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:

Access
2To avoid the risk of injury through pinching or trapping, before and during
operation of the motorised tailgate:
–

ensure that there is no-one close to the
rear of the vehicle.
–


monitor the activity of the rear passengers,
particularly any children.
Bicycle carrier/Towing device
The motorised tailgate is not designed to support
a bicycle carrier.
When installing a bicycle carrier on the towing
device with connection of the cable to the trailer
socket, the motorised operation of the tailgate
will be automatically deactivated.
If using a towing device or bicycle carrier
not recommended by CITROËN, it is
essential to deactivate the motorised
operation of the tailgate.
Motorised operation
The motorised operation of the tailgate is configured in the Settings
> Vehicle
touch screen application.


There are several ways of operating the tailgate:
A. Using the Keyless Entry and Starting
system’s electronic key
B. Using the exterior tailgate control
C. Using the interior tailgate control
D. Using the control on the dashboard
Opening
► A long press on the central button A of the
electronic key.
or
►

A
short press on the exterior tailgate control
B, with the electronic key on your person.
or
►

T
wo consecutive presses on the control D on
the dashboard.
The tailgate opens, either completely by default, or to the position memorised
beforehand.
If motorised operation is not activated, these
actions release the tailgate (partially-open
position).
When the vehicle is locked, the request to
open the boot with one of the controls A
or B unlocks the vehicle, or only the boot if
selective unlocking is activated, prior to the
opening of the boot.
Closing
► A short press on the interior tailgate control C.
It is possible to interrupt the operation of
the tailgate at any point.
Pressing one of these controls again
interrupts the movement that is underway.
Memorising an opening
position
To limit the opening angle of the motorised
tailgate:
►

move the tailgate to the desired position
manually or by pressing the button.
►


press button
C or the exterior control B for
more than 3 seconds (memorisation is confirmed
by a brief audible signal).
A new memorisation operation cancels the
previous one.

35
Access
2

► Position yourself behind the vehicle by the
number plate and perform a “kicking” movement
in the “
OK” detection zone.
The “kicking” movement must be given forwards,
smoothly, not too fast and with a vertical
movement from low to high. Raise the foot
sufficiently and remove it immediately.
The taking into account of the “kicking”
movement is confirmed by the lighting of the
direction indicators.
"Sideward kicking" movements do not
work. If the “kicking” movement has not
been detected, wait at least 2 seconds before
repeating the movement.
Do not perform repetitive “kicking”
movements.
If the motorised tailgate has not started to open,
check that:
–

the function is activated.
–


the electronic key is on your person, outside
the vehicle in the rear recognition area.
–


the “kicking” movement was performed in the
detection zone, close enough to the bumper

.
–

the foot was removed from the bumper quickly
enough.
When the vehicle is locked, the request
to open the tailagte with this function
unlocks the vehicle, or only the tailgate if
selective unlocking is activated, prior to the
opening of the tailgate.
Closing the tailgate with the “Hands-Free
Tailgate Access” function enables you to lock
the vehicle.
Recommendations on the
hands-free function (Hands-
Free Tailgate Access)
If it does not work, check that the electronic key
is not exposed to a source of electromagnetic
interference (e.g. smartphone).
The function may be deactivated or affected if
there is rain or snow.
The function may not work correctly with a
prosthetic leg.
In some circumstances, the tailgate may open or
close by itself, particularly when:
–

hitching up or removing a trailer;
–


fitting or removing a bicycle carrier;
–


loading
or unloading bicycles on/from a bicycle
carrier;
–

depositing or lifting something behind the
vehicle;
–


an animal approaches the rear bumper;
–


washing the vehicle;
–


maintenance is performed on the vehicle;
–


accessing the spare wheel.
T

o avoid such operating problems, keep the
electronic key away from the recognition zone or
deactivate the hands-free function.
The installation of a towing device may disturb the detection system.
To avoid unintentionally opening the tailgate
while operating the towing device:
►

remove the electronic key from the
recognition zone, with the tailgate closed.
For more information on the T

owing device
with quickly detachable towball , refer to the
corresponding section.
Alarm
(Depending on version)

74
Safety
Deactivation/reactivation is confirmed by
the lighting/switching off of this indicator
lamp on the instrument panel and the display of
a message.
The ASR system is reactivated automatically
every time the ignition is switched on or at
speeds over 31 mph (50
km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures provided by CITROËN
dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow
or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings , refer to the
corresponding section.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer snaking.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC)
must not have any faults.
The vehicle speed must be between 37 and 99
mph (60 and 160
km/h).
If the system detects that the trailer is
snaking, it applies the brakes to stabilise
the trailer and reduces engine power, if
necessary, to slow the vehicle (indicated by the
flashing of this warning lamp on the instrument
panel and the brake lamps coming on).
For information on weights and towed loads,
refer to the Engine technical data and towed
loads section or your vehicle’s registration
certificate.
To ensure safe driving with a Towing device,
refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp lights
up on the instrument panel, accompanied
by a message and an audible signal.
To continue towing a trailer, reduce speed and
drive carefully!
Have it checked by a CITROËN dealer or a
qualified workshop.
The trailer stability control system provides an extra safety feature under
normal driving conditions, when following the
recommendations for use of trailers and
current legislation in force in your country. It
must not encourage the driver to take extra
risks, such as using a trailer in unsuitable
conditions of operation (e.g.
excessive load,
exceeded nose weight, worn or under-inflated
tyres, faulty braking system) or driving at
excessive speed.
In certain cases, the system may not detect
trailer snaking, particularly with a light trailer.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
trailer snaking.

89
Driving
6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a CITROËN dealer.
Starting/Switching off the
engine with Keyless Entry
and Starting
The electronic key must be present in the passenger compartment.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off.

displayed (orange) instead of the speed setting.
This warning lamp comes on, accompanied by a message and an
audible signal, to confirm the malfunction.
Have it checked by a CITROËN dealer or a
qualified workshop.
Lane positioning assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


The system identifies the limits of the traffic
lane and steers the vehicle inside this lane to
maintain it in the lateral position chosen by the
driver.
To do this, the system uses a camera placed on
the upper part of the windscreen.
This function is primarily suitable for driving on
motorways and main roads.
Activation/Deactivation
Lane positioning assist is automatically activated,
after selecting
Highway Driver Assist mode.
For more information on Highway Driver Assist,
refer to the corresponding section.
The selection is confirmed by the display of the
symbols on the instrument panel, representing
the steering wheel and the side lines.
The colour of the symbols depends on the
operating state of the system:
(grey)
One or more operating conditions is not met; the
system is paused.
(green)
All operating conditions are met; the
system is active.
(orange)
System malfunction.
If the driver no longer wishes to use the system
for some time, they can deactivate it by pressing
the ASSIST button again (confirmed by the
disappearance of the Driving aids mini-view on
the instrument panel).
The system status is saved when the ignition is switched off.

For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and the
Cruise control - particular
recommendations.
In addition to Adaptive Cruise Control with
Stop&Go and Lane positioning assist systems,
this system regulates the speed of the vehicle in
bends.
It adapts the speed, with or without target
vehicle, in certain bends on motorways or main
roads.
The speed is only adjusted if the vehicle speed is
not compatible with the angle of the bend.
The reduction in speed on a bend is adapted
to the situation in order to ensure the bend is
navigated comfortably.
In the presence of a target vehicle, it also
maintains the inter-vehicle distance.
This system does not manage bends that are too tight ("hairpin bend" for example).

Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This system:
–
warns the driver that their vehicle is at risk of
collision with the preceding vehicle, a pedestrian
or a cyclist.
–

reduces the vehicle's speed to avoid a
collision or to limit its severity

.
The speed will be reduced by a maximum of 16 mph (25 km/h) (versions
with camera only) or by a maximum of 31
mph (50 km/h) (versions with camera and
radar).
The system also takes motorcyclists into account. It may also react on animals.
Animals (especially animals smaller than
0.5

m) and objects on the road are not
necessarily detected.
This system includes three functions:
– Collision Risk Alert.
–

Intelligent emergency braking assistance
(iEBA).
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not replace the need for driver vigilance.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor traffic conditions in accordance with
applicable driving regulations.
As soon as the system detects a potential collision, it prepares the braking
circuit. This may cause a slight noise and a
slight sensation of deceleration.

125
Driving
6Deactivation/Activation
By default, the system is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits
Vehicle moving forward without trailer.
Brake system operational.
ASR / ESP system activated.
Seat belts fastened for all passengers.
Stabilised speed on roads with no or low
curvature.
This warning lamp lights up on the instrument panel without any additional
message, to indicate that the “automatic braking
system” is not available. This is a normal
behavior indicating that a condition is not fulfilled
and which does not request the support of a
workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the
system via ADAS touch screen application is
recommended, for instance:
–

T

owing a trailer (particularly a trailer without its
own braking system).
–

Carrying long objects on roof bars.
–


Driving with snow chains.
– Using an automatic car wash.
– Performing any maintenance (e.g. changing a
wheel, working underhood).
–

Placing the vehicle on a rolling bench in a
workshop.
–


T
owing the vehicle.
–

Following a front bumper deformation (version
with radar).
–


Following
an impact to the windscreen close to
the detection camera.
The system is automatically deactivated if:
–

A

spare wheel with a too small diameter is
detected.
–

A

fault with the brake pedal switch or with
the right or left brake lamp is detected.
–

A

fault in the sensors, in the electronic or in
the brake system is detected.
–

A

trailer is detected by the equipped vehicle
hitch (with an electrical connection plug).
The system diagnoses permanently its capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions.
Examples: sensor initialization, board voltage
out of regular range, activation of stability
system…
Therefore the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not load his vehicle excessively (respect of MTAC values,
MTRA values and loading height on roof
bars).
Following an impact (e.g. a collision), the
system is automatically deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.
►

Select one of the 3 preset thresholds: “ Far

”,
“Medium” or “Near”.
The selected threshold is memorised when the
ignition is switched off.
