How to Steer When Reversing into the Right Parking Space?

When reversing, observe the edge line of the parking area. Once it is fully visible below the left rearview mirror frame, start turning the steering wheel all the way. Turn the steering wheel in the direction you are reversing, then check the side mirrors—use the left mirror for left-side parking and the right mirror for right-side parking. The car will enter the parking space. When the car body is almost parallel to the parking lines, quickly straighten the steering wheel.

Will the Mercedes-Benz C-Class give a warning when wading through water?

Mercedes-Benz C-Class usually gives a warning with the engine fault light when wading through water. Here are some precautions for driving through water: 1. Determine the depth of the water: If the water does not exceed half the height of the wheels, it is safe to drive; otherwise, it is not recommended to continue driving. 2. Use snow mode: After entering a waterlogged section, slow down and drive carefully. For automatic transmission cars, try to use first gear and preferably enter snow mode to prevent wheel slippage. 3. Continuous braking: After exiting the waterlogged section, brake several times in succession to evaporate the water in the brake discs to avoid affecting the vehicle's braking performance.

What could be the issue when the Baojun 630 fails to start?

Baojun 630 failing to start could be due to: 1. When starting, only the electromagnetic switch of the starter makes a 'clicking' sound, or during the first attempt, the starter slowly turns the crankshaft a few times, followed by the electromagnetic switch clicking again, but the crankshaft does not rotate. This phenomenon is usually caused by a 'broken grid' fault in the battery. 2. The car starts every time after a temporary stop, but when parked for a longer time or the next day, it only manages to turn the crankshaft once. This indicates severe self-discharge of the battery, with its plates and separators heavily aged, suggesting the battery is nearing the end of its life. 3. If the starter suddenly lacks power during startup, accompanied by a burning rubber smell or smoke from the battery area, it is mostly due to poor contact at the terminal posts or clamps, leading to overheating and damage.
