switch is turned to the "ON" position. After
that, this warning light changes to green
and remains illuminated in green for 1
second, and then turns off. It indicates that
the Vehicle Dynamics Control system is
operating normally.
! Vehicle Dynamics Control warning
light (yellow)
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.
If the electrical circuit of the Vehicle
Dynamics Control system itself malfunc-
tions, the warning light only illuminates. At
this time, the ABS (Anti-lock Brake Sys-
tem) remains fully operational.
The warning light illuminates when the
electronic control system of the ABS/
Vehicle Dynamics Control system mal-
functions.
The Vehicle Dynamics Control system
provides its ABS control through the
electrical circuit of the ABS system.
Accordingly, if the ABS is inoperative, the
Vehicle Dynamics Control system be-
comes unable to provide ABS control. As
a result, the Vehicle Dynamics Control
system also becomes inoperative, caus-
ing the warning light to illuminate. 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.
NOTE
If the warning light behavior is as
described below, the Vehicle Dynamics
Control system may be considered
normal.
The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
The warning light illuminates after
engine startup and turns off while the
vehicle is subsequently being driven.
The warning light illuminates during
driving, but it turns off immediately and
remains off.
Instruments and controls
! Vehicle Dynamics Control OFF in-
dicator light (yellow)
This light illuminates when the Vehicle
Dynamics Control OFF switch is pressed
(except WRX STI).
This light illuminates when the Vehicle
Dynamics Control mode switch is pressed
for more than 2 seconds (WRX STI).
The light illuminates when the Vehicle
Dynamics Control system is deactivated.
NOTE
The light may remain illuminated for
a while after the engine has been
started, especially in cold weather. This
does not indicate the existence of a
problem. The light should turn off as
soon as the engine has warmed up.
The indicator light illuminates when
the engine has developed a problem
and the CHECK ENGINE warning light/
malfunction indicator lamp is on.
The Vehicle Dynamics Control system is
probably malfunctioning under the follow-
ing condition. Have your vehicle checked
at a SUBARU dealer as soon as possible.
The light does not turn off even after
the lapse of several minutes (the engine
has warmed up) after the engine has
started.
