Adaptive cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and the
Cruise control - particular
recommendations.
This system automatically maintains the vehicle
speed at a value set by the driver (speed
setting), while respecting a safety distance from
the vehicle in front (target vehicle) previously set
by the driver. The system automatically manages
the acceleration and deceleration of the vehicle.
With the Stop function, the system manages
braking until the vehicle comes to a complete
stop.
With the Stop & Go function, the system
manages braking until the vehicle comes to a
complete stop and restarts the vehicle.
The brake lamps come on if the vehicle
is slowed down by the system.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
To do this, the system uses a camera fitted at the
top of the windscreen and a radar fitted in the
front bumper.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
If the driver activates the direction
indicator to overtake a slower vehicle,
cruise control may temporarily reduce the
distance to the target vehicle to facilitate
overtaking, without exceeding the speed
setting.
