Operating fault
In the event of a fault with the cruise
control, you are alerted by the
illumination of this warning lamp
and the display of a message in the
instrument panel, accompanied by an
audible signal.
The cruise control operates by day and at night, in fog or moderate rainfall.
However, it is strongly recommended that you always keep a safe distance from vehicles
ahead, depending on the driving conditions, the weather and the road sur face.
Use the cruise control only where the driving conditions allow running at a constant speed
and at an adequate safe distance.
Do not use the cruise control in urban areas, heavy traffic, on winding or steep roads, on
slippery or flooded sur faces, in snow, if the front bumper is damaged or if the brake lamps
are faulty.
In certain circumstances, it may not be possible for the speed setting to be maintained or
even attained: loaded vehicle, ascending a steep hill, etc.
The system is not intended for the following situations:
-

t

he front end of the vehicle has been modified (addition of driving lamps, paint on the
bumper),
-

d

riving on a racing circuit,
-

r

unning on a rolling road,
-

u

se of snow chains, non-slip covers or studded tyres. Have the system checked by a CITROËN
dealer or a qualified workshop.
The operation of the radar, located in the front bumper, may be disturbed by accumulations
of dirt (dust, mud, etc.) or in certain weather conditions (snow, ice, etc.).
The message "SYSTEM INACTIVE: Visibility reduced" is displayed to signal that the system
has been put into standby.
Clean the front bumper regularly.
When painting or touching up the paint on the front bumper, consult a CITROËN dealer or a
qualified workshop. Certain types of paint could hinder the operation of the radar. The use of mats not approved by CITROËN may inter fere with the operation of the cruise
control.
To avoid any risk of jamming the pedals:
-

e

nsure that mats are secured correctly,
-

n

ever fit one mat on top of another.

Collision Risk Alert and Active Safety Brake
This system includes three functions:
- C ollision Risk Alert (alert if there is a risk of
collision),
-

I
ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
Collision Risk Aler t: 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 completes the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it inter venes following
the aler t if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, the system
contributes towards avoiding a collision or
limiting its severity by reducing the speed
of your vehicle. This system is designed to assist the
driver and improve road safety.
It is the driver's responsibility to
continuously monitor the state of
the traffic, observing the driving
regulations.
This system does not avoid the need for
vigilance on the part of the driver.
The vehicle is fitted with a radar located in the front bumper and a camera at the top of the
windscreen.
Conditions for activation and operation
The system is active from about 4 mph (7 km/h)
and is deactivated below about 3 mph (5 km/h).
It takes account of:
-

v
ehicles running in the same direction or
stationary,
-

p
edestrians present in the traffic lane
(bicycles, motorcycles, animals and objects
on the road are not necessarily detected).

176
Limits of operation
In the following cases, it is recommended
that the system be deactivated in the vehicle
configuration menu:
-
w
hen towing a trailer or caravan,
-

w
hen carrying long objects on roof bars or
a roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling road
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-

f
ollowing impact damage to the windscreen
close to the detection camera,
-

i
f the front bumper has been damaged,
-

i
f the brake lamps are not working.Because of limits in the operation of the
system, it is possible that warnings are
not given, are given too late or seem
unjustified.
Consequently, the driver must always
remain attentive and able to react at any
time to avoid an accident. 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
di r e c t l y.
Important:
the level 1 alert is never
displayed if the " Close" threshold has
been selected.
Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of alert can be
triggered and displayed in the instrument panel.
Level 1: visual alert only, signalling
to you that the vehicle in front is very
close.
The message " Vehicle close" is
displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front.
Level 2: visual and audible alert,
warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment.
Modifying the alert trigger
threshold
This threshold determines how you wish to be
warned of the presence of a vehicle moving
or stationary in front of you, or a pedestrian
present in your traffic lane.
The current threshold can be modified only via
the Driving menu in the touch screen.
You can select one of three thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Driving

177
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.
Using a radar and a camera, this function acts
on the vehicle's braking system.Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained
for
1 to 2 seconds.
With a manual gearbox, in the event
of the automatic emergency braking
bringing the vehicle to a complete stop,
the engine may stall.
With an automatic gearbox, in the event
of the automatic emergency braking
bringing the vehicle to a complete stop,
keep the brake pedal pressed to stop
the vehicle moving off again.
If the radar and the camera have
confirmed the presence of a vehicle
or a pedestrian, this warning lamp
flashes once the function is acting on
the vehicle's brakes.
Important
: if operation of the
automatic emergency braking is
triggered, you should take back
control of your vehicle and brake
with the pedal to add to or finish the
automatic braking action.
The driver can take back control of the vehicle
at any time by sharply turning the steering
wheel and/or pressing the accelerator pedal.
The triggering of the braking may be
adjusted according to the driver's
driving actions (such as steering wheel
movements, actions on the accelerator
pedal, etc.).

Special features of the function
The speed of the vehicle must be between
3 mph (5 km/h) and 87 mph (140 km/h) when a
moving vehicle is detected.
The speed of the vehicle must not be higher
than 50 mph (80 km/h) when a stationary
vehicle is detected.
The speed of the vehicle must not be higher
than 37 mph (60 km/h) when a pedestrian is
detected.
The ESC system must not be faulty.
The ASR function must not be deactivated.
The seat belts of all occupants must be
fastened.
Driving at a steady speed on fairly straight
roads is required.
Following an impact, the function is put
out of service automatically, consult
a CITROËN dealer or a qualified
workshop to have the system checked.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to
avoid a collision, this system will complete the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
Deactivation / Activation
By default, the system is automatically
activated at every engine start.
The system can be deactivated or activated in
the vehicle settings menu in the screen. Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a message.
