brand's dealer network, we invite you to
have a dealer check the configuration of
these ser vices and, if desired, modify it to
suit your wishes. In a multilingual country,
configuration is possible in the official
national language of your choice.
For technical reasons and, in particular, to
improve the quality of Telematic ser vices
to customers, the manufacturer reserves
the right to carry out updates to the
vehicle's on-board telematic system.
If you benefit from the Citroën Connect
Box offer with the SOS and assistance
pack included, there are additional
ser vices available to you in your personal
space, via the website for your country.Electronic stability control
(ESC)
Electronic stability control (ESC) comprising
the following systems:
-
a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-

e
mergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-

d
ynamic stability control (DSC).
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and
contributes towards improved control on corners,
in particular on poor or slippery road sur faces.
The ABS prevents wheel lock in the event of
emergency braking.
The EBFD 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.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
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, the DSC 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. 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 the effectiveness of the braking.

Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp indicates that there is a fault
with the ABS.
The vehicle retains conventional braking. Drive
carefully at moderate speed. If these warning lamps come on,
accompanied by an audible signal
and a message, this indicates a
fault with the electronic brake force
distribution (EBFD) system.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal. In emergency braking, press ver y
firmly and maintain this pressure.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
Anti-slip regulation (ASR)/
Dynamic stability control
(DSC)
Operation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of a
problem with grip or trajectory.
Deactivating the ASR (depending
on version)
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
You must stop as soon as it is safe to do so.
In both cases, have the system checked by a
CITROËN dealer or a qualified workshop as
soon as possible.
This is indicated by this warning
lamp flashing in the instrument
panel.It is however recommended that the system be
reactivated as soon as possible.

urn the "
Grip control" knob to
this position.
Deactivation is confirmed by the
illumination of this warning lamp,
accompanied by a message as
well as illumination of the knob
(depending on version).
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
Reactivating the ASR (depending
on version)
The system is reactivated automatically every
time the ignition is switched back on or from
30
mph (50 km/h).
Below 30
mph (50 km/h), you can reactivate it
manually:

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.F

P
lace the knob in this position.
Every time 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))
F

P
lace the knob in this position.
All road (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 30
mph (50 km/h))
F

P
lace the knob in this position.
Sand
This mode allows little spin on the two driving
wheels at the same time to allow the vehicle to
move for ward and limit the risks of getting stuck
in the sand.
(mode active up to 75 mph (120 km/h))
F

P
lace the knob in this position.
Do not use the other modes on sand as
the vehicle may become stuck. You can deactivate the ASR
system by turning the knob to
the "
OFF" position.
The ASR system no longer acts on the
operation of the engine or the brakes in the
event of an involuntary change of trajectory.
This system is reactivated automatically
from 30 mph (50 km/h) or every time the
ignition is switched on.
Driving recommendations
Your vehicle is designed principally to
drive on tarmac roads but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road
driving such as:
-

c
rossing and driving on terrain which
could damage the underbody or strip
away components (fuel pipe, fuel
cooler, etc.) due to obstacles or stones
in particular,
-

d
riving on terrain with steep gradients
and poor grip,
-

c
rossing a stream.
Safety

97
Hill Assist Descent
System that provides assistance when
descending on loose or soft sur faces (gravel,
mud, etc.) or a steep gradient.
This system reduces the risk of slip or loss
of control of the vehicle when descending,
whether going forward or in reverse.
During a descent, it assists the driver in
maintaining a constant speed, depending
on the gear engaged, while progressively
releasing the brakes.For the system to activate, the slope must
be greater than 5%.
The system can be used with the gearbox
in neutral.
Otherwise, engage a gear corresponding
to the speed to prevent the engine stalling.
With an automatic gearbox, the system
can be used with the selector at N , D or R.
When the system enters regulating
mode, the Active Safety Brake system is
automatically deactivated. The system is no longer available if the
speed of the vehicle is above 30 mph
(50 km/h).
Operation
Switching on
By default, the system is not selected.
The system's status is not saved when the
ignition is switched off.
The driver can select the system when the engine
is running, when the vehicle is stationary or moving
at speeds up to 30 mph (50 km/h)
.
F With the speed below 30 mph
(50 km/h), press this button
until its indicator lights up to
select the system; this indicator
lamp appears in green in the
instrument panel.
The system becomes active at a speed below
20 mph (30 km/h). F

W
hen the vehicle begins its descent, you
can release the accelerator and brake
pedals, the system regulates the speed:
During 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 20 mph (30 km/h),
regulation is paused automatically, the indicator
lamp goes back to grey in the instrument panel,
but the indicator lamp in the button remains lit.
Regulation resumes automatically when the
speed falls below 20 mph (30 km/h) again, and
the slope and pedal release conditions are met.
You can depress the accelerator or brake pedal
again at any time. -

i
f the gearbox is in first or
second gear, the speed
decreases and the indicator
lamp flashes rapidly,
-
i
f 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.

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle. If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2
minutes after the vehicle
comes to a stop, to facilitate its cooling.
F

I

f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible. New vehicle
Do not pull a trailer before having driven at
least 600
miles (1,000 kilometres).
For more information on Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
A few seconds after switching off the ignition,
this system locks the engine control system,
therefore preventing the engine from being
started in the event of a break-in.
If the system fails, as reported by a message,
the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons,
never leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with
you.

Automatic operation
F Select position D for automatic changing of
the six gears.
The gearbox then operates in auto-adaptive
mode, without any action needed from the
driver. It continuously selects the most suitable
gear according to the style of driving, the profile
of the road and the load in the vehicle.
For maximum acceleration without touching
the selector, press the accelerator pedal down
fully (kick down). The gearbox changes down
automatically or maintains the gear selected
until the maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide efficient engine
braking.

Switching off
F Turn thumbwheel 1 to position 0: the cruise control information disappears from the
screen.
Malfunction
Flashing dashes indicate a fault with the cruise
control system.
Have it checked by a CITROËN dealer or a
qualified workshop. Use the cruise control only where the
driving conditions allow driving at a
constant speed for a while and at an
adequate safe distance.
Do not activate the cruise control in urban
areas, in heavy traffic, on winding or steep
roads, on slippery or flooded roads, or in
conditions of poor visibility (heavy rain,
fog, falling snow etc.).
In some circumstances, it may not be
possible to maintain or reach the cruise
speed set: towing, vehicle heavily loaded,
steep climb.
The use of mats not approved by
CITROËN may inter fere with the operation
of the cruise control.
To avoid any risk of jamming of the pedals:
-

e
nsure that the mat is positioned
c o r r e c t l y,
-

d
o not fit one mat on top of another.
Collision Risk Alert and
Active Safety Brake
Activation and operating
conditions
This system is a driving aid that includes three
functions.
Collision Risk Alert: it warns the driver if their
vehicle is at risk of collision with the vehicle in
front or a pedestrian present in their traffic lane.
Intelligent emergency braking assistance :
it supplements the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it intervenes following
the alert if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, it contributes
towards avoiding a collision or limiting
its severity by reducing the speed of your
vehicle.
The vehicle has a camera located at the top of
the windscreen.
Driving

144
Where the speed of your vehicle is too
high approaching another vehicle, the first
level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is never
displayed when the " Close" trigger
threshold has been selected.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or a
pedestrian present in your traffic lane.
The current threshold can be modified via the
vehicle configuration menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Without audio system
With audio systemIntelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid
a collision, this system will supplement the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
Active Safety Brake
This function, also called automatic emergency
braking, aims to reduce the speed of impact or
avoid a frontal collision by your vehicle where
the driver fails to react.
