When is the toll-free period for highways during holidays?

The toll-free period for highways during holidays starts at 0:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday. The free holidays include four national statutory holidays: Spring Festival, Qingming Festival, Labor Day, and National Day, as well as the consecutive rest days of these statutory holidays as determined by the State Council's official documents in the current year. For ordinary highways, the toll-free period is based on the time when the vehicle passes through the toll lane of the toll station, while for highways, it is based on the time when the vehicle exits the toll lane. The toll-free vehicles include passenger vehicles with 7 seats or fewer (including 7 seats) that travel on toll roads, as well as motorcycles allowed on ordinary toll roads.

What does wheel dynamic balance mean for a car?

The dynamic balance of a car refers to the balance between the wheels when the vehicle is in motion, commonly known as adding balancing weights. A car's wheel is an integrated unit composed of the tire and the rim. However, due to manufacturing imperfections, the mass distribution of this unit may not be perfectly uniform. When the wheel rotates at high speeds, this can lead to dynamic imbalance, causing symptoms such as wheel wobbling and steering wheel vibration during driving. To prevent or correct this condition, weights are added to the wheel while it is in motion to adjust the balance at various edges. This adjustment process is what is commonly referred to as dynamic balancing. New cars undergo dynamic balancing before leaving the factory. However, frequent driving on rough roads can damage the rims or cause tire wear, leading to imbalance over time. Most tire repairs involve removing the tire from the rim, and standard procedures require dynamic balancing after such operations. Additionally, dynamic balancing is theoretically necessary after replacing tires or rims, or installing internal or external tire pressure monitoring systems.

Is a tire pressure of 1.9 normal? Should it be refilled?

A tire pressure of 1.9 is not normal and needs to be refilled, as the normal tire pressure for a car should be between 2.3 and 2.5 bar. When the tire pressure is 1.9, the pressure is significantly low, which could be due to a puncture causing air leakage. It is necessary to go to a repair shop as soon as possible for inspection and handling. If the low tire pressure is caused by a puncture, the tire should be repaired or replaced promptly depending on the situation, and then the tire pressure should be adjusted to the standard level. It could also be a false alarm from the tire pressure monitoring system. In this case, you can use a pressure gauge to check the actual tire pressure. If the actual tire pressure is within the normal range, it indicates an issue with the tire pressure monitor, and the tire can be used normally. Another possibility is slow air leakage from the tire, which may be due to natural aging of the tire or prolonged parking. In this case, simply refill the tire pressure to the normal range.

How to Drive on Sawtooth Road Markings?

Sawtooth road markings should be followed according to the direction indicated on the lane signs. Sawtooth lanes, also known as tidal lanes or variable lanes, refer to lanes with multiple diagonal lines marked on the inner side, allowing the direction of travel to be changed based on real-time traffic flow. Sawtooth lanes are primarily designed for sections where traffic is concentrated during peak hours but lanes are insufficient, or where there is a significant difference in traffic flow between morning and evening peak periods. These lanes are mainly set up at intersections and can be flexibly adjusted according to the characteristics of traffic flow during different time periods, changing the direction of travel to alleviate traffic pressure. They are particularly suitable for intersections requiring time-based traffic management measures.

How to check the engine oil level in an Audi Q5?

Audi Q5 engine oil checking steps: Park the vehicle on level ground, with the engine turned off, pull out the dipstick, wipe it clean, then reinsert it into the oil filler hole. Ensure it is fully inserted, then pull it out again to check the oil level according to the markings on the dipstick. The Audi Q5 is equipped with an EA888 series 2.0T engine. The 4S dealership uses Audi genuine SM-grade fully synthetic engine oil with a viscosity rating of 5W40, requiring 5 liters per oil change. This engine features a high compression ratio which results in elevated internal temperatures. Using higher viscosity oil helps protect the engine, as the oil also serves to cool internal engine components.

How Often Should the Transmission Fluid Be Changed for a BMW 3 Series?

For a BMW 3 Series, the transmission fluid is generally recommended to be changed every 40,000 kilometers or once a year. The purpose of transmission fluid is to form a protective layer on the surface of moving components, separating them from each other. This reduces friction, ensuring smooth operation, and minimizes heat generation and surface wear. Notes for changing transmission fluid: 1. Check the fluid level only when the engine is off, the vehicle is parked on level ground, and the transmission is cold. 2. Remove the filler plug to check the fluid level; the transmission fluid should be at the bottom of the filler hole. 3. If the fluid level is low, add transmission fluid until it begins to overflow from the filler hole, then reinstall the plug.
