Body-General
SAFETY AND SECURITY FEATURES
A number of new or improved safety and security features are
incorporated in
E39 cars.
Safety cage
4 The body safety cage is a continuation of an established
BMW concept for passenger protection. Tubular impact
structures built into the body provide protection against pas-
senger injury during front or rear impacts.
Door locks and door handles
4 The door handles allow easy door opening, but are secure in
accidents.
Electrical components in the locks are fully encapsulated and
cannot be picked easily. The door handles, latches and
loclc
assemblies offer reliability and security against theft.
Door position and
loclc condition are detected by hall sensors.
Roof padding
In addition to the side and head protection airbags, there is
supplementary padding at the roof pillars and along the roof
above the doors. This is positioned to present energy absorb-
ing
surlaces to passengers thrown around by side impact
forces.
Seat belts
Each front seat belt assembly has a height-adjustable anchor
at the 8-pillar.
An automatic pyrotechnic (explosive charge) tensioner tight-
ens the front belt at the buckle upon impact, snugging up lap
and shoulder segments of the belt. The tensioners are de-
signed to automatically tension the belts by about
2 inches
(55 mm) in the event ofa collision.
A force limiter puts an upper limit on the amount of iorce each
belt can exert on the passenger.

Body-General
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.

Instrument cluster
Instrument cluster uses large easy-to-read analog instru-
ments and is removable as a unit without removing the dash-
board. On-board computer and Check Control functions are
integrated into the instrument cluster displays.
Service Interval Display
Service Interval Display calculates vehicle service needs
based on current driving patterns, and indicates to the driver
when the car requires
service
On-board navigation
An integrated on-board navigation system, based on Global
Positioning System (GPS) technology, is optionally available
on
E39 cars. When installed, a multifunction monitor is includ-
ed in the center of the dash above the radio. in addition to dis-
playing navigation system information, this monitor accesses
On-Board Computerfunctions, audiosystem controls, mobile
phone dialling and memory, and automatic ventilation.
Park Distance Control (PDC)
Park Distance Control (PDC) is an optional system which
uses ultrasonic sensors in the rear bumper trim to warn the
driver of approaching too close to obstacles when parlting.
Central body electronics
E39 vehicles are equipped with an integrated complex of
electronic modules connected mostly via K-Bus. This system,
called central body electronics (ZKE
Ill), is primarily con-
trolled by the general module (GM
Ill). An overview of ZKE Ill
functions is found in 600 Electrical System-General. Details
of ZKE
Ill functioning is in the following repair groups:
- 512 Door Windows
* 515 Central Locking and Aniti-Theft
520 Seats
a 540 Sunroof
611 Wipers and Washers
620 Instruments
