Make sure that the closing path of the
luggage compartment lid is clear, other-
wise injuries may result.<
Cargo bay
Emergency release
Pull the lever in the cargo bay. The luggage
compartment lid/tailgate is unlocked.
Roadster: increasing cargo bay
capacity
The cargo bay can be enlarged when the con-
vertible top is closed.Turn the handles on both sides of the cargo bay
outward beyond the resistance point at the
same time, arrow 1.
The convertible top compartment panel swings
up, arrow 2.
Before opening the convertible top:
Turn both handles inward.
The convertible top compartment panel is
folded down.
To avoid any damage when opening the
convertible top, make sure that the con-
vertible top compartment panel in the cargo bay
has been folded down.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid/tailgate is opened
>When attempts are made to start the vehi-
cle
>When there are movements in the vehicle
interior: interior motion sensor, refer to
page24
>When the car's inclination changes, for
instance if an attempt is made to jack it up
and steal the wheels or to raise it prior to
towing away: Tilt alarm sensor, refer to
page24
>When there is an interruption in the power
supply from the battery
The alarm system signals unauthorized entry
attempts for a short time by means of:
>An acoustic alarm

Opening and closing

>Flashing the high beams
Arming and disarming
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
The hazard warning flashers light up once when
the alarm system has been properly armed.
You can have different acknowledgment
signals set to confirm arming and disarm-
ing.<
Even when the alarm system is armed, you can
open the luggage compartment lid/tailgate
using the button on the remote control,
refer to page19. When you subsequently close
the luggage compartment lid/tailgate, it is
locked again and monitored.
Manual operation of the luggage com-
partment lid/tailgate triggers the alarm.
Refer to page21.<
Switching off an alarm
>Unlock the car with the remote control, refer
to page19, or
>turn the master key in the ignition lock to
position 1, refer to page38
Indicator lamp displays
>The indicator lamp beneath the interior mir-
ror flashes continuously:
The system is armed.
>The indicator lamp flashes immediately
after the vehicle is locked:
Doors, hood or luggage compartment lid/
tailgate are not properly closed. Even if you do not close the alerted area, the system
begins to monitor the remaining areas, and
the indicator lamp flashes continuously
after approx. 10 seconds. However, the
interior motion sensor is not activated.
>If the indicator lamp goes out immediately
after the vehicle is unlocked:
Your vehicle has not been disturbed while
you were away.
>If the indicator lamp flashes for 10 seconds
immediately after the vehicle is unlocked:
Your vehicle has been disturbed while you
were away.
After an alarm has been triggered, the indicator
lamp will flash continuously.
Tilt alarm sensor
The inclination of the vehicle is monitored. The
alarm system reacts e.g. to attempts to steal a
wheel or tow the vehicle.
Interior motion sensor*
Coupe
All windows must be closed in order for the inte-
rior motion sensor to function optimally.
Roadster
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 transporting on car-carrying trains
>When animals are to remain in the vehicle

Switching off tilt alarm sensor and
interior motion sensor
>Press the button on the remote
control twice in a row.
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.
Windows
To prevent injuries, exercise care when
closing the windows and keep them in
your field of vision until they are shut.
Take the key with you when you leave the car,
otherwise children could operate the windows
and possibly injure themselves.<
Opening, closing
Ignition key in position 1 or higher:
>Press the switch downward to the resis-
tance point.
The window continues to open as long as
you press the switch.
>Press the switch beyond the resistance
point.
The window opens automatically. Press the
switch again to stop the opening move-
ment.
You can close the window in the same manner
by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After switching off the ignition
You can still open or close the windows for
approx. 1 minute, as long as no one opens any
of the doors.
For convenience operation via the remote con-
trol or the door lock, refer to page19 or20,
respectively.
Pinch protection system
If the closing force exceeds a certain value while
a window is being raised, the system responds
by stopping the window and then retracting it a
short distance.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories within the win-
dows' range of movement; otherwise the pinch
protection system could be impaired.<
The closing force can change as a result
of extreme temperature fluctuations. The
window then opens slightly after closing even if
there is no obstacle within the window's travel
path. If this occurs, override the pinch protec-
tion system.<
Pulling the switch beyond the resistance point
and holding it there overrides and deactivates
the pinch protection system.
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pinch pro-
tection system must be reinitialized.
Roadster: when the convertible top has
been stored in the convertible top com-
partment for an extended period of time, e.g. in
the winter months because the hardtop was
being used, it may also be necessary to reinitial-
ize the pinch protection system.<
Ensure that the doors and the Roadster's con-
vertible top are closed before initializing.

Intermittent mode
Not in vehicles with a rain sensor.
Rotary dial 5 is used to set the wipe interval to
one of four levels.
In addition, the wipe interval is varied automati-
cally depending on road speed.
Rain sensor*
On vehicles with a rain sensor, the wipe interval
is automatically controlled according to rain
intensity. The sensor is mounted on the wind-
shield, directly in front of the interior rearview
mirror.
Deactivate the rain sensor before enter-
ing an automatic car wash. Failure to do
so could result in damage caused by undesired
wiper activation.<
Activating
With the ignition key in position 1 or higher,
move the lever to position 1.
In any case, the wipers will move once across
the windshield.
You can leave the lever continuously in
position1. Then, as long as the ignition key is in position 1 or higher, you only need to activate
the rain sensor.
To do so:
>Turn rotary dial 5 briefly or
>Clean the windshield, refer to Cleaning
windshield and headlamps* below
Adjusting sensitivity
Turn the rotary wheel 5.
Deactivating
Flip the lever to position 0.
Normal wiper speed
When the vehicle is stopped the wipers auto-
matically switch to intermittent wipe, except in
vehicles with a rain sensor.
Fast wiper speed
When the vehicle is stopped the wipers operate
at normal wiping speed, except in vehicles with
a rain sensor.

Do not use the washers if there is any
danger that the fluid will freeze on the
windshield, otherwise vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid on
page44.
Do not operate washing mechanisms when the
washer fluid reservoir is empty, otherwise you
will damage the washer pump.<

automatic climate control does not have
enough time to achieve the set temperature.<
AUC Automatic recirculated-air
control/Recirculated-air mode
Switch on the desired operating
mode by pressing this button repeat-
edly:
>LEDs off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the inflow of outside air is shut off perma-
nently. The system recirculates the air
within the vehicle.
If the windows fog over in the recircu-
lated-air mode, you should switch it off
and, if necessary, increase the air flow rate.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the car will deteriorate contin-
uously.<
Rear window defroster
The defroster switches off automati-
cally after a certain time.
Ventilation
1Knurled wheels to set any vent position
from fully open to closed
2Slide for adjusting air flow direction
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air toward you, for instance if it has become too
hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
Center replaces this combined filter during reg-
ular maintenance. A substantial reduction in air
flow indicates that the filter needs to be
replaced earlier.

Under the hood
88 The warning lamp lights up in yellow
within 30 seconds after the engine is
started: The oil level sensor is defec-
tive:
It is not possible to issue a current or accurate
measurement. Have the system checked as
soon as possible.
Checking the oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil level reading displayed in
the instrument cluster.
Press button1. The oil level is checked and dis-
played for approx. 15 seconds.
To exit the display sooner, press button 1 again.
Possible displays
1Oil level OK
2Oil level is being checked.
This can take about 3 minutes if the car is at
a standstill on a level surface, or about
5 minutes while the car is on the move.
3Oil level down to minimum:
Add 1US quart/1liter of engine oil as soon
as possible, refer also to Adding engine oil.
4Oil level is too high.
Have the vehicle checked immedi-
ately, as excessive oil can damage the
engine.<
5The oil level sensor is defective:
it is not possible to issue a current or accu-
rate measurement.
Do not add engine oil. You can continue
your journey. Have the system checked as
soon as possible.
