GENERAL INFORMATION
INTRODUCTION
The purpose of the dash gauges and indicator
lamps is to keep the driver informed about the oper-
ating condition of the vehicle. If an abnormal condi-
tion occurs, the driver is informed by indicator lamp.
The driver can seek service before damage occurs.
Indicator lamps use ON/OFF switch functions for
operation, while gauges use a sending unit or sensor.
The Instrument Panel can be removed as an
assembly after a few part are removed to allow
access to the retaining bolts. There is one self-align-
ing bulkhead connector on the left underside of the
instrument panel replacing most of the main harness
connectors. Once removed, the instrument panel can
be serviced for replacement. Most of the parts of the
instrument panel can be replaced individually with-
out removing the complete instrument panel assem-
bly.

DESCRIPTION AND OPERATION
SPEED CONTROL SYSTEM
OPERATION
The speed control system is electronically con-
trolled and vacuum operated. The electronic control
is integrated into the Powertrain Control Module
which is located in the engine compartment. The con-
trols are located on the steering wheel and consist of
five switches. The ON, OFF and SET buttons are
located on the left side of the airbag module. The
RESUME, ACCEL, COAST and CANCEL buttons
are located on the right side of the airbag module
(Fig. 1).
The system is designed to operate at speeds above
25 mph (40 km/h).
WARNING: THE USE OF SPEED CONTROL IS NOT
RECOMMENDED WHEN DRIVING CONDITIONS DO
NOT PERMIT MAINTAINING A CONSTANT SPEED,
SUCH AS IN HEAVY TRAFFIC OR ON ROADS THAT
ARE WINDING, ICY, SNOW COVERED, OR SLIP-
PERY.
The speed control can be disengaged manually by:
²Stepping on the brake pedal
²Depressing the OFF switch
²Depressing the CANCEL switch.
The speed control can be disengaged also by any of
the following conditions:
²An indication of Park or Neutral
²The VSS signal increases at a rate of 10 mph
per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
²Depressing the clutch pedal.
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear)²The VSS signal decreases at a rate of 10 mph
per second (indicates that the vehicle may have
decelerated at an extremely high rate)
²If the actual speed is not within 20 mph of the
set speed
The previous disengagement conditions are pro-
grammed for added safety.
