Safety -> Electronic stability control (ESC) for Your Citroen C4 Cactus SUV Second Generation (2018-2024)

Safety  
You must stop as soon as it is safe to do so.  
Contact a CITROËN dealer or a qualified  
workshop.  
Anti-slip regulation (ASR)  
/ Dynamic stability control  
(DSC)  
Anti-slip regulation optimises traction using  
engine braking and by applying the brakes on  
the driving wheels to avoid wheel spinning. It  
also enhances the vehicle's directional stability  
while accelerating.  
If there is a difference between the vehicle’s  
trajectory and the path desired by the driver, the  
dynamic stability control system automatically  
uses engine braking and the brakes on one or  
more wheels to return the vehicle to the desired  
path, within the limits of the laws of physics.  
These systems are activated automatically every  
time the vehicle is started.  
Electronic stability control  
(ESC)  
The electronic stability control programme  
includes the following systems:  
The normal operation of the ABS may  
result in slight vibrations in the brake  
pedal.  
– Anti-lock braking system (ABS) and Electronic  
brake force distribution (EBFD).  
– Emergency braking assistance (EBA).  
– Anti-slip regulation (ASR).  
When braking in an emergency, press  
very firmly and maintain this pressure.  
– Dynamic stability control (DSC).  
When changing wheels (tyres and rims),  
ensure that these are approved for your  
vehicle.  
Anti-lock braking system  
(ABS) and Electronic brake  
force distribution (EBFD)  
These systems enhance the vehicle’s stability  
and handling during braking, and enable greater  
control while cornering, particularly on poor or  
slippery road surfaces.  
After an impact, have these systems  
checked by a CITROËN dealer or a  
qualified workshop.  
They come into operation in the event of a grip  
or trajectory problem.  
ABS prevents wheel locking in the event of  
emergency braking.  
EBFD manages the braking pressure wheel by  
wheel.  
This warning lamp comes on fixed in the  
event of an ABS malfunction.  
The vehicle retains conventional braking. Drive  
carefully at a moderate speed.  
Contact a CITROËN dealer or a qualified  
workshop as soon as possible.  
This warning lamp, when lit together with  
the STOP and ABS warning lamps,  
accompanied by a message and an audible  
signal, indicates an EBFD malfunction.  
This warning lamp on the instrument  
panel flashes to indicate that they are  
operating.  
Emergency braking  
assistance (EBA)  
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 braking efficiency.  
Deactivation / Reactivation  
In exceptional conditions (starting a vehicle stuck  
in mud, immobilised in snow, on soft ground,  
etc.), it may be useful to deactivate the ASR  
system to freely spin the wheels and regain  
traction.  
Reactivate the system as soon as the level of  
grip permits.  
It is set via the Driving / Vehicle touch  
screen menu.

Safety  
Deactivation is confirmed by the  
illumination of this indicator lamp in the  
instrument panel and the display of a message.  
The ASR system is reactivated automatically  
every time the ignition is switched back on or  
from 31 mph (50 km/h).  
in winter conditions. All four wheels must be  
fitted with tyres approved for the vehicle.

Seat belts  
Reactivation is manual below 31 mph (50 km/h).  
Front seat belts  
Malfunction  
In the event of a system malfunction, this  
warning lamp comes on, accompanied by  
an onscreen message and audible signal.  
Contact a CITROËN dealer or a qualified  
workshop to have the systems checked.  
► Pull the strap then insert the tongue in the  
buckle.  
ASR / DSC  
► Check that the seat belt is fastened correctly  
by pulling the strap.  
These systems enhance safety during  
normal driving, but should not encourage  
the driver to take extra risks or drive at high  
speed.  
It is in conditions of reduced grip (rain, snow,  
ice) that the risk of loss of grip increases. It  
is therefore important for your safety to keep  
these systems activated in all conditions, and  
particularly in difficult conditions.  
Correct operation of these systems depends  
on compliance with the manufacturer's  
recommendations relating to the wheels  
(tyres and rims), braking and electronic  
components, as well as the assembly and  
repair procedures used by CITROËN dealers.  
The use of snow tyres is recommended, to  
ensure that these systems remain effective  
Release  
► Press the red button on the buckle.  
► Guide the seat belt as it reels in.  
The front seat belts are fitted with a pyrotechnic  
pretensioning and force limiting system.  
This system improves safety in the front seats  
in the event of a front or side impact. Depending  
on the severity of the impact, the pretensioning  
system instantly tightens the seat belts against  
the body of the occupants.  
The pretensioning seat belts are active when the  
ignition is on.  
The force limiter reduces the pressure of the  
seat belt on the chest of the occupant, thus  
improving their protection.
