Cars exposed to the sun in summer have an extremely low possibility of gasoline evaporation, as the fuel tank cap is sealed with a rubber gasket, and the fuel pipe is connected to the engine, which is also sealed. More details are as follows: 1. Gasoline in a sun-exposed car: Gasoline in a sun-exposed car will not evaporate from the fuel tank, but it may deteriorate, potentially producing excessive gum and carbon deposits in the intake system, which can affect the normal operation of the engine; 2. Introduction to gasoline: Gasoline is an industrial oil product that is very volatile. Gasoline added to a car's fuel tank is generally well sealed and not prone to evaporation. If the fuel tank's sealing is poor, it may evaporate to some extent; 3. Summer precautions: Summer temperatures are relatively high, so it is recommended not to park the car in direct sunlight, as this can damage the gasoline pipelines.

What are the reasons for the car rolling when in P gear?

The reasons for the car rolling when in P gear are: 1. The driver did not step on the brake or pull the handbrake, causing the vehicle to roll due to inertia; 2. Insufficient power when the car is idling or in neutral, or the slope is too steep, leading to the vehicle rolling when in D gear due to lack of power; 3. Delayed power response when releasing the brake and stepping on the accelerator, causing the car to roll. Precautions for driving an automatic transmission car are: 1. Do not shift into P gear while driving; 2. After driving, the engine must be turned off and shifted into P gear before the key can be removed; 3. Do not shift into N gear to coast while driving; 4. When starting the vehicle in P or N gear, remove the gear lever from P gear while stepping on the brake, turn on the power, step on the brake, shift to N gear, and after ignition, shift into D gear to move forward directly.

Where is the steering wheel heating in Mercedes-Benz E?

The steering wheel heating in Mercedes-Benz E is located on both sides of the steering wheel. There is a small button on the side of each multifunction key, and pushing it inward activates the heating. The function of the steering wheel is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft to control the vehicle. The purpose of the steering wheel heating function is to warm the steering wheel during cold seasons, ensuring the driver does not feel uncomfortable or cold when holding it. The working principle of the steering wheel heating function involves embedding a layer of resistance wire inside the leather of the steering wheel. The power supply line provides electricity to the resistance wire through the connection point below the steering wheel and the steering shaft, thereby generating heat.
