Harder
vehicle
braking
In
certain
situations,
it
may
be
necessary
to
bring
the
vehicle
to
a
standstill
more
quickly.
To
do
this,
for
a
short
time
the
braking
pressure
applied
when
stepping
on
the
brake
pedal
must
be
higher
than
the
braking
pressure
achieved
by
the
automatic
braking
function.

and
regulations
when
using
the
corresponding
functions
and

Anti-lock
Brake
SystemABS
ABS
prevents
the
wheels
from
locking
when
thebrakes
are
applied.
Steering
control
is
retained
even
in
the
event
of full
braking,
thereby
enhancing
active
road safety.
ABS
is
ready
to
operate
each
time
the
engine
is started.
Brake
assist
When
the
brake
pedal
is
depressed
quickly,
the
system
automatically
applies
maximum
braking
power
assistance.
By
doing
so,
the
braking
disj
tance
is
kept
as
short
as
possible
in
full
braking
situations.
The

be
maintained for
the
duration
of
the
full-braking
process.
Adaptive

M
Sport
differential
The
active
M
Differential
blocks
the

steplessly,
depending
on
the

This
prevents
the
spinning
of

Integral
Active
Steering
Principle
The
Integral
Active
Steering
increases
agility
and enables
more
direct
steering
behaviour.
General
Integral
Active
Steering
is
a
combination
of
a
varj iable
steering
ratio
and
rear-wheel
steering.
The
variable
steering
ratio
amplifies
the
steering angle
when
manoeuvring,
thus
making
the
steerjing
more
direct.
The
rear-wheel
steering
increaj
ses
manoeuvrability
at
low
speeds
by
turning
the
rear
wheels
slightly
in
the
opposite
direction
to the
front
wheels.
At
higher
speeds,
the
rear
wheels
are
turned
in the
same
direction
as
the
front
wheels.
This
rejsults
in,
for
example
better
directional
stability
and
a
smoother
change
of
direction.
In
critical
driving
situations,
for
example
overj
steer,
Integral
Active
Steering
can
stabilise
the
vehicle
through
selective
steering
of
the
rear
wheels
before
the
driver
intervenes.
Configuration
The
system
offers
various
configurations.Drive

Operation
with

chains
To
ensure
that
wheels
can
move
as
required when
using
snow
chains,
the
rear-wheel

the
Integral
Active

must
be
switched
off
when
snow

are
fitted.
Setting

with
snow
chains,
see
page

Malfunction
If
a
malfunction
occurs,
the
steering
wheel
must
be
turned
further,
while
at
high
speeds
the
vehij cle
responds
more
sensitively
to
steering

movements.
The
