First, open the valve cover and rotate the piston. When one valve is depressed, it cannot be adjusted. Adjust the other intake valve so that the exhaust clearance on the opposite side exceeds 0.2 mm. Since the exhaust temperature is higher there and will cause expansion, set the clearance to 0.3 mm.

What is the fuel tank capacity of the Sagitar in liters?

The currently available Sagitar comes in 12 models, all with a fuel tank capacity of 50 liters. The vehicle is equipped with either a 1.4L turbocharged engine or a 1.2L turbocharged engine. The entire lineup features two transmission options: a 7-speed dry dual-clutch transmission (DCT) and a 5-speed manual transmission (MT). All models are front-wheel drive. Among vehicles in the same class, the 2021 Asian Lion has a fuel tank capacity of 50 liters, the 2022 Verano has a 44-liter tank, and the 2021 Bluebird also has a 50-liter tank. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the automaker is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level 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 calibrated tank capacity. To check the remaining fuel level, owners can observe the fuel gauge on the right side of the instrument panel, which is marked with E (Empty) and F (Full). When the needle is close to E, it indicates low fuel, while nearing F means the tank is nearly full.

Why is there no sound from Volkswagen Teramont's Bluetooth?

There are several main reasons why there is no sound from Volkswagen Teramont's Bluetooth: Sound is not turned on: When the car's multimedia system volume or the phone's volume is not turned on, there will be no sound when playing music via Bluetooth. While playing music, press the phone's volume button to adjust the phone's volume. Adjust the media volume to the maximum, then adjust the volume in the car. Incompatible pairing code: The music playback programming of some phones is incompatible with the pairing code of certain car models, so only phone calls can be made but music cannot be played. In this case, the Bluetooth playback frequency band needs to be changed. Media audio on the phone is not turned off: This can cause signal interference with the Bluetooth function, leading to no sound when playing music via Bluetooth in the car.

Where is the rearview mirror heating switch located on a BMW Mini?

The BMW Mini's rearview mirror heating button is a push-button type switch located on the control panel, featuring a square frame with three upward-curving arrows inside. Pressing this button activates the rearview mirror heating function. Principle of rearview mirror heating: Both side mirrors contain embedded heating elements (heating films). During rainy or snowy weather, when the driver activates the rearview mirror heating function, these heating elements rapidly warm up to a set temperature (typically between 35-60°C) within minutes, effectively defogging and defrosting the mirrors. The rearview mirror heating button icon should be distinguished from the front windshield defroster button: A fan-shaped symbol with three upward-curving arrows indicates the front windshield defroster, while a square frame with three upward-curving arrows represents the rearview mirror heating function.
