l~entral Locking and Anti-Theft
ANTI-THEFT SYSTEM (DWA)
When the anti-then system (DWA) is armed, the doors, hood,
windows, trunk lid or tailgate are monitored against forcible
entry by switches and sensors. The vehicle is protected
against being jacked up or towed away by a tilt sensor.
The control electronics for DWA are integrated in the General
Module (GM). In addition to the control electronics, the sys-
tem includes the following components.
* DWA horn
DWA LED indicator
- Tilt sensor
- Monitoring switches and sensors
The system can be armed or disarmed from the driver's door
lock,
trunklid lock, tailgate lockorthe remote transmitter (FZV
Itey). When armed, the alarm horn
soundsfor30seconds and
the low beam headlights and turn signals flash for
5 minutes.
The electronic immobilizer (EWS) is also activated when
DWA is activated.
The alarm is switched off immediately if key is inserted in door
loclt or FZV key button is used.
DWA LED Status
The DWA status LED is located in the rear view mirror (ar-
row). When DWA is armed, the LED flashes slowly to indi-
cate armed status.
The LED and exterior lights flash once and the alarm horn
sounds when the system is successfully armed ordisarmed.
The LED will continue to flash slowly denoting the armed sta-
tus. If any monitored input is not closed when the system is
armed, the LED will flash rapidly for
10 seconds to indicate
the fault.
Tilt sensor
-
4 The tilt sensor, located on the left side of trunlt or cargo com- -
partment, consists of a conductive liquid chamber, a proces-
sor board and metal probes. The probes are submersed in
the liquid and produce a resistance value dependent on the
tilt of the sensor (angle of the vehicle). This resistance be-
comes the reference value when the DWA system is armed.

l Seats
This repair group covers removal and installation of the front
and rear seat.
SeatIMirrorlSteering Column Memory
< The basic features of seaffmirrorlsteering column operation,
including memory positions are integrated into the
ZKE Ill
system. Driver adjustment positions can be memorized and
stored for three different
users.The seat control module is in-
tegral with the seat and mirror switches. The seat control
module stores seat memory position via the "ripple" counter
module.
NOTE-
Passenger seat on sedan models uses a simple control cir-
cuit and do not include a memory module or on-board diag-
nostics.
Seat memory position, setting
With the transmission range selector in "P and the mirror
change over switched in the left position, switch the ignition
on and press the
"M" on the memory switch.
Press one of the three position switches
(1, 2 or 3) within
the
7 second memory period (memory indicator lamp will
illuminate for
7 seconds)
- The current positions of the mirrors, seat and steering col-
umn will now be stored in memory.
NOTE- Seat memory is held in an
EEPROM in the seat module and
is stored in memory before the
ZKE goes into its sleep mode.
If the battery is disconnected before the 16 minute sleep
mode activation, seat memorypositions are lost and repro-
gramming is required.

Sunroof
This repair group covers the slide-tilt sunroof assembly.
There are two types of sunroof panels available: steel
01
glass. Service procedures are different for each type.
Component locations, initialization, sunroof panel replace-
ment, and sunroof height adjustment are covered. Replace-
ment of the cable assembly or frame require that the
headliner be removed. Removal and repair of the sunroof as-
sembly and othercomponents inside the roof cavity is beyond
the scope of this manual.
When the sunroof is set to the vent position (rear of panel up),
the inside headliner moves rearward approximately
120 mm
(4.7 in) This provides cabin ventilation with less wind noise. A
water channel is incorporated into the sunroof assembly. It
automatically rises when the sunroof panel is in the vent posi-
tion and prevents water from entering the interior during brak-
ing.
Sunroof electronic controls, initializing
- Initialize the sunroof in the following situations:
Malfunctions
such as lack of one-touch function, lack of
comfort openinglclosing or lack of safety (anti-trapping)
features.
If sunroof motor has been removed and reinstalled.
If power supply to the sunroof has been interrupted.
If repairs have been performed on the slideltilt mechanism.
NOTE -
The initialization sequence is dependent on the software ver-
sion of
tlie sunroof module (in the sunroof drive unit).
I WARNING -
I There is no anti-trapping protection during initialization. I

Sunroof, adjusting
The sunroof is controlled by a set of cables that move the sun-
roof panel along guide rails when the motor is operated. The
sunroof can be adjusted without removing it from the car.
NOTE-
Be sure to check drains in front corners of sunroof carrier if
water is entering car through headliner.
- The sunroof panel should be adjusted under the following cir-
cumstances:
Sunroof misaligned with roof.
Sunroof does not close squarely.
* Wind noise at high speeds (sunroof closed).
Sunroof has been removed.
For correct sunroof alignment:
Sunroof must be fully closed.
Gap must be even all around edge of sunroof.
Front of sunroof must be flush to
1 mm (0.04 in.) below sur-
face of roof.
. Rear of sunroof must be flush to 1 mm (0.04) above sur-
face of roof.
NOTE-
Use a credit card to measure the gap. The card sllould insert
through the gap with equal resistance all around the perimeter.
Sunroof with steel roof panel, adjusting
- The headliner panel must be disengaged from the drive as-
sembly and moved rearward in order to access the roof panel
attaching screws.
CAUTIOI\C
Sunroof panel must never be moved to open position when . .
I the headliner is disenaaaed. 1
- Start with a fully closed roof panel.
- Remove drive motor access cover. See Sunroof motor, re-
placing.
Using hex key from tool kit, turn motor drive 90" counter-
clockwise.
Rear of sunroof panel will drop
2 to 3 mm (0.08 to 0.12 in).
This disengages headliner from sunroof panel.
- Push headliner panel rearward, exposing roof panel attach-
ing screws.
