Typically, the cruise control buttons can be found on the right-hand side of the steering wheel. Depending on the car, the location of the controls can vary, but the functionality of the cruise control will usually be similar across the board. Here are the basic buttons you can use to operate cruise control.
ON/OFF: To set the cruise control, press the ON/OFF button. You will see the cruise light illuminate on the dashboard which means the system is activated. To turn the system off, press this button again.
Res +: Press this button if you want to increase the cruising speed. Each time you hit the button, the vehicle will accelerate by 1 mph. You can also use this button to resume your previously set speed.
Set -: This button will decrease the set speed. Each time you press the button, the cruising speed will decrease by 1 mph. Once you reached the desired speed, hit the “Set” button and the “Cruise Set” icon will appear on the dashboard. Then you can take your foot off the gas pedal and the car will maintain the speed for you.
Cancel: When it's time to cancel the cruise control mode, like when you exit the highway or if there is heavy traffic ahead, press this button to disengage the cruise control system. Or you can simply depress the brake pedal to cancel the system.
