Servicing
WARNING
If the warning light exhibits any of
the following conditions, immedi-
ately stop the vehicle in a safe
place, and consult a SUBARU
dealer. Unless a technician checks
and repairs the system as needed,
the seatbelt pretensioners and/or
the SRS airbag will not operate
properly in the event of a collision,
which may result in injury. Flashing or flickering of the
warning light No illumination of the warning
light when the ignition switch is
first turned to the “ON” position Continuous illumination of the
warning light Illumination of the warning light
while driving
WARNING
 When discarding an airbag
module or scrapping the entire
vehicle damaged by a collision,
consult your SUBARU dealer. The SRS airbag has no user-
serviceable parts. Do not use
electrical test equipment on any
circuit related to the SRS airbag
system. For required servicing of
the SRS airbag, consult your
nearest SUBARU dealer.
Tampering with or disconnecting
the system’s wiring could result
in accidental inflation of the SRS
airbag or could make the system
inoperative, which may result in
serious injury.
CAUTION
If you need service or repair in
areas indicated in the following list,
have the work performed by an
authorized SUBARU dealer. The
SRS airbag control module, impact
sensors and airbag modules are
stored in these areas.

- Installation of additional elec- trical/electronic equipment
such as a mobile two-way
radio on or near the SRS
airbag system components
and/or wiring is not advisable.
This could interfere with
proper operation of the SRS
airbag system.- Modifications on or inside the
door panels for the purpose of
a speaker replacement or
sound insulation
 The impact sensors, which detect
the pressure of an impact, are
located in the doors. Do not
modify any components of the
doors or door trims, such as the
addition of door speakers for
example. Any modifications to
the doors will create a risk of the
airbag system becoming inopera-
tive or unintended airbag deploy-
ment.
CAUTION
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the SRS airbag system.
 Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than
genuine SUBARU accessory
parts to the front end. Modification of the suspension
system or front end structure. Installation of a tire of different
size and construction from the
tires specified on the vehicle
placard attached to the driver’s
center pillar or specified for indi-
vidual vehicle models in this
Owner’s Manual. Attachment of any equipment
(side steps or side sill protectors,

2) Operating range (approximately 16 to
32 in (40 to 80 cm))
1) LED indicator
When the access key fob is within either of
the operating ranges of the doors, the
LED indicator on the access key fob
flashes. When the keyless access func-
tions are disabled, the LED indicator does
not flash unless a button on the access
key fob is pressed.NOTE If the access key fob is placed too
close to the vehicle body, the keyless
access functions may not operate
properly. If it does not operate prop-
erly, repeat the operation from farther
away.
 If the access key fob is placed near
the ground or in an elevated location
from the ground, even if it is in the indi-
cated operating range, the keyless
access function may not operate prop-
erly.
 When the access key fob is within
the operating range, it is possible for
anyone, even someone who is not
carrying the access key fob, to operate
the keyless access function. Note that
the keyless access function can be
operated only by the door handle, door
lock sensor or trunk opener button in
the operating range in which the
access key fob is detected.
 It is not possible to lock the doors,
trunk lid and fuel filler lid using the keyless access function when the

access key fob is inside the vehicle.
However, depending on the status of
the access key fob and the environ-
mental conditions, the access key fob
may be locked inside the vehicle.
Before locking the vehicle, make sure
that you have the access key fob.
 When the battery of the access key
fob is discharged, or when operating it
in a location with strong radio waves or
noise (e.g., near a radio tower, power
plant, broadcast station or an area
where wireless equipment is used), or
while talking on a cell phone, the oper-
ating ranges may be reduced, or the
keyless access function may not
operate. 
In such a case, perform the procedure
described in "Locking and Unlocking"
 P326.
 The doors may lock or unlock when
the car is being washed or exposed to
a significant amount of water that
touches the door handle while the key
fob is still in the operating range.

Meters and Gauges

Instruments and Controls3
– CONTINUED –
■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

CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.Refer to "Engine Overheating"

Warning and Indicator Lights
139
Instruments and Controls3
– CONTINUED –
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.
