Various functions of wiper

Everyone knows the role of the wiper, and it must be inseparable from its hard work when driving on rainy days. However, there are still many new drivers who know very little about the specific functions of wipers-how to adjust the wiper frequency? How to spray the wiper water? In addition, many people are unfamiliar with the rear windshield wipers of hatchbacks, SUVs, MPVs and other models, and have no idea how to use them. Now, let's take a look at the various functions of car wipers.
1 Detailed explanation of the wiper upper lever mark

The wiper switches of most models on sale are set on the lever on the right behind the steering wheel, and the styles are all lever type.



Of course, there will still be some unique designs, such as GAC Fiat Feixiang and Mercedes-Benz models. The position of the wiper switch is different from other models. It is set on the left lever.
The wiper lever is the same as the headlight lever, with many functional logos printed on it. Although the logos and logo positions of different brands are different, the functions are actually the same.
The automatic intermittent working gear of the wiper of certain models can adjust the swing frequency, so that the wiper swing frequency is different according to the speed of the car-when the wiper lever is placed in the "automatic intermittent swing" gear, the wiper will operate The swing frequency will be changed according to the adjusted frequency and the speed of the car. There are two main types of swing frequency adjustment mechanisms: toggle type and knob type.

● When are the different swing frequencies of the wiper used?

No matter what class of car, its wiper blades will have different swing frequency gears. Different swing gears have their uses, we can choose the appropriate wiper gear according to the actual situation and habits
2 Precautions for water spray wiper
Hatchbacks, SUVs, MPVs and other models that do not have a prominent tail box design will be equipped with rear wipers. This is because these models are affected by the rear spoiler, and the rear windshield is easily soiled by the rolled up sewage or mud.

Therefore, hatchbacks, SUVs, MPVs and other models need to be equipped with rear wipers, and the rear windshield glass should be cleaned at any time to ensure a clear view directly behind.

The rear wiper switch is also set on the wiper lever, and the front wiper mechanism is two independent systems, which can be controlled separately. There are two styles of rear wiper switch, toggle type and knob type.

Compared with the front wiper, the function of the rear wiper is much simpler, with only a single oscillation frequency and water spray function.

● Precautions for using wipers when driving

When the wiper is swinging, its impact on the driver's line of sight is inevitable. For novices, how to reduce the interference of the wiper on their driving vision is a driving skill that must be learned.

In addition, when a novice is driving on a stop-and-go congested road, try not to operate the wiper frequently, so as to avoid car collisions caused by distracted operation.

When we operate the water spray function of the wiper, if we find that there is no wiper water spraying, then we should first check whether the nozzle is blocked, and then check whether the wiper water is sufficient.

There is one more thing to note, that is, do not let the wiper wipe the glass (that is, let the wiper swing when the glass is dry)-if the wiper strip is aging and hardened, or there are a lot of sand and foreign matter attached to the windshield, The wiper can easily scratch the glass and cause irreparable damage.

Summary: Understand clearly the function and purpose of the wiper, we can face it calmly when driving on rainy days, and will not be in a hurry. Many drivers ignore the field of vision directly behind the rear windshield, and only rely on the left and right exterior mirrors to observe the rear of the vehicle. Lack of the frontal field of vision will increase the number of blind spots in the rear of the vehicle, which will bring a lot of safety hazards to driving.

So, if your car is equipped with a rear wiper, then you shouldn’t leave it in the cold. After all, the vehicle’s direct rear vision is also very important to prevent you from reversing, hitting a tree, hitting a pillar, hitting people, or being rear-ended by a car behind. But the tragedy of waiting cannot be discovered in time.
