– Vehicles in a tight bend.
– When approaching a roundabout.

– When following a narrow vehicle.
Reactivate the system when conditions allow .
Situations in which the driver is prompted to
immediately resume control:
–

Excessively sharp deceleration by the vehicle
in front of you.


– When a vehicle cuts in sharply between your
vehicle and the one in front.
Some vehicles on the road may be
poorly perceived or interpreted by the
camera and/or the radar (e.g.
truck), which
can lead to an incorrect evaluation of
distances and result in inappropriate
acceleration or braking of the vehicle.
Pay particular attention:
– When motorcycles are present and
when there are vehicles staggered across the
traffic lane.
–

When entering a tunnel or crossing a
bridge.
If any of the following malfunctions
occurs, do not use the system:
–

Following an impact on the windscreen
close to the camera or on the front bumper

.
–

If a brake lamp is not working.
If the vehicle has undergone any of the
following modifications, do not use the
system:
–

Carrying long objects on roof bars.
–


Towing.
–

Front end of the vehicle modified (for
example by adding long-range headlamps or
painting the front bumper).
–


Obstructed radar
.
Malfunction
In the event of a malfunction, dashes are
displayed (orange) instead of the speed setting.
This warning lamp comes on, accompanied by a message and an
audible signal, to confirm the malfunction.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
Lane positioning assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


The system identifies the edges of the traffic lane
and steers the vehicle to keep it inside this lane
and maintain the lateral position chosen by the
driver.
To do this, the system uses a camera placed on
the upper part of the windscreen.
This system is particularly suited to driving on
motorways and main roads.
Activation/Deactivation
The Lane positioning assist system is
automatically activated, after selecting Drive
Assist Plus mode. CarM an uals 2 .c o m

120
Driving
For more information on the Drive Assist Plus
system, refer to the corresponding section.
The selection is confirmed by the display of the
symbols on the instrument panel, representing
the steering wheel and the side lines.
The colour of the symbols depends on the
operating state of the system:
(grey)
One or more operating conditions is not
met; the system is paused.
(green)
All operating conditions are met; the
system is active.
(orange)
System malfunction.
If the driver no longer wishes to use the system
for some time, they can deactivate it by pressing
the ASSIST button again (confirmed by the
Driving aids mini-view disappearing from the
instrument panel).
The system status is saved when the ignition is switched off.
Operating conditions
– Adaptive cruise control active.
– ESC system operational.
–

ASR system activated.
–


No trailer detected.
–


No 'space-saver' spare wheel in use.
–


V
ehicle not subject to strong lateral
acceleration.
– Direction indicators off upon activation of the
system.
Cruise control
The driver must hold the steering wheel properly.
When cruise control is activated, the symbols are
displayed in green: with small steering inputs,
the system steers the vehicle and keeps it in the
position chosen by the driver in the traffic lane.
This 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
action on the brake pedal that causes the
Adaptive cruise control
system to be paused
will also cause the system to be paused.
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.
Automatic suspension
Suspension of the system is accompanied by a
specific audible signal.
–

T
riggering of the ESC system.
–

Insufficient lane detection. In this case, the
Lane keeping assist function can take over

,
and the system will reactivate itself once the
operating conditions are met again.
Paused by the driver
– Travelling outside the lane limits.
– T oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
–

Action on the brake pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).

Semi-automatic lane
changing
(with Drive 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. CarM an uals 2 .c o m

123
Driving
6The 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.
Selecting the system
Two options:
– Either when the vehicle is already driving on
an eligible road, the driver selects the system by
activating the Drive
Assist 2.0 system.
–

Or when the driver is already using Drive
Assist Plus, 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.
–


by acting on the pedals.
For more information on the Direction
indicators

, refer to the corresponding section.
Operating conditions
– Eligible roads: roads with separate
carriageways with prohibited access for
pedestrians and cyclists.
–

The line separating the lanes must be clear
enough to be identified by the system.
–


The position and speed of other vehicles must
enable the system to safely change lanes.

Authorised lane change request
When operating the direction indicator, if the
necessary conditions are met, the message
"OK?" is displayed on the instrument panel.




► After checking the surroundings, press
2-OK to confirm the start of the lane change
manoeuvre.
The message
"Stay attentive" is displayed as a
reminder that the driver is still responsible for the
manoeuvre.

CarM an uals 2 .c o m

124
Driving
The system then proceeds with the vehicle’s
lane change.
Once the manoeuvre has been carried out, the
system is automatically deactivated and the lane
positioning assist takes over.
If the direction indicator has been set beyond the
point of resistance, the driver must pull it back.
The driver must hold the steering wheel correctly.
As soon as the semi-automatic lane change
begins, the system directs the vehicle to the
target lane by small actions on the steering to
position it in the destination lane.
You can feel the steering wheel moving.
Interrupting the lane change
It is possible that while changing lane, the
necessary conditions for the operation of the
system
may no longer be met.


If this occurs before one of the wheels has
crossed the line separating the two lanes, the
system automatically returns the vehicle to
its original lane (confirmed by the display of
a manoeuvre cancellation message on the
instrument panel and an audible signal). The
system is then automatically deactivated.


If this occurs when the lane change has
started, the system prompts the driver to
immediately retake control of the vehicle (confirmed by the display of a message on the
instrument panel and an audible signal), and the
system is automatically deactivated.
Refused lane change
request
When operating the direction indicator or
pressing
2-OK, if the necessary conditions
are not met, the lines appear in orange on the
instrument panel.


The system keeps the vehicle in the original
lane. The system is deactivated and the semi-
automatic lane change is not carried out.

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

.
Below a speed of 19 mph (30 km/h),
automatic emergency braking may slow
down the vehicle to a complete stop.
Otherwise, for versions with camera only
, the
speed may be reduced by a maximum of 16
mph (25
km/h).
For versions with camera and radar, the
speed reduction may be extended to 31 mph CarM an uals 2 .c o m

6(50 km/h), if both sensors are able to detect
the thread.
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.
Deactivation/Activation
By default, the system is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
or
Direct access to the Shortcuts for driving aids .
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 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 the driving aids touch screen application is
recommended, for instance:
–

Carrying long objects on roof bars.
–


Using an automatic car wash.
–


Performing any maintenance (e.g.
changing a
wheel, working inside the engine compartment).
–

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


T
owing the vehicle.
–

Following a damage of 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).
–

A

severe crash (e.g. with airbag
deployment) is detected. CarM an uals 2 .c o m

128
Driving
In case the detection is degraded or
temporarily unavailable by environment
conditions, then a driver indication is not
displayed (because a driver action is not
requested).
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle (keep within the GVW and GTW limits
and load height limits for roof bars).
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.
► In the ADAS touch screen application,
select Functions>Automatic Braking
System .
►

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
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
(e.g.
actions on the pedals, steering wheel) 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 touch screen,
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 either of the other two.
Intelligent emergency
braking assistance (iEBA)
This function increases vehicle deceleration
if the driver does not brake enough to avoid a
collision.
This assistance is only provided if the driver
presses the brake pedal. CarM an uals 2 .c o m
