WARNING
Only
apply
the
brakes
for
the
purpose
of
cleaning
the
brake
system
when
road
and
traffic
conditions
permit.
You
must
not
en-
danger
other
road
users
and
increase
the
risk of
an
accident.
Due
to
the
risk
of
injury,
only
have
an
au-
thorized
Audi
dealer
or
authorized
Audi
Service
Facility
work
on
the
brake
system.
Incorrect
repairs
could
impair
the
function.
Never
let
the
vehicle
roll
while
the
engine
is
stopped
because
this
increases
the
risk
of
an
accident.
During
automatic
braking
maneuvers,
the
brake
pedal
may
move
downward
automati-
cally.
To
reduce
the
risk
of
injury,
do
not
place
your
foot
under
the
brake
pedal.
@)
Note
Never
let
the
brakes
“rub”
by
pressing
the
pedal
lightly
when
braking
is
not
actually
necessary.
This
can
cause
the
brakes
to
over-
heat
and
increases
braking
distance
and
causes
wear.
Observe
the
important
information

ing

This
especially
ap-
plies
when
towing

Tips
In
vehicles
with
an
electromechanical
brake
booster,
the
resistance
in
the
brake
pedal
may
vary
depending
on
the
driving
situation
(such
as
if
driver
assistance
system
are
ac-
tive).
If
you
retrofit
your
vehicle
with
a
front
spoil-
er,
wheel
covers
or
similar
items,
make
sure
that
the
air
flow
to
the
brakes
is
not
ob-
structed.
Otherwise
the
brake
system
can
overheat.
