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
programmable 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 system diagnostics, and communicates via the
Programmable 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 indication of relative distance to obstacles. When the
system is engaged and no obstacles are detected, the two outermost yellow LED's are lit at reduced brightness 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 system, use a scan tool and the appropriate body diagnostic information.
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
-

The cluster is responsible to set priority on all warning lamp announcement chimes.
CHIME ON CONDITIONS
SEAT BELT UNBUCKLED "BELTMINDER"
NOTE: If the vehicle is equipped with the Occupant Classification System (OCS), this will apply to the front passenger seat belt as well.
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/passenger seat belt is unbuckled.
When the Enhanced announcement is ENABLED;
