How to Check the Engine Oil Level in a BMW 3 Series?

To check the engine oil level in a BMW 3 Series, follow these steps: Adjust using the control button above the turn signal in the vehicle information display. Insufficient engine oil will increase friction between engine components, leading to decreased engine performance. Excessive oil will increase the rotational resistance of the crankshaft, causing higher oil consumption, blue smoke emission, and accelerated wear of cylinders and pistons, ultimately shortening the vehicle's lifespan. The BMW 3 Series is a sedan model under the BMW Group, with dimensions of 4734mm in length, 1811mm in width, and 1455mm in height, and a wheelbase of 2920mm. The vehicle features a polygonal double-kidney grille and new Angel Eye headlights, with an additional groove in the middle below the headlights. The bumper lines extend into the groove to connect with the headlights, presenting a smooth and rounded overall design.

What are the advantages and disadvantages of the auto-hold function?

The advantages of the auto-hold function are: 1. It prevents the vehicle from rolling when encountering short stops such as traffic lights; 2. When starting on an uphill slope, the system automatically brakes to prevent rolling back, and releases the wheels to move forward once the vehicle starts; 3. There is no need to pull the handbrake when parking and locking the car, as the system automatically brakes the wheels, but this feature is only available in some models. The disadvantage of the auto-hold function is: Poor throttle control during reversing may lead to accidents. The auto-hold function is an extension of the Electronic Stability Program (ESP) and controls the four-wheel braking through ESP. During this process, the ECU computer uses sensors installed on the vehicle to detect the vehicle's level and wheel torque, determining whether braking is needed to prevent rolling. The braking force applied to the wheels is not excessive, just enough to stop the vehicle from moving, ensuring there is no severe lurch forward when the accelerator is pressed again.

Can National V Vehicles Be Transferred?

National V vehicles can be transferred. After the implementation of the National VI emission standards, there is no impact on the transfer of second-hand National V vehicles within the same locality. This means that in regions where the National VI emission standards have already been implemented, second-hand vehicles that do not meet the National VI standards can still be transferred normally. Below are the differences between National VI and National V standards: Different Emission Standards: The National VI standards are stricter than National V. In terms of emission standards, nitrogen oxides are reduced by 77%, particulate matter by 67%, and the introduction of particle number limits imposes more stringent requirements. National VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. During the National V phase, the emission standards for diesel and gasoline vehicles were different. Different Vehicle Prices: National VI vehicles are significantly more expensive than National V vehicles. Different Supervision and Management: National VI introduces stricter compliance supervision and management requirements, including type inspection and information disclosure, production consistency inspection, and new vehicle inspection, while simplifying the method for determining standard compliance.

What to Do When the Car Trunk is Frozen and Won't Open?

Use a hairdryer to blow warm air for about ten minutes, or park the car under the sun for approximately an hour. Below are methods to open the trunk: Remote Key Control (Outside the Car): Press the trunk release button on the car key directly. Some models may not have a dedicated trunk button on the remote key, in which case pressing the unlock button will also release the trunk. Control Switch Inside the Car: Opening the trunk from inside the car is also possible. Most car models on the market are equipped with a trunk release button. The location of this button varies depending on the manufacturer and model, typically found on the left side of the steering wheel or in the central control area. Some models may not have a button but a lever instead. These levers are usually located on the lower left side of the driver's seat or the steering wheel, marked with an icon of a car trunk lifting up.

How Often Should You Wax Your Car?

Car waxing should be done every 3 to 4 months, depending on actual usage conditions. Below are guidelines on waxing frequency and precautions for new cars: Frequency of car waxing: Theoretically, the interval between car waxing depends on how long the wax layer lasts on the paint surface, which in turn is determined by the quality of the wax used. Waxing should not be done too frequently. Precautions for waxing new cars: New cars come with excellent paint surface conditions. Waxing can effectively protect the paint from oxidation caused by UV rays and maintain its shine. However, avoid unnecessary waxing.
