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 dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react in the follow-
ing section.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

The engine oil pressure is too
low. Stop the vehicle immedi-
ately and switch off the engine. It is not
possible to continue driving. Please
contact the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: there is a flat tire.
Reduce speed and carefully come to a
stop. Avoid sudden braking and steer-
ing maneuvers.

28Opening and closing
KeysThe key set1Master keys with remote control.
They govern the functions of the Key
Memory. Certain functions in your
vehicle may operate differently
depending on the key, refer to
page 68.
To distinguish between keys, you can
mark each key with remote control by
applying one of the colored decals
that you received when accepting
delivery of your vehicle
In every master key with the
remote control feature there is an
extended-life battery that is charged
automatically in the ignition lock as you
drive.
Therefore, use otherwise unused mas-
ter keys for a longer journey every six
months so that the battery can be
charged.<
2Spare key – for storage in a safe
place, such as in your wallet. This key
is not intended for constant use. The
luggage compartment lid and the
glove compartment cannot be locked
and unlocked with this key. This is
useful for valet parking, for example
Central locking systemThe conceptThe central locking system engages
and releases the following locks at the
same time:
>doors
>luggage compartment lid
>fuel filler door
>glove compartment.
The central locking system is ready for
operation whenever the driver's door is
closed.
The central locking system can be
operated
>from outside via the door lock as well
as via the remote control
>from inside by pressing a button.
The fuel filler door is not locked when
the central locking system is activated
from the inside, refer to page 32.
When the system is actuated from the
outside, the anti-theft system is also
activated. This prevents the doors from
being unlocked via the lock buttons or
the release handle. The alarm system is
also activated or deactivated.
The central locking system is automati-
cally deactivated in the event of an
accident. In addition, the hazard warn-
ing flashers and interior lamps come on.

29
Opening and closing – via the remote controlThe conceptThe remote control also provides two
additional functions beyond the central
locking feature:
>To switch on interior lamps, refer to
page 30.
With this function you can also
search for the vehicle when parked in
an underground garage, for instance
>To open the luggage compartment
lid, refer to page 30.
The luggage compartment lid will
open slightly, regardless of whether it
was previously locked or unlocked.
Whenever you unlock or lock the vehi-
cle, you simultaneously deactivate/acti-
vate the anti-theft system, disarm/arm
the alarm system and switch the interior
lamps on/off.
You can have a signal set to con-
firm that the vehicle's locks have
engaged securely.<
Master keys with remote control
Persons or animals inside the
vehicle may be able to lock the
doors from the inside. For this reason,
you should always take the vehicle keys
with you so that the vehicle can be
opened again from the outside at any
time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery.
To prevent unauthorized use of the
remote control, surrender only the
spare key when leaving the vehicle for
valet parking, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Before lowering the convertible
top, refer to page 39 or 44, always
check to ensure that the luggage com-
partment panel is folded down. Other-
wise damage could occur.<
Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movements inside the vehicle –
interior motion sensor
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle – tilt alarm sensor
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the remote control or the driver's
door lock, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can open the luggage compart-
ment lid when the system is armed by
pressing the remote control button,
refer to page 30. The lid is once again
secured when it is closed.
Extended pressure on the button sets
off the alarm – Panic mode, refer to
page 30.

Despite trap protection, always
make sure that the windows can
close without obstruction, otherwise in
some cases, e.g. with thin objects, it is
not guaranteed that the closing opera-
tion will be interrupted.
Trap protection is restricted when the
switch is pulled and held beyond the
pressure point. In this instance, if the
closing force exceeds a certain value,
the window will re-open just a few milli-
meters.
If the switch is pulled and held beyond
the pressure point again within approx.
4 seconds, trap protection is overrid-
den.<
After a power lossAfter the battery has been discon-
nected, the trap protection must be
reinitialized. Perform the following pro-
cedure twice:
>Open and close the window com-
pletely
>With the window closed, keep pulling
the switch for approx. 1 second.
Manual convertible topThe fabric top offers the perfect protec-
tion against weather and one person
can open and close it easily and simply.
To gain maximum satisfaction from your
convertible, please observe the follow-
ing: we strongly recommend that you
close the convertible top before leaving
the vehicle parked. When closed, the
top not only guards the passenger
compartment from unforeseeable dam-
age from the weather, but also affords a
degree of protection against theft.
However, even when the top is closed
valuables should always be stored in
the locked luggage compartment.
Never attempt to mount any kind of roof
rack or luggage carrier on the convert-
ible top.
Closing the electric power win-
dows: to help ensure that the win-
dows seal securely, you should either
close the rear windows first or close all
four windows at the same time.<

ment lid is closed
4. Maintain pressure on the corre-
sponding button for the convertible
top operation.
It can take a few seconds until the
opening or closing procedure starts.
The luggage compartment lid can-
not be opened while the convert-
ible top is in motion.<
While the convertible top is in
motion, the rear window will move
toward the passenger compartment. To
avoid possible pinching, the area
around the closing convertible top
should be clear.<
After having been stored for an
extended period of time in the
convertible top compartment, e.g. dur-
ing the winter months because the
hardtop was being used, you may have
to support the convertible top by hand
when closing it for the first time.
If the convertible top should halt just
before the closing phase is completed,
press against the front section of the
convertible top frame from the outside
to help the closing process along. Con-
tinue pressing the switch while doing
so until the top starts up again on its
own.<
Indicator lamps>The red indicator lamp is lit whenever
the convertible top mechanism is in
motion. It goes out as soon as the
opening or closing operation has
been completed
>If the red indicator lamp flashes after
the control button is released, the
convertible top has not yet been
opened or closed completely. You
can resume operation in the desired
direction by pressing the button
again.
