LANE DEPARTURE WARNING (1/3)
This system notifies the driver when
they accidentally cross a continuous or
broken line.
This function uses a camera attached
to the windscreen, behind the rear-view
mirror.
This function is an additional driving aid. This function is not under any
circumstances intended to replace the due care and attention of the
driver, who should at all times be in control of the vehicle.
System servicing/repairs
– In the event of an impact, the camera alignment may be changed, and its \
op- eration may consequently be affected. Deactivate the function, then consult an
authorised dealer.
– Any work in the area where the camera is located (repairs, replacements\
, wind- screen modifications etc.) must be carried out by a qualified professio\
nal.
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such \
as:
– a complex environment (tunnel etc.);
– poor weather conditions (snow, hail, black ice etc.);
– poor visibility (night, fog etc.);
– road markings which are worn, lacking in contrast or very widely spaced \
from one another (lines partially erased etc);
– being dazzled (glaring sun, lights of vehicles travelling in the opposi\
te direction etc.);
– the road is narrow, winding or undulating (tight bends etc.);
– closely following a vehicle travelling in the same lane.
Risk of false alarms or absence of warnings

BLIND SPOT WARNING (3/4)
Operation
This function will indicate:
– when the vehicle speed is between approximately 30 km/h (19 mph) and
140 km/h (87 mph);
– when another vehicle is in the blind spot area and travelling in the same
direction as your vehicle.
If another vehicle is being overtaken,
the indicator 6 will be activated only if
that vehicle remains in the blind spot for
more than one second.
Indicator 6
An indicator light 6 is located on each
door mirror 7.
Note: clean the rear view mirrors 7
regularly so that the indicators 6 can be
seen.
Display B
The function is activated and has not
detected any vehicles.
Display C
First warning: the indicator 6 means
that a vehicle has been detected in the
blind spot.
Display D
When the direction indicator is acti-
vated, the indicator light 6 flashes when
a vehicle is detected in the blind spot on
the side towards which you are about to
steer. If you cancel the direction indica-
tor, the function will return to the initial
warning (display C).

Operating faults
If the system detects a fault, the mes-
sage “Check blind spot alert” is dis-
played on the instrument panel. Consult
an approved dealer.
Note: when the engine is started, the
indicator light 6, display B , flashes
three times. It is normal.
– The system’s detection
range operates according
to a standard lane width. If
you are driving in wide traf-
fic lanes, the system might not
be able to detect a vehicle in the
blind spot.
– The system might be disrupted momentarily if it is exposed to
strong electromagnetic waves
(as beneath high-tension power
lines) or to very poor weather
conditions (heavy rain, snow,
etc.). Remain aware of driving
conditions.
There is a risk of accidents.
BLIND SPOT WARNING (4/4)
Because sensors have
been installed in the bump-
ers, any work (repairs, re-
placements, touching up of
paintwork) must be carried out by a
qualified professional.

ADAPTIVE CRUISE CONTROL (6/7)
This function is an additional driving aid. This function is not under any
circumstances intended to replace the due care and attention of the
driver, who should at all times be in control of the vehicle.
The driver should always adapt their speed to the traffic conditions, re-
gardless of the system indications.
The system should under no circumstances be taken to be an obstacle dete\
ctor
or an anti-collision system.
System servicing/repairs
– In the event of an impact, the sensor alignment may become changed, and \
its operation will consequently be affected. Deactivate the function, then consult
an authorised dealer.
– Any work in the area where the radar is located (repairs, replacements,\
touch- ing up of paintwork) must be carried out by a qualified professional.
System disturbance
In a complex environment (metal bridge, etc.), the system may be affected.
Risk of inadvertent braking.
Operating faults
When the system detects an operating
fault, the
\b warning light lights up
on the instrument panel, with the mes-
sage “Check cruise control”.
There are two possibilities:
– the system is temporarily disrupted (for example: radar obscured by
dirt, mud, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the detection zone of
the radar. When you next start the
engine, the warning light and the
message go out.
– Otherwise, this may be caused by another fault. Consult an approved
dealer

Choice of manoeuvre
The system can perform four types of
manoeuvres:
– parallel parking;
– perpendicular parking;
– angle parking;
– moving out of a parallel parking space.
From the multimedia screen, select the
manoeuvre you wish to perform.
Note: when starting the vehicle, or after
having successfully completed parallel
parking using the system, the default
manoeuvre proposed by the system is
assistance in exiting a parallel parking
space. In other cases, the default ma-
noeuvre can be set from the multimedia
screen.
ASSISTED PARKING (2/4)
Operation
