SAFETY
TYRE UNDER-INFLATION DETECTION
Sensors fi tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h)).

Under-infl ated tyre The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver.
Puncture
The service warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction screen lo-
cating the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The STOP
warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction screen lo-
cating the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punc-
tured or very defl ated tyre), and
have the tyre pressure checked as
soon as possible.

Sensor(s) not detected or faulty
The service warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction screen
locating the wheel or wheels which
are not detected or indicating a fault
in the system.
Have the faulty sensor(s) checked
by a CITROËN dealer or a qualifi ed
workshop. All repairs and changing of tyres
on a wheel fi tted with this system
must be carried out by a CITROËN
dealer or a qualifi ed workshop.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: fi tting
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer or a qualifi ed workshop.

This system does not avoid the need to have the tyre pressures checked
regularly (refer to the "Technical
data - Identifi cation markings" sec-
tion) to ensure that the optimum
dynamic performance of the vehicle
is maintained and prevent prema-
ture wear of the tyres, particularly in
arduous driving conditions (heavy
load, high speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detection
system may experience temporary
interference due to electro-magnetic
signals on a frequency close to that
used by the system.
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired) or
when one or more wheels without a
sensor are fi tted.
The spare wheel is not fi tted with a
sensor.

SAFETY
BRAKING ASSISTANCE
SYSTEMS
Group of supplementary systems
which help you to obtain optimum
braking in complete safety in emer-
gency situations:


- anti-lock braking system (ABS),

- electronic brake force distribu-
tion (EBFD),

- emergency braking assistance
(EBA).


Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the
stability and manoeuvrability of your
vehicle when braking, in particular
on poor or slippery surfaces.

Activation
The anti-lock braking system comes
into operation automatically when
there is a risk of wheel lock.
Normal operation of the ABS may
make itself felt by slight vibration of
the brake pedal.
Operating fault

When braking in an emergency,
press very fi rmly without releasing
the pressure. If this warning lamp comes
on, accompanied by an au-
dible signal and a message
in the screen, it indicates a
malfunction of the anti-lock braking
system which could result in loss of
control of the vehicle when braking.
If this warning lamp comes
on, together with the STOP

and ABS
warning lamps,
accompanied by an audible
signal and a message in the screen,
it indicates a malfunction of the elec-
tronic brake force distribution which
could result in loss of control of the
vehicle when braking.

You must stop as soon as it is
safe to do so.

In either case, contact a CITROËN
dealer or a qualifi ed workshop.

When replacing wheels (tyres and
rims), ensure that they conform to
the manufacturer's recommenda-
tions.











Emergency braking assistance

System which, in an emergency,
enables you to obtain the optimum
braking pressure more quickly, thus
reducing the stopping distance.

Activation
It is triggered by the speed at which
the brake pedal is pressed.
The effect of this is a reduction in
the resistance of the pedal and an
increase in braking effi ciency.
When braking in an emergency,
press fi rmly without releasing the
pressure.

SAFETY
TRAJECTORY CONTROL
SYSTEMS

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

The anti-slip regulation (also known
as Traction Control) optimises trac-
tion to prevent skidding of the wheels,
by acting 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.

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, lo-
cated in the centre of the dash-
board.
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 in 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.

SAFETY

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
in the multifunction screen,
this indicates a malfunction of these
systems.
Have it checked by a CITROËN
dealer or a qualifi ed workshop. 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 operation of these sys-
tems depends on observation of
the manufacturer's recommenda-
tions regarding wheels (tyres and
rims), braking components, elec-
tronic components and assembly
and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualifi ed workshop.

EMERGENCY OR
ASSISTANCE CALL
This system allows you to make an
emergency or assistance call to the
emergency services or to the dedi-
cated CITROËN service.
For more information on the use of
this function, refer to the "Audio and
telematics" section.

SAFETY

AIRBAGS



System designed to maximise the
safety of the occupants (with the
exception of the rear centre pas-
senger) in the event of violent col-
lisions. It supplements the action of
the force-limiting seat belts.
If 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 the exception of the
rear centre passenger); imme-
diately after the impact, the air-
bags defl ate rapidly so that they
do not hinder visibility or the exit
of the occupants,

- in the case of a minor or rear im-
pact or in certain roll-over con-
ditions, the airbags will not be
deployed; the seat belt alone
is suffi cient to provide optimum
protection in these situations.

The airbags do not operate
when the ignition is switched
off.
This equipment will only operate
once. If a second impact occurs
(during the same or a subsequent ac-
cident), the airbag will not operate.
Impact detection zones


A.
Front impact zone.

B.
Side impact zone.
Deployment of the airbag(s) is ac-
companied by a slight emission of
harmless smoke and a noise, due to
the activation of the pyrotechnic car-
tridge incorporated in the system.
This smoke is not harmful, but sen-
sitive individuals may experience
slight irritation.
The noise of the detonation may
result in a slight loss of hearing for
a short time.








Front airbags

System which protects the head and
chest of the driver and front passen-
ger in the event of a front impact.
The driver's airbag is fi tted in the
centre of the steering wheel; the
front passenger's airbag is fi tted in
the dashboard above the glove box.

Deployment
The airbags are deployed simultane-
ously, unless the passenger's front
airbag is deactivated, in the event of
a serious front impact applied to all
or part of the front impact zone A
,
in the longitudinal centreline of the
vehicle on a horizontal plane and di-
rected from the front to the rear of
the vehicle.
The front airbag infl ates between the
front occupant of the vehicle and the
dashboard to cushion their forward
movement.

VIII
138
SAFETY













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

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 the dashboard.
If possible, do not smoke as deploy-
ment 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.



Lateral airbags
Use only approved covers on the seats,
compatible with the deployment the
lateral airbags. For information on the
range of seat covers suitable for your
vehicle, you can contact a CITROËN
dealer (see "Practical information - §
Accessories").
Do not fi x or attach anything to the
seat backs (clothing...). This could
cause injury to the chest or arms if
the lateral airbag is deployed.
Do not sit with the upper part of the
body any nearer to the door than
necessary.
Curtain airbags
Do not fi x or attach anything to the
roof. This could cause injury to the
head if the curtain airbag is de-
ployed.
If fi tted on your vehicle, do not re-
move the grab handles installed on
the roof, they play a part in securing
the curtain airbags.
Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the
occupants 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 been stolen or broken into, have
the airbag systems checked.
All work on the airbag system must
be carried out by a CITROËN dealer
or a qualifi ed workshop.
Even if all of the precautions men-
tioned are observed, a risk of injury
or of minor burns to the head, chest
or arms when an airbag is deployed
cannot be ruled out. The bag infl ates
almost instantly (within a few mil-
liseconds) then defl ates within the
same time discharging the hot gas
via openings provided for this pur-
pose.

DRIVING

Automatic application,
engine off
With the vehicle stationary, the park-
ing brake is automatically applied
when the engine is switched off.
The application of the parking brake
is confi rmed by:


-
the illumination of warning
lamp P
in control lever A

and in the instrument panel,

Automatic release

The electric parking brake releases
automatically and progressively

when you press the accelerator:


)
Manual gearbox
(fi rst gear or
reverse gear engaged): press
down fully on the clutch pedal
then press on the accelerator
pedal and move off.

)
Automatic gearbox
: accelerate
with the selector in position D
, M

or R
.

)
Electronic gearbox
: accelerate
with the selector in position A
, M

or R
.
Full release of the parking brake is
confi rmed by:


- the warning lamp P
in con-
trol lever A
and in the in-
strument panel going off,

- the display of a message "Parking
brake off" in the multifunction
screen.

When stationary, with the engine
running, do not press the acceler-
ator pedal unnecessarily, as you
may release the parking brake.


Maximum application

If necessary, you can use maximum
application
of the parking brake. It
is obtained by means of a long pull

on control lever A
, until you see the
message "Parking brake on" and an
audible signal is heard.

Maximum application is essential:



- when towing a caravan or a trail-
er, if the automatic functions are
activated but you are applying
the parking brake manually,

- when the gradient you are parked
on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),


- when towing, when loaded or
when parking on a gradient, turn
the front wheels towards the
pavement and engage a gear
when you park,

- after a maximum application, the
release time will be longer.

Before leaving the vehicle,
check that warning lamp P

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.
- the display of a message
"Parking brake on" in the multi-
function screen.

The normal operating sound will con-
fi rm to you the application/release of
the electric parking brake.

DRIVING

Emergency release
In the event of a malfunction of the
electric parking brake or the battery
running fl at, an emergency mecha-
nism can release the parking brake.


)
Immobilise the vehicle, with the
engine running, by engaging fi rst
gear (manual gearbox), posi-
tion P
(automatic gearbox) or M

or R
(6-speed electronic gearbox
system).

)
Switch off the engine, but leave
the ignition on.
If the vehicle cannot be immo-
bilised, do not do anything and
contact a CITROËN dealer or a
qualifi ed workshop without delay.

)
Fetch the vehicle blocks E
and
the release tool F
(handle) from
the toolbox.

)
If on a gradient: chock the vehi-
cle by placing the blocks in front
of or behind the front wheels, on
the falling side of the gradient.
If on level ground: chock the
vehicle by placing the blocks in
front of and behind one of the
front wheels.
)
Slide the front left-hand seat
back as far as possible.

)
Lift up the fl oor plug
B
on the
carpet in front of the seat.


)
Pierce the tab C
on the tube D

with the release tool F
.

)
Place the end of the handle F
in
the tube D
.

)
Turn the release tool F clock-
wise.
For safety reasons
, it is
essential
to continue turning the
device as far as it will go. The
parking brake is released.

)
Remove the release tool F
and
store it with the blocks E
in the
toolbox.



- The operation of the parking
brake reinitialises itself when
the ignition is switched off then
on again. If the reinitialisation of
the parking brake proves impos-
sible, contact a CITROËN dealer
or a qualifi ed workshop.

- The subsequent time required
for application may be longer
than during normal operation.

When the release tool F
is engaged, do not operate the control lever or the ignition switch.
Immobilisation of the vehicle is no longer assured once the manual emergency release has been used.
The emergency release system cannot be used to apply the parking brake mechanically.
Take care not to allow moisture or dust in the proximity of the plug.
For safety reasons, contact a CITROËN dealer or a qualifi ed workshop as soon as possible to have the plug replaced.
