4 Remove plastic cover from lower trunlc lock. Loosen lock
bolts (arrows) until lock assembly can be moved.
CAUTION-
Before locking trunklid, check that trunk lid is not able to dam-
age the body or rear window.
4 Carefully close trunk lid and check side gaps (arrows). Min-
imum gap is 0.5 mm (0.02 in).
Adjust to fit side body panels.
Open trunlc lid.
Be careful not to alter adjustments.
Tighten lower trunlc lock fasteners.
Close trunk lid and check adjustments.
Repeat process if necessary.
- Close trunk lid. Measure gap between trunlc lid and lower
body panel.
Position lower section of rear trunlc lid
lock higher or lower
so that a
ciao of 5.0 mm (0.04 in) exists between trunlc lid
and
lowe;body panel. '
Check adjustment and repeat if necessary,
4 Screw out detent buffers (arrow) until left and right sides of
trunk lid rest against detent buffers with lid closed.

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.

Sunroof
Sunroof with glass roof panel, adjusting - -
< Slide sunroof liner back into roof cavity until approx. 70 mm
(2.75 in) is exposed.
Raise glass sunroof panel to vent position to expose rubber
gaiter (arrow).
- Working from center section of gaiter (arrow), carefully pull
gaiter off slotted mounting on sunroof glass panel.
CA UTIOW-
The gaiters tear easik
* Do not attempt to remove gaiters from lower edge of
sliding mechanism.
- With gaiters removed, three adjusting screws are visible at
front and rear of panel.
4 Sunroof panel is retained by three Torx screws (arrows) on
each side. To adjust sunroof height:
Loosen Torx screws until sunroof can just be moved.
- Push sunroof panel forward.
Push sunroof panel up or down until correct height is
achieved.
Reinstall sunroof gaiter.

I Airbag System (SRS)
Two-stage airbag (MRS Ill)
Beginning with 2000 model year (911 999 production) the front
airbags were changed to a two-stage style airbag. This en-
sures that the force of
airbag inflation is not greater than nec-
essary to provide
protection. The airbags are designed to
Drovide "soit" de~lovment if the acceleration sensor detects a
iow-speed impact, and "hard deployment in higher speed im-
pacts.
NOTE-
A two-stage passenger airbag was used on cars built be-
tween
9/1998 and 3/1999. This pre-smart technology airbag
used two ignition stages. Stage one is designed to ignite first
during an impact. Stage two ignites after a timed period, as
programmed in the MRS
I1 control module.
Airbag indicator light
The MRS control module detects and stores system status
The
airbag indicator light in the instrument cluster displays
the status of the
airbag system when the ignition key is in "ac-
cessory" or
ON positions.
System normal: lndicator light comes on briefly, then goes
out.
- System malfunction: lndicator light fails to come on.
System malfunction: lndicator light comes on briefly, goes
out and lights up again.
The
airbag indicator light also comes on if the seat belt pyro-
technic tensioners have been triggered.

On-Board Diagnostics
Catalyst monitoring. Thisstrategy monitors the outputofthe
precatalyst and post-catalyst oxygen sensors, comparing the
oxygen content going into the catalytic converter to the
oxygen leaving the converter.
The diagnostic executive
lknows that most of the oxygen
should be used up during the oxidation phase. If it detects
higherthan programmed values, afault is set and the MIL
illuminates.
Misfire detection. This strategy monitors crankshaft speed
fluctuations and determines if an enoine misfire occurs bv
monitoring variations in speed between each crankshaft
sensortrigger point. This strategy is so finely tuned that it can
determine the severity of the misfire.
The system determines
if a misfire is occurring, as well as
other pertinent misfire
information such as:
Specific
cylinder(s)
Severity of the misfire event
Emissions relevant or catalyst damaging
Misfire detection is an on-going monitoring process that is
only disabled under certain limited conditions.
Secondary air injection monitoring. Secondary air
injection is used to reduce HC and CO emissions during
engine warm up. Immediately following a cold engine start
(-1 0" to 40°C), fresh air (and therefore oxygen) is pumped
directly into the exhaust
manifold. By injecting additional
oxygen into the exhaust manifold, catalyst warm-up time is
reduced.
Secondary air system components are:
Electric air injection pump
* Electric pump relay
* Non-return valve
Vacuum
I vent valve
- Stainless steel air injection pipes
Vacuum reservoir
The secondary air system is monitored via the use
of the pre-
catalyst oxygen sensors. Once the air pump is active and air
is injected into the system, the signal at the oxygen sensor
reflects a lean condition. If the oxygen sensor signal does not
change, a fault is set and the faulty
bank(s) identified. If after
completing the next cold startafault is again present, the MIL
illuminates.
