Heavy rain? No problem! Tricks to improve vision
You need to know when and how to use the lights
Thirdly, do not use high beams. Under normal weather conditions, when front vision is limited, most drivers will turn on high beams automatically. However, this is not suitable for fog as high beams have a high illumination angle and the light is concentrated. When used in a fog, high beams create a blinding glare for an oncoming vehicle and impede the sighting of hidden dangers on the road!
In general, front and rear windshield de-misting have corresponding buttons and you just need to switch them on when needed. For cars equipped with manual air conditioning, you should turn it on when de-misting. Rear window de-misting relies on resistance heating and involves high power consumption. For most cars, it will be automatically switched off after being turned on for a certain period of time. You can turn it on again if needed.
Is the windshield wiped clean?
This seems to be a very basic issue but it cannot be ignored. As air pollution is undeniably more serious now, when air quality is poor in the northern area, a lot of PM2.5 pollution comes from the oil particles of combustion. These oil particles, together with summertime rubber and vehicle emissions on congested roads make the windshield dirty.
