Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise their
fuel consumption and CO
2emissions.
Optimise your use of the gearbox
With a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
With an automatic gearbox, favour automatic
mode and avoid pressing the accelerator pedal
heavily or suddenly.
The gear efficiency indicator prompts you to
engage the most suitable gear: whenever this
indication is displayed on the instrument panel,
follow it straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These attitudes
help to save fuel, reduce CO
2 emissions and
decrease general traffic noise.
If the vehicle has the steering-mounted
"CRUISE" control, use cruise control at speeds
above 25 mph (40 km/h) when the traffic is flowing well.
Use electrical equipment wisely
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31 mph (50 km/h), close the windows and leave the air vents open.
Consider using equipment that can help keep
the temperature in the passenger compartment
down (sunroof blind and window blinds, etc.).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat as soon as possible.
Switch off the headlamps and foglamps when
the visibility conditions do not require their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving.
As a passenger, avoid connecting your
multimedia devices (film, music, video game,
etc.) to help reduce consumption of electrical
energy, and hence fuel.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the
heaviest items in the boot, as close as possible
to the rear seats.
Limit the loads carried in the vehicle and
minimise wind resistance (roof bars, roof rack, bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Comply with servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
– before a long journey
.– at each change of season.– after a long period out of use.Do not overlook the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (engine oil,
oil filter, air filter, passenger compartment filter,
etc.) and observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
is faulty, your vehicle will emit pollution. Visit
a CITROËN dealer or a qualified workshop
as soon as possible to restore your vehicle’s
nitrogen oxide emissions to regulatory
compliance.
When filling the fuel tank, do not continue after
the third nozzle cut-out, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).

tip of the high-pressure lance at least 30 centimetres from the seals.
Never leave the vehicle with the sunroof
open.
Operation
When opening the sunroof fully, the movable
glass moves to a partially open position, then
slides over the roof. All intermediate positions
are allowed.
Depending on the speed of the vehicle,
the partially open position may vary to
improve the acoustics.
Before operating the sunroof or blind
control buttons, ensure that no object or
person might prevent the movement.
Be particularly aware of children when
operating the sunroof or blind.
If something is trapped when operating the
sunroof or blind, you should reverse the
movement of the sunroof or blind by pressing
the control in question.
The driver must ensure that passengers use
the sunroof and blind correctly.
Anti-pinch system
If the sunroof or blind encounters an obstacle
when closing, the movement is automatically
reversed.
The indicator lamp in the button goes off.► Reactivate the full alarm system by locking the vehicle using the remote control or the
Keyless Entry and Starting system.
The indicator lamp in the button flashes once per
second again.
Triggering of the alarm
This is indicated by sounding of the siren and
flashing of the direction indicators for thirty
seconds.
The volumetric and anti-tilt monitoring functions
remain active until the tenth successive time the
alarm is triggered.
When the vehicle is unlocked using the remote
control or the Keyless Entry and Starting system,
rapid flashing of the indicator lamp in the button
informs you that the alarm was triggered during
your absence. When the ignition is switched on,
this flashing stops immediately.
Failure of the remote control
To deactivate the monitoring functions:
► unlock the vehicle using the key (integral to the remote control) in the driver's door lock,► Open the door; this sets off the alarm.► Upon switching on the ignition the alarm stops. The button indicator lamp goes off.
Locking the vehicle without
activating the alarm
► Lock or deadlock the vehicle using the key (integral to the remote control) in the driver's
door lock.
Operating fault
When the ignition is switched on, fixed
illumination of the indicator lamp in the button
indicates a fault with the system.
Have it checked by a CITROËN dealer or a
qualified workshop.
Panoramic sunroof
The panoramic sunroof consists of a movable
glass panel that slides over the roof and a blind
that can be opened independently. Opening the
sunroof automatically opens the blind.
► To operate the panoramic sunroof or the blind, use the buttons in the roof console.

A.Sunroof blind control
B. Sunroof control
The sunroof or blind can be operated when the
ignition is turned on (if the battery is charged
enough), with the engine running, in STOP mode
of Stop & Start, and up to 45 seconds after turning off the ignition or after locking the vehicle.
Precautions
Do not put your head or arms through the
sunroof when driving - risk of serious
injury!
Ensure that any luggage or accessories
carried on the roof bars does not
interfere with the movement of the sunroof.
Do not place heavy loads on the movable
glass panel of the sunroof.
If the sunroof is wet, following a shower
or washing the vehicle, wait until it is
completely dry before opening.
Do not operate the sunroof if it is covered by
snow or ice - risk of damage!
Use only plastic scrapers to remove snow or
ice from the sunroof.
Check the condition of the sunroof seals
regularly (presence of dust or deposits,
dead leaves, etc.).
If using a car wash, check that the roof is
correctly closed in advance and keep the

2tip of the high-pressure lance at least 30
centimetres from the seals.
Never leave the vehicle with the sunroof
open.
Operation
When opening the sunroof fully, the movable
glass moves to a partially open position, then
slides over the roof. All intermediate positions
are allowed.
Depending on the speed of the vehicle,
the partially open position may vary to
improve the acoustics.
Before operating the sunroof or blind
control buttons, ensure that no object or
person might prevent the movement.
Be particularly aware of children when
operating the sunroof or blind.
If something is trapped when operating the
sunroof or blind, you should reverse the
movement of the sunroof or blind by pressing
the control in question.
The driver must ensure that passengers use
the sunroof and blind correctly.
Anti-pinch system
If the sunroof or blind encounters an obstacle
when closing, the movement is automatically
reversed.
The roof anti-pinch system is designed to be effective at speeds of up to 75 mph (120 km/h).
Opening / Closing
► To open the sunroof or the blind, use the part
of the button located towards the rear.
► To close the sunroof or the blind, use the part
of the button located towards the front.
Operation of buttons
► Pressing a button beyond its point of resistance directly opens or closes the sunroof
fully.
► Pressing the button again stops the current movement.► When holding a button (without going beyond the point of resistance), the movement
of the sunroof or blind stops when this button is
released.
► When the sunroof is closed: pressing once without passing the point of resistance moves it
to a partially open position.
► When the sunroof is partially open: pressing once without passing the point of resistance
opens or closes it fully.
The roof and windows, then the blind,
can be closed by holding down the door
locking control. The operation stops as soon
as the locking control is released.
Closing of the blind is limited by the
position of the sunroof: the blind cannot
go further than the front of the mobile glass.
During simultaneous movements of the
sunroof and blind, the blind automatically
stops or resumes movement depending on
the position of the sunroof.
Reinitialisation
Following reconnection of the battery or in the
event of a fault or jerky movement of the sunroof
or blind, reinitialisation is required.
► Check that nothing is interfering with the sunroof or blind and that the seals are clean.► With the ignition on, fully close the sunroof and blind.► Press and hold the front part of button B, until
the sunroof and blind move slightly, then hold for
a further 1 second before releasing.
► Wait 2 seconds and then press and hold the front part of button B. The blind and the sunroof
will open and close, one after the other. When
both are completely closed again, hold for a
further 2 seconds and release.
If there is an operating fault, restart the
whole procedure.

Lighting and visibility
4• If the "AUTO" and "Main beam" indicator lamps were on, the system changes to dipped beam.
To reactivate the system, flash the headlamps
again.
The system may be disrupted or not work correctly:
– When visibility conditions are poor (snowfall, heavy rain, etc.).– If the windscreen in front of the camera is dirty, misted or obscured (for example, by a
sticker).
– If the vehicle is facing highly reflective signs.
When the system detects thick fog, it
temporarily deactivates the function.
The system is not able to detect:
– Road users that do not have their own lighting, such as pedestrians.– Vehicles whose lighting is obscured (for example, vehicles driving behind a safety
barrier on a motorway).
– Vehicles at the top or bottom of a steep slope, on winding roads, on crossroads.
Clean the windscreen regularly,
particularly the area in front of the
camera.
The internal surface 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
obstruct the detection camera.
Headlamp beam height
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. (Initial adjustment)
Driver only or driver + front passenger
1. Driver + front passenger + rear passengers +
maximum authorised load
2. Driver only + maximum authorised load
Cornering lighting

If your vehicle is so equipped, 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, intersections, parking manoeuvres,
etc.).
