The 'set-' on a car refers to cruise control deceleration, or alternatively, temporarily canceling the cruise control. Pressing 'set' sets the current speed as the cruising speed, and the corresponding button to 'set' is 'res'. The 'res' button also has two meanings: one is to accelerate after setting the cruise control, and the other is to restore the previously set speed after temporarily canceling the cruise control by pressing 'res'. The function of 'set' is that after adjusting the tire pressure of all four tires to the standard pressure, long-press 'set' for three seconds while observing the speedometer; a symbol with an exclamation mark inside brackets will appear. Upon hearing a 'ding' sound, the tire pressure of all four tires will be calibrated according to the adjustments made.

How often should the carbon canister in a sedan be replaced?

The carbon canister in a sedan is not a wear-and-tear part and does not have a fixed replacement interval. If the car exhibits symptoms such as jerking, increased fuel consumption, or a gasoline smell, and troubleshooting proves ineffective, it is necessary to check whether the carbon canister needs replacement. When gasoline in the fuel tank produces vapor, releasing it directly into the air would cause environmental pollution. Therefore, the carbon canister stores these vapors and introduces them into the engine cylinders for combustion under appropriate operating conditions. The carbon canister is typically installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank often contains vapor at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from evaporating into the atmosphere.

What is the working principle of the Cruze power steering pump?

The working principle of the Cruze power steering pump is: when the car is turning, the torque sensor detects the torque of the steering wheel and the intended direction of rotation. These signals are sent to the electronic control unit via the data bus. The electronic control unit then issues action commands to the motor controller based on the transmitted torque, intended direction, and other data signals. As a result, the motor outputs the corresponding amount of rotational torque as needed, thereby generating power steering. The Cruze is a compact car under SAIC-GM Chevrolet, with dimensions of 4666mm in length, 1807mm in width, and 1460mm in height, and a wheelbase of 2700mm. The car offers six body colors: Aurora White, Obsidian Black, Cold Platinum Silver, Glacier Blue, Titanium Gray, and Flame Red.
