Installing ISOFIX child seats
In accordance with European regulations, this table indicates the options for the installation of ISOFIX c hild seats on the vehicle seats fitted with ISOFIX mountings. In the case of the universal and semi-universal ISOFIX child seats, the child seat's ISOFIX size categor y, determined by a letter between A and G , is indicated on the child seat next to the ISOFIX logo.
IUF: seat suitable for the installation of an I sofix U niversal seat, " F or ward facing" and secured using the "Top Tether" up per strap. IL- SU: seat suitable for the installation an I sofix S emi- U niversal seat which is: - "rear facing" fitted with a "Top Tether" upper strap or a stay, - "for ward facing" fitted with a stay, For the securing of the "Top Tether" upper strap, ref er to the "ISOFIX Mountings" section. X: seat which is not suitable for the installation of an ISOFIX seat of the size category indicated.
* Infant car seats and "car cots" cannot be installe d on the front passenger seat.

Direction indicators
Selection of the left or right direction indicators to signal a change of direction of the vehicle.  Left: lower the lighting stalk beyond the point of resistance.
 Right: raise the lighting stalk beyond the point of resistance.
"Motorway" function
 Press briefly upwards or downwards, without going beyond the point of resistance; the direction indicators will flash 3 times.
Hazard warning lamps
A visual warning by means of the direction indicators to aler t other road users to a vehicle breakdown, towing or accident.  Press this button, the direction indicators
flash. They can operate with the ignition off.

SOS
131Safety
Automatic operation of
hazard warning lamps
When braking in an emergency, depending on the deceleration, the hazard warning lamps come on automatically. They switch off automatically the first time you accelerate.  You can also switch them off by pressing the button.
Horn
Audible warning to aler t other road users to an imminent danger.  Press one of the spokes of the steering wheel.
Use the horn moderately and only in the following cases: - immediate danger, - over taking a cyclist or pedestrian - when approaching an area where there is no visibility.
Emergency or
assistance call
This system allows you to make an emergency or assistance call to the emergency ser vices or to the dedicated CITROËN ser vice. For more information on the use of this function, refer to the "Audio and telematics" section.

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 on 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 on 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.

133Safety
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.
When braking in an emergency, press firmly without releasing the pressure.
Trajectory control systems
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid 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 programme 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.
Activation
These systems are activated automatically each time the vehicle is star ted. They come into operation in the event of a grip or trajectory problem.
This is indicated by flashing of this warning lamp on the instrument panel.
