What to Pay Attention to When You Just Picked Up a New Car?

What is the battery model for Mercedes-Benz keys?

The battery models are CR2032, CR2025, etc. These are lithium manganese dioxide batteries, named according to the IEC standard. Among them: C- indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R- indicates that the battery shape is cylindrical, if it is square, F is used instead; 20 indicates the battery diameter is 20mm; 32 represents the battery height is 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity is around 200mAh. CR2032 typically has a lifespan of 5 years. If the manufacturer's production level is not high or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture interference, etc.), the lifespan can be further extended to 8 years or even 10 years. The usage time of a vehicle remote key battery is closely related to the frequency of use. The more frequently it is used, the shorter the lifespan will be. If the remote key battery runs out, the mechanical key can be used directly to open the vehicle and start the engine. Car remote keys use button batteries, mainly three types: CR2016, CR2025, and CR2032. For the specific model used in each vehicle, owners can refer to the battery model in the user manual for replacement. Button-type CR2016 battery: This is one of the most commonly used car remote batteries. The battery voltage is 3V. Most car key batteries are powered by 9V, so all three batteries need to be replaced each time. Examples include Guangben, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter 20mm, thickness 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than CR2016, but it is still used in some car keys. It is thicker than CR2016 but has a relatively higher storage capacity. CR2025 specifications: battery diameter 20mm, thickness 2.5mm. This type of battery is also commonly used in audio remotes. Button battery CR2032: Its thickness is twice that of CR2016. The 3V-CR2032 lithium manganese battery belongs to the lithium-manganese dioxide structure. The positive electrode material is chemically stable manganese dioxide, the negative electrode material is lithium metal, and the electrolyte is a lithium battery electrolyte. The main components of the electrolyte are dimethoxyethane, propylene carbonate, and lithium perchlorate. It is shaped like a button, hence the name button lithium battery or lithium manganese button battery. Button battery CR2450: Compared to the other three, it is thicker and larger, with a diameter of 24.5mm and a height of 5.0mm. The rated current value of CR2450 is 0.2mA, mainly used in low-power electronic products. Generally, such batteries can provide an output current of 0.001mA to 5mA, with a continuous output current of up to 15mA and a flash output current of up to 30mA, meeting the requirements of most small electronic products for light emission, sound, and RF output.

Where to Replace a Driver's License with Full Stamps?

When the stamps on your driver's license are full, you need to apply for a replacement at the vehicle management office. Here are the details regarding driver's license stamping: 1. Generally, after an annual inspection, a new inspection validity period stamp needs to be added to the supplementary page of the driver's license. 2. When the validity period stamps on the supplementary page are full, you need to replace the supplementary page before the next annual inspection. The documents required for replacing the supplementary page of the driver's license include: 1. ID card and driver's license: These are needed to fill out the application form at the vehicle management office. 2. ID card, driver's license, and compulsory traffic insurance policy: These are required to obtain the annual inspection form at the motor vehicle inspection agency. 3. Annual inspection form, driver's license, inspection results form, and vehicle inspection certificate: These are needed to obtain the motor vehicle inspection compliance mark at the vehicle management office and to stamp a new inspection validity date on the supplementary page of the driver's license.

What Could Be the Reason for Suddenly Unable to Accelerate While Driving Normally?

If a vehicle suddenly cannot accelerate while driving normally, it may be caused by excessive carbon deposits. Due to carbon buildup, localized high temperatures can cause the combustible mixture to ignite prematurely before being sparked by the spark plug, a phenomenon commonly known as detonation. This disrupts the engine's normal operation, resulting not only in vibrations but also in a lack of power when pressing the accelerator, making the drive very jerky. Here are some solutions: 1. Check the fuel tank pump to see if it is functioning properly. The fuel pump motor should make a sound when operating. If the fuel pump cannot supply fuel normally, it will lead to insufficient vehicle power. 2. Inspect the fuel filter to ensure it is working well and check for any fuel leaks or blockages. If the fuel leak is severe, starting the vehicle could potentially ignite it due to static electricity. 3. Examine the intake pipe for any dirt blockages. Remove the air filter to check if it has been exposed to water. Replace the air filter if necessary. 4. Verify if the valve timing is correct and whether the intake and exhaust pipes are tightly sealed. You can clean the throttle body or add a cleaning-type fuel additive (fuel system cleaner) to the fuel, which can help remove carbon deposits to some extent.

What does coast/set mean?

coast/set refers to some switches in the cruise control system. SET/COAST button – speed setting/deceleration control switch (allowed when speed is greater than 30Km/H). When pressed while driving, it sets the current speed, and the CRUISE cruise setting indicator light on the water temperature gauge illuminates. After releasing the accelerator, the car will drive at the set speed. During cruise control, pressing the SET/COAST button again will reduce the speed by 1.6Km/H each time. Below is an introduction to the cruise control function buttons: 1. ON/OFF button – cruise control switch. When the ON/OFF button is pressed, the CRUISE/MAIN cruise main indicator light on the water temperature gauge illuminates. The cruise control system is activated and ready to accept various speed control operations. Pressing the ON/OFF button again turns off the CRUISE/MAIN cruise main indicator light and closes the cruise control system. 2. RES/ACCEL button – acceleration setting/acceleration control switch (allowed when speed is greater than 30Km/H) (1) During cruise control, pressing the RES/ACCEL button increases the speed by 1.6Km/H each time. (2) Holding it down will continuously increase the speed. (3) Pressing the CANCEL button will temporarily stop the cruise control, and pressing the RES/ACCEL button again will cause the car to accelerate rapidly to the previous cruise speed.

How to Remove the Headlights of the New Fit?

You should locate a cover behind the headlight, twist it open to reveal the bulb, and then unscrew the bulb from its mounting clip with your fingers to successfully remove the headlight. Car headlights, also known as LED daytime running lights, are not only related to the appearance of the vehicle but also closely linked to safe driving at night or under adverse weather conditions. Below are the precautions for removing the headlights of the new Fit: 1. Wear gloves throughout the entire replacement process; after removing the bulb, avoid touching the glass of the bulb directly with your hands. 2. It is not necessary to choose the original bulb brand when purchasing; as long as it meets the national 3C certification standards, it can be used. 3. Before starting the replacement, ensure the vehicle is turned off, the key is removed, and wait for the engine to cool down completely. 4. Make sure the voltage and wattage of the bulb are the same as the original car's. Do not believe merchants who claim that increasing wattage will increase brightness, as this can cause unstable current and lead to short circuits. The method for removing the headlight bulb of the new Fit is as follows: First, turn off the vehicle for more than 5 minutes, remove the key, and wait for the engine to cool down completely. Then, open the engine compartment cover to avoid burning any parts.

What are the reasons for restricted engine power?

There are several reasons for restricted engine power: 1. Carbon deposits in the cylinders, throttle valve, spark plugs, or intake system. These areas are directly related to the engine's power output. Excessive carbon buildup inside the engine can reduce ignition energy and intake efficiency, ultimately leading to decreased engine power and weak idling. 2. Using incompatible fuel grades (e.g., using 90 octane instead of 93 octane), which reduces the vehicle's output power and performance. Alternatively, blockages in the fuel tank vent hole, fuel tank switch, fuel filter, or fuel lines between the tank and carburetor can restrict fuel supply, resulting in a lean air-fuel mixture and poor engine acceleration. 3. Air is one of the engine's power sources. If the air filter is clogged due to prolonged use without cleaning, insufficient air intake will cause an overly rich air-fuel mixture, reducing engine power. For vehicles with turbochargers, failure of the turbocharging system can also lead to decreased engine power or performance. 4. Insufficient engine oil, low coolant levels, or malfunctioning engine cooling systems can increase the engine's load and cause poor heat dissipation. Engine overheating leads to inadequate lubrication, increased mechanical wear, reduced engine power, and higher fuel consumption.
