Driving06
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. When
the driver feels that the vehicle’s position is
appropriate, whilst keeping hands on the steering
wheel, they must release the pressure to let the
system resume control of the steering, but the
vehicle will not be automatically centred within
the lane.
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
intervention on the brake pedal that causes
the Adaptive cruise control to pause will also
cause the system to pause.
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, the function must be
reactivated 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 Lane keeping
assist function can take over, and the system will
reactivate itself once the operating conditions are
met again.
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.
–

Action on the brak
e pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).
–

Pausing o
f Adaptive cruise control.
–

Deactiv
ation of the ASR.

Messages
Driving situations
"Activate cruise control to use lane positioning assist" Activation of lane positioning assist while cruise control is not active. "Conditions unsuitable - Awaiting activation" Activation of lane positioning assist while not all conditions are met.
"Keep your hands on the steering wheel" Prolonged driving without holding the steering wheel, holding it improperly or
without applying any force.
"Hold the steering wheel" Actual or imminent loss of lane positioning assist.
"Take back control" Simultaneous loss of cruise control and lane positioning assist.
Operating limits
The system may issue an alert when the
vehicle is travelling on a long, straight
road with smooth road surface even if the
driver thinks they are holding the steering
wheel correctly.
The system may not operate or may produce
unsuitable corrections to the steering in the
following situations:
–

Poor visibility (insufficien
t road lighting,
snowfall, rain, fog). –

Dazzle (headlamp
s of an oncoming vehicle, low
sun, reflections on a wet road surface, leaving a
tunnel, alternating light and shade).
– Windscreen area in fron t of the camera dirty,
misted up, frost-covered, snow-covered, damaged
or covered by a sticker.
–

Lane markings eroded, partially hidden (
snow,
mud) or multiple (roadworks, surface joints).
–

Tra
velling in a tight bend.
–

Winding roads.
–


Pre
sence of a tarmac joint on the road.
Risk of undesirable operation
The system should be deactivated in the
following situations:
–

D

riving with a "space-saver" type spare
wheel.
–

When t
owing or with a bicycle carrier
attached to a towing device, particularly when
a trailer is not connected or the trailer is not an
approved type.
–

Adv
erse weather conditions.
–

D

riving on slippery road surfaces (risk of
aquaplaning, snow, ice).
–

In roadw
orks or toll booth areas.
–

D

riving on racing circuits.

Lane keeping assist
For more information, refer to the General
recommendations on the use of driving
and manoeuvring aids.
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on motorways
and main roads.


Operating conditions
– Vehicle speed between 43 and 112 mph (70 and
180 km/h).
–

R
oad marked with a central dividing line.
–

St
eering wheel held with both hands.
–

Direction indic
ators off upon activation of the
system.
–

ESC s
ystem activated and operational.
The system helps the driver only if there is
a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
The driver must hold the steering wheel with
both hands so that they can maintain control
when the conditions no longer allow the
system to intervene (e.g. in the event that
the central dividing line marking on the road
surface disappears).
Operation
As soon as the system identifies a risk of
involuntarily crossing one of the lane markings
detected on the ground or a lane boundary
(e.g. grass verge), it performs the trajectory
correction necessary to restore the vehicle to its
original lane.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction.
The driver can prevent the correction by
firmly holding the steering wheel
(e.g. during an emergency manoeuvre).
The correction is interrupted immediately if
the direction indicators are operated.
While the direction indicators are activated and
for a few seconds after switching them off, the
system considers that a change of trajectory is intentional and no correction is triggered during
this period.
