Dynamics Control op-
eration indicator light!Vehicle Dynamics Control warning
light
CAUTION
The Vehicle Dynamics Control sys-
tem provides its ABS control
through the electrical circuit of the
ABS. Accordingly, if the ABS is
inoperative, the Vehicle Dynamics
Control system becomes unable to
provide ABS control. As a result, the
Vehicle Dynamics Control system
also becomes inoperative, causing
the warning light to illuminate.
Though both the Vehicle Dynamics
Control and ABS are inoperative in
this case, the ordinary functions of
the brake system are still available.
You will be safe while driving with
this condition, but drive carefully
and have your vehicle checked at a
SUBARU dealer as soon as possi-
ble.
NOTE.If the electrical circuit of the Vehicle
Dynamics Control system itself mal-
functions, the warning light only illumi-
nates. At this time, the ABS (Anti-lock
Brake System) remains fully opera-
tional.
.The warning light illuminates when
the electronic control system of the
ABS/Vehicle Dynamics Control system
malfunctions.
The Vehicle Dynamics Control system is
probably inoperative under any of the
following conditions. Have your vehicle
checked at a SUBARU dealer immedi-
ately.
.The warning light does not illuminate
when the ignition switch is turned to the
“ON”position.
.The warning light illuminates while the
vehicle is running.
NOTEIf the warning light behavior is as
described in the following examples,
the Vehicle Dynamics Control system
may be considered normal.
.The warning light illuminates when
the ignition switch is turned to the“ON”
position and turns off approximately 2
seconds after the engine has started.
.The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
.The warning light illuminates after
the engine has started and turns off
while the vehicle is subsequently being
driven.
.The warning light illuminates while
driving, but it turns off immediately and
remains off.
.The warning light illuminates when
the engine has stalled and continues to
illuminate after the engine has been
restarted. However, it will turn off once
the vehicle starts moving.

DefrostingPerform either of the following operations
to defrost or to dehumidify the windshield
and front door windows.
.Select the“
”mode by pressing the
defroster button (both types A and B)
.Select the“”mode by turning the
airflow mode selection dial (type A)
.Select the“”mode by pressing the
airflow mode selection button (type B)
NOTEWhen the“
”or“
”mode is se-
lected, the air conditioner compressor
operates automatically regardless of
the position of the air conditioner
button to defrost the windshield more
quickly. However the indicator on the
air conditioner button will not illumi-
nate. At the same time, the air inlet
selection is automatically set to the
outside air mode. After defrosting the
windshield by pressing the defroster
button“
”, pressing the button again
returns the system to the setting that
had been selected before the defroster
was activated.
Operating tips for heater and
air conditioner&Cleaning ventilation grille1) Front ventilation inlet grilleAlways keep the front ventilation inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept clean
because cooling performance is impaired
by any accumulation of insects and leaves
on the condenser.
&Efficient cooling after parking
in direct sunlightAfter parking in direct sunlight, drive with
the windows open for a few minutes to
allow outside air to circulate into the
heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of the
air conditioner for maximum cooling effi-
ciency.&Lubrication oil circulation in
the refrigerant circuitOperate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil.&Checking air conditioning
system before summer sea-
sonCheck the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer.

and may produce a sulfur exhaust odor or
smell. SUBARU recommends that you try
a different brand of unleaded gasoline
having lower sulfur to determine if the
problem is fuel related before returning
your vehicle to an authorized dealer for
service.
!MMT
Some gasoline contains an octane-enhan-
cing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/Mal-
function indicator light may turn on. If this
happens, return to your authorized
SUBARU Dealer for service. If it is
determined that the condition is caused
by the type of fuel used, repairs may not be
covered by your warranty.
!Gasoline for cleaner air
Your use of gasoline with detergent ad-
ditives will help prevent deposits from
forming in your engine and fuel system.
This helps keep your engine in tune and
your emission control system working
properly, and is a way of doing your part
for cleaner air. If you continuously use a
high quality fuel with the proper detergent
and other additives, you should never
need to add any fuel system cleaningagents to your fuel tank.
Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as ethanol
(ethyl or grain alcohol) may be used in your
vehicle, but should contain no more than
10% ethanol for the proper operation of
your SUBARU.
Do not use any gasoline that contains
more than 10% ethanol, including from any
pump labeled E15, E30, E50 or E85 (which
are only some examples of fuel containing
more than 10% ethanol).
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station op-
erators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-
sions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
.Fuel should be unleaded and have anoctane rating no lower than that specified
in this manual.
.Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLYif it does not exceed 5% of the fuel
mixtureANDif it is accompanied by
sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanolEXCEPT
under these conditions.
.If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
.Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
CAUTION
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels con-
taining alcohol may cause paint
damage, which is not covered under
the SUBARU Limited Warranty.
