It is even permissible for all four wheel rims to have different styles. 2. Roof racks and side step boards can be installed: This new regulation mainly applies to SUV and MPV models. The height of the installed roof rack must be within 300 millimeters, and the width of the side step board must not exceed 5 centimeters beyond the side of the vehicle body. 3. Vehicle body color can be changed: The vehicle body color can be altered through painting or wrapping, but the changes must be registered with the vehicle management office within ten days. It is important to note that colors similar to those used on police cars, fire trucks, and other official vehicles are not allowed. 4. Grilles and front/rear bumpers can also be modified: The styles of grilles and front/rear bumpers can be changed. However, the installation of new grilles and bumpers must not alter the original length and width of the vehicle. The vehicle emblem cannot be changed, and the bumpers must not have any obvious protrusions, such as the so-called 'tow hooks' which are not allowed. 5. Roof racks no higher than 30cm can be installed: The new regulations state that passenger cars can install roof racks no higher than 30cm, provided that safety and stability are ensured.

Where to Check the Tire Pressure for Camry 2021?

The tire pressure for Camry 2021 can be checked on the dashboard, but you need to press and hold the tire pressure monitoring switch in the glove box first to view it on the dashboard. Tire pressure is crucial for tires; both too high and too low pressure will shorten the tire's lifespan. Low pressure increases tire deformation, leading to cracks on the sidewalls and causing flexing movements, which generate excessive heat and accelerate rubber aging. High pressure overextends the tire cords, reducing the tire's elasticity and increasing the load on the car while driving. This can cause internal cracks or blowouts upon impact. Additionally, high pressure accelerates tread wear and reduces puncture resistance. According to the international GBT2978-2008 standard, the recommended tire pressures are as follows: standard tires at 2.4-2.5 bar; reinforced tires at 2.8-2.9 bar; and the maximum pressure should not exceed 3.5 bar.

What does the SVS light on in JMC Transit mean?

SVS light on indicates that the engine control unit has detected an error signal from a sensor or that it has exceeded the usage standard. Below are the functions of the SVS indicator light and the reasons why the SVS light is on: Functions of the SVS indicator light: The SVS fault indicator light is a warning light that appears when the ECU or TCU of an electronically controlled fuel injection vehicle detects an issue with the engine or automatic transmission. For manual transmissions, it is the engine fault indicator light, while for automatic transmissions, it indicates both engine and automatic transmission faults. When the ignition key is turned on, this light will illuminate and should turn off after the vehicle starts. If the engine detects a fault, the SVS light will stay on. If this light comes on while driving, it indicates an engine fault. Reasons for the SVS light being on: Poor combustion state; low-quality fuel; dirty engine cylinders with carbon deposits. Solution: Use the recommended grade of gasoline for JMC Transit and clean the carbon deposits.

What is the fuel tank capacity of the Leopaard CS10?

The Leopaard CS10 has 7 models, all with a fuel tank capacity of 60 liters. The vehicle is equipped with either a 1.5T 150-horsepower engine or a 2.0T 177-horsepower engine, paired with a continuously variable transmission (CVT) or a six-speed wet dual-clutch transmission (DCT). Among vehicles in the same class, the 2019 Leopaard CS10 1.5T series and 2.0T series both have a fuel tank capacity of 60 liters. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity. To check the remaining fuel level, owners can observe the fuel gauge on the right side of the dashboard, marked with E and F. When the needle is close to E, it indicates low fuel, while nearing F means the tank is nearly full.

How many more years can a 2006 Passat be driven?

If the 2006 Passat is a non-commercial private vehicle, theoretically, as long as it passes the annual inspection and the mileage does not reach 600,000 kilometers, it can be driven indefinitely without any time limit. Introduction to Vehicle Lifespan: From the moment a car leaves the factory and begins operation, over long-term use, due to the aging and wear of components and other damages, the performance of the car gradually declines, and various consumptions increase, until it is no longer suitable for continued use, measured by continuous driving distance or continuous usage time. Lifespan Regulations: In industrially developed countries, the average lifespan of a car is between seven to twelve years. Based on the vehicle depreciation system previously implemented in China's transportation sector, it was stipulated that once a car reaches its depreciation period, it must undergo a technical assessment before being allowed to be scrapped. Due to the low depreciation rate, vehicles are not updated in a timely manner, leading to a higher proportion of old cars, which results in backward technical and economic indicators for enterprises and hinders the development of automotive technology.
