A steering wheel with an exclamation mark is the electronic power steering fault warning light. The steering wheel icon on the car dashboard refers to the power steering system. When this light illuminates accompanied by an exclamation mark, it indicates an issue with the vehicle's power steering system. The steering system is a series of devices designed to change or maintain the vehicle's direction of travel or reverse, functioning to control the car's direction according to the driver's intention. The working principle of automotive power steering systems is: after the drive wheel rotates the rotor, the vanes expand under centrifugal force and form working chambers together with the stator, rotor, and oil distribution plate. This directs high-pressure oil discharged from the pressure plate through the steering oil pipe into the steering gear to provide power assistance.

How to Deal with ETC Device Malfunctions?

Methods for handling ETC device malfunctions: 1. Check if the ETC device has power. Remove the ETC card and reinsert it into the device. If the ETC device does not emit a beep sound, it can be confirmed that the device is out of power. Simply drive the car to a sunny area to recharge it. 2. If the ETC device displays an "invalid tag" message, it means the electronic tag attached to the car's front windshield has fallen off. In this case, you need to visit an ETC card service point for reactivation. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a road toll method specifically designed for toll roads, commonly found on highways, toll bridges or tunnels, and certain sections of urban roads, aimed at alleviating urban traffic congestion.

What to Do When the External Tire Pressure Monitor Cannot Be Removed?

Solutions for removing an external tire pressure monitor: Apply a few drops of lubricating oil at the nut, wait for an hour, then use the original nut to unscrew it or use small needle-nose pliers to twist it off. The external tire pressure monitor uses a pin to push open the valve core, and the air pressure impact received by the sensor is the internal tire pressure. The sensor cleverly utilizes the thread that secures the dust cap to fix it onto the valve stem. Tire pressure monitors can be categorized into built-in and external types based on the installation position of the sensor module. Both external and built-in types are manifestations of direct tire pressure monitoring systems. There are differences in product positioning between built-in and external types, but there is no functional superiority or inferiority between them.

Do I Need to Replace the Rims When Changing Tires?

Replacing tires does not require replacing the rims. As long as the rims are undamaged, you only need to replace the tires with the same size and specifications as the original factory tires during a tire change. There is no need to replace the rims as well. Tires, as components that directly contact the ground to bear the vehicle's weight and provide the necessary friction for driving, operate under extremely harsh conditions. They not only endure exposure to sun and rain but also withstand extreme cold in winter and high temperatures in summer. When replacing tires, it is crucial to ensure that the new tires match the original factory tire size and specifications, and that all four tires on the vehicle are of the same size and specifications. Using tires that do not meet the required specifications can significantly impact the vehicle's driving quality and even pose serious safety risks, creating major safety hazards.

What is the method of pressing the clutch before braking?

The method of pressing the clutch before braking: If you encounter a red light at an intersection and need to stop, or when pulling over to the side, you should first press the clutch. When approaching the crosswalk, directly apply the brakes. This is because the lower the car's speed, the greater the frictional resistance between the tires and the ground. If you brake first, the engine is more likely to stall. The minimum speed for each gear is the speed when the engine is idling. When the speed in a certain gear is lower than this threshold, the engine is prone to stalling. When decelerating, as long as the current speed is higher than the idle speed of the current gear, there is no need to press the clutch. When braking in the current gear, as long as the engine speed does not drop below idle, there is no need to press the clutch.

Differences Between Plug-in Hybrid and Hybrid Vehicles?

Below are the differences between plug-in hybrid and hybrid vehicles: 1. Charging Requirement: Hybrid electric vehicles do not require charging; they simply maximize the advantages of both the electric motor and the internal combustion engine to achieve fuel efficiency. Plug-in hybrid vehicles, on the other hand, require charging and can be used as pure electric vehicles for short-distance driving, thus consuming no fuel. 2. Energy Recovery Mode: Plug-in hybrid vehicles also feature an energy recovery mode, where under specific conditions, the vehicle can use fuel consumption to regenerate electrical energy. However, while plug-in hybrids have stronger battery storage capabilities, this also means they need to be charged and cannot be driven at any time, making them slightly more inconvenient to use.
