Why Do I Always Feel Extremely Sleepy While Driving?

Do new cars still need a break-in period?

After purchasing a new car, a break-in period is necessary. Before leaving the factory, manufacturers conduct a cold break-in for the engine without any load, but other components are not broken in, so further break-in is required for new cars. Additional information: Below are precautions during the car break-in period: 1. Shift gears promptly: If driving a manual transmission model, ensure timely gear shifting during driving to allow even break-in for each gear. 2. Avoid overloading the new car: Overloading can damage mechanical parts. Therefore, within the first 1000 kilometers, domestic cars should not exceed 75% to 80% of the rated load, while imported cars should not exceed 90% of the rated load.

How deep does water need to be to affect a car?

Water as shallow as 20 centimeters can affect some cars, while for vehicles with higher ground clearance, water up to 30 centimeters deep may cause issues. Water can backflow into the engine through the exhaust pipe, leading to stalling or even engine damage. When driving through flooded roads, it's advisable to use a low gear and proceed slowly. A crucial reminder: never lift your foot off the accelerator when crossing waterlogged areas, as this can create strong suction in the exhaust system that normally expels gases during acceleration, potentially drawing water into the engine. Here are some additional tips: 1. Towing assistance: If your car gets flooded, do not attempt to restart it as insurance won't cover such damage. It's best to call for towing service. 2. Check license plates: Verify if your license plates have been washed away. 3. Contact your insurer: Immediately notify your insurance company to file a claim, follow their procedures, and ensure you report the incident within 24 hours. 4. Prompt repairs: Arrange for repairs as soon as possible after water exposure. 5. Avoid restarting: If your engine stalls during water crossing, never attempt to restart it.

After pledging these documents, the toll station will let you pass, and you can retrieve them upon paying the cash later. 3. Call your insurance company: Insurance companies often provide free services within a certain range, such as roadside assistance, fuel delivery, or tire replacement. You can also exchange for cash when receiving these services from your insurer.

Can license plates be transferred to a used car?

License plates can be transferred to a used car. After the original owner has used the license plates for more than 3 years, they can apply to retain the license plate number for six months when selling or transferring the vehicle. During this period, if the original owner purchases a used car, they can apply to use the previous license plate number. The following are the conditions that must be met to apply for the use of the original motor vehicle license plate number: 1. The application must be submitted within six months after the transfer or cancellation of registration; 2. The original motor vehicle must have been owned by the applicant for more than three years; 3. All traffic violations and accident-related issues involving the original motor vehicle must be resolved.

Penalties for driving without a driver's license: If the driver provides the license: In the absence of other traffic violations, a fine ranging from 20 to 200 yuan will be imposed, 1 point will be deducted, and the vehicle will be returned. If the driver provides the license but has other traffic violations: Penalties will be imposed based on the circumstances along with the penalty for not carrying the license, and the vehicle will be returned. If the driver cannot provide the license: Penalties for driving without a license will apply, including a fine ranging from 200 to 2000 yuan and detention for up to 15 days. 2. If you don't have your driver's license, you can present the 12123 electronic driver's license: Presenting the 12123 electronic driver's license is also recognized by traffic police, but it is only applicable in certain regions where electronic licenses are enabled.

What to Do About Severe Jerking During Buick LaCrosse Acceleration?

Here are solutions for severe jerking during Buick LaCrosse acceleration: 1. Adjust Shift RPM: The shifting method involves first increasing the RPM to 2000 before shifting. For some models, the torque output at this RPM may be relatively too high for the power required by the moving vehicle, potentially causing jerking. Therefore, it's necessary to moderately reduce the engine RPM during shifting, such as shifting at 1500 RPM. For large-displacement engines or those with good low-RPM torque, shifting can even be done at low RPMs of 1000-1200 without causing jerking, with minimal impact on acceleration. So, if you frequently experience jerking during shifts, try adjusting (lowering) the engine RPM during shifting to find a level that allows smooth gear engagement without affecting continued acceleration. 2. Adjust the Gear Engagement Sequence to a Progressive Style: Progressive shifting means following the sequence 1-2-3-4-5. In certain situations, using a skip-shift method can also avoid jerking, such as shifting directly from 2nd gear at 2000 RPM to 4th gear, or from 3rd gear to 5th gear. This is based on the principle that the front-end torque output of the powertrain roughly matches the rear-end torque demand, and it is often used more during acceleration on highways or flat roads.
