Driving
Electric power is used to supplement the petrol
engine as long as there is energy left in the
battery.
Hill start assist
This system keeps the vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
The system is only active when:
–

The vehicle is completely stationary
, with your
foot on the brake pedal.
–

Certain slope conditions are met.
–


The driver
’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. Then check that the parking
brake indicator lamp and the P indicator lamp
in the electric parking brake control are on
fixed.
The hill start assist function cannot be deactivated. However, using the parking
brake to immobilise the vehicle interrupts its
operation.
Operation

Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when the
driver releases the brake pedal:
–

If mode
D or M is selected on an automatic
gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when the driver releases the
brake pedal.
Malfunction
If the event of a malfunction, these
warning lamps light up on the
instrument panel, accompanied by the display of
a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Gear shift indicator
(Depending on engine)
This system is designed to reduce fuel
consumption by recommending the most suitable
gear.
Operation
Depending on the driving situation and
the vehicle's equipment, the system may
recommend skipping one or more gears.
Gear engagement recommendations are
not to be considered mandatory. Indeed, the
configuration of the road, the traffic density and
safety remain determining factors when choosing
the best gear. Therefore, the driver remains
responsible for deciding whether or not to follow
the system’s advice.
The system cannot be deactivated.
The system is only active in mode M of
the automatic gearbox.
The information appears on the instrument panel, in the form of an arrow
and the recommended gear.
The system adapts the gear change instructions according to the driving
conditions (e.g.
slope, load) and driving style
(e.g.
power demand, acceleration, braking).
The system never suggests:
–

engaging first gear;
–


engaging reverse gear
.

6Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
red
lights, traffic jams). The engine automatically
restarts - START mode - as soon as the driver
indicates the intention of moving off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
By default, the function is activated when the
ignition is switched on.
It is configured in the ADAS touch screen
application.
or
Direct access to the Shortcuts for driving aids .
The display of a message on the instrument
panel confirms the change of state.
If the function is deactivated while the engine is
in STOP mode, it will restart immediately.

ehicle speed between 43 and 112 mph (70
and 180 km/h).
Operation
The vehicle is moving at the
speed setting and is monitoring
bends.
The system gradually decreases
the speed in the bend to
negotiate it comfortably.
Temporary driver intervention
If the driver believes that the speed is too slow or
too fast, they can act on the pedals.
Pressing the brake pedal deactivates Highway
Driver Assist 2.0, while pressing the accelerator
pedal temporarily suspends it.
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.

Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
For more information, 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 preceding vehicle, a pedestrian
or a cyclist.
–

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

.
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).
The system also takes motorcyclists into account. It may also react on animals.
Animals (especially animals smaller than
0.5

m) and objects on the road are not
necessarily detected.
This system includes three functions:
– Collision Risk Alert.
–

Intelligent emergency braking assistance
(iEBA).
–


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 driver vigilance.
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.
As soon as the system detects a potential collision, it prepares the braking
circuit. This may cause a slight noise and a
slight sensation of deceleration.

125
Driving
6Deactivation/Activation
By default, the system is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
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 without trailer.
Brake system operational.
ASR / ESP system activated.
Seat belts fastened for all passengers.
Stabilised speed on roads with no or low
curvature.
This warning lamp lights up on the instrument panel without any additional
message, to indicate that the “automatic braking
system” is not available. This is a normal
behavior indicating that a condition is not fulfilled
and which does not request the support of a
workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the
system via ADAS touch screen application is
recommended, for instance:
–

T

owing a trailer (particularly a trailer without its
own braking system).
–

Carrying long objects on roof bars.
–


Driving with snow chains.
– Using an automatic car wash.
– Performing any maintenance (e.g. changing a
wheel, working underhood).
–

Placing the vehicle on a rolling bench in a
workshop.
–


T
owing the vehicle.
–

Following a front bumper deformation (version
with radar).
–


Following
an impact to the windscreen close to
the detection camera.
The system is automatically deactivated if:
–

A

spare wheel with a too small diameter is
detected.
–

A

fault with the brake pedal switch or with
the right or left brake lamp is detected.
–

A

fault in the sensors, in the electronic or in
the brake system is detected.
–

A

trailer is detected by the equipped vehicle
hitch (with an electrical connection plug).
The system diagnoses permanently its capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions.
Examples: sensor initialization, board voltage
out of regular range, activation of stability
system…
Therefore the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not load his vehicle excessively (respect of MTAC values,
MTRA values and loading height on roof
bars).
Following an impact (e.g. a collision), the
system is automatically deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.
►

Select one of the 3 preset thresholds: “ Far

”,
“Medium” or “Near”.
The selected threshold is memorised when the
ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen

127
Driving
6Operation
The system operates subject to the following
conditions:
–
The vehicle's speed does not exceed 50
mph (80 km/h) when a pedestrian or a cyclist is
detected.
–


The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
–


The vehicle's speed is between 6 mph and
53 mph (10

km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle
is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes. During
the flashing time, the function is not available.
In the event of automatic emergency braking,
keep the brake pedal depressed, also after a
complete stop is reached, to prevent the vehicle
from rolling away.
The driver can override the "automatic emergency braking" at any time by firmly
turning the steering wheel and/or firmly
depressing the accelerator pedal.
The brake pedal may feel hard and vibrate slightly while the function is
operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Turning scenarios
