SPARK PLUG
DESCRIPTION - STANDARD 2.4L
All engines use resistor spark plugs. They have
resistance values ranging from 6,000 to 20,000 ohms
when checked with at least a 1000 volt spark plug
tester.
Do not use an ohm meter to check the resis-
tance of the spark plugs. This will give an inac-
curate reading.
Refer to the Specifications section for gap and type
of spark plug.
DESCRIPTION - PLATINUM 3.3/3.8L
These engines utilize platinum spark plugs. Refer
to the maintenance schedule.
All engines use resistor spark plugs. They have
resistance values ranging from 6,000 to 20,000 ohms
when checked with at least a 1000 volt spark plug
tester.
Do not use an ohm meter to check the resis-
tance of the spark plugs. This will give an inac-
curate reading.
The spark plugs are double platinum and have a
recommended service life of 100,000 miles for normal
driving conditions per schedule A in this manual. The
spark plugs have a recommended service life of
75,000 miles for severe driving conditions per sched-
ule B in this manual. A thin platinum pad is welded
to both electrode ends as show in (Fig. 14). Extreme
care must be used to prevent spark plug cross
threading, mis-gaping and ceramic insulator damage
during plug removal and installation.

WARNING: DO NOT CONNECT THE BATTERY NEG-

RESTRAINTS, DIAGNOSIS AND TESTING - AIRBAG
SYSTEM FIRST.
PASSENGER AIRBAG
DESCRIPTION
WARNING: NEVER DISASSEMBLE THE PASSEN-
GER AIRBAG, THE PASSENGER AIRBAG HAS NO
SERVICEABLE PARTS.
The Passenger Airbag is located beneath the
instrument panel and pad assembly. The airbag is
mounted to the back side of the instrument panel
reinforcement.
The instrument panel top pad is the most visible
part of the passenger airbag system. Located under
the instrument panel top pad are the airbag door, the
passenger airbag cushion and the airbag cushion
supporting components.
The passenger airbag includes a magnesium hous-
ing within which the cushion and inflator are
mounted and sealed.
Following a passenger airbag deployment, the pas-
senger airbag and the instrument panel must be
replaced. The passenger airbag cannot be repaired,
and must be replaced if deployed or damaged in any
way.
OPERATION
The passenger airbag is equipped with two infla-
tors, each with three levels of pressure output. The
inflators seal the hole in the airbag cushion so it can
discharge the gas it produces directly into the cush-
ion when supplied with the proper electrical signal.
Following an airbag deployment, the airbag cushion
quickly deflates by venting this gas through the
cushion material towards the instrument panel.
The passenger airbag is secured with screws to the
instrument panel beneath the instrument panel top
pad and above the glove box opening. The instrumentpanel top pad above the glove box opening conceals
the airbag door and a predetermined hinge line
beneath its decorative cover. Upon airbag deploy-
ment, the top pad will bend at the hinge line and the
door will fold back out of the way onto the top of the
instrument panel.
WHEN THE FRONT AIRBAG SYSTEM IS
DEPLOYED BECAUSE OF A COLLISION, THE
FOLLOWING MUST BE REPLACED:
²COMPLETE STEERING COLUMN ASSEMBLY
²LOWER STEERING COUPLER
²STEERING WHEEL
²STEERING COLUMN CLOCK SPRING
²DRIVER AIRBAG COVER/HORN SWITCH
²DRIVER AIRBAG
²PASSENGER AIRBAG
²UPPER INSTRUMENT PANEL WITH PAD
CARE OF UNDEPLOYED AIRBAGS
Airbags must be stored in their original special
container until used for service. At no time should a
source of electricity be permitted near the inflator on
the back of an airbag. When carrying or handling an
undeployed airbag, the trim side of the airbag should
be pointing away from the body to minimize possibil-
ity of injury if accidental deployment occurs. Do not
place undeployed airbag face down on a solid surface,
the airbag will propel into the air if accidental
deployment occurs.
STANDARD PROCEDURE - DEPLOYED
PASSENGER AIRBAG CLEAN UP
Roll or fold the passenger airbag towards the
instrument panel surface and close the door over the
folded bag. Then tape the door shut.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well. If
HVAC was in RECIRC mode at time of airbag
deployment, operate HVAC blower on low speed/heat
and vacuum powder residue expelled from the heat
outlets. Multiple vacuum cleaning may be necessary
to decontaminate the interior of the vehicle.
SERVICE OF DEPLOYED AIRBAG
If a Passenger Airbag has been deployed, but not
due to a collision, replace the following:
²Passenger Airbag
²Upper instrument panel with pad
The component above must be replaced because
they cannot be reused. Inspect the heat duct near the
passenger airbag for any damage replace as neces-
sary. Replace any other passenger airbag system
components if damaged.
