ADAPTIVE CRUISE CONTROL (1/8)

The adaptive cruise control is a func-

tion which gives you the option, when

traffic conditions permit (large free-flow-

ing road or motorway), of maintaining

a chosen speed, known as the cruising

speed, while keeping a safe distance

from the vehicle in front in the same

lane.

1

The function can be adjusted from

31 mph (50 km/h) to 99.2 mph

(160 km/h).

This function is an addi-

tional driving aid. The func-

tion does not take the place

of the driver.

The radar-camera has a range of

around 120 metres.

Note:

– the driver should take account of the

maximum legally permissible speed

in the country where the vehicle is

travelling;

– the adaptive cruise control can brake

the vehicle up to a third of the brak-

ing capacity. Depending on the situ-

ation, the driver may need to brake

harder.

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).

Location of the radar-

camera 1

Make sure the windscreen is not ob-

scured (dirt, mud, snow, condensation

etc.).

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.

On equipped vehicles, some infor-

mation is given on the head-up dis-

play.

Varying the following

distance

You can vary the following distance

from the vehicle in front at any time by

pressing switch 6 repeatedly.

Once a cruising speed is memorised

and the cruise control function is active,

you may lift your foot off the accelera-

tor pedal.

If a following distance is stored and a

vehicle travelling slower than yours is

detected by the system in your lane,

your vehicle will brake (with the brake

lights on) and adapt its speed to that of

the vehicle in front, respecting the fol-

lowing distance selected previously.

Horizontal following bars will be dis-

played on the instrument panel, indicat-

ing the following distance selected:

– one bar for a short distance (cor-

responding to a following time of

around one second);

– two bars for a medium distance;

– three bars for a long distance (cor-

responding to a following time of

around two seconds).

Overtaking

If your speed is lower than the cruise

control and you wish to perform an

overtaking manoeuvre, activating the

direction indicator will provide acceler-

ation enabling the overtaking manoeu-

vre.

Adjusting the cruising speed

The cruising speed can be changed by

pressing the switch 2 repeatedly:

Choosing the distance should depend

on the traffic, the laws in your country,

and on the weather conditions.

If a vehicle is detected by the system in

your lane, an outline A of a vehicle will

appear above the following bars.

– side a (+) to increase the speed;

– side b (-) to reduce the speed.

Please note that you must

keep your feet close to the

pedals in order to react in

an emergency.

Putting the function on

Returning to the cruising speed

If a speed is stored, it can be recalled,

once you are sure that the road con-

ditions are suitable (traffic, road sur-

face, weather conditions, etc.). Press

switch 3 (R) if the vehicle speed is

above around 31 mph (50 km/h).

The function is set to standby if:

– you press switch 4 (O);

– you depress the brake pedal;

– you depress the clutch pedal;

– you use the gear lever;

When the stored speed is recalled,

activation of the cruise control is con-

firmed by the illumination of the cruis-

ing speed in green, along with the mes-

sage “Adaptive cruise ctrl”.

– the engine speed is too low or too

high;

4

– the vehicle speed is lower than

25 mph (40 km/h) or over 105 mph

(170 km/h) approximately;

When the cruise control is set to

standby, pressing switch 2 side a (+)

reactivates the cruise control function

without taking into account the stored

speed – it is the speed at which the

vehicle is moving that is taken into ac-

count.

– certain driver correction devices and

aids are triggered (ABS, ESC, etc.)

Exceeding the cruising speed

The cruising speed may be exceeded

at any time by depressing the accelera-

tor pedal.

When exceeding this speed, the cruis-

ing speed and the following bars are

shown in red, and the cruising speed

flashes on the instrument panel: the

distance control function is no longer

active.

Then, release the accelerator: cruise

and distance control will automatically

reactivate unless the function has been

set to standby.

In the latter three cases, the message

“Adaptive cruise ct disconnected” is

displayed on the instrument panel when

the function is set to standby.

Note: if the speed previously stored is

much higher than the current speed,

the vehicle will accelerate to reach this

threshold.

Standby is confirmed by the display of

the cruising speed in grey and the mes-

sage “Adaptive cruise ctrl”.

ADAPTIVE CRUISE CONTROL (5/8)

Under certain conditions (coming up

behind a vehicle moving more slowly,

rapid change of lane of vehicles in front

etc.), the system may not have time to

respond and may emit a beep along-

side the alert B when the situation

requires the driver’s attention, or the

alert C when the situation requires im-

mediate action from the driver.

B

React accordingly and perform the ap-

propriate manoeuvres.

C

Putting the cruise control

on standby or switching it

off does not cause a rapid

reduction in speed: you

must brake by depressing the brake

pedal.

2.74

ADAPTIVE CRUISE CONTROL (6/8)

Operating faults

When the system detects an operating

fault the message “Check cruise con-

trol” appears on the instrument panel.

There are two possibilities:

– the system is temporarily disrupted

(for example: radar camera obscured

by dirt, mud, snow etc.). In this case,

park the vehicle and switch off the

engine. Clean the detection zone of

the radar-camera. 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

Switching off the function

The cruise control function is deacti-

vated when you press switch 5 on the

side. In this case, the speed is no



longer stored. The green

indicator



light and the message “Adaptive cruise

ctrl” on the instrument panel go out to

confirm that the function is deactivated.

2.75

ADAPTIVE CRUISE CONTROL (7/8)

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, regardless of the system indications.

The system should under no circumstances be taken to be an obstacle detector or an anti-collision system.

System servicing/repairs

– In the event of an impact, the radar-camera alignment may be changed, and its operation may consequently be affected.

Deactivate the function and consult an authorised dealer.

– Any work in the area where the radar-camera is located (repairs, replacements, windscreen modifications etc.) must be car-

ried out by a qualified professional.

Only an authorised dealer is qualified to service the system.

Deactivating the function

You must disable the function if:

– the brake lights are not functioning;

– the area of the radar-camera has been damaged (on the windscreen side or the interior rear-view mirror side);

– 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 windscreen is cracked or distorted (do not carry out windscreen repairs in this area; have it changed by an Authorised

Dealer);

– the vehicle is travelling on a slippery road or in poor weather conditions (fog, snow, rain, side winds etc.).

In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.

2.76

ADAPTIVE CRUISE CONTROL (8/8)

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 radar-camera should be kept clean and free of any modifications in order 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 entered the detection zone. Sudden or late braking may

then take place.

– When entering a bend or curve, the radar-camera may temporarily no longer detect the vehicle in front, and this may lead

to acceleration.

– 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.

– A slower vehicle with a wide difference in speed may not be taken into account by the system.

– The system is deactivated below around 25 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.

System disturbance

Some conditions can disturb or damage the operation of the system, such as:

– a complex environment (metal bridge, tunnel etc.) ;

– poor weather conditions (snow, hail, black ice etc.);

– poor visibility (night, fog etc.);

– poor contrast between objects;

– being dazzled (glaring sun, lights of vehicles travelling in the opposite direction etc.).

Risk of unwanted braking or acceleration.
