AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the

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.

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.

Safety
5Normal 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.
Anti-slip regulation (ASR) / Dynamic stability control
(DSC)
Anti-slip regulation (or traction control) optimises
traction by using engine braking and by applying
the brakes on the driving wheels to avoid one
or more wheels spinning. It also enhances the
vehicle's directional stability.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by the flashing of this warning lamp on the instrument panel.
Deactivation/Reactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
these systems, so that the wheels can turn freely
and regain grip.
Reactivate the systems as soon as the level of
grip permits.
This function is set via theDriving/Vehicle touch screen menu.
► Or, depending on version, turn the
"Grip control " knob to this position.
Deactivation is confirmed by the lighting
of this indicator lamp on the instrument
panel and the display of a message.
These systems are reactivated automatically
every time the ignition is switched off, or at
speeds over 31 mph (50
km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a system malfunction, this
warning lamp comes on, accompanied by
an onscreen message and audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the systems checked.
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 used by CITROËN dealers.

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.

Safety
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
Operation
Switching on
By default, the system is not selected.
The state of the function is not saved when the
ignition is switched off.
The driver can select the system when the

When the vehicle begins its descent, you can
release the accelerator and brake pedals; the
system regulates the speed:
– if the gearbox is in first or second gear ,
the speed decreases and the
indicator
lamp flashes rapidly,
–

if the gearbox is in neutral or if the clutch pedal
is depressed, the speed decreases and the
indicator

lamp flashes slowly; in this case, the
maintained descent speed is lower.
On a descent, with the vehicle stationary, if you
release the accelerator and brake pedals, the
system will release the brakes to set the vehicle
gradually in motion.
The brake lamps light up automatically when the
system is regulating.
If the speed exceeds 19 mph (30
km/h),
regulation is paused automatically, the
indicator
lamp goes back to grey in the
instrument panel, but the green indicator lamp in
the button remains on.

displayed in the instrument panel.
Have it checked by a CITROËN dealer or a
qualified workshop.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
