SAFE DISTANCE ALERT (2/2)
The measurement is dis-
played for information only:
the system performs no
action on the vehicle.
This function is not designed for use
in urban conditions or for a dynamic
driving style (sudden cornering, ac-
celeration, braking, etc.), but rather
for stable driving conditions.
The function does not interact with
the braking system.
The sensor area should be kept
clean and free of any modifications
in order to ensure the proper opera-
tion of the system.
Any work in the area where the
radar is located (repairs, replace-
ments, touching up of paintwork)
must be carried out by a qualified
professional.
– C (orange): the time interval falls
between around 1 and 2 seconds (in-
sufficient distance between the two
vehicles);
– D (red): the time interval is less than
or equal to around one second (very
insufficient distance between the two
vehicles).
If the interval between the two vehicles
is less than around 0.5 seconds, war-
ning light 4 will flash on the instrument
panel. Under certain conditions, the
time interval may not be displayed:
– while cornering;
– when changing lane;
– if the vehicle in front is sufficiently far or outside the range of the sensor.
This function is essential if adaptive
cruise control is activated.
On equipped vehicles, some infor-
mation is given on the head-up dis-
play.

Operation
Upon activating the function, indicator 4
notifies the driver of the distance sepa-
rating them from the vehicle in front.
– A (grey): function not operational;
– A (green): no vehicle detected;
– B (green): the time interval is greater
than or equal to around two seconds
(distance between the two vehicles
adapted to your speed);

2.61
ADAPTIVE CRUISE CONTROL (1/7)
When traffic conditions permit (large
free-flowing road or motorway), the
adaptive cruise control gives you the
option of maintaining a chosen speed,
known as the cruising speed, adjust-
able from 31 mph to 93 mph (50 and
150 km/h), or 68.2 mph (110 km/h) de-
pending on the vehicle, while keeping
a following distance from the vehicle in
front in the same lane.
The sensor has a range of 120 metres.
Note: The driver should take into ac-
count the maximum speed limit in the
country where they are driving.
Note: the adaptive cruise control can
brake the vehicle up to a third of the
braking capacity. Depending on the
situation, the driver may need to brake
harder.
This function is an additio-
nal driving aid. This function
does not take the place of
the driver.
Therefore, it can under no circum-
stances replace the driver’s respon-
sibility to respect speed limits and to
be vigilant (the driver must always
be ready to brake).
The adaptive cruise control should
not be used in heavy traffic, on
winding or slippery roads (black ice,
aquaplaning, gravel) and during bad
weather (fog, rain, side winds etc.).
There is a risk of accidents.
Sensor location
Make sure that the sensor 1 is not ob-
scured (by dirt, mud, snow, etc.).

On equipped vehicles, some infor-
mation is given on the head-up dis-
play.

2.66
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
 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

2.67
ADAPTIVE CRUISE CONTROL (7/7)
Limitation of the system operation
– A vehicle travelling in the opposite direction will not trigger any alert\
or any action on the system operation.
– The sensor area should be kept clean and free of any modifications in or\
der to ensure the proper operation of the
system.
– Fixed obstacles (stationary vehicles, traffic jams, toll booths etc.) or objects travelling at low speed or of a \
small size ( motor-
bikes, bicycles, pedestrians etc.) may not be detected by the system.
– A vehicle entering the same lane will only be detected once it has entere\
d the detection zone. Sudden or late braking may then take place.
– When entering a bend or curve, the sensor may temporarily no longer dete\
ct the vehicle in front, and this may lead to acce- leration.
– When exiting a curve, the detection of the vehicle in front may be affected or delayed. Sudden or late braking may then take place.
– A slower vehicle travelling in an adjacent lane may be detected and cause\
a slowing down if one of the two vehicles is trav- elling too close to the lane of the other.
– The system is deactivated below around 20 mph (40 km/h). Drivers must \
react accordingly.
– Sudden changes in situation are not instantly taken into account by the \
system. Drivers must remain vigilant at all times and
under all circumstances.
Deactivating the function
You must disable the function if:
– the brake lights are not functioning;
– the front of the vehicle has undergone an impact or been damaged;
– the vehicle is being towed (breakdowns);
– traffic is heavy;
– the vehicle is travelling in a tunnel;
– the vehicle is travelling on a windy road;
– the vehicle is travelling on a slippery road or in poor weather conditio\
ns (fog, snow, rain, side winds etc.).
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.

2.68
PARKING DISTANCE CONTROL (1/5)
Operating principle
Ultrasonic sensors in the rear bumper
measure the distance between the ve-
hicle and an obstacle.
This measurement is indicated by
beeps which become more frequent the
closer you come to the obstacle, until
they become a continuous beep when
the vehicle is approximately 20 to
30 centimetres from the obstacle.
The system detects obstacles to the
front, the rear and the sides of the ve-
hicle.
The parking distance control system
is only activated when the vehicle is
driven at a speed below approximately
6 mph (10 km/h).
The parking distance control system
does not take into account towing and
load carrying systems etc.
This function is an addi-
tional aid that indicates the
distance between the vehi-
cle and an obstacle whilst
reversing, using sound signals.
Under no circumstances should it
replace the driver’s care or respon-
sibility whilst reversing.
The driver should always be ready
for sudden incidents while driv-
ing: always ensure that there are
no small, narrow moving obstacles
(such as a child, animal, pushchair,
bicycle, stone, post etc.) in the blind
spot when manoeuvring.
Special features
Ensure that the ultrasonic sensors indi-
cated by arrows 1 are not obscured (by
dirt, mud, snow, etc.).

2.72
Automatic deactivation of the
parking distance control
The system deactivates:
– when the vehicle speed is above ap-proximately 6 mph (10 km/h);
– depending on the model, when the vehicle is stationary for more than
approximately 5 seconds and an ob-
stacle is detected (such as when in a
traffic jam, etc.);
– when the vehicle is in neutral for manual gearboxes, or in position N
or P for automatic gearboxes.
PARKING DISTANCE CONTROL (5/5)
Operating faults
When the system detects an operating
fault, a beep sounds for approximately
3 seconds each time reverse gear is se-
lected and is accompanied by the mes-
sage “Check parking sensor” shown on
the instrument panel. Please consult an
authorised dealer.

2.75
ASSISTED PARKING (1/4)
This function assists with parking ma-
noeuvres.
Take your hands off the steering wheel.
You only control the pedals and the
gear lever.
You can retake control at any time by
operating the steering wheel.Switching on
With the vehicle at a standstill or driving
at less than approximately 18.6 mph
(30 km/h), press switch 1. The warn-
ing light integrated on switch 1 lights up

ASSISTED PARKING (3/4)
Your speed should not exceed around
4 mph (7 km/h).
Once in position to exit the space, the
system will notify you of the end of the
manoeuvre.
Once the warning light
 on the
instrument panel goes off and a beep
sounds, the manoeuvre has been com-
pleted.
Suspending the manoeuvreThe manoeuvre is suspended in the fol-
lowing circumstances:
– you take control of the wheel;
– a door or the boot is opened;
– the vehicle is at a standstill for too long;
– an obstacle in the direction of move- ment prevents the manoeuvre from
being completed;
– the engine will stop.
Once the warning light
 on the
instrument panel goes off and a beep
sounds, the manoeuvre has been sus-
pended. Then to resume the manoeu-
vre, press and hold the system activa-
tion switch. In this case, the reason for suspending
the manoeuvre will be displayed on the
multifunction screen.
Make sure:
– you have released the steering wheel
and;
– that all doors and the boot are closed, and;
– that no obstacles are in the way of the direction of movement, and;
– that the engine is started.
Cancelling the manoeuvre
The manoeuvre can be stopped in the
following cases:
– by pressing the system activation switch;
– the vehicle speed has exceeded 4 mph (7 km/h);
– You have performed more than ten forwards/backwards movements in
one manoeuvre;
– the parking distance control sensors are dirty or blocked;
– the vehicle wheels have skidded.
Once the warning light
 on the
instrument panel goes off and a beep
sounds, the manoeuvre has been com-
pleted.
Exiting a parallel parking space
– Select “exit parallel parking space” mode;
– activate the direction indicator on the side you wish to go out of;
– press and hold switch 1 (around
2 seconds).
