Set/Coast Button Switch

Cruise Control Actuator Lever (Typical):

The cruise control "SET/COAST" button switch (3) (located in the end of the turn signal and headlamp dimmer switch and cruise control actuator and windshield wiper and windshield washer lever ) has two positions - "NORMAL" and "DEPRESSED.
^ The Set Position - With the "SET/COAST" button switch depressed and then released (vehicle speed must exceed the low speed limit point, and the "OFF-ON-R/A" switch (2) must be in the "ON" position), the cruise speed will be set at the speed the vehicle was going when the "SET/COAST" button switch (3) was released. Vehicle cruise speed will be within 1.6 km/h (1 mph) of the actual speed at engaged speed. The system will cruise until either the "OFF-ON-R/A" switch (2) is moved to "OFF," the ignition switch is turned "OFF," and/or the "SET/COAST" button switch (3) is pushed in fully and held. Pushing the brake pedal releases the "SET/COAST" button switch (3) but not the resume capability.
^ The Coast Position - With the "SET/COAST" button switch (3) fully depressed, the driver can lower vehicle speed. To decrease cruise speed, the "SET/COAST" button switch (3) is held in, disengaging the cruise system, which allows the throttle to return to the idle position. When the vehicle has slowed to the desired cruise speed, releasing the "SET/COAST" button switch (3) will re-engage the system at the new selected speed.
^ The "Tap Down" Position - To lower "tap down" the cruise must be engaged and operating. "Tapping-down" is done by quickly pressing and releasing the "SET/COAST" button switch (3), or "tapping" the "SET/COAST" button switch (3). Do not hold the "SET/COAST" button switch (3) in the depressed position or the system will go into the coast mode. "Tap-down" is a function in which cruise speed can be decreased by 1.6 km/h (1 mph) increments (one tap 1.6 km/h (1 mph) decrease). The accelerator pedal may be depressed at any time to override the cruise system. Release of the accelerator pedal will return the vehicle to the previously set cruise speed.

CAUTION: To keep the vehicle under control, and to prevent possible personal injury and vehicle damage, the cruise control should not be use on slippery or winding roads or In traffic of heavy or varying volume. When traveling down a steeply graded hill, the cruise control should be disengaged by depressing the brake pedal lightly. The automatic transmission can then be shifted into a lower gear range to help control vehicle speed.
