What does AVH Auto Hold mean?

AVH Auto Hold refers to an automatic braking function. After activating this feature, such as when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic parking brakes. For automatic transmission models, it also reduces the frequent switching between D to N or D to P. Below are specific details about Auto Hold: 1. It simplifies operations by avoiding the use of manual or electronic parking brakes. 2. Traditional handbrakes require the driver to manually release the brake or skillfully coordinate the throttle and clutch for a smooth start on slopes. 3. The Auto Hold function uses a slope sensor to provide precise parking speed control through the controller.

What to Do When There's a Rubber Friction Sound When Turning the Steering Wheel?

When there's a rubber friction sound while turning the steering wheel, it is usually caused by friction interference noise between the dust cover at the bottom of the steering column and the steering column during relative movement. First, check if the dust cover is installed correctly. Additionally, applying a layer of lubricating grease can help eliminate the noise. Below are the reasons for the rubber friction sound when turning the steering wheel: 1. Friction between the steering column and the floor mat. If the abnormal sound comes from below the steering wheel when turning it, inspect the steering column and the car floor mat. An oversized aftermarket floor mat may directly contact the steering column, causing friction as the column rotates. Lack of lubrication can result in friction noise. Applying some lubricating oil can resolve this issue. 2. Clock spring (spiral cable) malfunction. If the sound originates from inside the steering wheel, it is likely due to interference from the clock spring inside the steering wheel. Remove the steering wheel's clock spring and apply some grease to see if the noise persists. If it does, replace the clock spring as it may be damaged. 3. Lack of lubrication in the shock absorber's top bearing. If the abnormal sound comes from outside the car when turning the steering wheel, it might be due to insufficient lubrication in the shock absorber's top bearing. Open the hood and listen to determine if the sound is coming from the shock absorber's top mount. If it is, apply some grease to the bearing. If the noise continues after lubrication, replacement is necessary.

What Causes a Buzzing Sound in the Cabin When the Car is Idling?

If there is a buzzing sound in the cabin when the vehicle is idling, it is highly likely to originate from the hydraulic power steering pump. Normally, the power steering pump produces a buzzing sound during operation, but if it can be heard inside the cabin, it indicates that the power steering fluid is too dirty or there is an issue with the power steering pump. Replacing the power steering fluid requires two people to cooperate—one responsible for turning the steering wheel inside the car while the other replaces the fluid outside. Below are the steps for replacing the power steering fluid: 1. Drain the old fluid from the power steering fluid reservoir and remove it for cleaning. After cleaning, reconnect only the oil supply hose. 2. Extend the return hose of the power steering fluid reservoir and connect it to a container for collecting the old fluid. 3. Place a funnel on the reservoir for easy refilling and open the power steering fluid bottle to prepare for refilling. 4. The person inside the car starts the engine and immediately turns the steering wheel left and right. At the moment the engine starts, the person outside begins adding fluid to the reservoir. The disconnected return hose will continuously expel the old fluid from the entire system and discharge new fluid. 5. Reserve about half a liter of power steering fluid during refilling. When the return hose discharges new fluid, stop refilling and carefully observe the fluid level in the reservoir. When it drops to nearly empty, immediately instruct the person inside the car to turn off the engine. 6. At this point, since the power steering fluid in the reservoir is almost depleted, reconnect the return hose. After reconnecting, add sufficient power steering fluid to the reservoir. At this stage, the replacement of the power steering fluid is complete.

Is the MR20 engine imported?

There is no information indicating that the MR20 engine is a fully imported engine. In other words, all processes from design, casting, processing, heat treatment, assembly, inspection, error testing to the finished product are entirely handled using Japanese technology. Below is some relevant information about the engine: 1. The automobile engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. 2. Automobile engines are categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid motors. Among these, gasoline and diesel engines are both types of reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston motion to output power.

How to solve the misfire detected in cylinder 3 (P0303)?

P0303 detected misfire in cylinder 3. First, check the spark plug, cylinder wire, and ignition coil, and replace the spark plug or ignition coil in time. For the maintenance of engine misfire, sometimes it is not possible to find the problem by only reading the engine data stream, and an oscilloscope is needed to further make a judgment. The following is the relevant content introduction: 1. The factors to consider for ignition include ignition timing, whether the spark plug is working properly, whether the resistance of the high-voltage wire is within the standard range, whether the ignition coil is working properly (whether the power line and signal line are loose). 2. Also check whether the engine control unit is working properly (including the signals provided by CAN data). It is recommended to use instruments for detection as much as possible.

What are the reasons for high car fuel consumption?

Introduction to the reasons for high car fuel consumption: 1. If you notice a significant decrease in the current coasting distance while driving, you should check whether the tire pressure meets the standard. Insufficient tire inflation will also increase fuel consumption. 2. Check the degree of tire wear. If the tires are severely worn, slipping will often occur, increasing fuel consumption. 3. If you hear abnormal noises from the wheels while driving or starting, promptly check whether there are faults in the bearings or braking system. If the wheels do not rotate normally, it will affect the speed and increase fuel consumption. 4. Clutch slipping will cause the engine to lose RPM. If you notice the engine tachometer increasing rapidly during hard acceleration but the vehicle speed increases very slowly, you can determine that the clutch is slipping. 5. When the car has traveled 200,000 to 300,000 kilometers, insufficient cylinder pressure usually occurs, and fuel consumption will increase significantly at this time. 6. If the spark plugs have been used for too long, fuel consumption will also increase. Damaged spark plugs will reduce ignition energy, slow down acceleration, and lead to a noticeable increase in gasoline consumption. 7. When the car's temperature control switch and thermostat are damaged, fuel consumption will increase. This is because damaged temperature control switches and thermostats will lower the water temperature, preventing the carburetor from working properly and leading to poor gasoline atomization.
