Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
Optimise your use of the gearbox
With an automatic gearbox, favour automatic
mode. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift 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 practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of electrical equipment
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 (e.g.
sunroof blind, window blinds).
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.
Adapt the use of headlamps and/or foglamps
depending on visibility conditions.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving.
As a passenger, avoid connecting your
multimedia devices (e.g. film, music, video
game) to help reduce the consumption of energy.
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 (e.g.
roof bars, roof
rack, bicycle carrier, trailer). 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 the 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 forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, 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).
Optimising the driving range
(rechargeable hybrid vehicles)
Connect the vehicle as soon as possible.
Favour the ECO zone of the power indicator by
driving smoothly and at a steady speed.
Anticipate slowing down as much as possible
and, if possible, favour decelerations with
regenerative braking mode activated (power
indicator in the CHARGE zone).
With the vehicle connected, carry out
temperature pre-conditioning before setting off.
To optimise consumption during a journey:

3Mats
Fitting

When fitting it on the driver's side, only use
the mountings present on the carpet (a "click"
indicates proper locking).
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.
►
T
o refit it, position the mat and secure it by
pressing down.
►

Check that the mat is secured correctly
.
To avoid any risk of jamming the pedals:– Only use mats which are suited to the
fixings already present in the vehicle; these
fixings 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.
Courtesy lamps
1. Front courtesy and reading lamps
2.Rear reading lamps
Front courtesy lamp
It comes on gradually:
–
when the vehicle is unlocked.
–

when the ignition is switched off.
–


when a door is opened.
–


when the remote control locking button is
activated, in order to locate the vehicle.
It switches off:
– when the vehicle is locked.
–

when the ignition is switched on.
–


30 seconds after the last door is closed.
The front and rear reading lamps come on and
go off at the same time as the courtesy lamp.
Reading lamps
► With the ignition on, operate the
corresponding switch.
Take care not to place anything in contact with the courtesy lamps.
Interior ambient lighting
The interior ambient lighting casts soft lighting,
both day and night.
Interior ambient lighting is associated with
display lighting depending on the driving mode
selected.
You can activate/deactivate this function and adjust the brightness in the
Settings
> Brightness touch screen application.

Driving
For versions fitted with Proximity Keyless
Entry and Start, the electronic key is also
detected in the boot.
If there is still a problem, refer to the "Key
not detected - Back-up starting or Back-up
switch-off" section.
Starting
► Select mode P or N on the automatic
gearbox, then depress the brake pedal.


► Press the " START/STOP" button while
maintaining pressure on the pedal until the
engine starts.
In all circumstances, if one of the starting
conditions is not met, a message is displayed.
In some circumstances, a message indicates
that it is necessary to turn the steering wheel
while pressing the " START/STOP" button to
assist unlocking of the steering column.
Petrol engines
With Petrol engines, after a cold start,
pre-heating the catalytic converter can cause
noticeable engine vibrations, for anything up
to 2 minutes (accelerated idle speed).
Starting rechargeable hybrid
vehicles
► Fully depress the brake pedal and press
the START/STOP button for approximately 2
seconds.
► Keep you r foot on the pedal until this
indicator lamp comes on, indicating the
activation of the rechargeable hybrid system
(confirmed by an audible signal).
To exit Park mode, wait for the READY indicator lamp to come on.
By default, the system starts in Electric mode.
Depending on certain parameters (battery
charge level or outside temperature), the system
determines whether it is necessary to start the
petrol engine.
It is possible to change the driving mode at any
time using the mode selector.
When the vehicle starts in electric mode,
it makes no noise.
Pay particular attention to pedestrians and
cyclists who may not hear the vehicle coming
despite the pedestrian horn.

P on the automatic gearbox.
► Press the "START/STOP" button.
► For rechargeable hybrid vehicles, before
leaving the vehicle, check that the READY

indicator lamp is switched off.
The automatic gearbox locks in mode P.
If the vehicle is not immobilised, the
engine will not stop.
With the engine off, the braking and
steering assistance systems are also cut
off - risk of loss of control of the vehicle!
Never leave your vehicle with the
electronic key still inside.
Switching on the ignition
without starting the engine
With the electronic key in the passenger
compartment, pressing the " START/STOP"
button, without depressing any of the pedals ,
allows the ignition to be switched on without

6Maintenance
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 radar, sensors and cameras.
Mats / Pedals covers
The use of mats or pedals covers not
approved by CITROËN may interfere with
the operation of the speed limiter or cruise
control.
T
o 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.
Steering wheel with
hands-on detection
(with Highway Driver Assist 2.0)
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The steering wheel is equipped with a hands-on
detection system to avoid distraction on the part
of the driver.
It is prohibited to cover or attach anything to the
steering wheel.
The driver must always check the surroundings of the vehicle and
supervise the whole manoeuvre.
Any use of a system built into
Highway Driver
Assist 2.0
must remain under the driver’s
vigilance.
The system also detects the presence of
hands when using the Lane Positioning assist
system with Highway Driver Assist.
The system may suffer interference or not work correctly if:
–

the steering wheel is covered by some
protection.
–


the driver wears thick gloves (e.g.
ski
gloves).
In the event of improper detection of hands on
the steering wheel, Highway Driver Assist 2.0
is not activated or is deactivated after a few
seconds.
Installation of mechanical anti-theft
devices on the steering wheel is
prohibited - risk of damage!
Shortcuts for driving aids
Driving aids can be accessed directly to quickly
activate/deactivate them.
By default, driving aids are already stored in the
system (e.g. Stop & Start,

Active lane departure
warning system).
Other driving aids can be added or deleted from
the page.
It is configured in the ADAS>Functions
touch screen application.
► Press the button corresponding to the
driving assistance concerned:
•

Full symbol: the function is added to the
shortcuts.
•


Empty symbol: the function is deleted from
the shortcuts.
►


Check the modification in the Shortcuts

tab.

Driving
Operating limits
The system does not take account of reduced
speed limits, especially those imposed in the
following cases:
–
Atmospheric pollution.
–

Towing.
–

Driving with a space-saver type spare wheel
or snow chains fitted.
–


T
yre repaired using the temporary puncture
repair kit.
–

Y
oung drivers.
The system may not display the speed limit if it
does not detect a speed limit sign within a preset
period and in the following situations:
–

Road signs that are obstructed, non-standard,
damaged or bent.
–


Obsolete or incorrect maps.
Speed setting
recommendations
The driver can select the speed displayed by the
Road signs recognition function as the speed
setting for the speed limiter, cruise control or
adaptive cruise control using the

OK
button.
In the event of rain detection, the system offers
the driver a speed setting lower than the speed
read/from the map in order to adapt to weather
conditions (e.g.
on motorways, the proposed
speed is 68 mph (110 km/h) instead of 81 mph
(130 km/h).
Speed setting advance recommendations
With Highway Driver Assist 2.0 activated,
the system detects the next speed limit sign,
displays it in the background and proposes this
new speed as the speed setting.
Once memorised:
–

If the speed setting is lower than the previous
one, the vehicle slows down to reach this new
speed when it gets to the sign.
–


If the speed setting is higher than the previous
one, the vehicle speeds up to reach this new
speed when it passes the sign.
For more information on the Speed
limiter, Cruise control or Adaptive
cruise control, refer to the corresponding
sections.
