Electronic stability control (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 contributes towards improved control on
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The EBFD manages the braking pressure
wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered according 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-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control
(DSC)
If there is a difference between the path
followed by the vehicle and that required by
the 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.

Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
In emergency braking, press ver y
firmly and maintain this pressure. When changing wheels (tyres and
rims), ensure that these are approved
for your vehicle.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
The fixed illumination of this warning
lamp indicates that there is a fault
with the ABS.
The vehicle retains conventional
braking. Drive carefully at moderate
speed.
When this warning lamp comes on,
coupled with the STOP and ABS
warning lamps, accompanied by
an audible signal and a message,
it indicates that there is a fault
with the electronic brake force
distribution (EBFD).
You must stop as soon as it is
safe to do so.
In both cases, have the system
checked by a CITROËN dealer or
a qualified workshop as soon as
possible.
Intelligent traction
control
If fitted to your vehicle, it has a system to help
driving on snow: intelligent traction control .
This system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, intelligent traction
control limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of grip.

Activation
These systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation
of the engine and brakes.This is indicated by flashing of this
warning 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.
But it is recommended that the system be
reactivated as soon as possible.

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 observation of the
manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the CITROËN
assembly and repair procedures.
After an impact, have the system
checked by a CITROËN dealer or a
qualified workshop.If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, this
indicates a fault with the system.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.

Grip control
Special patented traction control system which
improves traction on snow, mud and sand.
This system, the operation of which has been
optimised for each situation, allows you to
manoeuvre in most conditions of poor grip
(encountered during touring use).This mode is calibrated for a low level of wheel
spin, based on the different levels of grip
normally encountered on the road.

of grip encountered for each of the two front
wheels on moving off.
(mode active up to 30 mph (50 km/h))
F

A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.
An indicator lamp associated with each mode
comes on to confirm your choice. The accelerator pedal should be pressed
sufficiently to allow the system to use the power
of the engine. Operation at high engine speeds
is completely normal. Different modes are provided:Snow
Standard (ESC)
Every time the ignition is switched off,
the system automatically resets to this
mode.
Associated with all-seasons Peak
Mountain Snow Flake tyres, this system
offers a compromise between safety,
adhesion and traction. These tyres work
equally well in winter and summer.

This mode, when moving off, allows
considerable spin on the wheel with the least
grip to optimise clearing of the mud and regain
grip. At the same time, the wheel with the most
grip is controlled in such a way as to transmit
as much torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 50 mph (80 km/h))F

P
lace the knob in this position. This mode allows little spin on the two driving
wheels at the same time to allow the vehicle to
move for ward and limit the risks of getting stuck
in the sand.

grass, ...) Sand
Driving advice
Your vehicle is designed principally to
drive on tarmac roads but it allows you
to drive on other less passable terrain
occasionally.
However, it does not permit off-road
driving such as:
-

c
rossing and driving on terrain
which could damage the underbody
or strip away components (fuel
pipe, fuel cooler...) due to obstacles
or stones in particular,
-

d
riving on terrain with steep
gradients and poor grip,
-

c
rossing a stream.

Advice
In the event of an impact
Depending on the nature and
seriousness of the impact, the
pretensioning device may be deployed
before and independently of the airbags.
Deployment of the pretensioners is
accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
In all cases, the airbag warning lamp
comes
on.
Following an impact, have the seat belts
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
In order to be effective, a seat belt must:
-

b

e tightened as close to the body as
possible,
-

b

e pulled in front of you with a smooth
movement, checking that it does not
twist,
-

b

e used to restrain only one person,
-

n

ot bear any trace of cuts or fraying,
-

n

ot be converted or modified to avoid
affecting its performance.
In accordance with current safety
regulations, for all repairs on your vehicle's
seat belts, go to a qualified workshop with
the skills and equipment needed, which a
CITROËN dealer is able to provide.
Have your seat belts checked regularly by
a CITROËN dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy
water or a textile cleaning product, sold by
CITROËN dealers.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Recommendations for
children
Use a suitable child seat if the passenger is
less than 12 years old or shorter than one
and a half metres.
Never use the same seat belt to secure more
than one person.
Never allow a child to travel on your lap.
For more information on Child seats , refer
to the corresponding section.
The driver must ensure that passengers use
the seat belts correctly and that they are all
fastened before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do not interchange the seat belt buckles as
they will not fulfill their role fully.
The seat belts are fitted with an inertia reel
permitting automatic adjustment of the
length of the strap to your size. The seat belt
is stowed automatically when not in use.
Before and after use, ensure that the seat
belt is reeled in correctly.
The lower part of the strap must be
positioned as low as possible on the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
The inertia reels are fitted with an automatic
locking device which comes into operation in
the event of a collision, emergency braking
or if the vehicle rolls over. You can release
the device by pulling the strap firmly and
then releasing it so that it reels in slightly.

Airbags
System designed to contribute towards
improving the safety of the occupants (with the
exception of the centre seat in rows 2 and 3, if
so equipped) in the event of violent collisions.
The airbags supplement the action of the seat
belts fitted with force limiters.
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
-
i
n the case of a serious impact, the airbags
are deployed instantly and contribute
towards better protection of the occupants
of the vehicle (with the exception of
the centre seat in rows 2 and 3, if so
equipped); immediately after the impact,
the airbags deflate rapidly so that they
do not hinder visibility or the exit of the
occupants,
-

i
n the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
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 the
same or a subsequent accident), the
airbag will not be deployed again.
Deployment of one or more of the
airbags is accompanied by a slight
emission of smoke and a noise, due
to the activation of the pyrotechnic
cartridge incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience slight
irritation.
The noise of detonation related to the
deployment of one or more airbags may
result in a slight loss of hearing for a
short time.
