Starting the engine
CAUTION
Do not operate the starter motor continuously
for more than ten seconds. If the engine fails to start after operating the starter for five to ten seconds, wait for ten seconds or more be-fore trying again.
Starting the engine for a manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Press the clutch pedal to the floor and shift the
shift lever into neutral. Hold the clutch pedal to the
floor while starting the engine.
The starter motor will only operate when the clutch
pedal is pressed fully to the floor.
4. Turn the ignition switch to the “ON” position and
check the operation of the warning and indicatorlights. Refer to the “Warning and indicator light ” sec-
tion (chapter 3).
5. Turn the ignition switch to the “START” position
without depressing the accelerator pedal. Release the key immediately after the engine has started.
If the engine does not start within ten seconds, wait
a while and then turn the ignition switch to the
“START”
position again while depressing the accel-
erator pedal half way down.
6. Confirm that all warning and indicator lights have
gone off after the engine has started. The fuel injec-
tion system automatically lowers the idle speed as
the engine warms up.
Starting the engine for an automatic transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Shift the selector lever to the “P” or “N” position
(preferably “P” position).

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
HG1016FA
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 light will go out.

Driving tips

it more prone to tip over. If you must rock the vehicle to free it from sand or
mud, depress the accelerator pedal slightly and
move the selector lever back and forth between “D”
and “R” repeatedly. Do not race the engine. For the
best possible traction, avoid spinning the wheels
when trying to free the vehicle.
When the road surface is extremely slippery, you
can obtain better traction by starting the vehicle withthe transmission in 2nd than 1st (both for MT and
AT). Never equip your vehicle with tires larger than
those specified in this manual. Frequent driving of an AWD vehicle under hard-
driving conditions such as rough roads or off roads
will necessitate more frequent replacement of engine
oil, brake fluid and transmission oil than that specified
in the maintenance schedule described in the “War -
ranty and Maintenance Booklet ”.
Remember that damage done to your Subaru while
operating it off-road and not using common sense
precautions such as those listed above is not eligi-ble for warranty coverage. Winter driving
HG8001AA

Operation during cold weather
Carry some emergency equipment, such as tire
chains, a window scraper, a bag of sand, flares, asmall shovel, and jumper cables.
Check the battery and cables. Cold temperatures
reduce battery capacity. The battery must be in
good condition to provide enough power for cold
winter starts.
Use an engine oil of proper grade and viscosity for
cold weather. Heavy summer oil will cause harder
starting.

Brake booster If the brake booster does not operate as described
below, have it checked by your SUBARU dealer.
1. With the engine off, depress the brake pedal sev-
eral times, applying the same pedal force each time.
The distance the pedal travels should not vary.
2. With the brake pedal depressed, start the en-
gine. The pedal should move slightly down to the
floor.
3. With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds. The pedal height should not change.
4. Start the engine again and run for about one min-
ute then turn it off. Depress the brake pedal several
times to check the brake booster. Brake booster op-
erates properly if the pedal stroke decreases with
each depression. Brake pedal
Check the brake pedal free play and reserve dis-
tance according to the maintenance schedule in the“
Warranty and Maintenance Booklet ”).
