sharp acceleration, the speed limiter will  
not be able to prevent the vehicle from  
exceeding the speed setting.  
In the interest of public safety, only use cruise  
control if the traffic conditions enable vehicles  
to drive at a steady speed and maintain an  
adequate safety distance.  
– On winding or steep roads.  
– On slippery or flooded roads.  
– In poor weather conditions.  
– In the event of restricted visibility for the  
driver.  
If necessary, apply the brakes to control your  
vehicle’s speed.  
Remain vigilant while cruise control is  
activated. If you press and hold one of the  
speed setting modification buttons, your  
vehicle may change speed very abruptly.  
When descending a steep hill, the cruise  
control system cannot prevent the vehicle from  
exceeding the set speed. Brake if necessary to  
control the vehicle speed.  
When the vehicle speed returns to the speed  
setting level, the speed limiter operates again: the  
speed setting display becomes fixed again.  
– Driving on a speed circuit.  
– Driving on a rolling road.  
– When using a ‘space-saver’ type spare  
wheel.

Programmable cruise  
control  
Exceeding the programmed speed setting  
You can temporarily exceed the speed  
setting by pressing the accelerator pedal (the  
programmed speed flashes).  
In the event of a malfunction, dashes are  
displayed flashing and then fixed instead of the  
speed setting.  
For more information, refer to the General  
recommendations on the use of driving  
and manoeuvring aids and the Cruise control  
- particular recommendations.  
To return to the speed setting, release the  
accelerator pedal (when the set speed is  
reached again, the displayed speed stops  
flashing).  
Have it checked by a dealer or a qualified  
workshop.  
This system automatically maintains the  
vehicle’s speed at the value programmed  
by the driver (speed setting), without the use of  
the accelerator pedal.  
Cruise control - Specific  
recommendations  
Operating limits  
Cruise control is switched on manually.  
It requires a minimum vehicle speed of 25 mph  
(40 km/h).  
Never use the system in the following  
situations:  
The cruise control function does not  
guarantee compliance with the maximum  
authorised speed and the safety distance  
– In an urban area with the risk of pedestrians  
crossing the road.

steering correction and/or inappropriate  
management of acceleration or braking.  
Primarily designed for driving on main  
roads and motorways, this system only  
works with moving vehicles driving in the same  
direction as your vehicle.

To do this, the system uses a camera fitted at the  
top of the windscreen and a radar fitted in the  
front bumper.  
In the event of a malfunction, dashes are

Adaptive cruise control  
Have it checked by a dealer or a qualified  
workshop.  
For more information, refer to the General  
recommendations on the use of driving  
and manoeuvring aids and the Cruise control  
- particular recommendations.  
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.  
DS DRIVE ASSIST  
This system automatically adjusts the speed  
and corrects the trajectory of the vehicle, using  
Adaptive cruise control with Stop&Go function in  
conjunction with Lane Positioning Assist.  
These two functions must be activated and in  
operation.  
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 & Go function, the system manages  
braking until the vehicle comes to a complete stop  
and restarts the vehicle.  
For more information on Adaptive cruise  
control and Lane Positioning Assist, refer to the  
corresponding sections.  
The system assists the driver by acting on  
the steering, acceleration and braking  
within the physical limits and capacities of the  
vehicle. Certain road infrastructure elements
