Memorising speeds
Linked to the speed limiter and programmable
cruise control, this function allows speed limits
to be registered which will then be suggested
as settings for these two systems.
You can memorise several speed settings for
each system.
By default, some speed settings are already
memorised.As a safety measure, the driver must
only modify the speed settings when
stationary.
Changing a speed setting
From the Driving/Vehicle menu of
the touch screen, select " Driving
functions ", then "Memorised speed
settings ".
"MEM" button
For more information on the Speed limiter or
Cruise control , refer to the associated section.
With this button, you can select a memorised
speed setting to use with the speed limiter or
the programmable cruise control.
Drive Assist Plus
This system provides active assistance in
keeping the vehicle in position in its lane.
It results from the combination of the Adaptive
cruise control with Stop & Go function and the
Lane Positioning Assist.
These two functions must be activated and in
operation.
These functions are especially suitable for
driving on motor ways and main roads. For more information on the
Adaptive cruise
control and the Lane Positioning Assist ,
refer to the corresponding sections.
This system is a driving aid that cannot,
under any circumstances, replace driver
vigilance and respect of the speed limits
and safety distances.
The system assists the driver by operating
the steering, acceleration and braking
within the limits of the laws of physics
and vehicle per formance. Some road
infrastructure elements or vehicles present
on the road may not be properly detected
or interpreted by the camera and radar,
which may lead to an unexpected change
in direction, a lack of steering correction
and/or inappropriate management of the
acceleration or braking.

Driving

152
For this purpose there is a camera located at the
top of the windscreen, and, depending on the
version, a radar installed in the front bumper.Primarily designed for driving on main
roads and motor ways, this system only
works on moving vehicles , driving in the
same direction as your vehicle.
Principle of operation
The system automatically adapts the speed of
your vehicle to that of the vehicle in front, to
maintain a constant distance.
If the vehicle in front is driving more slowly,
the system slows, or even stops your vehicle,
using engine braking and the braking system
(for versions fitted with an automatic gearbox).
For versions fitted with the EAT8 automatic
gearbox, if traffic conditions allow and the
stop was for less than 3 seconds, your vehicle
restarts automatically.
If the vehicle in front accelerates or changes
lane, the cruise control progressively
accelerates your vehicle to return to the
programmed speed. The brake lamps illuminate as soon as
the braking system is activated with
deceleration of the vehicle.
This system is a driving aid that cannot,
in any circumstances, replace the need to
obser ve speed limits and safety distances,
nor the need for vigilance on the part of
the driver.
Some vehicles present on the road may
not be properly seen or may be poorly
interpreted by the camera and/or radar
(e.g. a lorry), which may lead to a poor
assessment of the distances and lead to
the vehicle inappropriately accelerating or
braking.
The driver must be ready at all times
to retake control of their vehicle by
permanently holding both hands on the
steering wheel and keeping their feet near
the brake and accelerator pedals.
If the driver operates a direction indicator to
overtake a slower vehicle, the cruise control
allows your vehicle to temporarily approach
the vehicle in front to assist the overtaking
manoeuvre, though never exceeding the
programmed speed.
vehicle to come to a complete stop.
For the versions fitted with the EAT8 gearbox,
your vehicle can restart automatically. The cruise control remains active after
changing gear regardless of the gearbox
type.
It manages the acceleration and deceleration
of the vehicle by automatically acting on the
engine and the braking system.
Adaptive cruise control
This system provides the following
functions:
-

A
utomatically maintains the vehicle
at the speed set by the driver.
-

A
utomatic adjustment of the
distance between your vehicle and
the one in front.
With an automatic gearbox, automatic
adjustment of the distance can cause your

The cruise control operates by day and
night, in fog or moderate rainfall.
However, it is strongly recommended that
you always keep a safe distance from
vehicles ahead, according to the driving
conditions, the weather and the road
sur face.
Use the cruise control only where the
driving conditions allow running at a
constant speed and keeping an adequate
safety distance.
Do not activate the cruise control in urban
areas where pedestrians are likely to
cross the road, in heavy traffic, on winding
or steep roads, on slippery or flooded
roads, when there is snowfall, if the front
bumper or windscreen is damaged or
when the brake lamps have failed.
In certain circumstances, it may not
be possible for the speed setting to be
maintained or even attained: loaded
vehicle, ascending a steep hill, etc.The system is not intended for the
following situations:
-

i
f the front end of the vehicle has
been modified (addition of long-range
headlamps, painting of the front
bumper),
-

d
riving on a racing circuit,
-

r
unning on a rolling road,
-

u
se of snow chains, non-slip covers or
studded tyres.
The use of mats not approved by
PEUGEOT may inter fere with the
operation of the cruise control.
To avoid any risk of jamming the pedals:
-

e
nsure that the mat is secured
c o r r e c t l y,
-

n
ever place one mat on top of another.The following situations may interfere with
the operation of the system or prevent it
from working:
-

d
riving on a winding road,
-

p
oor visibility (inadequate street
lighting, falling snow, heavy rain, dense
f o g , e t c .),
-

d

vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
-

c
amera or radar obstructed (mud, frost,
snow, condensation, etc.).
In these situations, detection performance
may be reduced.
Operation of the radar, located in the
front bumper, may be impaired by the
accumulation of dirt (dust, mud, etc.) or in
certain weather conditions (snow, frost,
e t c .) .
Do not stick any items to the radar's
protective cover.
Clean the front bumper regularly.
Clean the windscreen regularly,
particularly the area in front of the
detection camera.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle, as this could
obscure the camera.
Driving

161
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.
Malfunction
If the cruise control
malfunctions, dashes are
displayed instead of the
cruise control speed setting.
If this warning lamp comes
on, accompanied by an alert
message and an audible
signal, this confirms a
malfunction.
The adaptive cruise control deactivates
automatically if the use of a "space-saver"
type spare wheel is detected or if there is
a malfunction on the lateral brake lamps or
trailer brake lamps (for approved trailers).
Lane Positioning Assist
Have the system checked by a PEUGEOT
dealer or a qualified workshop. 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
motor ways and main roads.
This system is a driving aid that cannot,
under any circumstances, replace driver
vigilance and respect of the speed limits
and safety distances.
The system does not assess the
behaviour of other vehicles. Therefore,
the
driver must be ready at all times
to retake control of their vehicle by
permanently holding the steering wheel
with both hands and keeping their feet
near the brake and accelerator pedals.
The function cannot be used to
compensate for loss of vigilance caused
by driver inattention or fatigue. It is
recommended to take a break every two
hours.

This system is a driving aid that includes three
functions:
-
D
istance Alert (alert if there is a risk of
collision),
-
I

ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
The vehicle has a multifunctional camera
located at the top of the windscreen, and,
depending on the version, a radar located in
the front bumper. 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.
This system does not replace the need for
vigilance on the part of the driver. 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.
This system can be deactivated
or activated via the touch screen’s
Driving/Vehicle menu.
Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a message.
Operating conditions and
limits
The ESC system must not be faulty.
The ASR must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required. The following situations may interfere with
the operation of the system or prevent it
from working:
-

p
oor visibility (inadequate street
lighting, falling snow, heavy rain, dense
f o g , e t c .),
-
d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
-
c
amera or radar obstructed (mud, frost,
snow, condensation, etc.).
On versions with camera alone, this
message indicates to you that the camera
is obstructed: " Driving aids camera:
Visibility limited, see user guide".
In these situations, detection performance
may be reduced.
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.
Clean the front bumper, especially around
the radar, removing mud, snow, etc.

-

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

t

-

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.

Driving

168
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.
