lights” section (chapter 3).
Never drive while the parking brake is set be-
cause this will cause unnecessary wear on the
brake linings. Before starting to drive, always
make sure that the parking brake has been fully
released.
„ Parking tips
When parking your vehicle, always set the parking brake firmly and put the shift lever in the “1” (1st) for an
upgrade or “R” (Reverse) for a downgrade for manual
transmission vehicles, or in the “P” (Park) position for
automatic transmission vehicles. Always set the park-
ing brake firmly when parking your vehicle. Never rely
on the transmission alone to hold the vehicle.

Driving tips
– CONTINUED –
tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
y Backing up with a trailer is difficult and takes prac-
tice. When backing up with a trailer, never accelerate
or steer rapidly. When turning back, grip the bottom of
the steering wheel with one hand and turn it to the left
for a left turn, and turn it to the right for a right turn. y If the ABS warning light illuminates while the vehicle
is in motion, stop towing the trailer and have repairs
performed immediately by the nearest SUBARU deal- er. T
Driving on grades
y Before going down a steep hill, slow down and shift
into lower gear (if necessary, use 1st gear) in order to
utilize the engine braking effect and prevent overheat-
ing of your vehicle’s brakes. Do not make sudden
downshifts.y When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating.y When driving uphill in hot weather, pay attention to
the water temperature gauge pointer (for all vehicles)
and AT OIL TEMP warning light (for AT vehicles) since
the engine and transmission are relatively prone to
overheating under these conditions. If the water tem-
perature gauge pointer approaches the OVERHEAT
zone or the AT OIL TEMP warning light illuminates,
immediately switch off the air conditioner and stop the
vehicle at the nearest safe place. Refer to the “Engine
overheating” section in chapter 9, and “Warning and
indicator lights” section in chapter 3. y If your vehicle has an automatic transmission, avoid
using the accelerator pedal to stay stationary on an
uphill slope instead of using the parking brake or foot
brake. That may cause the transmission fluid to over-
heat. Also, if your vehicle is equipped with an automat-
ic transmission, avoid driving with the gear selector le-
ver in “D” when towing a heavy trailer to prevent fluid

In case of emergency
1) Spare fuse
2) FWD connector
NOTE
(If your vehicle is AWD with automatic transmis-
sion, except Turbo models) Before driving your
vehicle with the temporary spare tire, put a spare fuse inside the FWD connector in the main fuse
box located in the engine compartment and con-
firm that the Front-wheel drive warning light
“AWD” in the combination meter comes on. The
all wheel drive capability of the vehicle has now
deactivated. After re-installing the conventional
tire, remove the spare fuse from the FWD connec-
tor in order to reactivate all wheel drive.
Never tow a trailer when the temporary spare
tire is used. The temporary spare tire is not de-
signed to sustain the towing load. Use of the
temporary spare tire when towing can result in
failure of the spare tire and/or less stability of
the vehicle and may lead to an accident.
Never use any temporary spare tire other than
the original. Using other sizes may result in se-
vere mechanical damage to the drive train of
your vehicle.

Intercooler water spray (WRX-STi)
Add water to the intercooler water spray tank when the
intercooler water spray warning light in the combina-
tion meter comes on. The warning light comes on
when the water in the tank has decreased to approxi-
mately 0.4 liters (0.4 US qt, 0.4 Imp qt). The tank is located on the right hand side of the trunk.
NOTE y
Use only pure water for refilling.
y In cold weather (when you do not use the inter-
cooler water spray), keep the tank half-empty in
case the water freezes. A larger amount of water
could break the tank if it froze.
