Installing ISOFIX and i-Size
universal child seats
In compliance with European regulations, this
table indicates the possibilities of installing child
Rear seats
This system prevents the child seat from tipping
forward in the event of a front impact.
This ISOFIX mounting system provides fast,
reliable and safe fitting of the child seat in the
vehicle.
To secure the child seat to the TOP TETHER:
► Remove and stow the head restraint before
installing the child seat on this seat (refit it once
the child seat has been removed).
►  Pass the upper strap of the child seat behind
the seat backrest, between the head restraint
rods.
►  Secure the upper strap hook to ring B.
►  Tighten the upper strap.
When fitting an ISOFIX child seat to the
left-hand rear seat of the bench seat,
before fitting the seat, first move the centre
rear seat belt towards the middle of the
vehicle, so as to avoid the seat interfering with
the operation of the seat belt.
An incorrectly installed child seat
compromises the child's safety in the
event of an accident.
Strictly observe the fitting instructions
provided in the user guide supplied with the
child seat.
For information about the installation
possibilities for ISOFIX child seats in your
vehicle, refer to the summary table.
Recommended ISOFIX child seats
Also consult the user guide from the child
seat’s manufacturer to find out how to
install and remove the seat.

– 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.

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 the malfunction.
Have the system checked by a dealer or a
qualified workshop.
Active 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

Activation/Deactivation



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

The indic
ator lamp in the button lighting up
green.
–

The follo
wing 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

display, the information is projected onto
the blade.
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
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 o f the ESC.
– Prolonged failure t o 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.
– Tra velling outside the lane limits.
–
