²RETRAIN TIRE SENSORS?- This program-
mable feature only applies to vehicles equipped with
the optional tire pressure monitoring system. The
options include Yes and No. The default is No. When
Yes is selected and the menu button is depressed, the
EVIC will enter the training mode starting with the
left front tire.
²EASY EXIT SEAT?- This programmable fea-
ture only applies to vehicles equipped with the
optional memory system. The options include Yes and
No. The default is No. When Yes is selected, the
driver seat moves rearward about 55 millimeters
(two inches) or to the farthest rearward position,
whichever comes first, when the key is removed from
the ignition switch lock cylinder. This provides addi-
tional ease for exiting from the vehicle. The seat will
automatically return to the memory system setting
position when the Driver 1 or Driver 2 button of the
memory switch on the door panel is depressed or, if
theREMOTE LINKED TO MEMORYprogramma-
ble feature is enabled, when the RKE Unlock button
is depressed. While not automatic, an easy entry fea-
ture can be obtained by enabling theEASY EXIT
SEATfeature and disabling theREMOTE LINKED
TO MEMORYfeature. Then theEASY EXIT SEAT
feature will move the seat back, but the RKE unlock
event will not reposition the seat. Thus, the seat
remains positioned for easy entry, and the memory
switch on the door panel can be depressed after
entering the vehicle to return the seat to the desired
memory position.
STANDARD PROCEDURE - COMPASS
DEMAGNETIZING
A degaussing tool (Special Tool 6029) is used to
demagnetize, or degauss, the overhead console for-
ward mounting screw and the roof panel above the
overhead console. Equivalent units must be rated as
continuous duty for 110/115 volts and 60 Hz. They
must also have a field strength of over 350 gauss at 7
millimeters (0.25 inch) beyond the tip of the probe.
To demagnetize the roof panel and the overhead
console forward mounting screw, proceed as follows:
(1) Be certain that the ignition switch is in the Off
position, before you begin the demagnetizing proce-
dure.
(2) Connect the degaussing tool to an electrical
outlet, while keeping the tool at least 61 centimeters
(2 feet) away from the compass unit.
(3) Slowly approach the head of the overhead con-
sole forward mounting screw with the degaussing
tool connected.
(4) Contact the head of the screw with the plastic
coated tip of the degaussing tool for about two sec-
onds.(5) With the degaussing tool still energized, slowly
back it away from the screw. When the tip of the tool
is at least 61 centimeters (2 feet) from the screw
head, disconnect the tool.
(6) Place a piece of paper approximately 22 by 28
centimeters (8.5 by 11 inches), oriented on the vehicle
lengthwise from front to rear, on the center line of
the roof at the windshield header (Fig. 3). The pur-
pose of the paper is to protect the roof panel from
scratches, and to define the area to be demagnetized.
(7) Connect the degaussing tool to an electrical
outlet, while keeping the tool at least 61 centimeters
(2 feet) away from the compass unit.
(8) Slowly approach the center line of the roof
panel at the windshield header, with the degaussing
tool connected.
(9) Contact the roof panel with the plastic coated
tip of the degaussing tool. Be sure that the template
is in place to avoid scratching the roof panel. Using a
slow, back-and-forth sweeping motion, and allowing
13 millimeters (0.50 inch) between passes, move the
tool at least 11 centimeters (4 inches) to each side of
the roof center line, and 28 centimeters (11 inches)
back from the windshield header.
(10) With the degaussing tool still energized,
slowly back it away from the roof panel. When the

PASSENGER AIRBAG
DESCRIPTION
The rearward facing surface of the instrument
panel top pad above the glove box is the most visible
part of the passenger airbag (Fig. 31). The passenger
airbag is located above the glove box opening in front
of the front seat passenger seating position within
the instrument panel. The stamped steel passenger
airbag door is secured on the back of the instrument
panel top pad armature between the two passenger
side panel outlets. A stamped metal reinforcement is
secured to the instrument panel top pad armature
near the upper edge of the passenger airbag door
opening, and helps to define a predetermined hinge
line beneath the decorative cover of the top pad. The
instrument panel passenger side bezel is secured to
the airbag door from behind with four screws.
Located behind the passenger airbag door within
the instrument panel is the passenger airbag unit.
The passenger airbag unit used in this model is a
multistage, Next Generation-type that complies with
revised federal airbag standards to deploy with less
force than those used in some prior models. The pas-
senger airbag unit consists of an extruded aluminum
housing, a molded plastic inner airbag cushion dust
cover, the airbag cushion, and the airbag inflator.
The airbag housing contains the airbag inflator,
while the inner dust cover contains the folded airbag
cushion. The dust cover completely encloses the air-
bag cushion and is permanently retained to the hous-
ing. The passenger airbag unit is secured with four
screws to the instrument panel structural duct. Con-cealed beneath the instrument panel top pad are the
passenger airbag door, the folded airbag cushion, the
airbag retainer or housing, and the airbag inflator.
The airbag cushion is constructed of a coated nylon
fabric. The airbag inflator is a dual-initiator, hybrid-
type unit that is secured to and sealed within the air-
bag housing. A short four-wire pigtail harness with a
keyed, yellow connector insulator connects the two
inflator initiators to the vehicle electrical system
through a dedicated take out and connector of the
instrument panel wire harness.
The passenger airbag cannot be repaired, and must
be replaced if deployed, faulty, or in any way dam-
aged. The passenger airbag cannot be repaired, and
must be replaced if faulty or in any way damaged.
The passenger airbag door is serviced only as a unit
with the instrument panel top pad. Following a pas-
senger airbag deployment, the passenger airbag and
the instrument panel top pad must be replaced. If
inspection reveals that the passenger airbag mount-
ing points on the instrument panel structural duct
have been cracked or damaged, the instrument panel
structural duct assembly must also be replaced.
OPERATION
The multistage passenger airbag is deployed by
electrical signals generated by the Airbag Control
Module (ACM) through the passenger airbag squib 1
and squib 2 circuits to the two initiators in the air-
bag inflator. By using two initiators, the airbag can
be deployed at multiple levels of force. The force level
is controlled by the ACM to suit the monitored
impact conditions by providing one of four delay
intervals between the electrical signals provided to
the two initiators. The longer the delay between
these signals, the less forcefully the airbag will
deploy.
The hybrid-type inflator assembly includes a small
canister of highly compressed gas. When the ACM
sends the proper electrical signal to the airbag infla-
tor, the initiator generates enough heat to ignite
chemical pellets within the inflator. Once ignited,
these chemical pellets burn rapidly and produce the
pressure necessary to rupture a containment disk in
the pressurized gas canister. The inflator and gas
canister are sealed to the airbag cushion so that all
of the released inert gas is directed into the airbag
cushion, causing the cushion to inflate. As the cush-
ion inflates, the passenger airbag door will bend back
the instrument panel top pad at the predetermined
hinge line, then fold back over the top of the instru-
ment panel and out of the way. Following an airbag
deployment, the airbag cushion quickly deflates by
venting the inert gas through vent holes within the
fabric used to construct the sides of the airbag cush-
ion.

FRONT WASHER HOSES/
TUBES
DESCRIPTION
The front washer plumbing consists of a small
diameter rubber hose that is routed from the barbed
outlet nipple of the front washer pump/motor on the
washer reservoir along the filler neck into the engine
compartment. In the engine compartment, a molded
plastic in-line fitting with barbed nipples joins the
washer hose to another section of hose that is routed
near the left headlamp and dash wire harness to the
cowl plenum area. The engine compartment washer
hose passes from the engine compartment into the
cowl plenum area through a dedicated hole with a
rubber grommet near the left end of the cowl plenum
panel. A molded plastic elbow fitting with barbed nip-
ples joins the engine compartment hose to the cowl
grille cover hose. The cowl grille cover washer hose is
routed through routing clips on the underside of the
cowl grille cover to a molded plastic wye fitting with
barbed nipples and an integral check valve. The cowl
grille cover hose is connected to one nipple on the

FRONT WASHER PUMP/
MOTOR
DESCRIPTION
The front washer pump/motor unit is located on
the outboard side and near the front of the washer
reservoir, between the left front inner and outer
fender panels (Fig. 5). A small permanently lubri-
cated and sealed electric motor is coupled to the
rotor-type washer pump. A seal flange with a large
barbed inlet nipple on the pump housing passes
through a rubber grommet seal installed in one of
two dedicated mounting holes near the bottom of the
washer reservoir. The front washer pump/motor unit
is always mounted in the lower pump mounting hole
of the reservoir. A smaller barbed outlet nipple on the
pump housing connects the unit to the front washer
hose. The washer pump/motor unit is retained on the
reservoir by the interference fit between the barbedpump inlet nipple and the grommet seal, which is a
light press fit. An integral electrical connector recep-
tacle is located on the top of the motor housing. The
front washer pump/motor unit cannot be repaired. If
faulty or damaged, the entire washer pump/motor
unit must be replaced.
OPERATION
The front washer pump/motor unit is connected to
the vehicle electrical system through a single take
out and two-cavity connector of the left headlamp
and dash wire harness. The washer pump/motor is
grounded at all times through a take out of the left
headlamp and dash wire harness with a single eyelet
terminal connector that is secured under a ground
screw to the top of the left inner fender shield in the
engine compartment. The front washer pump/motor
receives battery current on a fused ignition switch
output (run-acc) circuit through the closed contacts of
the momentary front washer switch within the right
multi-function switch only when the switch control
stalk is pulled towards the steering wheel. Washer
fluid is gravity-fed from the washer reservoir to the
inlet side of the washer pump. When the pump motor
is energized, the rotor-type pump pressurizes the
washer fluid and forces it through the pump outlet
nipple, the front washer plumbing, and the front
washer nozzles onto the windshield glass.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.

FRONT WIPER ARM
DESCRIPTION
The front wiper arms are the rigid members
located between the wiper pivots that protrude from
the cowl plenum cover/grille panel near the base of
the windshield and the wiper blades on the wind-
shield glass. These wiper arms feature an over-center
hinge that allows easy access to the windshield glass
for cleaning. The wiper arm has a die cast metal
pivot end with a large mounting hole with internal
serrations at one end. A molded black plastic cap fits
over the wiper arm retaining nut to conceal the nut
and this mounting hole following wiper arm installa-
tion. The wide end of a tapered, stamped steel chan-
nel hinges on and is secured with a hinge pin to the
blade end of the wiper arm pivot end. One end of a
long, rigid, stamped steel strap, with a small hole
near its pivot end, is riveted and crimped within the
narrow end of the stamped steel channel. The tip of
the wiper blade end of this strap is bent back under
itself to form a small hook. Concealed within the
stamped steel channel, one end of a long spring is
engaged with a wire hook on the underside of the die
cast pivot end, while the other end of the spring is
hooked through the small hole in the steel strap. The
entire wiper arm has a satin black finish applied to
all of its visible surfaces.
A wiper arm cannot be adjusted or repaired. If
damaged or faulty, the entire wiper arm unit must be
replaced.
OPERATION
The front wiper arms are designed to mechanically
transmit the motion from the wiper pivots to the
wiper blades. The wiper arm must be properly
indexed to the wiper pivot in order to maintain the
proper wiper blade travel on the glass. The mounting
hole formation with internal serrations in the wiper
arm pivot end interlocks with the serrations on the
outer circumference of the wiper pivot driver, allow-
ing positive engagement and finite adjustment of this

CAL/REAR WIPERS/WASHERS - CLEANING). If
after cleaning the wiper blade and the glass, the
wiper blade fails to clear the glass without smearing,
streaking, chattering, hazing, or beading, replace the
wiper blade. Also, if a wiper blade is damaged or if
the squeegee rubber is damaged or deteriorated,
replace the wiper blade with a new unit. Do not
attempt to repair a wiper blade that is damaged.
WASHER SYSTEM
The washer system components should be
inspected periodically, not just when washer perfor-
mance problems are experienced. This inspection
should include the following points:
(1) Check for ice or other foreign material in the
washer reservoir. If contaminated, clean and flush
the washer system. (Refer to 8 - ELECTRICAL/
REAR WIPERS/WASHERS - CLEANING).
(2) Inspect the washer plumbing for pinched, leak-
ing, deteriorated, or incorrectly routed hoses and
damaged or disconnected hose fittings. Replace dam-
aged or deteriorated hoses and hose fittings. Leaking
washer hoses can sometimes be repaired by cutting
the hose at the leak and splicing it back togetherusing an in-line connector fitting. Similarly, sections
of deteriorated hose can be cut out and replaced by
splicing in new sections of hose using in-line connec-
tor fittings. Whenever routing a washer hose or a
wire harness containing a washer hose, it must be
routed away from hot, sharp, or moving parts. Also,
sharp bends that might pinch the washer hose must
be avoided.
REAR WASHER HOSES/TUBES
DESCRIPTION
The rear washer plumbing consists of small diam-
eter rubber hoses and molded plastic inline connector
fittings (Fig. 2). The washer reservoir hose is con-
nected to the barbed outlet nipple of the rear washer
pump/motor unit below the left front wheel house
extension and routed up the washer reservoir filler
neck to the engine compartment. Just rearward of
the washer reservoir filler neck in the engine com-
partment, an inline connector with barbed nipples
joins the reservoir hose to the engine compartment
hose. The engine compartment hose is routed along
the top of the left front fender wheel house to the
dash panel. The engine compartment hose passes
through a hole with a rubber grommet in the dash
panel into the passenger compartment. Below the
instrument panel in the passenger compartment near
the left cowl side inner panel, another inline connec-
tor joins the engine compartment hose to the A-pillar
hose. The A-pillar hose is routed up the left A-pillar
to the headliner. At the headliner, an inline connector
joins the A-pillar hose to the headliner hose. The
headliner hose is routed above the headliner and
