wiper
wiper is also called wiper . After years of use, problems such as unclear scraping, squeaking, and rainwater residues often occur. Especially in summer thunderstorms and heavy rainstorms affect driving safety, it is very necessary to replace it in time.
Recommended replacement cycle: 1 year
should spray glass water appropriately before starting the wiper, otherwise it will cause dry scraping. This situation will cause great wear on the wiper, and even scratch the front glass. Wiper blades are consumable parts. If they are not clean, they can be considered for replacement.
Category: Bone Wiper , Boneless Wiper
Wiper 2 Mainly divided into two categories: Bone Wiper wiper and Boneless Wiper. Boneless Wiper wiper is lighter in weight, simpler in structure, and pressure can be evenly transmitted to the wiper rubber strips, which can reduce shaking and wear. Therefore, more and more models are now starting to be equipped with boneless Wiper wipers.
Note the different interfaces of wipers
Of course, the interface part of wipers must also be paid attention to. Among them, U-shaped, snap-button, dovetail and side-plug type account for 99% of the interface types on the market, and only a few of them are the models under Audi A6 and Renault .
When replacing wipers, it is not necessary to use the original wiper brand, as long as the size and interface are suitable for your model.
In addition, in non-4S store channels, car owners can also buy products of the same brand (not the same product of the original car, only the same brand product), but these brand products will not affect the daily use of the car.
What should you pay attention to when replacing wipers?
In fact, there are some tricks to replace the wiper. For example, in many Volkswagen models, you can insert the key and turn it on and turn it to OFF gear, and gently press the wiper gear lever to point the brush mode. At this time, the wiper will automatically hang to the 90° vertical position, which is convenient for changing the wiper .
Prevent the wiper arm from hitting the front glass
After removing the original wiper, be careful not to release the wiper control arm at will. This iron block will directly smash the glass when hitting the front windshield. When replacing, be careful to place protective pads or rags on the glass to prevent accidents.
After talking about wipers, let’s talk about rearview mirror heating.
Rearview Mirror Heating
"Rearview Mirror Heating" function should be familiar with. Many vehicles now are equipped with rearview Mirror Heating function. So what is the function of this rearview Mirror Heating function? And how should I use it?
What is the rearview mirror heating function?
rearview mirror heating means heating the rearview mirror. When driving in rain, snow, fog and other weather, press the rearview mirror heating button. The exterior rearview mirror can be heated by an electric heating wire embedded behind the lens, and then dry the fog and frost on the mirror surface, so as to ensure that the surface of the lens is clear. The function
is not only convenient and saves trouble, but also improves driving safety.
How to heat it with a rearview mirror?
In fact, most models will combine the rearview mirror heating and rear windshield defogging functions on one button, just like the picture below 👇.
That is to say, when the driver presses the rear-glass heating button, the exterior rearview mirror will also heat it together. After turning on it, the heating function will last for 12 to 15 minutes and it will automatically turn off. (This function does not require turning on the air conditioner, it can be turned on and used separately).
Of course, there are also some models of rearview mirror heating functions, which are independently designed on the rearview mirror knob, such as Volkswagen series. This knob of it adjusts the angle of the left and right rearview mirrors. When this knob is in the middle position, the rearview mirror is heated, and the heating function is automatically turned on.
It should be noted here that devices with mechanical structures like this will not automatically turn off after turning on the heating function.
needs to manually twist the knob to the left or right, so as to prevent the heating function from working all the time, which affects the service life of heater .
In addition, there are some more advanced ones. For example, the rearview mirror heating function of BMW car is automatic. The system will determine whether the rearview mirror is heated and how much heated it is based on the current indoor and outdoor temperature difference, as well as whether the wiper is turned on, so there is no separate switch.
What should I pay attention to when using the rearview mirror heating function?
When the rearview mirror heating function is turned on, it will not immediately achieve the effect of defog and defrost, but will gradually eliminate the frost and fog after preheating.
When this function is used too many times, and each time it takes more than 30 minutes, it will affect the life, clarity and luminance of the rearview mirror.
In addition, the heating function of the rearview mirror generally requires the external temperature to be below 20 degrees before it can be activated. When the outside temperature is high, the rearview mirror will not heat up even if the switch is turned on.
rearview mirror heating function is to remove fog and frost on the mirror surface, and cannot eliminate raindrops on the mirror surface in heavy rain environments. Because when it rains heavily, the heat generated by the heating wire is not enough to evaporate the continuous raindrops, it will still cause blurring of the mirror and affect the driver's line of sight.
So, the rearview mirror heating function is not once and for all. For friends who do not have the heating function of the rearview mirror, you can install a rainproof fog film on the rearview mirror of the car. The raindrops will slide off quickly when they touch it, and basically the above effects can be achieved.
Cars with rearview mirror heating function have different rearview mirror lenses from ordinary lenses. The heating lenses have heating function sockets. You must pay attention to this when replacing the rearview lenses.
