How many meters does it take to brake suddenly at a speed of 30 mph?

Can a temporary license plate be renewed if it has expired for 10 days?

Temporary license plates cannot be renewed if they have expired for 10 days, but you can apply for new ones. According to the relevant provisions of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses": After purchasing a motor vehicle, the owner can apply for temporary license plates up to three times before registration, each valid for no more than 15 days. However, already issued temporary license plates cannot be extended. Documents required for applying for temporary license plates: To apply for temporary license plates, you will need the purchaser's ID card, vehicle purchase invoice, compulsory traffic insurance policy (copy), and the vehicle's factory certificate. Copies of all four documents must be provided. Types of temporary license plates: Those with a sky-blue background, black characters, and black borders are limited to driving within the city, known as local temporary license plates. Those with a brown-yellow background, black characters, and black borders can be used for cross-city driving, known as intercity temporary license plates. Besides temporary plates for ordinary family cars, there are also temporary plates for test vehicles and special-type motor vehicles. Their appearance is similar to ordinary temporary plates but usually includes the characters "test" or "special" as an identifier.

What is the KL15 line?

KL15 represents the engine ignition signal (corresponding to the IGN state of the car key), and also indicates the signal for turning the key to start the car. Most ECUs require the car to be in the started state to operate, such as the ECUs of the chassis system, ABS, ESP, ABM, etc. KL15R (R stands for Radio) is when the key is turned to the position where the radio works (corresponding to the ACC state of the car key), but the car has not yet started, for example, the dashboard and windows receive this signal. This signal is powered by the ZentraleElektrik (the main electrical box in the car), and is connected to the KL15 pins of each ECU through a fuse. KL30 is the ECU power supply (i.e., connected to the car battery), providing the operating voltage for the ECU, generally between 11V and 15V. Some ECUs can operate when the car is turned off (corresponding to the OFF state of the car key), such as the Body Control Module (BCM). KL31 is the ECU ground source. The KL31 signal is connected to the common ground terminal of the car, usually marked with a W, such as W4 indicating the ground terminal of the engine shield. There are usually several common ground terminals in a car, located near the engine, dashboard, undercarriage, roof, and rear compartment, used for ECU common grounding to maintain consistent ground voltage.

What causes the Volkswagen Polo transmission to make noise and jerk?

The reasons for the Volkswagen Polo transmission making noise and jerking are: transmission valve body, transmission computer, internal friction plates of the transmission, and clutch failure causing the transmission to jerk and make noise. The transmission is a mechanism used to change the speed and torque from the engine, and it can fix or change the gear ratio between the output shaft and the input shaft. Taking the 2019 Volkswagen Polo as an example, its body dimensions are: length 4053mm, width 1740mm, height 1449mm, wheelbase 2564mm, fuel tank capacity 42.5l, and luggage compartment capacity 310 to 1003l.

How Many Years Can Bodywork and Painting Last?

Bodywork and painting with poor technique and improper maintenance may develop issues within 1-2 years; with good technique and proper maintenance, it can last around 5-6 years. Inspection After Bodywork and Painting: Check the paint: After bodywork and painting repairs, inspect the smoothness of the paint and check for impurities such as pinholes or bubbles. During the repair process of body panel coatings, it is inevitable for some impurities and dust to be present in the air. If not handled properly, this dust can adhere to the paint. Check for color difference: After car painting, it is difficult to detect color differences between the new paint and the original paint. Even with better craftsmanship, it is challenging to achieve a perfect match with the original paint. When checking for color differences, perform the inspection in a bright environment to ensure a comprehensive evaluation. Check the gloss of the clear coat: The clear coat is the outermost transparent layer of the car paint. If the gloss of the clear coat is poor, it will affect the visual appearance. Before performing bodywork and painting, ensure the cleanliness of the bodywork's filtration system and check if the spraying pressure is normal. If these aspects are satisfactory, proceed to inspect the paint booth's water and micro-dust separator and the air compressor. This step requires the paint hoses to remain clean. Bodywork and painting have high requirements. Items such as paint hoses, paint mixing cans, and spray guns used during the process should be stored in clean areas. Besides maintaining cleanliness, all preparatory steps should be completed outside the paint booth before starting the painting process to avoid unnecessary contamination of the paint.

How many liters of transmission fluid does the ATSL require?

The Cadillac ATSL requires 7L of transmission fluid. If an automatic transmission fluid exchange machine is used, approximately 14L will be needed. Functions of the transmission: Changing the gear ratio; expanding the torque and speed of the driving wheels; enabling the vehicle to reverse; facilitating gear shifting or power output. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the gear ratio between the output and input shafts. It consists of a gear transmission mechanism and a control mechanism. Maintenance methods for automotive transmissions: Replace automatic transmission fluid every 12 months or 20,000 kilometers; avoid coasting in neutral; frequently check fluid levels; avoid skipping gears when upshifting; do not force the transmission into neutral; do not shorten the idle warm-up time; avoid gear grinding when shifting; clean the transmission; avoid driving immediately after starting without warming up; perform regular maintenance on the automatic transmission. Types of transmissions: Transmissions are categorized into manual and automatic types. Manual transmissions primarily consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. Also known as a gearbox, the transmission is an automotive component that alters the speed and torque from the engine and can fix or change the gear ratio between the output and input shafts. The transmission consists of a gear transmission mechanism and a control mechanism, with functions including enabling reverse driving, interrupting power transmission, and changing gear ratios.
