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

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

Situations in which the driver must pause the
cruise control system:


– Vehicles in a tight bend.
– When approaching a roundabout.

– When follo wing a narrow vehicle.
Reactivate cruise control when conditions permit.
Situations in which the driver is prompted to
immediately resume control:
–

Ex
cessively sharp deceleration by the vehicle in
front of you.


– When a vehicle cuts in sharply between your
vehicle and the one in front.

–

F

ront end of the vehicle modified (for
example by adding long-range headlamps or
painting the front bumper).
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
– Adaptive C ruise Control active.
– ESC s ystem operational.
–

ASR s
ystem activated.
–

No trailer det
ected.
–

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

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.
–

T
oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
–
