setting as soon as the vehicle speed reaches the

desired level (green).

► Pressing button 2-I I> temporarily pauses the

function.

121

Driving

► Pressing 2-I I>, 3 or 4-OK again will

reactivate cruise control (green).

When the function is activated, the speed

setting value can be changed using the speed

suggested by the Road signs recognition

function displayed on the instrument panel:

– When passing the sign:

► Press 4-OK to save the suggested speed.

This value is then immediately shown as the new

speed setting on the instrument panel.

– After passing the sign:

Adaptive cruise control with Stop&Go function in

conjunction with the Lane Positioning Assist.

These two functions must be activated and in

operation.

This system is especially suitable for driving on

motorways and main roads.

For more information on Adaptive cruise

control and Lane Positioning Assist, refer to

the corresponding sections.

Cruise control operation is also

temporarily interrupted (pause):

– by pressing the brake pedal.

– automatically, if the electronic stability

control (ESC) system is triggered.

– by shifting to neutral or engaging reverse

gear.

– by depressing the clutch pedal for more

than 5 seconds.

– by using the electric parking brake.

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

or vehicles in the surroundings may not be

properly seen or may be poorly interpreted by

the camera and radar, resulting in an

unexpected change in direction, a lack of

steering correction and/or inappropriate

management of acceleration or braking.

Modifying the speed setting

The cruise control must be active.

To change the speed setting using the vehicle’s

current speed:

► For steps of +/- 1 mph (1 km/h),

make successive short presses upwards/

downwards on 3 to increase/decrease.

► For steps of +/- 5 mph (5 km/h), press and

hold upwards/downwards on 3 to increase/

decrease.

Oﬀ

► Press 1: the cruise control information display

disappears.

Malfunction

In the event of a malfunction, dashes are

displayed ﬂashing and then ﬁxed (orange)

instead of the speed setting.

Have it checked by a PEUGEOT dealer or a

qualiﬁed workshop.

Selecting/Deselecting the

system

Prolonged pressing and holding

upwards/downwards on 3 causes a very

rapid change in vehicle speed.

Drive Assist Plus

Only available on versions with automatic

gearbox.

This system automatically adjusts the speed and

corrects the trajectory of the vehicle, using the

As a precaution, we recommend setting

a cruise speed fairly close to the current

speed of your vehicle, to avoid any sudden

acceleration or deceleration of the vehicle.

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 a manual gearbox, the system slows the

vehicle down as far as a speed of 19 mph (30

km/h).

With the Stop & Go function, the system

manages braking until the vehicle comes to a

complete stop and restarts the vehicle.

The colour of the symbols, representing the

With an automatic 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 2-I I> or the accelerator pedal to

move oﬀ.

Modifying the speed setting

To change the speed setting using the vehicle’s
