Braking assistance systems
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 sur faces.
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
If this warning lamp comes on, 
accompanied by an audible signal 
and a message in the instrument 
panel screen, it indicates a fault with 
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 
instrument panel screen, it indicates a fault with 
the electronic 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 both cases, contact a CITR oËn dealer or a 
qualified workshop.
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 efficiency.
Group of supplementary systems which help 
you to obtain optimum braking in complete 
safety in emergency situations:
- 
anti-lock braking system (ABS),
-  electronic brake force distribution (EBFD),
-  emergency braking assistance (EBA).
When replacing wheels (tyres and 
rims), ensure that they conform to the 
manufacturer's recommendations.When braking in an emergency, press 
firmly without releasing the pressure.
When braking in an emergency, 
press very firmly without releasing 
the pressure.

Trajectory control systems
Anti-slip regulation (ASR) and dynamic stability  
control (DSC)
Activation
This is indicated by flashing of this 
warning lamp in the instrument panel.
Your vehicle has a system to improve traction 
on snow: intelligent traction control
.
This system detects situations of low adhesion 
that might make moving off and progress 
difficult on deep fresh snow or compacted 
snow.
In these situations the intelligent traction 
control  system regulates the amount of wheel 
slip to optimise the traction and trajectory 
control of your vehicle.
For vehicles with Hydractive III + suspension, 
manual adjustment of ground clearance to 
the intermediate position improves further the 
ability to make progress in deep snow (see the 
relevant paragraph).
The anti-slip regulation (also known as traction 
control) optimises traction to prevent skidding 
of the wheels, by acting on the brakes of the 
driving wheels and on the engine.
The electronic stability control 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.
Intelligent traction control 
system ("Snow motion")
These systems are activated automatically 
each time the vehicle is started.
They come into operation in the event of a grip 
or trajectory problem.
The use of snow tyres is strongly 
recommended on sur faces with low 
adhesion.

Reactivation
Operating fault
Illumination of this warning lamp and 
the lamp in the deactivation button, 
accompanied by an audible signal 
and a message, indicate a fault with 
the system.
Deactivation
Reactivate the systems as soon as the level of 
grip permits.
F Press this button.
The indicator lamp in the button 
comes on.
Contact a CITROËN dealer or a qualified 
workshop to have the system checked.
The DSC and ASR systems no longer act 
on the operation of the engine and on the 
brakes in the event of a involuntary change of 
trajectory.
F 
Press this button again.
The indicator lamp in the button 
goes off.
The systems are reactivated automatically 
each time the ignition is switched back on or 
from 30 mph (50 km/h).
Below 30 mph (50 km/h), you can reactivate 
them manually:
In exceptional conditions (starting a vehicle 
which is bogged down, stuck in snow, on soft 
ground...), it may be advisable to deactivate 
the d
SC and a SR, so that the wheels can turn 
freely and regain grip.

DSC/ASR
The DSC and ASR systems offer increased 
safety in normal driving, but they should not 
encourage the driver to take extra risks or 
drive at high speed.
It is in conditions of reduced grip (rain, 
snow, black ice) that the risk of loss of grip 
increases. It is therefore important for your 
safety to keep the DSC and ASR systems 
activated in all conditions, and particularly 
in difficult conditions.
The correct operation of these systems 
depends on observation of the 
manufacturer's recommendations regarding 
as much the wheels (tyres and rims), 
braking and electronic components as the 
assembly and repair procedures used by 
CITROËN dealers.To benefit in full from the effectiveness 
of the DSC and ASR systems in wintry 
conditions, the vehicle must be fitted with 
four snow tyres, allowing the the vehicle to 
retain neutral handling on the road.
After an impact, have these systems 
checked by a CITROËN dealer or a 
qualified workshop.

Seat belts
Front seat belts
Fastening
F Pull the belt down in front of you in a steady 
movement, making sure that it does not 
become twisted.
F  Press the fastening into its buckle.
F  Check that it is properly secured and that 
the automatic locking mechanism operates 
correctly by pulling sharply on the belt 
strap.
F  The lap strap should be positioned as low 
down as possible in the lap and as tight as 
possible.
F  The diagonal strap should be positioned 
across the chest and away from the neck.
Each belt has a reel that adjusts its length 
automatically to the girth of the seat occupant.
The front seat belts are fitted with a 
pretensioning system and force limiter.
This system improves safety in the front seats 
in the event of a front impact.
Depending on the seriousness of the impact, 
the pretensioning system instantly tightens the 
seat belt against the body of the occupant. The pretensioning seat belts are active when 
the ignition is on.
The force limiter reduces the pressure of the 
seat belt against the chest of the occupant,  
so increasing his protection.
Height adjustment

Advice
In order to be effective, a seat belt must:
- be tightened as close to the body as 
possible,
-  be pulled in front of you with a smooth 
movement, checking that it does not 
twist,
-  be used to restrain only one person,
-  not bear any trace of cuts or fraying,
-  not be converted or modified to avoid 
affecting its performance.
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, refer to the "Child 
seats" section.
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.
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.
The driver must ensure that passengers use 
the seat belts correctly and that they are all 
restrained securely 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 fulfil 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.
b
efore 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 rear centre passenger) 
in the event of a violent collision. The airbags 
supplement 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 contribute 
towards best protecting the occupants of 
the vehicle (with the exception 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 in 
certain roll-over conditions, the airbags 
may not be deployed; the seat belt alone 
contributes towards your protection in 
these situations.
Impact detection zones
A. Front impact zone.
B.  Side impact zone.
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 deployment of airbag will not be 
triggered again. Deployment of one or more 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 the detonation related to 
the deployment of one or more airbags 
may result in a slight loss of hearing for 
a short time.

Front airbags
Deployment
The airbags are deployed, except the 
passenger's front airbag if it is deactivated, in the 
event of a serious front impact to all or part of the 
front impact zone A, in the longitudinal centreline 
of the vehicle on a horizontal plane and directed 
from the front to the rear of the vehicle.
The front airbag inflates between the chest and 
head of the front occupant of the vehicle and the 
steering wheel, drivers side, and the dashboard, 
passenger's side to cushion their for ward 
movement. This warning lamp comes on in the 
screen located in the roof console 
when the ignition is on and until the 
airbag is reactivated.
Deactivation
Only the front passenger's airbag can be 
deactivated:
F 
with the ignition off , insert the key in the 
passenger airbag deactivation switch 1 ,
F  turn it to the "OFF"  position,
F  then, remove the key keeping the switch in 
this position. To assure the safety of your child, the 
passenger's airbag must be deactivated 
when you install a rear ward facing child 
seat on the front passenger seat.
Other wise, the child would risk being 
seriously injured or killed if the airbag 
were deployed.
Reactivation
When you remove a rear ward facing child seat, 
turn switch 1 to the "ON"
 position to reactivate 
the airbag and so assure the safety of your 
front passenger in the event of an impact.
System which contributes towards the 
protection of the head and chest of the driver 
and front passenger in the event of a front 
impact.
The driver's airbag is fitted in the centre of the 
steering wheel; the front passenger's airbag is 
fitted in the dashboard above the glove box.
