Emergency or
assistance call
This system allows you to make an emergency
or assistance call to the emergency ser vices or
to the dedicated CITROËN ser vice.
Audible warning system to alert other roadusers to an imminent danger.
) Press the central part of the mutlifunction steering wheel.
Use the horn moderately and only in the following circumstances: - immediate danger,- approaching a location lacking visibility.
For more information on the use of this function, refer to the "Audio andtelematics" section.

Ty r e u n d e r - i nfl ation detection System which automatically checks the pressure of the tyres while driving.
Sensors fitted in each valve trigger a warning in
the event of malfunction (speed above 12 mph(20 km/h)).
The spare wheel is not fitted with a sensor.

All repairs and changing of tyres on a wheel fitted with this system must becarried out by a CITROËN dealer or a
qualified workshop.
If, when changing a tyre, you install a wheel which is not detected by your vehicle (example: fitting of snow tyres),you must have the system reinitialised by a CITROËN dealer or a qualifiedworkshop.
This message is also displayed whenone of the wheels is away from thevehicle (being repaired) or when one or more wheels without a sensor are fitted.


The tyre under-inflation detectionsystem is an aid to driving which doesnot replace the need for the driver to bevigilant or to drive responsibly.

This system does not avoid the needto have the tyre pressures checkedregularly (refer to "Identification markings") to ensure that the optimumdynamic per formance of the vehicle is maintained and prevent premature wear of the tyres, particularly in arduousdriving conditions (heavy load, highspeed). The tyre pressures must be checked cold, at least once a month. Remember to check the pressure of the spare wheel.

The tyre under-inflation detectionsystem may experience temporary inter ference due to electromagnetic signals on a frequency close to thatused by the system.
A message appears in the instrument panel screen, accompanied by an audible signal, to
identify the wheel concerned.
Under-infl ated tyre
This warning lamp andthe STOPwarning lamp come on, accompanied by an audible signal and a message in the
instrument panel screen identifying the wheelconcerned. )Stop immediately, avoiding any sudden
movement of the steering wheel and the brakes. ) Change the damaged wheel (punctured or
very deflated tyre), and have the tyre pressurechecked as soon as possible.


Puncture

A message appears in the instrument panel
screen, accompanied by an audible signal,
to identi
fy the wheel or wheels which are not
detected or to indicate a fault in the system.
Contact a CITROËN dealer or a qualified
workshop to replace the faulty sensor(s).

Safety
Electronic Stability Programme
(ESC: Electronic Stability Control) incorporating
the following systems:


- the anti-lock braking system (ABS) and
the electronic brake force distribution(EBFD),

- the emergency braking assistance,

- the anti-slip regulation (ASR) or tractioncontrol,

- the dynamic stability control (DSC).









Electronic stability programme (ESC)
Definitions
Anti-lock braking system (ABS)and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and offers improved control in corners, in par ticular on poor or slippery road surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to reach the optimum braking pressure more quickly and therefore reduce the stopping distance. It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by a reduction in the resistance of the pedal and an increase in the effectiveness of the braking.

Anti-skid regulation (ASR)

The ASR system (also known as Traction Control) optimises traction in order to avoid
wheel slip b
y acting on the brakes of the drivingwheels and on the engine. It also improves
the directional stability of the vehicle onacceleration.


Dynamic stability control (DSC)

If there is a difference between the path followed by the vehicle and that required bythe driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws of physics.

Snow driving assistance
(Intelligent Traction Control)
Your vehicle has a system to help driving onsnow: Intelligent Traction Control.This automatic system continuously checks
for situations of difficult surface adhesion thatcould make it difficult to move off or makeprogress on deep fresh snow or compactedsnow.
In these situations, Intelligent Traction
Contro
llimits the amount of wheel slip toprovide the best traction and trajectory control.
In extremely severe conditions (deep snow,mud…), it can be useful to temporarily deactivate the dynamicstabilitycontroland
wheel anti-slip systems to allow a degree of
wheel spin and so recover grip.It is recommended that the system be reactivated as soon as possible. Snow tyres are strongly recommended on sur faces offering low levels of adhesion.


Operation


Anti-lock braking system (ABS)
and electronic brake force
distribution
(EBFD)
In emergency braking, press very firmly without releasing the pressure.

When changing wheels (tyres and rims),make sure that these are approved for your vehicle.
Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal. When this warnin
g lamp comes on,
accompanied by an audible signal
and a message, it indicates that
there is a fault with the ABS, which
could cause loss of control of the vehicle whenbraking.
When this warnin
g lamp comes on, coupled with the STOPwarning lamp,
accompanied by an audible signal
and a message, it indicates that
th
ere is a fault with the electronic brake forcedistribution (EBFD), which could cause loss of control of the vehicle when braking.
You must stop as soon as it is safe to do so. In both cases, contact a CITROËN dealer or a qualified workshop.

Safety
Dynamic stability control(DSC)

Activation
This system is activated automatically eachtime the vehicle is started.
It comes into operation in the event of a grip or
tra
jectory problem.
This is indicated by
flashing of thiswarning lamp in the instrument panel.

Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate
the DSC system, so that the wheels can move freely and regain grip.

The DSC system offers exceptional
safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed.
The correct operation of the system depends on obser vation of the manufacturer's recommendationsregarding the wheels (tyres and rims),the braking components, the electronic components and the CITROËN assembly and operation procedures.
After an impact, have the systemchecked by a CITROËN dealer or a qualified workshop.

Operating fault


If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, this indicates a fault
with the s
ystem.
Contact a CITROËN dealer or a qualifiedworkshop to have the system checked.
Reactivation
The system is reactivated automatically each
time the ignition is switched back on or from 30 mph (50 km/h).
) Press the button.
This warnin
g lamp and the indicator
lamp in the button come on: the
DSC s
ystem no longer acts on theoperation of the engine.
)
Press the button again to
reactivate it manually. But it is recommended that the s
ystem be
reactivated as soon as possible.

173Safety
Airbags

System designed to maximise the safety of the
occupants
(with the exception of the rear centrepassenger) in the event of violent collisions.
It supplements the action of the force-limitingseat belts (with the exception of the rear centrepassenger).
I
f a collision occurs, the electronic detectors
record and analyse the front and side impacts sustained in the impact detection zones:


- in the case of a serious impact, the airbags are deployed instantly and protect
the occupants of the vehicle (with theexception of the rear centre passenger);
immediately after the impact, the airbags
deflate rapidly so that they do not hinder
visibility or the exit of the occupants,

- in the case of a minor or rear impact or incertain roll-over conditions, the airbags
will not be deployed; the seat belt alone is
sufficient to provide optimum protection in
these situations.
The airbags do not operate when the ignition is switched off.

This equipment will only deploy once. If a second impact occurs (during thesame or a subsequent accident), the airbag will not be deployed again.
Deployment of the airbag(s) is accompanied by a slight emission of harmless smoke and a noise, due to the activation of the pyrotechniccar tridge incorporated in the system. This smoke is not harmful, but sensitiveindividuals may experience slight irritation.
The noise of the detonation may resultin a slight loss of hearing for a shor ttime.

Front airbags


Deployment

The airbags are deployed simultaneously, unless
the passenger's front airbag is deactivated, in
the event of a serious front impact to all or par t
of the front impact zone A, in the longitudinalcentreline of the vehicle on a horizontal plane anddirected from the front to the rear of the vehicle.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the steering wheel, driver's side, and the dashboard,
passen
ger's side to cushion their for ward
movement. S
ystem which protects the driver and front
passenger in the event of a serious front impact
in order to limit the risk of injury to the head and
thorax.
The driver's airbag is fitted in the centre of the steering wheel; the front passenger's airbag isfitted in the dashboard above the glove box.

Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between theoccupants and the airbags (a child, pet,
object...). This could hamper the operation of the airbags or injure the occupants. After an accident or if the vehicle has beenstolen or broken into, have the airbagsystems checked. All work on the airbag system must be carried out by a CITROËN dealer or a qualified workshop.
Even if all of the precautions mentioned are obser ved, a risk of injury or of minor burns to the head, chest or arms when an airbag is deployed cannot be ruled out. Thebag inflates almost instantly (within a few milliseconds) then deflates within the sametime discharging the hot gas via openings provided for this purpose.
Lateral airbags
Use only approved covers on the seats, compatible with the deployment the lateral airbags. For information on the range of seatcovers suitable for your vehicle, you can contact a CITROËN dealer (see "Practical information - § Accessories"). Do not fix or attach anything to the seat backs (clothing...). This could cause injuryto the chest or arms if the lateral airbag isdeployed.Do not sit with the upper par t of the body anynearer to the door than necessary.

Front airbags

Do not drive holding the steering wheel by its spokes or resting your hands on the centre part of the wheel.
Passengers must not place their feet on thedashboard.
If possible, do not smoke as deployment of the airbags can cause burns or the risk of injury from a cigarette or pipe.
Never remove or pierce the steering wheel or hit it violently.
Curtain airbags
Do not fix or attach anything to the roof. This could cause injury to the head if the cur tain airbag is deployed. If fitted on your vehicle, do not remove thegrab handles installed on the roof, they play a par t in securing the cur tain airbags.

For the airbags to be fully effective, observe the following safety rules:
