Does the Levin have an automatic locking function?

Levin has an automatic locking function, also known as speed-sensing auto-lock. It is an electronic device that automatically presses the lock button on the door when the vehicle reaches a preset speed to prevent accidental opening of the door. The lock automatically engages when the vehicle reaches a set speed, which is usually factory-set, typically between 10-20 km/h. Below is related information: Specific details: When the vehicle speed reaches the preset speed (usually set by the manufacturer, typically between 10 km/h to 20 km/h), the lock button is automatically pressed to prevent accidental door opening. This is the most common type of automatic locking method used in many car models. There are also other methods of automatic locking while driving. Additional information: For example, when the transmission is shifted into D (Drive) gear, the lock button is automatically pressed to prevent accidental door opening. Another method is when the driver steps on the brake while driving, the doors automatically lock. This method is usually found in domestic cars or some lower-end models. A less common locking method is when the vehicle has been continuously driven for 10 seconds, the doors automatically lock. Additionally, another common locking method is manual locking.

What is the fuel tank capacity of the 2013 Teana?

2013 Teana has a fuel tank capacity of 70 liters, which is the officially announced data. The 2013 Teana uses 92-octane gasoline with a fuel consumption of 7.3L per 100 kilometers. A full tank can run for approximately 958km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank. The fuel level is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is recommended to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is measured from the bottom of the tank to the safe limit. There is still some space from the safe limit to the tank opening, which is designed to allow the fuel to expand when the temperature rises without overflowing. If the fuel is filled up to the tank opening during refueling, the actual amount of fuel may exceed the marked tank capacity.
