Indicator and warning
lamps
Technology that monitors itself
The indicator and warning lamps identified
by the
+ symbol are subjected to an oper-
ation check each time you switch on the
ignition or start the engine. They each light
up once for different periods of time.
When a malfunction occurs in a monitored
system, the corresponding lamp will either
fail to go out when the engine is started, or
it will come on again during normal driving,
usually accompanied by a Check Control
message. You will find more details on the
specified pages.
Fixed indicator and warning lampsColors The indicator and warning lamps can light
up in different colors and combinations.
>Red:
Stop immediately
or
important reminder
>Red and yellow:
Continue to drive; drive cautiously
>Yellow:
Have the system checked at the earliest
opportunity
or
for your information
>Green or blue:
For your information.
Variable indicator and warning lamps
On the display 5 of the instrument cluster,
other indicator and warning lamps appear
as necessary. Pay attention to the instruc-
tions of the accompanying Check Control
messages, also refer to page 66. Turn signals60

Indicator lamp displays
>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes on locking:
door(s) or luggage compartment lid are
not completely closed. Even if you do
not close the alerted area, the system
begins to monitor the remaining areas,
and the indicator lamp flashes continu-
ously after approx.10 seconds. How-
ever, the interior motion sensor is not
activated
>The indicator lamp goes out on unlock-
ing: no manipulation or attempted intru-
sions have been detected in the period
since the system was armed
>The indicator lamp flashes on unlocking
before the remote control is inserted in
the ignition lock, but for no more than
roughly 5 minutes: an attempted entry
has been detected in the period since
the system was armed.
Following triggering of an alarm, the indica-
tor lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if some-
one attempts to steal the wheels or tow the
vehicle.
Interior motion sensor
Coupe:
In order for the interior motion sensor to
function properly, the windows and glass
roof must be completely closed.
Convertible:
Monitors the interior up to the height of the
seat cushions. This means that the alarm
system, including the interior motion sen-
sor, is armed even if the convertible top is
open. Falling objects, e.g. leaves, can trig-
ger false alarms, refer to Avoiding uninten-
tional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. This is how you prevent unintentional
alarms, e.g. in the following situations:
>In garages with elevator ramps
>During transport on automobile trans-
port trains
>If animals are to remain in the vehicle.
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote con-
trol once again directly after locking.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor are
switched off until the vehicle is unlocked
and locked again.
Windows
To prevent injuries, exercise care
when closing the windows and keep
them in your field of vision until they are
shut.
When leaving the vehicle, always remove
the ignition key and close the doors to pre-
vent children from operating the windows
and injuring themselves etc.<

Anti-trapping mechanism
If the closing force rises beyond a pre-
defined threshold during closing, the sys-
tem will immediately stop moving the win-
dow prior to lowering it slightly.
Convertible: the back windows and
rear window are not equipped with an
anti-trapping mechanism.<
Despite the anti-trapping mechanism,
you should always inspect the front
side window's travel path prior to closing it,
as the safety feature might fail to detect
certain kinds of obstructions, such as very
thin objects, and the window would con-
tinue closing.
Pulling the switch beyond the resistance
point and holding it limits the response of
the anti-trapping mechanism. Under these
conditions, the window will respond to
forces beyond a defined threshold by only
opening a few inches/millimeters.
If you again pull the switch past the resis-
tance point and hold it in position within a
period of roughly 4 seconds, the anti-trap-
ping mechanism will be deactivated.<
Accessories in window area
After installing any accessory – such as a
clamp-on antenna for a portable phone –
within the window's travel range, you will
need to have the system reinitialized for
use under the new conditions. Please con-
tact your BMW center for assistance.
Coupe:
Glass roof, electric with
raise function*
To prevent injuries, exercise care
when closing the glass roof and keep
it in your field of vision until it is shut.
When leaving the vehicle, always remove
the key and close the doors, as otherwise
children could operate the roof and injure
themselves etc.<

Convertible: top
The fully automatic convertible top com-
bines secure weather protection with sim-
ple and convenient operation.
So that you get the maximum pleasure from
your convertible, here are a few tips:
>It is recommended that you close the
convertible top when the vehicle is
parked. The closed convertible top not
only protects the passenger compart-
ment against unforeseen weather dam-
age, it also represents a certain protec-
tion against theft. Nonetheless, even if
the convertible top is closed, only keep
valuables in the locked luggage com-
partment
>Do not attach luggage rack systems to
the convertible top
>At temperatures below 147/–106,
do not operate the convertible top, as
otherwise damage can occur.
Do not leave the soft top in the con-
vertible top compartment for longer
than one day when wet, as otherwise dam-
age from moisture can occur.
Do not place any objects on the convertible
top, as otherwise if the top was to be oper-
ated, they would fall off and lead to damage
or injury.
Never move the convertible top when the
rollover protection system is raised.
Driving without having completed the
opening or closing action can lead to dam-
age or injury.
Do not place hands in the top mechanism
during the opening and closing action.
Keep children away from the travel path of
the convertible top.
For safety reasons, only operate the con-
vertible top when the vehicle is at a stand-
still.<
If you have initiated top operation with
the vehicle at a standstill and then
drive off, e.g. at a traffic light, you can con-
tinue the initiated operation up to a speed
of 20 mph/30 km/h.
To do so, press and hold the correspond-
ing button.<

Opening and closing
38 Partial vacuums that occur at higher
speeds in the passenger compart-
ment can make the convertible top flap.
Use the ventilation controls to increase the
air supply so that no partial vacuum occurs
in the vehicle.<
To close the electrically activated side
windows while the vehicle is being
driven, always close the rear windows or
all four windows simultaneously first, as
otherwise the windows cannot close tightly
at higher speeds.<
Prior to opening and closing
>Read carefully and comply with the
safety precautions that appear above
>Ensure that the convertible top com-
partment floor in the luggage compart-
ment is folded down, refer to page 32,
as otherwise the convertible top cannot
be opened
>Ensure that the luggage compartment
lid is closed.
Opening and closing
As of ignition key position 1, with the vehi-
cle stationary:
So as not to place an excessive load
on the battery, only operate the con-
vertible top with the engine running, if pos-
sible.
Before closing the convertible top, remove
foreign bodies from the windshield frame,
as these might inhibit closing of the con-
vertible top.<

Interruption
The automatic sequence of movements is
interrupted immediately if the button for top
operation is released. The sequence can
be continued in the desired direction using
the button.
If the opening or closing action is
interrupted for a longer period by
releasing the button, the convertible top
remains in that position for approx. 15 min-
utes before it slowly moves to a stable
position. The sequence can be continued
using the buttons.

action several times in succession, as oth-
erwise the fully automatic top mechanism
can be damaged.
