Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the ignition key is turned. They each light up
once for different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding light does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

The key set
1Master keys with remote control
Each key is powered by an extended-life
battery that is charged automatically in the
ignition lock as you drive. For this reason,
use every master key at least twice a year to
keep its battery charged. Depending on
which master key is recognized when the
vehicle is unlocked, different settings are
called up and carried out in the vehicle, refer
to Key Memory on page31.
2Spare key
For storage in a safe place, e.g. in your wal-
let.
This key is not intended for constant use.
New keys
You can obtain new keys, whether as additional
keys or replacement keys, at your BMW center.
Central locking system
The concept
The central locking system is ready for opera-
tion whenever the driver's door is closed. The
system simultaneously engages and releases
the locks on the
>doors
>luggage compartment lid
>fuel filler door>storage compartment between the back-
rests
>opened manual convertible top.
The central locking system can be operated
>from outside using the remote control or via
the driver's door lock
>from inside via the central locking system
button.
If it is operated from inside, the fuel filler door
will not be locked. Refer to page18.
The anti-theft system is automatically activated
whenever you activate the central locking sys-
tem from outside the vehicle. It prevents the
doors from being unlocked with the lock but-
tons or release handles. The alarm system is
also armed.
In the event of a sufficiently severe accident, the
central locking system unlocks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
from outside
With the remote control
Whenever you unlock or lock the vehicle, you
simultaneously deactivate/activate the anti-
theft system, disarm/arm the alarm system and
switch the interior lamps on/off.
You will find more information about the alarm
system on page25.
Since persons or animals in the vehicle
could lock the doors from the inside,
always take the vehicle keys with you so that
the vehicle can be opened again from the out-
side at any time.<
To unlock
Press the button.

Windows
To open and close a window
Ignition key in position 1 or higher:
>Press the switch downward until you feel
resistance: the window continues to move
downward as long as you continue to press
the switch
>Tap the switch past the pressure point:
the window moves downward automati-
cally. Tapping the switch again stops the
opening cycle.
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 the ignition has been switched off
You can still open or close the windows for up to
15 minutes, as long as no one opens any of the
doors.
When leaving the vehicle, always remove
the ignition key from the lock and remem-
ber to close the doors, since children could oth-
erwise operate the windows and injure them-
selves, etc.<
For convenience operation via the remote con-
trol or the door lock, refer to page17 or18,
respectively.
Pressure-sensitive finger guard
system
If the closing force exceeds a certain value while
a window is being raised, the system will
respond by stopping the window and then
retracting it a small distance.Despite the finger guard system, make
sure that the windows can close without
obstruction, since in some cases, e.g. with thin
objects, it is not guaranteed that the closing
operation will be interrupted.
The finger guard system function is restricted
when the switch is pulled and held beyond the
pressure point.<
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pressure-
sensitive finger guard system must be reinitial-
ized:
Ensure that the doors and convertible top are
closed before initializing. Perform the following
procedure twice for each window:
>Open and close the window completely
>With the window closed, keep pulling the
switch upward for approx. 1 second.
Manual convertible top
The fabric top offers perfect protection against
the weather and it can be opened easily and
quickly by one person alone.
Here are a few tips so that you get the most out
of your BMW:
>It is advisable to close the convertible top
when the vehicle is parked. The closed con-
vertible top not only protects the passenger
compartment from unforeseeable damage
from the weather, but also provides a cer-
tain degree of theft protection
>In addition, only keep valuables in the
locked luggage compartment, even with the
convertible top closed
>When the convertible top is open, the cen-
tral locking system also locks the release
button for the convertible top. The convert-
ible top cannot be operated. This provides
better theft protection for valuables stored
in the luggage compartment
>Never mount a roof-mounted luggage rack
system on the convertible top.

Opening and closing
22 the top not only guards the passenger com-
partment from unforeseeable damage from
the weather, but also affords a degree of
protection against theft. In addition, only
keep valuables in the locked luggage com-
partment, even with the convertible top
closed
>Never mount a roof-mounted luggage rack
system on the convertible top
>To avoid damage, do not operate the con-
vertible top at temperatures below 147/
–106.
To avoid permanent damage from mois-
ture, never store the convertible top while
it is wet.
Driving when the opening or closing process
has not been completed can cause vehicle
damage or personal injury.
Do not lay objects on the convertible top, since
they could fall off when the convertible top is
operated and cause damage or injuries.
Do not reach into the convertible top mecha-
nism during opening and closing. Keep children
away from the moving parts of the convertible
top during operation.<
If possible, only operate the convertible
top with the vehicle stopped, as other-
wise the process may be interrupted.
If you set the convertible top in motion while the
vehicle is stationary and then have to start sud-
denly, for instance at a traffic light, you can still
complete the procedure by driving as slowly as
possible and again holding the corresponding
button pressed.
At higher speeds, a vacuum effect in the pas-
senger compartment can cause the convertible
top to begin fluttering. Increase the air supply
so that a low pressure draft does not occur in
the vehicle.<
Opening and closing
1To close
2To open
If at all possible, only operate the convert-
ible top if the engine is running. This
saves unnecessary battery wear.
Before closing the convertible top, remove any
objects from the windshield frame that could
keep the convertible top from closing prop-
erly.<
Ignition key in position 1 or higher.
With the vehicle standing.
1.Read and comply with the preceding safety
precautions
2.Make sure that the convertible top com-
partment panel in the luggage compart-
ment is lowered; refer to page19. Other-
wise the convertible top cannot be opened
3.Ensure that the luggage compartment lid is
closed
4.Press and hold the corresponding button
for convertible top operation.
If the convertible top should halt right before the
closing phase is completed, press against the
front part of the convertible top frame from the
outside to help the closing process along. Keep
pressing the button while doing so until the top
starts up again on its own.
Indicator lamps
>The red indicator lamp in the button will
light up while the convertible top is in
motion. It goes out as soon as the opening
or closing operation has been completed
>If the red indicator lamp in the button
flashes after the button has been released,

Doors or luggage compartment lid are not
completely closed. Even if you do not close
the area causing the alert, the remaining
areas are secured and the indicator lamp
flashes continuously after 10 seconds.
However, the interior motion sensor is not
activated
>If the indicator lamp goes out immediately
after the vehicle is unlocked:
No manipulation or attempted intrusions
have been detected in the period since the
system was armed
>If the indicator lamp flashes for 10 seconds
immediately after the vehicle is unlocked:
An attempted entry has been detected in
the period since the system was armed.
After an alarm has been triggered, the indicator
lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
The inclination of the vehicle is monitored. The
alarm system reacts, e.g. to attempts to steal
the wheels or tow the vehicle.
Interior motion sensor*
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 the vehicle is being transported on a
car-carrying train
>If animals are to be left in the vehicle.
To deactivate the tilt alarm and interior
motion sensors
Press the button on the remote control
a second time immediately after locking.
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.

Adjustments
Safe seating position
For relaxed driving with as little fatigue as pos-
sible, you should select a seating position that
reflects your personal requirements. In combi-
nation with the safety belts and airbags, the cor-
rect seating position also plays an important
role in enhancing occupant safety in the event
of an accident. To ensure that the vehicle's
safety systems provide you with optimal pro-
tection, we request that you direct your careful
attention to the following section.
For supplementary information on transporting
children refer to page33.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 and 3 o'clock positions to minimize the
r i s k o f i n j u r i e s t o y o u r h a n d s o r a r m s i n t h e e v e n t
of airbag deployment.
Never allow any objects, individuals or animals
to obstruct the areas between passengers and
airbags.
Never use the front airbag's cover as a storage
tray or support for objects of any kind. Ensure
that the passenger is correctly seated, i.e. does
not prop feet or legs against the dashboard.
Otherwise, leg injury could result if the knee air-
bag and front airbag suddenly deployed.
Never let an occupant's head rest near or on a
side airbag because the inflating airbag could
cause a serious or fatal injury.<
Even when all these guidelines are observed,
the risk of injury as a result of contact with the
airbags cannot entirely be ruled out in some sit-
uations. In sensitive individuals, the ignition and
inflation noise may induce a mild hearing loss
that is temporary in most cases.
For airbag locations and additional information
on airbags, refer to page53.
Safety belts
Always fasten your safety belt before starting
off. As supplemental restraint devices, the air-
bags are designed to enhance the effective-
ness of the safety belts, and not to replace
them.
Your vehicle offers two sitting positions, each of
which is equipped with a safety belt.
At all times, occupants should sit upright
and be properly restrained: infants and
small children in appropriate child-restraint sys-
tems; larger children and adults using the safety
belts.
Expectant mothers should always wear their
safety belts, taking care to position the belt in
the pelvic area against the lower hips, where it
will not exert pressure against the abdomen.
N e v e r a l l o w m o r e t h a n o n e p e r s o n t o w e a r a si n -
gle safety belt. Never allow infants or small chil-
dren to ride in a passenger's lap.
Do not route the belt across your neck, or run it
across sharp edges. Be sure that the belt does
not become caught or jammed. Avoid twisting
the belt while routing it firmly across the hips
and shoulder; wear it as snugly against your
body as possible. Do not allow the belt to rest
against hard or fragile objects. Otherwise, the
belt in the pelvic area could slide over the hips in
the event of a frontal impact, leading to abdom-
inal injury. Avoid wearing bulky clothing and pull
the belt in the upper-body area upward periodi-
cally to retension it. Otherwise, the restraining
effect of the safety belt could be diminished.<
For information on using the safety belts, refer
to page30.

Damaged safety belts
If the safety belts are damaged or
stretched in an accident: have the entire
belt system, including the tensioning mecha-
nisms, replaced at your BMW center. Have the
belt anchorage points inspected for damage at
the same time. Failure to observe this precau-
tion may prevent the safety belts from effec-
tively providing optimal protection when
needed.<
