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).

Warning and indicator
lamps
Displayed as symbols, the warning and indicator
lamps inform the driver of the occurrence of a
malfunction (warning lamps) or of the operating
status of a system (operation or deactivation
indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.
For more information on a system or a function,
refer to the corresponding section.
Warning lamp continuously
lit
The illumination of a red or orange warning lamp
indicates the occurrence of a fault that needs
further investigation.

Ease of use and comfort

This allows the storage of a toll ticket or a
parking card for example.
Mats
Fitting

When fitting the mat for the first time on the
driver's side, use only the fasteners supplied in
the enclosed sachet.
The other mats are simply laid over the carpet.
Removing/refitting
► To remove it on the driver's side, move the
seat backwards and unclip the fasteners.
► To refit it, position the mat and secure it by pressing.► Check that the mat is secured correctly .
To avoid any risk of jamming the pedals:– Only use mats which are suitable for the fasteners already present in the vehicle;
these fasteners must be used.
– Never fit one mat on top of another.The use of mats not approved by CITROËN
may interfere with access to the pedals and
hinder the operation of the cruise control/
speed limiter.
The approved mats have two fasteners
located underneath the seat.
Rear fittings
Seat backrest pockets
They are located in the backrests of the front
seats.
Side blinds
Fitted to the windows in the second row, they
protect the passenger compartment from the
sun's rays.


► Pull the tab A and anchor the blind on the
hook B.
Always guide the blind slowly using the tab, both up and down.
Clothes hooks

They are located above each rear door.
Rear armrest and ski flap
It has two cup holders (depending on version).
It gives direct access to the boot for transporting
long objects.

Driving
6the whole manoeuvre, in particular using the
mirrors.


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away from the sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
– Ensure that the mat is secured correctly .– Never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
in the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Head-up display
System which projects various information onto a
smoked blade in the driver's field of vision so that
they do not have to take their eyes off the road.

Information displayed
during operation


Once the system has been activated, the
following information is grouped together in the
head-up display:
A.The speed of your vehicle.
B. Cruise control/speed limiter information.
C. If your vehicle is suitably equipped, automatic
emergency braking alerts and navigation
instructions.
D. If your vehicle is suitably equipped, speed
limit information.

refer to the section Audio equipment
and telematics.
Selector


1. On.
2. Off (long press).
3. Brightness adjustment.
4. Display height adjustment.
Activation / Deactivation
► With the engine running, press button 1 to
activate the system and deploy the blade.


► Press and hold button 2 to deactivate the
system and retract the blade.
The activated/deactivated state is saved and
restored on restarting the engine.
Height adjustment
► With the engine running, adjust the display to the desired height using buttons 4:• up to move the display up,• down to move the display down.
Brightness adjustment
► With the engine running, adjust the brightness of the information display using button
3:
• the "sun" to increase the brightness,• the "moon" to decrease the brightness.
When stationary or while driving, no
objects should be placed around the
blade (or in its recess) so as to not impede
deployment of the blade and its correct
operation.
In certain extreme weather conditions (rain and/or snow, bright sunshine, etc.)
the head-up display may not be legible or
may suffer temporary interference.
Some sunglasses may hamper reading of the
information.
To clean the blade, use a clean, soft cloth
(such as a spectacles cloth or microfibre
cloth). Do not use a dry or abrasive cloth
or detergent or solvent products as these
could scratch the blade or damage the anti-
reflection coating.
This system operates when the engine is running, and the settings are saved when
the ignition is switched off.
Memorising speeds
This function allows speeds to be saved, which
can then be offered to set the two systems: the
speed limiter (to limit the speed of the vehicle) or
the cruise control (for a vehicle cruising speed).
You can memorise up to six speed settings for
each of the two systems.
By default, some speed settings are already
memorised.
As a safety measure, the driver must only modify the speed settings when
stationary.
