Maximum application is essential:
- in the case of a vehicle towing a caravan or a trailer, if the au-
tomatic functions are activated
but you are applying the parking
brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),
- in the case of towing, a loaded vehicle or parking on a gradient,
turn the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer.
Before leaving the vehicle,
check that warning lamp P
on the instrument panel is
permanently lit.

Dynamic emergency braking
In the event of a failure of the vehi-
cle’s main braking system or in an
exceptional situation (e.g. driver tak-
en ill, under instruction, etc) a con-
tinuous pull on the control lever A will
stop the vehicle.
The electronic stability programme
(ESP) provides stability during dy-
namic emergency braking.
If the dynamic emergency braking
malfunctions, one of the following
messages will be displayed on the
multifunction screen:
- "Parking brake faulty".
- "Parking brake control faulty". If a failure of the ESP sys-
tem is signalled by the light-
ing of this warning lamp,
then braking stability is not
guaranteed. In this event, stability
must be assured by the driver by
repeating alternate "pull release" ac-
tions on control lever A .
The dynamic emergency
braking must only be used in
exceptional circumstances.

System which holds your vehicle tem-
porarily (approximately 2 seconds)
when starting on a gradient, the time it
takes to move your foot from the brake
pedal to the accelerator pedal.

vehicle stationary, the vehicle is
held for a brief moment when you
release the brake pedal:
- provided you are in fi rst gear or neutral on a manual gearbox,
- provided you are in A or M on an
electronic gearbox,
- provided you are in D or M on an
automatic gearbox.
On a descending slope, with the
vehicle stationary and reverse
gear engaged, the vehicle is held
