Safety Precautions When Driving
7
Introduction
– CONTINUED –
For instructions and precautions, carefully
read the following sections.
 For the seatbelt system, refer to "Seat-
belts"  P39.
 For the child restraint system, refer to
"Child Restraint Systems" P46.
 For the SRS airbag system, refer to
"SRS Airbag (Supplemental Restraint
System Airbag)" P60.
■ Engine Exhaust Gas (Carbon
Monoxide)
■Drinking and Driving
Put children aged 12 and under or
1.5 m (4 feet 11 inches) tall or less
in the REAR seat properly
restrained at all times in a child
restraint system or in a seatbelt.
The SRS airbag deploys with
considerable speed and force
and can injure or even kill chil-
dren, especially if they are 12
years of age and under or 1.5 m (4
feet 11 inches) tall or less and are
not restrained or improperly
restrained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater.
WARNING
 Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is
dangerous, or even lethal, if
inhaled. Always properly maintain the
engine exhaust system to prevent
engine exhaust gas from entering
the vehicle. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it. Avoid remaining in a parked
vehicle for a long time while the
engine is running. If that is
unavoidable, then use the ventila-
tion fan to force fresh air into the
vehicle. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system
always works properly.
 If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open. Keep the trunk lid closed while
driving to prevent exhaust gas
from entering the vehicle.
WARNING
Drinking and then driving is very
dangerous. Alcohol in the blood-
stream delays your reaction and
impairs your perception, judgment
and attentiveness. If you drive after
drinking even if you drink just a lit-
tle it will increase the risk of being
involved in a serious or fatal acci-
dent, injuring or killing yourself,
your passengers and others. In
addition, if you are injured in the
accident, alcohol may increase the
severity of that injury.Please don’t drink and drive.

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
cap will not make the CHECK ENGINE
warning light/malfunction indicator light
turn off immediately. It may take several
driving trips. If the light does not turn off,
take your vehicle to your authorized
SUBARU dealer immediately.
▼ If the light is blinking
If the light is blinking while driving, an
engine misfire condition has been
detected which may damage the emission
control system.
To prevent serious damage to the emis-
sion control system, you should conform
to the following instructions.
 Reduce vehicle speed.
 Avoid hard acceleration.
 Avoid steep uphill grades.
 Reduce the amount of cargo, if
possible. The CHECK ENGINE warning light/
malfunction indicator light may stop

blinking and illuminate steadily after
several driving trips. You should have
your vehicle checked by an authorized
SUBARU dealer immediately.

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"
 P319- Blinking in RED and BLUE
alternately: 
The electrical system may be
malfunctioning. Contact your
SUBARU dealer for an inspec-
tion.
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.

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.

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.
