When you do begin to decelerate your car, the cruise control will need to be disengaged or deactivated. Your vehicle is equipped with redundant switches to ensure it is possible to turn off your cruise control even if one switch fails to operate. There is a clutch release switch on vehicles equipped with a manual transmission that cancels the cruise control set speed when the clutch pedal is depressed. There is also an on/off or cancel button on the steering wheel or column that will deactivate the cruise set speed. A vacuum brake bleed switch is equipped on older vehicles which will also cut out the cruise control. All vehicles will be equipped with a cruise control brake release switch. When the brake pedal is pressed, a switch on or behind the pedal is hit that opens a circuit. The cruise control servo or module detects a loss of continuity and cancels the cruise control set speed. If the brake release switch isn’t working and does not ‘open’, the cruise control will not cancel via the brake switch. If the switch will not ‘close’ the circuit, the cruise control will not set in the first place.
It is common for a burned out brake light bulb to cause the cruise control to not set, so if the cruise control is inoperative, have the brake lights checked first. The brake release switch does not require any maintenance and will last the vehicle's lifetime in many instances; however, it can fail just like any other electrical component. Have the cruise control checked and repaired by one of our expert technicians if stops working.
Cruise control is a convenience item and is not necessary for the safe operation of your vehicle. If the cruise control isn’t working, have it repaired at your convenience.
