Immobilising the vehicle,
engine running
With the engine running and the vehicle
stationary, in order to immobilise the vehicle
it is essential to manually apply the parking
brake by pulling control lever A .
The application of the parking brake is
confirmed by:
- illumination of the braking
warning lamp and the P warning
lamp in the control lever A ,
- display of the message
"Handbrake on".
When the driver's door is opened, a message is
displayed accompanied by an audible signal,
if the parking brake has not been applied,
except in the case of an automatic gearbox with
the gear lever in position P .
Before leaving the vehicle, ensure
that parking brake warning lamp in the
instrument panel is on fixed, not flashing.
Particular situations
In certain situations (e.g. starting the engine),
the parking brake can automatically alter its
force. This is normal operation.
To advance your vehicle a few centimetres
without starting the engine, but with the ignition
on, press on the brake pedal and release the
parking brake by pulling then releasing the
control lever A . The full release of the parking
brake is confirmed by the warning lamps
in the control lever A and in the instrument
panel going off and display of the message
"Handbrake off".
If the parking brake develops a fault while
applied or if the battery runs flat, an
emergency release is always possible.
Emergency braking
In the event of a failure of the main service
brake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc) a continuous
pull on the control lever A will stop the vehicle.
The electronic stability control provides stability
during emergency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will be
displayed.
In the event of failure of the electronic
stability control system, signalled by
the illumination of this warning lamp,
braking stability is then not guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release" actions
on the control lever A .
The emergency braking must only be
used in exceptional circumstances.
