SAFETY
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 en-
gine and the brake of one or more
wheels, in order to put the vehicle
back on course, within the limits of
the laws of physics. In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground, ...), it may
be advisable to disarm the ASR and
ESP systems, so that the wheels can
move freely and regain grip.

 Press the "ESP OFF" switch, lo-
cated on the central section of the
fascia. Operating check
The ESP/ASR systems offer
exceptional safety in normal
driving, but this should not
encourage the driver to take
extra risks or drive at high speed.
The correct functioning of these
systems depends on observation of
the manufacturer's recommenda-
tions regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
PEUGEOT assembly and operation
procedures.
After an impact, have the systems
checked by a PEUGEOT dealer.
