Emergency braking


In the event of a failure of the main servicebrake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc
) a continuous
pull on the control lever will brake the vehicle.
Brakin
g takes place while the control lever is
being pulled. It is interrupted if the control lever
is released.
The ABS and DSC systems provide stability of
the vehicle during emergency braking.
If the emergency braking malfunctions, the
message "Parking brake control faulty" will be
displayed.

I
f a failure of the ABS and DSC systems, signalled by the illumination of one or both
warning lamps in the instrument panel, thenstability of the vehicle is no longer guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release" actions on the control lever until the vehicle is immobilised.



The emergency braking should only be used in an exceptional situation.
Re
peat this procedure to reactivate automatic
operation.
Reactivation of automatic operation is
confirmed by the indicator lamp in the instrument panel going off.
