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).
The starter motor will only operate when the select lever is at the “P” or “N” position.
4. Turn the ignition switch to the “ON” position and
check the operation of the warning and indicator lights. Refer to the “Warning and indicator lights ”
section (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

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.
OM-H2241
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
in neutral, release the clutch pedal momentarily, and
then try again.

WARNING
Do not drive the vehicle with the clutch disen- gaged (i.e., when the clutch pedal is
depressed) or with the shift lever in the neu-tral position. Engine braking has no effect in either of these conditions and the risk of an
accident is consequently increased.
CAUTION
Shift into reverse ONLY when the vehicle has
completely stopped. It may cause damage to the transmission to try shifting into reversewhen the vehicle is moving.
Shifting speeds
Recommended shifting speeds
The best compromise between fuel economy and
vehicle performance during normal driving is en-
sured by shifting up at the speeds listed in the fol-lowing table. Shift up
mph (km/h)
1st to 2nd15 (24)
2nd to 3rd25 (40)
3rd to 4th40 (65)
4th to 5th45 (73)

Maximum allowable speeds
The following table shows the maximum speeds that
are possible with each different gear. Never exceed the speed limit below for each gear
position except for brief acceleration in an emergen-
cy. The tachometer ’s needle (if so equipped) will en-
ter the red area if these speeds are exceeded. Fail-
ure to observe this precaution can lead to excessive
engine wear and poor fuel economy.

WARNING
When shifting down a gear, ensure that the
vehicle is not travelling at a speed exceedingthe Maximum Allowable Speed for the gearwhich is about to be selected. Failure to observe 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 be lost and the risk of an accident increased.
Driving tips
Do not drive with your foot resting on the clutch ped- al and do not use the clutch to hold your vehicle at a standstill on an upgrade. Either of those actions maycause clutch damage.
Do not drive with your hand resting on the shift lever.This may cause wear on the transmission compo-nents.
When it is necessary to reduce vehicle speed due to
slow traffic, turning corners, or driving up steep hills,
downshift to a lower gear before the engine starts to

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 de-
press the accelerator pedal to accelerate the ve-
hicle. When the accelerator pedal is released, the
vehicle will return to and maintain the previous cruis-ing speed.
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
1. Push the control lever upward in the “ACCEL, RE-
SUME” direction and hold it until the vehicle reaches

Driving tips
8-36
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
large trucks or buses. If swaying occurs, firmly grip the steering wheel and slow down immediately but
gradually. When passing other vehicles, considerable dis-
tance is required because of the added weight and
length caused by attaching the trailer to yourvehicle. Backing up with a trailer is difficult and takes
practice. 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.
OM-H2791
1) Left turn 2) Right turn
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 dealer.
Driving on grades
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
overheating of your vehicle ’s brakes. Do not make
