New car tires should be replaced every 3 to 5 years or after driving 60,000 to 80,000 kilometers. The method to determine whether tires need replacement is to check their wear level. Tires should be promptly replaced when the tread depth falls below 1.6mm; when tires have been in use for over 5 years and the sidewalls are covered with cracks; or when a tire has been punctured more than 4 times or the puncture hole diameter exceeds 6mm. The functions of tires are: 1. To support the vehicle load; 2. To reduce and absorb vibrations and impact forces during driving, preventing severe vibrations from damaging car components; 3. To transmit driving force, braking force, and steering force, enabling vehicle operation.

Where is the auxiliary battery of Mercedes-Benz located?

Mercedes-Benz's auxiliary battery is located on the right side of the trunk. The auxiliary battery is an important component in the vehicle, responsible for powering all electronic devices in the car and also for starting the engine. When the car's alternator is not generating electricity or the voltage is very low, the electrical energy required by the engine ignition system and the vehicle's electrical equipment is entirely supplied by the auxiliary battery. The battery is a wear-prone component that requires frequent replacement. Avoid sitting in the car for extended periods using electronic devices without starting the engine. When parking overnight in winter, try to avoid leaving the car outside all night. If the car is not driven for a long time, the negative terminal of the battery can be disconnected to prevent battery discharge.

Is Mercedes-Benz's 4matic a four-wheel drive system?

Mercedes-Benz's 4matic is indeed a four-wheel drive system. Models with the 4matic badge on the rear are equipped with this system, which is a full-time four-wheel drive system. Vehicles with full-time four-wheel drive always have power distributed to all four wheels, improving mechanical grip, handling, and driving stability. Part-time four-wheel drive systems are typically used only in rugged off-road vehicles. Vehicles equipped with part-time four-wheel drive have three modes: high-range four-wheel drive, low-range four-wheel drive, and high-range two-wheel drive. When switched to low-range four-wheel drive mode, the vehicle's wheel torque increases, enhancing its off-road capability and ability to escape difficult terrain.

Will the malfunction light come on if the ignition coil is broken?

The malfunction light will come on if the ignition coil is broken, and it is best to go to a 4S shop for inspection. The following is an introduction to engine-related content: Energy conversion: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. Device: An engine can refer to both a power generation device and the entire machine including the power device (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of the engine also originates from English, and its original meaning refers to "a mechanical device that generates power."
