TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid 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. Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.


Press the "ESP OFF" button, located
in the centre of the dashboard.
If this warning lamp comes
on in the instrument panel
and the indicator lamp on the
button comes on, this indi-
cates that the ASR and ESP
systems are deactivated.
This is indicated by fl ashing
of this warning lamp on the
instrument panel.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. Intelligent Traction Control
system *
Your vehicle has a system to help
driving on snow.
This automatic system continuously
checks for situations of diffi cult sur-
face adhesion that could make it dif-
fi cult to move off or make progress
on deep fresh snow or compacted
snow.
In these situations, the system takes
over from the
ASR system by opti-
mising the amount of wheel slip to
provide the best traction and trajec-
tory 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.
* Depending on engine type.

Reactivation
These systems are reactivated au-
tomatically each time the ignition is
switched back on or from 30 mph
(50 km/h).


Press the "ESP OFF" button again to reactivate them manually.
Operating fault If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer. The ESP/ASR systems offer ex-
ceptional safety in normal driving,
but this should not encourage the
driver to take extra risks or drive at
high speed.
The correct functioning of these
systems depends on observation
of the manufacturer's recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.

* According to country.
Side airbags *
System which protects the driver
and front passenger in the event of
a serious side impact in order to limit
the risk of injury to the chest.
Each side airbag is incorporated in
the front seat back frame, on the
door side.
Operation
It is triggered unilaterally in the
event of a serious side impact ap-
plied to all or part of the side impact
zone
B , perpendicular to the longi-
tudinal centreline of the vehicle on
a horizontal plane and directed from
the outside towards the inside of the
vehicle.
The side airbag infl ates between the
front occupant of the vehicle and the
corresponding door trim pad. Impact detection zones

A. Front impact zone.

B. Side impact zone.
Curtain airbags *
System which protects the driver and passengers (with the exception of the rear centre passenger) in the event of a serious side impact in or-der to limit the risk of head injuries.
Each curtain airbag is incorporated in the pillars and the upper part of the passenger compartment.
Operation
It is triggered at the same time as the corresponding side airbag in the event of a serious side impact applied to all or part of the side impact zone B , per-pendicular to the longitudinal centreli-ne of the vehicle on a horizontal plane and directed from the outside towards the inside of the vehicle.
The curtain airbag infl ates between the front or rear occupant of the ve-hicle and the windows.
In the event of a minor impact or
bump on the side of the vehicle or
if the vehicle rolls over, the airbag
may not be triggered.
The airbag is not triggered in the
event of a rear or front collision.
Operating fault
If this warning lamp comes on in the instrument panel, accompanied by an audible signal and a message on the multifunction screen, contact a CITROËN dealer to have the sys-the multifunction screen, contact a
tem checked. The airbags may no longer be triggered in the event of a serious impact.

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.

D R I V I N G The parking assistance system
cannot, in any circumstances, re-
place the need for vigilance and
responsibility on the part of the
driver.
AUDIBLE AND VISUAL FRONT AND REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located in front
of and behind the vehicle, except for
obstacles located immediately be-
low the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking assistance is
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicated
by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the vehicle
and the obstacle is less than approxi-
mately thirty centimetres, the audible
signal becomes continuous and/or the
"Danger" symbol appears, depending
on the multifunction screen version. The parking assistance is
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward gear,
- when the vehicle has been station- ary for more than three seconds in
forward gear.
