UV radiation is relatively strong inside a car, as standard automotive glass can only block about 19% of UV rays. Below are specific methods to protect against UV radiation in vehicles: 1. Apply UV-blocking security film: UV-blocking security film has four to five times the heat insulation rate of regular tinted film and can block over 90% of UV radiation. Applying front windshield film significantly reduces interior temperature and skin burning sensations while also protecting the dashboard and preventing fading or aging of interior decorations. Additionally, it reduces the frequency of air conditioning use, saving fuel and electricity. 2. Wear sunglasses or long-sleeved shirts: UV exposure can be minimized by wearing sunglasses or long-sleeved shirts. Sunglasses should be from reputable brands with high clarity to accurately distinguish traffic signal colors, ensuring they are suitable for driving. When driving in long-sleeved shirts, it is essential to have the car's air conditioning professionally cleaned to ensure unobstructed vents, keeping the interior naturally cool. This also removes bacteria lingering in the air ducts, eliminates odors, and freshens the air inside the car.

The UV rays in the car are indeed strong, especially when driving in the height of summer. I often feel my skin burning because the sunlight shines directly through the glass. Although the windshield can block some harmful radiation, the side and rear windows may not completely block UVA rays. This means that even if the car interior isn't hot, UV rays are still damaging the skin. I've made it a habit to apply sunscreen before long drives or use a simple sunshade to block direct sunlight. On weekends when taking the family outings, my child sitting in the back seat got their face sunburned, so we installed special window film—it's much better now. On sunny days, UV exposure inside the car can be just as intense as being outdoors, making protective measures essential.

What is Crawl Mode?

Crawl mode, fully known as the Low-Speed Cruise Driving Assist System, is also referred to as the foolproof off-road system. It ensures that the vehicle does not experience wheel slippage or get stuck due to excessive speed. Below are the precautions for using crawl mode: 1. Gear selection: The manual knob increases crawl speed from left to right, with a total of 5 gears. Low speed is suitable for rocky roads, uneven surfaces (downhill), and gravel roads (downhill); medium-low and medium speeds are suitable for uneven surfaces (uphill); medium-high and high speeds are suitable for snow, mud, gravel roads (uphill), sand, muddy roads, uneven surfaces (uphill), and grass. 2. Cancellation conditions: During crawl mode operation, the mode will automatically cancel when shifting to P or N gear, when the four-wheel-drive control switch is in H4, or when a door is opened. The dashboard indicator will flash and then turn off. 3. Usage conditions: Crawl mode cannot operate for extended periods; otherwise, it will automatically cancel. The vehicle should be parked on a safe surface to allow the system to cool down before resuming use.

What does China 3 and China 4 mean?

China 3 and China 4 refer to China's vehicle emission standards, namely National Standard III and National Standard IV. Below are some methods to distinguish between China 3 and China 4 vehicles: 1. Vehicle Registration Certificate: Commonly known as the "Big Green Book," it contains the relevant annotations. 2. Environmental Protection Green Label: Three stars indicate China 3, while four stars indicate China 4. 3. Year Estimation: Since China 3 and China 4 were implemented in specific years, checking the vehicle model's production year can help estimate the standard. Note: The European Union began implementing similar standards in the early 1990s. China's National Standard I was implemented in 2001, so China's emission standards have always been based on the EU standards.
