Cruise Control Switch: Description and Operation

Cruise Control Switch Description

After the main switch is turned on and the neutral position of the lever switch is detected by the cruise control actuator, the following operations can be performed by using the cruise control lever switch:

Set
If the cruise control is on and the minimum speed is 29 km/h (18 mph) within +/- 2 mph (+/-3.2 kph), the target speed can be set by selecting the SET button for at least 35 milliseconds. If SET is selected for more than 1 second, the cruise control will be activated in the COAST function. If the accelerator is pressed by the driver after the cruise control has been set, the previous target speed will be maintained when the accelerator is released.

Coast
If a target speed has been set and COAST is selected for at least 1 second, the throttle will return to idle, and the vehicle will coast. When the COAST switch is released, the current speed will be maintained as the new target speed. If the vehicle speed drops below 29 km/h (18 mph) within +/- 2 mph (+/- 3.2 kph) while coasting, the cruise control will be disengaged.

Resume
If the cruise control is on, and the system was dis-engaged by using the brake or clutch, exceeding the maximum speed, failing to maintain the minimum speed, or exceeding the target speed by more than 32.2 km/h (20 mph), the last memorized speed can be reset by selecting RESUME if the time since disengagement is not greater than 5 seconds. The RESUME function is selected by switching to RESUME for at least 35 milli-seconds. If the actual speed is above the target speed when RESUME is selected, the throttle will be allowed to return to idle until the target speed is achieved. RESUME can be canceled by selecting SET, and then the current speed will be maintained as the new target speed.

Accelerate
If cruise control is on, and the ACCEL switch is selected for more than 1 second, the vehicle will accelerate. When the switch is released, the current speed will be stored and used as the new target speed.

Tap-Up
If the cruise control has been set, and RESUME is selected again for 35 milliseconds to 1 second, the target speed will increase by 1.6 km/h (1 mph) for each time that the RESUME button was selected (or tapped).

Tap-Down
If the cruise control is already set and SET is selected for between 35 milliseconds and 1 second, the target speed will decrease by 1.6 km/h (1 mph) for each time that SET was selected (or tapped).

If the cruise control is turned off with the main switch, all cruise control functions are stopped, the actuator cable is driven toward idle, and the electromagnetic clutch for the cable actuator is opened. The cable actuator clutch is not opened immediately to accomplish a smooth transition in vehicle speed. If the cruise control is off for more than 5 seconds, the memorized target speed is erased.
