Get Driving -> Active Lane Keeping Assist Guide for Citroen C5 SUV 2020

Driving

When the driver must suspend the cruise

control system:

Malfunction

Pay particular attention:

When motorcycles are present and

when there are vehicles staggered

onto the traffic lane.

If the cruise control

malfunctions, dashes are

displayed instead of the

cruise control speed setting.

When entering a tunnel or crossing

a bridge.

If this warning lamp comes

on, accompanied by an

alert message and an

audible signal, this confirms

a malfunction.

If one of these malfunctions occurs, do not

use the system:

Vehicles in a tight bend.

When approaching a roundabout.

Following an impact on the windscreen

close to the camera or on the front

bumper (versions with radar).

Brake lamps not working.

Have the system checked by a CITROËN

dealer or a qualified workshop.

Active Lane Keeping

Assist

If the vehicle has been subject to one of

the following modifications, do not use the

system:

When following a narrow vehicle.

Reactivate cruise control when conditions

permit.

Carrying long objects on roof bars.

Towing.

Cases where the driver is urged to take

back control immediately:

Use of the "space-saver" type spare

wheel (depending on version).

Front end of the vehicle modified

(addition of long-range headlamps,

painting of the front bumper).

Excessively sharp deceleration of the

vehicle in front of you.

Refer to the General recommendations on

the use of driving and manoeuvring aids.

Using a camera located at the top of the

windscreen, the system identifies lane

markings and steers the vehicle inside this lane

to keep it in the lateral position chosen by the

driver.

When a vehicle cuts in sharply between

your vehicle and the one in front.

Driving

This function is primarily suitable for driving on

motorways and main roads.

(orange colour)

The system has a fault.

Activation/Deactivation

The state of the system stays in the

memory when the ignition is switched off.

Conditions for operation

If the driver no longer wishes to benefit from

the system for a while, they can deactivate it by

pressing the button again.

The indicator lamp in the button goes off and

the symbol disappears from the instrument

panel.

The adaptive cruise control must be active.

The vehicle must be travelling in a traffic

lane clearly delimited by lines on both sides.

The ESC system must be operating.

The ASR/DSC systems must not be

deactivated.

No trailer detected.

A spare wheel of the "space-saver" type

must not be in use.

The vehicle must not be subject to strong

lateral accelerations.

The direction indicators must not be

activated.

Cruise control

The driver must hold the steering wheel

properly.

With the adaptive cruise control activated, press this

button.

When cruise control is activated, the symbol is

displayed in green: by small steering actions,

the system directs the vehicle and keeps it in

the position chosen by the driver, in the traffic

lane.

The action is confirmed by:

Illumination of the indicator lamp in the button in green.

Display of the following symbol in the instrument panel.

The colour of the symbol depends on the

operating state of the system:

The driver can feel movements in the steering

wheel.

This position is not necessarily the centre of

the lane.

(grey colour)

At least one of the operating

conditions is not met, the system is

paused.

The driver can change the position of the

vehicle at any time, by turning the steering

wheel. When the driver feels that the vehicle's

position is appropriate, whilst keeping hands

on the steering wheel, they must release the

pressure to let the system resume control of the

steering, but the vehicle is not centred within

the lane automatically.

(green colour)

All operating conditions are met, the

system is active.

152

Driving

Automatic pausing:

Pausing/Suspension of the

system

Driving situations and

associated alerts

Triggering of the ESC.

Prolonged failure to detect one of the lane

limit markings. In this case, the active lane

departure warning function can take over,

and the system will reactivate itself once the

operating conditions are again met.

The tables below describe the displays

associated with the main driving situations. The

display of these alerts is not sequential.

The driver must intervene as soon as

they believe that the traffic conditions or

the state of the road surface make this

necessary, by moving the steering wheel

to suspend the system temporarily. Any

action at the brake pedal which results in

the cruise control being paused will also

cause the system to be paused.

On action by the driver: suspension

Activation of the direction indicators.

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 (pausing until the

cruise control is reactivated) or accelerator

pedal (suspension for as long as the pedal

is pressed).

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 reaction

from the driver.

Pausing the cruise control.

Deactivation of the DSC/ASR systems.

After suspension due to the prolonged

release of the force holding the steering

wheel, you must reactivate the function by

pressing the button again.

covered, damaged or masked by a sticker.

Lane markings eroded, partially hidden

(snow, mud) or multiple (roadworks, surface

joints).

Recommendations on care

Regularly check that the front bumper and

the area of the windscreen located in front

of the camera are clean.

Refer to the General recommendations on

the use of driving and manoeuvring aids.

Regularly check that the windscreen wipers

are in good condition.

In bad weather, or during the winter, ensure

that the front bumper and windscreen are

not covered with mud, ice or snow.

Travelling in a tight bend.

Winding roads.

Presence of a tarmac joint on the road.

This system allows:

the driver to be warned that their vehicle is

at risk of collision with the vehicle in front,

a pedestrian or, depending on version, a

cyclist,

a collision to be prevented, or its severity to

be limited, by reducing the vehicle's speed.
