7-2. State Emission Testing (U.S. Only)California and a number of federal states

have Inspection/Maintenance programs
to inspect your vehicle’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed to
detect engine and transmission problems
that might cause the vehicle emissions to
exceed allowable limits. OBDII inspec-
tions apply to all 1996 model year and
newer passenger cars and trucks. Over
30 states plus the District of Columbia
Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank could
cause damage to the engine.
Continuing to operate your
vehicle at an extremely low fuel
level may result in a reduction of
engine performance.

CAUTION
Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of the
state inspection program or its con-
tractors or licensees.

2341) Slider3. To shift into the “R” position, hold up
the slider, move the lever to the “R” posi-
tion, then release the slider.
4. Gradually release 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.
■ Shifting Speeds▼ Recommended shifting speeds
The best compromise between fuel
economy and vehicle performance during
normal driving is ensured by shifting up at
the speeds listed in the following table. ▼
Gear shift indicator
1) Upshift indicator
2) Gear position indicatorThe gear position indicator shows the
position of the shift lever.
When shifting up is recommended for
good fuel economy, the upshift indicator
blinks.
The gear shift indicator can be activated
or deactivated. The default setting is
deactivated. For details, refer to "Settings
Display" P157.
WARNING
 Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral posi-
tion. Engine braking has no effect
in either of these conditions and
the risk of an accident is conse-
quently increased.
1702835
 Do not engage the clutch (i.e.,
release the clutch pedal)
suddenly when starting the
vehicle. By doin g so the vehicle
might unexpectedly accelerate or
the transmission could malfunc-
tion.
CAUTION
 Shift into reverse ONLY when the
vehicle has completely stopped.
It may cause damage to the trans-
mission to try shifting into
reverse when the vehicle is
moving. Do not shift the shift lever without
depressing the clutch pedal.

■Driving TipsNOTEIf the accelerator and brake pedals are
depressed at the same time, driving
torque may be restrained. This is not a
malfunction.
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to
hold your vehicle at a standstill on an
upgrade. Either of those actions may
cause clutch damage.
Do not drive with your hand resting on the
shift lever. This may cause wear on the
transmission components. 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
labor.
On steep downgrades, downshift the
transmission to 5th, 4th, 3rd or 2nd gear
as necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you “ride” (over use)
the brakes while descending a hill, they
may overheat and not work properly.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle.
With the exception of cases where sudden
acceleration is required, do not drive the
vehicle with the pointer of the tachometer
inside the red area. Failure to observe this
precaution can lead to excessive engine
wear and poor fuel economy.
7-6. Automatic TransmissionThe automatic transmission is electroni-
cally controlled and provides 6 forward
speeds and 1 reverse speed. It also has a
manual mode.
WARNING
When shifting down a gear, ensure
that the engine speed does not
enter the red zone. Failure to
observe this precaution can lead to
engine over-revving and this in turn
can result in engine damage.In addition, sudden application of
engine brakes when the vehicle is
travelling on a slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident
increased.
WARNING
Do not shift from the “P” or “N”
position into the “D” or “R” position
while depressing the accelerator
pedal. This may cause the vehicle to
lurch forward or backward.
CAUTION
 Observe the following precau-
tions. Failure to observe these
precautions could cause damage
to the transmission.
- Shift into the “P” or “R” posi- tion only after the vehicle has
completely stopped.- Do not shift from the “D” posi- tion into the “R” position or
vice versa until the vehicle
has completely stopped.

Automatic Transmission
236NOTEWhen the engine coolant tempera-
ture is still low, the transmission will
shift at higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automatically shift to the normal
timing after the
engine has warmed up.
 Immediately after transmission fluid
is replaced, you may feel that the trans-
mission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
 Place the shift boot to the original
position after it is lifted. If the shift lever
is operated with the shift boot in the
rolled up position, the shift boot may
have tension and it may disturb the
shift lever operation.
 When the vehicle is idling at high
rpm in order to warm up, and the
vehicle is on a slippery road, the trans-
mission may automatically shift to 2nd
gear for stopping and starting off.
■ Select Lever
: Shift with the brake pedal depressed
and push-button ignition switch in the “ON”
position. When shifting between “P” and “D”,
depress the brake pedal and securely stop
the vehicle before shifting.
The select lever has four positions, “P”,
“R”, “N”, “D” and also has a manual gate
for using the manual mode.NOTETo protect the engine while the select
lever is in the “P” or “N” position, the
engine is controlled so that the engine
speed may not become too high even
if the accelerator pedal is depressed
hard.
 Do not race the engine for more
than 5 seconds in any position
except the “N” or “P” position
when the brake is applied or when
chocks are used in the wheels.
This may cause the transmission
fluid to overheat. Never move the vehicle rearward
by inertia with the select lever set
in a forward driving position or
move the vehicle forward by
inertia with the select lever set in
the “R” position. Doing so may
result in an unexpected accident
or malfunction. When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the “P” position. Do not park for a
long time with the select lever in
any other position as doing so
could result in a dead battery.
