Particular situations


In cer tain situations (e.g. star ting the engine),
the parking brake can automatically alter its
force. This is normal operation.
To advance your vehicle a few centimetres
without star ting 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 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
. In the event of a failure of the main ser vice
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 the electric parking brake
malfunctioning or the battery running flat, an
emergency manual device can release the
parking brake.

Operation

The system inter venes only when driving
economically.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.

- The system may suggest that you engage a
higher gear, if appropriate.
The information appears in the instrument
panel in the form of an arrow accompanied by
the suggested gear.

In the case of driving which makes
particular demands on the performance
of the engine (firm pressure on the
accelerator pedal, for example, when
over taking...), the system will not
recommend a gear change.
The system never suggests:


- engaging first gear,

- engaging reverse gear,

- engaging a lower gear.
