Can You Drive with Insufficient Engine Coolant?

What Causes Steering Wheel Vibration When Speed Exceeds 100 km/h?

Steering wheel vibration when speed exceeds 100 km/h is mainly caused by poor tire dynamic balance, significant differences in tire pressure among the four tires, or improper wheel alignment. Poor tire dynamic balance: During driving, if a tire is subjected to a strong local impact, it may cause the balance weights to fall off or become damaged, thereby affecting the tire's dynamic balance. When driving at high speeds, the driver will feel noticeable vibration in the body and steering wheel, which becomes more pronounced as the speed increases. Significant differences in tire pressure among the four tires: When there is a considerable difference in tire pressure among the four tires, especially between the left and right tires, the car will experience noticeable bumpiness and steering wheel vibration at high speeds. Improper four-wheel alignment: When the four-wheel alignment has significant deviation angles, the car will exhibit phenomena such as body drift and vibration during high-speed driving. Additionally, it can lead to uneven tire wear, accelerating tire deterioration and shortening the tire's service life.

Is it allowed to reverse if you take the wrong lane at a highway exit?

It is not allowed to reverse if you take the wrong lane at a highway exit. Overtaking: Clearly identify the driving lane, overtaking lane, and road signs. On the highway, the lane closest to the central divider is the overtaking lane. If you are not overtaking, avoid staying in the overtaking lane for an extended period. Generally, the far-right lane is the emergency lane, and overtaking from the emergency lane is strictly prohibited. Driving speed: Pay attention to your driving speed. On the highway, driving slower is not necessarily safer. A speed of 80 to 100 kilometers per hour is considered relatively safe for small vehicles. Exiting the highway: When exiting the highway, make sure to identify the correct exit. If you miss your exit, continue driving and take the next exit. Remember, reversing or making a U-turn is strictly prohibited.

How Long Can You Drive After the Maintenance Reminder?

Car maintenance reminders do not affect normal driving safety, and there is no specific mileage limit. Engine Oil and Oil Filter Replacement: This primarily involves maintenance of the lubrication system, whose main function is to effectively lubricate various components of the car's engine to prevent excessive wear. The oil filter removes various impurities from the engine oil to ensure the proper functioning of the lubrication system. The oil filter should be replaced along with the engine oil during maintenance. Under normal circumstances, a car requires maintenance every 5,000 kilometers. Air Filter Replacement: The air filter cleans the air before it enters the cylinders, removing impurities such as dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is typically replaced after driving 20,000 to 25,000 kilometers. Spark Plug Replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission fluid, the battery, throttle body, fuel injectors, and brake pads are part of the inspection items during routine maintenance, and their maintenance depends on usage conditions.

Is Vehicle Annual Inspection Available on Holidays?

Vehicle annual inspection is normally available on holidays. Documents required for annual inspection: Original vehicle license, original and copy of the vehicle owner's ID card, unit certificate for company vehicles, and a copy of the compulsory traffic insurance policy. Inspection items: Check whether the exterior safety devices are complete and consistent with the registration photo on the vehicle license; pay fees, enter annual inspection information, conduct online inspection. If the vehicle fails, it must be self-inspected first before being submitted to the inspection station for re-inspection. Conditions for annual inspection: All traffic violations must be resolved before the vehicle is eligible for annual inspection. The inspection cannot be delayed even for one day. Vehicles can undergo annual inspection up to 60 days in advance, so it is important to arrange the time reasonably and avoid overdue inspection.

Will a Car's Chassis Be Damaged If One Side Falls into a Ditch?

If one side of a car falls into a ditch, it will not cause significant damage to the chassis. Introduction to Car Chassis: The car chassis consists of four parts: the transmission system, the running gear, the steering system, and the braking system. The chassis serves to support and install the car engine and its various components and assemblies, forming the overall shape of the car. It also receives the power from the engine to enable the car to move and ensure normal driving. Precautions for Driving: When driving, maintain a normal speed and avoid speeding, especially on rainy, snowy, or poor road conditions. If the vehicle starts to skid, adjust promptly to avoid accidents. Be particularly cautious when driving on muddy roads and slow down.

Should You Shift to Neutral (N) When Stopping at a Red Light with an Automatic Transmission?

It is not necessary to shift to Neutral (N) when stopping at a red light with an automatic transmission. Automatic transmission gear shifting: Automatic transmission vehicles have protection and interlock mechanisms for gear shifting. Shifting from Drive (D) to Reverse (R) or Park (P) by mistake can be dangerous while driving, but you can freely shift between Drive (D) and Neutral (N), even while the vehicle is in motion. Avoid coasting in neutral: Coasting in neutral with an automatic transmission does not save fuel. Prolonged coasting in neutral can lead to insufficient oil pressure in the hydraulic lines of the automatic transmission, which not only increases friction and reduces lubrication effectiveness but also damages the friction plates inside the transmission.
