Odometer/Trip meter
1) Trip meter
2) Odometer
This meter displays the odometer and two
trip meters when the ignition switch is in
the “LOCK ”, “ACC ” or “ON ” position.
If you press the trip knob when the ignition
switch is in the “LOCK ” position, the
odometer/trip meter will light up. It is pos-
sible switch between the A trip meter and
B trip meter indications while the odome-
ter/trip meter is lit up. If you do not press
the trip knob within 10 seconds of illumina-
tion of the odometer/trip meter, the odom-
eter/trip meter will go off.
Odometer
The odometer shows the total distance that the vehicle has been driven.
Double trip meter
The trip meter shows the distance that the
vehicle has been driven since you last set
it to zero.
To change the mode indication, briefly
push the knob.
Each press of the knob changes the func-
tion alternately.
To set the trip meter to zero, select the A
trip or B trip meter by pushing the knob
and keep the knob pushed for more than
2 seconds.
NOTE
If the connection between the combi-
nation meter and battery is broken for
any reason such as vehicle mainte-
nance or fuse replacement, the data re-
corded on the trip meter will be lost.
Tachometer
The tachometer shows the engine speed
in thousands of revolutions per minute.

A trip meter B trip meter
To ensure safety, do not attempt to
change the function of the indicator
during driving, as an accident could
result.
Do not operate the engine with the
pointer of the tachometer in the red
zone. In this range, fuel injection will
be cut by the engine control module
to protect the engine from overrev-
ving. The engine will resume run-
ning normally after the engine
speed is reduced below the red
zone.

NOTE
If the connection between the combi-
nation meter and battery is broken for
any reason such as vehicle mainte-
nance or fuse replacement, the data re-
corded on the trip meter will be lost.
Tachometer
The tachometer shows the engine speed
in thousands of revolutions per minute.
Fuel gauge
1) Low fuel warning light
The fuel gauge shows the approximate
amount of fuel remaining in the tank.
The gauge does not return to “E ” even
though the ignition switch is in the “ACC ”
or “LOCK ” position.
The gauge may move slightly during brak-
ing, turning or acceleration due to fuel lev-
el movement in the tank.
NOTE
You will see the “FUEL DOOR ”
sign near the fuel gauge.
This indicates that the fuel filler door
(lid) is located on the right side of the
vehicle.
Low fuel warning light
The low fuel warning light comes on when
the tank is nearly empty [approximately
2.3 US gal (9.0 liters, 1.9 Imp gal]. It only
operates when the ignition switch is in the“ ON ” position.
NOTE
This light does not go out unless the
tank is replenished up to an internal
fuel quantity of approximately 4.0 US
gal (15 liters, 3.3 Imp gal).
To ensure safety, do not attempt to
change the function of the indicator
during driving, as an accident could
result.
Do not operate the engine with the
pointer of the tachometer in the red
zone. In this range, fuel injection will
be cut by the engine control module
to protect the engine from overrev-
ving. The engine will resume run-
ning normally after the engine
speed is reduced below the red
zone.

Maintenance and serviceMaintenance schedule
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the “Warranty and Mainte-
nance Booklet ”.
For details of your maintenance schedule,
read the separate “Warranty and Mainte-
nance Booklet ”.
Maintenance precautions
When maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service
by yourself, you should familiarize your-
self with the information provided in this
section on general maintenance and ser-
vice for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
Testing of an All-Wheel Drive ve-
hicle must NEVER be performed
on a single two-wheel dynamome-
ter or similar apparatus. Attempt-
ing to do so will result in transmis-
sion damage and in uncontrolled
vehicle movement and may cause
an accident or injuries to persons
nearby.
Always select a safe area when
performing maintenance on your
vehicle.
Always be very careful to avoid in-
jury when working on the vehicle.
Remember that some of the mate-
rials in the vehicle may be hazard-
ous if improperly used or handled,
for example, battery acid.
Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
Always use the proper tools and
make certain that they are well
maintained.
Never get under the vehicle sup-
ported only by a jack. Always use
a safety stands to support the ve-
hicle.
Never keep the engine running in
a poorly ventilated area, such as a
garage or other closed areas.
Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only by
your SUBARU dealer.
