Haval Big Dog uses a maintenance-free battery, which does not have an indicator. Its general service life is four years, with an optimal period of two years. If there is a color indicator, it is located at the top of the battery with a small glass window. Green indicates the best condition, blue is good, and red indicates poor condition. More relevant information is as follows: 1. Battery Inspection: Battery inspection mainly focuses on two data points—voltage and starting current. It is best to conduct the inspection when the engine is cold (overnight is even better). The voltage must be higher than 12V. Checking the voltage can be done easily by yourself using a multimeter by touching the positive and negative terminals of the battery. 2. Battery Charge: After replacing the battery, the new battery may not be fully charged, including the original battery in a brand-new car, which might not be at 100% charge. Therefore, after installing a new battery or purchasing a new car, it is advisable to let the engine run for a longer time to ensure the battery is fully charged.

What to Do When the Steering Wheel is Locked?

The solution for a locked steering wheel: First, insert the key and press the brake, then turn the steering wheel left and right. Although the steering wheel is in a locked state, it can be slightly rotated when turning. While turning the wheel, turn the key simultaneously to complete the steering wheel unlocking process. The steering wheel is the wheel-shaped device used to control the direction of the car, and its function is to convert the force applied by the driver on the edge of the steering wheel into torque and transmit it to the steering shaft. The steering transmission shaft serves as a connecting piece between the steering gear and the steering shaft, which facilitates the generalization of the steering gear, compensates for installation errors, and makes the installation of the steering gear and steering wheel in the vehicle more reasonable.

Can private vehicles postpone their annual inspection?

No, the annual inspection of a vehicle can only be conducted in advance but not postponed. Below are the relevant details regarding the annual inspection: 1. Inspection Period: The annual inspection application should be submitted within 90 days (approximately 3 months) before the due date. Additionally, all traffic violations related to the vehicle must be settled before the inspection. If the inspection is not completed by the due date, it will be considered overdue, resulting in a penalty of 3 demerit points and a fine of 200 yuan. 2. Inspection Results: (1) Vehicles that pass the regular inspection will have their driving license and the 'Motor Vehicle Regular Inspection Form' stamped. (2) Vehicles that fail the regular inspection must be repaired within the specified time frame. If they still fail after the deadline, the vehicle management authority has the right to confiscate the license plate and driving license of the unqualified vehicle, rendering it illegal to drive on the road or transfer ownership.

What is the function of the clutch in a car?

The function of the clutch in a car is: 1. Facilitate smooth starting: During startup, the clutch separates the engine from the transmission. There is a slipping phenomenon between the driving and driven parts of the clutch, allowing the torque transmitted by the clutch to gradually increase from zero. This results in a gradual increase in the driving force of the car, enabling a smooth start. 2. Convenient gear shifting: During driving, the clutch is used to separate the engine from the transmission when shifting gears. 3. Prevent excessive stress on the transmission system and damage: During emergency braking, the wheels decelerate rapidly, while the transmission system connected to the engine maintains its original rotational speed due to inertia. This creates an inertial torque in the transmission system that is much greater than the engine torque, making the transmission components prone to damage. 4. Reduce torsional vibration impact: The output torque of the engine is usually unstable. The inertia of its own rotating system can reduce torsional vibration, and the damping springs in the clutch can mitigate the torsional vibration impact caused by the engine, thereby extending the lifespan of the transmission gears.

What are the gear positions of motor vehicles?

Here is an introduction to the gear positions of motor vehicles: 1. All gear positions: Automatic transmissions have P, R, N, D, 2 or S, and L or 1. 2. Parking gear: P stands for Parking gear, also known as the parking position. 3. Other gear positions: R is Reverse, N is Neutral, D is Drive, also known as the driving position. 4. Sport mode: S or 2 represents Sport mode. 5. Low gear: L or 1 is Low gear, also known as first gear. Here is additional information related to gear shifting: 1. Gear shifting: When switching to this gear, the transmission can shift freely, but there will be a delay in shifting, keeping the engine at high RPM for a longer time, allowing the vehicle to move at a low gear with high RPM for an extended period, thereby achieving greater torque output and acceleration. 2. Upshifting technique: The key to smooth upshifting lies in the "throttle blip" magnitude. The "throttle blip" distance should be determined based on the gear being shifted to—the higher the gear, the longer the "throttle blip" distance.

Can License Plates Be Changed?

Whether license plates can be changed depends on the following situations: 1. After registration: The license plate number cannot be changed because current license plates are for life and cannot be bought or sold. The only solution is to transfer the vehicle ownership. After the transfer, you can reapply for registration, at which time you can choose a new number. 2. Before registration: If you have only selected a number online but have not registered it, you can change the license plate number. After selecting a number, the owner should submit the required documents to the vehicle management office within the specified time to apply for registration. If the procedure is not completed within the designated time, the selected number will automatically become invalid and will be returned to the pool of available numbers. Note that there are only three opportunities to change the number.
