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 AB S contr ol 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.

! 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.
