Precautions for driving through a tunnel include slowing down and turning on lights before entering, observing road signs, avoiding the use of high beams, and not stopping randomly in the tunnel. Drivers should react according to actual conditions to prevent accidents. Slow down and turn on lights before entering the tunnel: If driving during the day, the light will suddenly dim upon entering the tunnel, making it difficult for the human eye to adapt quickly. Therefore, before entering the tunnel, drivers should reduce speed, increase following distance, and turn on their headlights to enter the tunnel safely at a slower speed. Most tunnels have clear speed limit signs, so drivers should follow the posted speed limits. Observe road signs: Tunnel entrances usually have large signs. Drivers should choose the appropriate lane in advance before entering. Inside the tunnel, lanes are marked with solid white lines, and overtaking is prohibited. Avoid using high beams: Using high beams for extended periods at night can affect oncoming and leading vehicles, as high beams can temporarily blind other drivers. Inside the tunnel, the contrast between light and dark already strains the driver's vision. Adding high beams increases the risk of danger, so they should be avoided in tunnels. Do not stop randomly in the tunnel: Some drivers may pull over immediately if they encounter a problem, but this habit must be avoided in tunnels to prevent chain-reaction collisions.

Why does the car shake when driving on the highway?

Highway car shaking can be caused by excessive tire pressure, severe tire wear, imbalance in tire dynamic balance, or inaccurate four-wheel alignment. Specific details are as follows: 1. Excessive tire pressure: If the tire pressure is too high, the vehicle will bounce more when driving on bumpy roads, and it can also cause the car body to shake at high speeds. 2. Severe tire wear: If the tires are severely worn with uneven tread, it can also lead to car body shaking at high speeds. In such cases, the tires should be repaired or replaced promptly. 3. Imbalance in tire dynamic balance: If the dynamic balance weights are displaced or fall off, the tires will lose balance, causing the car to shake at high speeds. In this situation, the dynamic balance weights should be inspected and replaced.

Does the BMW X1 have a particulate filter?

The BMW X1 is equipped with a particulate filter. There are 4 models of the BMW X1, all of which come with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they enter the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipe. The densely arranged bag-type filter inside captures the carbon particles on a metal fiber felt filter. When the amount of captured particles reaches a certain level, the burner at the end automatically ignites, burning off the carbon particles and converting them into harmless carbon dioxide. To check if the BMW X1 has a particulate filter, you can use the following 3 methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe for a cylindrical section. If present, that is the particulate filter.

How to Deal with Transmission Failure in Baojun 510?

Solutions for transmission failure in Baojun 510: 1. Difficulty in shifting gears and jerking sensation: During starting or driving, shifting, engaging, or disengaging gears feels stiff and laborious, as if stuck by something, accompanied by jerking, vibration, and a sense of hesitation. Sometimes, shifting is easier when the car is cold but harder when it's hot, causing significant discomfort. Solution: The relevant gears and components inside the transmission are not sufficiently lubricated. Lubricating them should resolve the issue. 2. Warning light illuminated: A warning light shaped like a gear with an exclamation mark inside will appear on the dashboard, and the transmission will enter an emergency mode, meaning it will be locked in 3rd gear, and other gears will be unavailable. Solution: Reset the gear position by restarting the car.
