TRAjECTORY CONTROL SYSTEMS
Anti-slip regulation (ASR) and
dynamic stability control (DSC)
The anti-slip regulation  (also  known  as  traction
 control)  optimises  traction  to  
prevent

 
skidding
 
of
 
the
 
wheels,
 
by
 
act
-
ing
 
on
 
the
 
brakes
 
of
 
the
 
driving
 
wheels
 
and

  on   the   engine.
The electronic stability control acts on
the
 
brake
 
of
 
one
 
or
 
more
 
wheels
 
and
 
on

 
the
 
engine
 
to
 
keep
 
the
 
vehicle
 
on
 
the
 
trajectory

 
required
 
by
 
the
 
driver
,  
within
 
the

  limits   of   the   laws   of   physics.
Activation
These
 
systems
 
are
 
activated
 
automati
-
cally
  each   time   the   vehicle   is   started.
They
 
come
 
into
 
operation
 
in
 
the
 
event
 
of

  a   grip   or   trajectory   problem.
This
 
is
 
indicated
 
by
 
flashing
 
of
 
this

 
warning
 
lamp
 
in
 
the
 
instru
-
ment
  panel.
Intelligent traction control
system ("Snow motion")Deactivation
In 
extremely
 
severe
 
conditions
 
(deep
 
snow

,  
mud,
 
...),
 
if
 
you
 
are
 
unable
 
to
 
move

 
of
f,  
it
 
may
 
be
 
useful
 
to
 
temporar
-
ily
 
deactivate
 
these
 
systems
 
so
 
that
 
the
 
wheels

 
can
 
spin
 
freely
 
and
 
allow
 
the
 

vehicle

  to   move.
F
 
Press
 
this
 
button,
 
located
 
near
 
the
 
steering

  wheel.
If
 
the
 
indicator
 
lamp
 
in
 
the
 
button
 
comes
 
on,

 
this
 
indicates
 
that
 
these
 
systems
 
are

  deactivated.
Depending
 
on

 
version,

 
your

 
vehicle

 
has

 
a

 
system

 
to

 
help

 
driving

 
on

 
snow:

 
intel

-
ligent traction control.
This
 
system

 
detects

 
situations

 
of

 
diffi

-
cult
 
surface

 
adhesion

 
that

 
could

 
make

 
it

 
difficult

 
to

 
move

 
of

f
 
or

 
make

 
progress

 
on

 
deep

 
fresh
 
snow
 
or
 
compacted
 
snow.
In these situations, the intelligent trac-
tion control
 
limits

 
the

 
amount

 
of

 
wheel

 
slip

 
to

 
provide

 
the

 
best

 
traction

 
and

 

trajectory

 
control
 
for
 
your
 
vehicle.
The
 
use
 
of
 
snow
 
tyres
 
is
 
strong-
ly
 
recommended

 
on

 
surfaces

 
of

-
fering
 
low
 
levels
 
of
 
adhesion. It
 
is
 
recommended
 
that
 
the
 
systems
 
be
 
reactivated

  as   soon   as   possible.
