Which days in 2019 are toll-free on highways?

According to the "Implementation Plan for Exempting Small Passenger Vehicles from Toll Fees on Major Holidays", the toll-free periods on highways are applicable during four national statutory holidays: Spring Festival, Tomb-Sweeping Day, Labor Day, and National Day, as well as the consecutive holidays determined by the State Council for these statutory holidays. The toll-free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday. In 2019, the toll-free periods for seven-seat and smaller passenger vehicles on highways are as follows: 1. Spring Festival: According to the lunar calendar, from 00:00 on February 4 (New Year's Eve) to 24:00 on February 10 (the sixth day of the lunar new year), totaling 7 days. 2. Tomb-Sweeping Day: From 00:00 on April 5 to 24:00 on April 7, totaling 3 days. 3. Labor Day: From 00:00 on May 1 to 24:00 on May 3, totaling 3 days. 4. National Day: From 00:00 on October 1 to 24:00 on October 7, totaling 7 days.

How to Reset the Tire Pressure Monitoring on the Verano?

The method to reset the tire pressure monitoring on the Verano is: Switch the small screen on the dashboard to the vehicle information section; Locate the tire pressure information section and select to perform tire pressure learning; Deflate the tires until you hear the horn sound, and the turn signal on the current tire side turns off while the right turn signal lights up. The deflation sequence should be: front left, front right, rear right, rear left; Observe the tire pressure status of each tire on the dashboard to ensure the pressure is within the normal range of 2.3 to 2.5. Tire pressure refers to the air pressure inside the tire. When the tire pressure is too high, the vehicle's rolling resistance is low, and fuel consumption is reduced, but in emergency situations, hard braking may fail to stop the vehicle promptly, or the braking distance may increase; When the tire pressure is too low, the vehicle's comfort improves, providing a quiet and smooth ride, but rolling resistance increases, leading to higher fuel consumption. Additionally, the vehicle is more prone to standing waves and sudden tire blowouts at high speeds.

What are the causes of the HAVAL H6 hill descent control failure?

HAVAL H6 hill descent control failure reasons are as follows: 1. Fault in PT-CAN related wiring or a certain node: Using a fault detection device, it was found that the electronic parking brake control module (EPB) stored one current fault code: "U111281 ESP CAN signal failure." The electronic stability program control module (ESP) also stored one current fault code: "U100104 CAN passive error." The engine control module (ECM) stored two historical fault codes: "U01018 Communication with TCU" and "U012687 Lost communication with SAS"; no fault codes were stored in other modules. Analyzing the fault codes, it is inferred that there is a fault in the PT-CAN related wiring or a certain node. 2. Virtual connection in the gateway internal circuit leading to low network voltage: When HDC is set and the vehicle enters a steep slope, engine braking itself can provide a considerable degree of deceleration effect without the risk of tire lockup. When the steep slope gradient is too large and engine braking is insufficient to maintain the speed limit, HDC can use the ABS system to reduce the gradually increasing speed, maintaining a stable and safe speed downhill. If the driver needs to steer to avoid obstacles during the steep descent, the HDC system will detect this and further reduce the speed limit to 6.4 km/h to ensure complete vehicle control.

What Causes the Car Tire Pressure Light to Illuminate?

The reasons for the car tire pressure light to illuminate are as follows: 1. Punctured tire: A slow leak caused by a puncture may trigger the tire pressure monitoring light, making it difficult to immediately identify which tire is affected. In this case, use a tire pressure gauge to measure the pressure (recommended: front 2.3, rear 2.5). If the pressure is low, inflate the tire and then monitor the warning light. If it illuminates again after a few days, a tire removal inspection may be necessary. 2. Overinflated tire: The tire pressure monitoring light may also illuminate due to excessive tire pressure. According to the international GBT2978-2008 standard, the recommended inflation pressures are: standard tires: 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; maximum pressure: should not exceed 3.5 bar. Therefore, if any tire exceeds 3.0 bar, the tire pressure monitoring light may activate. 3. Prolonged driving with low tire pressure: Extended driving with insufficient tire pressure can cause the tire temperature to rise during high-speed operation, leading to increased tire pressure and triggering the warning light. In such cases, it is advisable to stop and rest or replace the tire with a spare promptly.

What does the traffic sign 30t mean?

The sign 30t indicates a weight limit, meaning that the maximum weight of passing vehicles should not exceed 30 tons. During road construction, due to material limitations, regional constraints (such as saline-alkali land or wetlands), and road environment restrictions (such as tunnels on lower-grade roads), it is necessary to control vehicle weight and speed. This is both a protection for the road and for the safety of vehicle occupants. Other traffic signs: Warning signs: These are used at specific road sections or locations to alert drivers and pedestrians to potential hazards. Warning signs are shaped as equilateral triangles with the apex pointing upward. They are yellow with black borders and black symbols. Most feature internal symbols, though a few may be cross-shaped or have diagonal bars. There are up to 48 types of warning messages. Prohibition signs: These signs prohibit or restrict certain traffic behaviors of vehicles, regulating, guiding, and controlling traffic flow and direction. They come in circular or inverted equilateral triangle shapes, with some using hexagonal designs. They have a white background, red borders, red bars, and black symbols, with the symbols overlaid on the bars. Directional signs: These indicate how vehicles and pedestrians should proceed. They come in circular, rectangular, or square shapes, all with a blue background and white symbols. Guide signs: These provide information about road direction and distance, and can be categorized into general road guide signs and highway guide signs.

Does Increasing Air Intake Enhance Car Performance?

Increasing the air intake in a car can enhance performance because a larger air intake volume results in a leaner air-fuel mixture. The oxygen sensor on the exhaust pipe detects this change and adjusts the fuel injection to maintain normal emissions. Methods to Enhance Car Performance: Engine Modification: The most effective way to boost performance is by upgrading the ECU program. This modification can alter the engine's ignition timing, fuel injection timing, RPM limit, torque limit, and more, enabling the engine to operate more efficiently. Ignition System Modification: The ignition system is a critical component of the engine, comprising the power source, ignition trigger signal, ignition timing control signal, high-voltage ignition coil, high-voltage wires, and spark plugs. The quality of ignition performance and the timing of ignition significantly affect fuel combustion efficiency, indirectly influencing engine power. Therefore, modifying the ignition system primarily aims to address the shortcomings of the original system, focusing on precise ignition timing, increasing ignition intensity, extending ignition duration, and reducing voltage transmission losses. Air Intake Modification: There are several methods to modify the air intake system. Installing a high-performance intake manifold is a highly effective approach. Original intake manifolds are typically cast, featuring rough inner walls and noticeable mold lines, which negatively impact intake efficiency and airflow smoothness. High-performance intake manifolds have smoother inner walls, improving intake efficiency without losses. Additionally, upgrading to a mushroom-style air filter and installing an intake turbo in the intake hose are both effective and cost-efficient modification methods.
