Limits of operation
The system cannot exceed the limits of the
laws of physics.
It is recommended that the system be
deactivated when the "space-saver" spare
wheel is in use.
The system should not be activated when
towing a trailer.
In certain critical situations, the system will
encourage the driver to immediately take back
control:
-
i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle
and the vehicle in front. As the radar's field of detection is quite narrow,
it is possible that the system may not detect:
-

v
ehicles of reduced width (motorcycles,
scooters...),
-

v
ehicles not running in the middle of the
lane,
-
v

ehicles entering a corner,
-
v

ehicles suddenly pulling out.The cruise control does not take account of:
-

p
edestrians, cyclists, animals,
-

s
tationary vehicles (traffic jam, red light,
breakdown...),
-

v
ehicles crossing a junction,
-

v
ehicles driving in the opposite direction.

Operating fault
Have the system checked by a PEUGEOT
dealer or a qualified workshop.In the event of a fault with the cruise
control, you are alerted by the
illumination of this warning lamp
and the display of a message in the
instrument panel, accompanied by an
audible signal.
The cruise control operates by day and at
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 at an adequate safe
distance.
Do not use the cruise control in urban
areas, heavy traffic, on winding or steep
roads or on slippery or flooded sur faces.
In certain circumstances, it may not
be possible for the speed setting to be
maintained or even attained: loaded
vehicle, ascending a steep hill, ... The system is not intended for driving in the
following situations:
-

t

he front end of the vehicle has been
modified (addition of driving lamps),
-

d

riving on a racing circuit,
-

r

unning on a rolling road,
-
u
se of snow chains or non-slip covers.
As a safety measure, do not use the
system if the brake lamps are faulty.
Do not use the system if the front
bumper is damaged.
The operation of the radar, located in the
front bumper, may be disturbed in certain
weather conditions, for example: with
accumulations of snow, ice, mud, ...
Clean the front bumper, removing the snow,
mud, ... 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 mats are secured correctly,
-

n

ever fit one mat on top of another.

Distance alert and Active Safety Brake
This system 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).
Points on the Active Safety Brake
function
The speed of the vehicle must be between 3
and 87 mph (5 and 140 km/h) when a moving
vehicle is detected.
The speed of the vehicle must not be higher
than 50 mph (80 km/h) when a stationary
vehicle is detected.
The speed of the vehicle must not be higher
than 36 mph (60 km/h) when a pedestrian is
detected.
The DSC system must not be deactivated or
faulty.
All occupants must have fastened their seat
belts.
Driving at steady speed on roads with few
bends is required.
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 avoid the need for
vigilance on the part of the driver.
The vehicle is fitted with a radar located in the
front bumper and a camera at the top of the
windscreen.
Conditions for activation and operation
The system is active from about 4 mph (7 km/h)
and is deactivated below about 3 mph (5 km/h).
It takes account of:
-
r
egistered vehicles running in the same
direction or stationary,
-

p
edestrians present in the traffic lane
(bicycles, motorcycles, animals and objects
on the road are not necessarily detected).
Distance aler t: it warns the driver if their
vehicle is at risk of collision with the
vehicle in front or a pedestrian present in
their traffic lane.
Intelligent emergency braking assistance:
it completes the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it inter venes following
the aler t if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, it contributes
towards avoiding a collision or limiting
its severity by reducing the speed of your
vehicle. Following an impact, the system
is automatically disabled; contact
a PEUGEOT dealer or a qualified
workshop to have the system checked.

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.
Because of limits in the operation of the
system, it is possible that warnings are
not given, are given too late or seem
unjustified.
Consequently, the driver must always
remain attentive and able to react at any
time to avoid an accident.
Distance alert
Level 1: visual alert only, signalling
to you that the vehicle in front is very
close.
The message " Vehicle close" is
displayed.
Limits of operation
In the following cases, it is recommended
that the system be deactivated in the vehicle
configuration menu:
-

w
hen towing a trailer or caravan,
-

w
hen carrying long objects on roof bars or
a roof rack,
-

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

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

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-

f
ollowing impact damage to the windscreen
close to the detection camera,
-

i
f the front bumper has been damaged,
-

i
f the brake lamps are not working. This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front.
Level 2: visual and audible alert,
warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment. 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
di r e c t l y.
Important
: the level 1 alert is never
displayed if the " Close" threshold has
been selected.

Modifying the alert trigger
threshold
This threshold determines how you wish to be
warned of the presence of a vehicle moving
or stationary in front of you, or a pedestrian
present in your traffic lane.
The current threshold can be modified via the
vehicle configuration menu in the screen.
You can select one of three thresholds:
- "Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to
avoid a collision, this system will complete 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
This function, also called automatic emergency
braking, aims to reduce the speed of impact or
avoid a frontal collision by your vehicle where
the driver fails to react.
Using a radar and a camera, this function acts
on the vehicle's braking system.If the radar and the camera have
confirmed the presence of a vehicle
or a pedestrian, this warning lamp
flashes once the function is acting on
the vehicle's brakes.
Important
: if operation of the
automatic emergency braking is
triggered, you should take back
control of your vehicle and brake
with the pedal to add to or finish the
automatic braking action.
The driver can take back 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.
With a manual gearbox, in the event
of the automatic emergency braking
bringing the vehicle to a complete stop,
the engine may stall.
With an automatic gearbox, in the event
of the automatic emergency braking
bringing the vehicle to a complete stop,
keep the brake pedal pressed to stop
the vehicle moving off again.
The point at which braking is triggered
may be adjusted according to the
reaction from the driver, such as
movement of the steering wheel or
pressing the accelerator pedal.

Assisted Lane Departure Warning System
Using a camera placed at the top of the windscreen to identify lane markings on the ground, this system corrects the trajectory of the vehicle while
alerting the driver if it detects a risk of involuntary crossing of a line.
This system is particularly useful on motor ways and main roads.
Conditions for operation
The speed of the vehicle must be between 40
and 112 mph (65 and 180 km/h).
The carriageway must have at least one lane
marking (solid or broken) on the ground.
The driver must hold the wheel with both
hands.
The change of trajectory is not accompanied by
operation of the direction indicators.
The ESC system must be activated.This system is a driving aid which
cannot, in any circumstances, replace
the need for vigilance on the part of the
driver.
The driver remains responsible for the
vehicle in 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 on.
It does not manage the safe driving
distance, the speed of the vehicle or the
brakes.
The driver must hold the steering wheel
in a way that allows control to be taken
back in circumstances where the system
is not able to intervene (where there are
no lane markings, for example).
It is necessary to observe the driving
regulations and take a break every
two
hours.

Park Assist
This system provides active assistance with
parking. It detects a parking space then
operates the steering to park in the space.
It operates the steering while the driver
manages the accelerator, brakes, gears and
clutch (manual gearbox). During phases of
entry into and exit from a parking space, the
system provides visual and audible information
to the driver in order to make the manoeuvres
safe. It may be necessary to move for wards
and backwards more than once.During a manoeuvre, the steering
wheel turns quickly: do not hold the
steering wheel, do not place your
hands between the spokes of the
steering wheel and take care with
loose and bulky clothing (scarves, ties,
handbags...) - Risk of injury!
When Park Assist is activated, it
prevents a change to STOP mode of
Stop & Start. In STOP mode, activation
of Park Assist restarts the engine.
This manoeuvring assistance system
cannot, in any circumstances, replace
the need for vigilance on the part of the
driver.
The driver must remain in control of their
vehicle ensuring that the space remains
clear throughout the manoeuvre.
In some circumstances, the sensors may
not detect small obstacles located in
their blind spots.
The driver can take control at any time by
gripping the steering wheel. The Park Assist system provides assistance for
the following manoeuvres:
A.
E

ntry into a parallel parking space
B.

Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.
Advice on installation
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face
on the side of the road.
F

A
pply the parking brake and position any
wheel chocks to prevent movement of your
vehicle.
F

F
it the chains following the instructions
provided by the manufacturer.
F

M
ove off gently and drive for a few
moments, without exceeding 30 mph
(50


km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
For more information on snow chains, contact a
PEUGEOT dealer or a qualified workshop.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.
The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.
Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road sur face. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.
