Methods to judge the distance between vehicles are as follows: 1. When the lower edge of the rear wheel of the car in front aligns with the lower edge of the windshield, the distance is 3-5 meters. 2. When the lower edge of the front car's bumper aligns with the lower edge of the windshield, the distance is about 2 meters. 3. When the upper edge of the front car's bumper aligns with the lower edge of the windshield, the distance is 0.5-1 meters. 4. When the image of the car behind occupies the entire rearview mirror, the distance is about 3 meters; when it occupies two-thirds of the rearview mirror, the distance is about 5 meters; when it occupies half of the rearview mirror, the distance is about 9 meters; when it occupies one-third of the rearview mirror, the distance is about 12 meters.

How is the fuel consumption of Corolla Hybrid when idling with air conditioning on?

Corolla Hybrid does not consume much fuel when idling with air conditioning on. The Corolla Hybrid is equipped with automatic air conditioning, which helps save fuel and reduces power loss when the air conditioning is in use. Here are some details about car air conditioning: 1. The temperature of the car air conditioning should be appropriate: The interior temperature should be maintained between 18°C and 25°C. Prolonged use of air conditioning can cause wear and tear to the cooling system, as the air conditioning is a heavy load on the engine, which itself is a heat source. In hot weather, this can reduce the efficiency of the air conditioning. Therefore, it is advisable not to use the air conditioning for too long at a time. If the interior temperature has reached a comfortable level, you can turn off the air conditioning and turn it back on after a while. 2. Do not smoke in the car with the air conditioning on: Smoking in the car can cause smoke to accumulate, irritating the eyes and respiratory system, which is harmful to health. If you must smoke, adjust the air conditioning ventilation control to the "exhaust" position to expel the smoke from the car. Avoid resting or sleeping for long periods in a stationary car with the air conditioning on.

What are the differences between the 2017 Jetta and the 2019 Jetta?

The main differences between the 2017 Jetta and the 2019 Jetta are as follows: 1. The 2019 Jetta comes with a multifunction steering wheel, while the 2017 Jetta lacks this feature. 2. The tire specifications of the 2017 Jetta are smaller than those of the 2019 Jetta. Taking the base model as an example: the front tire specification for the 2017 Jetta is 175/70-R14, and the rear tire specification is also 175/70-R14. In contrast, the front tire specification for the 2019 Jetta is 185/60-R15, and the rear tire specification is also 185/60-R15. 3. In terms of power, both models are the same, but the 2017 Jetta has an additional powertrain option. The additional powertrain consists of a 1.4T inline 4-cylinder turbocharged engine paired with a 7-speed dual-clutch transmission, delivering a maximum power of 96 KW and a maximum torque of 225 N·m. Regarding body dimensions, the length, width, and height are 4501/1704/1469 mm respectively, with a wheelbase of 2604 mm.

What Happens When Gasoline Quality is Poor?

Poor gasoline quality can lead to increased carbon deposits in the combustion chamber, cause knocking combustion, and result in reduced power and elevated temperatures. Below are the effects of gasoline quality on vehicles and the manifestations of fuel quality. Impact of gasoline quality on vehicles: Gasoline is the heart of a car, and whether its quality meets the national standards for automotive gasoline has a significant impact on the vehicle. Poor fuel quality can 'poison' the car, with minor effects like reduced acceleration and severe cases causing engine damage that requires disassembly for repair. Abnormal car malfunctions are often caused by the use of substandard gasoline. Manifestations of fuel quality: Standard fuel appears colorless, transparent, or golden yellow, while substandard fuel looks cloudy, dark, dull, and may contain suspended impurities. Qualified fuel has a faint, pleasant smell; substandard fuel, if diluted with water, may have a weak odor or extreme pungent and sour smells, leading to exhaust emissions with abnormal odors. Standard gasoline feels cool when dripped on the hand, while slow evaporation or residue indicates poor quality. Cars using substandard fuel may produce noticeable abnormal noises during driving, accompanied by vibrations. Shaking gasoline will produce bubbles; the faster the bubbles disappear, the better the fuel quality.

Can 3 points deducted for no annual inspection be deducted from someone else's license?

Can 3 points deducted for no annual inspection be deducted from someone else's license? As long as the fine is paid, the demerit point system will automatically reset the previous demerit points from the next demerit point cycle, i.e., the second year, after the fine is paid. Regulations on the deduction of points for motor vehicle driving licenses: If a motor vehicle driver's demerit points do not reach 12 points within a demerit point cycle and the imposed fine has been paid, the demerit points will be cleared. If the demerit points have not reached 12 points but there are still unpaid fines, the demerit points will be carried over to the next demerit point cycle. Precautions regarding the deduction of points for motor vehicle driving licenses: When a Class C driving license accumulates 12 demerit points within a demerit point cycle, the driver must attend a training course at the vehicle management office as required and then take an exam. The driving license can only be used again after passing the exam. During the period before passing the exam, driving on the road is not allowed, otherwise it will be considered as driving without a license.

What does 'cruise' displayed on the car mean?

cruise refers to the car's electronic cruise control system. Generally, when the vehicle speed exceeds 20km/h, pressing the cruise button will activate the cruise control mode, where the engine computer automatically controls the speed without the need to press the accelerator pedal. The driver only needs to steer the wheel. When the green cruise indicator light on the dashboard illuminates, it indicates that the cruise control switch is now activated. Below is a detailed classification of cruise functions: 1. Speed Cruise Control: This is the most common type. The basic operation involves activating the cruise mode and then selecting the desired speed, allowing the driver to release the accelerator pedal while maintaining the set speed. The speed can be adjusted using control buttons (or levers) during driving. To cancel the cruise setting, simply press the brake or turn off the cruise switch. 2. Speed Limiter Cruise: This is very similar to speed cruise control, with the key difference being that after setting the speed limit, the driver must keep their foot on the accelerator pedal to maintain the set speed. Once the set speed is reached, the computer automatically determines the required fuel supply. Unless the accelerator is pressed deeply and quickly, slight increases in the accelerator will have no effect. 3. Adaptive Cruise Control: The most notable feature of adaptive cruise control is the addition of radar or infrared detectors, giving the cruise system 'artificial intelligence.' It helps the driver maintain higher safety in conditions like fog or sandstorms and can perform advanced driving tasks such as following another vehicle, similar to an experienced driver.
