Trunk Lid, Tailgate
Rear window and tailgate, alignment
- Alignment procedures involve adjusting tailgate, window, and
spoiler to have equal space between
iefl and right sides and
to be flush with body. Measurement locations and specific di-
mensions are shown.
- If alignment has been disturbed during repair, adjust fit of tail-
gate to body. Then adjust fit of rear window to tailgate.
Clearance of the rear window is adjusted by adding or re-
moving shims between hinge bracket and rear window
(maximum of three shims).
Adjust spoiler gap to body last.
Height of spoiler is set by alignment of the rear tailgate.
Gap of spoiler to body is set by adjusting spoiler attach-
ment fasteners.
- Lateral and vertical alignment of the window and tailgate is
done using hinge bolts. Fine adjustment of the tailgate to the
body is made using rubber stop buffers and latch assembly.
Spoiler gap specification Rear spoiler to roof 4.25
- 5 mm
(0.167 - 0.197 in)
Max. deviation from parallel 0.5
mm (0.019 in)
Tailgate alignment, preliminary work
- Open rear window and tailgate.
< Remove lower sill trim panel fasteners covers (arrows) and
fasteners.

I Door Windows
/ Anti-trap strip
Power window motors
The window motors are mounted on cable regulators. The
window motor control circuit consists of two wires for operat-
ing the motor in both directions.
The motors are activated by relays in the GM
Ill. The relays
provide either power or ground depending on the direction of
window travel. The GM
Ill controls the polarity based on a re-
quest to run the window from a window switch or a conve-
nience
openinglclosing signal.
Convenience openinglclosing
The GM Iii provides the convenience openlclose feature, pro-
viding control of the power windows (and sunroof) from out-
side the vehicle with the key in the driver's door lock. The FZV
(remote key) provides the same function for window opening
only.
Anti-trap protection is active during convenience closing from
the driver's door lock.
If the GM receives a request to operate convenience closing
or opening for more than
110 seconds, the function is deacti-
vated and a
fault code is stored.
Window anti-trap protection
4 A rubber pressure guard is located at the top edge of each
door frame. It consists of two contact strips that close when
subjected to pressure. When the contact strip closes (for ex-
ample, a hand is trapped between the top of the window and
the door frame), an anti-trap signal is sent to the GM
Ill. The
window immediately (within
10 milliseconds) reverses direc-
tion. This feature does not require
initialization.
The E39 pressure sensor finger guard has a resistance of 3
Kw and it is monitored for open circuits. When pressed, the
monitored resistance changes to
< 1 Kw. if anti-trap protection
becomes faulty the one touch window closing will not func-
tion.
Window anti-trap protection is
only active in the one touch
and convenience close modes of operation. If the window
switch is pulled and held, anti-trap protection will not function.
The anti-trap contact strip has a resistance of
1.2 K Ohm and
it is monitored for open circuits. Faults with the anti-trap sys-
tem will cancel the one touch feature requiring the window
switch be held to close the window.

Central Locking and Anti-Theft
DWA alarm
The DWA alarm system is
armedldisarmed when thevehicle
is locked / unlocked from either the door or trunk.
Convenience closing
I opening
The windows and sun roof can be closed or opened by hold-
ing the key in the
loclc I unlock position.
Crash sensor
The crash sensor is located in the left front
kick panel. It func-
tions by unlocking all doors in the event of an accident.
NOTE-
Continuous and repeated locliing / unlocking may cause
timedarrest of
the locliing system. When activated, the timed
arrest lasts for two minutes. The timed arrest does not affect
the crash sensor
unlocliing the doors in case of an accident.
Door locks
The driver's door lock location is the only point outside of the
vehicle where the ltey can mechanically control all of the cen-
tral locking system functions.
4 Door key positions for electrical / manual loclting and
unlocking are:
1. Manual unlock
2. Unlock, DWA disarmed, convenience open
(hold until activated)
3. Neutral position
4. Lock, DWA armed, convenience closing
(hold until activated)
5. Manual lock
The door lock actuators are sealed. self contained units with
no replaceable parts. The
actuators use Hall effect sensors in
place of pin contacts and microswitches to provide DOOR
OPEN
I DOOR CLOSED status signal. Each door lock button
only affects the actuator it controls. There is no effect on the
other doors.
An automatic locking feature activates door locks when a
road speed signal of 4 mph is detected via the K-Bus. The fac-
tory default coding for this feature is OFF, but can be coded
ON for individual users with the Key Memoryfunction. See
Car Memory
1 Key Memory later in this section.

- The trunk can be opened from this remote release when the
doors are locked from the central locking button. The
trunk
remote button is disabled when the trunkis loclted in the valet
position or when a speed signal of
4 mph is present at the
GM.
Remote entry (FZV)
< The €39 remote (keyless) entry system (FZV) uses a tiny ra-
dio transmitter in the vehicle key to
lock and unlock the doors
and the trunk by remote control. There are a number of other
features incorporated in FZV:
Locltinglunloclting of fuel filler lid
Selective unlocking of driver's door (as with key in lock)
Armingldisarming of DWA alarm system
Remote unlocking of
trunk lid or tailgate
Comfort opening of windows and sunroof
* Interior lighting activation
Panic mode alarm activation
* Models to 1999: Key incorporates LED. LED informs oper-
ator that an FZV signal is being transmitted. LED is also
useful indicator of key initialization status and lkey self-test.
Keys delivered with four different colored labels. This is
helpful to differentiate FZV keys during initialization,
pre.
venting possibility of misassigning key ID which would
change coded Key Memory functions.

/Central Locking and Anti-Theft
The General Module (GM) is connected to the FZV receiver
module (in left rear roof pillar) via K-Bus. Locking and unlock-
ing of doors, trunk or tailgate and convenience closing is car-
ried out by the GM subsystem controlling the door lock,
window and sunroof modules.
The accompanying schematic, Remote entry
(FZV) inputs
and outputs, illustrates the GM remote entry subsystem.

antenna while ltey is in ignition switch. There is no need to re-
place ltey battery.
