When you feel the ABS system operating, you should maintain
constant brake pedal pressure. Do not pump the brake pedal
since doing so may defeat the operation of the ABS system.
The ABS system prevents the lock-up of wheels which may occur during
sudden braking or braking on slippery road surfaces. This helps prevent
the loss of steering control and directional stability caused by wheellock-up.
When the ABS system is operating, you may hear a chattering noise or
feel a slight vibration in the brake pedal. This is normal when the ABSoperates. The ABS system will not operate when the vehicle speed is below
approximately 6 mph (10 km/h). ABS system self-check
You may feel a slight shock in the brake pedal and hear the operating
sound of ABS from the engine compartment just after the vehicle is
started. This is caused by an automatic functional test of the ABS sys-
tem being carried out and does not indicate any abnormal condition. ABS warning light
HB4010GA
The ABS warning light comes on when the ignition switch is turned to the “ON” position and goes out after about two seconds.

This is an indication that the ABS system is working properly.
CAUTION
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; how-
ever, the conventional brake system continues to operate normal-
ly. 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 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 below, the ABS sys- tem may be considered normal. The warning light comes on right after 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 about 8mph (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 en-
gine 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.

7-36VDC (Vehicle Dynamics Control) system (if equipped)
WARNING
Always use the utmost care in driving — overconfidence because
you are driving with a VDC system equipped vehicle could easily lead to a serious accident.
CAUTION
Even if your vehicle is equipped with VDC, winter tires should
be used when driving on snow-covered or icy roads; in addition,
vehicle speed should be reduced considerably. Simply having a
VDC system does not guarantee that the vehicle will be able toavoid accidents in any situation. Activation of the VDC system is an indication that the road
being travelled on has a slippery surface; since having VDC is no
guarantee that full vehicle control will be maintained at all timesand under all conditions, its activation should be seen as a sign
that the speed of the vehicle should be reduced considerably. Whenever suspension components, steering components, or
an axle are removed from a vehicle equipped with VDC, have anauthorized SUBARU dealer perform an inspection of that system. The following precautions should be observed in order to
ensure that the VDC system is operating properly:
–All four wheels should be fitted with tires of the same size,
type, and brand. Furthermore, the amount of wear should bethe same for all four tires.– Keep the tire pressure at the proper level as shown on the
label attached to the vehicle ’s door pillar.
– Use only the special temporary spare tire to replace a flat
tire. With a temporary spare tire, the effectiveness of the VDC
system is reduced and this should be taken into account whendriving with vehicle.

7-38
when the vehicle is fitted with snow tires or winter tires
Activation of the VDC system will cause operation of the steering
wheel to feel slightly different compared to that for normal condi- tions. Even if the vehicle is equipped with a VDC system, it is important
that winter tires be used when driving on snow-covered or icyroads. (All four wheels should be fitted with tires of the same sizeand brand). It is always important to reduce speed when approaching a cor-
ner, even if the vehicle is equipped with VDC. All four wheels should be fitted with tires of the same size, type,
and brand; furthermore, the amount of wear should be the same for
all four tires. If these precautions are not observed and non-match-ing tires are used, it is quite possible that the VDC system will beunable to operate correctly as intended. Always turn off the engine before replacing a tire as failure to do
so may render the VDC system unable to operate correctly.
VDC system monitor
HB4010FB
nVDC OFF indicator light
The VDC OFF indicator light turns on initially when the ignition key
is turned to the ON position; it subsequently turns off 6 seconds after
the engine is started. This light turns on to indicate that the VDC system is in non-opera-
tion mode. This does not constitute failure of the VDC system.

7-40The following situations could indicate a malfunction of the VDC sys-
tem; if any should occur, have an authorized SUBARU dealer carry
out an inspection of the system at the first available opportunity.
The VDC warning light does not turn on when the ignition key is
turned to the ON position. The VDC warning light does not turn off either when the engine is
started or when the vehicle reaches a speed of approximately 8 mph(12 km/h). The VDC warning light turns on while the vehicle is being driven.
When a malfunction has occurred in the VDC electrical system,
only the VDC warning light will turn on. In such an event, the ABS will
still be operating normally. The VDC warning light will also turn on when a problem occurs
with the ABS or VDC electronic control systems.
Because the VDC system controls each brake through the ABS,
whenever the ABS stops operating due to a malfunction in that electri-
cal system, the VDC will also become unable to control all four
brakes. Thus VDC system operation halts and the VDC warning light
turns on. Although both the VDC system and the ABS will be inoper-able in this situation, it will still be possible to stop the vehicle using
normal braking. The VDC system and the ABS do not adversely affect
operation of the vehicle in any way when they are inoperable; how-
ever should such a situation occur, drive with care and have an autho-
rized SUBARU dealer carry out an inspection of those systems at the
first available opportunity. NOTE
When the VDC warning light turns on and off in the following way,
it indicates that the VDC system is operating normally. Although turning on after the engine has been started, the
warning light quickly turns off and stays off. The warning light turns on after the engine is started and does
not turn off until the vehicle reaches a speed of 8 mph (12 km/h). The warning light turns on when the vehicle is being driven; it
then turns off and stays off.

VDC OFF switch
HB7028ABHB7022AA
Note: Even when the lighting switch is turned to the “p ” or “a ” posi-
tion, the “OFF” portion of the symbol stamped on the switch will not illu-
minate in the dark. Only “VDC” portion will illuminate.
Pressing the VDC OFF switch to deactivate the VDC system can facilitate the following operations: a standing start on a steeply sloping road with a snowy, gravel-cov-
ered, or otherwise slippery surface extrication of the vehicle when its wheels are stuck in mud or deep
snow
When the VDC OFF switch is pressed during engine operation, the VDCOFF indicator light illuminates.The VDC system will be deactivated and the vehicle will behave like a
model not equipped with the VDC system.
When the VDC OFF switch is pressed again to reactivate the VDC sys-
tem, the VDC OFF indicator light goes off.
If the vehicle reaches a speed of approximately 37 mph (60 km/h) after
the VDC OFF switch is pressed to deactivate the VDC system, the VDC
system automatically reactivates itself and the VDC OFF indicator light
goes off. While the vehicle is moving at a speed of approximately 37
mph (60 km/h) or higher, it is not possible to deactivate the VDC system
by pressing the VDC OFF switch.
With the VDC system deactivated, traction and stability enhancement of-
fered by VDC system is unavailable. Therefore you should not deactivate

When parking on a hill, always turn the steering wheel. When the vehicle
is headed up the hill, the front wheels should be turned away from the
curb. When facing downhill, the front wheels should be turned into thecurb.
Cruise control (if equipped)
WARNING
Do not use the cruise control under any of the following condi- tions. This may cause loss of vehicle control: driving up or down a steep grade
driving on slippery or winding roads
driving in heavy traffic
Cruise control enables you to maintain a constant vehicle speed without
holding your foot on the accelerator pedal and it is operative when the
vehicle speed is 25 mph (40 km/h) or more. Make sure the main switch is
turned “OFF” when the cruise control is not in use to avoid unintentionally
by setting the cruise control.

To set cruise control
HG0312
HB3002BB
Cruise control lever
1. Push the “CRUISE” main switch. The indicator light on the switch
will come on.
2. Depress the accelerator pedal until the vehicle reaches the de-
sired speed.
3. Push the control lever downward in the “SET, COAST ” direction
and release it. Then release the accelerator pedal.
The vehicle will maintain the desired speed.
Vehicle speed can be temporarily increased while driving with the
cruise control activated. Simply depress the accelerator pedal to ac-
celerate the vehicle. When the accelerator pedal is released, the ve-
hicle will return to and maintain the previous cruising speed. To temporarily cancel the cruise control
There are four ways to cancel the cruise control temporarily:
Depress the brake pedal.
Pull the control lever in the “CANCEL” direction. (if so equipped)
Depress the clutch pedal (manual transmission vehicles only).
Shift the selector lever into the “N” position (automatic transmis-
sion vehicles only).
To resume the cruise control after it has been temporarily canceled
and with vehicle speed of about 20 mph (32 km/h) or more, push the
control lever upward in the “ACCEL, RESUME ” direction to return to
the original cruising speed automatically.

7-46
To turn off the cruise control
There are two ways to turn off the cruise control: Push the main switch again.
Turn the ignition switch to the “ACC” position (but only when the
vehicle is completely stopped).
To change the cruising speed
n To increase the speed (by control lever)
Push the control lever upward in the “ACCEL, RESUME ” direction and
hold it until the vehicle reaches the desired speed. Then, release the
control lever. The vehicle speed at that moment will be memorized
and treated as the new set speed.
When the difference between the actual vehicle speed and the set
speed is less than 4 mph (6.8 km/h), the set speed can be increased
1 mph (1.6 km/h) each time by pressing the control lever upward inthe “ACCEL, RESUME ” direction quickly within a half second.
n To increase the speed (by accelerator pedal)
1. Depress the accelerator pedal to accelerate the vehicle to the de-
sired speed.
2. Push the control lever downward in the “SET, COAST ” direction
once. Now the desired speed is set and the vehicle will keep running
at that speed without depressing the accelerator pedal.
NOTE If the difference between the actual vehicle speed when the con- trol lever is pushed downward and the speed last time you set is
less than 4 mph (6.8 km/h), the vehicle speed will be lowered by 1mph (1.6 km/h). This occurs because the cruise control systemunit regards this lever operation as that intended to decrease the
vehicle speed. n To decrease the speed (by control lever)
Push the control lever downward in the “SET, COAST ” direction and
hold it until the vehicle reaches the desired speed. Then, release the
control lever. The vehicle speed at that moment will be memorized
and treated as the new set speed.

speed is less than 4 mph (6.8 km/h), the set speed can be lowered 1
mph (1.6 km/h) each time by pressing the control lever downward inthe
“SET, COAST ” direction quickly within a half second.
n To decrease the speed (by brake pedal)
1. Depress the brake pedal to release cruise control temporarily.
2. When the speed decreases to the desired speed, press the control
lever downward in the “SET, COAST ” direction once. Now the desired
speed is set and the vehicle will keep running at that speed without
depressing the accelerator pedal.
