Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at vehicle speeds above 40 km/h (25 mph). Steep grades may cause variations in the selected vehicle speeds.

The following are the main components of the cruise control system:

• The powertrain control module (PCM)
• The On/Off switch
• The Resume/Accel switch
• The Set/Coast switch
• The torque converter clutch (TCC)/brake switch
• The stop lamp switch
• The throttle actuator control (TAC) module
• The vehicle speed sensor
