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

●

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level; top off as
required. If the oil level is correct:
please contact the nearest BMW cen-
ter.
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.

30Opening and closing
KeysThe key set1Master keys with remote control unit
– these keys determine the functions
of the Key Memory. Refer to page 70.
You can mark the individual keys for
subsequent identification by apply-
ing 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.
For this reason, if you have master keys
with the remote control feature that are
not being used otherwise, use those
keys at least once a year while driving
for an extended period to charge the
battery.<
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 34.
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.

31
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 32.
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 32.
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 41 or 46, 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 driver's door lock or with the
remote control, 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 32. The lid is once again
secured when it is closed.
Extended pressure on the button sets
off the alarm – Panic mode, refer to
page 32.

After the ignition has been
switched offYou can still use the electric power win-
dows for up to 15 minutes, as long as
no one opens any of the doors.Safety featureIf the closing force of a front window
exceeds a certain value as the window
is being closed, the closing procedure
is immediately interrupted and the win-
dow opens again slightly.
Despite this protective function,
you must still make sure that there
are no obstacles within the closing
range of the windows. Otherwise, it
cannot be guaranteed that the closing
procedure will be interrupted in certain
cases, e.g. when very thin objects are
in the closing range.
This protective function is deactivated
when the switch is pulled past the
resistance point and held there. nected, the protective function must be
reinitialized. Please refer the problem to
your BMW center.
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.<

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.<

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
