Switching off the lighting when switching off the ignition

When the ignition is switched off, allof the lamps switch off immediately, except for the dipped beam headlamps if automatic guide-me-home lighting is activated.
Temporarily keeping the dipped beamheadlamps on after the vehicle's ignition has been switched off makes the driver's exit easier when the light is poor.

Switching on the lightingwhen switching on the ignition
To reactivate the lighting control stalk, turnthe ring Ato position A"0"
- lighting off, then to the position of your choice.
If the lighting is switched on manually after switching off the ignition, there is an audible signal when a front door is opened to warn the driver that they have forgotten to switchoff the vehicle's lighting, with the ignition off.
They switch off automatically after a periodwhich depends on the state of charge of thebattery (entry to energy economy mode).
Parking lamps
Side markers for the vehicle by illumination of
the sidelamps on the traffic side only.) Within one minute of switching off the
ignition, operate the lighting control stalk up
or down dependin
g on the traffic side(for example: when parking on the left;
lighting control stalk upwards; the right hand sidelamps are on).
This is confirmed by an audible signal and
illumination of the corresponding direction
indicator warning lamp in the instrument panel.
To switch o
ff the parking lamps, return the
lighting control stalk to the central position.

Cornering lighting
With dipped or main beams, this function makes use of the beam from a front foglamp to
illuminate the inside of a bend, when the vehicle
speed is below 25 mph (approximately 40 km/h)(urban driving, winding road, intersections,
parking manouevres...).

Ty r e u n d e r - i nfl 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 detectionsystem is an aid to driving which doesnot replace the need for the driver to bevigilant 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
si
gnal, to identify the wheel concerned.
The STOPwarning 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.

179Safety
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 theresistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.

















Trajectory control systems (ESP)
Anti-slip regulation (ASR)
and electronic stability
control (ESC)
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.

Activation
These systems are activated automaticallyeach time the vehicle is started.
They come into operation in the event of a gripor trajectory problem.
This is indicated b
y flashing of this
warning lamp in the instrument panel.

Intelligent traction control
s
ystem ("Snow motion")
Your vehicle has a system to help driving on snow: intelligent traction control.
This system detects situations of difficult surface adhesion that could make it difficult to
move off or make progress on deep fresh snowor compacted snow.
In these situations, the intelligent tractioncontrol limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly recommended on surfaces offering low levels of adhesion.

Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on softground...), if you are unable to make progress,it may be advisable to temporarily deactivate
these systems, so that the wheels can spinfreely and allow the vehicle to move.
) Press the "ESP OFF"
button,located near the steering wheel.

Reactivation
These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h).)
Press the "ESP OFF"
button again to
reactivate them manually.

Operating fault

The trajectory control systems offer increased safety in normal driving, butthis should not encourage the driver to take extra risks or drive at high speed.
The correct functioning of these systems is assured provided thatmanufacturer's recommendations areobserved on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair procedures.
After an impact, have these systems checked by a CITROËN dealer or a qualified workshop.
I
f this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, this
indicates a fault with these systems.
Have it checked by a CITROËN dealer or aqualified workshop.
It is recommended that the systems bereactivated as soon as possible.
If this warnin
g lamp comes on in the instrumentpanel and the indicator lamp in the buttoncomes on, this indicates that these systems aredeactivated.
