Get Safety -> Electronic stability control (ESC) Guide for Citroen Ds5 SUV First Generation (2011-2018)

Electronic stability control (ESC)

A set of the following Electronic Stability

systems:

definitions

Anti-lock braking system (ABS)

and electronic brake force

distribution (EBFd)

These systems improve the stability and

manoeuvrability of your vehicle when braking

and contribute towards improved control in

corners, in particular on poor or slippery road

surfaces.

Anti-slip regulation (ASR)

-

anti-lock braking system (ABS) and

electronic brake force distribution (EBFD),

emergency braking assistance,

wheel anti-slip regulation (ASR) or traction

control,

This system (also known as Traction Control)

optimises traction in order to avoid wheel

slip by acting on the brakes of the driving

wheels and on the engine. It also improves

the directional stability of the vehicle on

acceleration.

-

dynamic stability control (DSC).

The ABS prevents wheel lock in the event of

emergency braking.

The electronic brake force distribution system

manages the braking pressure wheel by wheel.

Emergency braking

assistance

dynamic stability control

(dSc)

In an emergency, this system enables you to

reach the optimum braking pressure more

quickly and therefore reduce the stopping

distance.

It is triggered in relation to the speed at which

the brake pedal is pressed. This is felt by a

reduction in the resistance of the pedal and an

increase in the effectiveness of the braking.

If there is a difference between the path

followed by the vehicle and that required by the

driver, this system monitors each wheel and

automatically acts on the brake of one or more

wheels and on the engine to return the vehicle

to the required path, within the limits of the laws

of physics.

Safety

Intelligent traction control

system ("Snow motion")

Depending on version, your vehicle has a

system to help driving on snow: intelligent

traction control.

This system detects situations of difficult

surface adhesion that could make it difficult to

move off or make progress on deep fresh snow

or compacted snow.

In these situations, the intelligent traction

control limits the amount of wheel slip to

provide the best traction and trajectory control

for your vehicle.

Operation

Anti-lock braking system (ABS)

and electronic brake force

distribution (EBFd)

When changing wheels (tyres and rims),

make sure that these are approved for

your vehicle.

Normal operation of the ABS may make

itself felt by slight vibrations of the brake

pedal.

When this warning lamp comes on,

accompanied by an audible signal

and a message, it indicates that there

is a fault with the ABS, which could

cause loss of control of the vehicle

when braking.

In emergency braking, press

very firmly without releasing the

pressure.

When this warning lamp comes on,

coupled with the STOP warning lamp,

accompanied by an audible signal and a

message, it indicates that there is a fault

with the electronic brake force distribution

(EBFD), which could cause loss of control

of the vehicle when braking.

The use of snow tyres is strongly

recommended on surfaces offering low

levels of adhesion.

You must stop as soon as it is safe to do so.

In both cases, contact a CITROËN dealer or a

qualified workshop.

Reactivation

In exceptional conditions (starting a vehicle

which is bogged down, stuck in snow, on soft

ground...), it may be advisable to deactivate

the DSC and ASR, so that the wheels can turn

freely and regain grip.

The systems are reactivated automatically each

time the ignition is switched back on or from

30 mph (50 km/h).

Below 30 mph (50 km/h), you can reactivate

them manually:

F

Press this button again.

Reactivate the systems as soon as the level of

grip permits.

The indicator lamp in the button

goes off.

F

Press this button.

dynamic stability control (dSc)

and anti-slip regulation

(ASR)

The indicator lamp in the button

comes on.

The DSC and ASR systems no longer act

on the operation of the engine and on the

brakes in the event of a involuntary change of

trajectory.

Operating fault

Activation

These systems are activated automatically

each time the vehicle is started.

As soon as they detect a problem of grip or

trajectory, these systems act on the operation if

the engine and brakes.

Illumination of this warning lamp and

the lamp in the deactivation button,

accompanied by an audible signal

and a message, indicate a fault with

the system.

Contact a CITROËN dealer or a qualified

workshop to have the system checked.

This is indicated by flashing of this

warning lamp in the instrument panel.

Safety

After an impact, have these systems

checked by a CITROËN dealer or a

qualified workshop.

dSc/ASR

The DSC and ASR systems offer increased

safety in normal driving, but they should not

encourage the driver to take extra risks or

drive at high speed.

It is in conditions of reduced grip (rain,

snow, black ice) that the risk of loss of grip

increases. It is therefore important for your

safety to keep the DSC and ASR systems

activated in all conditions, and particularly

in difficult conditions.

The correct operation of these systems

depends on observation of the

manufacturer's recommendations regarding

as much the wheels (tyres and rims),

braking and electronic components as the

assembly and repair procedures used by

CITROËN dealers.

To benefit in full from the effectiveness

of the DSC and ASR systems in wintry

conditions, the vehicle must be fitted with

four snow tyres, allowing the the vehicle to

retain neutral handling on the road.
