The key can be turned from “ACC” to “LOCK” only
when the key is pushed in while turning it.
WARNING
Never turn the ignition switch to “LOCK”
while the vehicle is being driven or towed be-
cause that will lock the steering wheel, pre-venting steering control. And when the engine is turned off, it takes a much greater effort
than usual to steer.

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.
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. Automatic transmission vehicle

Stopping the engine
The ignition switch should be turned off only when the engine is idling.
WARNING
Do not stop the engine when the vehicle is moving. This will cause loss of power to the
power steering and the brake booster, makingsteering and braking more difficult. It could also result in accidental activation of the
“LOCK” position on the ignition switch, caus-
ing the steering wheel to lock. Manual transmission
The manual transmission is a fully synchromeshed
5-forward and 1-reverse speed transmission.
The shift pattern is shown on the shift lever knob.
When shifting from 5th gear to reverse gear, first re-
turn the shift lever to the neutral position then shift
into reverse gear.
To change gears, fully depress the clutch pedal,
move the shift lever, and gradually let up on the
clutch pedal.
If it is difficult to shift into gear, put the transmission

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).

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.

To temporarily cancel the cruise con- trol
There are four ways to cancel the cruise control tem- porarily: 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 (auto-
matic transmission vehicles only).
To resume the cruise control after it has been tem- porarily 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.
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” or “LOCK”
position (but only when the vehicle is completely stopped).
To change the cruising speed
To increase the speed (by control lever)
Push the control lever upward in the “ACCEL, RE-
SUME” direction and hold it until the vehicle reaches
the desired speed. Then, release the control lever.
The vehicle speed at that moment will be memo-
rized 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 up-
ward in the “ACCEL, RESUME ” direction quickly
within 0.5 second.
To increase the speed (by accelerator pedal)
1. Depress the accelerator pedal to accelerate the
vehicle to the desired 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 control lever is pushed down-ward and the speed last time you set is less than

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

Operation during cold weather
Carry some emergency equipment, such as tire
chains, a window scraper, a bag of sand, flares, a small 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

safety’s sake, you should employ extra cau-
tion when towing a trailer and you should
never speed. You should also keep the follow-ing tips in mind:
Before starting out on a trip
Check that the vehicle and vehicle-to-hitch mount-
ing are in good condition. If any problems are
apparent, do not tow the trailer. Check that the vehicle sits horizontally with the
trailer attached. If the vehicle is tipped sharply up at
the front and down at the rear, check the total trailer
weight, GVW, GAWs and tongue load again, then
confirm that the load and its distribution are accept-able. Check that the tire pressures are correct.
Check that the vehicle and trailer are connected
properly. Confirm that
–the trailer tongue is connected properly to the
hitch ball.– the trailer lights connector is connected prop-
erly and trailer ’s brake lights illuminate when the
vehicle’ s brake pedal is pressed, and that the trail-
er’ s turn signal lights flash when the vehicle ’s turn
signal lever is operated.– the safety chains are connected properly. –
all cargo in the trailer is secured safety in posi-
tion.– the side mirrors provide a good rearward field of
view without a significant blind spot.
Sufficient time should be taken to learn the “feel”
of the vehicle/trailer combination before starting out
on a trip. In an area free of traffic, practice turning, stopping and backing up.
Driving with a trailer
You should allow for considerably more stopping
distance when towing a trailer. Avoid sudden brak-
ing because it may result in skidding or jackknifing
and loss of control. Avoid abrupt starts and sudden accelerations. If
your vehicle has a manual transmission, always start
out in first gear and release the clutch at moderate
engine revolution. Avoid uneven steering, sharp turns and rapid lane
changes. Slow down before turning. Make a longer than
normal turning radius because the trailer wheels will
be closer than the vehicle wheels to the inside of the
turn. In a tight turn, the trailer could hit your vehicle. Crosswinds will adversely affect the handling of
your vehicle and trailer, causing sway. Crosswindscan be due to weather conditions or the passing of

Driving tips
8-38
If your vehicle has an automatic transmission,
avoid using the accelerator pedal to stay stationary on an uphill slope instead of using the parking brakeor foot brake. That may cause the transmission fluid
to overheat. Also, if your vehicle is equipped with an
automatic transmission, avoid driving with the gear selector lever in “D” when towing a heavy trailer to
prevent fluid overheating. A lower gear should be used.
Parking on a grade
Always block the wheels under both vehicle and
trailer when parking. Apply the parking brake firmly.
You should not park on a hill or slope. But if parking on a hill or slope cannot be avoided, you shouldtake the following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under boththe vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb theload.
4. Apply the regular brakes and then apply the
parking brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmis- sion) or “P” (automatic transmission) and shut off the
engine.
