cation Interface (PCI) data bus for requests from var-
ious modules to display messages and under certain
conditions sound a chime or series or chimes.

The chime system provides the Driver with warn-

ing chimes for:

• Seat Belt

• Exterior Lights On

• Key-In Ignition

• Key-In Accessory

• Engine Temperature Critical

• Low Washer Fluid

• Turn Signals On

• Low Oil Pressure

• Any Warning Lamp Announcement
The output sound intensity of the chime is approx-

imately 62 to 78 decibels.

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:

• Park 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.

• Park 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.

• Park 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

CHIME PRIORITY

The following list indicates the priority of the

chime when more than one chime is active at the
same time:

• Seat Belt Warning

• Door Ajar

• Turn Signal On

• Chime Request

• Power Liftgate
The cluster is responsible to set priority on all

warning lamp announcement chimes.

CHIME ON CONDITIONS

DRIVER’S SEAT BELT UNBUCKLED

There are two different Fasten Seat Belt Reminder

announcements incorporated into the cluster’s logic,
a Non-enhanced announcement and an Enhanced
announcement.

When the Enhanced announcement is DISABLED:
• The cluster will chime five times (not greater

than six seconds) and illuminate the Seat Belt Lamp
after turning the ignition to the run/start position if
the driver seat belt is unbuckled.

When the Enhanced announcement is ENABLED;
• The cluster will chime continuously at a slow

rate for a period of 6 seconds and illuminate the Seat
Belt Lamp after turning the ignition to the run/start
position if the driver seat belt is unbuckled. After 6
seconds the chime will stop, but the Seat Belt Lamp
will stay illuminated. If the ignition is in the run
position for a period greater than 60 seconds, and the
driver seat belt is unbuckled, and the vehicle’s speed
is greater than 5 mph (8 km/h) in a forward gear, the
Enhanced Fasten Seat Belt Reminder will activate.
This will cause the Seat Belt Lamp to blink and a
slow continuous chime to sound for 5 seconds. After 5
seconds, the chime will stop, but the lamp will
remain illuminated for an additional 3 seconds. The
Enhanced Seat Belt Reminder cycles for a total of 12
times (96 seconds). After the 12th time, the Seat Belt
Lamp will remain on without any chime. Buckling
the driver seat belt at anytime will cancel the Fasten
Seat Belt Reminder announcement.

EXTERIOR LIGHTS ON

Chime sounds if the ignition is in the lock position,

the drivers door is ajar, and the headlight switch is
in any position other than auto or off. The chime will
continue to sound until anyone of the above condi-
tions change or the battery protection time of 3 min-
utes expires.

KEY-IN IGNITION

Chime sounds if the key is in the ignition, the igni-

tion is in the lock position, and the drivers door is
ajar. The chime will continue to sound until anyone
of the above conditions change or the battery protec-
tion time of 15 minutes expires.

TURN SIGNAL ON

If the BCM detects a turn signal input continu-

ously for 1.0 mile (0.6 km) and the vehicle speed is
greater than 15 mph (24 km/h), the cluster will
chime continuously and display an EVIC warning
message, until the turn signal is cancelled.

LOW OIL PRESSURE

Chime sounds when the engine is operating and

the oil pressure drops below 4 psi/27.5 kPa.

ENGINE TEMPERATURE CRITICAL

Chime sounds when the engine is operating and

the coolant temperature exceeds 252°F (122°C). The
chime is continuous at 257°F (125°C) and will chime
for 4 minutes and stop if the temperature drops
below 243°F (117°C).

LOW WASHER FLUID

Chime sounds when the washer fluid drops below a

specific level.

WARNING LAMP ANNOUNCEMENT

Chime sounds to alert the driver to scan the EVIC

(in the cluster) to see which EVIC warning message
displayed. The door/liftgate ajar warning message
will display (without a chime) if the vehicle is run-
ning and a door or the liftgate is open. A chime will
sound if the door or liftgate is still open when vehicle
speed is greater than 1 mph (1.6 km/h).

WARNING LAMP ANNOUNCEMENT

LOW FUEL LAMP

The cluster will sound a single chime, illuminate

an amber lamp, and display an EVIC warning mes-
sage after illuminating the indicator.

VOLT LAMP

The cluster will sound a single chime after illumi-

nating the indicator.

OIL PRESSURE LAMP

The cluster will sound a single chime after illumi-

nating the indicator above 450 rpm vehicle operation.

FASTEN SEAT BELT LAMP

There are two different Fasten Seat Belt Reminder

announcements incorporated into the cluster’s logic,
a Non-enhanced announcement and an Enhanced
announcement.

When the Enhanced announcement is DISABLED:
• The cluster will chime five times (not greater

than six seconds) and illuminate the Seat Belt Lamp
after turning the ignition to the run/start position if
the driver seat belt is unbuckled.

When the Enhanced announcement is ENABLED:
• The cluster will chime continuously at a slow
