Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the 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 lamp 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.

Each master key contains a rechargeable bat-
tery that is automatically recharged when it is in
the ignition lock while the car is being driven.
Use the master key at least twice a year in order
to keep the batteries 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.

You can obtain new keys, whether as additional
keys or replacement keys, at your BMW center.
Vehicle Memory, Key Memory
How the system functions
You can have your BMW center program a vari-
ety of functions on your BMW according to your
individual requirements.
Vehicle Memory refers to vehicle-oriented set-
tings and Key Memory refers to person-ori-ented settings. You can have up to four different
basic settings adjusted for four different per-
sons. The only requirement is that each person
uses his or her own master key with remote
control.
When your vehicle is unlocked with the remote
control, the vehicle recognizes the individual
user by means of a data exchange with the key,
and makes adjustments accordingly.
Colored decals were provided with the keys to
help you distinguish between the different per-
sonal remote control keys.
What the system can do
You can learn about the entire array of features
that Vehicle Memory and Key Memory offer you
at your BMW center.
You will see this symbol throughout the
Owner's Manual. It is to remind you at
appropriate places of the settings that are avail-
able to you.<
Depending on how the memory functions
are configured, the vehicle may be oper-
ated differently from what is described in the
Owner's Manual. Should you decide to sell your
BMW one day, please remember to have the
memory functions returned to their original fac-
tory settings.<

unlocking your vehicle, refer to page19, 20
