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).

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.

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).

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).
