Can I Charge My Phone Without Starting the Car?

You can charge your phone without starting the car, but it consumes power from the car battery. Here are some precautions to take when the car is turned off: 1. Avoid long-term charging without starting the car: If there are other power-consuming devices, it's advisable to start the car. Otherwise, prolonged low battery levels can damage the battery, and if the battery is too low, the car may not start. 2. Battery wear: Fully charging your phone while the car is off is not an issue. However, leaving the ignition on means other electrical devices in the car will also remain powered, which can quickly drain the battery and even prevent the car from starting, as well as cause wear on the battery. 3. Automatic power-off: Some cars automatically cut off all power a few minutes after turning off or locking the car to protect the battery. For example, the BMW X1 has this feature. Instead of risking a dead battery or damaging the car battery to charge your phone, it's better to keep a power bank in the car. The battery is simply being drained without any benefit when the car is off, which is not worth the cost.

How to Use the Three Differential Locks on the G-Class?

Each differential lock is used at different times. Differential locks are not needed under the following conditions: driving on straight roads or ordinary roads, where the G-Class is in full-time four-wheel drive mode. Below are the scenarios for activating the three differential locks: 1. Activate Differential Lock 1 (Central Differential Lock): This ensures the front and rear axles rotate at the same speed, suitable for roads with gravel or minor bumps, or slight slopes where single-wheel slippage (either front or rear) may occur. However, it is not suitable for cross-axle conditions. 2. Activate Differential Lock 2 (Rear Differential Lock): This ensures both rear wheels and the front axle rotate at the same speed, suitable for situations where only one rear wheel maintains traction, such as encountering large rocks or severely uneven roads. 3. Activate Differential Lock 3 (Front Differential Lock): This ensures all wheels receive equal power, suitable for extremely harsh conditions where all wheels on one side lose traction or only any single wheel has traction. It is ideal for desert driving or escaping snow traps.

Can four children sit in the back seat of a sedan?

A sedan with a rated capacity of 5 people can only accommodate 3 people in the back seat. Sitting 4 people exceeds the capacity by 20%. For private vehicles, exceeding the rated passenger capacity by more than 20% results in a deduction of 6 points and a fine ranging from 20 to 200 yuan. Here is more related information: Article 55 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates the following for motor vehicles: 1. Passenger vehicles on highways must not exceed the rated passenger capacity, except for children exempted from tickets as per regulations. When the passenger capacity is full, the number of exempted children must not exceed 10% of the rated capacity. 2. The cargo compartment of a freight vehicle must not carry passengers. On urban roads, freight vehicles may carry 1 to 5 temporary workers in the cargo compartment if there is a safe space available. When the height of the cargo exceeds the sides of the compartment, no one may ride on top of the cargo. 3.
