Driving
6road 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.
–


Drive
Assist 2.0 activated.
–

Lane positioning assist activated.
–


V
ehicle speed between 43 and 112 mph (70
and 180 km/h).
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.


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.

140
Driving
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.

deactivates itself if there is no response from
the driver.
Malfunction
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 PEUGEOT dealer or a

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

143
Driving
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.
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.
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).

144
Driving
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.
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.

145
Driving
6Below 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
(50

km/h), if both sensors are able to detect
the thread.
Operation
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.
With an automatic gearbox or drive selector, 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.
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 override the automatic emergency braking at any time by
strongly turning the steering wheel (evasive
manoeuver) and/or by firmly pressing 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
Crossing road with another vehicle

The system may operate when the vehicle is
turning and detects another vehicle, on the
adjacent lane, approaching from the opposite
direction if:
–
The corresponding direction indicator is
activated.
–


Then the vehicle is about to cross the path of
another vehicle.
–


The vehicle speed is between 3 and 12
mph
(5 and 20
km/h).
–

A
collision on the side of the other vehicle is
probable.
Crossing road with a pedestrian

The system may operate when the vehicle
is turning left or right and detects a crossing
pedestrian if:
–

The pedestrian is crossing in front of the
vehicle.
–


The pedestrian can clearly be detected by the
sensors.
–


The scenery is detectable by the sensors (e.g.
brightness, contrast vs background).

146
Driving
– The vehicle speed is between 3 and 15 mph
(5 and 25 km/h).
Deactivation/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.
The system cannot be deactivated above 10 km/h.
Malfunction
This warning lamp lights up on the instrument panel with the message
"Driving Assistance Sensor blind: Clean
sensor, see User Manual" if the sensor is
masked.
This is a normal behavior, which does not
request the support of a qualified workshop.
In this case, stop the vehicle and verify if the
front camera or the front radar is covered by dirt,
mud, sand, snow, ice or anything preventing the
sensing.
The system is operational again after the
detection field has been cleaned.
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 PEUGEOT dealer or a
qualified workshop.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a PEUGEOT
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 "Driver Attention
Warning" system combined with the "Driver
Attention Warning by Camera" 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.
Driver Attention Warning
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).

147
Driving
6Driver Attention Warning by
Camera


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)).
The system may perform a learning procedure for up to 30 minutes after the
start of the monitoring.
During this period, the driver's individual
driving behaviour is analysed and no alert is
given.
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 at
risk: Take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
–

Lane positioning assist is active.
–


poor visibility (e.g.
inadequate street
lighting, heavy rain, thick fog, snowfall).
–

dazzle (e.g.
headlamps of an oncoming
vehicle, low sun, reflections on a damp road,
leaving a tunnel, alternating shade and light).
–

windscreen area located in front of the
camera (e.g.

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

lane markings absent, worn, hidden
(e.g.

snow, mud, dead leaves) or multiple
(roadworks).
–

close to the vehicle ahead (lane markings
not detected).
–


roads that are narrow
, winding.
Deactivation/Activation
By default, the function is automatically activated
at every engine start.
The settings are changed via the ADAS
touch screen application.
or
Direct access to the Shortcuts for driving aids .
Deactivation is confirmed by the
illumination of this indicator lamp on the
instrument panel.
Malfunction
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 PEUGEOT dealer or a
qualified workshop.
This warning lamp lights up on the instrument panel with the message
"Driving Assistance Sensor blind: Clean

masked.
This is a normal behavior, which does not
request the support of a qualified workshop.
In this case, stop the vehicle and verify if the
front camera is covered by dirt, mud, sand,
snow, ice or anything preventing the sensing.
The system is operational again after the
detection field has been cleaned.

148
Driving
Lane keeping assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on
motorways and main roads.


Operating conditions
– Vehicle speed between 43 and 112 mph (70
and 180 km/h).
–

Road marked with a central dividing line.
–


Steering wheel held with both hands.
–


Direction indicators off upon activation of the
system.
–


ESC system activated and operational.
The system helps the driver only if there is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
The driver must hold the steering wheel with
both hands so that they can maintain control
when the conditions no longer allow the
system to intervene (e.g.
in the event that
the central dividing line marking on the road
surface disappears).
Operation
As soon as the system identifies a risk of
involuntarily crossing one of the lane markings
detected on the ground or a lane boundary
(e.g.
grass verge), it performs the trajectory
correction necessary to restore the vehicle to its
original lane.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during trajectory correction.
The driver can prevent the correction by firmly holding the steering wheel
(e.g.
during an emergency manoeuvre).
The correction is interrupted immediately if
the direction indicators are operated.
While the direction indicators are activated and
for a few seconds after switching them off, the
system considers that a change of trajectory is
intentional and no correction is triggered during
this period.
Driving situations and related alerts
The table below describes the alerts and messages displayed in different driving situations.
The actual order of display of these alerts may be different.
