ELECTRONIC STABILITY
P
ROGRAMME
(
ESP
)
Electronic stability programme (ESP)
incorporating the following systems:
- the anti-lock braking system (ABS)
and the electronic brake force distri-
bution system (EBFD),
- the emergency braking assistance,
- the traction control (ASR),
- the dynamic stability control (DSC).
Definitions
Anti-skid regulation (ASR)
The ASR system (also known as Trac-
tion 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)
If there is a difference between the path
followed by the vehicle and that re-
quired 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.
Emergency braking assistance
In an emergency, this system enables
you to reach the optimum braking pres-
sure 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 effec-
tiveness of the braking.
Anti-lock braking system (ABS) and
electronic brake force distribution
system (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when
braking and offers improved control, in
particular on poor or slippery road sur-
faces.
The ABS prevents wheel lock in the
event of emergency braking.
The electronic brake force distribution
system manages the braking pressure
wheel by wheel.
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.
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 distribu-
tion (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 PEUGEOT
dealer or a qualifi ed workshop.
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.
In emergency braking, press
very fi rmly without releasing
the pressure.
