Manual guide-me-home lighting goes off
automatically after a period of time.
Welcome lighting
When the vehicle is unlocked in low light
conditions and the "Automatic illumination of
headlamps" function is activated, this system
automatically switches on:
–

O
n the outside, sidelamps, dipped beam
headlamps and door mirror spotlamps.
–

Inside
, courtesy lamps and footwell lighting.
Activation / deactivation and adjustment
of the duration of the welcome lighting are
set via the Driving / Vehicle touch screen menu.
Door mirror spotlamps
These spotlamps facilitate access to the vehicle
by lighting the ground near the front doors.
The spotlamps come on automatically:
–

when the v
ehicle is unlocked.
–

when a door is opened.
– when a reque st to locate the vehicle is received
from the remote control.
They also come on with the welcome lighting and
guide-me-home lighting functions.
They go off automatically after 30 seconds.
Automatic headlamp
dipping
When the ring is in the "AUTO” position, this
system automatically switches between dipped
and main beam headlamps according to the
lighting and traffic conditions, using a camera
located at the top of the windscreen.


This system is a driving aid.
The driver remains responsible for the
vehicle's lighting, its correct use for the
prevailing conditions of light, visibility and
traffic, and for observation of driving and
vehicle regulations.
The system becomes operational when
the vehicle exceeds 16 mph (25 km/h).
When the speed falls below 9 mph (15 km/h),
the function is no longer operational.
Activation/Deactivation
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory when
switching off the ignition.
Operation
If the ambient light level is sufficient and/or the
traffic conditions do not allow the main beam
headlamps to be lit:
– The dipped beam headlamp s
remain lit. These indicator lamps
come on on the instrument panel.
If the ambient light level is very low and traffic
conditions permit:
– The main beam headlamp s come
on automatically. These indicator
lamps come on on the instrument panel.
The function is deactivated if the fog lamps are
switched on or the system detects dense fog.
When the fog lamps are switched off or the
vehicle leaves the area of dense fog, the function
is automatically reactivated.
This indicator lamp goes out when the
function is deactivated.

58Lighting and visibility04
Pause
If the situation requires a change of headlamp
beam, the driver can take over at any time.
► A "headlamp flash" pauses the function:
•

If the "
AUTO" and "Dipped beam" indicator
lamps were on, the system changes to main
beam.
•

If the "
AUTO" and "Main beam"
indicator lamps were on, the system changes
to dipped beam.
To reactivate the system, flash the headlamps
again.
The system may be disrupted or not work
correctly:
–

When visibility c
onditions are poor
(snowfall, heavy rain, etc.).
–

If the windscreen in fron
t of the camera is
dirty, misted or obscured (for example, by a
sticker).
–

If the v
ehicle is facing highly reflective
signs.
When the system detects thick fog, it
temporarily deactivates the function.
The system is not able to detect:
–

R

oad users that do not have their own
lighting, such as pedestrians.
–

V

ehicles whose lighting is obscured (for
example, vehicles driving behind a safety
barrier on a motorway).
–

V

ehicles at the top or bottom of a steep
slope, on winding roads, on crossroads.
Clean the windscreen regularly,
particularly the area in front of the
camera.
The internal surface 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
obstruct the detection camera.
DS MATRIX LED VISION
Available only on versions equipped with Full LED
headlamps with the Matrix Beam function.
This system automatically adapts the main
beam according to the driving conditions, so that
optimum illumination is maintained for the driver,
without causing a nuisance to other road users.
The driver remains responsible for the
vehicle's lighting, its correct use for the
prevailing conditions of light, visibility and
traffic, and for observation of driving and
vehicle regulations.
The system is active from 25 mph
(40 km/h) and deactivates below 12 mph
(20 km/h).
Operation
Using a camera, the system detects the driving
conditions (brightess, lights from oncoming or
followed vehicles, road turns) and adapts the
beams of the main headlamps accordingly.
The modules that make up the main beams
switch on and off gradually, segment by segment,
depending on the driving conditions detected:
Followed vehicle


When approaching a vehicle from behind, only
those lamp segments directed at the followed
vehicle go off, thereby creating a "tunnel" so as
not to dazzle its driver.
Oncoming vehicle


When an oncoming vehicle approaches, only
those lamp segments directed at this vehicle
go off, thereby creating a "tunnel" during the
duration of the approach.
Nominal main beam lighting is restored as soon
as the vehicle is no longer detected by the system.
Entering an illuminated area
At the entrance to an illuminated area (for
example, a town), the lamp segments are
gradually switched off from the outside to the
inside of the vehicle to switch to the dipped
beams.
Exiting an illuminated area
The lamp segments gradually light up from the
inside to the outside of the vehicle to restore the
main beams.
Activation/Deactivation
►  Turn the lighting control stalk ring to the
"AUTO" position.
This indicator lamp comes on in the
instrument panel.
The function can be activated and
deactivated in the Driving / Vehicle touch
screen menu.
When deactivated, the lighting system changes to
"automatic illumination of lamps" mode.
The status of the system remains in the memory
when the ignition is switched off.
Pause
If the situation requires a change of headlamp
beam, the driver can take over at any time.

Malfunction
If a fault occurs with the adaptive
headlamp lighting or the camera, this
warning lamp is displayed in the instrument
panel, accompanied by an audible signal and a
message.
Contact a dealer or a qualified workshop.
Do not cover the sunshine sensor, linked
to the rain sensor and located at the top
centre of the windscreen behind the interior
rear view mirror; the associated functions
would no longer be controlled.
The system may suffer interference or not
work correctly:
–

under c
onditions of poor visibility (snow,
heavy rain, etc.),
–

if the windscreen in fron
t of the camera is
dirty, misted or obscured (for example, by a
sticker, etc.),
–

if the v
ehicle is facing highly reflective signs
or safety barrier reflectors.
It is recommended to deactivate the function
in foggy or snowy conditions or in case of
heavy mist.
The function temporarily deactivates when
the system detects thick fog or when you
switch on the foglamps. This is signalled by
the extinction of the indicator lamp in the
instrument panel.
The system is not able to detect:
–

road users tha
t do not have their own
lighting, such as pedestrians,
–

v
ehicles whose lighting is obscured (for

– Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
Tyres
►  Check the tyre pressures of the towing vehicle
and of the trailer, observing the recommended
pressures.
Lighting
►  Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine towing device is used, the
rear parking sensors will be deactivated
automatically to avoid the audible signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►  Reduce speed and lower the engine speed to
limit heating up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use of
engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine immobiliser
system, with a code that must be recognised in
order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a dealer.
Starting/Switching off the
engine
The electronic key must be present in the
passenger compartment.
For versions equipped with Proximity Keyless
Entry and Start, the electronic key is also
detected in the boot.
If it is not detected, a message is displayed.
Move the electronic key so that the engine can
be started or switched off.
If there is still a problem, refer to the "Key not
detected - Back-up starting or Back-up switch-
off" section.

Driving06
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.
►  Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
►  If it is not possible to make this check
immediately, drive carefully at reduced speed.
►  In the event of a puncture, use the temporary
puncture repair kit or the spare wheel (depending
on equipment).
The alert is kept active until the system is
reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system is
reinitialised via the Driving / Vehicle touch
screen menu..
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Malfunction
These warning lamps come on in
the event of a malfunction.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a dealer or a
qualified workshop.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the feet
close to the pedals and take a break every two
hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.),
in certain difficult weather conditions (very
heavy rain, snow) or if the bumper is damaged.
If the front bumper is to be repainted, contact
a dealer or a qualified workshop; certain types
of paint could interfere with the operation of
the radar.


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or masked
by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a dealer or a qualified workshop
to recalibrate the camera; otherwise, the
operation of the associated driving aids may
be disrupted.
Other cameras
The images from the camera(s) displayed
on the touch screen or on the instrument panel
may be distorted by the relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate

Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or masked
by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a dealer or a qualified workshop
to recalibrate the camera; otherwise, the
operation of the associated driving aids may
be disrupted.
Other cameras
The images from the camera(s) displayed
on the touch screen or on the instrument panel
may be distorted by the relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of snow
or dead leaves on the road or in the event of
damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer be
detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away from
the radar, sensors and cameras.
Mats
The use of mats not approved by the
Manufacturer may interfere with the operation
of the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
–

Ensure tha
t the mat is secured correctly.
–

Ne
ver fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
in the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a dealer or a qualified
workshop.
Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the use
of driving and manoeuvring aids.
