Peugeot 308: Lane keeping assist

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

The system corrects the vehicle's trajectory by alerting the driver as soon as it detects a risk of involuntary lane departure or crossing of a verge or hard shoulder (depending on version).

To do this, the system uses a camera, placed on the upper part of the windscreen, identifying the lane markings on the ground and the side of the road (depending on version).

This system is particularly useful on motorways and main roads.

• Operating conditions
• Operating limits

Operating conditions

- Vehicle speed between 43 and 112 mph (70 and 180 km/h).

- Road marked with a central dividing line.

- Steering wheel held with both hands.

- Direction indicators off upon activation of the system.

- ESC system activated and operational.

The system helps the driver only if there is a risk of the vehicle unintentionally wandering from the lane it is being driven in. It does not manage the safe driving distance, vehicle speed or braking.

The driver must hold the steering wheel with both hands so that they can maintain control when the conditions no longer allow the system to intervene (e.g. in the event that the central dividing line marking on the road surface disappears).

Operation

As soon as the system identifies a risk of involuntarily crossing one of the lane markings detected on the ground or a lane boundary (e.g. grass verge), it performs the trajectory correction necessary to restore the vehicle to its original lane.

The driver will notice a turning movement of the steering wheel.

This warning lamp flashes during trajectory correction.

The driver can prevent the correction by firmly holding the steering wheel (e.g. during an emergency manoeuvre).

The correction is interrupted immediately if the direction indicators are operated.

While the direction indicators are activated and for a few seconds after switching them off, the system considers that a change of trajectory is intentional and no correction is triggered during this period.

Driving situations and related alerts

The table below describes the alerts and messages displayed in different driving situations.

The actual order of display of these alerts may be different.

Operating limits

The system goes into standby automatically in the following cases:

- ESC deactivated or operation triggered.

- Speed below 40 mph (65 km/h) or greater than 112 mph (180 km/h).

- Electrical connection to a trailer.

- Use of a "space-saver" spare wheel detected (as detection is not immediate, deactivation of the system is recommended).

- Dynamic driving style detected, pressure on the brake or accelerator pedal.

- Driving over lane markings.

- Activation of the direction indicators.

- Crossing the inside line on a bend.

- Driving on a tight bend.

- Inactivity by the driver detected during correction.

- Narrow lane detected.

The following situations may interfere with the operation of the system or prevent it from working:

- Insufficient contrast between the road surface and the verge or hard shoulder (e.g. shade).

- Lane markings worn, hidden (e.g. snow, mud) or multiple (e.g. roadworks).

- Close proximity to the vehicle in front (lane markings may not be detected).

- Roads that are narrow, winding.

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.

- Road in poor condition, unstable or with very poor grip (risk of aquaplaning, snow, ice).

- Adverse weather conditions.

- Driving on racing circuits.

- Driving on a rolling road.

Deactivation/Activation

By default, the system is automatically activated at every engine start

It is configured in the ADAS touch screen application.

or

Direct access to the Shortcuts for driving aids.

Deactivation is confirmed by the illumination of this indicator lamp on the instrument panel.

Malfunction

In the event of a malfunction, these warning lamps light up 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.

This warning lamp lights up on the instrument panel with the message "Driving Assistance Sensor blind: Clean sensor, see User Manual" if the sensor is masked.

This is a normal behavior, which does not request the support of a qualified workshop.

In this case, stop the vehicle and verify if the front camera is covered by dirt, mud, sand, snow, ice or anything preventing the sensing.

The system is operational again after the detection field has been cleaned.
