Control warning light (if
equipped)/Vehicle Dynamics Control OFF indicator light (if
equipped)/Traction Control OFF indicator light
(WRX STI)

This warning light has both the function of
indicating malfunctions in the Vehicle
Dynamics Control system and the function
of indicating that the Vehicle Dynamics
Control system has been deactivated or
only the Traction Control system has been
deactivated.
It illuminates in the event of a malfunction
in the system and is on when the Vehicle
Dynamics Control system is not operating
or only the Traction Control system is not
operating.
Except WRX STI
This warning light illuminates when the
ignition switch is turned to the “ON”
position and turns off several seconds
after engine startup. It indicates that the
Vehicle Dynamics Control system is operating normally.
WRX STI
This 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.

following conditions. Have your vehicle
checked at a SUBARU dealer immediately.
. 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 malfunctions, the warning light only illuminates. At
this time, the ABS (Anti-lock Brake System) remains fully operational.
. The warning light illuminates when the
electronic control system of the ABS/
Vehicle Dynamics Control system malfunctions.

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 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.
