contained unit. The control electronics are integrated into the
gear drive that is part of the motor assembly. The control elec-
tronics contain two hall sensors, one
forthe park position and
one
forthe end stop or to signal reverse direction of the wiper
motor.

Airbags
Front airbags, s~de a~rbags, pyrotechnic seat belt tensioners
and the Battery Safety Terminal (BST) are integrated into the
Supplemental Restraint System (SRS) and its variants.
NOTE-
The BMW SRS system is called Multiple Restra~nt System
(MRS). Over the years,
E39 cars were equipped with MRS,
MRS
11, MRS 111. Each version offers varied features and im-
provements over the previous system.
< As many as 8 airbags may be installed in E39 cars, depend-
ing on model and MRS version.
The front
airbags operate without sodium azide propellant,
widely considered an irritant when an
airbag is deployed.
Starting with
1999 models. "smart"front passenger and driver
airbags were installed. These are of the dual-threshold, dual
stage design, including a
sensorto help prevent the unneces-
sary deployment of the passenger side
airbag if the seat is un-
occupied.
MRS control Depend~ng on options chosen, one airbag may be installed in module each door of the sedan and Sport Wagon models, protecting
passengers against
s~de impacts.
Head Protection System (ITS)
airbags strelch diagonally
across the tops of the front doors.
Airbag deployment automatically triggers fuel shutoff, turns
on the hazard and interior lights, and unlocks the doors.
- -
WARNING -
Airbags are inflated by an explosive device. Handled im-
properly or without adequate safeguards,
airbag units can
be very dangerous. Special precautions must be observed
prior to any worlc at or near any of the airbags. See
721 Air-
bag System (SRS).
Always disconnect the battery and cover the negative
(-) battery terminal with an insulator before starting di-
agnostic, troubleshooting or service work on cars fitted
with SRS, and before doing any welding on the
car.

Battery safety terminal
(BST)
4 Starting with 1999 models (9198 production and later), a py-
rotechnic (explosive charge) device automatically discon-
nects the battery positive terminal during impacts. Key
features,
like power windows and door locks, remain opera-
tional.
Security
Electronic immobilization (EWS)
Ignition key transponder signal All
E39 vehicles incorporate an electronic immobilization sys-
tem known as EWS. This svstem uses a wireless comrnuni-
cation link between a transponder chip in the ignition key and
the ring antenna surrounding the ignition switch. The EWS
control module blocks the starting of the vehicle unless the
correct coded ignition key is used.
NOTE-
Electronic immobilization is sometimes referred to as the
driveaway protection system.
Antitheft alarm (DWA)
This is adealer-installed option for which the E39 vehicles are
factory-wired. When armed, the system monitors door
loci(
contacts and trunk and engine hood locks and sounds a siren
if it detects tampering.
E39 interiors have a unique character, with a combination
of
sporty features and innovativedesign. All body versions were
made in a wide choice of interior and exterior colors. New col-
ors with matching leather or leatherette upholstery were intro-
duced for each model year.
Driving
comfort is enhanced by power steering, tilt steering
wheel, height-adjustable front seats, and electrically adjust-
able and heated rear-view mirrors. Inside the car there are
reading lights at four seating positions.

Door windows1
Window motor limit stop function
If repeated window activation (upldown cycles) exceeds one
minute, the
GM Ill deactivates the internal relays and disre-
gards any further
upldown requests. The GM Ill provides mo-
tor activation after a short duration but not for the full one
minute monitoring cycle.
The
GM Ill monitors the number of times a window motor is
activated. It counts each cycle and stores the number in
memory. Afler the stop function limit is reached and the win-
dow motor is deactivated, the
GM Ill slowly reverses the
stored count of activation until the stored number equals
0,
thus allowing the window motor to cool down.
WARNING-
* Always wear hand and eye protection when working with
brolen glass.
If a window is brolen, all of the glass bits should be
vacuumed out of the door cavity. Use a blunt
so-ewdi-iv-
er to clean out any remaining glass pieces from the
window guide rails.
When servicing the door windows, the harness con-
nector to the window regulator should always be dis-
connected to prevent pinching fingers in the moving
window mechanism.
Sedan and Sport Wagon doors are similar. Use the following
procedures for window service on these models.
WARNING-
E39 cars are iitted with side-impact airbags in the front
doors. Some are equipped with
airbags in the rear doors
as well. When
servicing the door windows on cars with
side-impact airbags, always disconnect the negative
(-)
battery cable. See 721 Airbag System (SRS) for cau-
tions and procedures relating to the
airbag system.
* Prior to disconnecting the battery, read the battery dis-
connection cautionsgiven
001 General Warnings and
Cautions.
