Mobility
System
Concept
With
the
Mobility
System,
minor
tire
damage
can be
sealed
temporarily
to
enable
continued
travel.To
accomplish
this,
sealant
is
pumped
into
thetires,
which
seals
the
damage
from
the
inside.
General
information'xFollow
the
instructions
on
using
the
Mobility
System
found
on
the
compressor
and

of
the
Mobility
System

In
this
case,
have
the
electronics checked
and

There
is
danger
to
life.
Keep

Tire
pressure
monitor
Concept The
system
monitors
tire
inflation
pressure
in
thefour
mounted
tires.
The
system
warns
you
if there
is
a
loss
of
pressure
in
one
or
more
tires.
General
information Sensors
in
the
tire
valves
measure
the
tire
infla#jtion
pressure
and
tire
temperature.
Using
the
tire
settings
in
iDrive,
the
system
can
automatically
compare
the
specified
target
pres#j
sures
with
the
actual
tire
inflation
pressures.
If
tires
are
being
used
that
are
not
specified
on the
tire
inflation
pressure
details
on
the
vehicle,
such
as
tires
with
special
approval,
the
system
needs
to
be
actively
reset.
The
system
will
then
take
over
the
actual
tire
inflation
pressures
as
the
target
pressures.
When
operating
the
system,
also
note
the
infor#j mation
found
in
the
Tire
