Bumpers
The front and rear bumpers are clad in high quality
deform-
able plastic and, at solid barrier impact speeds of 4 kph (2.5
mph), provide protection with virtually no damage to the
bumper
orthe vehicle. In addition to hydraulic dampeners.
which absorb the initial impact energy, these bumpers are
backed by compressible tubes. These deform in a controlled
manner at impact speeds greaterthan that
forwhich bumpers
and hydraulic dampeners are designed. This helps avoid ex-
pensive damage to the body at impact speeds up to 14 kph (9
mph).
The E39 Sport Wagon was introduced to the US market in
911 998 (model year 1999). It shares many components with
the E39 sedan and is identical to it from the B-pillar forward.
US
marltet 5 Series Sport Wagons are available in two vari-
ants:
6-cylinder
(5251, 528i) powered by the 2.8 liter M52 TU en-
gine (1 999) or the 2.5 liter M54 engine (2000 and later)
* V-8 (540i) powered by the 4.4 liter M62 TU engine
The wheelbase of the Sport Wagon is the same as the sedan.
Howeverthe body is 30
mm (1.2 in) longer and 10 mm (0.4 in)
higher.
The Sport Wagon rear suspension was redesigned to elimi-
nates the upper rear spring strut mounting on the E39 sedan.
The use of separate coil springs and
shoclc absorbers results
in a flat, wide floor in the cargo area. See
300 Suspension,
Steering and Brakes-General.
The self-leveling air spring suspension system (electronic
height control or EHC) is standard on Sport Wagon V-8 mod-
els and optional on 6-cylinder models.

Rear wiper system
The rear wiper assembly on the E39 Sport Wagon is a self-
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.

Operation of rear window washer
The wiper system automatically controls the following safety
and convenience features:
* Wiper interrupted when rear glass is opened
Wiper interrupted if wiper arm is blocked
Continuous wiping when vehicle is shifled into reverse
Antenna and sound system

The radio amplifier and CD changer are behind the side
ac-
cess panels in the cargo compartment:
CD changer on lefl side

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.

Seats
4 Anatomically correct seats are constructed from polyure-
10 way seat adjustment thane foam
containing areas or "zones" of different firmness.
They offer good lateral support without constricting the occu-
pant.
The seats have a passive internal ventilation system: Cylin-
drical cavities within the cushions and backrests generate a
pumping effect as the ride motions cause occupant motion.
This
helps remove moisture and feeds fresh air into the seats.
Other features of the seating system:
The seat bases have steel springs for added support and
strength.
The seat control switches are along the outside edge of
the
seat.
Heated seats are an option in all models
In cars equipped with seat position memory, three different
seat confiaurations can be memorized by the seat control
module(s): Seat memory coordinates with outside mirror
memory. These functions are controlled by the seat mem-
ory
module(s).
* For security reasons, the release lever to fold the rear seat
backrest forward is installed in the trunk.
Sport Wagon models: Rear seat
baclts are split 60140, with
the center armrest on the left seat back.
The center armrest incorporates a non adjustable head-
rest. When folded down, the armrest opens out with
cup-
holders and a storage compartment. See 520 Seats for
more details.
instruments and controls
Everything in the interior passengercompartment essential to
the driver is logically grouped and easy to reach. All instru-
ments and controls have been arranged ergonomically and
are fully integrated into the overall design of the vehicle.
Tilt-telescopic steering wheel has
30 mm (1.2 in) of vertical
and longitudinal adjustment.
Multifunction steering wheel contains two
ltey pads con-
taining controls for the sound system, telephone and
cruise control.
Padded dashboard houses the instrument cluster and the
ventilation and heating system.

ELECTRONIC ~MMOBILIZATION (EWS)
E39 cars are equipped with a passive theft-prevention sys-
tem. The Electronic Immobilization System (EWS) makes it
impossible to
startthe engine using any means other than the
special lkeys furnished with the vehicle.
NOTE-
Replacement EWS control modules or DME control modules
must be electronically aligned to each before the vehicle will
start. This requires the use of the BMW Service Tester
(DIS-
plus, GT1, or MoDiC). Without alignment, the engine will not
crank (for example: swapping a
known good DME control
module into another vehicle for test purposes will result in a
no crank situation).
In the EWS system, the ignition key is embedded with
acom-
puter chip (EEPROM) and coded. The key communicates
with the vehicle using a transponder in the lkey and a ring an-
tenna surrounding the steering lock cylinder. Up to
6 replace-
ment keys are permissible. Only an authorized
BMW dealer
can provide replacement keys.
