Deactivation
In exceptional conditions (starting a vehicle which is bogged down,
stuck in snow, on soft ground...), it may be advisable to deactivate the
DSC and ASR, so that the wheels can turn freely and regain grip.
Reactivate the systems as soon as the level of grip permits.
 Press this button.
The indicator lamp in the button comes on.
The DSC and ASR systems no longer act on the operation of the engine
and on the brakes in the event of a involuntary change of trajectory.
This action also deactivates the automatic operation of hazard warning
lamps (except for the 1.6 litre THP 270 hp version).
Reactivation
The systems are reactivated automatically each time the ignition is
switched back on.
You can also reactivate them manually:
 Press this button again.
This action also reactivates the automatic operation of hazard warning
lamps (except for the 1.6 litre THP 270 hp version).
Operating fault
Illumination of this warning lamp and the lamp in the
deactivation button, accompanied by an audible signal and a
message, indicate a fault with the system.
Contact a PEUGEOT dealer or a qualifi ed workshop to have the system
checked.
DSC/ASR
The DSC and ASR systems offer increased safety in normal
driving, but they should not encourage the driver to take extra
risks or drive at high speed.
It is in diffi cult driving conditions (rain, snow, ice) that the risk of
loss of grip increases. It is therefore important for your safety to
keep the DSC and ASR systems activated in all conditions, and
particularly in diffi cult conditions.
The correct operation of these systems depends on observation
of the manufacturer's recommendations regarding as much the
wheels (tyres and rims), braking and electronic components as the
assembly and repair procedures used by PEUGEOT dealers.
To benefi t in full from the effectiveness of the DSC and ASR
systems in wintry conditions, the vehicle must be fi tted with four
snow tyres, allowing the the vehicle to retain neutral behaviour on
the road.
After an impact, have these systems checked by a PEUGEOT
dealer or a qualifi ed workshop.
