The first maintenance at a 4S shop includes the following aspects: changing the engine oil and oil filter, cleaning the air filter; checking the levels of various fluids to ensure they are normal, inspecting the generator belt and wiper blades for any damage; checking tire pressure for normalcy and examining tires for uneven wear, bulges, or damage; inspecting the chassis, including brake pads, brake discs, connecting rods, ball joints, CV joints, and any scratches; checking all switches in the vehicle; ensuring all lights are functioning properly. Estimated time: Completing all tasks takes approximately 2 hours. Items needed for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle purchase invoice. The first maintenance should be performed at the designated service center. Important note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven. The specific timing varies by vehicle, generally after driving 1,000 to 3,000 kilometers. It is crucial to attend the first maintenance on time, neither earlier nor later. Completing the first maintenance marks the end of the car's break-in period, allowing it to 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 will be the standard. Here are the essential inspections and replacements that 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 the coolant level to ensure it is normal; inspecting the brake fluid and clutch fluid levels; verifying the power steering fluid level and checking for any leaks at the oil pipe connections; examining the generator, air conditioning, water pump, and belts for aging and tension; checking tire pressure and wear condition, inflating tires as needed, or performing tire rotation if wear is detected. 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 vehicle models require different oil specifications. Maintenance precautions: Do not rinse the interior of the car with water: Many people clean their cars during holidays, using water to wash the body and wiping it with a cloth. It is important to note that the interior should not be directly washed 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. Water entering these areas will not dry naturally but may flow through the holes to corrode components like the gearbox. The best practice is to use a vacuum cleaner for cleaning, followed by wiping 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 may cause corrosion. Always use the same brand to avoid unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a car rust, some people apply oil to make them functional again. However, lubricating wheel bolts and nuts can pose safety risks. At high speeds, lubricated 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: EFI cars differ from conventional vehicles. Their fuel injection control system can automatically adjust the fuel supply based on the engine's temperature and operating conditions, ensuring a smooth start.
