Driving
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a CITROËN dealer or a
qualified workshop.
Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.

Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding,
–


lengthens braking distances,
–


causes premature wear of the tyres,
–


increases fuel consumption.
The inflation pressures specified for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10
km) at
moderate speeds).
Otherwise, add 0.3
bar to the pressures
shown on the label.

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.

134
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

135
Driving
6first 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.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates subject to the following
conditions:
–

The vehicle's speed does not exceed 37 mph
(60 km/h) when a pedestrian is detected.
–


The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle or a cyclist
is detected.
– The vehicle's speed is above 6 mph (10 km/h)
(versions with camera and radar) or between
6 mph and 53 mph (10
km/h and 85 km/h)
(versions with camera only) when a moving
vehicle is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
With an automatic gearbox, in the event of
automatic emergency braking bringing the
vehicle to a complete stop, keep the brake
pedal pressed down to prevent the vehicle from
moving off again.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.
The brake pedal may vibrate slightly while the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Malfunction
A fault in the system is signalled by the fixed illumination of this warning lamp,
