hI is the abbreviation of 'high'. 'hi' means adjusting the air conditioning temperature to the highest setting, which is the maximum heating level. The automotive air conditioning system and daily usage instructions are as follows: Automotive air conditioning system: Referred to as car air conditioning; used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state; providing passengers with a comfortable riding environment and reducing travel fatigue; creating good working conditions for the driver and playing an important role in ensuring safe driving; generally includes refrigeration devices, heating devices, and ventilation devices; this integrated system makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally. Daily use of air conditioning: Choose the appropriate air conditioning temperature; in summer, many people like to set the temperature very low, but they may not realize that setting the temperature too low can affect health, so the air conditioning temperature must be adjusted appropriately; the most comfortable temperature for the human body is between 20 and 25 degrees Celsius, above 28 degrees Celsius, people will feel stuffy; below 14 degrees Celsius, people will feel cold; therefore, the air conditioning should keep the car temperature between 18 and 25 degrees Celsius, as too low a temperature can easily make people sick.

Differences Between Golf 7 and 7.5?

Golf 7 and 7.5 differences are as follows: 1. Different engines: The new Golf is equipped with Volkswagen's latest EA211 series engine, adopting multiple advanced technologies for stronger power and lower fuel consumption. 2. Different exterior designs: The Golf 7.5 features a new bumper design, new LED daytime running lights, a new air intake grille, and new wheel arch designs. It is the first to be equipped with a 12.3-inch large LCD screen, leather steering wheel, 9.2-inch LCD screen, and adds an in-car PM2.5 filter. The biggest highlight of this mid-term facelift is that the 1.4T model has been upgraded from the semi-independent suspension of the original Golf 7 generation to an independent suspension.

What does the S-D gear mean?

It indicates a manual-automatic transmission. The D gear is the drive gear, and S is the sport mode. When the gear lever is in D, it can be pushed to the right to enter manual mode, where '+' is for upshifting and '-' is for downshifting. The "S gear" is a (slow gear) mode designed to enhance engine power. The main difference between it and the D gear lies in the timing of the transmission's gear shifts: when the gear is in S, the transmission shifts at higher engine RPMs to meet the driver's demand for power. Below is additional information: 1. How a manual-automatic transmission works: Structurally, a manual-automatic transmission mainly consists of a regular gearbox (similar to a manual transmission), an electronically controlled clutch, an automatic gear-shifting mechanism, and an electronic control unit. The electronically controlled clutch automatically engages, disengages, or "slips" the clutch as needed. During operation, the transmission ECU controls a stepper motor to move the clutch fork, engaging or disengaging the clutch. The automatic gear-shifting mechanism automatically selects the appropriate gear as needed, typically using two stepper motors, both controlled by the transmission ECU. The gear lever setup is similar to that of a conventional automatic transmission, with no clutch pedal. 2. The difference between a manual-automatic transmission and a hydraulic automatic transmission: This transmission essentially uses automatic control to simulate manual gear shifting. Under normal driving conditions, it operates similarly to a hydraulic automatic transmission, so if stopped on a slope, you must apply the brakes to prevent rolling. When using manual mode, it feels like driving a manual transmission car, with very direct power delivery, eliminating the need to press a clutch pedal. Additionally, you don't have to shift gears sequentially—you can skip gears when upshifting or downshifting.

What is the actual fuel consumption of the Jetta?

For the manual transmission, the average fuel consumption is over 7 liters per 100 kilometers when the air conditioning is not in use. There is no single accurate figure as fuel consumption depends on numerous factors, including the age of the car, the driver's habits, usual driving environment, road conditions, etc. Below are some factors that may lead to increased fuel consumption: 1. Faulty or improperly adjusted ignition system; 2. Improper adjustment of the carburetor main jet; 3. Excessive wear of pistons, piston rings, and cylinder walls; 4. Improper adjustment of the fuel pump and injector in the fuel injection system; 5. Poor sealing or excessive valve clearance in the valve mechanism; 6. Engine temperature being too high or too low.

What to Do When the Car Door Won't Close in Cold Weather?

Solutions for a car door that won't close in cold weather: 1. Drive the vehicle to a relatively warm underground parking lot and wait for the ice and snow to naturally thaw before closing the door; 2. Use a cloth dipped in hot water to melt the ice on the door. Note that before melting, you should manually remove larger chunks of ice to save time; 3. Use a hairdryer on the hot air setting to blow into the door gaps. Once the ice on the door melts, it can return to normal use. There are many reasons why a car door can open but not lock. If this happens in winter, the most common cause is the car lock cylinder freezing. You can pour hot water into the lock cylinder to thaw it. After thawing, remember to immediately dry the lock cylinder and add a little lubricant to prevent future freezing. Also, check if the car lock itself is malfunctioning. If so, repair it as soon as possible.

How often should the coolant be replaced in the Lavida?

The coolant in the Lavida should be replaced every 4 years or 60,000 kilometers, with a replacement capacity of 4L. Coolant, which has antifreeze properties, prevents the liquid from freezing during cold winter stops, thereby avoiding damage to the radiator and engine cylinder block or head due to expansion from freezing. Many people believe that coolant is only necessary in winter, but in fact, it should be used year-round. The Lavida is a compact car launched by SAIC Volkswagen, with dimensions of 4670mm in length, 1806mm in width, and 1474mm in height, and a wheelbase of 2688mm. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum power of 83kw, and is paired with either a 5-speed manual or a 6-speed automatic transmission.
