Emergency braking
In the event of a failure of the main service
brake or in an exceptional situation (e.g. driver
t
aken ill, under instruction, etc.) a continuous
p
ull on the control lever will brake the vehicle.
B
raking takes place while the control lever is
b
eing pulled. It is interrupted if the control lever
i
s
r
eleased.
The ABS and DSC systems provide stability of
the
vehicle during emergency braking.
If
the emergency braking malfunctions, the
m
essage "Parking brake control faulty" will be
d
isplayed.
If a failure of the ABS and DSC systems occurs,
signalled
by the illumination of one or both
w
arning lamps in the instrument panel, then
s
tability of the vehicle is no longer guaranteed.
In this event, stability must be assured by the
driver
by repeating alternate "pull-release"
a
ctions on the control lever until the vehicle is
immobilised. The
emergency braking should only be
u
sed in an exceptional situation.
Repeat this procedure to reactivate automatic
operation.
Reactivation of automatic operation is
confirmed by the indicator lamp in the
instrument
panel
going
off.
Deactivating automatic operation
In some situations, such as very cold weather
or towing (caravan, recovery), it may be
n
ecessary to deactivate automatic operation of
the
system.
