Safety
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems checked by a CITROËN dealer or a
qualified workshop.
Intelligent traction control
("Snow motion")
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control.
This system detects situations of poor surface
grip that could make it difficult to move off
or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control for
your vehicle.
The use of snow tyres is strongly recommended on surfaces offering low
levels of grip.
For technical reasons, in particular to
improve the quality of telematic services
for customers, the Manufacturer reserves the
right to carry out updates to the vehicle's
on-board telematic system at any time.
If you benefit from the Citroën Connect
Box offer with the SOS and Assistance
Pack included, there are additional services
available to you in your personal space, via
the website for your country.
For information about the SOS and
Assistance Pack, please refer to the general
conditions for these services.
Electronic stability control
(ESC)
Electronic stability control programme
comprising the following systems:
–

Anti-lock Braking System (ABS) and Electronic
Brake Force Distribution (EBFD).
–


Emergency braking assistance (EBA).
–


Anti-slip regulation (ASR).
–


Dynamic stability control (DSC).
–


T
railer stability assist (TSA).
Definitions
Anti-lock braking system (ABS) and electronic brake force distribution
(EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control in
corners, in particular 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 (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 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 braking efficiency.
Anti-slip regulation (ASR)
This system optimises traction in order to avoid
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, this system 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.
Trailer stability assist (TSA)
This system allows control of the vehicle to be
retained when towing a trailer, so as to avoid the
risk of snaking.
Anti-lock braking system (ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning lamp
signals that there is a fault with the ABS.
The vehicle retains conventional braking. Drive
carefully at moderate speed.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
Illumination of this warning lamp, coupled
with the STOP and ABS warning lamps,
accompanied by the display of a message and
an audible signal, signals that there is a fault with
the electronic brake force distribution (EBFD).
You must stop as soon as it is safe to do so.
Call a CITROËN dealer or a qualified workshop.

82
Safety
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. 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 belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
Operation
Switching on
By default, the system is not selected.
The state of the function is not saved when the
ignition is switched off.
The driver can select the system when the
engine is running, when the vehicle is stationary
or when moving at speeds up to approximately
31 mph (50
km/h).




With instrument panels with dials► To select the system, at speeds below
31 mph (50 km/h), press this button until
its indicator lights up; this lamp appears in green
in the instrument panel.
The system becomes active at speeds below 19
mph (30
km/h).
With digital instrument panel
► To select the system, at speeds below
31 mph (50 km/h), press this button until
its green indicator lamp comes on; this lamp
appears in grey in the instrument panel.
► The system becomes active at speeds
below 19 mph (30 km/h); this indicator
lamp comes on in green in the instrument panel.
►

When the vehicle begins its descent, you can
release the accelerator and brake pedals; the
system regulates the speed:
– if the gearbox is in first or second gear ,
the speed decreases and the
indicator
lamp flashes rapidly,
–

if the gearbox is in neutral or if the clutch pedal
is depressed, the speed decreases and the
indicator

lamp flashes slowly; in this case, the
maintained descent speed is lower.
On a descent, with the vehicle stationary, if you
release the accelerator and brake pedals, the
system will release the brakes to set the vehicle
gradually in motion.
The brake lamps light up automatically when the
system is regulating.
If the speed exceeds 19 mph (30
km/h),
regulation is paused automatically, the
indicator
lamp goes back to grey in the
instrument panel, but the green indicator lamp in
the button remains on.
Regulation resumes automatically when the
speed falls below 19 mph (30
km/h) again, if the
slope and pedal release conditions are met.
You can depress the accelerator or brake pedal
again at any time.
Switching off
► Press the button until its indicator lamp goes
off; the indicator lamp on the instrument panel
goes off.
At speeds above 43 mph (70
km/h), the system
is automatically deactivated; the indicator lamp in
the button goes off.
Malfunction
If a fault occurs with the system, a message is
displayed in the instrument panel.
Have it checked by a CITROËN dealer or a
qualified workshop.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.

Safety
– a child or an animal in a vehicle which is
exposed to the sun, with the windows closed,
– the keys within reach of children inside the
vehicle.
Child seat at the front

► Adjust the front passenger seat to the
highest and fully back longitudinal position ,
with the backrest straightened.
"Rearward facing"

The front passenger airbag must be deactivated. Otherwise, the child risks
being seriously injured or killed if the
airbag is deployed .
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
Such work must only be done by a CITROËN
dealer or a qualified workshop.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Child seats
The legislation on carrying children is specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
–

In accordance with European regulations, all
children under the age of 12 or less than one
and a half metres tall must travel in approved
child seats suited to their weight , on seats
fitted with a seat belt or ISOFIX mountings.
–


Statistically
, the safest seats in your
vehicle for carrying children are the rear
seats.
– A child weighing less than 9 kg must travel
in the "rearward facing" position both in the
front and in the rear.
It is recommended that children travel
on the rear seats of the vehicle:
–

"rearward facing" up to the age of 3,
–

"forward facing" over the age of 3.
Make sure that the seat belt is correctly
positioned and tightened.
For child seats with a support leg, ensure that
the support leg is in firm and steady contact
with the floor.
Advice
An incorrectly installed child seat compromises the child's safety in the
event of an accident.
Ensure that there is no seat belt or seat belt
buckle under the child seat, as this could
destabilise it.
Remember to fasten the seat belts or the
harness of child seats, keeping the slack
relative to the child's body to a minimum,
even for short journeys.
When installing a child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it secures
the child seat firmly on the seat of the vehicle.
If the passenger seat is adjustable, move it
forwards if necessary.
Remove the head restraint before
installing a child seat with a backrest on a
passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event of
sharp braking. Refit the head restraint once
the child seat has been removed.
Children at the rear
A child seat with ISOFIX or i-Size
mountings must never be installed on the
centre rear passenger seat.
Installing a booster seat
The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
Use a booster seat with backrest, equipped
with a belt guide at shoulder level.
Additional protections
To prevent accidental opening of the
doors and rear windows, use the "Child lock".
Take care not to open the rear windows by
more than one third.
To protect young children from the rays of the
sun, fit side blinds on the rear windows.
As a safety precaution, do not leave:
–

a child alone and unattended in a vehicle,

charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, which secret code must be
recognised in order for starting to be possible.
