In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
-
t
owing a trailer,
-

c
arrying long objects on roof bars or roof
rack,
-
w

ith snow chains fitted,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling road
in a workshop,
-

t
owed vehicle, engine running,
-

f
ollowing impact to the windscreen close to
the detection camera.
The system is automatically deactivated
after detecting the use of certain "space-
saver" type spare wheels (smaller
diameter).
The system is automatically deactivated
after detecting a fault with the brake pedal
switch or with at least two brake lamps.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of
your vehicle and be prepared to react at
any time to avoid an accident. After an impact, the function automatically
stops operating. Contact a PEUGEOT
dealer or a qualified workshop to have the
system checked.
If the front bumper is to be repainted or
retouched, contact a PEUGEOT dealer
or a qualified workshop. Certain types of
paint could inter fere with the operation of
the radar.
Distance Alert
It warns the driver if their vehicle is at risk of
collision with the vehicle in front, a pedestrian
or a cyclist present in their traffic lane.
Modifying the alert trigger
threshold
This threshold determines how you wish to
be alerted of the presence of a moving or
stationary vehicle in front of you, a pedestrian
or a cyclist present in your traffic lane.
The current threshold can be
modified via the touch screen’s
Driving/Vehicle menu. You can select one of three predefined
thresholds:
-
"
Distant ",
- "
Normal ",
- "
Close ".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of
alert can be triggered and displayed in the
instrument panel.
They take account of the vehicle dynamics, the
speed of your vehicle and the one in front, the
environmental conditions, the operation of the
vehicle (cornering, actions on the pedals, etc.)
to trigger the alert at the best moment.
Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The message " Vehicle close" is
displayed.
Level 2 (red) : visual and audible
alert, warning you that a collision is
imminent.
The message " Brake!" is displayed.
Level 3 : finally, in some cases, a
haptic alert in the form of micro-
braking may be given to confirm the
risk of collision.

Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid
a collision, this system will supplement the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
Active Safety Brake
Operation
The system operates under the following
conditions:
-
T
he vehicle's speed does not exceed 37 mph
(60 km/h) when a pedestrian is detected.
-

T
he vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle or a
cyclist is detected. If the camera and/or radar have
confirmed the presence of a vehicle,
a pedestrian or a cyclist, this warning
lamp flashes (for about 10 seconds)
when the function is acting on the
vehicle's brakes.
With an automatic gearbox, in the event of
automatic emergency braking until the vehicle
comes to a complete stop, keep the brake
pedal pressed down to prevent the vehicle from
starting off again.
With a manual gearbox, in the event of
automatic emergency braking until the vehicle
comes to a complete stop, the engine may stall.
This function, also called automatic emergency
braking, inter venes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
frontal collision by your vehicle where the driver
fails to react. The driver can maintain control of the
vehicle at any time by sharply turning
the steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained for
1
to 2 seconds.
-

T
he vehicle's speed must be 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 alone) when
a moving vehicle is detected.
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 never
displayed for a stationary obstacle or
when the " Close" trigger threshold has
been selected.

169
Malfunction
In the event of a fault with the system,
you are alerted by the continuous
illumination of this warning lamp,
accompanied by the display of a
message and an audible signal.
Fatigue detection system
Take a break as soon as you feel tired or at
least every two hours.
The function comprises the "Driver Attention
Warning" system combined with the "Driver
Attention Alert".These systems cannot in any circumstances
replace the need for vigilance on the part of
the driver who must remain in control of their
decisions. In no case can these systems
keep the driver awake or prevent them from
falling asleep at the wheel.
It is the driver’s responsibility to stop if they
feel tired.
Activation/Deactivation
These functions are activated and
deactivated in the Driving /Vehicle
menu of the touch screen.
The state of the system is memorised when the
ignition is switched off.
Driver Attention Warning
The system triggers an alert once it
detects that the driver has not taken
a break after two hours of driving at
a speed above 40 mph (65
km/h).
This alert is issued via the display of a
message encouraging you 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:
-

e

ngine running, the vehicle has been
stationary for more than 15 minutes,
-

t

he ignition has been switched off for a few
minutes,
-

t

he driver's seat belt is unfastened and their
door is open. As soon as the speed of the vehicle drops
below 40 mph (65
km/h), the system goes
into standby.
The driving time is counted again once the
speed is above 40 mph (65 km/h).
Driver Attention Alert
This system is particularly suited to fast roads
(speed higher than 40 mph (65
km/h)).
Using a camera placed at the top
of the windscreen, the system
assesses the driver's level of
vigilance by identifying variations
in trajectory compared to the lane
markings.
If these warning lamps come on after
the engine has been switched off
and restarted, contact a PEUGEOT
dealer or a qualified workshop to
have the system checked.

Driving

170
After three first level alerts, the system triggers
a new alert with the message "Take a break!",
accompanied by a more pronounced audible
signal. When the system interprets the behaviour of
the vehicle as indicating a certain fatigue or
inattention threshold on the part of the driver,
it triggers the first level of alert.
The driver is then alerted by the message
" Ta k e c a r e ! ", accompanied by an audible
signal.
Active Blind Spot
Monitoring System
In addition to the fixed warning lamp in the door
mirror on the side in question, a correction of
trajectory will be felt if you attempt to cross a
lane marking with the direction indicators on,
to
help you avoid a collision.
This system is the combination of the Active
Lane Keeping Assistance and Blind Spot
Detection.
These two functions must be activated and in
operation.
The speed of the vehicle must be between
40
and 87 mph (65 and 140 km/h) inclusive.
These functions are especially suitable for
driving on motor ways and main roads.
For more information on the Active Lane
Keeping Assistance and Blind Spot
Detection , refer to the corresponding sections.
This system is a driving aid which cannot,
in any circumstances, replace the need for
vigilance on the part of the driver.
In certain driving conditions (poor road
sur face 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:
-
p
oor visibility (inadequate lighting of
the roadway, falling snow, heavy rain,
dense fog, etc.),
-

d

azzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
-

w

indscreen area located in front of the
camera: dirty, misted up, frost-covered,
snow-covered, damaged or covered by
a s t i c ke r,
-
l

ane markings absent, worn, hidden
(snow, mud) or multiple (roadworks,
e t c .),
-

c

lose to the vehicle ahead (lane
markings not detected),
-

r

oads that are narrow, winding, etc.
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
Driving

171
Active Lane Keeping
Assistance
Using a camera located at the top of the
windscreen to identify lane markings on the
ground and the edges of the road (depending
on version), the system corrects the trajectory
of the vehicle while alerting the driver if it
detects a risk of involuntarily crossing a line or
hard shoulder (depending on version).
This system is particularly useful on motor ways
and main roads.
Conditions for operation
The speed of the vehicle must be between
40 mph and 112 mph (65 km/h and 180 km/h).
The driver must hold the steering wheel with
both hands.
The change of trajectory must not be
accompanied by operation of the direction
indicators.
The ESC system must be activated and fault-
free. This system is a driving aid that cannot,
in any circumstances, replace the
driver’s own vigilance. The driver must
remain in control of the vehicle under all
circumstances.
The system helps the driver only when
there is a risk of the vehicle involuntarily
wandering from the lane it is being driven
in. It does not manage the safe driving
distance, the speed of the vehicle or the
brakes.
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 inter vene
(if lane markings disappear, for example).
It is necessary to obser ve the driving
regulations and take a break every two
hours.
Operation
Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected on the ground or a lane limit (e.g.
grass border), it makes the correction to the
trajectory necessary to return the vehicle to its
initial path.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction. If the driver wishes to maintain the
trajectory of the vehicle, they can prevent
the correction by keeping a firm grip on
the wheel (during an avoiding manoeuvre,
for example).
The correction is interrupted if the
direction indicators are operated.
While the direction indicators are on and for
a few seconds after switching them off, the
system considers that any change of trajectory
is voluntary and no correction is triggered
during this period.
However, with the Blind Spot Detection
activated, if the driver starts changing lanes
and another vehicle is detected in the vehicle's
blind spot, the system will correct the trajectory
of the vehicle even though the direction
indicators are on.
For more information on the Blind Spot
Detection , refer to the corresponding section.

172
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.
