Manual transmission works by shifting the gear lever to switch the driving gears on the intermediate shaft. Through different combinations of gear sizes meshing with the power output shaft, it alters the torque and rotational speed of the drive wheels. The functions of a manual transmission are: 1. To change the transmission ratio, expanding the range of torque and speed variation of the drive wheels to adapt to frequently changing driving conditions; 2. Under the premise that the car engine's rotation direction remains unchanged, to use the reverse gear to achieve backward driving; 3. With the engine still running, to use neutral gear to interrupt power transmission, which is beneficial for engine starting, warming up, idling, and facilitates gear shifting, coasting, or temporary parking; 4. To drive other mechanisms through the transmission's power output, such as the winch of certain vehicles or the oil pump of dump trucks.

How to Turn on the Low Beam Headlights on the Atenza?

Atenza's method of turning on the low beam headlights is to rotate the knob on the turn signal lever counterclockwise to the end, then pull the lever toward the steering wheel. Low beam headlights are designed for close-range illumination, with a large coverage area and short illumination distance, and the focus cannot be adjusted. The Atenza has a length, width, and height of 4870mm, 1840mm, and 1445mm respectively, a wheelbase of 2830mm, a minimum ground clearance of 162mm, and a fuel tank capacity of 56.2 liters. This car is equipped with a 2.0L naturally aspirated engine, with a maximum power of 116kW, a maximum power speed of 6400rpm, a maximum torque of 202Nm, and is paired with a 6-speed manual/automatic transmission.

Can the transmission side cover be damaged while driving?

Vehicle driving will not damage the transmission side cover, but if the transmission side cover hits a road protrusion while driving, it may cause damage. The transmission, also known as the gearbox, is an automotive component used to alter the speed and torque from the engine, and can fix or change the gear ratio between the output shaft and input shaft. The transmission consists of a gear transmission mechanism and an operating mechanism, with some vehicles also having a power output mechanism. It can be categorized into stepped, continuously variable, and integrated transmissions, featuring functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios. The transmission is a crucial component in vehicles, capable of altering the gear ratio and expanding the driving wheel's torque and rotational speed.

What is the procedure for replacing the rear brake pads on the Atenza?

The procedure for replacing the rear brake pads on the Atenza is as follows: 1. Remove the wheel and take off the dust cover; 2. Remove the caliper fixing bolts and take off the brake caliper; 3. Remove one of the fixing bolts on the brake caliper, and use a flat-head screwdriver to apply force to the caliper, allowing the brake cylinder piston to retract automatically; 4. Take out the brake pads. Alternatively, you can use a piston adjustment tool to press back the brake cylinder piston, then remove and insert the new brake pads. The Atenza is a mid-size car produced by FAW Mazda, with dimensions of 4870 mm in length, 1840 mm in width, and 1445 mm in height, and a wheelbase of 2830 mm.

Can You Drive with Low Tire Pressure in One Tire?

A tire with low pressure should not be driven on. Generally, the normal tire pressure for passenger cars is between 2.1 and 2.8 bar. If the pressure in one tire drops below 1.2 bar, you should avoid driving further, as it can lead to serious problems. Driving with low tire pressure causes significant damage. The tire's self-friction coefficient increases, and the flattened tread in contact with the ground creates an abnormal motion compared to the non-contact tread, preventing the tire from rolling smoothly and causing temperature rise. Low tire pressure also increases tire deformation, leading to sidewall cracks and excessive flexing, which generates heat, accelerates rubber aging, weakens the tire's internal structure, and increases the risk of tread separation. Additionally, it enlarges the tire's contact patch, accelerating shoulder wear and increasing the likelihood of a blowout.

What series of LLumar window films are generally used by 4S stores?

LLumar's exclusive supply for 4S stores includes three main series: Zunyi, Changyi, and Siyi. Here is more information about LLumar: 1. Automotive window films: Thermal insulation performance is the most important. 2. Thermal insulation performance: Among the products exclusively supplied to 4S stores, the Zunyi series outperforms the Changyi series, which in turn outperforms the Siyi series in terms of thermal insulation. 3. Functions: LLumar products are installed on the inner side of the glass and primarily serve to block solar heat, thereby reducing heat damage to in-car instruments, lessening the burden on the engine, and creating a comfortable driving space. LLumar films also reduce glare, prevent blurred vision and visual fatigue, block UV rays that harm the skin, and provide a certain level of tint for privacy protection.

How Long After Eating Fermented Rice Balls Can You Drive?

It is best to wait 24 hours before driving. Although the alcohol content in fermented rice balls is not high, it can still be detected in the human body. Wait until it has been metabolized before driving. In fact, many foods in daily life contain alcohol, such as fermented rice balls, liquor-filled chocolates, etc. It is best for drivers to avoid consuming these foods. Here are some relevant details: 1. After 24 hours: Although the alcohol content in these foods is low and driving may not necessarily lead to accidents, if you are stopped by traffic police and tested, your driver's license could be revoked. Therefore, it is safest to wait 24 hours, by which time the alcohol will have been metabolized and expelled from your body. 2. Precautions: Even so, you should always be mindful in daily life and never drive a motor vehicle or even an electric bike after consuming alcohol.
