Ease of use and comfort
Correct driving position
For safety reasons, adjustments must
only be made when the vehicle is
stationary.
Before taking to the road and to make the most
of the ergonomic layout of the instruments and
controls, carry out these adjustments in the
following order:
–

head restraint height.
–


seat backrest angle.
–


seat cushion height.
–


longitudinal seat position.
–


steering wheel height and reach.
–


rear view mirror and door mirrors.

Once these adjustments have been
made, check that the instrument panel
can be viewed correctly from your driving
position.
Front head restraints
Adjusting the height

Upwards:
► Pull the head restraint up to the desired
position; you can feel the head restraint clicking
into position.
Downwards:
►

Press lug
A to lower the head restraint.
The head restraint is correctly adjusted when its upper edge is level with the top
of the head.
Removing a head restraint
► Tilt the backrest to the rear to make it easier
to remove the head restraint.
►

Pull the head restraint fully up.
►


Press lug
A to release the head restraint and
raise it fully.
►

Stow the head restraint securely
.
Refitting a head restraint
► Insert the head restraint rods into the guides
in the corresponding seat backrest.
►

Push the head restraint fully down.
►


Press the lug
A to release the head restraint
and push it down.
►

Adjust the height of the head restraint.
Never drive with the head restraints
removed; they should be in place and
adjusted for the occupant of the seat.
Front seats
Before moving the seat backwards,
ensure that there is no person or object
that might prevent the full travel of the seat.
There is a risk of trapping or pinching
passengers if present in the rear seats or of
jamming the seat if large objects are placed
on the floor behind the seat.

Ease of use and comfort
Heated seats



The function is active only with the engine
running and when the outside temperature is
below 20°C.
►
Press the button corresponding to the seat.
►


Each press changes the heating level; the
corresponding number of indicator lamps come
on.
►


T
o switch off the heating, press the button
until all of the indicator lamps are off.
The system status is memorised when the
ignition is switched off.
Do not use the function when the seat
is not occupied.
Reduce the heating intensity as soon as
possible.
When the seat and passenger compartment
have reached a satisfactory temperature,
switch the function off; reducing electrical
consumption in turn decreases energy
consumption.
Prolonged use of heated seats is not
recommended for people with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (e.g.
illness,
taking medication).
To keep the heated pad intact and to prevent
a short circuit:
–

Do not place heavy or sharp objects on the
seat.
–


Do not kneel or stand on the seat.
–


Do not spill liquids onto the seat.
–


Never use the heating function if the seat
is damp.
Steering wheel
adjustment


► When stationary , pull the control to release
the steering wheel.
► Adjust the height and reach to suit your
driving position.
►

Push the control to lock the steering wheel.
For safety reasons, these adjustments
must only be carried out with the vehicle
stationary.
Heated steering wheel
(Depending on country of sale)
In cold weather, this function heats the circular
part of the steering wheel.
It can be activated when the outside temperature
is below 20°C.




► With the engine running, press this button to
activate/deactivate the function (confirmed by the
indicator lamp coming on/going out).
The system is automatically deactivated every
time the engine is switched off.

Driving
6Tyre under-inflation detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.
The tyre under-inflation detection cannot, in any circumstances, replace the need
for vigilance on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases energy consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than 6 miles
(10

km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected may not always cause visible deformation 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 all four tyres when cold.
►

If it is not possible to carry out 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).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre
blow-out. This is because analysis of the
values read by the wheel's speed sensors
can take several minutes.
The alert may be delayed at speeds below
25 mph (40 km/h), or when adopting a sporty
driving mode.
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.

Driving
Function statusDisplayComments
ON



"Hold the wheel". If, while correcting the trajectory, the system determines that the correction will not be
enough and that a solid line will be crossed: the driver is warned that \
they must provide
additional trajectory adjustment.
If the steering wheel is not held properly, an audible warning sounds, accompanied by
a message, until the trajectory correction is completed or the driver ha\
s grasped the
steering wheel correctly.
The duration of audible warnings will increase if multiple corrections a\
re performed
in quick succession. The warning will become continuous, persisting until the driver
responds.
Operating limits
The system goes into standby automatically in
the following cases:
–

ESC deactivated or operation triggered.
–


Speed below 40 mph (65
km/h) or greater
than 112 mph (180
km/h).
–

Electrical connection to a trailer
.
–

Use of a"space-saver" spare wheel detected
(as detection is not immediate, deactivation of
the system is recommended).
–


Dynamic driving style detected, pressure on
the brake or accelerator pedal.
–


Driving over lane markings.
–


Activation
of the direction indicators.
–

Crossing the inside line on a bend.
–


Driving on a tight bend.
–


Inactivity by the driver detected during
correction.
–


Narrow lane detected.
The following situations may interfere with the operation of the system or
prevent it from working:
–

Insufficient contrast between the road
surface and the side of the road (e.g. shade).
–


Lane markings worn, hidden (snow
, mud)
or multiple (roadworks, etc.),
–

Close proximity to the vehicle in front (lane
markings may not be detected).
–


Roads that are narrow
, winding.
Risk of undesirable operation
The system should be deactivated in the
following situations:
–
When changing a wheel or working near a
wheel.
–


T
owing or with a bicycle carrier on a towing
device, especially with trailer not plugged in or
not approved. –

Road in poor condition, unstable or with very
poor grip (risk of aquaplaning, snow
, ice).
–
Adverse weather conditions.
–

Driving on racing circuits.
–

Driving on a rolling road.
Deactivation/Activation



► Press and hold this button to deactivate or
press briefly to reactivate the system at any time.
