The light does not come on when the ignition switch
is turned to the “ON” position. " The light does not go out even after a period of
about 2 seconds after the ignition switch has been
turned to the “ON” position. ! Vehicle Dynamics Control warn-
ing light (if equipped)/Vehicle Dy-
namics Control OFF indicator
light (if equipped)
This warning light has the function of indicating faults
in the Vehicle Dynamics Control system and the func-
tion of indicating that the Vehicle Dynamics Control
system has been deactivated.
It comes on in the event of a fault in the system and is
on when the system is not operating.
This warning light comes on when the ignition switch
is turned to the “ON” position and goes out after the
engine has started. It indicates that the Vehicle Dy-
namics Control system is in normal operation. ! Vehicle Dynamics Control warning light
The Vehicle Dynamics Control system is probably in-
operative under any of the following conditions. Have
your vehicle checked at a SUBARU dealer immediate- ly."
The warning light does not come on when the igni-
tion switch is turned to the “ON” position. " The warning light comes on while the vehicle is run-
ning. " If the electrical circuit of the Vehicle Dynamics Con-
trol system itself becomes faulty, the warning light only
comes on. At this time, the ABS (Anti-lock Brake Sys-
tem) remains fully operational. " The warning light comes on when the electronic
control system of the ABS/Vehicle Dynamics Control
system becomes faulty.
The Vehicle Dynamics Control system provides its
ABS control through the electrical circuit of the ABS
system. Accordingly, if the ABS is inoperative, the Ve-
hicle Dynamics Control system becomes unable to
provide ABS control. As a result, the Vehicle Dynam-
ics Control system also becomes inoperative, causing
the warning light to come on. Though both the Vehicle
Dynamics Control and ABS systems 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 have your vehicle checked at a
SUBARU dealer as soon as possible.

should occur, have an authorized SUBARU dealer
carry out an inspection of that system at the first avail-
able opportunity. "
The indicator light does not turn on when the ignition
key is turned to the ON position. " The indicator light does not turn off approximately
two seconds after the ignition key has been turned to
the ON position. ! Vehicle Dynamics Control warning light/Vehi-
cle Dynamics Control OFF indicator light
This single light has the function of indicating malfunc-
tions in the Vehicle Dynamics Control system and the
function of indicating that the Vehicle Dynamics Con- trol system is not operating. It comes on in the event
of a malfunction in the system and is illuminated when-
ever the system is not operating. "
Vehicle Dynamics Control warning
The warning light comes on when the ignition switch is
turned to the “ON” position and goes off several sec-
onds after engine startup. This lighting pattern indi-
cates that the Vehicle Dynamics Control system is op-
erating normally.
The following situations could indicate a malfunction of
the Vehicle Dynamics Control system; if any should
occur, we recommend that you have an authorized
SUBARU dealer carry out an inspection of the system
at the first available opportunity. " The warning light does not turn on when the ignition
key is turned to the ON position. " The warning light turns on while the vehicle is being
driven. " When a malfunction has occurred in the Vehicle Dy-
namics Control electrical system, only the warninglight will turn on. In such an event, the ABS will still be
operating normally. " The warning light will also turn on when a problem
occurs with the ABS or Vehicle Dynamics Control
electronic control systems.
Because the Vehicle Dynamics Control system con-

trols each brake through the ABS, whenever the ABS
stops operating due to a malfunction in that electrical
system, the Vehicle Dynamics Control will also be-
come unable to control all four brakes. Thus Vehicle
Dynamics Control system operation halts and the
warning light turns on. Although both the Vehicle Dy-
namics Control system and the ABS will be inoperable
in this situation, it will still be possible to stop the vehi-
cle using normal braking. The Vehicle Dynamics Con-
trol system and the ABS do not adversely affect oper-
ation of the vehicle in any way when they are inopera-
ble; however should such a situation occur, drive with
care and have an authorized SUBARU dealer carry
out an inspection of those systems at the first available
opportunity.
NOTE
When the warning light turns on and off in the fol-
lowing way, it indicates that the Vehicle Dynamics
Control system is operating normally. "Although turning on after the engine has been
started, the warning light quickly turns off and
stays off. " The warning light turns on when the vehicle is
being driven; it then turns off and stays off. " Vehicle Dynamics Control OFF indicator light
This light comes on to indicate that the Vehicle Dy- namics Control system is in non-operation mode. This
does not constitute failure of the Vehicle DynamicsControl system.
NOTE "
The indicator light may stay on for a while after
the engine has been started, especially in cold
weather. This occurs because the engine has not
yet warmed up and is completely normal. The light
will turn off when the engine has reached a suit-
able operating temperature. " When an engine problem occurs and the mal-
function indicator lamp turns on, the indicator
light will also come on.
The following two situations could indicate malfunction
of the Vehicle Dynamics Control system; if either
should occur, have an authorized SUBARU dealer
carry out an inspection of that system at the first avail-
able opportunity. " The indicator light does not turn on when the ignition
key is turned to the ON position. " The indicator light fails to turn off after the engine is
started, even when several minutes have passed to al-
low the engine to heat up sufficiently.

Washing
"When washing the vehicle, the brakes may
get wet. As a result, the brake stopping dis-
tance will be longer. To dry the brakes, drive the
vehicle at a safe speed while lightly pressing
the brake pedal to heat up the brakes." Do not wash the engine compartment and ar-
eas adjacent to it. If water enters the engine air
intake, electrical parts or the power steering flu-
id reservoir, it will cause engine trouble or
faulty power steering respectively.
The best way to preserve your vehicle’s beauty is fre-
quent washing. Wash the vehicle at least once a
month to avoid contamination by road grime.
Wash dirt off with a wet sponge and plenty of luke-
warm or cold water. Do not wash the vehicle with hot
water and in direct sunlight.
Salt, chemicals, insects, tar, soot and bird droppings
should be washed off by using a light detergent, as re- quired. If you use a light detergent, make certain that
it is a neutral detergent. Do not use strong soap or
chemical detergents. All cleaning agents should be
promptly flushed from the surface and not allowed to
dry there. Rinse the vehicle thoroughly with plenty of
lukewarm water. Wipe the remaining water off with a
chamois or soft cloth.
NOTE
When having your vehicle washed in an automatic
car wash, make sure beforehand that the car wash
is of suitable type. Automatic car wash brushes or
other equipment may damage the rear wiper and
rear/roof spoiler (if equipped). !
Washing the underbody
Chemicals, salts and gravel used for deicing road sur-
faces are extremely corrosive, accelerating the corro-
sion of underbody components, such as the exhaust
system, fuel and brake lines, brake cables, floor pan
and fenders, and suspension.
Thoroughly flush the underbody and inside of the
fenders with lukewarm or cold water at frequent inter-
vals to reduce the harmful effects of such agents.
Mud and sand adhering to the underbody components may accelerate their corrosion.
After driving off-road or muddy or sandy roads, wash
