When the engine oil light illuminates in cold weather, it could be due to: 1. The engine temperature being too high, causing the oil to thin and leak excessively through the gaps, leading to a drop in oil pressure; 2. Insufficient oil quantity, resulting in the oil pump delivering less oil or failing to pump oil due to air intake, causing a decrease in oil pressure; 3. Damage to oil pump components or excessive gaps caused by wear or assembly issues, leading to the oil pump failing to deliver oil or delivering insufficient oil. The functions of engine oil include: 1. Alleviating friction and high temperatures; 2. Reducing gas leakage and preventing contamination from external pollutants; 3. Preventing contact between water, air, acidic harmful gases, and engine components; 4. Buffering the pressure rise at the engine cylinder ports; 5. Flushing away dirt generated on the surfaces of components.

What to Do If You Forget to Return the Card When Exiting the Highway?

The handling methods for forgetting to return the card when exiting the highway are: 1. If you intentionally avoid paying the highway toll or use other means to underpay, you will be fined three times the toll fee, and it may even affect your next highway entry; 2. If you fail to return the card due to special circumstances, you can return it promptly without penalty. If returning the card is inconvenient, you may use other methods such as mailing it back. You can leave your contact information and explain the situation in the mail. A highway is a multi-lane road exclusively designed for directional and lane-specific vehicle travel, with fully controlled access. The average annual daily traffic volume on a highway should ideally exceed 15,000 passenger cars, with a design speed of 80 to 120 kilometers per hour.

What Does a Spare Tire Mean?

A spare tire refers to an additional tire prepared for a car. In case of a flat tire or any issue with a wheel, the spare tire can be promptly replaced to prevent the car from breaking down midway. The speed limit for a spare tire is no more than 80 km/h, and it should not be driven continuously for more than 80 km. The size of a spare tire is smaller than that of a regular tire, with differences in aspect ratio, width, or diameter compared to the tires in normal use. The varying friction coefficients of the four tires can pose risks if used for extended periods. Car spare tires are generally categorized into full-size spare tires, non-full-size spare tires, and run-flat tires. Tires are circular elastic rubber products mounted on various vehicles or machinery, typically installed on metal rims. They support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain the vehicle's driving performance.

What is the difference between sport mode and normal mode?

Difference between sport mode and normal mode: 1. Different engine RPM: In sport mode, the engine RPM is generally higher, and the transmission gear is relatively lower; In normal mode, most engines shift gears when the RPM reaches around 2,000 per minute. 2. Different power output: Compared to normal mode, sport mode provides stronger power and more aggressive torque output; normal mode has a gentler torque output. When driving in normal urban areas, sport mode is not necessary, and it is generally used for highway driving or overtaking. In sport mode, the engine sound is louder, acceleration is faster, RPM is higher, and fuel consumption is greater.

What are the consequences of not paying compulsory traffic insurance for a year?

The consequence of not paying compulsory traffic insurance for a year is that the vehicle cannot be driven on the road. When there is a traffic police check at an intersection or an accident occurs, the traffic police will check whether the vehicle has compulsory traffic insurance. If the vehicle does not have compulsory traffic insurance, it will be impounded. Compulsory traffic insurance is a mandatory insurance required by the state. If you are caught by the traffic police without paying compulsory traffic insurance, in addition to the vehicle being impounded, you will also face a fine of twice the premium of the compulsory traffic insurance. During vehicle annual inspections and ownership transfers, the validity date of the compulsory traffic insurance is usually checked. If the vehicle has not been insured with compulsory traffic insurance or the insurance has expired, the annual inspection and ownership transfer cannot be processed. According to the compulsory traffic insurance rate fluctuation mechanism, if there are no claims for one year, the premium will be reduced by 10%; if there are no claims for two consecutive years, the premium will be reduced by 20%; and if there are no claims for three consecutive years or more, the premium will be reduced by 30%. If the compulsory traffic insurance is discontinued, some insurance companies may no longer provide discount benefits.

What is the beginner's mantra for coordinating clutch and throttle?

The beginner's mantra for coordinating clutch and throttle is: Use your left foot to control the clutch, press the pedal with the ball of your foot while keeping your heel off the ground, and release it slowly after pressing quickly. First, apply a little throttle to reach around 1500 RPM, then slowly release the clutch. As the car is about to start, you can feel a slight vibration from the clutch pedal with your left foot. Continue to slowly release the clutch pedal—be sure to do it slowly—and the car will start smoothly. Once the clutch pedal is fully released, press the throttle to accelerate the car forward. It's important to note that your heel should move along with the ball of your foot until your left foot is completely lifted off the pedal. After fully releasing the clutch and removing your foot from the pedal, use your right foot to control the brake and throttle. When not accelerating, your right foot should always be ready on the brake, positioned to accurately press the brake when needed. Use your heel as a pivot point to switch between the brake and throttle pedals with your toes. Coordinate the throttle with both feet: first, increase speed with the throttle, then quickly release the throttle while simultaneously pressing the clutch all the way down with your left foot, shift gears, and slowly release the clutch to complete the gear-shifting coordination.
