Why are Infiniti cars less popular?

Due to low brand recognition, emissions not aligning with China's energy-saving and emission-reduction policies, and the historically tense Sino-Japanese relations leading to a significant boycott of Japanese products by many consumers. Infiniti Exterior: The Infiniti Q70L's exterior design continues the brand's signature styling. The front fascia delivers strong visual impact with its large grille and extensive chrome accents, creating a dynamic appearance. The headlight design serves as the focal point of the front end, with daytime running lights complementing the silver body when illuminated. Infiniti Interior: The Infiniti Q70L's interior design appears somewhat dated, as the model hasn't undergone a generational update for quite some time. The cabin layout remains overly complex, retaining numerous physical buttons that make it seem outdated compared to competitors like the Audi A6L and Mercedes-Benz E-Class. However, the interior excels in material quality, featuring abundant leather and wood trim that enhance its luxury appeal.

Should Snow on a Car Be Removed?

If a car is covered with accumulated snow, it is definitely necessary to clear the snow in a timely manner. Impact of Snow on Cars: Leaving snow uncleared will certainly obstruct the driver's view, as a snow-covered windshield makes it impossible to see the road ahead. Additionally, heavy snow on the car can cause windows, spray nozzles, and other parts to freeze, affecting their functionality. Moreover, snow actually contains corrosive substances such as alkaline, salts, or acids, which can damage the car's paint, causing the glossy finish to lose its shine. In areas with poor air quality, the damage could be even more severe. Therefore, snow on the car should be promptly cleared. Solutions for Snow on Cars: Pouring hot water directly onto the snow can cause the car windows to crack and the windshield wipers to deform due to the large temperature difference between hot and cold. It can also damage the car's paint. A better approach is to start the vehicle, turn on the heater, and direct the warm air toward the windshield. Wait for the snow to melt, then use a soft towel to remove it.

How to turn off the ESP in Volkswagen Polo?

Method to turn off the ESP in Volkswagen Polo: The ESP setting switch is located on the central control screen, marked with a "car skid prevention" icon. This function is enabled by default from the factory. Press the button to turn it off. The ESP can be temporarily turned off in the following situations: 1. When the vehicle is stuck in mud: ESP reduces some power output, which may result in insufficient torque for the vehicle to escape. 2. During extreme driving: Actions such as drifting around drainage channels or performing a launch start require appropriate slip rates, and ESP prevents the tires from slipping when active. 3. On deep snow-covered roads: The friction coefficient on snow-covered roads is low, and the tire friction resistance is already reduced. If the ESP continues to intervene, it may make it even harder for the wheels to escape. Note: On roads where the snow has just begun to melt, the ESP must be turned on, otherwise the vehicle may skid more severely. 4. When snow chains are installed on the tires: Changes in the tire's outer diameter may cause the sensors to misinterpret the tire's condition.
