Cruise control is a speed control system that
maintains a desired vehicle speed under normal dri-
ving conditions. However, steep grades up or down
may cause variations in the selected speeds. The !
electronic cruise control system has the capability to
cruise, coast, resume speed, accelerate, “tap-up” and
“tap-down”.
The main parts of the cruise control system are the
functional control switches, speed control assembly, actuator, intermediate link, auto-cruise control mod-
ule assembly, speed sensor, and the release
switches.
Depending upon the year and/or model of your
vehicle, the cruise control system is either vacuum or
electronically controlled. The cruise control module
assembly contains a low speed limit which will pre-
vent system engagement below 25 mph (40 km/h).
The module is controlled by the functional switches located on a lever on the steering column or steering
wheel and on the instrument panel.
The release switches are mounted on the
brake/clutch/accelerator pedal bracket. When the
brake or clutch pedal is depressed, the cruise control
system is electrically disengaged and the throttle is
returned to the idle position.

others, use a plastic trim tool to pry the lower pad of
the radio panel loose.
3. Remove the radio/tape/CD player mounting
bracket retaining screws, 4. Slide the radio chassis out of the instrument
*panel and disconnect the radio wiring harness and
*Depending on the speaker installation, it
may save time at installation to identify and
tag all wires before they are disconnected.
5. Remove the mounting brackets from the radio.
To install:
6. The installation is the reverse of the removal
procedure. Make all electrical and antenna connec-
tions before fastening the radio assembly in place.
7. Test all functions of the entertainment system
prior to final installation. If all are satisfactory, install
the unit and center panel.
8. Connect the negative battery cable and recheck
the entire system for proper operation. CD Changer
1. Disconnect the negative battery cable.
2. Open the trunk lid.
