Yes. However, AUTO mode does not control high/low beam switching. Automatic headlights rely on sunlight sensors to determine ambient brightness and cannot analyze real-time changes in surrounding conditions to select between high and low beams. If you want automatic control of high beams, you need to push the combination light switch forward to the high beam position and then turn the knob to AUTO position - this will enable automatic high beam activation. The same applies to low beams. When driving conditions become darker, the headlights will automatically turn on, and they'll turn off when light increases. It's worth noting that many people mistakenly believe "automatic headlights" are specifically designed for tunnels. However, this isn't the case. Automatic headlights have an activation delay - they only turn on within several seconds after the light sensor detects darkness. According to traffic regulations, headlights must be turned on before entering tunnels, so you still need to manually activate headlights in advance when passing through tunnels.

How many points are deducted for driving a motor vehicle in the wrong direction on urban roads?

There are two situations for driving a motor vehicle in the wrong direction on urban roads: 1. Driving in the wrong lane is a violation that requires a deduction of 3 points and a fine in RMB. 2. Another situation is driving against traffic restrictions, which also requires a deduction of 3 points and a fine in RMB. According to the Road Traffic Safety Law of the People's Republic of China, the fine for driving a motor vehicle in the wrong direction on urban roads depends on the circumstances, and 3 points will be deducted. In severe cases, the driver's license may be revoked. According to the Road Traffic Safety Law of the People's Republic of China, driving a motor vehicle in the wrong direction refers to the following situations. 1. On roads with solid dividing lines, motor vehicles enter the opposite lane. Among them, roads with double solid lines or single solid lines must not be crossed under any circumstances. 2. On roads with dashed dividing lines, it is possible to borrow the opposite lane to overtake when safety is ensured, but once an accident occurs, the vehicle borrowing the lane will be deemed to be driving in the wrong direction.

Can You Still Drive When the Engine Malfunction Light Comes On?

When the engine malfunction light comes on, you should stop driving immediately to protect the engine. Continuing to drive may cause damage to the engine. With the advancement in automotive manufacturing technology, the engine itself generally does not experience major failures. There are many sensors and electronic devices around the engine, as well as some critical components. If any of these parts malfunction, it may cause the engine to stop working properly, triggering the engine malfunction light. More details are as follows: 1. Sensors around the engine: These include the camshaft position sensor, oxygen sensor, coolant temperature sensor, knock sensor, air flow sensor, intake air temperature sensor, etc. If any of these sensors fail, it may cause the engine to malfunction. During repairs, technicians usually connect a diagnostic computer to the OBD interface to read the vehicle's trouble codes. These codes help technicians quickly identify the faulty part and the cause of the issue. Therefore, reading trouble codes is an essential and mandatory step in vehicle maintenance. 2. If the engine malfunction light comes on: It is recommended to immediately visit the nearest repair shop to diagnose and fix the issue. The vehicle's dashboard also features many other malfunction and warning lights. When these lights illuminate, they indicate a problem in a specific part of the car, and it is important to have it checked promptly.

Is it illegal to hang national flags on both sides of a car?

It is not illegal. However, the flags must be hung in appropriate positions to show respect for the national flag, so caution is necessary. More detailed information is as follows: 1. Hang small national flags, but they must be placed in appropriate positions: This demonstrates respect for the national flag; otherwise, it may have the opposite effect. Therefore, it is crucial to be careful. If there is no suitable position, it is better not to hang them. Alternatively, you can choose to place a national flag sticker on the upper part of the front windshield where it does not obstruct the view. 2. The national flag is a symbolic banner of a country and represents the nation: People often hang national flags to express their love for their own country or respect for other countries. It is prohibited to hoist damaged, soiled, faded, or non-standard national flags. The national flag and its design must not be used as trademarks or in advertisements, nor should they be used in private funeral activities. It is forbidden to intentionally insult the national flag of the People's Republic of China by burning, damaging, scribbling, defiling, trampling, or other means. The national flag must not be hung upside down. Due to the design and text on some national flags, they should not be hung vertically or reversed. Some countries explicitly stipulate that a specially made flag with the design properly oriented must be used for vertical hanging.

How many points are deducted for driving through a red light at an intersection?

Points deduction for running a red light: According to the new traffic regulations, driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. However, not all situations will lead to a 6-point deduction for the driver. 1. If there is a violation such as making a left turn in a straight lane at an intersection, it will still be recorded as 'violation of prohibition signs' under the Road Traffic Safety Law, resulting in a 3-point deduction. Additionally, running a red light captured by cameras will only incur a fine without point deduction. Traffic police explain that since not all motor vehicles are driven by their owners, it is difficult to determine the driver who ran the red light, so for non-on-site penalties for running a red light, no point deduction will be imposed for the time being. 2. When an intersection electronic eye captures the illegal act of running a red light, it generally takes 3 photos as evidence. One photo shows the vehicle before it crosses the stop line during the red light, and the other two photos show the vehicle continuing to move forward during the red light, crossing the stop line and completely entering the intersection. The 3 photos will clearly record the vehicle's movement during the red light. If the vehicle has just crossed the stop line during the red light but stops immediately, the traffic management department will not impose any penalty.

Is it necessary to buy a 4WD CR-V?

CR-V 4WD models are suitable for driving on slippery surfaces such as rain and snow. Below are the specific details about the Honda CR-V: 1. Drivetrain: The Honda CR-V offers two variants: one is a two-wheel-drive (2WD) version, and the other is a four-wheel-drive (4WD) version. The 4WD model uses a front-engine, four-wheel-drive system with an on-demand 4WD configuration. 2. Powertrain: The Honda CR-V is equipped with two i-VTEC engines: a 2.0L and a 2.4L. The 2.0L engine delivers a maximum power output of 114 kW and a peak torque of 190 N·m, while the 2.4L engine produces a maximum power of 140 kW and a peak torque of 222 N·m. 3. VTEC Technology: The Honda CR-V features VTEC engine technology, which stands for Variable Valve Timing and Lift Electronic Control System. Unlike conventional engines, the VTEC engine differs in the number and control method of camshafts and rocker arms, featuring two distinct sets of valve-driving cams for low-to-mid and high-speed ranges. These can be automatically switched via the electronic control system. With the VTEC system, the engine can adjust valve opening timing and lift according to driving conditions, thereby altering intake and exhaust volumes. This enhances power output, reduces fuel consumption, and minimizes emissions.
