Safety  
05  
For technical reasons, in particular to  
improve the quality of telematic services  
for customers, the Manufacturer reserves the  
right to carry out updates to the vehicle's  
on-board telematic system at any time.  
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 dealer or a qualified  
workshop.  
If you benefit from the DS CONNECT BOX  
offer with the SOS and Assistance Pack  
included, you have available additional  
services in your personal space, via the  
website in your country.  
For information about the SOS and Assistance  
Pack, please refer to the general conditions for  
these services.  
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 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.  
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.  
Electronic stability control  
(ESC)  
The electronic stability control programme  
includes the following systems:  
– Anti-lock braking system (ABS) and Electronic  
brake force distribution (EBFD).  
– Emergency braking assistance (EBA).  
– Anti-slip regulation (ASR).  
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.  
You must stop as soon as it is safe to do so.  
Contact a dealer or a qualified workshop.  
The normal operation of the ABS may  
result in slight vibrations in the brake  
pedal.  
– Dynamic stability control (DSC).  
– Trailer stability assist (TSA).  
When braking in an emergency, press very  
firmly and maintain this pressure.

These systems are activated automatically every  
time the vehicle is started.  
They come into operation in the event of a grip or  
trajectory problem.  
ASR / DSC  
stabilise the trailer and, if necessary, reduces  
engine power to slow down the vehicle.  
This warning lamp flashes in the  
instrument panel and the brake lamps light  
up to draw attention to this corrective action.  
For information on towed loads and masses, refer  
to the Technical data section or your vehicle’s  
registration certificate  
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 dealers.  
This warning lamp on the instrument panel  
flashes to indicate that they are operating.  
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.  
Deactivation / reactivation is confirmed by the  
display of a message.  
To ensure complete safety while driving with a  
Towing device, refer to the corresponding section.  
Malfunction  
If a fault occurs, this warning lamp comes  
on in the instrument panel, accompanied  
by a message and an audible signal.  
If you wish to continue towing a trailer, reduce  
your speed and drive carefully!  
The use of snow tyres is recommended, to  
ensure that these systems remain effective  
in winter conditions. All four wheels must be  
fitted with tyres approved for the vehicle.  
Contact a dealer or a qualified workshop to have  
the system checked.  
The ASR system is reactivated automatically  
every time the ignition is switched back on or  
from 31 mph (50 km/h).  
The trailer stability assist system offers  
enhanced safety in normal driving,  
Trailer stability assist (TSA)  
When towing, this system reduces the risk of the  
vehicle or trailer snaking.  
Reactivation is manual below 31 mph (50 km/h).  
provided that the recommendations on towing  
a trailer are observed. It should not encourage  
the driver to take risks, such as towing a trailer  
in adverse operating conditions (overloading,  
failure to observe the trailer nose weight, worn  
or under-inflated tyres, faulty braking system,  
etc.), or to drive at excessive speeds.  
Malfunction  
In the event of a system malfunction, this  
warning lamp comes on, accompanied by  
an onscreen message and audible signal.  
Contact a dealer or a qualified workshop to have  
the systems checked.  
Operation  
The system is activated automatically when the  
ignition is switched on.  
The electronic stability control system (ESC) must  
not have any faults.  
Between 37 and 99 mph (60 and 160 km/h), if  
the system detects oscillations (snaking) in the  
movement of the trailer, it acts on the brakes to  
In certain cases, the system may not detect  
trailer snaking, particularly with a light trailer.
