Driving  
– Vehicles crossing your lane.  
– When a vehicle cuts in sharply between your  
vehicle and the one in front.  
If this warning lamp comes on,  
accompanied by an alert message and an  
audible signal, this confirms the malfunction.  
Have the system checked by a dealer or a  
qualified workshop.  
– Vehicles driving in the opposite direction.  
Situations in which the driver must pause the  
cruise control system:  
Pay particular attention:  
– When motorcycles are present and  
when there are vehicles staggered across the  
traffic lane.  
– When entering a tunnel or crossing a bridge.  
Active Lane Keeping  
Assist  
Refer to the General recommendations on the use  
of driving and manoeuvring aids.  
If any of the following malfunctions  
occurs, do not use the system:  
– Following an impact on the windscreen close  
to the camera or on the front bumper (versions  
with radar).  
– Vehicles in a tight bend.  
– When approaching a roundabout.  
– Brake lamps not working.  
If the vehicle has undergone any of the  
following modifications, do not use the  
system:  
– Carrying long objects on roof bars.  
– Towing.  
– Front end of the vehicle modified (for  
example by adding long-range headlamps or  
painting the front bumper).  
Using a camera located at the top of the  
windscreen, the system identifies lane markings  
and steers the vehicle inside this lane to keep it in  
the lateral position chosen by the driver.  
This function is primarily suitable for driving on  
motorways and main roads.  
– When following a narrow vehicle.  
Reactivate cruise control when conditions permit.  
Situations in which the driver is prompted to  
immediately resume control:  
– Excessively sharp deceleration by the vehicle in  
front of you.  
Conditions for operation

for a while, they can deactivate it by pressing the  
button again.

state of the road surface require their  
Activation/Deactivation  
intervention, by moving the steering wheel to  
temporarily suspend system operation. Any  
action on the brake pedal that results in cruise  
control being paused will also cause the  
system to be paused.  
The system status is saved when the  
ignition is switched off.  
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.  
Cruise control  
►ꢀ With the Adaptive Cruise Control with Stop &  
Go function activated, press this button.  
The action is confirmed by:  
– The indicator lamp in the button lighting up  
green.  
– The following symbol being displayed on the  
instrument panel.  
The colour of the symbol on the instrument panel  
depends on the operating status of the system:  
(grey colour)  
One or more operating conditions is not  
met; the system is paused.  
(green colour)  
All operating conditions are met; the  
system is active.  
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.  
If the function is suspended due to the  
prolonged release of the force holding the  
steering wheel, you must reactivate it by  
pressing the button again.  
The driver can feel movements in the steering  
wheel.  
Automatic pause  
The driver can change the position of the vehicle  
at any time, by turning the steering wheel, which  
suspends the function. The driver positions the  
vehicle where they wish to in the lane. When  
the driver feels that the vehicle’s position is  
appropriate, they maintain it until the function  
is reactivated. The system regains control by  
regulating on the new defined position.  
– Triggering of the ESC.  
– Prolonged failure to detect one of the lane  
limit markings. In this case, the active lane  
departure warning function can take over, and the  
system will reactivate itself once the operating  
conditions are again met.

In response to action by the driver: suspension  
– Activation of the direction indicators.  
– Travelling outside the lane limits.  
– Too tight a grip on the steering wheel or  
dynamic action on the steering wheel.  
For vehicles equipped with a head-up  
display, the information is projected onto  
the blade.  
Pausing/Suspending the  
system  
– Action on the brake pedal (resulting in a pause  
until cruise control is reactivated) or accelerator  
The driver must act promptly if they  
believe that the traffic conditions or the
