19Opening the trunk lid23

Opening and closing
24 trunk lid opens slightly and can be swung
upward.
In the event of a malfunction, please con-
tact your BMW center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel.<
Locking or unlocking separately
The switch is located in the glove compartment.
1Locking the trunk lid
2Unlocking the trunk lid
Locking separately
Push the switch in the direction of arrow 1.
The trunk 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 trunk lid cannot be
opened. This is an advantage when valet park-
ing, for example. Locking the glove compart-
ment, refer to page88.
Unlocking separately
Push the switch in the direction of arrow 2.
Emergency release
Pull the lever in the cargo area. The trunk lid is
unlocked.
Closing
The handle recesses on the interior trim of the
trunk lid make it easier to pull down.
Make sure that the closing path of the
trunk lid is clear; otherwise, injuries may
result.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the trunk lid is
opened
>To movements inside the vehicle: interior
motion sensor, refer to page25
>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
page25
>When there has been an interruption of
power supply from the battery

Depending on the market-specific version, the
alarm system briefly signals unauthorized entry
attempts by:
>An acoustic alarm
>Switching on
* the hazard warning flashers
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 trunk 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, or
>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 trunk lid 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. 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 convertible top is
open. An alarm can be triggered unintentionally
by falling objects such as leaves, refer to Avoid-
ing unintentional 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

Under the hood
114
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. 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 see any signs while driving your vehicle
that the hood is not completely closed, stop at
once and close it securely.<

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 SM specification or higher.
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.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 0W-40,
0W-30, 5W-40 and 5W-30 SAE
classes.<
These oils can be used for driving at all outside
temperatures.
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.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
