133
Driving
6Operating limits
The Lane Keeping Assist system may issue an alert when the vehicle is
travelling in a long straight lane on a smooth
road surface even if the driver is holding the
steering wheel properly.
The system may fail to operate or may produce
unsuitable corrections to the steering in the
following situations:
–

Poor visibility (insufficient road lighting,
snowfall, rain, fog).
–


Dazzle (headlamps of an oncoming vehicle,
low sun, reflections on a wet road surface,
leaving a tunnel, alternating light and shade).
–


Windscreen area in front of the camera being
dirty

, misted up, frost-covered, snow-covered,
damaged or masked by a sticker.
–

Lane markings eroded, partially hidden (snow
,
mud) or multiple (roadworks, surface joints).
–

T

ravelling in a tight bend.
–

Winding roads.
–


Presence of a tarmac joint on the road.
The system must not be activated in the following situations:
–

Driving with a "space-saver" type spare
wheel.
–


When towing, especially with an
unconnected or unapproved trailer

.
–

Poor weather conditions.
–


Driving on slippery road surfaces (risk of
aquaplaning, snow

, ice).
– Driving on racing circuits.
– Driving on a rolling road.
Malfunction
In the event of a malfunction, the
Service warning lamp comes on
and this (orange) symbol appears 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.
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
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 vehicle in front, a pedestrian or
,
depending on version, a cyclist.
–

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

.
The system also takes motorcyclists and animals into account; however, animals
below 0.5
m tall and objects on the road are
not necessarily detected.
This system is comprised of three functions:
–

Collision
Risk Alert.
–

Intelligent emergency braking assistance.
–


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 vigilance on the part of the driver.
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.

Driving
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or
when the "Near" trigger threshold has been
selected.
Intelligent 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 the driver
presses the brake pedal.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.
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.
ESC system in working order.
DSC/ASR systems activated.
Seat belts fastened for all passengers.
Stabilised speed on roads with few bends.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
–

T
owing a trailer.
–

Carrying long objects on roof bars.
–


V
ehicle with snow chains fitted.
–

Before using an automatic car wash, with the
engine running.
–


Before placing the vehicle on a rolling road in
a workshop.
–


T
owed vehicle, engine running.
– Damaged front bumper (version with radar).
– Following an impact to the windscreen close to
the detection camera.
The system is automatically deactivated when the use of certain types of
"space-saver" spare wheel (smaller diameter)
is detected, or if a fault with the brake pedal
switch or at least two brake lamps is detected.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
Collision Risk Alert
This function warns the driver that their vehicle
is at risk of a collision with the vehicle in front, or
with a pedestrian or cyclist present in their traffic
lane.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the Driving /
Vehicle touch screen menu.
►

Select one of the three pre-defined
thresholds: "Far", "Normal" or "Close".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
the instrument panel.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
steering wheel, etc.) to trigger the alert at the
most relevant moment.
Level 1 (orange): visual alert only,
warning that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
warning that a collision is imminent.
The message "Brake! " is displayed.
Where the speed of your vehicle is too
high approaching another vehicle, the

6Operating limits



No alert is triggered in the following conditions:
– In the presence of non-moving objects (parked
vehicles, barriers, street lamps, road signs, etc.).
–

Oncoming traffic.
–


Driving on a winding road or a sharp corner
.
–

When overtaking or being overtaken by a very
long vehicle (lorry

, bus, etc.) that is detected
in the rear blind spot but is also present in the
driver’s front field of vision.
–

When overtaking quickly
.
–

In very heavy traffic: vehicles detected in
front and behind are confused with a lorry or a
stationary object.
–


If the Park
Assist function is activated.
Malfunction
If the event of a malfunction, this warning
lamp comes on in the instrument panel,
accompanied by the display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot can
be interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors, or the detection zones on
the front and rear bumpers with adhesive
labels or other objects; they may hamper
correct operation of the system.
Active Blind Spot Monitoring System
In addition to the fixed warning lamp in the door
mirror on the side in question, a correction of
trajectory will be felt if you attempt to cross
a lane marking with the direction indicator
activated, to help you avoid a collision.
This system is the combination of the Active
Lane Departure Warning System and Blind Spot
Monitoring.
These two functions must be activated and in
operation.
The speed of the vehicle must be between 40
and 87
mph (65 and 140 km/h).
These functions are especially suitable for
driving on motorways and main roads.
For more information on the Active Lane
Departure Warning System and Blind Spot
Monitoring , refer to the corresponding sections.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .
