Solutions for a dead battery are as follows: 1. Replace the vehicle's battery; 2. Use an emergency power source to start the vehicle; 3. Alternatively, start the vehicle by jump-starting it. Below is an introduction to the jump-starting method: 1. First, prepare two jumper cables. 2. Then, find a vehicle that can operate normally and position the front ends of both vehicles facing each other. 3. Secure the jumper cables to the batteries, connecting positive to positive and negative to negative, then start the functioning vehicle. 4. Next, start the vehicle that needs the jump-start, and quickly disconnect the cables once it starts to complete the jump-start process.

A dead battery is the most common reason for a car not starting, something I often encountered when I was younger, especially more noticeable in winter. Battery aging or leaving lights on can drain the power, particularly for old batteries over three years old. The solution is simple: first, find someone to drive over and jump-start your car. Prepare two cables, attach the red one to the positive terminal (the + sign on the battery) and the black one to the negative terminal (the - sign). Connect the cables to the assisting car first, then to your car to avoid short-circuit sparks. After starting, let the engine run for 20 minutes to recharge. For prevention: regularly check the battery's date label, and replace it if it's expired or frequently dead. Opt for AGM or EFB types for better durability. Before long trips, test the voltage—it's best to have it above 12.6V to prevent unexpected issues.

Why is the reversing camera image upside down?

The reversal of the reversing camera image is mostly due to the front and rear cameras being installed incorrectly. Below is a detailed introduction to the meanings of different colored trajectory lines in reversing cameras: 1. Red trajectory: Indicates a warning line, with a distance of 30cm from the rear of the car. When the car approaches this line, the parking space is just right, and no further reversing is allowed. 2. Yellow trajectory: Indicates a deceleration line, with a distance of 60cm from the rear of the car. You can continue to reverse, but pay attention to deceleration and check the distance. 3. Green trajectory: Indicates a normal safety line, where the distance between the obstacle and the rear of the car is relatively large, allowing you to reverse with confidence.

Why is the steering wheel crooked?

The main reasons for a crooked steering wheel are: 1. The installation between the vehicle's steering wheels, steering knuckles, and front axle has a certain relative position. If this relative position changes due to external forces, the vehicle may pull to one side. 2. The vehicle's suspension or body may have been deformed due to impact. 3. A flat or underinflated tire can also cause the vehicle to pull to one side. Here is some additional information: 1. Introduction: The steering wheel is the wheel-shaped device used to control the direction of a car. 2. Function: It converts the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft.
