What are the differences between the VV5 and VV7?

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).

What is the break-in mileage for a new car?

New cars typically have a break-in mileage of 1,000-2,500 kilometers, while imported vehicles generally require a longer break-in period, usually between 1,500-3,000 kilometers. Stages of the break-in period: The break-in period consists of three stages. The initial break-in occurs within the first 100 kilometers of driving, the preliminary break-in is achieved at 200 kilometers, and an oxidation film forms after approximately 3,000 kilometers. Driving speed: It's advisable to maintain low speeds during the break-in period. Generally, the maximum speed for trucks shouldn't exceed 45 km/h, while passenger cars should stay within 50-80 km/h. Additional precautions: Avoid letting the engine idle for too long before starting - about 30 seconds is sufficient. Refrain from emergency braking during the first 300 kilometers of driving.

Why Can't a Motorcycle Start After Sitting for a Month?

The reasons why a motorcycle cannot start after sitting for a month are as follows: Fuel system reasons: Blockage in the low-pressure fuel line, loose pipes causing fuel leakage, air in the high-pressure fuel line, poor technical condition of the injector, and incorrect injection timing angle can all lead to the engine failing to start. Starting device reasons: Power supply failure, poor contact of the electromagnetic switch, poor contact between the starter motor commutator and brushes, slipping clutch in the starter transmission mechanism, and other reasons can also cause the engine to fail to start. Cylinder or air intake reasons: Damaged cylinder gasket causing air leakage, valves not sealing tightly leading to air leakage, worn piston cylinder causing air leakage, and clogged air filter element can also prevent the engine from starting normally.
