BYD cannot detect the smart key solution is to place the key close to the start button and wait for the button indicator light to turn green. The following are the reasons why BYD cannot detect the key: 1. Key placement position: in the trunk or on the floor of the car, cup holder, glove box, storage box on the door trim panel, near the rear shelf, under the front windshield, etc. 2. Insufficient key battery: The remote key uses a regular button battery with a rated working voltage of 3.3V and a service life of 2 years. 3. Key case: Causes weak or blocked signals. 4. Signal interference: Place the key together with devices such as mobile phones, laptops, power adapters, etc. 5. Key chip: Causes poor signal transmission or no transmission at all. 6. Faulty in-car oscillator or related issues: Fails to form an effective electronic oscillation area, thus unable to scan and recognize the key.

What is the correct sequence for a first-time refueling?

Steps for first-time refueling: 1. Determine if refueling is needed by checking the remaining mileage, typically when it falls below 200km (adjust according to actual driving conditions); 2. After deciding to refuel, properly enter the gas station following traffic rules - never stop at station entrances. Park near an unoccupied pump maintaining safe distance; 3. Roll down windows and turn off the engine (never attempt to start the engine during refueling as it's extremely hazardous); 4. Open the fuel tank valve (a mandatory pre-refueling step - familiarize yourself with this procedure to avoid inconveniencing attendants); 5. Inform the attendant about your fuel type preference (regular/premium), specify either monetary amount or request full tank. After refueling, ensure the fuel cap is securely closed before restarting the engine.

What is the fuel consumption of the Volkswagen T-Cross?

The combined fuel consumption of the Volkswagen T-Cross is 5.7-5.9L/100km. Currently, there are 5 models of the Volkswagen T-Cross available for sale: the DSG Luxury Edition and DSG Comfort Edition, with a combined fuel consumption of 5.7L/100km. The Manual Trend Edition, Automatic Comfort Edition, and Automatic Trend Edition have a combined fuel consumption of 5.9L/100km. The above figures are the NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 7.0-8.8L/100km. Specific factors affecting car fuel consumption are as follows: Car weight: Larger and heavier cars consume more fuel. Generally, a small family car with a 1.6L engine weighs about 1.2 tons and consumes approximately 7.5 liters of fuel (calculated under full load), while an SUV weighing about 1.5 tons consumes around 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag increases fuel consumption during driving. Cars with better aerodynamics have lower drag, leading to lower fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point. Maintaining the car's speed within this range significantly reduces fuel consumption. Generally, small-displacement cars achieve this at about 70 km/h, while larger-displacement cars reach it at around 100 km/h. Staying within this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light can increase fuel consumption.

How long after the expiration of the vehicle annual inspection can the car not be inspected?

If the vehicle annual inspection expires for three cycles, the vehicle will be deregistered and cannot be inspected. For example: if the vehicle inspection expires on January 1, 2013, and there is no inspection for three consecutive years (2013, 2014, 2015), the vehicle will be deregistered after January 1, 2015. Before exceeding three cycles, being caught by traffic police, or causing an accident, it is fine to rush for a supplementary inspection. Driving without inspection is illegal. The vehicle annual inspection must not exceed the month of the registration date, meaning it must be conducted within the month of the valid registration date on the vehicle license. For example, if the registration date is June 10, the inspection cannot exceed June 30. If the inspection is done on July 1, it will be considered overdue, resulting in a fine and a deduction of 3 points.

What does matrix headlight mean?

Matrix headlight, also known as matrix beam, refers to LED headlights arranged in a matrix pattern. The advantages of matrix LED headlights include: the ability to accurately illuminate the road ahead under various conditions, with each LED light element capable of independent brightness adjustment and on/off control. When encountering oncoming vehicles or pedestrians at night, the matrix LED headlights will automatically turn off certain light units. Through matrix LED headlight technology, it can be observed that better integration of hardware and software helps vehicles achieve improved automation, thereby making driving more convenient and safer for drivers. The disadvantage of matrix headlights is: the system is complex and requires multiple hardware and software components to work together for proper operation.

Can motorcycles go on highways?

Chinese law does not prohibit motorcycles from driving on highways. However, due to speed restrictions, motorcycles with a designed maximum speed below 70 kilometers per hour are not allowed to enter highways, while those with a designed maximum speed exceeding 70 kilometers per hour are permitted. According to Article 67 of the Road Traffic Safety Law of the People's Republic of China: Pedestrians, non-motor vehicles, tractors, wheeled special machinery vehicles, articulated buses, full trailers, and other motor vehicles with a designed maximum speed below 70 kilometers per hour are not allowed to enter highways. The maximum speed limit indicated by highway speed signs must not exceed 120 kilometers per hour. Precautions for motorcycles on highways: When entering a highway, it is mandatory to wear a helmet as stipulated by traffic safety laws. Failure to wear a helmet may result in being stopped and fined by traffic police. Additionally, carrying passengers on highways is strictly prohibited. The speed of a motorcycle must not exceed 80 kilometers per hour, and it must be driven on the right side of the road, maintaining a speed between 70 and 80 kilometers per hour. While driving, motorcycles must stay on the right side of the lane. Changing lanes arbitrarily or occupying other vehicles' lanes may also lead to penalties.
