Your vehicle is equipped with a seatbelt
warning device at the driver ’s and front
passenger ’s seat, as required by current
safety standards.
With the ignition switch turned to the “ON ”
position, this device reminds the driver
and front passenger to fasten their seat-
belts by illuminating the warning lights in
the locations indicated in the following
illustration and sounding a chime.
Driver ’s warning light (turbo models)
Driver ’s warning light (non-turbo models)
Front passenger ’s warning light
! Operation
If the driver and/or front passenger have/
has not yet fastened the seatbelt(s) when
the ignition switch is turned to the “ON ”
position, the seatbelt warning light(s) will
flash for 6 seconds, to warn that the
seatbelt(s) is/are unfastened. If the dri-ver ’s seatbelt is not fastened, a chime will
also sound simultaneously. NOTE . If the driver ’s and/or front passen-
ger ’s seatbelt(s) are/is still not fastened
6 seconds later, the seatbelt warning
device operates as follows according
to the vehicle speed.
–At speeds lower than approxi-
mately 9 mph (15 km/h)

The warning light(s) for unfastened
seatbelt(s) will alternate between
steady illumination and flashing at
15-second intervals. The chime will
not sound. –At speeds higher than approxi-
mately 9 mph (15 km/h)
The warning light(s) for unfastened
seatbelt(s) will alternate between
flashing and steady illumination at
15-second intervals and the chime
will sound while the warning light(s)
is/are flashing.
. It is possible to cancel the warning
operation that follows the 6-second
warning after turning ON the ignition
switch. When the ignition switch is
turned ON next time, however, the
complete sequence of the warning
operation resumes. For further details
about canceling the warning operation,
please contact your SUBARU dealer.
If there is no passenger on the front passenger ’s seat, the seatbelt warning
device for the front passenger ’s seat will
be deactivated. The front passenger ’s
occupant detection system monitors
whether or not there is a passenger on
the front passenger ’s seat.
Observe the following precautions. Failure
to do so may prevent the device from
functioning correctly or cause the device to fail. .
Do not install any accessory such as a
table or TV onto the seatback.. Do not store a heavy load in the
seatback pocket.. Do not allow the rear seat occupant to
place his/her hands or legs on the front passenger ’s seatback, or allow him/her to
pull the seatback. . Do not use front seats with their back-
ward-forward position and seatback not
being locked into place securely. If any of
them are not locked securely, adjust them
again. For adjusting procedure, refer to“ Front seats ”F 1-2.
If the seatbelt warning device for the front passenger ’s seat does not function cor-
rectly (e.g., it is activated even when the
front passenger ’s seat is empty or it is
deactivated even when the front passen-
ger has not fastened his/her seatbelt),
take the following actions. . Ensure that no article is placed on the
seat other than a child restraint system
and its child occupant, although we
strongly recommend that all children sit
in the rear seat properly restrained. . Ensure that there is no article left in the
seatback pocket.. Ensure that the backward-forward po-
sition and seatback of front passenger ’s seat are locked into place securely by
moving the seat back and forth.
If still the seatbelt warning device for front passenger
’s seat does not function cor-
rectly after taking relevant corrective ac-
tions described above, immediately con-
tact your SUBARU dealer for an inspec-tion.
& SRS airbag system
warning light
WARNING
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system. Immediately take your vehi-
cle to your nearest SUBARU dealer
to have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS

tion switch is turned to the “ON ”position.
After that, this indicator light/warning light
changes to BLUEand maintains illumina-
tion in BLUE. This BLUE illuminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature in-
creases over the specified range, the
indicator light/warning light blinks inRED . At this time, the engine is close to
overheating.
If the engine coolant temperature in-
creases further, the indicator light/warning
light illuminates in REDcontinuously. At
this time, the engine may be overheating.
When the indicator light/warning light
blinks in REDor illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps to take in the
case of engine overheating. Refer to“ Engine overheating ”F 9-13. 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. NOTE
If 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 light
If 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 alternator 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
immediately. &Oil pressure warning light
If 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
engine at the first safe opportunity and check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil is
at the proper level but the light remains
illuminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to“
Engine oil ”F 11-10.

7-8Starting and operating
CAUTION
Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program or its
contractors or licensees.
The EPA has issued regulations for
inspecting the On-Board Diagnostic
(OBD) system as part of the state emis-
sions inspection. The OBD system is
designed to detect engine and transmis-
sion problems that might cause vehicle
emissions to exceed allowable limits.
These inspections apply to all 1996 model
year and newer passenger cars and light
trucks. Over 30 states plus the District of
Columbia have implemented the OBD
system inspection. . The inspection of the OBD system
consists of a visual operational check of the “CHECK ENGINE ”warning light/mal-
function indicator lamp (MIL) and an
examination of the OBD system with an
electronic scan tool while the engine isrunning. . Avehicle
passes the OBD system
inspection if proper illumination of the “ CHECK ENGINE ”warning light/MIL is
observed, there are nostored diagnostic trouble codes, and the OBD system
readiness monitors are complete. .
A vehicle
fails the OBD inspection if the
“ CHECK ENGINE ”warning light/MIL is
not properly operating or there are one or
more diagnostic trouble codes stored in
the vehicle ’s computer with the “CHECK
ENGINE ”warning light/MIL illuminated.
. A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBD system readiness monitors “Not
Ready ”is greater than one. Under this
condition, the vehicle operator should be
instructed to drive his/her vehicle for a few
days to set the monitors and return for an
emission re-inspection. . Owners of rejected or failing vehicles
should contact their SUBARU Dealer for service. Preparing to drive
You should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition
of the tires. Also check tires for properinflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood, trunk (4-door)
and rear gate (5-door) are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside
and outside mirrors.
7. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
8. Check the operation of the warning
and indicator lights when the ignition
switch is turned to the
“ON ”position.
9. Check the gauges, indicator and warn-
ing lights after starting the engine.
NOTE
Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.

8-6Driving tips
Off road driving
WARNING
. Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-tions.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive model could easily
lead to a serious accident.
CAUTION
Do not drive on rough roads or over
curbs in a vehicle that has 17-inch
or other ultra-low-profile tires. The
wheels and tires could be damaged
by shock forces, leading to abnor-
mal vibration or poor straight-line
tracking. Driving would then be
more difficult. &
All AWD models except OUTBACK
Your AWD model is neither a conventional
off-road vehicle nor an all terrain vehicle. It
is a passenger vehicle designed primarily
for on-road use. The AWD feature gives it
some limited off-road capabilities in situa-
tions in which driving surfaces are rela-
tively level, obstruction-free and otherwise
similar to on-road driving conditions. Op-
erating it under other than those condi-
tions could subject the vehicle to exces-
sive stress which might result in damage
not eligible for repair under warranty. If you
do take your SUBARU off-road, you
should review the common sense precau-
tions in the next section (applicable to the
OUTBACK) for general guidance. But
please keep in mind that your vehicle ’s
off-road capabilities are more limited than
those of the OUTBACK.
Never attempt to drive through pools and
puddles, or roads flooded with water.
Water entering the engine air intake or
the exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall. &
OUTBACK
Your SUBARU can be driven on ordinary
roads or off-road. But please keep in mind
that an AWD SUBARU is a passenger
vehicle and is neither a conventional off-
road vehicle nor an all-terrain vehicle. If
you do take your SUBARU off-road,
certain common sense precautions such
as those in the following list should betaken. . Make certain that you and all of your
passengers are wearing seatbelts.. Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio. . Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain. . Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like. . Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep. . Avoid sharp turning maneuvers, espe-

that are of the same size, con-
struction, brand, and load range.
Mixing other sizes or construc-
tions may result in severe me-
chanical damage to the drive
train of your vehicle and may
affect ride, handling, braking and
speedometer/odometer calibra-
tion. It also may be dangerous
and lead to loss of vehicle con-trol.
. Do not use a combination of
radial, belted bias or bias tires
since it may cause dangerous
handling characteristics and lead
to an accident.
! Turbo models
Your vehicle is equipped with “summer
tires ”as original equipment, which are
inadequate for driving on slippery roads
such as on snow-covered or icy roads.
Compared with winter and all-season
tires, summer tires give significantly less
grip on snowy and icy road surfaces.
Therefore, use of winter tires is strongly
recommended when driving with such
road conditions.
When you choose to install winter tires on
your vehicle, be sure to use the correct tire
size and type. You must install four winter tires that are of the same size, construc-
tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body.
Remember to drive with care at all times
regardless of the type of tires on yourvehicle. !
Non-turbo models
Your vehicle is equipped with “all season
tires ”as original equipment, which are
designed to provide an adequate measure
of traction, handling and braking perfor-
mance in year-round driving. In winter, it
may be possible to enhance performance
through use of tires designed specifically
for winter driving conditions.
When you choose to install winter tires on
your vehicle, be sure to use the correct tire
size and type. You must install four winter
tires that are of the same size, construc-
tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body. Remember to drive with care at all times
regardless of the type of tires on yourvehicle.
& Tire chains
CAUTION
Tire chains cannot be used on your
Impreza, WRX and STI because of
the lack of clearance between the
tires and vehicle body.
& Rocking the vehicle
If you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever/select lever back and forth between“ 1 ”/“ D ”and “R ”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
If your vehicle is an AT model, for
information about holding the transmission
in the 2nd position, refer to “Selection of
manual mode ”F 7-26. Driving tips
