Braking assistance systems
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).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and manoeuvrability of your vehicle when braking, in par ticular 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.
When braking in an emergency, press very firmly without releasing the pressure.
Operating fault
If this warning lamp comes on, together with the STOP and ABSwarning lamps, accompanied by an audible signal and a message in the multifunction screen, it indicates a malfunction of 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.
When replacing wheels (tyres and rims), ensure that they conform to the manufacturer's recommendations.
If this warning lamp comes on, accompanied by an audible signal and a message in the multifunction screen, it indicates a malfunction of the anti-lock braking system which could result in loss of control of the vehicle when braking.
In either case, contact 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 shor t journeys. Do not interchange the seat belt buckles as they will not fulfil their role fully. The seat belts are fitted with an iner tia 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 par t of the strap must be positioned as low as possible on the pelvis. The upper par t must be positioned in the hollow of the shoulder. The iner tia 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 firmly on the strap and
releasing it so that it reels in slightly.
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 conver ted or modified to avoid affecting its per formance. In accordance with current safety regulations, for all repairs on your vehicle, 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, par ticularly 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 shor ter 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.
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 car tridge 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.

181Safety
Airbags
System designed to maximise the safety of the occupants (with the exception of the rear centre passenger) in the event of violent collisions. It supplements the action of the force-limiting seat belts (with the exception of the rear centre passenger). 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); 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 cer tain 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 the same or a subsequent accident), the airbag will not be deployed again.
Impact detection zones
A. Front impact zone. B. Side impact zone.
Deployment of the airbag(s) is
accompanied 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 sensitive individuals may experience slight irritation. The noise of the detonation may result in a slight loss of hearing for a shor t time.

Stop & Start The Stop & Star t system puts the engine temporarily on standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as y ou want to move off. The restar t takes place instantly, quickly and silently. Per fect for urban use, the Stop & Star t system reduce s fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With the automatic gearbox system, for your comfor t during parking maoeuvres, STOP mode is not available for a few seconds after coming out of reverse gear. STOP mode does not affect the functionality of the vehicle, such as braking, power steering, for example.
Never refuel with the engine in STOP mode; you must switch off the ignition with the key.
The "ECO" warning lamp comes on in the instrument panel and the engine goes into standby:
- with a manual gearbox , at speeds below 12 mph (20 km/h), when you put the gear lever into neutral and release the clutch pedal, - with the 6-speed electronic gearbox system , at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the gear lever into position N .
If your vehicle is fitted with the system, a time counter calculates the sum of the periods in STOP mode during a journey. It resets itself to zero every time the ignition is switched on with the key.
STOP mode is not invoked when: - the driver's door is open, - the driver's seat belt is not fastened, - the vehicle has not exceeded 6 mph (10 km/h) since the last engine start using the key, - the electric parking brake is applied or being applied, - the engine is needed to maintain a comfor table temperature in the passenger compar tment, - demisting is active, - some special conditions (battery charge, engine temperature, braking assistance, ambient temperature...) where the engine is needed to assure control of a system.
Special cases:STOP mode unavailable
In this case, the "ECO" warning lamp flashes for a few seconds, then goes off. This operation is per fectly normal.
