2001 MODEL YEAR CHANGES

2001 model year changes
Fog lights
New circular fog lights with convex plastic lens-
es are tucked neatly into the corners of the new
front air dam. The new lights use an H8 12V
35 W halogen bulb.
Park Distance Control
The 2001 E39 will have Front and Rear PDC available as an option. The system operates
just as the E38 and E53 with the same system. The vehicle is fitted with a PDC switch
located on the SZM. Activation is automatic with reverse gear engagement, but may be
deactivated with the switch. The switch may also be used to activate the system. Criteria
for operation remain unchanged from previous systems.

2001 model year changes
Head and Tail Lights
The head and tail lights of the 2001 E39 have received a new look, utilizing optical wave
guide technology. The wave guides are an innovation that are not only aesthetically
pleasing, but also enhance safety.
Head Lights
The front headlights have been completely redesigned, however they fit into the existing
body without any sheet metal changes. The high and low beam headlights are free-form
reflectors and no longer use the glass lenses. The turn signal has been given its own
circular lens next to the low beam.

2001 model year changes
The parking light and side marker use the optical wave guide technology. Clear rings
surround the high and low beam reflectors. The rings are illuminated by a light source
module similar to the ones used in the Visual Entry Aid system. Output voltage for the light
source module comes from the parking lamp final stage of the LCM III. There is one light
source module located at the back of the head light housing between the high and low
beam headlights. The side marker for US models also has an additional wave guide con-
ductor for illumination.
Third generation Xenon headlights manufactured by Hella are standard equipment on V-8
powered cars and available as an option on the 6 cylinder models. All xenon equipped
vehicles also use LWR automatic headlight adjustment to maintain the vertical adjustment
of the headlights at any vehicle load. (
Refer to the 1999 Model Update training for details of sys-
tem operation)

Tail lights
The rear light housings have also been modi-
fied for 2001. No body changes were neces-
sary.
The LED illuminated tail lights provide an excit-
ing fresh look to the part of a 5 Series most dri-
vers on the road are familiar with.
Each tail light housing contains 4 wave guide
assemblies. At either end of the wave guides
is a printed circuit board with 4 LEDs. The
LEDs provide the illumination for the tail light
only. US models use an additional 4 LEDs in
the corner of the housing as a side marker.
On Sport Wagon models, the tail light assem-
bly is two pieces. In this case there continue
to be only two sets of LEDs; one supplying
light for each half of the housing. US models
also have two LEDs for the side marker.
The advantage to using LEDs is the longer life
span as well as lower power consumption.
The function of the LCM III remains unchanged from the previous year with the exception
that because of the LED illuminated tail lights, there is no tail light monitoring function. The
LCM III module has been updated for the new lighting features of the 2001 E39. All
replacement LCM modules will supercede to this version in the parts system and it can be
used on earlier vehicles.
