TRAJECTORY CONTROL SYSTEMS

Anti-slip regulation (ASR) and electronic stability programme(ESP)


The anti-slip regulation (also known as
Traction Control) optimises traction to
prevent skidding of the wheels, by act-
ing on the brakes of the driving wheels
and on the engine.
The electronic stability programme acts
on the brake of one or more wheels and
on the engine to keep the vehicle on the
trajectory required by the driver, within
the limits of the laws of physics.

Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem.
This is indicated by fl ashing of
this warning lamp in the instru-
ment panel.

(Intelligent Traction Control)

Your vehicle has a system to help driving
on snow: Intelligent Traction Control.
This automatic system continuously
checks for situations of diffi cult surface
adhesion that could make it diffi cult to
move off or make progress on deep
fresh snow or compacted snow.
In these situations, Intelligent Traction
Control
takes over from the ASR
sys-
tem, limiting the amount of wheel slip to
provide the best traction and trajectory
control, even without snow tyres and
with or without chains.
In extremely severe conditions (snow
on top of ice, sand, deep mud…), it can
be useful to deactivate the ESP/ASR

systems to allow a degree of wheel spin
and so recover grip.

Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), it may be ad-
visable to deactivate the ASR and ESP
systems, so that the wheels can move
freely and regain grip.


)
Press the "ESP OFF"
button, located
on the left below the steering wheel.

If this warning lamp comes on
in the instrument panel and
the indicator lamp in the button
comes on, this indicates that
the ASR and ESP systems are
deactivated.

ELECTRIC PARKING BRAKE

The electric parking brake combines
2 operating modes:


- Automatic Application/Release


Application is automatic when the
engine stops, release is automatic
on use of the accelerator (activated
by default),

- Manual Application/Release


The parking brake can be applied/
released manually by pulling control
lever A
.
If this warning lamp comes on
in the instrument panel, the au-
tomatic mode is deactivated.
Programming the mode

Depending on the country of sale of the ve-
hicle, the automatic application when the
engine is switched off and the automatic
release when you press the accelerator
can be deactivated.

It is recommended that you do
not apply the parking brake in
very cold conditions (ice) and
during towing (breakdown, cara-
van...). Deactivate the automatic
functions and release the parking
brake manually.

Manual application

With the vehicle stationary, to apply the
parking brake whether the engine is
running or off, pull
control lever A
.
The application of the parking brake is
confi rmed by:


- lighting 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, check
that parking brake warning lamp
in the instrument panel is on
fi xed, not fl ashing.
When the driver’s door is opened with
the engine running, a loud beep is heard
and a message is displayed if the park-
ing brake has not been applied, unless
the gear lever is in position P
(Park) in
the case of an automatic gearbox.
Activation/deactivation is per-
formed using the vehicle confi gu-
ration menu, refer to the section
on parameter settings for the
systems of your vehicle.

The parking brake is then applied and
released manually. When the driver's
door is opened, there is an audible signal
and a message is displayed if the brake
is not applied.

Do not place any object (packet
of cigarettes, telephone...) be-
tween the gear lever and the
electric parking brake control
lever.

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:


- extinction of the braking warn-
ing lamp and of the P
warning
lamp in the control lever A
,

- 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 utilise maximum
application
of the parking brake. It is
obtained by means of a long pull
on
the control lever A
, until you see the
message "Handbrake on maximum"
and a beep is heard.

Maximum application is essential:



- in the case of a vehicle towing a
caravan or a trailer, if the auto-
matic functions are activated but
you are applying the parking brake
manually,

- 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, check
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 parking
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.

Emergency braking

If a failure of the ESP system is
signalled by the illumination 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" 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 programme
(ESP) provides stability during emer-
gency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will
be displayed.
The emergency braking must
only be used in exceptional
circumstances.
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.
