Automatic shiftlock, checking function (automatic transmission)
The automatic shiftlock uses an electric solenoid to lock the
selector lever in Park or Neutral. Depressing the foot bralte
with the ignition on energizes the solenoid, allowing the lever
to be moved into a drive gear. The solenoid is energized only
when the engine speed is below 2,500 rpm and the vehicle
speed is below
3 mph (5 kph). The solenoid is mounted in the
right side of the selector lever housing.

Shift interlock, checking function
(automatic transmission)
4 The shift interlock uses a cable between the ignition switch
and the shift lever to lock the shift lever in the park position
when the key is in the off position or removed. This feature
also prevents the key
from being removed from the ignition
lock until the selector lever is in Park.
Shift selector lever to Park position and turn ignition key to
the off position.
Remove ignition key. Checlc that selector lever cannot be
shifted out of Park position.
Turn ignition lkey on and depress
brake pedal. Checlc that
selector lever moves freely from gear to gear.
With selector lever in a gear position other than Park, at-
tempt to turn lkey to off position and remove. Key should not
go into off position.
If any faults are found check cable for lkinks and
check
cable attachment points for damage or faults.
NOTE-
* It must only be possible to remove ignition ley with
selector lever
in Park position.
* Do not link shift interlocl( cable.
Shift interlock repair is covered
in 320 Steering and
Wheel Alignment.

lnterior trim repairs
lnterior trim and finish panels are clipped or screwed into
place. Many of the trim retaining clips are designed
to be used
only once. When removing trim that is held in place with clips,
it is a good idea to have spare clips on hand before beginning
the job.
WARNING-
Special precautions must be observed when servicing the
BMWSupplementai Restraint System (SRS). Serious inju-
ry may result if system service is attempted by persons un-
familiar with the BMW
SRS and its approved service
procedures. BMW
speciiies that all inspection and service
should be performed by an authorized BMW
dealer.
Before performing any work involving airbags, discon-
nect the negative
() battery cable. See 721 Airbag
System (SRS).
Airbags contain a back-uppowersupply within the SRS
control module. A
5 second discharge period should be
allowed after the battery cable has been disconnected.
CAUTION-
* When working on electrical switclies or lights, always dis-
connect the negative
(-) cable from the battery and insu-
late the cable end to prevent accidental reconnection.
a Prior to disconnecting the battery, read the battery dis-
connection cautions given in
W1 General Warnings
and Cautions.
To prevent marring the trim when working on interior
components, work with plastic prying
tools or wrap the
tips of screwdrivers and pliers with tape before prying
