Cruise Control: Description and Operation

2012 Ford Flex AWD V6-3.5L TurboSECTION Description and Operation



Cruise Control

The cruise control system consists of the following components:

- Cruise control switches

- Cruise control deactivator switch (integral to the stoplamp switch)

- Cruise control indicator

- PCM

- Electronically-controlled throttle body

- Clockspring

The cruise control system is controlled by the PCM. The cruise control system is designed to maintain a selected vehicle speed between 37 km/h (23 mph) and the maximum limited vehicle speed. The cruise control system is controlled by the steering wheel mounted switches (ON, OFF, SET+, SET-, and RESUME), and the brake pedal. The steering wheel mounted switches are hardwired to the PCM.

When a MyKey(TM) is used and the MyKey(TM) max speed limiter is turned on, the vehicle speed cannot be set to exceed 130 km/h (80 mph).
