On the Shanghai-Chongqing Expressway, the current speed limit standards are 100 km/h for passenger vehicles and 80 km/h for large vehicles. Below is relevant information about expressways: 1. Components: The expressway surface consists of several major parts including the main roadway, ramps, and auxiliary lanes. The main roadway refers to the traffic lanes, which are sequentially arranged from left to right as the overtaking lane, fast lane, and slow lane (travel lane) depending on their quantity. Ramps come in various complex forms, including entrance ramps, acceleration lanes, deceleration lanes, collector-distributor lanes, and turning ramps based on their specific functions. 2. Types: According to road scale, expressways are divided into three types: bidirectional four-lane, bidirectional six-lane, and bidirectional eight-lane.

Driving on the Hu-Yu Expressway, I often notice significant speed limit changes. Stretching over a thousand kilometers from Shanghai to Chongqing, the speed limit for cars is generally 120 km/h, but don’t assume it’s the same throughout. In mountainous sections like those in Hubei or Chongqing, where there are more curves and tunnels, the limit drops to 100 or even 80 km/h. I learned this the hard way—once, I wasn’t paying attention to navigation and slightly exceeded the limit, resulting in a ticket. Safety first—maintaining a steady speed on the highway also saves fuel. I use cruise control set around 110 km/h to avoid sudden acceleration. Always watch for roadside signs, as tunnel entrances usually indicate speed reductions. Remember, overtaking in tunnels is risky—don’t take the chance. In bad weather, especially heavy fog, slow down further. I recommend checking real-time traffic conditions before trips using navigation apps like Baidu Maps, which automatically alerts you to speed limit changes. Regularly check tire pressure to prevent blowouts that could affect driving.

Why is one side of the Mercedes headlight on?

Mercedes headlight on one side is caused by the turn signal switch not returning to its original position. Reasons for not returning: The "interference" between the return lever and the return disk is the key to the automatic return of the turn signal. That is to say, when the protrusions on the surface of the return lever or the return disk are severely worn, the return lever and the return disk cannot "interfere" with each other. As a result, the turn signal cannot automatically return to its original position when the steering wheel is straightened after the vehicle completes a turn. Solution: To solve this problem, it is necessary to remove the steering wheel and combination switch, check the wear degree of the return device, and selectively replace it according to the specific situation. Of course, besides malfunctions, sometimes the turn signal really cannot return automatically.

Where is the rearview mirror heating button located on the BMW X1?

The rearview mirror heating button on the BMW X1 is a push-button switch located on the control panel. It features a square frame with three upward-curving arrows inside. Pressing this button activates the rearview mirror heating function. Principle of rearview mirror heating: Both side mirrors are equipped with heating elements (electric heating films). In rainy or snowy weather, when the driver activates the rearview mirror heating function, these heating elements quickly warm up to a set temperature (typically between 35-60°C) within minutes, effectively defogging and defrosting the mirrors. The rearview mirror heating button icon should be distinguished from the front windshield defroster button: The front defroster button shows a fan shape with three upward-curving arrows, while the rearview mirror heating button displays a square frame with three upward-curving arrows.

What is the normal gasoline pressure for the BMW 760 N73 engine?

BMW 760 N73 engine gasoline pressure normal value is between 300 to 350 kPa. Fuel pressure gauge: The fuel pressure gauge is used to measure the pressure of the fuel supply system, determine the working condition of fuel system components such as the electric fuel pump and fuel pressure regulator, and is a specialized tool for inspecting and diagnosing faults in the fuel system. Usage method: Start the engine and run it until it reaches normal operating temperature; turn off the car and wait for the engine to stop running, then remove all spark plugs; fully open the throttle, press the pressure gauge connector tightly onto the spark plug hole; use the starter to rotate the engine at 100 to 150 rpm for 3 to 5 seconds; the pointer on the gauge will gradually rise until it stops at a certain value, which is the fuel pressure of the engine.

What is the coding for the Lavida airbag control unit?

Lavida airbag control unit coding is 12344. Working principle of airbags and airbag warning light: Airbags are generally composed of sensors, microprocessors, electronic control units, airbag covers and support rings, airbags, airbag modules, etc. The illumination of the airbag warning light may be caused by a malfunction in one of these components. Reasons for airbag warning light illumination: The reason for the airbag warning light illumination may also be a false fault phenomenon. If the car battery is low or other electrical equipment in the car is damaged, it may affect the feedback voltage of the airbag, resulting in a fault code.

What causes the malfunction of the rear door lock on the Encore?

The malfunction of the rear door lock on the Encore may be due to a damaged motor in the rear door. Damaged motor: If the motor is damaged, it needs to be replaced. Automatic door closing: Insufficient lubrication of the door lock mechanism: When the door lock becomes stiff or tight, some people tend to drip a few drops of lubricating oil into the lock cylinder. However, this can create a greasy residue, making the lock more prone to malfunction. The correct method is to shave some pencil lead shavings (or candle shavings) and blow them into the lock cylinder. Weak central control motor in the door: The insufficient power of the central control motor in the door may be caused by long-term wear and aging. It is recommended to replace the motor with a new one.
