Cruise control is an electronic function that automatically maintains a constant speed when driving on long stretches of highway. The driver may accelerate briefly if necessary by pressing the accelerator pedal, but once the pedal is released, the vehicle returns to the cruise control speed set previously. 
Usable within a speed range from 30 to 200 km/h, this function is recommended for long, straight stretches of road 
and on dry tarmac, with minimal variations in traffic conditions. Not recommended for use on urban roads.
