GENERAL INFORMATION

The vehicle speed control is electronically con-

trolled and vacuum operated. The electronic control
is integrated into the powertrain control module, lo-
cated next to battery. The controls are located on the
steering wheel and consist of the ON/OFF, RESUME/
ACCEL and SET/DECEL buttons (Fig. 1). For iden-
tification and location of the major components (Fig.
2 through 8).

The system is designed to operate at speeds above

35 mph (50 km/h).

WARNING: THE USE OF VEHICLE SPEED CON-
TROL 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 SLIPPERY.

TO ACTIVATE: The ON/OFF button to the de-

pressed latched position, ON, the vehicle speed con-
trol function is now ready for use.

TO DEACTIVATE: A soft tap of the brake pedal,

normal brake application or depressing the clutch
pedal while the system is engaged will disengage ve-
hicle speed control without erasing memory. A sud-
den increase in engine rpm may be experienced if the
clutch pedal is depressed while the vehicle speed con-
trol is engaged. Pushing the ON/OFF button to the
unlatched position or turning off the ignition erases
the memory.

TO SET SPEED: When the vehicle has reached

the desired speed push the SET/DECEL button to en-
gage system which will then automatically maintain
the desired speed.

TO DECELERATE: When vehicle speed control is

engaged, holding the SET/DECEL button depressed
allows the vehicle to coast to a lower speed setting.
