If there is the word "AUTO" on the control lever of the light, it means that your car has the function of automatic headlights. Automatic headlights are sensors that lean against the inside of the front windshield. They can sense the change of ambient light, and if the light darkens, they will automatically turn on the headlights.
Automatic headlights can be turned on automatically when entering tunnels or viaducts, which improves driving safety. You can also avoid turning on the headlights in time at night. In addition, even at night, the automatic headlights will automatically turn off after the key is pulled out, which can completely avoid the battery exhaustion caused by the unlit headlights.
2, one-button defogging
Whether it is an automatic air conditioner or a manual air conditioner, there is a one-button defogging function for the front windshield. I believe that the fog on the windshield has troubled many car owners before it rains, especially when it is cold, so it is not convenient to open the window. If it is foggy, you can press the defog button, and your vision will be restored in less than 3 seconds. Of course, this function is a stopgap measure. If it fogs again, you have to repeat the above steps.
3, rearview mirror heating
Very useful function in rainy and snowy days. Now many cars have the rearview mirror heating function, but the rearview mirror heating and the rear windshield heating are turned on at the same time, and there is no separate switch button. Heating the rearview mirror can avoid water mist on the rearview mirrors on both sides, make the surface view of the rearview mirror clear and greatly improve the driving safety in rainy days.
4. Head-up display system
The head-up display system uses the principle of optical refraction to transmit some important driving data of the vehicle to the front windshield of the vehicle. Of course, some models will have separate display screens, which generally include speed and navigation data, so that drivers do not need to look down at electronic instruments, which is more conducive to driving safety.
5. Intelligent driving information system
This system can remember the driver's driving habits to the greatest extent, such as the action of accelerator pedal or braking. It is a patent of Volvo, which means that when the driver drives to a time period when he frequently uses brakes and acceleration, it will delay the input of external information, such as car phone, so that the driver can concentrate on the driving situation on the road.
