What does it mean when the vehicle battery indicator light turns red?

Generally, this indicator light on the dashboard will illuminate in cases of alternator failure (or loose belt) or when the engine is not running, signaling that the alternator is malfunctioning or not operating. Below are specific details about automotive batteries: 1. Warranty Period: The typical warranty period for car batteries is 2-3 years. For car owners who pay great attention to vehicle maintenance and particularly battery care, the battery can generally last 4-5 years. 2. Charging Methods: Start the car at regular intervals to charge the battery. Another method is to disconnect the two terminals on the battery. It's important to note that when removing the positive and negative terminal cables from the battery posts, the negative cable should be disconnected first, or the connection between the negative terminal and the car chassis should be removed. Then, disconnect the other end marked with the positive sign (+). Batteries have a certain lifespan and need to be replaced after a certain period. When replacing, the same sequence should be followed, but when reconnecting the terminal cables, the order is reversed: connect the positive terminal first, then the negative terminal.

How to Calculate Fuel Consumption Formula and Cost per Kilometer?

Fuel consumed ÷ Distance traveled × 100 = Fuel consumption per 100 kilometers; The data on fuel consumed is relatively difficult to obtain. Generally, a full fuel tank is used as the initial data. After driving a certain distance, the tank is refilled to full, and the refueling data provided by the gas station is taken as the standard. Below are the specific steps for calculating fuel consumption: 1. Method: First, fill the vehicle's fuel tank to full, then reset the odometer to zero, and proceed to drive. After driving 200 kilometers, enter a gas station to refuel. When the tank is full, the fuel dispenser shows 15 liters. According to the formula (15 ÷ 200 × 100 = 7.5), the vehicle's fuel consumption per 100 kilometers is 7.5L. 2. Notes: Individual driving habits, road conditions, vehicle load, tire pressure, and weather conditions can all affect fuel consumption, making it vary. A more scientific method for calculating fuel consumption involves calculating the average. Drive the vehicle for 10,000 kilometers, record the data after multiple refueling sessions during this period, then take the average of the highest and lowest fuel consumption values. This method yields relatively more scientific data.

Are exhibition cars available for sale?

Exhibition cars can be sold. The display cars in 4S stores are brand new vehicles, placed in the showroom solely for the purpose of allowing customers to get a close look at the models. Apart from being driven into the showroom, exhibition cars are no different from new cars stored in the warehouse. However, since many people sit in and touch them daily, to maintain the showroom's image and customer experience, these cars are cleaned and polished every day. In some ways, their condition might even be better than those stored in the warehouse. If you're considering a purchase, check the manufacturing date to confirm whether it's a stock vehicle. Exhibition cars have a stipulated replacement period, after which they need to be updated. The replaced demonstration cars are not taken back by the manufacturer; they are vehicles purchased by the 4S store itself, which handles their disposal. However, since exhibition cars are already registered and have some mileage, they can only be sold as used cars. Being used cars, exhibition cars are significantly cheaper than new ones, with shorter service histories compared to regular used cars. Additionally, buyers can save on purchase taxes and other fees.

What Are the Basic Knowledge Points of Car Maintenance?

Automobiles are prone to issues such as failure to start, steering wheel vibration at high speeds, and heavy steering. Here are the detailed explanations for car maintenance: Failure to Start: First, check whether components like the high-voltage wires have become damp due to rain exposure. If so, dry the damp parts before attempting to start the engine. Next, inspect the spark plugs for damage. If they are damaged, simply replace them with new ones. Also, verify whether the battery voltage is sufficient. Sometimes, leaving the lights on for an extended period can drain the battery. In such cases, shift the car into second gear, press the clutch, and use another vehicle to tow-start it. Steering Wheel Vibration at High Speeds: When driving at high speeds or at a certain high speed, the car may exhibit instability, wobbling, or even steering wheel vibration. If alignment and suspension components are confirmed to be in good condition, the first step should be to perform tire dynamic balancing.

Is the Steering Wheel on the Left or Right in Hong Kong?

Hong Kong's steering wheel is on the right because it follows the British driving style. Below are specific details about Hong Kong's steering wheel: Reason: Hong Kong was originally a British colony and adopted the British driving style. Due to historical conventions, Britain drives on the left side of the road. To facilitate drivers' observation of the road and passenger boarding/alighting, vehicles with the steering wheel on the right are used. Only a few countries like Japan, the UK, and Commonwealth nations follow this driving style, where the steering wheel is on the right. Most countries drive on the right side, with the steering wheel on the left. Usage Perspective: From a usage standpoint, left-side driving was more suited to the travel habits of the time. In the era of cold weapons, whether walking or riding along roads or alleys, moving on the left side was a protective posture, allowing both parties to raise their right arms to draw swords or thrust spears if necessary. Another factor was that people mounted and dismounted horses from the left side, and mounting stones for knights were initially placed on the left side of the road. Moreover, the standard combat stance for knights was holding weapons in the right hand and shields or reins in the left. To conveniently strike opponents coming from the opposite direction, it was natural to stay on the left side of the road.

What to Do If You Don't Have Enough Points on Your Driver's License?

If you don't have enough points on your driver's license, the vehicle owner needs to retake the course and pass the exam. Here are some relevant details about point deductions: 1. According to traffic regulations, within one scoring cycle, one driver's license can be used to deduct points for up to three vehicles, and one vehicle can accept point deductions from up to three driver's licenses. 2. For a Class C driver's license, if all 12 points are deducted, you need to retake the subject one exam. You can only drive on the road after passing the exam. Driving during this period is considered driving without a license, so you cannot drive. For Class A and B driver's licenses, if all 12 points are deducted, they will be directly downgraded. The local traffic management office will revoke the driving qualification for the highest permitted vehicle type and require the downgrade and license replacement within 30 days. 3. For vehicle owners holding Class A or B driver's licenses, if more than 6 points but less than 12 points are deducted during the probation period, the probation period will be extended by one year. The same rule applies to Class C driver's licenses. However, if 12 points are deducted during the probation period, the probationary driving qualification for the permitted vehicle type will be revoked.
