There are two meanings for the 'set' button in a car. One is used when decelerating after setting the cruise control, and the other is to set the current speed as the cruise speed after temporarily canceling the cruise control. The button corresponding to 'set' is 'res'. The 'res' button also has two meanings: one is for accelerating after setting the cruise control, and the other is to resume the previously set speed after temporarily canceling the cruise control. Conditions for using cruise control: 1. Cruise control should be used on highways or fully enclosed roads; 2. Do not use cruise control in rainy or snowy weather; 3. Cruise control is prohibited on winding mountain roads or roads with too many curves.

What is the vehicle scrapping process?

Vehicle scrapping process: The vehicle owner applying for scrapping and renewal must fill out and stamp the "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" in duplicate. Apply at the registration acceptance counter. For vehicles that have reached the mandatory scrapping age, a "Vehicle Scrapping Notice" will be issued. For vehicles not yet at the scrapping age, the vehicle inspection counter will determine if they meet scrapping standards and issue a "Vehicle Scrapping Notice" if applicable. The owner then selects a qualified recycling company to dismantle the vehicle, presenting the "Notice". The recycling company verifies the "Notice", dismantles the vehicle, and takes photographs. The engine must be separated from the vehicle, with the engine block destroyed and the chassis cut. The owner submits the "Modification Form", "XX Province Vehicle Renewal Technical Assessment Form", "Scrapped Vehicle Recycling Certificate", and dismantling photos to the vehicle inspection counter. After verification and signing, the license plates are reclaimed, and the scrapping is processed according to regulations.

How to Test the Engine Oil Pressure Sensor?

The engine oil pressure sensor exhibits a linear relationship between pressure and output voltage, with pressure ranging from 0 to 10 bar and output voltage varying from 0.5 to 4.5 volts. First, turn the ignition switch to OFF, disconnect the wiring harness connector of the oil pressure sensor, then turn the ignition switch to ON. Measure whether the voltage between pin 3 (A24) of the connector and ground is the input voltage, and whether the voltage between pin 4 and ground is zero.

Can a C1 Driver's License Drive a 7-Seater Vehicle?

Here are some common misconceptions about driving with a C1 driver's license: 1. Not all sedans can be driven. Many car owners believe that as long as it's a sedan, they can drive it with a C1 license. However, it's important to remember that the length of such sedans must not exceed 6 meters. For example, extended versions of BMW, Lincoln, and other elongated cars cannot be driven. 2. Not all blue license plate vehicles can be driven. So-called blue plate vehicles are not just the small cars we commonly think of; there are many other types that people may not be aware of. The regulation states: the total weight of vehicles allowed to be driven with a C1 license must not exceed 4.5 tons, and the number of passengers must not exceed 9. Vehicles outside this range cannot be driven. 3. A C1 license does not permit driving motorcycles. Motorcycle licenses are either D or E, where E is for two-wheeled motorcycles, and D includes E and also allows driving three-wheeled motorcycles. To obtain a D or E license with a C1 license, you must apply for an additional license, which requires holding the C1 license for at least one year. A C1 license holder can drive C2 vehicles, but a C2 license holder cannot drive C1 vehicles. Without a D or E license, driving a motorcycle is not allowed. Violating traffic rules by driving without the proper license is considered unlicensed driving. According to Article 99 of the Safety Law, 'Driving a motor vehicle without obtaining a motor vehicle driver's license, or when the motor vehicle driver's license has been revoked or temporarily suspended, shall result in a fine ranging from 200 to 2,000 yuan and may also be subject to detention for up to 15 days.'

How to Check the Oil Level Using the Dipstick?

First, locate the dipstick handle in the engine compartment, pull out the dipstick, and use a tissue to wipe off as much oil as possible from the dipstick head. At this point, observe the position of the oil mark on the dipstick. Then, reinsert the cleaned dipstick back into its original position. By examining the oil residue on the dipstick, you can determine the highest oil level inside the engine. If the oil level is between the MIN and MAX marks, it indicates that the engine has the perfect amount of oil.
