served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
.A vehicle fails the OBDII inspection if
the“CHECK ENGINE”warning light is not
properly operating (light is illuminated or is
not working due to faulty LED [Light
Emitting Diode]) or there is one or more
diagnostic trouble codes stored in the
vehicle’s computer.
.A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors“NOT
READY”is greater than one. If the
vehicle’s battery has been recently re-
placed or disconnected, the OBDII system
inspection may indicate that the vehicle is
not ready for the emission test. Under this
condition, the vehicle driver should be
instructed to drive his/her vehicle for a
few days to reset the readiness monitors
and return for an emission re-inspection.
.Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Some states still use dynamometers in
their emission inspection program. A
dynamometer is a treadmill or roller-like
testing device that allows your vehicle’s
wheels to turn while the vehicle remains in
one place. Prior to your vehicle being puton a dynamometer, tell your emission
inspector not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer.Otherwise, serious transmis-
sion damage will result.
The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
program have EXEMPTED SUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer. There are some states that
use four-wheel dynamometers in their
testing program. When properly used, this
equipment should not damage a SUBARU
AWD vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected in
an attempt to bypass AWD for state
emission testing. An AWD vehicles must
be tested using an AWD dynamometer
with all 4 wheels driven and loaded.
Preparing to driveYou 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 proper
inflation.
3. Look under the vehicle for any sign of
leaks, and check that no small animal is
under the vehicle.
4. Check that no small animal enters the
engine compartment.
5. Check that the hood and trunk lid are
fully closed.
6. Check the adjustment of the seat.
7. Check the adjustment of the inside and
outside mirrors.
8. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
9. Check the operation of the warning
and indicator lights when the ignition
switch is turned to the“ON”position.
10. Check the gauges, indicator and warn-
ing lights after starting the engine.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Starting and stopping the en-
gine&General precautions when
starting/stopping engine
WARNING
.Never start the engine from out-
side the vehicle. It may result in
an accident.
.Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can cre-
ate a fire hazard at high tempera-
tures.
.Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
CAUTION
.Do not stop the engine while
driving. Otherwise, the catalyst
may overheat and burn.
.When starting the engine, be sureto sit in the driver’s seat (except
when using the remote engine
start system).
NOTE.Avoid rapid acceleration immedi-
ately after the engine has started. In
addition, always avoid rapid racing.
.Until the engine is warmed up suffi-
ciently, the engine speed is maintained
high. The engine speed will gradually
drop as the engine warms up.
.On rare occasions, it may be difficult
to start the engine depending on the
fuel used and the driving condition
(repeated short trips when the engine
is not warmed up sufficiently). In such
cases, it is recommended to switch to a
different brand of fuel.
.On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly such
as a rapid start-up and a rapid accel-
eration. This is not a malfunction.
.The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
.It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically

Electronic Brake Force Dis-
tribution (EBD) systemThe EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of the
braking force. It functions by adjusting the
distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
system malfunction, the EBD system also
stops working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
&Steps to take if EBD system
malfunctionsBrake and ABS warning lightIf a malfunction occurs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light illuminate simultaneously.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
while driving.
Even if the EBD system malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps.
1. Stop the vehicle in the nearest safe, flat
location.
2. Apply the parking brake and turn off the
engine.
3. Restart the engine.
4. Release the parking brake.
Even if both warning lights turn off:
The EBD system may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again.
2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to“Checking the fluid level”F11-24.
.If the brake fluid level is not below the
“MIN”mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
.If the brake fluid level is below the“MIN”
mark, DO NOT drive the vehicle. Instead,
have the vehicle towed to the nearest

more than approximately 2 seconds during
engine operation, the mode of the Vehicle
Dynamics Control system will be changed.
!Vehicle Dynamics Control mode
When the ignition switch is on, this mode is
selected first.
This mode enables all controls for ABS,
the Traction Control System, and the
Vehicle Dynamics Control system. Select
this mode for most driving situations.
When this mode is selected, both indicator
lights on the combination meter turn off.!Traction mode
This mode restricts the functions of the
Traction Control System and Vehicle Dy-
namics Control system and thus delays
utilizing their functions as a reaction to
vehicle behavior in comparison with the
Vehicle Dynamics Control mode. Use this
mode in driving situations where the
vehicle dynamic performance will improve
without decreasing engine torque control.
When you press the switch briefly during
engine operation, the traction mode in-
dicator light and the Vehicle Dynamics
Control OFF indicator light on the combi-
nation meter illuminate. When you press
the switch again to reactivate the Vehicle
Dynamics Control system, the traction
mode indicator light and the Vehicle

trol”F3-71.
!BSD/RCTA approach warning buz-
zer (only when reversing)
A warning buzzer sounds along with
flashing of the BSD/RCTA approach in-
dicator light to warn the driver of dangers.
You can change the setting of the warning
buzzer volume by operating the combina-
tion meter display (color LCD). For details,
refer to“BSD/RCTA”F3-43.
!Safety tips regarding the BSD/RCTA
