Switching the system off
F Turn the air flow control to the left until all of the indicator
lamps go off.
This switch does not operate the air conditioning, only the air fan.
When the "REST" function is activated, you cannot modify the temperature, air flow
and distribution settings: these are controlled automatically according to the ambient
temperature.
This function is not available in the STOP mode of Stop & Start. Avoid prolonged operation in interior
air recirculation mode or driving for
long periods with the system off (risk of
misting and deterioration of air quality).
On switching on the engine

230 V / 50 Hz power socket
Connect only one device at a time to
the socket (no extension or multi-way
connector).
Connect only devices with class II
insulation (shown on the device).
As a safety measure, when electrical
consumption is high and when
required by the vehicle's electrical
system (particular weather conditions,
electrical overload...), the power supply
to the socket will be cut off; the green
warning lamp goes off.
A 230 V / 50 Hz socket (maximum power:
120

W) is fitted to the centre console.
To use the socket:

device (telephone charger, laptop

warmer...).
This socket works with the engine running, as
well as in STOP mode on Stop & Start.
In the event of a fault with the socket, the green
warning lamp flashes.
Have it checked by a CITROËN dealer or a
qualified workshop.

Automatic illumination of headlamps.
Dipping the headlamps
Turn the ring to place the desired symbol
against the mark.Sidelamps only.
Dipped or main beam headlamps.
Pull the stalk to switch between dipped and
main beam headlamps.
In the lighting off and sidelamps modes, the
driver can switch on the main beam headlamps
temporarily ("headlamp flash") by maintaining a
pull on the stalk.
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.
Travelling abroad
Halogen and xenon headlamps
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 on-
coming drivers.
Contact a CITROËN dealer or a
qualified workshop.

Windscreen and headlamp wash
F Pull the windscreen wiper stalk towards you. The windscreen wash then the
windscreen wipers operate for a fixed
period.
It operates only when the headlamps are off or
the vehicle is stationary.
Low screenwash / headlamp wash
fluid level
On vehicle fitted with headlamp washers, the
low level of this fluid is indicated by gauge in
the reservoir filler neck under the bonnet.
Checking and topping up this fluid can should
be done with the engine off.
The level of this fluid should be
checked regularly, particularly during
w i n t e r.
For more information on Checking the levels
and in particular the screenwash / headlamp
wash, refer to the corresponding section.
Associated with the windscreen wash, the
headlamp washers operate with the vehicle
moving, when the dipped or main beam
headlamps are on
.
To reduce the consumption of the fluid
by the headlamp washers, they operate
only with every seventh use of the
screenwash or every 25 miles (40 km)
during a given journey.

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-slip regulation (ASR)
and dynamic stability control
(DSC)
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 automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem. This is indicated by flashing of this
warning lamp in the instrument panel.
Intelligent traction control
system ("Snow motion")
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control .
This system detects situations of difficult
sur face grip that could make it difficult to move
off or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.

From approximately 12 mph (20 km/h),
this warning lamp flashes for two minutes
accompanied by an audible signal of increasing
volume. Once these two minutes have elapsed,
this warning lamp remains on until the one or
more rear passengers fasten their seat belt.
