The reason the handbrake light occasionally illuminates while driving is due to brake fluid leakage. Solution for brake fluid leakage: It is necessary to go to a 4S shop for inspection and repair the leakage point, then replenish the missing brake fluid, and the handbrake light will return to normal and turn off. Electronic handbrake: The electronic handbrake can provide accurate parking force through the slope sensor by the controller. When starting, the parking control unit calculates information provided by the clutch distance sensor, clutch engagement speed sensor, throttle pedal sensor, etc. It automatically releases the parking brake when the driving force exceeds the driving resistance, allowing the car to start smoothly.

Can the car's charcoal canister be replaced?

Yes, the car's charcoal canister can be replaced. Replacement cycle for the charcoal canister: In fact, there is no fixed replacement cycle for the car's charcoal canister, and the vehicle's user manual does not specify how often the charcoal canister should be replaced. As a car owner, there is no need to replace the charcoal canister as long as it is not damaged. Some 4S shops may recommend replacing the charcoal canister every 40,000 to 60,000 kilometers, but this is only a conservative estimate of the canister's lifespan. Function of the charcoal canister: The activated charcoal canister is usually installed between the fuel tank and the engine. It utilizes the adsorption capacity of the internal activated charcoal to adsorb and store fuel vapors from the fuel tank. When the engine starts, the solenoid valve between the activated charcoal canister and the intake manifold opens according to the ECU's command. At this time, the fuel vapors in the activated charcoal canister are drawn into the cylinder along with the air under the vacuum pressure of the intake pipe to participate in combustion. This not only reduces unnecessary emissions but also lowers the engine's fuel consumption.

Will the touch-up paint on a new car show differences after a few years?

Will the touch-up paint on a new car show differences after a few years. Reasons why it can't match the original paint: After a car is repainted, it cannot achieve the same effect as the original. The factory-applied paint is high-temperature paint with excellent hardness because the car body is empty during baking, allowing temperatures to reach several hundred degrees. During touch-up painting, the car body has many components and equipment, making high temperatures impossible—only around 50 degrees Celsius—so the paint hardness cannot match the original. Layers of car paint: The paint applied on the automotive production line consists of four layers: the electrophoretic layer, primer layer, base coat layer, and clear coat layer. The electrophoretic layer is the "foundation," directly adhered to the metal car body, serving as anti-corrosion. The primer layer is applied over the electrophoretic layer. During application, the entire car body frame is fully immersed in a large pool filled with paint; the primer layer protects the electrophoretic layer and enhances corrosion resistance.

Are Chassis Bolts Important?

Chassis bolts are very important. Safety Hazards: Loose bolts can pose significant safety risks without the owner's awareness. Therefore, car owners must pay attention to the inspection of automotive screws, especially those on the chassis. Inspection Cycle: The chassis endures substantial vibrations, so the screws on the chassis are specially treated by manufacturers, with enhancements in steel quality, hardness, and shock resistance. Generally, screws won't come loose unless the vehicle is of very poor quality, so there's no need to worry excessively. The recommended frequency for inspecting automotive screws is every one to two years during a maintenance visit to a 4S shop.

Can You Turn on the Air Conditioner Directly After Starting the Car in Summer?

You should not turn on the air conditioner directly after starting the car in summer. Using the air conditioner in summer: When the external temperature rises above 35 degrees Celsius, the interior of a closed car can reach 65 degrees within 15 minutes, causing the emission of formaldehyde, benzene, toluene, xylene, etc., to be 5 to 7 times higher than normal. When you first get into the car, open the windows for ventilation for one to two minutes to allow the toxic air to dissipate before driving and turning on the air conditioner. Turning off the air conditioner in advance: Before reaching your destination, turn off the air conditioner in advance and keep the fan running. This not only helps avoid forgetting to turn off the air conditioner and starting the engine with it still running but also keeps the air vents dry, preventing moisture and bacterial growth.

Can You Release the Clutch Immediately After Shifting to Second Gear?

You should not release the clutch immediately after shifting gears. Instead, you need to slowly release the clutch pedal. If the clutch pedal is released too quickly, the vehicle may experience significant jerking. Starting on Flat Roads: After pressing the clutch and shifting gears, the car's speed has not yet increased, so the clutch should be released gradually. Releasing the clutch too quickly may cause the engine to stall. You can wait until the clutch is fully released before applying throttle, as coordinating the clutch and throttle requires relatively advanced driving skills. Starting on Slopes: Hill starts are one of the most challenging aspects of driving. Not only should you avoid releasing the clutch immediately, but even a gradual release can sometimes cause the engine to stall. The correct procedure is to slowly release the clutch until the engine begins to vibrate, then release the brake pedal and immediately press the accelerator to maintain momentum. If you're not confident, you can also use the handbrake to ensure driving safety.

What is the name of that behind the steering wheel?

The left side behind the steering wheel is called the light control lever, and the right side is called the wiper control lever. Light control lever: The function of the left lever is that pushing it upwards activates the right turn signal, pushing it downwards activates the left turn signal. Turning it to the first small notch switches on the parking lights, the second small notch switches on the headlights, and pulling it upwards activates the headlight flasher. Wiper control lever: Pushing the right lever downwards activates the wiper function, which is used during rain or when the windshield is not clear. Composition of the steering wheel: The steering wheel is mainly composed of a skeleton, foam, and corresponding mounting clips or screw holes for the driver airbag (DAB).
