WARNING
Do not drive the vehicle with the selector lever in the “N” (neutral) position. Engine braking
has no effect in this condition and the risk ofan accident is consequently increased.
D (Drive)
This position is for normal driving.The transmission automatically shifts into a suitable
gear from 1st to 4th according to the vehicle speed
and the acceleration you require.
When more acceleration is required in this position,
press the accelerator pedal fully to the floor andhold that position. The transmission will automatical-
ly downshift to 3rd, 2nd or 1st gear. When you re-
lease the pedal, the transmission will return to the
original gear position.
n While climbing a grade
When driving up hill, undesired upshift to 4th gear is
prevented from taking place when the accelerator
pedal is released. This minimizes the chances of subsequent downshifting to a lower gear when ac-
celerating again. This prevents repeated upshifting
and downshifting resulting in a smoother operation of the vehicle.
NOTE The transmission may downshift to 2nd or 1st
gear, depending on the way the accelerator pedalis pressed to accelerate the vehicle again. n While going down a hill
When descending a steep hill, depressing the brake
pedal will cause the transmission to downshift to 3rd
gear, thus applying engine braking. Reacceleration
for a short time will cause the transmission to upshift
normally. NOTE In some cases, depressing the brake pedal on a downhill grade does not result in an automatic
downshift to 3rd gear. This can happen when theautomatic transmission fluid temperature is very
low, for example, during driving shortly after the
vehicle has been parked for an extended period
of time. When the ATF temperature has risen to a
certain level, automatic downshift normally takes
place. In the meantime, downshift manually forengine braking as required.Also, downshifting when braking downhill willnot occur at speeds above approximately 48 mph(78 km/h).

NOTE
In order to prevent over-revving during decelera-
tion of the vehicle, the transmission will remain
in the current gear if the speed of the vehicle isin excess of the Maximum Allowable Speed for
the gear to which the selector lever has beenmoved.
WARNING
When shifting down a gear, ensure that the
vehicle is not travelling at a speed exceeding the Maximum Allowable Speed for the gear which is about to be selected. Failure toobserve this precaution can lead to engine
over-revving and this in turn can result inengine damage.In addition, sudden application of engine
brakes when the vehicle is travelling on a slip- pery surface can lead to wheel locking; as a
consequence, control of the vehicle may belost and the risk of an accident increased.
Driving tips
Always apply the foot or parking brake when the
vehicle is stopped in the “D”, “3”, “2”, “1” or “R”
position. Always set the parking brake when parking your
vehicle. Do not hold the vehicle with only the trans-mission. Do not keep the vehicle in a stationary position on
an uphill grade by using the “D”, “3”, “2”, or “1”
position. Use the brake instead.
The engine may, on rare occasions, knock when the
vehicle rapidly accelerates or rapidly pulls away
from a standstill. This phenomenon does not indi-
cate a fault.
Shift lock release
If the selector lever does not move from the “P” posi-
tion with the brake pedal depressed and the ignitionswitch in the “ON” position, perform the following
steps:
To override the shift lock:
1. Set the parking brake and stop the engine.
2. Take out the screwdriver from the tool bag.
3. Remove the cover by prying on the edge with the
regular screwdriver.

Braking Braking tips
WARNING
Never rest your foot on the brake pedal while driving. This can cause dangerous overheat- ing of the brakes and needless wear on thebrake pads and linings.
When the brakes get wet
When driving in rain or after washing the vehicle, the
brakes may get wet. As a result, brake stopping dis-
tance will be longer. To dry the brakes, drive the ve-
hicle at a safe speed while lightly depressing thebrake pedal to heat up the brakes.
Use of engine braking
Remember to make use of engine braking in addi-
tion to foot braking. When descending a grade, if
only the foot brake is used, the brakes may start
working improperly because of brake fluid overheat-
ing, caused by overheated brake pads. To help pre-
vent this, shift into a lower gear to get stronger
engine braking.
Braking when a tire is punctured
Do not depress the brake pedal suddenly when a
tire is punctured. This could cause a loss of controlof the vehicle. Keep driving straight ahead while
gradually reducing speed. Then slowly pull off the
road to a safe place. Brake system
Two separate circuits
Your vehicle has two separate circuit brake systems.
Each circuit works diagonally across the vehicle. If
one circuit of the brake system should fail, the other
half of the system still works. If one circuit fails, thebrake pedal will go down much closer to the floor
than usual and you will need to press it down much
harder. And a much longer distance will be needed to stop the vehicle.
Brake booster
The brake booster uses engine manifold vacuum to
assist braking force. Do not turn off the engine while
driving because that will turn off the brake booster,
resulting in poor braking power. The brakes will continue to work even when the brake booster completely stops functioning. If this
happens, however, you will have to push the pedal

much harder than normal and the braking distance
will increase. Disc brake pad wear warning indica- tors
The disc brake pad wear warning indicators on the
disc brakes give a warning noise when the brake
pads are worn.
If a squeaking or scraping noise is heard from the disc brakes while braking, immediately have your
vehicle checked by your SUBARU dealer. ABS (Anti-lock Brake 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 wheel lock-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 ABS operates. The ABS system will not operate when the vehicle
speed is below approximately 6 mph (10 km/h).
WARNING
Always use the utmost care in driving
– over-
confidence because you are driving with an
ABS equipped vehicle could easily lead to aserious accident.

Starting and operating
7-24
CAUTION
The ABS system does not always decrease
stopping distance. You should always main- tain a safe following distance from other ve- hicles. When driving on badly surfaced roads, grav-
el roads, icy roads, or over deep newly fallen
snow, stopping distances may be longer for a
vehicle with the ABS system than one without. When driving under these conditions, there-
fore, reduce your speed and leave ample dis-tance from other vehicles. 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.
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 iscaused by an automatic functional test of the ABS
system being carried out and does not indicate any
abnormal condition.
ABS warning light
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.
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 lightwill go out.

CAUTION
If the warning light behaves as follows, the
ABS system may not be working properly. When the warning light is on, the ABS func-
tion shuts down; however, the conventional
brake system continues to operate normally.The warning light does not come on when
the ignition switch is turned to the “ON” posi-
tion. The warning light comes on when the igni-
tion switch is turned to the “ON” position, but
it does not go out even when the vehicle speed exceeds approximately 8 mph (12km/h). The warning light comes on during driving.
If these occur, have the ABS system repairedat the first available opportunity by your
SUBARU dealer.
NOTE If the warning light behavior is as described
below, the ABS system may be considered nor- mal. 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 8 mph (12 km/h). The warning light comes on during driving, but
it goes out immediately and remains off.

Parking your vehicle Parking brake
To set the parking brake, press the brake pedal firm- ly and hold it down while fully pulling up the parking
brake lever.
To release the parking brake, pull the lever up slight-
ly, press the release button, then lower the lever
while keeping the button pressed.
When the parking brake is set while the engine is
running, 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 (chap-
ter 3).
CAUTION
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 ful-ly 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 parking brake firmly when parking your ve-
hicle. Never rely on the transmission alone to holdthe vehicle.

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 the curb.
WARNING
Never leave unattended children or pets in
the vehicle. They could accidentally injure
themselves or others through inadvertent op-
eration of the vehicle. Also, on hot or sunny
days, the temperature in a closed vehiclecould quickly become high enough to cause
severe or possibly fatal injuries to people. Do not park the vehicle over flammable ma-
terials such as dry grass, waste paper or rags,

as they may burn easily if they come near hot engine or exhaust system parts.Be sure to stop the engine if you take a nap
in the vehicle. If engine exhaust gas enters the
passenger compartment, occupants in the ve-hicle could die from carbon monoxide (CO) contained in the exhaust gas.
CAUTION
If your vehicle has a front underspoiler and rear underspoiler (both optional), pay atten- tion to blocks and other obstructions on the ground when parking. The underspoilerscould be damaged by contact with them. Cruise control (if equipped)
Cruise control enables you to maintain a constant
vehicle speed without holding your foot on the ac-
celerator 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.WARNING
Do not use the cruise control under any of the following conditions. This may cause loss of
vehicle control: driving up or down a steep grade
driving on slippery or winding roads
driving in heavy traffic

Engine exhaust gas (Carbon monoxide)
WARNING
Never inhale engine exhaust gas. Engine ex-
haust gas contains carbon monoxide, a color-
less and odorless gas which is dangerous, or even lethal, if inhaled. Always properly maintain the engine ex-
haust system to prevent engine exhaust gasfrom entering the vehicle. Never run the engine in a closed space,
such as a garage, except for the brief time needed to drive the vehicle in or out of it. Avoid remaining in a parked vehicle for a
lengthy time while the engine is running. Ifthat is unavoidable, then use the ventilationfan to force fresh air into the vehicle. Always keep the front ventilator inlet grille
free from snow, leaves or other obstructionsto ensure that the ventilation system always
works properly. If at any time you suspect that exhaust
fumes are entering the vehicle, have the prob-lem checked and corrected as soon as pos- sible. If you must drive under these condi-tions, drive only with all windows fully open.
Keep the trunk lid or rear gate closed while
driving to prevent exhaust gas from enteringthe vehicle.
NOTE Due to the expansion and contraction of the met-
als used in the manufacture of the exhaust sys-
tem, you may hear a crackling sound comingfrom the exhaust system for a short time afterthe engine has been shut off. This sound is nor-mal.
