&Replacing the battery
CAUTION
. Do not let dust, oil or water get on
or in the transmitter when repla-
cing the battery.
. Be careful not to damage the
printed circuit board in the trans-
mitter when replacing the battery.
. Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
. There is a danger of explosion if
an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
When the transmitter battery begins to get
weak, transmitter range will begin to
decrease. Replace the battery as soon
as possible. To replace the battery:
1. Open the transmitter case using a flat-
head screwdriver.
2. Remove the old battery from the
holder.
1) Negative (
) side facing up
3. Replace with a new battery (type CR2025 or equivalent) making sure to
install the new battery with the negative( ) side facing up.
4. Refit the removed half of the transmit-
ter case.
After the battery is replaced, the trans-
mitter must be synchronized with the
remote keyless entry system ’s control
unit. Press either the “
”or “”button
six times to synchronize the unit. & Replacing lost transmitters

may not operate properly if some
object gets trapped just before
the window fully closes. NOTE .
If a window detects an impact simi-
lar to that caused by trapping an object
(for example, when the vehicle encoun-
ters a deep pothole), the anti-entrap-
ment function may operate.. The window cannot be operated for
a few seconds after the anti-entrap-
ment function operates.. If the vehicle ’s battery is discon-
nected due to situations such as
battery or fuse replacement, the anti-
entrapment functi on is deactivated.

WARNING
. To prevent dangerous exhaust
gas from entering the vehicle,
always keep the trunk lid closed
while driving.
. Help prevent children, adults or
animals from locking themselves
in the trunk. On hot or sunny
days, the temperature in the
trunk could quickly become high
enough to cause death or serious
heat-related injuries including
brain damage to anyone locked
inside, particularly for small chil-dren.
. When leaving the vehicle, either
close all windows and lock all
doors. Also make certain that the
trunk is closed. &

NOTE
If the connection between the combina-
tion meter and battery is broken for any
reason such as vehicle maintenance or
fuse replacement, the data recorded on
the trip meter will be lost. &Tachometer
The tachometer shows the engine speed
in thousands of revolutions per minute.
CAUTION
Do not operate the engine with the
pointer of the tachometer in the red
zone. This may cause severe da-
mage to the engine. &
Fuel gauge
1) Low fuel warning light
The fuel gauge shows the approximate
amount of fuel remaining in the tank.
When the ignition switch is in the “LOCK ”
or “Acc ”position, the fuel gauge shows “E ”
even if the fuel tank contains fuel.
The gauge may move slightly during
braking, turning or acceleration due to fuel
level movement in the tank.
If you press the trip knob while the ignition
switch is in the “LOCK ”or “Acc ”position,
the fuel gauge will light up and indicate the
amount of fuel remaining in the tank.
If, while the fuel gauge is indicating the
amount of fuel remaining in the tank, you
(a) do not press the trip knob for 10
seconds or (b) open and close the driver ’s door, the fuel gauge indication will turn off.
NOTE
You will see the “”sign in the fuel
gauge meter.
This indicates that the fuel filler door
(lid) is located on the right side of thevehicle. Instruments and controls

steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
If the light illuminates steadily after
blinking for approximately one min-
ute, promptly contact a SUBARU
dealer to have the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low
pressure threshold, the low tire
pressure warning light should turn off a few minutes later. Therefore, be
sure to install the specified size for
the front and rear tires.
& ABS warning light
CAUTION
. If any of the following conditions
occur, we recommend that you
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer. – The warning light does not
illuminate when the ignition
switch is turned to the “ON ”
position.
– The warning light illuminates
when the ignition switch is
turned to the “ON ”position,
but it does not turn off even
when the vehicle speed ex-
ceeds approximately 8 mph
(12 km/h).
– The warning light illuminates
during driving.
. When the warning light is on (and
the brake system warning light is
off), the ABS function shuts
down. However, the conventional
brake system continues to oper- ate normally.
With a vehicle equipped with an EBD
system, the ABS warning light illuminates
together with the brake system warning
light if the EBD system malfunctions. For
further details of the EBD system mal-
function warning, refer to “Electronic
Brake Force Distribution (EBD) systemwarning ”F 3-19.
NOTE
If the warning light behavior is as
described in the following conditions,
the ABS system may be considerednormal. . The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.. The warning light remains illumi-
nated after the engine has been started,
but it turns off when the vehicle speed
reaches approximately 8 mph (12km/h).. The warning light illuminates during
driving, but it turns off immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction.

3-28Instruments and controls
& Average fuel consumption
1) U.S.-spec. models
2) Except U.S.-spec. models
This indication shows the average rate of
fuel consumption since the trip meter was
last reset.
When either of the trip meter indications is
reset, the corresponding average fuel
consumption value is also reset. NOTE . The indicated values vary in accor-
dance with changes in the vehicle ’s
running conditions. Also, the indicated
values may differ slightly from the
actual values and should thus be
treated only as a guide.. When either trip meter indication is
reset, the average fuel consumption corresponding to that trip meter indica-
tion is not shown until the vehicle has
subsequently covered a distance of 1
mile (or 1 km).
& Turn off display of fuel con-
sumption indicator
The display of the fuel consumption
indicator can be turned off.
To turn off the display of the indicator, turn
the ignition switch to the “LOCK ”position
and press the “+ ” button adjacent to the
information display for approximately 5
seconds. Then, the information display
and the clock display will blink for 3
seconds to notify that the display of the
fuel consumption has been turned off.
To restore the indicator, once again pressthe “+ ” button for approximately 5 sec-
onds.
NOTE . The initial display setting of the fuel
consumption indicator of your vehicle
has been set to operational at the time
of shipment from the factory. . The average fuel consumption is
calculated even while the indicator is
not displayed.. Even if you turn off the fuel con-
sumption indicator, the fuel consump-
tion indicator will automatically turn on when the battery voltage is discon-
nected and then reconnected for bat-
tery replacement or fuse replacement.

an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
The two 3-volt lithium batteries (modelCR-1220 ) supplied in your remote engine
start transmitter should last approximately
3 years, depending on usage. When the
batteries begin to weaken, you will notice
a decrease in range (distance from the
vehicle that your remote engine start
system operates). Follow the instructions
below to change the remote engine start
transmitter batteries.
1. Carefully pry the remote engine start
transmitter halves apart using a small flat-
head screwdriver.2. Remove the circuit board from the
bottom half of the case and slide the white
plastic battery holder out from under the
battery tab releasing the batteries. Re-
move the old batteries and replace with
new ones. Be sure to observe the (+) sign
on the old batteries before removing them
to ensure that the new batteries are
inserted properly (battery “+ ” should be
pointed away from the transmitter circuit
board on both batteries).
3. Carefully snap the case halves back
together, then test the remote engine startsystem.
