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.

Malfunction

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

displayed flashing and then fixed instead of the

speed setting.

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

Driving

Switching on cruise control and setting the

speed

Cruise control remains active after

changing gear, regardless of the gearbox

type.

Steering-mounted controls

With an automatic EAT8 gearbox, your speed

must be between 0 and 112 mph (0 and 180 km/h).

►ꢀ Press button 2 or 3: the current speed

becomes the speed setting (minimum 19 mph

(30 km/h)) and cruise control is immediately

activated (green display).

When the driver attempts to reactivate

cruise control, after the function has been

paused, the message "Activation not possible,

unsuitable conditions" is briefly displayed if

reactivation is not possible (safety conditions

not met).

►ꢀ Press 3 to increase or 2 to decrease the speed

setting (steps of 5 mph (km/h) if held pressed).

1. ON (CRUISE position)/OFF

Pressing and holding button 2 or 3 results

in a rapid change in the speed of the

vehicle.

►ꢀ Press 4 or depress the brake pedal. To pause

cruise control, it is also possible to:

To prevent sudden acceleration or

deceleration of the vehicle, select a speed

setting relatively close to the vehicle's current

speed.

Confirmation of vehicle restart after

function)

• shift from mode D to N;

• press the electric parking brake control.

►ꢀ Press 4 to restart cruise control. Cruise control

6. Display and adjustment of the distance

setting to the vehicle in front

With an EAT8 gearbox, following braking that

has brought the vehicle to a complete stop, if the

traffic conditions do not allow the vehicle to begin

moving again within 3 seconds of stopping, press

button 4 or the accelerator pedal to move off.

If the driver takes no action after the vehicle

has been stopped, the electric parking brake is

applied automatically after about 5 minutes.

►ꢀ Press 6 to display the distance setting

Driving

– Vehicles driving in the opposite direction.

Situations where the driver must suspend the

system:

Some vehicles on the road may be poorly

perceived or interpreted by the camera

and/or the radar (e.g. truck), which can lead to

an incorrect evaluation of distances and result

in inappropriate acceleration or braking of the

vehicle.

Malfunction

In the event of a malfunction,

dashes are displayed instead of

the speed setting.

This warning lamp comes on, accompanied

by a message and an audible signal, to

Pay particular attention:

confirm the malfunction.

– When motorcycles are present and

when there are vehicles staggered across the

traffic lane.

Have it checked by a dealer or a qualified

workshop.

– Vehicles in a tight bend.

– When entering a tunnel or crossing a bridge.

– When approaching a roundabout.

Lane positioning assist

If any of the following malfunctions

occurs, do not use the system:

For more information, refer to the General

recommendations on the use of driving

and manoeuvring aids.

– Following an impact on the windscreen close

to the camera or on the front bumper (versions

with radar).

– Brake lamps not working.

– When following a narrow vehicle.

Reactivate the system when conditions allow.

Situations in which the driver is prompted to

immediately resume control:

If the vehicle has undergone any of the

following modifications, do not use the

system:

– Excessively sharp deceleration by the vehicle in

front of you.

– Carrying long objects on roof bars.

– Towing.

The system identifies the limits of the traffic lane

and steers the vehicle inside this lane to maintain

it in the lateral position chosen by the driver.

To do this, the system uses a camera placed on

the upper part of the windscreen.

– Front end of the vehicle modified (for

example by adding long-range headlamps or

painting the front bumper).

– Obstructed radar.

This function is primarily suitable for driving on

motorways and main roads.

– When a vehicle cuts in sharply between your

vehicle and the one in front.
