The most basic function of the interior rearview mirror is to observe rear passengers, especially children in the back seat. The interior rearview mirror can also be used to judge distance between vehicles, assist in turning, and observe vehicles behind during emergency braking. Specific functions are as follows: 1. Judging distance: Maintaining a proper distance from other vehicles while driving can significantly reduce the occurrence of traffic accidents. However, sometimes the exterior rearview mirrors cannot clearly display the distance of vehicles behind. The interior rearview mirror allows for a clearer judgment, enhancing safety. 2. Turning assistance: When preparing to overtake or change lanes, drivers usually turn on the turn signal first and then observe the vehicles behind through the interior rearview mirror. After assessing the driving conditions of the rear vehicles, they can safely change lanes. 3. Emergency braking: Rear-end collisions are common issues during driving. If the vehicle ahead brakes suddenly, the driver must react promptly. At this time, the interior rearview mirror can be used to observe the vehicles behind and adjust the driving distance based on their movement, effectively avoiding rear-end collisions.

What does the vehicle button A mean?

Vehicle button A is the brake assist system, which assists the anti-lock braking system. When the seat belt is properly used, pressing this button can automatically apply the brakes when a temporary stop is needed, preventing the vehicle from rolling when the brake pedal is released. To start driving the car, simply lightly press the accelerator pedal to release the brake and continue moving forward. The brake assist system detects situations encountered while driving based on the speed at which the driver presses the brake pedal. When the driver quickly presses the brake pedal in an emergency but with insufficient force, this system will assist and increase the braking force to the maximum within less than a second, reducing the braking distance in emergency situations.

What Causes Water in the Exhaust Pipe in Winter?

In winter, water in the exhaust pipe is caused by the following: engine exhaust contains water vapor, which condenses into small water droplets when it encounters cold temperatures. These droplets accumulate in the exhaust pipe and are expelled when accelerating due to the exhaust pressure. Lower temperatures in winter make condensation more likely. Generally, the condition of the engine can be reflected by the state of the exhaust from the exhaust pipe. The exhaust system includes the front and rear exhaust pipes. The water droplets expelled from the exhaust pipe are the result of water vapor generated from gasoline combustion condensing in the exhaust pipe and muffler. When the ambient temperature is high, the water vapor is expelled before it can condense. However, when the ambient temperature is low, the water vapor condenses into droplets on the exhaust pipe walls and is expelled with the exhaust flow.
