Circuit Description

With the ignition switch in ON, the cruise control unit is powered. This system uses mechanical, electrical, and vacuum operated devices to maintain vehicle speed at a setting selected and controlled by the driver.

System Operation
The cruise control system will set and automatically maintain any speed above 25 mph (40 kph). To set, press the cruise control main switch so that the "CRUISE MAIN" indicator is ON. After reaching the desired speed, press the set switch. The cruise control unit will receive the set signal and activate the cruise control actuator.

Pushing the cruise control main switch cancels the cruise control system. This removes power to the cruise control unit and erases the set speed from memory. The cruise control system also disengages when cruising speed is lower than the preset speed by 12.5 mph (20 kph) or more. If the system is disengaged temporarily by the brake switch, clutch switch, or the automatic transmission mode switch, and vehicle speed is still above 25 mph (40 kph), the set memory is retained. Just turn and release the resume/accel switch, and the vehicle will automatically return to the previously set speed.

For gradual acceleration without depressing the accelerator pedal, turn the resume/accel switch and hold it there until the desired speed is reached. This will send an acceleration signal input to the cruise control unit. When the switch is released, the system will be reprogrammed for the new speed. Quickly turning and releasing the resume/accel switch allows you to tap up the preset cruising speed. Each turn-and-release increases the preset speed by 1 mph (1.6 kph). The preset speed can be increased by up to 10 mph (16 kph) this way.

To slow the vehicle down, depress and hold the set/coast switch. This will send a deceleration signal input to the cruise control unit, causing the vehicle to coast. When the desired speed is reached, release the set/coast switch. This will reprogram the system for the new speed. Quickly depressing and releasing the set/coast switch allows you to tap down the preset cruising speed. Each depress-and-release decreases the preset speed by 1 mph (1.6 kph). The preset speed can be decreased to a minimum of 25 mph (40 kph) this way.
