What do the plus and minus signs on an automatic transmission car mean?

Automatic transmission cars with plus and minus signs on the D gear are equipped with a manual-automatic transmission, which is a type of automatic transmission. Here is the relevant information: 1. First, pull the gear lever down to engage the "D" gear, then push the lever to the left until "M/S" lights up, indicating that the manual mode is engaged. When you need to shift gears, push the lever forward to downshift and pull it backward to upshift. Note that if your vehicle speed and engine speed do not meet the requirements, you will not be able to upshift. Every operation must be approved by the transmission control unit. 2. The D gear of an automatic transmission car does not have the engine braking function and will continuously shift to higher gears as the downhill speed increases, making the car go faster and faster. You must constantly use the foot brake to control the speed, which can easily cause the brakes to overheat and fail due to excessive use, which is very dangerous. Therefore, when driving an automatic transmission car on a long downhill slope, do not use the D gear.

Can AWD be used when driving on the highway?

AWD can be used when driving on the highway, as it is suitable for low-load conditions and can perform effectively at high speeds. The center differential lock in an AWD system uses a multi-plate clutch structure, similar to a manual transmission clutch. Once engaged, it transfers power to the rear wheels. This type of multi-plate clutch center differential is compact, electronically controlled, and commonly used in family vehicles. AWD automatically switches to four-wheel drive only when necessary, otherwise remaining in two-wheel drive. It adjusts between two-wheel and four-wheel drive based on road conditions without requiring manual intervention. Unlike part-time 4WD, which requires manual switching between two-wheel and four-wheel drive, and full-time 4WD, which operates in four-wheel drive under all conditions, AWD is designed for automatic adaptation.

Can Front and Rear Tires of a Car Be Swapped?

Front and rear tires of a car can indeed be swapped. Typically, the first rotation should be done at 5,000 kilometers for new cars or new tires, followed by subsequent rotations every 10,000 kilometers. A four-wheel alignment is recommended at 30,000 kilometers or when installing new tires. Tires have different parameters such as toe-in, camber, load, tire pressure, whether they are drive or driven wheels, braking, and cornering grip. After a certain mileage, uneven wear occurs on the inner and outer edges of the tires as well as between the front and rear tires, necessitating rotation and four-wheel alignment for adjustment. The replacement interval for car tires depends on the tire's wear condition and its shelf life. The sidewall of the tire has a four-digit number indicating the manufacturing date, where the first two digits represent the week and the last two digits the year. Generally, tires should not be used for more than 3 years or exceed 60,000 kilometers in mileage.

What car brand is represented by a single vertical line?

A single vertical line represents the WEY brand. WEY is a Chinese luxury SUV brand, and its unique vertical logo originates from the iconic "Baoding Zhili Governor's Office Flagpole" in Baoding, China, the hometown of the founder Jack Wey and the birthplace of Great Wall Motors. This emblem embodies the pursuit and commitment of the WEY brand. WEY's product lineup includes: VV7, VV6, VV5, and the VV7 PHEV new energy series. Taking the WEY VV7 as an example: it is a mid-size SUV launched by Great Wall Motors, with dimensions of 4760mm in length, 1931mm in width, and 1655mm in height, and a wheelbase of 2950mm. It is equipped with a 2.0T turbocharged engine with a maximum power of 167kw, paired with a 7-speed dual-clutch transmission.

Where is the crankcase vent pipe of the Tiida located?

The crankcase vent pipe of the Tiida is located on the valve cover. The lower part of the cylinder block where the crankshaft is installed is called the crankcase, which is divided into the upper crankcase and the lower crankcase. The upper crankcase is cast integrally with the cylinder block, while the lower crankcase is used to store lubricating oil and seal the upper crankcase, hence it is also known as the oil pan. Below is an introduction to the functions of the crankcase: 1. The crankcase is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. 2. The crankcase is subjected to the combined effects of centrifugal force from rotating masses, periodic gas inertial forces, and reciprocating inertial forces, causing the crankshaft to bear bending and torsional loads. 3. It prevents the deterioration of engine oil. 4. It prevents leakage from the crankshaft oil seal and crankcase gasket.
