No. Because the manufacturer will consider it as man-made damage, so refuse the warranty. BYD's battery warranty policy is as follows: 1. Lifetime warranty: At present, BYD's battery warranty policy is that the first individual owner (non-operating) has a lifetime warranty for the three-electric system, while the warranty policy for the whole vehicle is 6 years or 150,000 kilometers. For the three-electric system, BYD provides a lifetime warranty. 2. Battery replacement: According to BYD's three-guarantee regulations, the battery can only be replaced free of charge when the battery attenuation is abnormal. As for the standard of this decline, BYD has not yet given an official calculation method, and the state has not formulated relevant regulations. At present, the most common saying in the industry is that if the attenuation exceeds 30%, it will be replaced free of charge.

Can a C2 license drive manual or automatic transmission vehicles?

C2 is for automatic transmission. Here is some knowledge about the differences between manual and automatic transmissions: Different transmissions: Manual transmission vehicles are equipped with manual gearboxes, while automatic transmission vehicles have automatic gearboxes - this is the most fundamental difference between them. Different levels of driving difficulty: Manual transmission requires the driver to coordinate the clutch and manually shift gears according to driving speed. Automatic transmission only requires controlling the accelerator and brake during driving, without needing to shift gears as the system will automatically change gears based on driving speed. Different braking methods: Manual transmission vehicles can decelerate through methods like foot braking and gear shifting, while automatic transmission vehicles decelerate by pressing the brake pedal.

How to Start an Electric Motorcycle?

Take out the vehicle's remote control, locate the unlock button on it, and press this unlock button with your finger. Insert the vehicle's key and turn it to the 'on' position to start the motorcycle. Precautions: During the starting process, do not twist the throttle of the vehicle. Always unlock first before turning the key. Fully Charge Before Use: Since many electric vehicles have been sitting in stores for several months or even over half a year, they must be fully charged before use. After charging, it's best not to use the vehicle immediately; let it sit for about ten minutes. When charging the battery separately, ensure it is securely installed on the electric bicycle to prevent damage from vibrations while riding.

What causes severe shaking when holding the brake in D gear?

It is most likely caused by damaged engine mounts. Severe clutch wear: When stopping in D gear, slippage can also occur because wear reduces the friction between the two. Sliding friction generates abnormal vibrations and rapidly increases the clutch temperature. Therefore, when stopping in D gear at relatively low temperatures, regular resonance or abnormal noises may occur. Torque converter wear: After severe wear, abnormal slippage cannot be ruled out. Additionally, issues such as worn or loose power output shafts, transmission gear or bearing problems, or engine carbon buildup causing idle shaking may contribute. When in D gear, the engine needs to output power, and the RPM will be slightly higher than idle speed. However, if the throttle, intake/exhaust valves, spark plugs, or fuel injectors have severe carbon buildup, air intake, fuel injection, and combustion efficiency will deteriorate at low RPMs.

Why Does a Manual Transmission Car Jerk When Starting?

Manual transmission cars may jerk when starting due to the following reasons: Improper operation: The jerking sensation during startup could be caused by improper operation. Many people experience a couple of jerks when releasing the clutch after engaging the gear. The most direct reasons are releasing the clutch too quickly or not matching it with the throttle. Spark plugs overdue for replacement: Jerking might also occur if the spark plugs are not igniting smoothly. Spark plugs generally need to be replaced every 20,000 to 40,000 kilometers. Transmission clutch slipping: Slipping of the transmission clutch can also cause jerking during startup. Check if there is a burnt smell or excessive dirt in the transmission, and replace the transmission fluid if necessary.

Can halogen headlights be replaced after three years of use?

Halogen headlights can be replaced after 3 years of use. Service life: Ordinary halogen car headlights typically have a service life of only 500 hours. Replacement cycle: With an average daily usage of 2.5 hours, the replacement cycle for headlights is 200 days. Headlights don't necessarily need to be replaced only when they stop working; they should be replaced when the brightness becomes insufficient or dim. Replacement recommendations: More expensive headlights aren't always better. You should choose models suitable for your vehicle. Additionally, xenon headlight modifications have strict requirements for the lighting system wiring. Poor-quality headlights have a short lifespan and cannot guarantee stable quality. High-quality headlights offer good light distribution and high brightness, while inferior ones lack sufficient brightness, poor focus, and short projection distance.

What is the principle of steering when reversing a car?

The steering principle when reversing a car is that the direction in which the steering wheel is turned is the same as the direction in which the tires turn. Below is relevant information about reversing: Precautions: Whether you're a novice or an experienced driver reversing, this is a crucial point to note. Not only should you avoid pressing the accelerator while reversing, but you should also avoid half-pressing the brake. Especially for novices, reversing should be done at a speed slower than idle speed. This allows more time to observe the surrounding environment. Basic essentials: When parking in a parking lot, first, visually estimate the width of the parking space, check for any obstacles behind, whether there are vehicles parked on either side, and whether the length is suitable for your vehicle model. If visibility is poor at night, get out and observe the exact position before reversing.
