Safety Precautions When Driving■ Seatbelt and SRS Airbag
For instructions and precautions, carefully
read the following sections.
 For the seatbelt syst em, refer to "Seat-
belts" P39.
 For the SRS airbag system, refer to
"SRS Airbag (Supplemental Restraint
System Airbag)" P60.

Prevent explosions
WARNING
 All persons in the vehicle must
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-
dent. To obtain maximum protection in
the event of an accident, the
driver and all passengers must
always wear seatbelts when in
the vehicle. The SRS (Supple-
mental Restraint System) airbag
does not do away with the need to
fasten seatbelts. In combination
with the seatbelts, it offers the
best combined protection in case
of a serious accident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag.
 The SRS airbags deploy with
considerable speed and force.
Occupants who are out of the
proper position when the SRS
airbag deploys could suffer very
serious injuries. Because the
SRS airbag needs enough space
for deployment, the driver should
always sit upright and well back
in the seat as far from the steering
wheel as practical while still
maintaining full vehicle control
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.

WARNING
All persons in the vehicle should
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-
dent. All belts should fit snugly in order
to provide full restraint. Loose
fitting belts are not as effective in
preventing or reducing injury. Each seatbelt is designed to
support only one person. Never
use a single belt for two or more
persons – even children. Other-
wise, in an accident, serious
injury or death could result.
 Replace all seatbelt assemblies
including retractors and
attaching hardware worn by
occupants of a vehicle that has
been in a serious accident. Also,
be sure to replace seatbelt
assemblies that show signs of
severe fraying or having been
cut. The entire assembly should
be replaced even if damage is not
obvious. Seat children in the rear seat
properly restrained at all times.
The SRS airbag deploys with
considerable speed and force
and can injure or even kill chil-
dren, especially if they are not
restrained or improperly
restrained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater. For that
reason, we strongly recommend
that ALL children (including
those in child restraint systems)
sit in the REAR seat properly
restrained at all times in a child
restraint system or in a seatbelt,
whichever is appropriate for the
child’s height and weight. Secure
ALL types of child restraint
systems in the REAR seats at all
times.

■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

Warning and Indicator Lights
136■CHECK ENGINE 
Warning Light/
Malfunction Indicator LightIf this light illuminates steadily or blinks
while the engine is running, it may indicate
that there is at least one problem or poten-
tial problem somewhere in the emission
control system.
▼ If the light illuminates constantly
If the light illuminates constantly while
driving or does not turn off after the engine
starts, an emission control system
malfunction has been detected.
We recommend that you have your
vehicle checked by an authorized
SUBARU dealer immediately.
NOTEThis light also illuminates when the
fuel filler cap is not tightened until it
clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator light coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure not hing is interfering
with the sealing of the cap. Tightening the

Warning and Indicator Lights
137
Instruments and Controls3
– CONTINUED –
This coolant temperature low indicator
light/coolant temper ature high warning
light has the following three functions.
 Illumination in BLUE indicates insuffi-
cient warming up of the engine
 Blinking in RED indicates that the
engine is close to overheating
 Illumination in RED indicates over-
heating condition of the engine
For the system check, this indicator light/
warning light illuminates in RED for
approximately 2 seconds when the igni-
tion switch is turned to the “ON” position.
After that, this indicator light/warning light
changes to BLUE and maintains illumina- tion in
BLUE. This BLUE illuminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature
increases over the specified range, the
indicator light/warning light blinks in RED.
At this time, the engine is close to over-
heating.
If the engine coolant temperature
increases further, the indicator light/
warning light illuminates in RED continu-
ously. At this time, the engine may be
overheating.
When the indicator light/warning light
blinks in RED or illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps for the
engine overheating. Refer to "Engine
Overheating" P319. After that, have the
system checked by your nearest
SUBARU dealer.
Also, if the indicator light/warning light
often blinks in RED, the electrical system
may be malfunctioning. Contact your
SUBARU dealer for an inspection.
NOTEIf the engine is restarted after a certain
driving condition, this indicator light/
warning light may illuminate in RED.
However, this is not a malfunction if the indicator light/warning light turns

off after a short time.
■ Charge Warning LightIf this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the drive belt. If the belt is loose,
broken or if the belt is in good condition
but the light remains illuminated, contact
your nearest SUBARU dealer immedi-
ately.■ Oil Pressure Warning
LightIf this light illuminates when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
- Blinking or illuminated in
RED: 
Safely stop the vehicle as
soon as possible, and refer to
the emergency steps for the
engine overheating. After that,
have the system checked by
your nearest SUBARU dealer.
Refer to "Engine Overheating"

Warning and Indicator Lights
138engine at the first safe opportunity and
contact your nearest SUBARU dealer
immediately.■ AT OIL TEMP Warning
Light (AT Models) If this light illuminates when the engine is
running, it may indicate that the transmis-
sion fluid temperature is too hot.
If the light illuminates while driving, imme-
diately stop the vehicle in a safe place and
let the engine idle until the warning light
turns off.■ Low Tire Pressure
Warning Light (If
Equipped)When the ignition switch is turned to the
“ON” position, the low tire pressure
warning light will illuminate for approxi-
mately 2 seconds to check that the tire
pressure monitoring system (TPMS) is
functioning properly. If there is no problem
and all tires are properly inflated, the light
will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the

proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi-
nates a low tire pressure telltale when one
or more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TP MS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain
correct tire pressure, even if under-infla-
tion has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is no t operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for approximately one minute and then remain continuously

illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate
steadily after blinking for approximately
one minute, have the system inspected by
your nearest SUBARU dealer as soon as
possible.
WARNING
If this light does not illuminate
briefly after the ig nition switch is
turned on or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
