Traction control: ASR
TRACTION CONTROL: ASR (1/2)
This system helps to limit wheelspin of
the drive wheels and to control the vehi-
cle when pulling away or accelerating.
This function is an addi-
tional aid in the event of
critical driving conditions,
enabling the vehicle behav-
iour to be adapted to suit the driving
conditions.
However, the function does not take
the place of the driver. It does not
increase the vehicle’s limits and
should not encourage you to
drive more quickly.
Therefore, it can under no circum-
stances replace the vigilance or re-
sponsibility of the driver when ma-
noeuvring the vehicle (the driver
must always be ready for sudden in-
cidents which may occur when driv-
ing).
Operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and slows
down their over-rotation.
If a wheel is starting to slip, the system
brakes automatically until the drive sup-
plied becomes compatible with the level
of grip under the wheel again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal.
When the function begins to operate,
warning light A flashes to warn you.
