Are Spare Tires the Same as Regular Tires?

Car tires and spare tires are not all the same. Generally, passenger cars are equipped with one spare tire, which can be categorized into full-size spare tires and non-full-size spare tires. Full-size spare tires have the same specifications as the original car tires, while non-full-size spare tires differ in specifications to remind the owner to inspect and replace them promptly. The types of spare tires include: Full-size spare tires: Full-size spare tires have exactly the same specifications as the other four tires on the car and can replace any temporarily or permanently unusable tire. Non-full-size spare tires: The diameter and width of these spare tires are slightly smaller than the other four tires, so they can only be used temporarily and must be installed on non-drive wheels. Run-flat tires: Run-flat tires are also known as safety tires, commonly referred to as 'flat-proof' tires.

When the engine yellow light comes on in a new car, it indicates that there is an issue with certain components of the vehicle's engine. Below are the common reasons for the engine warning light to illuminate: Emission standards not met: Factors such as poor fuel quality, a malfunctioning catalytic converter, excessive carbon buildup in the intake manifold, clogged fuel injectors, faulty oxygen sensors, or occasional engine misfires can all trigger the engine warning light. Among these, poor fuel quality is the most common cause. Poor engine system performance: Issues like faulty throttle position sensors, air flow meters, crankshaft position sensors, or poor electrical connections can lead to the engine warning light turning on. Transmission system malfunction: In some vehicles, transmission system problems such as internal failures, slipping, or overheating are also indicated through the engine warning light.

Why can't the spare key unlock the car door?

It may be due to an incorrect spare key or a blocked car keyhole. It is recommended to seek professional maintenance personnel for inspection and repair. The following explains the reasons why the remote key cannot unlock the car door: Remote lock failure: If the remote key cannot unlock the car door, it is likely due to remote lock failure or factors such as aging of the car's remote transmitter antenna, which renders the remote key ineffective. In this case, you can use the spare mechanical key to unlock the door. Magnetic signal interference: Another reason could be strong magnetic signal interference around the car. Since smart keys use low-intensity radio waves, they cannot function properly under magnetic interference.

What to Do If You Fail the Subject 4 Exam?

Subject 4 shares many similarities with Subject 1 in terms of test items, but Subject 4 focuses more on practical driving experience. Therefore, during preparation, it's essential to review questions thoroughly, practice extensively, and consider how you would react as a driver in similar real-life situations. This approach not only reinforces your understanding of the questions but also greatly benefits your future driving on the road. Subject 4 is just "one step away" from obtaining your driver's license—passing it will make your dream come true. However, if you fail the Subject 4 exam, don't lose heart or be discouraged. Remember, as long as you are within the 3-year validity period of the driving test, the number of retakes for Subject 4 is unlimited, unlike Subjects 2 and 3, which allow only 5 attempts. The 3-year validity period starts from the date you passed Subject 1, not from the date of your driving test registration. During the exam, face the test content head-on without avoidance. Reflect on your mistakes and deductions from each attempt, adjust your mindset, and strike while the iron is hot. Don't give up hope—trust in your abilities and maintain a positive attitude. Take the exam seriously in terms of tactics but lightly in strategy. Don't fear the test. Persistence leads to victory! Everyone is a winner!

Does Using the Heater in Winter Increase Fuel Consumption?

Using the car heater does not consume any fuel. Here's a detailed explanation: Principle of the Heater: The heat generated by the heater actually comes from the engine's heat. If the driver doesn't use the heater in summer, the heat is dissipated through the radiator cooling cycle. When using the heater in winter: Part of the heat generated by the engine is used to cool the engine after passing through the radiator, while another part enters the car's interior through the heater ducts. Therefore, using the heater in winter does not increase the vehicle's fuel consumption. The so-called increase in fuel consumption is because it takes longer for the engine to reach its normal operating temperature in winter compared to spring, summer, and autumn, which naturally leads to higher fuel consumption, but this is unrelated to using the heater.
