1. Tiny black dots on the windshield
If you look at the front and rear windshields, you will notice that there are tiny black dots arranged around the glass edges and the area where the rearview mirror is mounted inside. Many people who do not know will mistakenly think that the manufacturer does it for decoration, but in fact the function of these tiny dots is very important.

The first effect is to prevent the sun's ultraviolet rays from affecting the glass adhesive layer attached to the car frame. The second is to create a rough surface to increase the adhesive area, ensuring stability for the glass and the car frame. Finally, it increases aesthetics by covering the adhesive layer.
In addition, the black dots are designed to be larger near the edge of the glass and gradually smaller towards the center, which helps reduce glare for the front seat passenger and helps the driver's eyes focus more on the road ahead instead of on the tiny black dots.
2. Child lock
In many cases, children sitting in the back are often naughty and accidentally open the car door, causing unsafety, even causing accidents for others even when parked. Therefore, to avoid these cases, car manufacturers have integrated child locks in the rear door area.

Because the child lock is usually located on the rear door wall, and is just a small lever or twist lock, many people often do not pay attention to this detail if they rarely carry small children.
Not to mention if the person sitting behind accidentally flips the child lock lever, it will confuse other people and the car owner when they cannot open the door from the inside. Therefore, if you do not know, you should pay more attention to this rarely used but extremely useful function.
3. Auto feature of air conditioner
Many car buyers demand many modern features, including automatic air conditioning systems. The special thing about automatic air conditioning is that it uses temperature and oxygen sensors in the car to maintain the right temperature and air level, as well as detect the amount of oxygen to switch to taking in fresh air or fresh air without having to manually adjust it.

However, many people only use the internal air intake mode during driving. This causes the quality of oxygen inside to decrease, leading to drowsiness, which is unsafe when operating. Therefore, as mentioned above, when using the Auto feature of the car's air conditioner, it will help the space inside the car always have enough air to help the driver stay awake if having to drive continuously for a long time.
4. Remote start
Recently, some new car models launched in the Vietnamese automobile market such as Hyundai Accent, Honda City, Honda Civic, Hyundai Santa Fe, KIA Sorento or Honda CR-V have added the "Remote Start" feature. This feature allows the car owner to start the engine without having to step into the cockpit.

The "Remote Start" feature is useful on hot days. However, because it must be used at a certain distance from the key to the car, many people are reluctant to use it and even forget about the presence of this feature on their car.
Therefore, if your car has a remote start feature, get into the habit of using it to take full advantage of the equipment that the manufacturer has put on the car.
