Towing
The cars covered by this manual should be towed with a tow
truck using wheel lift or flat bed equipment. Do not tow the car
on all four wheels except
forvery short distances to move it to
a safe place.
CA U JION-
Do not tow with sling-type equipment The front spoilers and
b~m~er covers may sustain damage.
4 To access threaded towing eye socltet, pry open trim on front
or rear bumper.
NOJE-
A towing eye is provided in the luggage compartment tool lcit.
The towing eye can be screwed into the front or rear bumper.
4 Install towing eye into threaded hole.
- Standard transmission: Do not tow with rear wheels on
ground unless absolutely necessary.
- Automatic transmission: Have rear wheels placed on dollies,
or use flat bed truck. Use towing eye for winching vehicle on
flat bed.
CAUTION-
Automatic transmission fluid (ATF) does not circulate when
I the car is towed. Severe transmission damage may result.
NOTE-
Be sure transrnission fluid has been topped off before
starting tow.
Always tow car with transrnission lever in
N (neutral).
. ATF draining and filling is covered in 240 Automatic
Transmission.
Be sure to read the filling and draining pro.
cedure, as special service equipment is required to
checlc
the fluid level.

I Radiator and Cooling System
Mechanical thermostat
(M52 engine)
4 The mechanical thermostat relies on coolant temperature to
operate. While coolant is cold, it remains closed, and circu-
lating coolant bypasses the radiator for rapid engine warm
up. At higher coolant temperature, the thermostat progres-
sively opens to allow coolant flow through the radiator, thus
controlling engine temperature. Port
A restricts coolant flow
from radiator, and port
B restricts coolant flow to radiator.
Electrically heated thermostat
4 The electrically heated thermostat is DME map-controlled.
The engine control module (ECM) activates the thermostat to
maintain engine coolant temperature within a narrow range.
In case of failure of the electronics, the mechanical function of
the thermostat acts as a fail-safe.
Radiator and expansion tank
The radiator is a crossflow design. An expansion tank pro-
vides for coolant expansion at higher temperatures and easy
monitoring of the coolant level.
On cars with automatic transmission, ATF is circulated
through an additional heat exchanger (ATF cooler).
Mechanical cooling fan with viscous clutch
The mechanical cooling fan is belt-driven via a viscous fluid
coupling (clutch) attached to the front of the coolant pump.
The fan clutch controls the speed of the fan based on the tem-
perature of the air flowing through the radiator core.
Electric (auxiliary) cooling fan
The electric cooling fan is mounted on the bumper side of the
radiator.
In models manufactured up to
911 998 (M52 or 1997 M62 en-
gine), the electric cooling fan is controlled by a dual tempera-
ture fan switch mounted in the side of the radiator.

With its traditional styling features, such as the ltidney grille.
circular headlights behind a glass cover (for reasons of
streamlining), and the
"kiclt" in the rear most roof pillar (C-pil-
lar), the E39 can be immediately recognized as a BMW.
The BMW 5 Series chassis is a unibody design constructed of
high strength steel. Attaching parts, such as the front fenders,
rear quarter panels, doors,
trunk lid and hood are also con-
structed of
steel.
Computer aided design (CAD) techniques have been used in
refining the
E39 body to reduce vehicle weight while retaining
strength and increasing torsional rigidity. For good handling
purposes, the more rigid the structure the more precisely the
suspension can operate.
Wind resistance
Windows bonded flush to the body and the guided flow of
cooling air into the engine compartment provide the
carwith a
good coefficient of drag (Cd).
E39 cars have been designed
for balanced aerodynamics but not necessarily an extremely
low Cd. See table below.
Windshield wipers are designed for effectiveness at speeds
up to and beyond 200
ltph (124 mph).
Coefficient of aerodynamic drag (Cd)
6-cylinder sedan 0.30
V-8 sedan 0.31
6-cylinder Sport Wagon 0.31
V-8 Sport Wagon 0.33
Fenders
The exterior panels are corrosion-resistant zinc coated (gal-
vanized) steel. The front fenders are bolted on. For front fend-
er replacement information, see
410 Fenders, Engine
Hood.

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.

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
