12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver when one or more
tyres have a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
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.
It takes the last values

stored during
the

reinitialisation request into account. It is
therefore essential that the tyre pressure is
correct during the operation. This operation is
the driver’s responsibility.
The tyre under-inflation detection cannot, in any circumstances, 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), especially 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 energy consumption.
The inflation pressures defined 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 monthly
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.

Switching on/Pausing
► Press 1-LIMIT to select the speed limiter
mode; the function is paused (grey).
►

If the limit speed setting is suitable (most
recent speed setting programmed in the system),
press

2-I I> or 4-OK to switch the speed limiter
on (green).
►

Pressing
2-I I> again temporarily pauses the
function.
When the speed setting remains below
the vehicle's speed for a prolonged
period of time, an audible warning is emitted.
Adjusting the speed setting
You do not have to switch the speed limiter on in
order to set the speed.
To change the speed setting using the vehicle’s
current speed:
►

For steps of +/- 1 mph (1 km/h), make
successive short presses upwards/downwards
on

3 to increase/decrease.
►

For steps of +/- 5 mph (5
km/h), press and
hold upwards/downwards on 3 to increase/
decrease.
When the function is activated, it is possible to
modify the cruise speed setting based on the
speed suggested by the Road signs recognition
function, as shown on the instrument panel:
–

When passing the sign:
► Press 4-OK to save the suggested speed.
This value is then immediately shown as the new
speed setting on the instrument panel.
–

After passing the sign:
►


Press
4-OK. The message "OK?" is
displayed to confirm the request to save.
►

Press
4-OK again to save the suggested
speed. The new speed setting value is displayed
on the instrument panel.
Temporarily exceeding the
speed setting
► Fully depress the accelerator pedal.
The speed limiter is temporarily deactivated and
the displayed speed setting flashes.
►

Release the accelerator pedal to return to
below the speed setting.
When exceeding the speed is not due to the
driver's action (e.g.

in case of a steep slope), an
audible signal is triggered immediately.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the speed setting.
If necessary, apply the brakes to control your
vehicle’s speed.
When the vehicle speed returns to the speed
setting level, the speed limiter operates again:
the speed setting display becomes fixed again.

Driving
6This position is not necessarily the centre of the
lane.
You can feel the steering wheel moving.
At any time, the driver can change the position of
the vehicle by intervening on the steering wheel
and maintaining the position until the system has
taken it into account. If the chosen position is too
off-centre, an automatic re-centering manoeuvre
can occur. The system adjusts to the newly
defined position.
Pausing/Suspending the
system
The driver must act promptly if they believe that the traffic conditions or the
state of the road surface require their
intervention, by moving the steering wheel to
temporarily suspend system operation. Any
intervention on the brake pedal that causes
the Adaptive cruise control to pause will also
cause the system to pause.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding
the steering wheel, the system must be
reactivated by pressing the ASSIST button
again.

Semi-automatic lane
changing
(with Highway Driver Assist 2.0)
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
This system assists the driver in changing lanes.
To do this, it uses the camera located at the top
of the windscreen, the radar located at the front
and the four angle radars fitted in the bumpers.
The steering wheel is equipped with a hands-on detection system to avoid
distraction on the part of the driver.
For more information on the Hands-on
detection, refer to the corresponding section.
The system cannot in any circumstances replace the need for vigilance on the part
of the driver. The driver remains responsible
for their driving by monitoring their
surroundings and keeping their hands on the
steering wheel.
The driver must act promptly if they believe
that the traffic conditions or the state of the
road surface require their intervention, by
moving the steering wheel to temporarily
suspend system operation.
Any intervention on the brake pedal or the
accelerator pedal that causes the adaptive
cruise control to be paused or suspended will
also cause the system to deactivate.
System selection
Two possibilities:
– Either , when the vehicle is already driving on
an eligible road, the driver selects the system via
the Highway Driver Assist 2.0 system activation.
–

Or
, when the driver is already using Highway
Driver Assist, the vehicle suggests selecting
the system upon arriving at an eligible road by
pressing the OK button.
Activation/Deactivation

► Activate the direction indicator on the side
corresponding to the lane change, whether or
not passing the resistance point of the lighting
control stalk.
The driver can regain control of the vehicle at
any time:
–

by deactivating the direction indicator if the
vehicle has not yet crossed the line.
–


by firmly holding the steering wheel.

Driving
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own
vehicle and the object identified for the collision
risk, and the operation of the vehicle (actions on
the pedals, steering wheel, etc.) to trigger the
alert at the most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message
"Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake! " is displayed.
Level 3: a micro-braking may be given,
confirming the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed
directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically
at lower speed.
It is possible that collision 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.
If you select “Far” in the ADAS touch
screen application, then the system
warns sooner. This increases the safety but
increases also the amount of alerts, if the
legal safety distance is not kept. To reduce
the alert occurrence, you can change the
setting to “Medium” or “Near”.
Intelligent emergency
braking assistance (iEBA)
This function increases vehicle deceleration
if the driver doesn't brake enough to avoid a
collision.
This assistance is only provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called "automatic emergency
braking", intervenes after the acoustic alert if the
driver does not operate the brake pedal quickly
enough.
The system aims at reducing the speed of
impact or avoiding a collision if the driver fails to
react.
The speed will be reduced by a maximum of 16 mph (25 km/h) (versions
with camera only) or by a maximum of 31
mph (50 km/h) (versions with camera and
radar).

Driving
if the front camera or the front radar is covered
by dirt, snow, ice or anything preventing the
sensing.
In the event of a malfunction, this warning
lamp lights up 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.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
These warning lamps light up on the instrument panel and/or in the
warning lamp display for seat belts and front
passenger airbag to indicate that the driver's
and/or front passenger's seat belt is not fastened
(depending on version). The automatic braking
system is deactivated until the seat belts are
fastened.
Distraction detection
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The function comprises the "Coffee Break Alert"
system combined with the "Driver Attention
Warning" system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Activation/Deactivation
By default, the function is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
Coffee Break Alert
The system triggers an alert when it detects that the driver has not taken a
break after two hours of driving at a speed above
43 mph (70
km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 43 mph (70 km/h), the
system goes into standby.
Driving time starts being counted again once
the speed reaches above 43
mph (70 km/h).
Driver Attention Warning

The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
At a first alert level, the driver is warned by
the message "Caution!“, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Driving

Driving

A warning lamp appears in the door mirror on the
side in question:
–
fixed
, immediately when another vehicle is in
the blind spot or is approaching in an adjacent
lane.
–

flashing , after about 1 second when the
direction indicator is used.
Activation/Deactivation
It is configured in the ADAS touch screen
application.
When starting the vehicle, the
warning lamp
comes on in each mirror to indicate that the
system is activated.
The status of the system is memorised when the
ignition is switched off.
The system is automatically deactivated when towing with a towing device
approved by CITROËN.
Operating conditions
– All vehicles are moving in the same direction
and in adjacent lanes.
–

When overtaking a vehicle, the speed
difference is less than 9

mph (15 km/h).
– Traffic is flowing normally.
– When overtaking a vehicle over a certain
period of time, the vehicle being overtaken
remains in the blind spot.
Operating limits
No alert is triggered in the following conditions:
– presence of stationary objects (e.g. parked
vehicles, safety rails, lampposts, signs).
–

vehicles travelling in the opposite direction.
–


if the rear bumper is damaged.
It is possible that warnings are not given,
are given too late or seem unjustified.
This system does not replace the need for
vigilance on the part of the driver. Always
check in the mirrors and look over your
shoulders before changing lanes to avoid an
accident.
If the rear bumper is to be repainted, contact
a dealer or a qualified workshop; certain types
of paint could interfere with the operation of
the radars.
Malfunction
If the event of a malfunction, this warning
lamp comes on in the instrument panel,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
The system may be temporarily disturbed by certain weather conditions (e.g. heavy
rain, hail or extreme temperature changes).
In particular, driving on a wet road or going
from a dry to a wet area can cause false
alerts (e.g.
presence of a cloud of water
droplets in the blind spot 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 rear bumper with adhesive labels or other
objects; they may hamper correct operation of
the system.
Parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .

134
Driving
The rear parking sensors are deactivated automatically if a trailer or bicycle carrier
is connected to a towing device installed in
accordance with the Manufacturer's
recommendations.
In this case, the outline of a trailer is displayed
at the rear of the image of the vehicle.
When starting the vehicle, the graphic
and audible aids are only available after
the touch screen has started up.
Operating limits
If the boot is heavily loaded, the vehicle may tilt,
affecting distance measurements.
Malfunction
In the event of a malfunction when
changing into reverse gear, these
warning lamps light up on the instrument panel,
accompanied by the display of a message and
an audible signal (short beep).
Have it checked by a CITROËN dealer or a
qualified workshop.
Top Rear Vision
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .When reverse gear is engaged, with the engine
running, this system displays views of the
vehicle's close surroundings
on the touch screen
using a camera located at the rear of the vehicle.




The screen is divided into 3 parts with a side
menu, a contextual view and a view from above
the vehicle in its close surroundings.
The parking sensors supplement the information
in the view from above the vehicle.
Different contextual views are available:
–
Automatic zoom view
.
–

Standard view
.
–

Panoramic view
.
Depending on the context, the system chooses
the best view to display (standard or automatic
zoom).
The view type can be changed at any time
during the manoeuvre.
The system status is not saved when the ignition
is switched off.
Operating principle

Using the camera, the vehicle's close
surroundings are recorded during low speed
manoeuvres.
An image from above the vehicle in its close
surroundings is created in real time (on the side
of the screen), as the vehicle progresses.
This view makes it easier to align the vehicle
when parking and to perceive nearby obstacles.
It is automatically deleted if the vehicle remains
stationary for too long.
Configuration
In the side menu, this menu allows you to
carry out the following operations:
–

volume adjustment of the audible signal.
–


brightness adjustment.
–


contrast adjustment.
–
