The reason for no response when plugging into the USB port in the LaCrosse armrest box is that the connection between the USB port and the motherboard is broken. The USB port is a type of vehicle transmission line, known for its fast transmission speed and flexible connection, serving as a universal interface for USB devices such as flash drives and MP3 players. Taking the 2021 LaCrosse as an example, it belongs to the mid-size car category, with body dimensions of: length 5026mm, width 1866mm, height 1459mm, and a wheelbase of 2905mm. The 2021 LaCrosse is equipped with a 1.5L turbocharged engine, delivering a maximum horsepower of 169PS, maximum power of 124kW, maximum torque of 250Nm, and is paired with a 9-speed automatic transmission.

What torque is needed to tighten wheel bolts?

Typically, the torque for wheel bolts on passenger cars is around 100-120 Newton meters. Below is an explanation of the required torque for tightening wheel bolts: 1. Principle: There is a specific sequence for tightening wheel bolts. They should be tightened in a crisscross pattern in three stages to ensure even force distribution and secure installation. It's important to note that overtightening the bolts is not ideal, as it can stretch the threads or even cause cracks. 2. Required torque: The torque varies depending on the vehicle model. Always refer to the manufacturer's manual for the specified torque value (in N·m). Some vehicles use bolts instead of nuts, which generally require less torque because bolts have tapered seats. Over-tightening can lead to wheel damage.
