Starting and operating

The warning light illuminates in yellow for
approximately 1 second when the ignition
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.
The following situations could indicate a
malfunction of the Vehicle Dynamics
Control system; if any should occur, have
an authorized SUBARU dealer carry out
an inspection of the system at the first
available opportunity.
. The warning light does not illuminate
when the ignition switch is turned to the
ON position.
. The warning light illuminates while the
vehicle is being driven.
. When a malfunction has occurred in
the Vehicle Dynamics Control electrical
system, only the warning light will illuminate. In such an event, the ABS will still be
operating normally.
. The warning light will also illuminate
when a problem occurs with the ABS or
Vehicle Dynamics Control electronic control systems.
Because the Vehicle Dynamics Control

system controls each brake through the
ABS, whenever the ABS stops operating
due to a malfunction in that electrical
system, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halts and the warning
light illuminates. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using
normal braking. The Vehicle Dynamics
Control system and the ABS do not
adversely affect operation of the vehicle
in any way when they are inoperable;
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 illuminates and
turns off in the following way, it indicates that the Vehicle Dynamics
Control system is operating normally.
. Although illuminating after the engine has been started, the warning light
quickly turns off and remains off.
. The warning light illuminates when
the vehicle is being driven and then it
then turns off and remains off.

! Vehicle Dynamics Control OFF indicator light (yellow)
This light illuminates to indicate that the
Vehicle Dynamics Control system is in
non-operation mode. This does not constitute failure of the Vehicle Dynamics
Control system.

NOTE
. The indicator light may remain illuminated 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 suitable operating temperature.
. When an engine problem occurs
and the CHECK ENGINE warning light/
malfunction indicator lamp illuminates,
the indicator light will also illuminate.
The following situations could indicate a
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
available opportunity.
. The indicator light does not illuminate
when the ignition switch is turned to the
“ON” position.
. The indicator light fails to turn off after
the engine is started, even when several
