Super practical functions hidden in cars
The heating of the rear-view mirror is generally applicable in rainy and snowy days. When the rear-view mirror is heated, the heater behind the mirror quickly heats the mirror, and the rain or fog on the mirror can be slowly removed. This saves the driver the trouble of frequently manually wiping the mirror, thus reducing the risk of driving.
When turning on the rear-view mirror heating switch, avoid mixing it with the front windshield. Although they are all three curved upward arrows, the figures are different. Although the vehicles are different and the positions of the keys are different, the heating switch pattern is the same.
In rainy and snowy weather, when the heating switch of the rear-view mirror is pressed, the indicator light on the button will be on, and the electric heater will be heated to a fixed temperature within a few minutes, generally between 35-60 degrees Celsius. At the same time, the water droplets on the rear-view mirror will become smaller and smaller due to heating and evaporation, and the fog will gradually disappear, so as to heat the lens and remove fog and frost.
Automatic headlamp
If there is "auto" on the left light control lever, it means that your car is equipped with automatic headlamp function. The automatic headlamp is a sensor inside the front windshield, which can sense the change of ambient light; If the light is dim, the headlights can be automatically turned on to improve driving safety. Even if you forget to turn off the automatic headlamp when parking at night, pulling out the car key will automatically turn off the function, which can completely avoid the battery loss caused by the headlamp not being turned off.
Interior rearview mirror anti glare
The major safety hazard of driving at night is the problem of line of sight, not only because the dark light is not good, but also because the headlights of all vehicles have an impact on driving safety; In case of irregular drivers driving behind with high beam for a long time, the interior rearview mirror directly reflects the strong light into the eyes, and the dazzling strong light directly affects the safety of driving. In order to reduce the occurrence of danger, the automatic anti glare function of the rearview mirror came into being.
One is manual, which suppresses glare through optical principle. This kind of rear-view mirror uses a double reflectivity mirror. When the driver thinks that the reflected light is too strong and feels dazzling, he can manually stir the rear-view mirror angle adjustment lever to make the rear-view mirror angle offset. At this time, the reflectivity of the mirror is small, which can naturally weaken the light intensity. The models with higher configuration are equipped with automatic anti glare rear-view mirrors, which are equipped with photodiodes behind the mirror. When the diodes sense strong light, the control circuit will apply voltage to the ionosphere of the mirror, and the lens will darken under the effect of voltage to achieve the purpose of anti glare.
Vehicle speed automatic control volume
Friends who often like to listen to music while driving must have had similar experiences. When we are listening to music while driving at a relatively low speed, when the front suddenly opens up and can accelerate, the tire noise and wind resistance noise in the car will increase with the increase of the speed. At this time, when we listen to music, we feel the music sound is small, and then we need to adjust the volume by hand. In fact, some cars have the function of "automatic speed control and volume matching" in the original multimedia system. The volume of the car will be adjusted according to the speed of the car. Generally speaking, the automatic change range is adjusted to be large, so that the sound we hear will be relatively "fixed". When the speed is low, the volume will become smaller, and when the speed is increased, the volume will also become larger.
The oil gauge lamp can show which side the oil tank cap is
Drivers who have just bought a new car, borrowed a car or rented a car must have such embarrassment: after driving to the gas station, they find that they do not know whether the fuel tank port is on the left or right side of the vehicle body, so they have to get off to check. At this time, if they park at the wrong position of the gas dispenser, it will be even more embarrassing. In fact, you can easily determine the position of the fuel tank mouth without getting off. In addition, if it is a Japanese Korean system, its fuel tank port is generally located on the left side of the vehicle body; If it is a European American system, the fuel tank port is basically located on the right side of the vehicle body.
Child safety lock
For drivers with children, fear is that children are in danger in the car. Many parents may not know that the rear row of the car is equipped with a child safety lock. After locking, the door cannot be opened from the inside, effectively preventing children from opening the door by mistake. The child safety lock is used for the rear door of the vehicle to prevent the danger caused by opening the door from the vehicle during driving. When this device works, even if the electronic central control door lock is opened, the device is still locked.
