The ESPsystem offers
increased safety during
normal driving, but should
not incite the driver to take
risks or to drive at high speed.
The operation of the system is
assured to the extent to which the
recommendations of the manufac
turer regarding the wheels (tyres
and wheel rims), the braking com
ponents, the electronic compo
nents and the assembly and repair
procedures within the PEUGEOT
network are respected.
After an accident or impact, have
the system checked by a
PEUGEOT dealer.

TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and com
plement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by act
ing on the brakes of the drive wheels
and on the engine. It also allows the
directional stability of the vehicle to
be improved on acceleration.
If there is a variation between the tra
jectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle
back on course.
Operation of the ASR and ESP
systems
When one of these two sys
tems is operating, this light
flashes. Handbrake
Applying
When parking, pull the handbrake to
immobilise your vehicle.
W
arning: when parking on a slope,
direct your wheels towards the pave
ment and apply the handbrake.
Releasing
Pull the handle and press the button
to release the handbrake.
Disarming the ESP / ASR systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...),
it could prove useful to disarm the
ASR system to make the wheels
spin and regain grip. 
Press the switch "ESP OFF", sit
uated to the left of the steering
wheel.
The switch lights up and the indicator
lights come on, accompanied by the
message '' ASR/ESP deactivated''
on the multifunction display: the
ESP and ASR systems no longer
affect the operation of the engine or
the brakes.
They engage again: automatically when the ignition is
switched off,
 manually by pressing the switch
again.
Operating check When a system malfunction
occurs, the switch light
flashes and the indicator
light comes on.
