Car spare tires typically have a lifespan of about four years. Below is a detailed introduction to the types of car spare tires: 1. Full-size spare tire: A full-size spare tire has the exact same specifications as the other four tires on the vehicle, allowing it to replace any temporarily or completely unusable tire. 2. Non-full-size spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary use. It should only be installed on non-driving wheels, and the maximum speed should not exceed 80 km/h. 3. Run-flat tire: Also known as a safety tire or commonly referred to as a 'run-flat tire,' it differs from regular tires in that it does not lose air or loses air very slowly when punctured. This allows the vehicle to continue driving normally, and the tire bead remains securely fixed to the rim, ensuring the car can drive to a service station either over a long distance or temporarily.

How to turn off the S indicator on the Mercedes dashboard?

Mercedes dashboard displaying S can be turned off using the mode switch located below the gear lever. The S gear represents the car's sport mode, where the vehicle's performance is fully highlighted in this mode: the suspension becomes stiffer with stronger support, the throttle responds more quickly, the engine intake increases, and acceleration becomes very rapid, though fuel consumption also increases significantly. Generally, only performance cars have this mode. Since the S gear only delays upshifting without altering other operational aspects, it inevitably increases the transmission load and temperature in the short term, leading to accelerated wear. Therefore, it is advisable not to use the S gear for extended periods. Mercedes-Benz is a German luxury car brand, the inventor of the automobile, and is considered one of the world's most successful premium car brands.

Can the battery be charged immediately after adding water?

The battery cannot be charged immediately after adding water. It needs to stand for 1 to 2 hours before charging to allow the added distilled water and sulfuric acid to diffuse and mix. The battery, also known as an accumulator, is a device that converts chemical energy into electrical energy. Its function is to supply power to the engine. When the vehicle is about to start, the battery discharges to provide power to the starter, which then drives the flywheel and crankshaft to start the vehicle.

What are the reasons for the windshield wiper not spraying water?

There are several reasons why a vehicle's windshield wiper may not spray water: 1. Insufficient washer fluid level - some vehicles will illuminate a dashboard warning light when the washer fluid is low, reminding the driver to refill it; 2. Incorrect washer fluid selection causing freezing in cold weather, which may crack the washer fluid reservoir - always choose antifreeze-type washer fluid; 3. Malfunction of the washer pump preventing normal operation.
