simple and easy handling.
Here are a few tips so that you get the most out
of your BMW:
>It is advisable to close the convertible top
when the vehicle is parked. When closed,

Opening and closing
22 the top not only guards the passenger com-
partment from unforeseeable damage from
the weather, but also affords a degree of
protection against theft. In addition, only
keep valuables in the locked luggage com-
partment, even with the convertible top
closed
>Never mount a roof-mounted luggage rack
system on the convertible top
>To avoid damage, do not operate the con-
vertible top at temperatures below 147/
–106.
To avoid permanent damage from mois-
ture, never store the convertible top while
it is wet.
Driving when the opening or closing process
has not been completed can cause vehicle
damage or personal injury.
Do not lay objects on the convertible top, since
they could fall off when the convertible top is
operated and cause damage or injuries.
Do not reach into the convertible top mecha-
nism during opening and closing. Keep children
away from the moving parts of the convertible
top during operation.<
If possible, only operate the convertible
top with the vehicle stopped, as other-
wise the process may be interrupted.
If you set the convertible top in motion while the
vehicle is stationary and then have to start sud-
denly, for instance at a traffic light, you can still
complete the procedure by driving as slowly as
possible and again holding the corresponding
button pressed.
At higher speeds, a vacuum effect in the pas-
senger compartment can cause the convertible
top to begin fluttering. Increase the air supply
so that a low pressure draft does not occur in
the vehicle.<
Opening and closing
1To close
2To open
If at all possible, only operate the convert-
ible top if the engine is running. This

erly.<

Tilt alarm sensor
The inclination of the vehicle is monitored. The
alarm system reacts, e.g. to attempts to steal
the wheels or tow the vehicle.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger. Even
when the convertible top is open, the alarm sys-
tem including the interior motion sensor is
armed. Objects falling into the vehicle, e.g.
leaves, can trigger unintentional alarms, refer to
Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
can be deactivated at the same time. In this way
you can avoid unintentional alarms, e.g. in the
following situations:
>In duplex garages
>When the vehicle is being transported on a
car-carrying train
>If animals are to be left in the vehicle.
To deactivate the tilt alarm and interior
motion sensors
Press the button on the remote control
a second time immediately after locking.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are deactivated until
the vehicle is again unlocked and locked.

extreme angle – this also applies to the passen-
ger seat. If you do, there is a risk that you will
