Get Driving -> Active Lane Departure Warning System Guide for Citroen C5 SUV 2020

Driving

Using a camera located at the top of the

windscreen to identify lane markings on the

road and at the edges of the road (depending

on version), the system corrects the trajectory

of the vehicle while alerting the driver if it

detects a risk of unintentionally crossing a line

or hard shoulder (depending on version).

This system is particularly useful on motorways

and main roads.

Operation

The following situations may interfere with

the operation of the system or prevent it

from working:

Once the system identifies a risk of the vehicle

involuntarily crossing one of the lane markings

detected, it makes the correction to the

trajectory required to return the vehicle to its

initial path.

poor visibility (inadequate lighting of

the road, falling snow, heavy rain,

dense fog, etc.),

dazzle (headlamps of an oncoming

vehicle, low sun, reflections on a damp

road, leaving a tunnel, alternating

shade and light, etc.),

The driver will notice a turning movement of the

steering wheel.

This warning lamp flashes during

trajectory correction.

windscreen area located in front of the

camera: dirty, misted up, frost-covered,

snow-covered, damaged or covered by

a sticker,

lane markings absent, worn, hidden

(snow, mud) or multiple (roadworks,

etc.),

The driver can prevent the correction by

keeping a firm grip on the wheel (during

an avoiding manoeuvre, for example).

The correction is interrupted if the

direction indicators are operated.

Conditions for operation

close to the vehicle ahead (lane

markings not detected),

roads that are narrow, winding, etc.

The speed of the vehicle must be between

40 and 112 mph (65 and 180 km/h).

The driver must hold the wheel with both

hands.

The change of trajectory must not be

accompanied by operation of the direction

indicators.

The ESC system must not be faulty.

The ASR/DSC systems must be activated.

If the system detects that the driver is not

holding the wheel firmly enough during

an automatic correction of trajectory,

it interrupts the correction. An alert is

triggered to encourage the driver to take

back control of the vehicle.

Active Lane Departure

Warning System

Refer to the General recommendations on

the use of driving and manoeuvring aids.

The system helps the driver only when

there is a risk of the vehicle involuntarily

wandering from the lane it is being driven

in. It does not manage the safe driving

distance, the speed of the vehicle or the

brakes.

(grey)

While the direction indicators are on and for

a few seconds after switching them off, the

system considers that any change of trajectory

is voluntary and no correction is triggered

during this period.

However, with the Blind Spot Monitoring system

activated, if the driver starts changing lanes

and another vehicle is detected in the vehicle's

blind spot, the system will correct the trajectory

of the vehicle even though the direction

indicators are on.

System active, conditions not met:

speed below 40 mph (65 km/h),

no lane marking recognised,

ASR/DSC systems deactivated

or regulation by ESC system in

progress,

"sporty" driving.

Automatic deactivation/standby of the

system (e.g. detection of a trailer, use of

the "space-saver" spare wheel provided

with the vehicle).

For more information on the Blind Spot

Monitoring system, refer to the corresponding

The system goes into standby automatically in

recommended),

driving where there are no lane markings,

activation of the direction indicators,

crossing the inside line on a bend,

driving in a tight corner,

The system corrects the trajectory on

the side where the risk of involuntary

crossing is detected (orange line).

(orange)/(green)

If, during correction, the system

detects that the driver has not held

the steering wheel for a few seconds,

it interrupts the correction and returns

control to the driver.

During correction of the trajectory,

if the system determines that the

correction will not be enough and

that a solid line is crossed (orange

line): the driver is warned that they

must complete the correction of the

trajectory.

correction.

"Take back control

of the vehicle."

Driving

The following situations may interfere with

The system is not intended for driving in the

following situations:

Malfunction

the operation of the system or prevent it

from working:

driving on a speed circuit,

driving with a trailer,

driving on a rolling stand,

driving on unstable surfaces.

conditions of poor visibility (inadequate

street lighting, snowfall, rain, fog),

dazzle (headlamps of an oncoming

vehicle, low sun, reflections on a damp

road, leaving a tunnel, alternating

shade and light),

In the event of a fault with the system, you are

alerted by the illumination of these warning

lamps in the instrument panel, accompanied by

the display of a message and an audible signal.

Have the system checked by a CITROËN

dealer or a qualified workshop.

Deactivation/Activation

The system is activated every time the ignition

is switched on.

windscreen area located in front of the

camera: dirty, misted, frost-covered,

snow-covered, damaged or covered by

a sticker,

lane markings worn, hidden (snow,

mud) or multiple (roadworks, etc.),

(the lane markings may not be

detected),

Active Blind Spot

Monitoring System

roads that are narrow, winding,

insufficient contrast (shade, for

example) between the road and the

edges of the road.

Refer to the General recommendations on

the use of driving and manoeuvring aids.

F To deactivate the system, press this button.

Deactivation is signalled by the

lighting of the indicator lamp in

the button and this warning lamp on

the instrument panel.

Risk of undesirable operation

Deactivation of the system is recommended in

the following situations:

Reactivation is by another press, the indicator

lamp in the button and the warning lamp switch

off.

driving on a road surface in poor condition,

unfavourable climatic conditions,

driving on slippery surfaces (ice).
