▽Garage Door Two-Way Commu -
nication
HomeLink® has the capability of commu-
nicating with your garage door opener.
HomeLink® can receive and display
“closing” or “opening” status messages
from compatible garage door opener
systems. At any time, HomeLink
® can
also recall and display the last recorded
status communicated by the garage door
opener to indicate your garage door being
“closed” or “opened”. HomeLink
® has the capability of receiving

this communication from the garage door
opener at a range up to 820 feet (250 m).
Range may be reduced by obstacles such
as houses or trees. You may have to slow
your vehicle speed to successfully receive
the garage door opener communication.
▽Programming Two-Way
Communication
1) Status IndicatorsWithin 5 seconds after programming a
new HomeLink
® button, both of
HomeLink’s garage door status indicators
will flash rapidly green indicating that the
garage door two-way communication has
been enabled. If your garage door status
indicators flashed, two-way communica-
tion programming is complete.

Fuel
2266. Stop filling the tank after the fuel filler
pump automatically stops. Do not add any
more fuel.
7. Put the cap back on and turn it clock-
wise until you hear a clicking noise. Be
certain not to catch the tether under the
cap while tightening.
8. Close the fuel filler lid completely.
NOTE You will see the “ ” sign in the
fuel gauge. This indicates that the fuel
filler lid is located on the right side of
the vehicle.
 If the fuel filler cap is not tightened
until it clicks or if the tether is caught
under the cap, the CHECK ENGINE
warning light/malfunction indicator
light may illuminate. Refer to "CHECK
ENGINE Warning Light/Malfunction
Indicator Light" P136.
 To lock the fuel filler lid, perform one
of the operations below. However if
these operations are performed when
the fuel filler lid is open, the fuel filler
lid will not lock when it is subsequently
closed. - Press the “ ” button on the key
fob.
- Press the lock side of the power
door locking switch.
WARNING
 When refueling, insert the fuel
nozzle securely into the fuel filler
pipe. If the nozzle is lifted or not
fully inserted, its automatic stop-
ping mechanism may not func-
tion, causing fuel to overflow the
tank and creating a fire hazard. Stop refueling when the auto-
matic stop mechanism on the fuel
nozzle activates. If you continue
to add fuel, temperature changes
or other conditions may cause
fuel to overflow from the tank and
create a fire hazard.
CAUTION
Make sure that the cap is tightened
until it clicks to prevent fuel spillage
in the event of an accident.
CAUTION
Do not let fuel sp ill on the exterior
surfaces of the vehicle. Because
fuel may damage th e paint, be sure
to wipe off any spilled fuel quickly.
Paint damage caused by spilled fuel
is not covered under the SUBARU
Limited Warranty.
CAUTION
 Never add any cleaning agents to
the fuel tank. Th e addition of a
cleaning agent may cause
damage to the fuel system. After refuelin g, turn the cap to the
right until it clicks to ensure that it
is fully tightened. If the cap is not
securely tightened, fuel may leak
out while the vehicle is being
driven or fuel spillage could
occur in the event of an accident,
creating a fire hazard. Do not let fuel spill on the exterior
surfaces of the vehicle. Because
fuel may damage the paint, be
sure to wipe off any spilled fuel
quickly. Paint damage caused by
spilled fuel is not covered under
the SUBARU Limited Warranty. Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit or have
proper venting and your fuel tank
and emission control system may
be damaged. It could also lead to
fuel spillage and a fire.

Starting and Stopping Engine
230On rare occasions, it may be difficult
to start the engine depending on the
fuel and the usage condition (repeated
driving of a distance in which the
engine has not warmed up suffi-
ciently). In such a case, it is recom-
mended that you change to a different
brand of fuel.
 On rare occasions, transient
knocking may be heard from the
engine when the accelerator is oper-
ated rapidly such as a rapid start-up
and a rapid acceleration. This is not a
malfunction.
 The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.■ Starting Engine
NOTEWhen pressing the push-button
ignition switch while depressing the
clutch pedal (MT models) or the brake
pedal (AT models): - The engine starter operates for a
maximum of 10 seconds and after
starting the engine, the starter stops
automatically.
- The engine can be started
regardless of the power status.
 If the engine does not start, check
the security indicator light. Then press
the push-button ignition switch
without depressing the clutch pedal
(MT models) or the brake pedal (AT
models) to switch the power to “OFF”. - If the light had illuminated, try to
start the engine again.
- If the light had been off, press the
push-button ignition switch while
depressing the clutch pedal (MT
models) or the brake pedal (AT
models) more forcefully.
 The engine start procedures may
not function depending on the radio
wave conditions around the vehicle. In
such a case, refer to "Starting Engine"
 P326.
 If the vehicle battery is discharged,
the steering cannot be unlocked.
Charge the battery.
WARNING
 There are some general precau-
tions when starting the engine.
Carefully read the precautions
described in "General Precau-
tions When Starting Engine"
 P229. If the steering lock cannot be
released after the engine has
started, never drive the vehicle.
The steering is still locked, and it
may result in an accident.
CAUTION
 If a system malfunction warning
message is displayed on the
combination meter, there may be
a malfunction with the vehicle.
Contact a SUBARU dealer imme-
diately. If a steering lock warning
message is displayed on the
combination me ter after the
engine has started, it means that
the steering is still locked. While
moving the steering wheel right
and left, depress the brake pedal,
and press the push-button igni-
tion switch. Do not continue pressing the
push-button ignition switch for
more than 10 seconds. Doing so
could cause a malfunction. If the
engine does not start, stop
pressing the push -button ignition
switch. Instead, press the push-
button ignition switch without
depressing the clutch pedal (MT
models) or the brake pedal (AT
models) to switch the power
status to “OFF”. Wait 10 seconds,
and then press the push-button
ignition switch to start the
engine.

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.
