Safety -> Electronic stability programme (ESC) for Your Citroen C4 Grand Picasso SUV Second Generation (2013-2022)

Safety  
Electronic stability programme (ESC)  
Electronic Stability Programme (ESC:  
Electronic Stability Control) incorporating the  
Definitions  
Anti-lock braking system (ABS)  
and electronic brake force  
distribution (EBFD)  
This system improves the stability and  
manoeuvrability of your vehicle when braking  
and provides improved control in corners, in  
particular on poor or slippery road surfaces.  
The ABS prevents wheel lock in the event of  
emergency braking.  
Anti-slip regulation (ASR)  
The ASR 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.  
following systems:  
-
the anti-lock braking system (ABS) and the  
electronic brake force distribution (EBFD),  
the emergency braking assistance,  
the anti-slip regulation (ASR) or traction  
control,  
-
-
-
the dynamic stability control (DSC).  
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 according 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, the DSC 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")  
Operation  
Your vehicle has a system to help driving on  
snow: intelligent traction control.  
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.  
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.  
In extremely severe conditions (deep snow,  
mud, ...), when it proves impossible to move off,  
it may be useful to temporarily deactivate the  
ESP/ASR systems to allow the wheels to spin  
freely and so allow movement of the vehicle.  
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.  
You must stop as soon as it is safe to do so.  
In both cases, contact a CITROËN dealer or a  
qualified workshop.  
The use of snow tyres is strongly  
recommended on surfaces offering low levels  
of adhesion.

Safety  
Deactivation  
Operating fault  
If this warning lamp comes on,  
In exceptional conditions (starting a vehicle  
which is bogged down, stuck in snow, on soft  
ground...), it may be advisable to deactivate  
the DSC system, so that the wheels can move  
freely and regain grip.  
accompanied by an audible signal  
and a message, this indicates a fault  
with the system.  
Contact a CITROËN dealer or a qualified  
workshop to have the system checked.  
But it is recommended that the system be  
reactivated as soon as possible.  
Press the button.  
The DSC system offers exceptional  
safety in normal driving, but this should  
not encourage the driver to take extra  
risks or drive at high speed.  
The correct operation of the system  
depends on observation of the  
manufacturer's recommendations  
regarding the wheels (tyres and rims),  
the braking components, the electronic  
components and the assembly and  
repair procedures used by CITROËN  
dealers.  
Dynamic stability control  
(DSC)  
This warning lamp and the indicator  
lamp in the button come on: the  
DSC system no longer acts on the  
operation of the engine.  
6
Activation  
This system is activated automatically each  
time the vehicle is started.  
It comes into operation in the event of a grip or  
trajectory problem.  
Reactivation  
The system is reactivated automatically each  
time the ignition is switched back on or from  
30 mph (50 km/h).  
This is indicated by flashing of this  
warning lamp in the instrument panel.  
After an impact, have the system  
checked by a CITROËN dealer or a  
qualified workshop.  
Press the button again to  
reactivate it manually.
