Cruise Control: Description and Operation
Lever Switch
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 38.6 kph (24 mph) but not more than 155 kph (96 mph), the target speed can be set by
selecting the SET function for 10 to 300 milliseconds. If SET is selected for more than 300 milliseconds, the cruise 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. If the accelerator is pressed by the driver until the actual speed is more than 35 kph (22 mph) over the target speed, or until the vehicle
exceeds 160 kph (99 mph), the cruise control will disengage.
Coast - If a target speed has been set and COAST is selected for at least 300 milliseconds, the throttle is allowed to 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 32.2 kph (20
mph) while coasting, the cruise control will be disengaged. If the switch is released between 32.2 kph (20 mph) and 38.6 kph (24 mph), the minimum
target speed of 38.6 kph (24 mph) will be used.
Resume - If the cruise control is ON and the system is disengaged by using the brake or the clutch, exceeding the maximum speed, failing to maintain
the minimum speed, or exceeding the target speed by more than 35 kph (22 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 10 to 300 milliseconds. If the
actual speed is below the target speed when RESUME is selected, the vehicle will be accelerated at 3.4 kph per second (2.1 mph/second) until the
vehicle is within 10 kph (6 mph) of the target speed, and then acceleration will be reduced in order to achieve a smooth transition from acceleration to
cruising. 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. In that case, the current speed will be maintained as the new target speed.
Accelerate - If cruise control is ON, and the ACCEL function is selected for more than 300 milliseconds, the vehicle will accelerate. The acceleration is
maintained at the rate of 3.4 kph per second (2.1 mph/second) as long as vehicle performance is sufficient; otherwise full throttle is applied. When the
switch is released, the current speed will be stored and used as the new target speed. The ACCEL function cannot be used for acceleration above 155
kph (96 mph). If 155 kph 96 mph) is attained, acceleration will stop and 155 kph (96 mph) will be set as the new target speed.
Tap-Up - If the cruise control has been set, and RESUME is selected again for more than 10 milliseconds but less than 300 milliseconds, the target
speed will be increased by kph (1.2 mph) each time the RESUME function is selected (or tapped). If the driver has used the accelerator to increase
speed more than 8 kph over the current target speed, a tap-up signal will be interpreted as a normal SET signal. The cruise control will not accept a
tap-up target speed above 155 kph (96 mph). If the actual speed has fallen 16.1 kph (10 mph) below the target speed, tap-up signals are not accepted.
Tap-Down - If the cruise control is already set and SET is selected for between 10 and 300 milliseconds, the target speed will be decreased by 2 kph
(1.2 mph) each time SET is selected (or tapped). Tap-down signals will not be accepted for a target speed below 38.6 kph (24 mph). If the vehicle
speed has increased to 8 kph (5 mph) over the target speed, the cruise control system will interpret a tap-down signal as a SET.
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 in order 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.
