ENGINE COOLANT
THERMOSTAT
DESCRIPTION
The engine cooling thermostats are a wax pellet
driven, reverse poppet choke type. The thermostat is
mounted in a housing on the coolant outlet of the
engine (Fig. 8) or (Fig. 10).
OPERATION
The engine cooling thermostat is a wax pellet
driven, reverse poppet choke type. The thermostat is
designed to provide the fastest warm up possible by
preventing leakage through it and to guarantee a
minimum engine operating temperature of 88 to
93ÉC (192 to 199ÉF). The thermostat also will auto-
matically reach wide open so it will not restrict flow
to the radiator as temperature of the coolant rises in
hot weather to around 104ÉC (220ÉF). Above this
temperature the coolant temperature is controlled by
the radiator, fan, and ambient temperature, not the
thermostat.
The thermostat is operated by a wax filled con-
tainer (pellet) which is sealed. When heated coolant
reaches a predetermined temperature, the wax
expands enough to overcome the closing spring and
water pump pressure, which forces the valve to open.
DIAGNOSIS AND TESTING - ENGINE COOLANT
THERMOSTAT
The thermostat is operated by a wax filled cham-
ber (pellet) which is sealed. When heated coolant
reaches a predetermined temperature the wax pellet
expands enough to overcome the closing spring and
water pump pressure, which forces the valve to open.
Coolant leakage into the pellet will cause a thermo-
stat to fail open. Do not attempt to free up a thermo-
stat with a screwdriver.
Thermostat diagnostics is included in powertrain
control module's (PCM) programing for on-board
diagnosis. The malfunction indicator light (MIL) will
illuminate and a diagnostic trouble code (DTC) will
be set when an ªopen too soonº condition occurs. Do
not change a thermostat for lack of heater perfor-
mance or temperature gauge position, unless a DTC
is present. For other probable causes, (Refer to 7 -
COOLING/ENGINE - DIAGNOSIS AND TESTING).
Thermostat failing shut is the normal long term
mode of failure, and normally, only on high mileage
vehicles. The temperature gauge will indicate this

²Key-In Ignition
²Engine Temperature Critical
²Turn Signals ON
²Dome Lamp ON
²Low Oil Pressure
²High Speed Warning

HIGH SPEED WARNING - EXPORT
The chime will sound, acting as a warning to the
driver that the vehicle speed has exceeded 120   3
Kp/h (75   2 mph).
Refer to the proper body diagnostic information
diagnosis and testing with a scan tool.
PARK ASSIST SYSTEM
The Park Assist System is an electronic parking
aid that alerts the driver to obstacles which are
located immediately behind the vehicle. Objects are
sensed using ultrasonic sound waves. When an object
is detected, the system will give the driver visual and
audible warnings. The system is customer program-
mable through the Electronic Vehicle Information
Center (EVIC) but will be enabled from the factory
as a default.
The major components of the park assist system
are:²Park Assist Module- supplies voltage to the
object detection sensors and park assist display. It
triggers the sensors, analyzes the echo delay times
and calculates obstacle distances. It sends display
information to the park assist display, performs sys-
tem diagnostics, and communicates via the Program-
mable Communication Interface (PCI) date bus
network.
²Park Assist Sensors- there are four sensors
located in the rear bumper that generate ultrasonic
pulses when triggered by the park assist module. The
sensors signal the park assist module when reflected
ultrasonic pulses are received.
²Park Assist Display- there are sixteen Light
Emitting Diode (LED) indicators which provide indi-
cation of relative distance to obstacles. When the sys-
tem is engaged and no obstacles are detected, the
two outermost yellow LED's are lit at reduced bright-
ness to show the system is working. As the distance
to a detected obstacle decreases, more yellow LED's
towards the center of the display illuminate.
For diagnosis and testing of the park assist sys-
tem, use a scan tool and the appropriate body diag-
nostic information.
OPERATION
Refer to the proper Body Diagnostic Procedures
manual for complete chime/buzzer operation and con-
ditions for operation.
HIGH SPEED WARNING - EXPORT
When the vehicle speed sensor sees 120   3 Km/h
(75   2 mph), it sends a PCI data bus message to the
Body Control Module (BCM). The BCM then turns on
the chime to let the driver know that the vehicle has
reached a speed greater than 120   3 Km/h (75   2
mph). This audible message will continue until the
vehicle is slowed below the predetermined speed.
RSCHIME/BUZZER8B-1

PARK ASSIST SYSTEM
The Park Assist System display activates an audi-
ble tone that changes from intermittent to continu-
ous as the final two Light Emitting Diodes (LED's)
are illuminated on one side or both sides of the dis-
play.
The system detection length from the rear of the
vehicle is 0.3 meters to 1.5 meters. This area extends
around the rear side of the vehicle. The system detec-
tion height from the ground is 0.2 meters to about
1.5 meters. The radio mutes when the system acti-
vates its audible tone.
When the driver selects Reverse the system scans
for objects behind the vehicle using four sensors
located in the rear bumper. A warning display above
the rear window provides both visible and audible
warnings indicating the range of the object.
The system is active only when the transmission
gear selector is in reverse for vehicle speeds less than
16 Km/h (10 mph). If the vehicle's Parking/Emer-
gency Brake is applied, the system is deactivated.
The display contains two sets of yellow and red
Light Emitting Diode's (LED's) that the driver can
see as they look over their shoulder while backing
up. Each side of the vehicle has its own warning
LED's. The system provides a visual warning by illu-
minating one or more yellow LED's as the vehicle
gets closer to the object. As the vehicle continues to
approach the object, one red LED is illuminated and
the system emits a series of short beeps. The tone
will remain constant and both red LED's are illumi-
nated once the vehicle is within 12 inches (30.5 cm)
of the object.
The system can be turned ON or OFF through the
Electronic Vehicle Information Center (EVIC) when
the vehicle is in PARK. If the park assist system is
turned OFF, a single chime will sound and the EVIC
will display the following message ªREAR PARK
ASSIST OFFº, when the vehicle is in reverse.
²Ensure that the rear bumper is free of dirt and
debris to keep the system operating properly.
²Jackhammers, large trucks, and other vibrations
could affect the performance of the system.
²Ensure that the parking brake is not applied.
If ªService Park Assist Systemº appears in the
EVIC after making sure the rear bumper is clean,
proceed to diagnose the system using a scan tool and
the appropriate diagnostic information.
WARNING
On vehicles equipped with airbags, disable
the airbag system before attempting any steer-
ing wheel, steering column, or instrument
panel component diagnosis or service. Discon-
nect and isolate the battery negative (ground)
cable, then wait two minutes for the airbag sys-
tem capacitor to discharge before performing
further diagnosis or service. This is the only
sure way to disable the airbag system. Failure
to take the proper precautions could result in
accidental airbag deployment, personal injury,
or death.
DIAGNOSIS AND TESTING - CHIME SYSTEM
Refer to the proper Body Diagnostic Procedures
manual for complete Diagnosis and Testing of the
Chime System.

PARK ASSIST DISPLAY
DESCRIPTION
The Park Assist Display is located in the rear of
vehicle, over the rear window in the headliner (Fig.
1). It is a molded plastic unit housing Light Emitting
Diodes (LED's) and a chime module. Located in the
rear of the vehicle for easy visual reference when the
driver is backing up.
The display is used to alert the driver of any obsta-
cles detected in the rear of the vehicle. The chime or
audible signal also comes from the display unit.
OPERATION
When the ignition is put in the RUN position, all
the Light Emitting Diodes (LED's) will illuminate for
approximately one second. This will be interrupted if
the system senses an obstacle.
The ready status will be sensed by the outermost
two yellow LED's being illuminated at 50% intensity.
As the obstacle is sensed, the yellow LED's will start
illuminating inward until the object in approximately
one foot away and then the inner red LED will light.
The display is sensitive to which side of the rear of
the vehicle that the object is detected. If on the left
rear, the left segments will light and the same for the
right side of the vehicle.
