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 system to aler t other road users to an imminent danger.  Press the central par t of the steering wheel with integrated controls.
Use the horn moderately and only in the following circumstances: - immediate danger, - over taking a cyclist or pedestrian, - approaching a location lacking 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.

Tyre under-infl ation detection
System which automatically and continuously checks the pressure of the tyres while driving. Sensors fitted in each valve trigger a warning in the event of problem (speed above 12 mph (20 km/h)).
Puncture
The tyre under-inflation detection system is an aid to driving which does not replace the need for the driver to be vigilant or to drive responsibly.
Under-infl ated tyre
This warning lamp is displayed on the instrument panel and/or a message appears in the screen, accompanied by an audible
signal, to identify the wheel concerned.
The STOP warning lamp comes on and/or this warning lamp is displayed on the instrument panel, accompanied by
an audible signal and a message in the screen identifying the wheel concerned.
 Stop as soon as it is safe to do so, avoiding any sudden movement of the steering wheel and the brakes.  Repair or change the damaged wheel (punctured or very deflated tyre), and have the tyre pressure checked as soon as possible.
 Check the tyre pressures as soon as possible. This check must be carried out when the tyres are cold.

173Safety
Sensor(s) not detected or faulty
A message appears in the screen, accompanied by an audible signal, to identify the wheel or wheels which are not detected or
to indicate a fault in the system. Contact a CITROËN dealer or a qualified workshop to replace the faulty sensor(s).
All repairs and changing of tyres on a wheel fitted with this system must be carried out by a CITROËN dealer or a qualified workshop.
If, when changing a tyre, you install a wheel which is not detected by your vehicle (example: fitting of snow tyres), you must have the system reinitialised by a CITROËN dealer or a qualified workshop.
This system does not avoid the need to have the tyre pressures checked regularly (refer to the "Identification markings" section) to ensure that
the optimum dynamic per formance of the vehicle is maintained and prevent premature wear of the tyres, par ticularly in arduous driving conditions (heavy load, high speed). The tyre pressures must be checked cold, at least once a month. Remember to check the pressure of the spare wheel. The tyre under-inflation detection system may experience temporary inter ference due to electro-magnetic emissions on a frequency close to that used by the system.
This message is also displayed when one of the wheels is away from the vehicle (being repaired) or when one or more wheels without a sensor are fitted. If your vehicle is equipped with a spare
wheel, this is not fitted with a sensor.

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.
