■Fuel GaugeThe fuel gauge shows the approximate
amount of fuel remaining in the tank.
When the ignition switch is in the “OFF” or
“ACC” position, the fuel gauge shows “E”
even if the fuel tank contains fuel.
The gauge may move slightly due to fuel
level movement in the tank (e.g., during
braking, turning or acceleration).NOTEYou will see the “ ” sign in the fuel
gauge. This indicates that the fuel filler
lid is located on the right side of the
vehicle.
■ Engine Coolant Temperature
GaugeThe temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON” position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
■ Outside TemperatureDisplays the outside temperature within
the range of -40°F (-40°C) to 122°F
(50°C). Low outside temperature indicator
comes on when the ambient temperature
is 37°F (3°C) or lower.NOTEThe outside temperature indicator
shows the temperature around the
sensor. However, the temperature may
not be indicated correctly or the
update may be delayed in the follow-
ing conditions.
 While parking or driving at low
speeds
 When the outside temperature
changes suddenly (example: when
going in and out of an underground
parking area or when passing through
a tunnel)
 When starting the engine after being
parked for a certain period of time

If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Oth-
erwise an accident involving
serious vehicle damage and serious
personal injury could occur.1) Keep driving straight ahead while
gradually reducing speed.2) Slowly pull off the road to a safe
place.If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you
have a flat tire, replace it with a
spare tire as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the Low tire pres-
sure warning light will illuminate
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 possi-
ble for tire and sensor replacement
and/or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
CAUTION
The tire pressure monitoring sys-
tem is NOT a substitute for manu-
ally checking tire pressure. The tire
pressure should be checked period-
ically (at least monthly) using a tire
gauge. After any change to tire
pressure(s), the tire pressure moni-
toring system will not re-check tire
inflation pressures until the vehicle
is first driven mo re than 25 mph (40
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 25 mph (40 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low pres-
sure threshold, the low tire pres-
sure warning light should turn off a
few minutes later. Therefore, be
sure to install the specified size for
the front and rear tires.

Warning and Indicator Lights
141
Instruments and Controls3
– CONTINUED –
If the brake system warning light should
illuminate while driving (with the parking
brake fully released and with the ignition
switch positioned in “ON”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN” mark in the reser-
voir, do not drive the vehicle. Have the
vehicle towed to the nearest SUBARU
dealer for repair.▼ Electronic Brake Force Distribution
(EBD) system warning
If the warning light remains on even
though the parking brake is released, the
brake fluid level may be low or there could
be a problem with the EBD system. Park
the vehicle in a safe place immediately
and contact a SUBARU dealer.
▼ Vacuum pressure system warning
The brake system warning light will illumi-
nate when the vacuum pressure sensor is
malfunctioning or brake booster pressure
is decreasing. If the light continues to illu-
minate for several minutes after starting
the engine, there may be a malfunction in
the vacuum system. In this case, drive the
vehicle carefully and have the system
inspected by a SUBARU dealer.
■ Low Fuel Warning LightThe low fuel warning light illuminates
when the tank is nearly empty approxi-
mately 1.8 US gal (7.0 liters, or 1.5 Imp
gal). It only operates when the ignition
switch is in the “ON” position.■ Door Open IndicatorWhen any of the doors or the trunk lid is
not fully closed, the door open indicator
appears. This function is effective even if
the ignition switch is in the “OFF” or “ACC”
position.
The open door is indicated by the corre-
sponding part of the door open indicator.
Always make sure this indicator does not
appear before you start to drive.■ Power Steering
Warning LightWhile the engine is running, a warning
light illuminates and a buzzer sounds if a malfunction is detected in the electric

power steering system.
NOTEIf the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent
the system components, such as the
control computer and drive motor,
from overheating.
 The steering wheel is operated
frequently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently
turning the steering wheel during
parallel parking.
 The steering wheel remains in the
fully turned position for a long period
of time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light illu-
minates. Engine misfires as a result
of an empty tank could cause dam-
age to the engine.
CAUTION
When the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.
