Manual release
With the ignition on or the engine run-
ning, to release the parking brake,
press
on the brake
pedal
or the accel-
erator, pull then release
control A
.
The full application of the parking brake
is confi rmed by:
- the braking warning lamp
and the P
warning lamp in
the control lever A
going off,
- display of the message
"Handbrake off".
If you pull control lever A
with-
out pressing the brake pedal,
the parking brake will not be
released and a warning lamp
will come on in the instrument
panel.
Maximum application
If necessary, you can make a maxi-
mum application
of the parking brake.
This is obtained by means of a long
pull
on the control lever A
, until you
see the message "Handbrake on maxi-
mum" and a beep is heard.
Maximum application is essential:
- in the case of a vehicle towing a
caravan or a trailer, if the automatic
functions are activated but you are
applying the parking brake manu-
ally,
- when the gradient you are parked
on may vary (e.g. on a ferry, on a
lorry, during towing),
In the case of towing, a loaded vehicle
or parking on a gradient, make a maxi-
mum application of the parking brake
then turn the front wheels towards the
pavement and engage a gear when you
park.
After a maximum application, the re-
lease time will be longer.
Automatic application,
engine off
With the vehicle stationary, the parking
brake is automatically applied when
the engine is switched off
.
The application of the parking brake is
confi rmed by:
-
illumination of the braking warn-
ing lamp and of the P
warning
lamp in the control lever A
,
- display of the message
"Handbrake on".
Before leaving the vehicle, en-
sure that parking brake warning
lamp in the instrument panel is
on fi xed (not fl ashing).
Never leave a child alone inside
the vehicle with the ignition on,
as they could release the park-
ing brake.
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.

going off and display of the message
"Handbrake off".
If the parking brake develops a fault
while applied
or if the battery runs fl at,
an emergency release is always pos-
sible.
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
.

Emergency braking
In the event of failure of the elec-
tronic stability control system,
signalled by the illumination of
this warning lamp, braking sta-
bility 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
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.
The emergency braking must
only be used in exceptional cir-
cumstances.
Emergency release
In the event of the electric parking brake
malfunctioning or the battery running
fl at, an emergency manual device can
release the parking brake.

GEAR EFFICIENCY INDICATOR *
System which reduces fuel consump-
tion by advising the driver to change up
on vehicles fi tted with a manual gearbox.
*
According to engine.
Operation
The system intervenes only when driv-
ing 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 recommenda-
tions must not be considered compulso-
ry. In fact, the confi guration of the road,
the amount of traffi c 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.
- You press the accelerator pedal
moderately.
Example:
- You are in third gear.
- The system may suggest that you
engage a higher gear, if appropriate.
The information appears in the instru-
ment 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
(fi rm pressure on the accelerator
pedal, for example, when over-
taking...), the system will not rec-
ommend a gear change.
The system never suggests:
- engaging fi rst gear,
- engaging reverse gear,
- engaging a lower gear.

The gears engaged appear in
succession in the instrument
panel screen.
The gear change requests are only act-
ed on if the engine speed permits.
It is not necessary to release the accel-
erator during gear changes.
When braking or slowing down, the
gearbox changes down automatically
to allow the vehicle to accelerate in the
correct gear.
On sharp acceleration, the gearbox will
not change up unless the driver acts on
the gear lever or the steering mounted
paddles.
Temporary control of gear changing
You can temporarily take over control
of gear changing using the "+"
and "-"
steering mounted paddles: if the engine
speed allows, the request to change
gear is acted on.
This function allows you to anticipate
certain situations such as overtaking a
vehicle or the approach to a corner.
After a few moments without any action
on the control paddles, the gearbox re-
sumes automatic control of the gears.
Never select neutral N
while the
vehicle is moving.
In both cases, you must apply the
