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.

No aler t will be given in the following situations: - in the presence of stationary objects (parked vehicles, barriers, street lamps,
road signs...), - with vehicles moving in the opposite direction, - driving on a sinuous road or a sharp corner,
The aler t is given by a warning lamp which comes on in the door mirror on the side in question as soon as a vehicle - car, lorry, cycle - is detected and the following conditions are fulfilled: - all the vehicles must be moving in the same direction, - the speed of your vehicle is between 6 and 75 mph (10 and 140 km/h), - the difference in speed between your vehicle and the other vehicles must be less than 9 mph (15 km/h), - the traffic must be flowing normally, - in the case of an over taking manoeuvre, if this is prolonged and the vehicle being over taken remains in the blind spot, - you are driving on a straight or lightly cur ved road, - your vehicle is not pulling a trailer, a
caravan...
- when over taking (or being over taken by) a very long vehicle (lorry, coach...) which is at the same time detected at the rear in the
blind spot angle and present in the driver's for ward field of vision, - in very heavy traffic: vehicles detected in front and behind are confused with a lorry or a stationary object, - when over taking quickly.

Changing a bulb
The headlamps are fitted with polycarbonate glass with a protective coating:  do not clean them using a dr y or abrasive cloth, nor with a detergent or solvent product, use a sponge and soapy water,  when using a high pressure washer on persistent marks, do not direct at the lamps or their outlines for too long, so as not to damage their protective coating and seals.
 Do not touch the bulb directly with your fingers, use lint-free cloths. Changing a bulb should only be done after the headlamp has been switched off for a few minutes (risk of serious burns). It is imperative to use only anti-ultraviolet (UV) type bulbs in order not to damage the headlamp. Always replace a failed bulb with a new bulb with the same type and specification.
Risk of electrocution
Xenon bulbs (D1S-35W) must be replaced by a CITROËN dealer or a qualified workshop.
Bulbs with lugs, type H1, H7... take care to position them correctly to ensure the best lighting.

Towing a trailer, a caravan, etc.
Towbar suitable for the attachment of a trailer or caravan with additional lighting and signalling. Your vehicle is primarily designed for transpor ting people and luggage, but it may
also be used for towing a trailer.
We recommend the use of genuine CITROËN towbars and their harnesses that have been tested and approved from the design stage of your vehicle, and that the fitting of the towbar is entrusted to a CITROËN dealer or a qualified workshop. If the trailer is not fitted by a CITROËN dealer, it is imperative that it is fitted using the vehicle's electrical pre-equipment, in accordance with the manufacturer's instructions.
Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.
