How to operate the cruise control of the car

How to operate the cruise control is one of the important techniques that the driver resorts to on long trips, as he can not press the car engine and rely on the cruise control to move the car at the speed he wants, and how to operate the cruise control is not a difficult way, which is similar in most models the cars.

Who is the inventor of cruise control?

The credit for the emergence of cruise control is attributed to the scientist “Ralph Teetor”, who received a bachelor’s degree from the College of Science in Mechanical Engineering from the University of Pennsylvania.

The cruise control was first patented in 1945. The cruise control was first applied to the Chrysler Imperial, New Yorker and Windsor cars in 1958.

Cruise control information

The motorist who intends to use the cruise control must be fully aware of how to operate the cruise control, and know the consequences of using it.

And the places where the cruise control is supposed to be used, and what to do if an error or malfunction occurs in the stabilizer, and this is summarized in the following points:

  • It is preferable to hold the speed between 88.5 and 112.5 km/h so that the driver can deal with any sudden event.
  • Avoid using cruise control in bad weather and crowded places, as highways and semi-free roads are the best way to operate cruise control.
  • Know all the cruise control buttons and when to use each one before you start using it.
  • Make sure to stay alert and keep an eye on the road in case you need to change gear or disable cruise control.

How to operate cruise control

The function of the cruise control is not limited to a fixed speed only, but it is possible to raise and lower the speed through it, or to save a certain speed and use it when needed. The cruise control consists of five buttons, namely:

  • “On” button.
  • The “Off” button.
  • Speed ​​adjustment button “Set/ Accel”
  • The “Coast” button.
  • Resume button.

You can follow the following steps to learn how to turn on cruise control:

  • Press the “On” button to turn on the system.
  • Choose the speed you want to go, followed by pressing the Set button to set the speed.
  • To increase the speed, press the Set button again, or the (+) button, if present, and to decrease the speed, press the (-) or the coast button.
  • Release the brake pedal and let the vehicle go at the chosen speed.
  • To stop the system, press the off button, or apply the brakes.
  • In the event that you disable the system by depressing the brake pedal and want to return to the set speed, you can press the resume button.
  • If you disable the system by pressing the off button, you cannot return to the previously installed speed, but rather it requires you to re-enter the speed at which you want to install again.

The most important malfunctions that occur in the cruise control

Here is a list of the most common malfunctions that occur to the cruise control and its attached parts, as well as the most important signs that indicate a malfunction in the cruise control, which are as follows:

Cruise control malfunction

The cruise control may stop working due to several factors

Cruise control fuse damaged

  • Like any electrical circuit, the fuse is placed in series with the components of the circuit, so that the circuit does not burn out when any error occurs. This affects the fuse and keeps the circuit intact, and this is fixed by changing the fuse.

Check engine mark appears

  • If you notice an engine warning light appears, it means something is wrong with the engine, and the engine control unit will turn off the cruise control to avoid any accidents, until the engine is repaired.

Steering wheel damaged

  • When a malfunction occurs in the steering wheel, many systems inside the car stop, such as the air horn and the control keys responsible for cruise control.

Brake light switch damaged

  • Since the brake lamp switch is connected to the cruise control, as soon as the brake brake is pressed, the brake lamp lights up, signaling the cruise control to stop.
  • When the brake lights fail, the cruise control does not feel this and thinks that it is still working, and therefore the cruise control does not stop working.

Speed sensor damage

  • The car has a speed sensor, which in turn transmits the vehicle’s speed to the engine control unit and the cruise control unit.

Therefore, if a malfunction or damage to the speed sensor occurs, the control unit will not be able to know the vehicle’s speed, and therefore the cruise control will be turned off automatically.
