Instruments and controls
y The VDC warning light does not come on when the
ignition switch is turned to the “ON” position.
y
The VDC warning light remains on after the engine
has started and stays lit even when the vehicle speed
reaches about 8 mph (12 km/h).
y
The VDC warning light comes on while the vehicle
is running.
y
If the electrical circuit of the VDC system itself be-
comes faulty, the VDC warning light only comes on. At
this time, the ABS (Anti-lock Brake System) remains
fully operational.
y
The warning light comes on when the electronic
control system of the ABS/VDC system becomes
faulty.
The VDC system provides its ABS control through the
electrical circuit of the ABS system. Accordingly, if the
ABS is inoperative, the VDC system also becomes un-
able to provide ABS control. As a result, the VDC sys-
tem becomes inoperative, causing the VDC warning
light to come on. Though both the VDC and ABS sys-
tems are inoperative in this case, the ordinary func-
tions of the brake system are still available. You will be
safe while driving with this condition, but you should
have your vehicle checked at a SUBARU dealer as
soon as possible.
NOTE
If the warning light behavior is as described be-
low, the VDC system may be considered normal.
y
The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off.
y
The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches 8 mph about (12 km/h).
y
The warning light comes on during driving, but
it goes out immediately and remains off.
„ Brake system warning light
y Driving with the brake system warning light
on is dangerous. This indicates your brake sys-
tem may not be working properly. If the light re-
mains on, have the brakes inspected by a
SUBARU dealer immediately.
y
If at all in doubt about whether the brakes are
operating properly, do not drive the vehicle.
Have your vehicle towed to the nearest
SUBARU dealer for repair.
