SET/COAST Switch (Button)

The cruise control SET/COAST switch controls three functions:

• Set Function
  
  When the SET/COAST switch is depressed and then released (car speed must exceed the low speed limit point, and the instrument panel switch must be in the ON position) the cruise speed will be set at the particular speed the car was at when the button was released. See Figure . Car cruise speed will be plus or minus one MPH of the actual speed when engaged. The system will cruise until either the ON/OFF switch is moved to OFF, the ignition switch is turned off, and/or the SET/COAST button is pushed in fully and held. Pushing the brake pedal releases the cruise but not the resume capability.
• Coast (Trim) Function
  
  When the SET/COAST button is fully depressed, the driver can raise or lower his control speed. To increase control speed, the driver would accelerate to a new speed, fully depress the switch Electronic Control Module (ECM) releases previously set speed and release the button. Upon releasing the button a new speed is set. An increased control speed can also be more easily set by the Resume/Accel (R/A) switch as described later. To decrease cruise speed, the SET/COAST switch is held in (depressed position) disengaging the cruise system, and allowing the throttle to return to the idle position. When the car has slowed to the desired lower cruise speed, releasing the switch will re-engage the system.
• "Tap-Down" Function
  
  For this function to operate the cruise must be engaged and operating. "Tapping-down" is done by quickly pressing the SET/COAST button to the depressed position and quickly releasing it, or "tap" the button. Do not hold the button in the depressed position or the system will revert to the COAST mode. "Tap-down" is a function in which cruise speed can be decreased by one MPH increments (one tap equals one MPH decrease). The system can "tap-down" below the engage speed lockout (25 mph) to 16 mph, below this speed cruise will not operate. The accelerator may be depressed at any time to override the cruise system. Release of the accelerator will return the car to the previous set cruise speed.
