Locking separately
Push the switch in the direction of arrow 1.
The luggage compartment lid is locked and
cannot be unlocked using the central locking
system.
If you give the remote control without the inte-
grated key to someone else while the glove
compartment is locked, the luggage compart-
ment lid cannot be opened. This is an advan-
tage when valet parking, for example. Locking
the glove compartment, refer to page87.
Unlocking separately
Push the switch in the direction of arrow 2.
Emergency release
Pull the lever in the cargo bay. The luggage
compartment lid is unlocked.
Closing
The handle recesses on the interior trim of the
luggage compartment lid make it easier to pull
down.Make sure that the closing path of the
luggage compartment lid is clear, other-
wise injuries may result.<
Coupe
Convertible
To close the luggage compartment lid,
press it down lightly. The lid is closed
automatically.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened
>To movements inside the vehicle: Interior
motion sensor, refer to page26
>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
>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:

Opening and closing
26 >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.
You can open the luggage compartment lid
using the button of the remote control even
if the alarm system is armed, refer to page20.
The lid is locked and monitored again as soon
as it is closed.
Panic mode*
You can trigger the alarm system if you find
yourself in a dangerous situation:
Press the button for at least three seconds.
To switch off the alarm: press any button.
Switching off an alarm
>Unlock the car with the remote control, refer
to page19.
>Insert the remote control all the way into the
ignition lock.
Indicator lamp displays
>The indicator lamp under the inside rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking:
doors, hood or luggage compartment lid are
not properly closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx. 10 seconds. The interior motion sensor and
the tilt alarm sensor are not activated.
>The indicator lamp goes out after unlocking:
your vehicle has not been disturbed while
you were away.
>If the indicator lamp flashes after unlocking
until the remote control is inserted in the
ignition, but for no longer than approx.
5 minutes: your vehicle has been disturbed
while you were away.
Tilt alarm sensor
The tilt 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
In order for the interior motion sensor to func-
tion properly, the windows and glass roof must
be completely closed
*.
Convertible
The interior of the car is monitored up to the
height of the seat cushions. Thus the alarm sys-
tem is activated together with the interior
motion sensor even if the hardtop is open. The
alarm can be triggered unintentionally by falling
objects such as leaves, refer to Avoiding unin-
tentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In duplex garages
>During transport on car-carrying trains,
boats/ships 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
again as soon as the vehicle is locked.

Under the hood
116
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
Releasing
Pull the lever.
Opening
To avoid damage, make sure that the
wiper arms are against the windshield
before you open the engine compartment. Do
not open the engine hood before the engine has
cooled down, otherwise injuries may result.<
Press the release handle and open the hood.
Closing
Close the hood from a height of approx. 20 in/
50 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 see any signs while driving your vehicle
that the hood is not completely closed, stop at
once and close it securely.<

Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Specified engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Do not use oil additives as these may
cause engine damage.<
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Viscosity ratings
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Approved oils belong to the 10W-60 SAE
class.<
Alternative oil types
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 following specifications:
>Viscosity:
preferred: SAE 10W-60;
alternative: SAE 10W-40, SAE 5W-50 or
SAE 10W-50
>Specification:
API SJ/CF, API SK/CF or higher
Low ambient temperatures
The oils used at BMW factories for your vehicle
type are suitable for virtually any ambient tem-
perature. However, if the vehicle is operated at
temperatures below –47/–206 for extended
periods, your BMW center will be glad to rec-
ommend an optimal oil.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives, otherwise
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
