Using the gas pedal allows you to accelerate and steer on the road, but this can be a chore when driving long distances on relatively flat roads with little or no traffic. This can lead to fatigue, leg cramps, and more. Speed ​​control (also known as cruise control) is a handy feature built into many modern vehicles that allows you to manually bypass obstacles in these circumstances using the gas pedal.

Your vehicle's speed control system allows you to set a speed and the computer then maintains it. You can also accelerate and slow down without hitting the gas or brake - you just need to use the cruise control selector to tell the computer what you want to do. You can even restore your previous speed if you had to disable cruise control due to traffic. It also improves fuel economy because the car's computer is much more efficient than the human driver.

The key to the system is the speed control unit. In newer vehicles, this is a computerized component that controls all aspects of your cruise control system. Like all other electronics, the speed control assembly is subject to wear. The only salvation is that it is only used when you turn on the cruise control system and set the speed. However, the more you use the system, the more it will wear out. Theoretically, this should be enough for the entire life of the car, but this is not always the case.

Old cars don't use computers. They use a vacuum system and a servo/cable assembly to control cruise functions.

If your car's speed control unit starts to fail, you'll notice a few telltale symptoms whether you have a newer computerized system or an older vacuum-powered model. This includes:

• Vehicle loses set speed for no reason (note that some vehicles are designed to exit cruise after decelerating to a certain speed)

• Cruise control doesn't work at all

• The vehicle will not return to the previously set speed (note that some vehicles do not regain their previous speed after decelerating to a certain point)
