Peugeot 308: Lane positioning assist

For more information, refer to the General recommendations on the use of driving and manoeuvring aids.

The system identifies the edges of the traffic lane and steers the vehicle to keep it inside this lane and maintain the lateral position chosen by the driver.

To do this, the system uses a camera placed on the upper part of the windscreen.

This system is particularly suited to driving on motorways and main roads.

Activation/Deactivation

The Lane positioning assist system is automatically activated, after selecting Drive Assist Plus mode.

For more information on the Drive Assist Plus system, refer to the corresponding section.

The selection is confirmed by the display of the symbols on the instrument panel, representing the steering wheel and the side lines.

The colour of the symbols depends on the operating state of the system:

(grey)

One or more operating conditions is not met; the system is paused.

(green)

All operating conditions are met; the system is active.

(orange)

System malfunction.

If the driver no longer wishes to use the system for some time, they can deactivate it by pressing the ASSIST button again (confirmed by the Driving aids mini-view disappearing from the instrument panel).

The system status is saved when the ignition is switched off.

Operating conditions

• Adaptive cruise control active.
• ESC system operational.
• ASR system activated.
• No trailer detected.
• No 'space-saver' spare wheel in use.
• Vehicle not subject to strong lateral acceleration.
• Direction indicators off upon activation of the system.

Regulation

The driver must hold the steering wheel properly. When regulation is activated, the symbols are displayed in green: with small steering inputs, the system steers 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.

The driver can feel movements in the steering wheel.

At any time, the driver can change the position of the vehicle by intervening on the steering wheel and maintaining the position until the system has taken it into account. If the chosen position is too off-centre, an automatic re-centering manoeuvre can occur. The system adjusts to the newly defined position.

Pausing/Suspending the system

The driver must act promptly if they believe that the traffic conditions or the state of the road surface require their intervention, by moving the steering wheel to temporarily suspend system operation. Any action on the brake pedal that causes the Adaptive cruise control system to be paused will also cause the system to be paused.

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.

If the function is suspended due to the prolonged release of the force holding the steering wheel, the system must be reactivated by pressing the ASSIST button again.

Automatic suspension

Suspension of the system is accompanied by a specific audible signal.

- Triggering of the ESC system.

- Insufficient lane detection. In this case, the Lane keeping assist function can take over, and the system will reactivate itself once the operating conditions are met again.

Paused by the driver

- Travelling outside the lane limits.

- Too tight a grip on the steering wheel or dynamic action on the steering wheel.

- Action on the brake pedal (resulting in a pause until cruise control is reactivated) or accelerator pedal (suspension for as long as the pedal is depressed).

- Pausing of the Adaptive cruise control system.

- Deactivation of the ASR system.

Driving situations and related alerts

The tables below describe the displays associated with the main driving situations. The actual order of display of these alerts may be different.

Operating limits

The system may issue an alert when the vehicle is travelling on a long, straight road with smooth road surface even if the driver thinks they are holding the steering wheel correctly.

The system may not operate or may produce unsuitable corrections to the steering in the following situations:

- Wearing thick gloves (with Drive Assist 2.0).

- Poor visibility (insufficient road lighting, snowfall, rain, fog).

- Dazzle (headlamps of an oncoming vehicle, low sun, reflections on a wet road surface, leaving a tunnel, alternating light and shade).

- Windscreen area in front of the camera dirty, misted up, frost-covered, snow-covered, damaged or covered by a sticker.

- Lane markings eroded, partially hidden (snow, mud) or multiple (roadworks, surface joints).

- Travelling in a tight bend.

- Winding roads.

- Road surface repairs.

Risk of undesirable operation

The system should be deactivated in the following situations:

- When changing a wheel or working near a wheel.

- Towing or with a bicycle carrier on a towing device, especially with trailer not plugged in or not approved.

- Adverse weather conditions.

- Road with low grip (risk of aquaplaning, snow, ice).

- Road works and toll areas.

- Driving on racing circuits.

- Driving on a rolling road.

Malfunction

In the event of a malfunction, the Service warning lamp comes on and this (orange) symbol appears on the instrument panel, accompanied by the display of a message and an audible signal.

Have it checked by a PEUGEOT dealer or a qualified workshop.
