Cruise Control: Description and Operation

The speed control system consists of a speed control module, speed control switches, clutch pedal position switch (MTX models), brake switch, actuator, actuator cable and a vacuum dump valve.
To operate the speed control system, vehicle speed must be greater than 30 mph. At this time, the system is activated and is ready to accept a set speed signal by pressing the ON and SET ACCEL switches on the steering wheel. This will set speed at its current speed until a new speed is set by the operator, the brake pedal is depressed, the clutch pedal is depressed or the OFF switch is depressed.


Increasing Set Speed

Vehicle set speed can be increased in three ways: manually using the accelerator, pressing the SET ACCEL switch, tapping the SET ACCEL switch (Tap-Up). To manually increase set speed, depress the accelerator until the higher speed is reached and stabilized, then depress and release the SET ACCEL switch. Set speed can also be increased by depressing the SET ACCEL switch and holding it in that position, vehicle speed will then automatically increase, when desired speed has been obtained, release the switch. To increase vehicle speed using the Tap-Up method, tap the SET ACCEL switch once for each 1 mph until vehicle reaches desired speed.

Resume

When the speed control system is deactivated by depressing the brake pedal, the set speed prior to system deactivation may be reset by momentarily depressing the RESUME button. The RESUME function of the system will not function if the system is deactivated using the OFF switch, or if vehicle speed has been reduced below the minimum speed of 30 mph.
