What Issues Should Be Paid Attention to During the Break-in Period of a New Car?

New car break-in period requires attention to the following issues: 1. The first 500 kilometers is the initial break-in phase, during which the speed should not be too high, generally kept below 70 to 80 km/h, and the engine speed should preferably not exceed 2,200 rpm; 2. From 500 to 1,000 kilometers is the mid-term break-in phase, where the maximum speed can be appropriately increased, generally up to 90 to 100 km/h, while the engine speed should still preferably stay below 2,500 rpm; 3. From 1,000 to 1,500 kilometers is the late break-in phase, during which the speed can be increased to below 120 km/h, and the engine speed should not exceed 3,000 rpm; 4. During the break-in period, it is not advisable to keep the speed below 60 km/h for extended periods; 5. Avoid driving at a constant speed for long durations during the break-in period; vary the speed instead; 6. Avoid sudden braking and rapid acceleration during the break-in period.

How to Steer the Wheel for Beginners?

Hold the left hand at the 9 o'clock position of the steering wheel and the right hand at the 3 o'clock position. This way, no matter how you turn the wheel, your hands will remain symmetrical after steering. Gripping too tightly can cause fatigue and make steering feel stiff, but holding it too loosely is also not advisable, as the wheel may deviate on uneven roads. When holding the wheel properly, your palms and fingers should be able to move freely. Avoid gripping the wheel backward or hooking it with your fingers, as this can hinder smooth turning and control. With practice, you will quickly become proficient and develop these good habits, which will instinctively help you react correctly in emergencies.

What to do if the 100-meter gear shifting exceeds 100 meters?

If the 100-meter gear shifting exceeds 100 meters, you should immediately downshift. When downshifting, do not release the clutch with your left foot; keep it pressed. The gear shifting test mainly assesses the driver's proficiency in vehicle gear operation. To pass smoothly, first ensure sufficient throttle input. After each gear change, decisively proceed to the next shifting action. This includes both hand and foot movements, which should be fast, accurate, and coordinated. Adjust gears reasonably based on road conditions and speed, ensuring timely and smooth shifting. Slow down where necessary and stop to wait when required, ensuring your next test item won't be affected by others.

How to Downshift from Third Gear to Second Gear?

After completing acceleration, immediately release the throttle and depress the clutch pedal, then gently push the gear lever from second gear back to neutral, pause briefly, and then shift forward into third gear. Next, while lightly pressing the throttle, quickly lift the clutch pedal to the semi-engaged state, and gently release the clutch pedal once the clutch is engaged. To switch from throttle to deceleration, first apply the brakes to slow down. After deceleration is complete, immediately release the brakes and depress the clutch, then gently shift the gear lever from third gear back to neutral. Follow the principle of "accelerate before upshifting, decelerate before downshifting." Gear changes should be timely, accurate, smooth, and swift. Upshifting should not skip gears, whereas downshifting can.

What to Do If a Car Fails the Exhaust Emission Test?

Insufficient ignition energy from spark plugs fails to completely burn the air-fuel mixture, resulting in excessive HC content in the exhaust. Poor atomization of fuel injectors or an overly rich air-fuel mixture can also lead to excessively high pollutant levels in the exhaust, causing the vehicle to fail the test. Therefore, it is essential to clean the fuel injectors regularly. The advantages of high-octane gasoline are mainly reflected in "two highs and two lows": higher anti-knock performance and power output, along with lower harmful substances in gasoline and reduced exhaust pollution. Neglecting the maintenance of the three-way catalytic converter can lead to its blockage, reducing its ability to convert harmful gases and ultimately causing the vehicle to fail the exhaust emission standards.

What is the process of ordering a car at a 4S store?

When conditions permit, request a test drive and negotiate the car price with the salesperson. After understanding the price and availability of the new car, negotiate the specific purchase cost and delivery time with the salesperson, then sign the car order contract. Arrive at the store to inspect and pick up the new car at the agreed delivery time specified in the contract. Check and confirm items such as the car body appearance, windows, door locks, and the onboard computer. The dealer will require the customer to confirm and sign the "inspection checklist" to indicate "the user confirms the new car is error-free." The salesperson will then arrange insurance for the new car.
