Adjust the tire pressure to the standard value and perform the tire pressure system setup. The specific setup method is as follows: Turn on the ignition switch, press and hold the setting button for more than 2 seconds until the instrument panel emits a "ding" sound prompt. After confirming that the new parameters are stored, the warning light will turn off. The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving, alerting the driver to tire leaks and low pressure to ensure driving safety. There are two common types: direct and indirect. Below are the related introductions: 1. The direct tire pressure monitoring system has pressure sensors and transmitters installed on each wheel. If the tire pressure of any tire is 25% lower than the recommended cold tire pressure in the driver's manual, it will alert the driver. Its warning signal is more precise, and if a tire is punctured and the pressure drops rapidly, the direct system can provide an immediate warning. 2. The indirect tire pressure monitoring device is much cheaper than the direct system. It actually uses the speed sensors on the car's ABS braking system to compare the rotation counts of the four tires. If one tire has lower pressure, its rotation count will differ from the others. By using the same sensors and sensing signals as the ABS system, the onboard computer can establish a new function in the driving computer with software adjustments, warning the driver that one tire has lower pressure compared to the other three.

Does the Mercedes-Benz E300L have seat ventilation?

Mercedes-Benz E300L has seat ventilation. The control buttons are located at: 1. Front seats: The control buttons are located below the vehicle's center console, adjacent to the seat heating buttons. 2. Rear seats: The control buttons are located on the corresponding door panels, adjacent to the buttons controlling the electric seat adjustment, and arranged alongside the seat heating buttons. Information about seat ventilation is as follows: 1. Seat ventilation: It is the "summer cooling device" of the car seat air conditioning system. 2. Function: The unique ventilation circulation system of the seat ventilation continuously delivers fresh air through the small holes on the seat cushion and backrest, preventing sweat accumulation on the hips and back, providing a comfortable riding environment. It effectively improves the air circulation between the body and the seat surface, ensuring a dry and comfortable contact area even during long rides.

What does 102w tire mean?

102w tire means that 102 indicates the load index that the tire can withstand is 775kg; W indicates the maximum speed of the tire is 270km/h. The following is a related introduction about car tires: 1. Tire shelf life: The main component of tires is rubber, which has a shelf life, so tires also have a shelf life. Fresh rubber has the best performance, so newly produced tires also perform the best. ADAC's investigation of tires produced in different years but unused shows that the longer the tires are stored, the worse their performance becomes. 2. Replacement cycle: Tires are rubber products, and even if they are not used, they will age. It is recommended to replace tires every four years, and even if the mileage driven within the year is low, they should still be replaced once.

What Does Vehicle File Transfer Mean?

Vehicle file transfer refers to the process of extracting the vehicle's registration file from location A and bringing it to location B for re-registration. Detailed explanation of vehicle file transfer: When purchasing a used vehicle with an out-of-town license plate and intending to register it locally, a file transfer procedure is required. The transfer involves moving the vehicle's registration records. While ownership transfer simply changes the vehicle's owner, file transfer physically relocates the registration documents from the original jurisdiction to the new one. Important notes for vehicle file transfer: Required documents include: vehicle identification number rubbing, vehicle license, registration certificate, original purchase invoice or transfer invoice, valuation sheet, original ID cards or temporary IDs of both parties, transfer contract (for corporate entities: with attached copy of authorized person's ID), copies of documents (1 copy each of registration certificate, invoice, and original owner's ID; 2 copies of vehicle license; 3 copies of buyer's ID), power of attorney from both parties, and the 'Motor Vehicle Transfer Registration Form'.

What lights to use when driving straight through an intersection?

When driving straight through an intersection, learners should use low beam headlights; another scenario is when the voice prompt indicates passing through an intersection without traffic signal control, then you should alternately use high and low beam headlights twice. Turn signal usage scenarios: When turning, changing lanes, overtaking, making a U-turn, or pulling over to park, the turn signal should be activated 100 to 50 meters in advance. Low beam headlight usage scenarios: On roads without central isolation facilities or center lines, when meeting another vehicle at night, switch to low beam headlights when the oncoming vehicle is more than 150 meters away. Use low beam headlights when meeting non-motorized vehicles on narrow roads or bridges. High and low beam headlight usage scenarios: When driving through sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night, vehicles should alternately use high and low beam headlights.

How to View the Left Front Corner Inside the Car?

There is no unified or definitive method for viewing the left front corner inside the car; it mostly relies on the driver's own perception and habits. Here is supplementary information: 1. Judging the right front corner: When the vehicle is 20 centimeters away from an obstacle, the lowest point of the obstacle visible in the driver's line of sight is at a height of 80 centimeters. For sedans, 80 centimeters is approximately below the door handle. Therefore, when approaching an obstacle, ensure that you can see below the door handle or the lower edge of the headlight to avoid collision. 2. Judging the left-side distance: When the midpoint of the vehicle's left rearview mirror aligns with the left sideline, the distance between the vehicle and the sideline is approximately 1.5 meters. When the vertex of the angle between the left A-pillar and the lower edge of the windshield aligns with the left sideline, the vehicle is 60 centimeters away from the left sideline.
