BMW 3 (E46). Manual — part 185
For security reasons, the release
lever to fold the rear seat backrest
forward is installed in the trunk.
In Sport Wagon models: Rear seat
backs are split 60/40 with the
center arm rest on the left seat
back. The center arm rest
incorporates a non adjustable
headrest. When folded down, the
arm rest opens out with
cup-holders and a storage
compartment.

for more details.
Instruments and controls
Everything in the interior passenger
compartment essential to the driver is
logically grouped and easy to reach. All
instruments and controls have been
arranged ergonomically and are fully
integrated into the overall design of the
vehicle. The following features are
optional in some models.
Tilt-telescopic steering wheel has 30
mm (1.2 in.) of vertical and longitudinal
adjustment.
Multi-function steering wheel contains
two key pads containing controls for
the sound system, telephone and
cruise control.
Padded dashboard houses the
instrument cluster and the ventilation
and heating system.
Instrument cluster uses large
easy-to-read analog instruments and is
removable as a unit without removing
the dashboard. On-board computer
and Check Control functions are
integrated into the instrument cluster
displays.
Service Interval Display calculates
vehicle service needs, based on
current driving patterns, and indicates
to the driver when the car requires
service.
Integrated on-board navigation system,
based on Global Positioning System
(GPS) technology, is optionally
available on E46 cars. When installed,
a multi-function monitor is included in
the center of the dash above the radio.
In addition to displaying navigation
system information, this monitor
accesses to On-Board Computer
functions, audio system controls,
mobile phone dialling and memory,
and automatic ventilation.
Park Distance Control (PDC) is an
optional system which uses ultra-sonic
sensors in the rear bumper trim to warn
the driver of approaching too close to
obstacles when parking.
Central Body Electronics (ZKE
V)
E46 cars are equipped with a
sophisticated centralized body
electric/electronics plan. Central Body
Electronics (ZKE V) is self-diagnostic
and incorporates many functions into a
single control module. The
consolidation of several systems into a
single control module minimizes power
requirements and the incorporation of
the diagnostic link results in more
efficient and accurate troubleshooting.
ZKE V directly controls the following
functions:
Windshield wiper/washer system,
with optional Rain Sensor
Interface. See
611 Wipers and
Washers
.
Central locking with power trunk
release. See
515 Central
Locking and Anti-theft
.
Keyless entry (FZV)
Power window control. See
512
Door Windows
.
Car/key memory
Interior lighting
Alarm system (DWA)
Electronic consumer sleep mode.
See
600 Electrical System–
General
.
Other functions not directly controlled
by ZKE V but interconnected:
Rain sensor (AIC)
Sunroof operation. See
540
Sunroof
.
Seat memory. See
520 Seats
.
Outside rear-view mirror control
and heating
Windshield washer jet heating
ZKE V Diagnostic Trouble Codes
(DTCs) are accessible electronically
through the data-link connector (DLC).
See
610 Electrical Component
Locations
.
Note:
All 1999 models and cars
produced through June 2000 are
equipped with the DLC socket in
the rear right corner of the engine
compartment.
In cars produced after June 2000,
the DLC socket in the engine
compartment has been
discontinued. All scan tool codes
can now be accessed through the
OBD II interface socket on the
driver's side of the dashboard, left
and below the instrument cluster,
under a cover.
Heating and air conditioning
(IHKA)
The integrated heating and air
conditioning (IHKA) system uses an
extra large, infinitely variable radial
blower motor for good distribution of
air. Fresh air enters through the grille
below the engine hood and into the
passenger compartment via the
dashboard and footwell vents.
Repair information for the heating and
air conditioning system is covered in
640 Heating and Air Conditioning
.
