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

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
>Switching on the hazard warning flashers
>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.

Opening and closing
24 Manual operation of the tailgate triggers
the alarm. Refer to page21.<
Switching off an alarm
>Unlock the car with the remote control, refer
to page19.
>Turn the master key in the ignition lock to
position 1, refer to page40.
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 the vehicle on car-carry-
ing trains, by ship or on a trailer
>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.<

Under the hood
Do not work on the car unless you pos-
sess the necessary technical knowledge.
If you are unfamiliar with the statutory guide-
lines, have any work on the vehicle performed
only by a BMW center or by a workshop that
work according to BMW repair procedures with
correspondingly trained personnel. If this work
is not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<
Hood
To release
Pull the lever located under the left-hand side of
the instrument panel.
To open
Press the release handle and open the hood.
To close
Close the hood from a height of approx. 16 in/
40 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
hood is clear, otherwise injuries may
result.
If you notice while driving that the hood is not
completely closed, stop immediately and close
it securely.<

Adding engine oil
Do not add the maximum amount of 1 US quart/
1 liter of engine oil until the warning lamp lights
up in the instrument cluster, refer to page92, or
until the oil level monitor shows "+1.0".
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the warnings on
the containers. Otherwise, health hazards may
result.<
Oil change
Have your oil changed only by a BMW center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
continuously approves specific oils after con-
firming their suitability for use in its vehicles
with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or other approved syn-
thetic oils. 1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Do not use any oil additives, as they could
cause engine damage under some cir-
cumstances.<
Viscosity classes
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.
Coolant
Warning lamp
The warning lamp lights up:
The coolant level is too low. Top up the
coolant as soon as possible.
Do not open the cooling system when the
engine is hot. If you do, escaping coolant
can cause burns.<
Coolant consists of water and coolant additives.
Not all commercially available additives are suit-
able for your BMW. Your BMW center knows
which additives are appropriate.
Only use approved additives, otherwise
the engine could be damaged. The addi-
tives are hazardous to health.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking the coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
