Cruise control does not consume more fuel. If driving on a straight highway without frequent deceleration, activating cruise control allows the vehicle's fuel injection and throttle opening to be managed by the onboard computer. This results in more uniform fuel injection and speed, reducing unnecessary speed variations and thereby improving fuel efficiency. Cruise control, also known as speed control or autonomous driving system, enables drivers to avoid manually operating the accelerator pedal during long highway drives, reducing fatigue and unnecessary speed changes, which helps save fuel.

What does tripreset mean?

tripreset button means the trip mileage, which can record the kilometers driven within a certain period. If you want to reset the mileage, you can long press the trip button to clear it. Here are some related information about the car odometer: 1. Identification method: There are generally two ways to read the car odometer: pointer and digital scrolling. The pointer indicates the actual mileage at the time of driving, which is the speed per hundred kilometers. The digital scrolling shows the actual kilometers driven. The scrolling numbers can also be divided into two types: changeable and unchangeable. The changeable ones are four-digit, while the unchangeable ones are six-digit or more. 2. Content included: The trip mileage usually has four digits for short-term counting, which can be reset. The total mileage has six digits and cannot be reset. The accumulated mileage numbers of the electronic odometer are stored in non-volatile memory, so the data can be preserved even without power.

What is the purpose of an oil cooler?

An oil cooler ensures the vehicle's engine operates smoothly by reducing engine temperature, aiding in heat dissipation, filtering engine oil, and enabling normal vehicle operation. The primary function of an oil cooler is to dissipate heat from the engine oil. More details are as follows: 1. Heat generation during engine operation: Engine oil forms a protective film on the surfaces of engine components, preventing direct contact and friction between them. If components were to directly rub against each other, it would instantly generate excessive heat. 2. The role of the oil cooler: During engine operation, the oil temperature rises, but it must remain within a normal operating range. Excessively high oil temperatures are unacceptable as they can impair engine lubrication. Therefore, some vehicles are equipped with an oil cooler to regulate oil temperature.
