The reasons why the car does not respond when the key is pressed are: 1. The remote key battery is dead or the car battery is dead; 2. There is a strong signal interference source nearby, and you can use the mechanical key hidden inside the remote key to open the car door. If even the mechanical key cannot open the car door, it may be that the car's central locking system is in an electronic locked state. You need to wait for one or two hours for the lock to be released before attempting to unlock it again. A remote key refers to a key that can open and lock the door from a distance without inserting the key into the keyhole. It emits a weak radio wave from the owner, which is received by the car antenna. The electronic control unit (ECU) identifies the signal code, and then the system's actuator (motor or electromagnetic coil) performs the action of opening or closing the lock. This system mainly consists of two parts: the transmitter and the receiver.

How to Identify the Date on Car Glass?

The method to check the date on car glass is as follows: The glass is marked with numbers and black dots indicating the production year and month. The number represents the year, which can be determined based on the vehicle's manufacturing date. The black dots represent the month; if the dots are in front of the number, subtract the number of dots from 7, and if they are behind the number, subtract from 13 to get the month. Some glass may also have a few thick black dots after the production year and month, which are used to specify the week of the month. Relevant information about car glass includes: 1. Introduction: Car glass is an essential part of the vehicle's body accessories, primarily serving a protective function. 2. Classification: Car glass mainly falls into three categories: laminated glass, tempered glass, and zone-tempered glass, which can withstand strong impacts. Car glass is also categorized by its location: front windshield, side window glass, rear windshield, and sunroof glass.

What is the fuel tank capacity of the classic Cruze in liters?

The fuel tank capacity is 54 liters. Here is some additional information: 1. The fuel tank capacity indicated in the car's factory manual refers to the "standard fuel tank capacity." 2. According to relevant national standards, the nominal capacity of a car's fuel tank cannot exceed 95% of its actual capacity. The manual can indicate a smaller capacity but not a larger one, so the actual capacity of the fuel tank is generally greater than the standard capacity. 3. The actual capacity of the fuel tank is larger than the nominal capacity. Based on fuel safety characteristics, national regulations stipulate that the nominal capacity of a car's fuel tank is 95% of its rated capacity. Therefore, when filling up, you can add up to 10% more fuel than the nominal capacity. 4. Gasoline is a volatile liquid and operates at high temperatures, which means it has an expansion coefficient. If no expansion space is left for the gasoline, overflow can occur when the tank is full, leading to safety hazards.

What is the purpose of the black line on the left rearview mirror of an Audi?

The black line on the left rearview mirror of an Audi serves to identify distance and position. Significance of the black line: The inner side of the black line provides a normal field of view for observing nearby conditions. Due to its larger curvature, it allows for a clear view of nearby situations, such as seeing the position of the rear wheels and adjacent vehicles when reversing. The outer side of the black line expands the driver's field of vision. During regular use, the Audi's rearview mirror combines two different curvatures to balance both near and far views, effectively reducing blind spots and enhancing convenience, thereby lowering potential hazards. Design principle of the Audi left rearview mirror: The black dotted line acts as a divider, with the right side being a flat mirror and the left side a convex mirror. This design doubles the field of vision while maintaining minimal distortion and virtually eliminates blind spots during turns, enabling the driver to see a panoramic view behind the vehicle.

Which brand of tires does the Honda Fit hatchback come with as original equipment?

Honda Fit hatchback comes with Dunlop ENASAVE-EC300 tires as original equipment. Below is relevant information about Honda Fit tires: 1. Overview: The ENASAVE-EC300+ is part of Dunlop's fuel-saving and eco-friendly ENASAVE series. The Dunlop ENASAVE-EC300 tires equipped on the Honda Fit have a maximum load capacity of 615kg per tire and a maximum air pressure of 350Kpa. The 615kg maximum load capacity is equivalent to the combined weight of eight 80kg adults. 2. Notes: The replacement cycle for passenger car tires is generally around 2-3 years or 60,000-100,000 kilometers. Of course, the specified service life may vary between different brands, as their requirements for tires differ slightly. However, relying solely on a numerical value to determine replacement time is insufficient; the actual condition of the tires should be the deciding factor. Since everyone's driving environment varies, there may be cases of premature or delayed wear.

What causes a car to fail to start after passing through a water puddle?

Car failing to start after passing through a water puddle is due to water entering the engine. After driving through water, never attempt to restart the engine. Immediately call for a tow truck and have the vehicle inspected at a repair shop. Starting the engine when water has entered can cause severe engine damage, and such damage is typically not covered by insurance. Effects of water exposure on a car: 1. Cars have numerous cavities that are extremely difficult to clean once water enters, leading to mold and rust over time. Examples include the inner door panels, air conditioning ducts, and structural cavities. Areas like the crankcase and differential also have vent holes. 2. Upholstery and soft furnishings soaked in dirty water: These can leave stubborn stains and, if not properly dried, may continue to grow mold. 3. Components like the four-wheel bearings and axle grease: Water exposure can quickly degrade their quality. 4. Electronic devices in the car: Systems such as the electronic parking brake, audio system, and various sensors can develop persistent issues if not repaired promptly after water exposure.
