Instruments

This system automatically and progressively
changes between the day and night uses by
means of a sensor, which measures the light
from the rear of the vehicle.In order to ensure optimum visibility during
your manoeuvres, the mirror lightens
automatically when reverse gear is
engaged.
Ventilation
Air intake
The air circulating in the passenger
compartment is filtered and originates either
from the outside via the grille located at the
base of the windscreen or from the inside in air
recirculation mode.
Air treatment
The incoming air follows various routes
depending on the controls selected by the
driver:
-

d
irect arrival in the passenger compartment
(air intake),
-
p

assage through a heating circuit (heating),
-

p
assage through a cooling circuit (air
conditioning).
Control panel
The controls of this system are
accessible in the " Air conditioning"
menu of the touch screen A .
Air distribution
The demisting/defrosting controls for the
windscreen and rear screen are located below
the touch screen.
1.Windscreen demisting/defrosting vents.
2. Front side window demisting/defrosting
vents.
3. Adjustable side air vent (driver only).
4. Central adjustable air vents.
5. Air outlets to the front footwells.
6. Air outlets to the rear footwells.

F Press button 5 to activate/deactivate the air conditioning system.
When the indicator lamp is on, the air
conditioning function is activated.
The air conditioning does not operate
when the air flow adjustment is inhibited.
Switching the system off
F Press this button; the indicator lamp in the button comes on.
This action switches off all of the functions of
the system.
The temperature is no longer controlled.
However, a slight flow of air, due to the
movement of the vehicle, can still be felt.
Pressing any button reactivates the system with
the settings that were previously in use. Avoid driving for long periods with
the system off – Risk of misting and
deterioration of air quality!
Automatic air conditioning
The air conditioning operates with the engine
running, but the ventilation and its controls are
available with the ignition on.
Operation of the air conditioning and regulation
of temperature, air flow and air distribution in
the passenger compartment are automatic.

Ventilation function with the
ignition on
When the ignition is switched on, you can
use the ventilation system to adjust the air
flow settings and the air distribution in the
passenger compartment for a duration which
depends on the battery charge.
This function does not operate the air
conditioning.
Switching the system off
F Press this button; the indicator lamp in the button comes on.
This action switches off all of the functions of
the system.

Avoid driving for long periods with
the system off – Risk of misting and
deterioration of air quality!
Recirculation of interior air
The intake of exterior air helps avoid and
eliminate misting of the windscreen and side
windows.
Recirculation of the interior air isolates the
passenger compartment from exterior odours
and fumes.When so required, this function also
allows faster heating or cooling of the air
in the passenger compartment.
F

or to permit the intake of outside air.
Avoid the prolonged use of interior
air recirculation – Risk of misting and
deterioration of air quality!

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 towed load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible. New vehicle
Do not pull a trailer before having driven at
least 620 miles (1,000 kilometres).
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.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing device is used. 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.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised to enable
vehicle start.
This electronic engine immobiliser locks
the engine management system a moment
after the ignition is switched off and prevents
unauthorised engine starting.
In the event of a fault, you are
informed by the illumination of this
warning lamp, an audible signal and
a message in the screen.
In this case, your vehicle will not start; contact
a CITROËN dealer or a qualified workshop as
soon as possible.
For safety and theft protection reasons,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with
you.

top your vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.
Avoid driving with snow chains on roads
that have been cleared of snow to avoid
damaging your vehicle's tyres and the
road sur face. If your vehicle is fitted with
alloy wheels, check that no part of the
chain or its fixings is in contact with the
wheel rim. Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Very cold climate screens
Removable protective screens which prevent
the accumulation of snow at the radiator
cooling fan.
Before fitting or removing a screen,
ensure that the engine is off and the
cooling fan has stopped.
It is recommended that the screens be
fitted and removed by a CITROËN dealer
or a qualified workshop.

Maximum load, distributed over the roof
bars, for a loading height not exceeding
40 cm: 80 kg.
As this value may change, please
verify the maximum load quoted in the
instructions supplied with the roof bars.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the profile of the
road to avoid damaging the roof bars and
the fixings on the vehicle.
Be sure to refer to national legislation in
order to comply with the regulations for
transporting objects which are longer than
the vehicle.

When the bonnet is open, take care not to
damage the safety catch.
Do not open the bonnet under very windy
conditions.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades. Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid the risk of injury related to an
automatic change to START mode.

Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing, etc.) be limited.

The Diesel fuel system operates under
very high pressure.
All work on this circuit must be carried out
only by a CITROËN dealer or a qualified
workshop.
Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluid must comply with the
manufacturer's recommendations and with
the vehicle's engine. Take care when working under the bonnet,
as certain areas of the engine may be
extremely hot (risk of burns) and the
cooling fan could start at any time (even
with the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop and dispose of
it in the containers reser ved for this
purpose.
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick.
