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 a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
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.
Favour the use of “Eco” driving mode.
With an EAT8 gearbox, with the gear selector
in mode
D, and except in Sport mode, favour
"free-wheeling" by fully lifting your foot from the
accelerator pedal in order to save fuel. 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.
Avoid using Sport mode for too long, in order to
limit your energy consumption.
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.
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 legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.

Access
► press button C or the exterior control B for
more than 3 seconds (deletion is confirmed by a
long audible signal).
Manual operation
The tailgate can be manoeuvred by hand, even
with motorised operation activated.
The tailgate must be stationary.
When opening and closing the motorised tailgate
manually, there is no assistance from gas struts.
Resistance to opening and closing is therefore
entirely normal.
Repeatedly opening and closing the
motorised tailgate can cause overheating
of its electric motor, after which opening and
closing will not be possible.
Allow at least 10 minutes for the electric
motor to cool down before operating the
tailgate again.
If you are unable to wait, operate it manually.
Manual closing of the
motorised tailgate in case of
failure
This operation is only necessary in the case of
failure of the tailgate motor .
If the failure originates from the battery, it is
recommended to recharge it or change it with the
tailgate closed.
In this situation, a significant force may be
needed to close the tailgate.

► 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 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.
Automatic locking with the hands-free
function
The automatic locking of the vehicle with
the hands-free function can be activated/
deactivated via the Driving/V
ehicle touch
screen menu.
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.
Memorising an opening
position
To memorise a position, in order to limit the
motorised tailgate opening angle:
►

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).
Memorising is not available until the
height of opening is more than or equal
to 1 metre between the low position and the
high position of the tailgate.
To delete the memorised position:
►

open the tailgate to any position.

78
Safety
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems checked by a CITROËN dealer or a
qualified workshop.
Intelligent traction control
("Snow motion")
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control.
This system detects situations of poor surface
grip that could make it difficult to move off
or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control for
your vehicle.
The use of snow tyres is strongly recommended on surfaces offering low
levels of grip.
For technical reasons, in particular to
improve the quality of telematic services
for customers, the Manufacturer reserves the
right to carry out updates to the vehicle's
on-board telematic system at any time.
If you benefit from the Citroën Connect
Box offer with the SOS and Assistance
Pack included, there are additional services
available to you in your personal space, via
the website for your country.
For information about the SOS and
Assistance Pack, please refer to the general
conditions for these services.
Electronic stability control
(ESC)
Electronic stability control programme
comprising the following systems:
–

Anti-lock Braking System (ABS) and Electronic
Brake Force Distribution (EBFD).
–


Emergency braking assistance (EBA).
–


Anti-slip regulation (ASR).
–


Dynamic stability control (DSC).
–


T
railer stability assist (TSA).
Definitions
Anti-lock braking system (ABS) and electronic brake force distribution
(EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards improved control in
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance (EBA)
In an emergency, this system enables you
to reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by a
reduction in the resistance of the pedal and an
increase in braking efficiency.
Anti-slip regulation (ASR)
This system optimises traction in order to avoid
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves the
directional stability of the vehicle on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by the
driver, this system monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Trailer stability assist (TSA)
This system allows control of the vehicle to be
retained when towing a trailer, so as to avoid the
risk of snaking.
Anti-lock braking system (ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning lamp
signals that there is a fault with the ABS.
The vehicle retains conventional braking. Drive
carefully at moderate speed.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
Illumination of this warning lamp, coupled
with the STOP and ABS warning lamps,
accompanied by the display of a message and
an audible signal, signals that there is a fault with
the electronic brake force distribution (EBFD).
You must stop as soon as it is safe to do so.
Call a CITROËN dealer or a qualified workshop.

80
Safety
Standard (ESC)
This mode is calibrated for a low level of wheel spin, based on the different levels
of grip normally encountered on the road.
Whenever the ignition is switched off, the
system automatically resets to this mode.
Snow
This mode adapts its strategy to the conditions of grip encountered for each of
the two front wheels on moving off.
(mode active up to 50 mph (80 km/h))
All terrain (mud, damp grass, etc.)
This mode, when moving off, allows considerable spin on the wheel with the
least grip to optimise clearing of the mud and to
regain grip. At the same time, the wheel with the
most grip is controlled in such a way as to
transmit as much torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully
as possible.
(mode active up to 31 mph (50 km/h))
Sand
This mode allows little spin on the two driving wheels at the same time to allow
the vehicle to move forward and limit the risks of
getting stuck in the sand.
(mode active up to 75 mph (120 km/h))
The use of snow tyres is recommended, to
ensure that these systems remain effective
in winter conditions. All four wheels must be
fitted with tyres approved for the vehicle.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control (ESC) must not
have any faults.
If the system detects oscillations (snaking) in the
movement of the trailer at speeds between 35
and 100 mph (60 and 160 km/h), it acts on the
brakes to stabilise the trailer and, if necessary,
reduces the engine power to slow down the
vehicle.
The correction is signalled by the flashing of this indicator lamp in the instrument
panel and illumination of the brake lamps.
For information on the weights and towed loads,
refer to the "Technical data" section or the
registration certificate for your vehicle.
To ensure complete safety while driving with
a Towbar system, refer to the corresponding
section.
Operating fault
Should a fault occur with the system, this
warning lamp comes on in the instrument
panel, accompanied by the display of a message
and an audible signal.
If you continue to tow a trailer, reduce your
speed and drive carefully!
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The trailer stability assist system offers increased safety in normal driving,
provided that the recommendations on towing
a trailer are observed. It should not
encourage the driver to take risks, such as
towing a trailer in adverse operating
conditions (overloading, failure to observe the
trailer nose weight, worn or under-inflated
tyres, faulty braking system, etc.) or drive at
too high a speed.
In certain cases, snaking of the trailer may not
be detected by the ESC system, particularly
with a light trailer.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
snaking of the trailer.
Advanced Grip Control
(Depending on version)
A special, patented traction control system,
which improves driveability on snow, mud and
sand. This system, optimised for operation in a range
of conditions, enables you to manoeuvre in most
slippery conditions (encountered during normal
passenger car use).
This system, which can be combined with all-
season M+S (Mud and Snow) tyres, offers a
compromise between safety, grip and driveability.
The accelerator pedal should be pressed
sufficiently to allow the system to harness the
power of the engine. Operation at high engine
speeds is completely normal.
A five-position selector knob allows you to
choose the setting best suited to the driving
conditions encountered.
An indicator lamp associated with each mode
comes on, accompanied by the display of a
message to confirm your choice.

Driving
6Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►

Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
►


Drive smoothly
, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
►

Stop the vehicle to carry out operations that
require close attention (such as adjustments).
►


During long trips, take a break every two
hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), let the engine
run for 4 minutes before moving off, to ensure
the correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damaging the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (e.g. dry grass, dead leaves).The
vehicle exhaust system is very hot, even
several minutes after the engine stops. Risk
of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the internal combustion engine or electric motor,
the gearbox and the electrical systems of the
vehicle.


If you are obliged to drive on a flooded road:
► Check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users.
►

Deactivate the Stop & Start function.
►


Drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10

km/h).
►

Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow

, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
Towing
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).

98
Driving
automatically to preserve the remaining battery
charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
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.
In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, which secret code must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact the CITROËN dealer.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:
– position 1 (Stop): inserting and removing the
key, steering column locked.
–
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating, engine
running,
–
position 3 (Starting).
Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch and
could cause a malfunction.
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops to
the reserve level, the system switches to energy
economy mode : the power supply is cut off
