What Needs to Be Done for the First Maintenance of a New Car?

The first maintenance at a 4S shop includes the following aspects: changing the engine oil and oil filter, cleaning the air filter; checking whether the levels of various fluids are normal, inspecting the generator belt and wiper blades for any damage; checking whether the tire pressure is normal, and whether the tires have uneven wear, bulges, or damage; inspecting the chassis, including the brake pads, brake discs, connecting rods, ball joints, CV joints, and any scratches; checking all the switches in the car; and ensuring the lights are functioning properly. Estimated time: Completing all tasks takes about 2 hours. Items to bring for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; and the vehicle purchase invoice. Take the car to the designated first maintenance facility for service. Important note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after driving a new car, and the specific timing varies by vehicle, typically after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance on time—neither early nor delayed. Completing the first maintenance indicates that the car's break-in period has ended, and it can now be driven under standard load and normal speed as required by the vehicle. The first maintenance period is calculated from the date of vehicle pickup. There are two indicators for the first maintenance: mileage and time. Whichever comes first serves as the standard. The following inspections and replacements must be completed during the first maintenance of a new car: changing the engine oil and cleaning the three filters (oil filter, fuel filter, and air filter); checking whether the coolant level is normal; inspecting the car's brakes and the fluid level of the clutch; checking the power steering fluid level and whether there are any oil leaks at the pipe connections; inspecting the condition of the generator, air conditioning, water pump, and belts for aging and tension; and examining tire pressure and wear, inflating the tires if necessary, or rotating them if there is uneven wear. When changing the engine oil, the oil filter must also be replaced. The choice of engine oil must refer to the Vehicle User Maintenance Manual, as different models require different oil specifications. Maintenance precautions: Do not rinse the interior of the car with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior should not be directly rinsed with water. If the floor mats are dirty, use a vacuum cleaner or remove them, scrub with a brush and detergent, dry them, and then put them back. The rubber mats under the driver's floor have many drainage holes. If water enters, it will not dry naturally but will flow through the holes to areas like the gearbox, causing corrosion. The best practice is to clean with a vacuum and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: If the antifreeze level is low, it is recommended to drain the existing antifreeze and refill it with the same brand. Different brands of antifreeze have varying chemical properties, and mixing them can lead to corrosion. Each brand uses different corrosion inhibitors, so avoid mixing them to prevent unnecessary issues. Do not lubricate wheel bolts and nuts: If the bolts on a car become rusty, some people oil them to make them functional again. However, applying lubricant to wheel bolts and nuts can pose safety risks. At high speeds, the bolts and nuts may loosen or even fall off, leading to driving hazards. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: The starter of an EFI car differs from that of a conventional car. Its fuel injection control system can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.

What is the reason for the cabin dome light not working?

If there are no issues with the car's electrical wiring, it might be due to incorrect button settings. Generally, there is a button near the dome light in the cabin, which offers three modes: ON (constant light mode), DOOR (light turns on when the door opens and off when it closes), and OFF (light off mode). It is usually set to DOOR mode, where the light automatically turns on when the door is opened and off when it is closed. Here is a detailed explanation: 1. Constant light mode, where the light stays on (ON); 2. Constant off mode, where the light remains off (OFF); 3. Automatic light mode, where the light turns on when the door opens and delays turning off after the door is closed (DOOR).

Will there be any problem if water enters the intake without stalling?

Generally speaking, if a car passes through water without stalling, there should be no problem. Here is some related information about stalling: 1. Reasons for stalling: Automatic transmission models: Vehicles with automatic transmission are less likely to stall, while manual transmission models may stall frequently due to lower driving skills. However, it is not impossible for automatic transmission cars to stall, mainly due to the use of low-quality fuel causing engine carbon buildup and stalling. 2. Precautions: For automatic transmission cars stalling, the main cause is the use of low-quality fuel. One solution is to refuel at reputable, larger gas stations with higher-grade fuel, such as using 97-octane gasoline. Although it is more expensive, it can ensure a longer lifespan for your car and better performance while driving.

What does a used car dealer mean by 'premium condition'?

The term refers to vehicles with low mileage, no history of accidents, fire damage, or flooding, and no repainting on the exterior. Here are some considerations when buying a used car: 1. Pay attention to the exterior: Some used cars have been in accidents. To increase their value, dealers may refurbish them, including repainting, to make them look newer. Therefore, when purchasing, carefully inspect the exterior, check all corners and parts for signs of repainting, and look for wear on the tires, headlights, and bumpers. 2. Check the chassis and frame: After an accident, even if the exterior is well repaired, the frame and chassis are difficult to restore. If you notice any deformation or bending, be cautious—it might be an accident-damaged car.

Do I need to go to the vehicle management office in person to change to a C2 license?

Changing to a C2 license requires the applicant to go to the vehicle management office in person. Below are the relevant details about modifying the driver's license record: 1. Relevant regulations: For cases where the applicant requests a correction, the acceptance officer verifies the items to be corrected and fills out the Motor Vehicle Driver's License Correction Form; for cases where the file management officer requests a correction, the file management officer fills out the Motor Vehicle Driver's License Correction Form. The acceptance officer enters the correction information. If a new motor vehicle driver's license needs to be issued, it will be produced and issued, and the original motor vehicle driver's license will be collected. 2. Documentation: The file management officer checks the computer management system information, reviews, and retains the original Motor Vehicle Driver's License Correction Form.

How often should the shift cable be replaced?

The shift cable should be replaced only when it is broken, as there is no fixed time limit. A faulty shift cable can affect normal gear shifting. Before the shift cable breaks, you may experience difficulty when pressing the clutch, difficulty engaging gears, or incomplete gear engagement. If the shift cable head detaches from the gear head or the clutch cable breaks, it will result in the inability to shift gears. Below is more detailed information: 1. Transmission structure and principle: The function of the transmission is to change the gear ratio to meet the traction needs under different driving conditions, allowing the engine to operate under favorable conditions and meet possible speed requirements. It also enables reverse driving to meet the need for backing up. 2. Shift cable: This is the cable connecting the lower part of the gear lever to the transmission when shifting forward or backward. The shift position cable is the one connecting the lower part of the gear lever to the transmission when moving the lever left or right.
