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 page33
>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 has been an interruption of
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.
You can open the trunk lid even when the alarm
system is armed, by pressing the button on
the remote control, refer to page28. The lid is
locked and monitored again as soon as you
close it.
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 page27.
>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 m o t i o n s e n s o r a n d
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.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the next time the vehicle is unlocked and subse-
quently locked again.
Comfort Access*
Comfort Access enables you to enter your vehi-
cle without needing to hold the remote control
in your hand. All you need to do is wear the
remote control close to your body, e.g. in your
jacket pocket. The vehicle detects the corre-
sponding remote control within the immediate
vicinity or in the passenger compartment.
Comfort Access supports the following func-
tions:
>Unlocking/locking the vehicle
>Unlocking the trunk lid separately
>Engine starting
>Convenient closing

Under the hood

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
In order to avoid damage, make sure that
the wiper arms are against the windshield
before you open the hood. 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
Let the hood drop from a height of approx.
10 in/25 cm. 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.<

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
suitable 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.
