Driving
6Active Lane Keeping Assist
Refer to the General recommendations on the
use of driving and manoeuvring aids .


Using a camera located at the top of the
windscreen, the system identifies lane markings
and steers the vehicle inside this lane to keep it
in the lateral position chosen by the driver.
This function is primarily suitable for driving on
motorways and main roads.
Conditions for operation
– Adaptive Cruise Control active.
– T raffic lane marked out by lines on both sides.
–

ESC system operational.
–


ASR system activated.
–


No trailer detected.
–


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


V
ehicle not subject to strong lateral g-forces.
–

Direction indicators not activated.
Activation/Deactivation



► With the Adaptive Cruise Control with Stop &
Go function activated, press this button.
The action is confirmed by:
–

The indicator lamp in the button lighting up
green.
–


The following symbol being displayed on the
instrument panel.
The colour of the symbol on the instrument panel
depends on the operating status of the system:
(grey colour)
One or more operating conditions is not
met; the system is paused.
(green colour)
All operating conditions are met; the
system is active.
(orange colour)
System malfunction.
If the driver no longer wishes to use the system
for a while, they can deactivate it by pressing the
button again.
The indicator lamp in the button goes off and the
symbol disappears from the instrument panel.
The system status is saved when the ignition is switched off.
Cruise control
The driver must hold the steering wheel properly.
When cruise control is activated, the symbol is
displayed in green: by small steering actions,
the system directs 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.
The driver can feel movements in the steering
wheel.
The driver can change the position of the vehicle
at any time, by turning the steering wheel, which
suspends the function. The driver positions the
vehicle where they wish to in the lane. When
the driver feels that the vehicle’s position is
appropriate, they maintain it until the function
is reactivated. The system regains control by
regulating on the new 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 results in cruise

126
Driving
control being 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, you must reactivate it by
pressing the button again.
Automatic pause
– Triggering of the ESC.
– Prolonged failure to detect one of the lane limit
markings. In this case, the active lane departure
warning function can take over
, and the system
will reactivate itself once the operating conditions
are again met.
In response to action by the driver:
suspension
– Activation of the direction indicators.
– T ravelling 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).
–


Pausing of the cruise control.
–


Deactivation of the
ASR.

Active Safety Brake with Distance Alert and
Intelligent emergency
braking assistance
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 vehicle in front, a pedestrian or
,
depending on version, a cyclist.
–

reduces the vehicle's speed to avoid a
collision or limit its severity

.
The system also takes motorcyclists and animals into account; however, animals
below 0.5 m tall and objects on the road are
not necessarily detected.
This system is comprised of three functions:
–

Distance Alert.
–


Intelligent emergency braking assistance.
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a multifunctional camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not avoid the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
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 set via the Driving / Vehicle touch
screen menu.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits

The system is automatically deactivated after the use of certain "space-saver"
type spare wheels is detected (smaller
diameter).
The system is automatically deactivated
after detection of 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.
The driver must always stay in control of the
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.
Distance Alert
This function warns the driver that their vehicle is
at risk of a collision with the vehicle in front, or a
pedestrian or cyclist present in their traffic lane.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the Driving / Vehicle touch screen menu.
►

Select one of the three pre-defined
thresholds: "Far", "Normal" or "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 trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
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,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
indicating 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

130
Driving
the "Close" trigger threshold has been
selected.
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 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.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under 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 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.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function acts on the vehicle’s braking.
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.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or sharply 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.
Malfunction
In the event of a fault with the system, you
are alerted by the fixed illumination of this
warning lamp, accompanied by the display of a
message and an audible signal.
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
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.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break in case of feeling tired or at least
every 2 hours.
The function comprises the "Driver Attention
Alert" system combined with the "Driver Attention
Alert 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.
Activation / Deactivation
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory
when the ignition is switched off.
Driver Attention Alert
The system triggers an alert as soon as 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 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.

132
Driving

Conditions for operation
– Vehicle speed between 40 and 112 mph (65
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 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 intervene (for example, if
the central dividing line disappears).
Operation
Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected or a lane limit (e.g. grass border), it
makes the necessary trajectory correction 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.
The driver can prevent the correction by keeping a firm grip on the wheel (during
an avoiding manoeuvre, for example).
The correction is interrupted immediately 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
intentional and no correction is triggered during
this period.
However, with the Blind Spot Monitoring System
system activated, if the driver starts changing
lanes and another vehicle is detected in the
vehicle's blind spot, the system will correct the
trajectory even though the direction indicators
are on.
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.
The table below describes the alerts and messages displayed in different driving situations.
These alerts are not displayed sequentially.

If, while correcting the trajectory
, the system detects
that the driver has not held the steering wheel for a few
seconds, it interrupts the correction and returns control to
the driver.
– If, while correcting the trajectory , the system determines
that the correction will not be enough and that a solid line
will be crossed (orange line): the driver is warned that they
must provide additional trajectory adjustment.
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 if you have your
hands on the steering wheel.
