Lighting control
In some weather conditions (e.g. low 
temperature or humidity), the presence 
of misting on the internal sur face of the 
glass of the headlamps and rear lamps is 
normal; it disappears after the lamps have 
been on for a few minutes.
If one or more lamps fails, a message 
asks you to check the lamp or lamps 
concerned.
Travelling abroad
If planning to use your vehicle in a country 
that drives on the other side of the road, 
the headlamp dipped beams must be 
adjusted to avoid dazzling oncoming 
drivers. Contact a CITROËN dealer or a 
qualified workshop.

Front and rear foglamps
They operate with the sidelamps 
or dipped beam headlamps on, in 
manual or auto mode.In good or rainy weather, by day and night, 
using the front foglamps and the rear 
foglamp is prohibited. In these situations, 
the power of their beams may dazzle other 
drivers. They should only be used in fog or 
falling snow.
In these weather conditions, it is your 
responsibility to switch on the foglamps 
and dipped beam headlamps manually as 
the sunshine sensor may detect sufficient 
light.
Do not forget to turn off the front foglamps 
and the rear foglamp as soon as they are 
no longer necessary.
Switching off of the lighting when the 
ignition is switched off 
On switching off the ignition, all of the 
lamps turn off immediately, except for 
dipped beam if automatic guide-me-home 
lighting is activated. Switching on the lighting after the 
ignition is switched off 
To reactivate the lighting control, set 
the ring to "
AUTO", then to the desired 
position.
On opening the driver's door a temporary 
audible signal warns the driver that the 
lighting is on.
It will go off automatically after a period of 
time that depends on the state of charge 
in battery (entering energy-saving mode).

and a low level of ambient light is detected 
by a sunshine sensor, the number plate 
lamps,
 
sidelamps and dipped beam headlamps 
are switched on automatically, without any 
action on the part of the driver. They can also 
come on if rain is detected, at the same time as 
automatic operation of the windscreen wipers.
As soon as the brightness returns to a 
sufficient level or after the windscreen wipers 
are switched off, the lamps are switched off 
automatically.
Malfunction

 ehicles at the top or bottom of a 
steep slope, on winding roads, on 
crossroads.
Headlamp adjustment
To avoid causing a nuisance to other road 
users, the height of the headlamp beams 
should be adjusted according to the load in the 
vehicle.
0. Driver only or driver + front passenger.
1. Driver + front passenger + rear 
passengers + maximum authorised load. The initial setting is position 0.
Cornering lighting
If your vehicle is equipped with it, this system 
makes use of the beam from a front foglamp 
to illuminate the inside of a bend, when the 
main or dipped beam headlamps are on and 
the vehicle speed is below 25 mph (40 km/h) 
(urban driving, winding road, junctions, parking 
manoeuvres, etc.).
Clean the windscreen regularly, 
particularly the area in front of the camera.
The internal sur face of the windscreen can 
also become misted around the camera. 
In humid and cold weather, demist the 
windscreen regularly.
Do not allow snow to accumulate on the 
bonnet or roof of the vehicle as this could 
mask the camera's view.

In case of towing
Driving with a trailer places greater 
demands on the towing vehicle and 
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the 
temperature of the coolant.
As the fan is electrically controlled, its cooling 
capacity is not dependent on the engine speed.
F
 
T
 o lower the engine speed, reduce your 
speed.
The maximum towable load on an incline 
depends on the gradient and the exterior 
temperature.
In all cases, keep a check on the coolant 
temperature.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of 
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing  vehicle and of the trailer, observing the 
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height 
of your vehicle. If the exterior temperature is high, it is 
recommended that the engine be allowed 
to idle for 1 to 2
  minutes after the vehicle 
comes to a stop, to facilitate its cooling.
F
 
I
f this warning lamp and the 
STOP warning lamp come on,

the engine as soon as possible. New vehicle
Do not pull a trailer before having driven at 
least 600
  miles (1,000   kilometres).
For more information on Headlamp 
adjustment , refer to the corresponding 
section.
The rear parking sensors will be 
deactivated automatically to avoid the 
audible signal if a genuine CITROËN 
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has 
a secret code. When the ignition is switched 
on, this code must be recognised in order for 
starting to be possible.
A few seconds after switching off the ignition, 
this system locks the engine control system, 
therefore preventing the engine from being 
started in the event of a break-in.
If the system fails, as reported by a message, 
the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons, 
never leave your electronic key in the 
vehicle, even when you are close to it.
It is recommended that you keep it with 
you.

Never leave the engine running in 
an enclosed area without adequate 
ventilation: internal combustion engines 
emit toxic exhaust gases, such as carbon 
monoxide. There is a risk of intoxication 
and death!
In very extreme wintry conditions 
(temperature below -23°C), to guarantee 
correct operation and the longevity of 
the mechanical elements of your vehicle,
