When the car maintenance warning light comes on, it indicates that there is an issue with the vehicle, alerting the owner to perform necessary repairs or maintenance. If the dashboard warning light illuminates, the driver should stop the car to inspect for any problems and promptly identify the issue or proceed directly to a repair shop for servicing to avoid potential accidents while driving, which could damage the vehicle. Details about common warning lights: 1. Oil Pressure Warning Light: Indicates that the oil level or pressure is below the standard value. Continuing to drive may cause the engine to lose lubrication, leading to severe wear. 2. Coolant Temperature Warning Light: Displays the temperature of the coolant inside the engine. 3. Engine Warning Light: Shows the working status of the engine, typically in yellow. When turning the key for the self-check, if this light remains on, it suggests there may be a fault in the engine system.

What Causes Electronic Parking Brake System Failure?

Electronic parking brake system failure is most likely caused by issues with the electronic parking brake itself, worn brake pads, problems with the electronic system, or battery power supply issues. It is essential to visit a repair shop to read the fault codes with a diagnostic scanner and perform repairs based on the fault codes. More relevant information is as follows: Solution: Reset the electronic parking brake by turning on the car key, pressing the foot brake, then holding down the electronic parking brake for 5 seconds and pulling it up for another 5 seconds. This will initialize and reset the electronic parking brake. Parking Brake: Usually refers to the manual brake installed in motor vehicles, commonly known as the handbrake. The typical handbrake is positioned within easy reach of the driver's right hand for convenience.

What does it mean when the car displays TC?

The car displaying TC refers to the Traction Control system. When the system is active, the yellow TC light on the dashboard flashes to alert the driver. The Traction Control system, also known as the Track Control system, relies on electronic sensors to detect if the driven wheels' speed is lower than that of the driving wheels. It then sends signals to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or apply braking to the wheels to prevent wheel slip. Possible causes for the TC light to illuminate include: 1. Solenoid valve malfunction; 2. Dirty engine oil clogging the solenoid valve filter; 3. Wear in the actuator gears or impeller causing oil pressure leakage and triggering the alarm; 4. Dirty throttle body with opening reaching 20%, leading the engine computer to misdiagnose a TC fault.

What is the correct way to use a seat belt?

Correct usage of a seat belt involves the following steps: 1. Close the car door securely; 2. Adjust the seat to a comfortable position; 3. Pull the buckle end of the seat belt downward along your body, ensuring the belt is not twisted and avoiding pulling too quickly to prevent the belt from locking; 4. Insert the buckle into the latch until you hear a click; 5. Gently tug on the buckle to confirm it is securely locked; 6. Adjust the lap belt by pulling downward on the buckle end and the shoulder belt by pulling upward to ensure the lap belt is snug. Seat belts function to restrain movement, absorb impact energy, and counteract inertia, thereby reducing or preventing injuries to vehicle occupants.

Is Electronic Eye Violation Random Sampling?

Electronic eye violations are not random sampling, and not all violations will necessarily be captured. Violation capture relies on electronic eyes, depending on whether there are capture devices at the violation location. However, electronic eyes do not capture all violations; it depends on whether the violation is obvious, as well as the system's judgment and manual identification of the violation behavior. With increasingly advanced monitoring equipment, the success rate of correct identification is also getting higher, so it is essential to comply with traffic rules. Methods of vehicle violation capture: Induction loop: One method involves underground induction loops with digital cameras mounted on crossbars to capture red-light running. Cameras: Another method uses mounted cameras for real-time recording of speeding, red-light running, illegal parking, etc.

What Causes a Car Horn to Stop Working?

The reasons why a car horn may stop working include: 1. Broken or disconnected power circuit to the horn; 2. Poor contact in the horn button; 3. Burnt or excessively gapped relay contacts; 4.

Restart the vehicle; 2. Check for faulty wiring; 3. Replace the amplifier. Precautions for using a car horn include: 1. Avoid getting the horn wet during car washing, and dry it promptly if it gets wet; 2. Do not press the horn for extended periods, as this can cause premature burning of the horn contacts.

How to Unlock a Car Tire That's Been Locked?

To unlock a car tire that's been locked, the methods are: 1. If you have the key, you can easily open it; 2. If you don't have the key, you need to seek professional help to unlock it, as you cannot open the lock yourself.

To directly contact the road surface and, together with the car suspension, mitigate the impact experienced during driving; 2. To ensure the car has good ride comfort and smooth driving; 3. To ensure good adhesion between the wheel and the road surface, improving the car's traction, braking, and passability; 4. To bear the weight of the car.
