key unlocks the driver's door only.
A second unlock request
unlocls the remaining doors and trunk. This feature can be
modified for individual users with the Key Memory capabil-
ities to activate all lock actuators simultaneously See Car
Memory
/ Key Memory later in this section.
Starting with 2000 models, the battery in the FZV ignition
Icey is recharged by the ignition switch ring antenna while
the ley is in the ignition switch.

Car Memory 1 Key Memory
A number of features and functions can be customized to the
driver(s) preference. The identity of the vehicle user is provid-
ed by a
s~gnal from the keyless entry system (FZV).
Car Memory and Key Memory are actually two separate func-
tions, although they are marketed as a combined feature.
Car Memory
Pr'or ro new
veh c,e de very, the BMW scan roo (DISp us,
GTI or MOD C) is ~sed lo cooc ine driver preierences nro ine
appropriate control modules. Thereafter these choices can-
not be changed without
recoding with a BMW scan tool.
The functions that can be set using Car Memory include:
Alarm system (DWA) features such as armingldisarming
with
lkeyless entry (FZV), activation of tilt sensor or interior
sensor
lnterior light activation when central
locking is used
Convenience opening of
windows/sunroof
lnterior and external lighting preferences
Heating
I A/C preferences (IHKA)
Seat and mirror preferences (triggered by Key Memory)
Instrument cluster display units (for example: km vs. miles)

I Airbag System (SRS)
Two-stage airbag (MRS Ill)
Beginning with 2000 model year (911 999 production) the front
airbags were changed to a two-stage style airbag. This en-
sures that the force of
airbag inflation is not greater than nec-
essary to provide
protection. The airbags are designed to
Drovide "soit" de~lovment if the acceleration sensor detects a
iow-speed impact, and "hard deployment in higher speed im-
pacts.
NOTE-
A two-stage passenger airbag was used on cars built be-
tween
9/1998 and 3/1999. This pre-smart technology airbag
used two ignition stages. Stage one is designed to ignite first
during an impact. Stage two ignites after a timed period, as
programmed in the MRS
I1 control module.
Airbag indicator light
The MRS control module detects and stores system status
The
airbag indicator light in the instrument cluster displays
the status of the
airbag system when the ignition key is in "ac-
cessory" or
ON positions.
System normal: lndicator light comes on briefly, then goes
out.
- System malfunction: lndicator light fails to come on.
System malfunction: lndicator light comes on briefly, goes
out and lights up again.
The
airbag indicator light also comes on if the seat belt pyro-
technic tensioners have been triggered.
