ELECTRONIC STABILITY
PROGRAMME (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 ma-
noeuvrability of your vehicle when braking
and offers improved control, in particular
on poor or slippery road surfaces.
The ABS prevents wheel lock in the
event of emergency braking.
The electronic brake force distribution
system manages the braking pressure
wheel by wheel.
Operation
When this warning lamp
comes on, accompanied by a
buzzer and a message, it indi-
cates that there is a malfunc-
tion of the ABS, which can cause a loss
of control of the vehicle when braking.
When this warning lamp comes
on, connected to the STOP
warning lamp, accompanied
by a buzzer and a message,
it indicates that there is a malfunction
of the electronic brake force distribution
(EBFD), which can cause a loss of con-
trol of the vehicle when braking.
Stop immediately.
In both cases, consult a PEUGEOT
dealer.
When changing wheels (tyres
and rims), make sure that
these are approved.
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.

Snow driving assistance
(Intelligent Traction Control)
Your vehicle has a system to help driving
on snow: Intelligent Traction Control.
This automatic system continuously
checks for situations of diffi cult surface
adhesion that could make it diffi cult to
move off or make progress on deep
fresh snow or compacted snow.
In these situations, the Intelligent Trac-
tion Control system takes over from the
ASR system by optimising the amount
of wheel slip to provide the best trac-
tion and trajectory control, even without
snow tyres and with or without chains.
In extremely severe conditions (snow
on top of ice, sand, deep mud…), it can
be useful to deactivate the ESP/ASR
systems to allow a degree of wheel spin
and so recover grip.
