Driving
6levels of alert may be triggered and displayed on
the instrument panel.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions 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 you that
the vehicle in front is very close.
The message
"Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
you that a collision is imminent.
The message "Brake! " is displayed.
Level 3: in some cases, a vibration alert in the
form of micro-braking can be given, confirming
the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or
when the "Near " trigger threshold has been
selected.
Intelligent emergency
braking assistance (iEBA)
This function supplements braking in the event
that the driver brakes, but not enough to avoid a
collision.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
The system aims to reduce the speed of impact
or avoid a collision where the driver fails to react.
The speed will be reduced by a maximum of 12 mph (20 km/h) (versions
with camera only) or by a maximum of 31
mph (50
km/h) (versions with camera and
radar).
Operation
The system operates subject to the following
conditions:
–

The vehicle's speed does not exceed 37 mph
(60 km/h) when a pedestrian is detected.
–


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


The vehicle's speed is above 6 mph (10
km/h)
(versions with camera and radar) or between
6 mph and 53 mph (10
km/h and 85 km/h)
(versions with camera only) when a moving
vehicle is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
With an automatic gearbox, in the event of
automatic emergency braking bringing the
vehicle to a complete stop, keep the brake pedal
depressed to prevent the vehicle from moving
off again.
The driver can maintain control of the vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.

136
Driving
The brake pedal may vibrate slightly while the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
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.
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 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.
Activation/Deactivation
This function is set via the touch screen Driving/Vehicle menu.
The state of the system is memorised when the
ignition is switched off.
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).
Driver 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)).
At a first alert level, the driver is warned by the
message "Be vigilant!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: 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 markings absent, worn, hidden (snow,
mud) or multiple (roadworks);
– close to the vehicle ahead (lane markings
not detected);
– roads that are narrow, winding, etc.
Active lane departure
warning system
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

137
Driving
6At a first alert level, the driver is warned by the
message "Be vigilant!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message "Dangerous
driving: 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 markings absent, worn, hidden (snow
,
mud) or multiple (roadworks);
–

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


roads that are narrow
, winding, etc.
Active lane departure warning system
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).
T
o 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 in both hands.
–


Direction indicators not activated.
–


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 in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line 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.

138
Driving
However, with the Blind spot monitoring system
activated, if the driver is about to change lanes
while another vehicle is detected in the blind
spots of their vehicle, a trajectory correction is
initiated by the system despite the activation of
the direction indicators.For more information on the Blind spot
monitoring system, refer to the corresponding
section.
If the system detects that the driver is not
holding the wheel firmly enough during
an automatic correction of trajectory, it
interrupts the correction. An alert is triggered
to encourage the driver to take back control of
the vehicle.
Driving situations and related alerts
To receive all the necessary information on the instrument panel, first select the " Driving" display mode.

"Put your hands back on the steering wheel" –

If, during the
correction, the system detects that the
driver has not held the steering wheel for a few seconds, it
stops the correction and returns control to the driver.
– During the trajectory correction, the system determines
that the correction will not be enough: the driver is warned
that they must
provide additional trajectory correction.
The duration of audible warnings will increase if multiple
corrections are performed in quick succession. The
warning will become continuous, persisting until the driver
responds.
This message may also be displayed with your hands on
the steering wheel.

Blind spot monitoring
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This system warns the driver of a potential
danger posed by the presence of another vehicle
(car, lorry, motorcycle) in the vehicle's blind
spots (areas hidden from the driver's field of
vision) using sensors located on the sides of the
bumpers.


The warning is given by a fixed warning lamp
that appears in the door mirror on the side in
question:
–

immediately
, when being overtaken;
–

after a delay of about one second, when
overtaking a vehicle slowly

.
Activation/Deactivation
It is set via the Driving/Vehicle touch
screen menu.
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 PEUGEOT.
Operating conditions

– presence of stationary objects (e.g. parked
vehicles, safety rails, lampposts, signs).
–

vehicles travelling in the opposite direction.
–


on winding roads or in case of sharp turns.
–


when overtaking or being overtaken by a
very long vehicle (e.g.

truck, bus), which is both
detected in a blind spot from behind and present
in the driver's field of vision from the front.
–

quick overtaking manoeuvre.
–


very heavy traffic: vehicles detected in front
and behind are confused with a lorry or a
stationary object.
–


activation of the
Park Assist or Full Park
Assist
function.
Malfunction
If the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
The system may be temporarily disturbed by certain climatic conditions (e.g. rain,
hail).
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.

142
Driving
Take care not to cover the warning zone in
the door mirrors, or the detection zones on
the front and rear bumpers with adhesive
labels or other objects; they may hamper
correct operation of the system.
Active Blind Spot Detection
In addition to the fixed warning lamp in the
door mirror on the side in question, a trajectory
correction will be felt if you attempt to cross
a lane marking with the direction indicator
activated, to help you avoid a collision.
This system is a combination of the Active
lane departure warning system and Blind spot
monitoring functions.
These two functions must be activated and in
operation.
The vehicle speed must be between 43 and
87 mph (70 and 140 km/h).
These functions are especially suitable for
driving on motorways and main roads.
For more information on the Active lane
departure warning system and Blind spot
monitoring , refer to the corresponding sections.
Parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


This system detects and signals the proximity of
obstacles (e.g.
pedestrian, vehicle, tree, barrier)
using sensors located in the bumper.
Rear parking sensors
► Engage reverse gear to start the system
(confirmed by an audible signal).
The system is switched off when reverse gear is
disengaged.
Audible assistance

The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.


Depending on version, in the example shown,
only the obstacles present in the shaded area
will be signalled by the audible assistance.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalDepending on version, with
PEUGEOT Connect Radio or
PEUGEOT Connect Nav, pressing this button
opens the window for adjusting the volume of
the audible signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, by
displaying bars on the screen whose location
represents the distance between the obstacle
and the vehicle (white: more distant, orange:
close, red: very close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of the
vehicle is below 6 mph (10 km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6 mph (10 km/h).
The sound emitted by the speaker (front or rear) locates the obstacle relative to
the vehicle, whether in front of or behind it on
its path.
