What to Bring for the First Maintenance at a 4S Shop?

Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's registration certificate; vehicle's purchase invoice, to be taken to the designated first maintenance facility for the vehicle's initial service. 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. It is essential for the car to undergo its first maintenance on time, neither earlier nor later. Completing the first maintenance indicates that the car can be driven according to the standard load and normal speed as required. The timing for the first maintenance is calculated based on the date the car was picked up. There are two indicator values for the first maintenance: mileage and time. Whichever comes first will be the standard. First maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking various oil levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges, etc. Required time: Completing all tasks takes approximately 2 hours. The most crucial aspect of a new car's first maintenance is changing the engine oil and oil filter. When changing the engine oil, the oil filter must also be replaced simultaneously. The selection of engine oil must refer to the "Vehicle Usage and Maintenance Manual," as different models specify different engine oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people clean their cars themselves during holidays. Here, it is important to remind that the interior of the car body should not be directly washed with water. If the floor mats are dirty, a vacuum cleaner can be used, or they can be taken out, scrubbed with a brush and detergent, dried, and then placed back. There are many vent holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry naturally but will flow through the vent holes to areas like the gearbox, causing erosion and corrosion. A better approach is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the existing antifreeze and add the same brand of antifreeze from the start. Since antifreeze brands differ, their chemical properties vary significantly. Various functional additives may corrode those from other brands. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. To prevent rusting of bolts and nuts on the wheels, some people apply lubricant, which can introduce unnecessary risks to safe driving. At high speeds, bolts and nuts may loosen or even fall off, leading to driving failures.

What is the ESP system?

ESP, known in Chinese as the Electronic Stability Program, is an active safety feature in vehicles designed primarily to prevent skidding. It controls the braking of specific wheels when there is a significant difference in the speed of the four wheels. How ESP works: In cases of understeer, ESP will brake a specific rear wheel. For example, if there is understeer to the right, it will brake the right rear wheel, and if there is understeer to the left, it will brake the left rear wheel. Similarly, in cases of oversteer, ESP will brake a specific front wheel. Oversteer to the right will result in braking the left front wheel, while oversteer to the left will result in braking the right front wheel. On icy or snowy roads, if the vehicle starts to skid, ESP will also control the corresponding wheels to maintain stability. When to turn off ESP: When the vehicle is stuck in mud or during off-road driving: In situations where the vehicle is stuck or during other off-road conditions, some wheel slip is necessary to help the vehicle get unstuck or climb obstacles. Here, ESP's function of preventing wheel slip can be counterproductive. Therefore, during extreme off-roading or when stuck, it is advisable to turn off ESP to facilitate recovery. When encountering wheel slip while climbing in snow or rain: On snowy or wet roads, especially when going uphill, wheels are prone to slipping. The vehicle's computer may detect this slip and limit engine output, so it's best to turn off ESP before attempting to move. When using snow chains: Snow chains alter the wheel's outer diameter and can interfere with the data from certain sensors in the ESP system, leading to inaccurate signals. This can disrupt the normal functioning of ESP, possibly causing it to intervene constantly or trigger fault codes. In such cases, it is advisable to turn off ESP.

What does it mean when the car's set light stays on?

Set is the tire pressure monitoring light. If the vehicle's set light stays on, it indicates a tire pressure alarm, and the tire pressure needs to be stored. More information about the tire pressure monitoring light (Set) is as follows: 1. Tire pressure monitoring automatically checks the tire pressure in real time while the vehicle is in motion, alerting the driver to leaks or low pressure to ensure driving safety. 2. If the tire pressure system alarm is triggered, pull over and check the tire pressure of all four tires. If no obvious loss of pressure is visible, you can ignore it, reset the tire pressure system in the car, and continue driving once the warning light goes off. If the tire pressure warning light comes on again, it means there is an issue with one of the tires, and it should be inspected and repaired promptly. 3. If the tire pressure monitoring system warning light comes on while driving, reduce speed, avoid sharp steering and sudden braking, and check the tires immediately.

What to Do When the Car Navigation Screen Doesn't Light Up?

Navigation screen not lighting up can often be resolved by restarting the vehicle. If there is no change, it may indicate a hardware issue, and the vehicle should be taken to a 4S shop for repair or replacement as soon as possible. When purchasing a navigation system, pay attention to the following points: 1. Check and test the system's accuracy. Choose a familiar route to test whether the system can accurately display the vehicle's position. 2. System storage capacity. The car navigation system should have corresponding hard drive memory. 3. Image display. The image display of the car navigation system can be installed on the vehicle's dashboard, laptop, or handheld computer screen. The display screen should have good brightness, size, and resolution to adapt to different weather and lighting conditions.

What is the displacement of the N55 engine?

The displacement of the N55 engine is 3.0 liters, which is a 3.0-liter inline six-cylinder turbocharged engine with relatively strong power. Composition of the N55 engine: The N55 engine housing consists of the engine block, cylinder head, cylinder head cover, oil pan, and seals. The block is made of die-cast aluminum alloy, comprising the crankcase and base plate. Advantages of the N55 engine: The cylinder head of the N55 engine is a newly developed product. For the first time in a BMW six-cylinder engine, it features direct injection, an exhaust turbocharging system, and Valvetronic. The cylinder head has a compact structure and is equipped with the third-generation Valvetronic. The combination of the exhaust turbocharger, Valvetronic, and direct injection is referred to as Turbocharged Valvetronic Direct Injection, which reduces CO2 emissions or fuel consumption by 3-6 percentage points. Models equipped with the N55 engine: The N55 engine is used in various BMW models such as the 135i, 335i, 535i, 640i, 740i, and Z4. This engine has also been introduced into the domestic market and can be found in imported 335i and domestically produced 535i models in the current Chinese market.
