Pull up the key while simultaneously pressing open the clip. Remove the mechanical key and locate the gap in the electronic key to insert it. After inserting the key into the gap, gently pry it open. Open the back cover by tapping it on your palm to remove the battery. Finally, insert the new battery back in the same way.

How Long Can Tires with Cracks Still Be Used?

Tires with cracks can still be used temporarily for about a year, as the cracks are caused by natural rubber aging. Generally, small cracks will appear after 3 to 5 years of tire use. If the tires have been used for more than 5 years, they become harder, produce more noise, and essentially lose their rubber properties, so they should be replaced promptly. Relevant information about tubeless tires is as follows: Introduction: Tubeless tires, also known as "low-pressure tires" or "pneumatic tires," have high elasticity and wear resistance, along with excellent adhesion and heat dissipation performance. Especially, all-steel radial tubeless tires are economical and durable. Scope of Application: In recent years, tubeless tires have been increasingly used in bicycles, motorcycles, cars, buses, and trucks.

Will a Car Take in Water If It's Submerged?

If a car is submerged in water for half an hour, it will take in water. The water mainly enters through the throttle, windows, and trunk. Here's how to handle water ingress in a car: Turn off the engine: If the engine stalls due to water ingress during driving, immediately turn off the ignition and do not attempt to restart the engine. Move the vehicle to a safe location, preferably with the front higher than the rear, to allow water in the exhaust pipe to drain out and avoid damaging the catalytic converter and muffler. Remove the spark plugs: If it's determined that water has entered the engine, remove the spark plugs, manually cut off the fuel supply and ignition systems, and then crank the engine to expel the water. Also, check the fluid conditions in all vehicle systems; if foaming or cloudiness is observed, replace the fluids promptly.

What does EPA mean for cars?

EPA stands for the United States Environmental Protection Agency, which is the current standard for testing the driving range of vehicles in the United States. Constant-speed range refers to the maximum distance an electric vehicle can travel under the condition of maintaining a steady speed of 60 km/h. Relevant information about vehicle range is as follows: Introduction: Vehicle range refers to the farthest distance that can be traveled with the remaining fuel in the tank at a fuel-efficient speed, mainly calculated by the vehicle's computer based on current fuel consumption. Influencing factors: The vehicle's range is affected by four factors: charging equipment, tire pressure, whether the vehicle overtakes, and whether it frequently stops and starts abruptly.

What does the red exclamation mark on a car mean?

Red exclamation mark (specifically a circle with an exclamation mark inside), this represents a warning for the braking system, mainly indicating a brake system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark representing brake system faults, other exclamation marks on a car are yellow, indicating general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. This mainly includes parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant level below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating a fault in the car's lights. Solution: Go to a 4S shop for inspection and repair as soon as possible, or you can check it yourself. Focus on checking commonly used bulbs such as turn signals, fog lights, interior lighting, etc., to identify where the problem lies.

What Are the Symptoms of Excessive Carbon Buildup on Spark Plugs?

Symptoms of excessive carbon buildup on spark plugs: difficulty starting the car, low power, excessive exhaust emissions, increased fuel consumption. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure everything is cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires according to the firing order and secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replace spark plugs after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. You can refer to the following standards for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

Should a Broken Transmission Be Repaired or Replaced?

If the damage is not severe, it is recommended to repair it. Generally, the reason for replacing a transmission is either because it is beyond repair or the repair cost is too high. Whether a car's broken transmission should be repaired or replaced mainly depends on the extent of the damage and the cost of repair. Functions of a transmission: Changing the transmission ratio: To meet the traction needs under different driving conditions, allowing the engine to operate under optimal conditions and meet possible speed requirements. Enabling reverse driving: To meet the need for the car to move backward. The engine crankshaft generally only rotates in one direction, but the car sometimes needs to move backward, hence the reverse gear in the transmission is often used to achieve this. Interrupting power transmission: To stop power transmission to the drive wheels during engine startup, idle operation, gear shifting, or when parking is required for power output.
