Driving safely
ANTI-SLIP REGULATION (ASR)
AND ELECTRONIC STABILITY
PROGRAMME (ESP)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting 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.
Use the ESP to hold your course without
attempting to countersteer.
If there is a variation between the trajectory
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.
In certain exceptional conditions (when
starting a vehicle stuck in mud or snow, or
on loose ground...), it could prove useful
to deactivate the ASR system to make the
wheels spin and regain grip.
Operation of the ASR and ESP
systems
The LED flashes when the ASR or ESP is
triggered.
Press this button.
The LED on the button comes on: the
ASR system no longer acts on the engine
operation, but continues to act on the brakes.
Operating fault
When a malfunction of the ASR
system occurs, this warning lamp
comes on, accompanied by an
audible signal and confirmed by a
message on the screen.
