Get Driving -> Lane keeping assist(LKA) Guide for Peugeot 408 4 Door Second Generation (2022-2026)

Driving

At a first alert level, the driver is warned by

the message "Caution!", accompanied by an

audible signal.

After three first-level alerts, the system triggers

a further alert with the message "Driving at

risk: Take a break", accompanied by a more

pronounced audible signal.

Risk of undesirable operation

The system should be deactivated in the

following situations:

display of a message and an audible

signal.

Have it checked by a PEUGEOT dealer or a

qualified workshop.

► When a "space-saver" spare wheel is fitted.

► When the vehicle is towed.

► Driving on off-road.

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.

► Driving on racing circuits.

In certain driving conditions (poor road

surface or strong winds), the system may

give alerts independent of the driver's level of

vigilance.

Deactivation/Activation

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.

Due to legal requirements, the system can only

be deactivated in the vehicle personalization

until the next time the ignition is reactivated.

The following situations may interfere with

the operation of the system or prevent it

from working:

The settings are changed via the

ADAS touch screen application.

► Lane positioning assist is active.

► poor visibility (e.g. inadequate street

lighting, heavy rain, thick fog, snowfall).

Lane keeping assist(LKA)

Direct access to the Shortcuts for driving aids.

► dazzle (e.g. headlamps of an oncoming

vehicle, low sun, reflections on a damp

road, leaving a tunnel, alternating shade

and light).

For more information, refer to the General

recommendations on the use of driving

and manoeuvring aids.

Deactivation is confirmed by the

illumination of this indicator lamp on

the instrument panel.

► windscreen area located in front of the

camera (e.g. dirty, misted, frost-covered,

snow-covered, damaged or masked by a

sticker).

Due to legal requirements, the system

can only be deactivated in the vehicle

personalization until the next time the ignition

is reactivated.

The system is automatically activated by

default every time the engine is started.

Malfunction

This warning lamp lights up on the

instrument panel with the message

"Audible Warning System fault:

Repair needed" if the audible

warning system is in failure.

► lane markings absent, worn, hidden (e.g.

snow, mud, dead leaves) or multiple

(roadworks).

The system will inform the driver with a

message and an audible signal if there is

an ongoing correction for more than 10 s. If

the driver is still unable to keep the vehicle in

the lane, the correction interrupts after a short

time.

The system may be disturbed or unavailable.

Have it checked by a PEUGEOT dealer or a

qualified workshop.

► close to the vehicle ahead (lane markings

not detected).

► roads that are narrow, winding.

In the event of a malfunction, this

warning lamp lights up on the

Driving

The system corrects the vehicle's trajectory by

alerting the driver as soon as it detects 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).

steering wheel.

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).

This warning lamp flashes during

trajectory correction.

Important

When hands-off driving is detected during

a correction within a rolling interval of 180

seconds, the system intervenes:

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.

Intervention 1: flashes until the end of

the intervention.

Intervention 2: flashes and a warning

chime sounds until the end of

intervention but for at least one second.

Fault

audible signal is given. Consult a workshop.

sounds 10 seconds longer than the previous

chime.

LKA shall be deactivated by the driver when the

vehicle is being towed.

This system is particularly useful on

motorways and main roads.

This symbol appears in the Driver In-

formation Centre in the event of a

fault, accompanied by a display mes-

sage and a warning chime. Seek the

assistance of a workshop.

Operating conditions

Operation

► Vehicle speed between 40 and 112 mph (65

and 180 km/h).

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.

► Road marked with a central dividing line.

► Steering wheel held with both hands.

► Direction indicators off upon activation of the

system.

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.

Function status

OFF

Display

Comments

Function deactivated.

System active, conditions not met:

-Speed below 40 mph (65 km/h).

-No lane marking recognised.

-ESC operation triggered.

None.

-Dynamic driving style.

Automatic deactivation/standby of the function (e.g. detection of a trailer,

use of the "space-saver" type spare wheel supplied with the vehicle, fail-

ure).

Lane marking detected.

Speed above 40 mph (65 km/h).

The system corrects the trajectory on the side where the risk of line cross-

ing is detected.

None.

The driver's hands are on the steering wheel.

If, while correcting the trajectory, the system determines that the correction

will not be enough and that a solid line will be crossed: the driver is warned

that they must provide additional trajectory adjustment.

If the steering wheel is not held properly, an audible warning sounds,

accompanied by a message, until the trajectory correction is completed or

the driver has grasped the steering wheel correctly.

"Hold the steering wheel" or "Stay in

lane" (depending on version)

The duration of audible warnings will increase if multiple corrections are

performed in quick succession. The warning will become continuous, per-

sisting until the driver responds.
