Automatic transmission car gear M is the manual mode gear. The M gear is generally found in cars with a manual-automatic transmission, where the gear lever needs to be manually shifted to change the gear engagement position inside the transmission, altering the gear ratio to achieve the purpose of shifting. Proper use of the M gear can provide sufficient power and a sense of control while driving. Scenarios for using the M gear: 1. Downshifting: When overtaking, if the gear is in D (Drive), the speed will not increase rapidly by pressing the accelerator hard, as it still shifts up sequentially, resulting in a slower response time. If switched to M gear, the driver can press the accelerator, and the vehicle can utilize the high torque of a lower gear to accelerate instantly, completing the overtaking maneuver more quickly, saving time and making overtaking safer; 2. Descending a slope: When an automatic transmission car is going down a long slope, the speed will continuously increase, requiring the use of brakes to control the speed. However, using the M gear to employ engine braking to reduce speed is safer and also prevents wear on the transmission; 3. Ascending a slope: When the vehicle is going uphill, traffic jams may occur. If driving a manual-automatic transmission vehicle, the gear can be kept in 1st gear.

What does it mean when the A/C button light is on in the car?

The A/C button light on in the car indicates that the air conditioning compressor is turned on, while the light being off means only the car's fan is blowing air. Principle of heating: The heating comes from the heat generated by the engine during operation. When the engine's cooling system dissipates heat from the engine, the fan directs this heat into the car, creating warm air. When the heating is not in use, the fan stops, and the heating vents close, allowing the dissipated heat to completely escape into the atmosphere. Therefore, car heating is a form of waste heat recycling and does not consume fuel. Pressing the AC button activates cooling: The AC button is the switch for the air conditioning compressor. In summer, when using the air conditioner, you must press the AC button to turn on the cold air. On the other hand, heating only utilizes the internal heat cycle of the car and does not require the air conditioning compressor to be activated. Thus, to turn on the heating, you only need to adjust the air conditioning button without pressing the AC switch.

Should I Put the Dual Clutch in N or D Gear at a Red Light?

When waiting at a red light with a dual-clutch transmission, keep it in D gear and press the brake. Once the car stops, you can release the brake. Do not shift to N gear; only turn it off if the red light is long. You can turn it off during stop-and-go traffic. Conceptual Differences: The N gear is neutral, which can be used when parking. Its essence is the neutral position in the transmission, designed to cut off the power transmission between the input and output shafts inside the gearbox. The D gear is the drive gear, but drive gears are not limited to D; they also include M, S, L, and numerically labeled restriction gears like 1, 2, and 3. Functional Differences: Both manual and automatic transmissions have an N gear. If the car is not secured with the handbrake after shifting to neutral, it may roll. Neutral can be used when waiting at a red light or during a short stop without turning off the engine. The D gear is the most frequently used gear in an automatic transmission, serving as the drive gear and is required for driving.

How often should the brake discs of Lavida be replaced?

Lavida brake discs should be replaced every 100,000 kilometers, but this also depends on driving conditions and habits, which can affect the wear of the brake pads. During routine inspections, pay close attention to the wear level of the brake pads. If they reach the critical point, they must be replaced immediately. If you hear a metallic scraping or squealing sound when lightly applying the brakes, or if you feel that the pedal requires more effort to achieve the usual braking effect, or if the pedal position is noticeably lower during emergency braking, it may indicate that the brake pads have lost their friction and need to be replaced. The Lavida has a body length of 4605mm, width of 1765mm, height of 1460mm, and a wheelbase of 2610mm. It is equipped with a mature and stable two-valve 2.0-liter engine. The onboard navigation system features a combination of touch screen and rotary knob controls, with a foldable LCD screen design.

What to Do When the Vehicle License is About to Expire?

The solutions for an expiring vehicle license are: 1. Participate in the motor vehicle inspection within 90 days before the expiration date; 2. For non-exempt vehicles, the owner should bring the authorization letter, vehicle license, and compulsory traffic insurance policy to the motor vehicle inspection station at the testing location for vehicle inspection. After passing the inspection, apply for the inspection qualification mark directly at the station; 3. For vehicles exempt from inspection within 6 years, the public security traffic management department will no longer inspect the motor vehicle when issuing the inspection mark. They will only review the motor vehicle inspection mark application form, vehicle license, compulsory traffic insurance certificate, vehicle and vessel tax payment or tax exemption certificate, and verify the handling of traffic safety violations and traffic accidents. If everything complies with the regulations, the inspection mark will be issued, noted on the supplementary page of the vehicle license, and the motor vehicle inspection mark application form will be stored in the motor vehicle file.

What is the Safe Following Distance on Highways?

Highway safe following distance varies depending on the situation: 1. When the speed exceeds 100 kilometers per hour, a distance of more than 100 meters should be maintained from the vehicle in front in the same lane; 2. When the speed is below 100 kilometers per hour, the distance from the vehicle in front in the same lane can be appropriately reduced, but should not be less than 50 meters. Precautions for driving on highways include: 1. Both the driver and front-seat passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid sudden steering wheel movements while driving at high speeds; 3. Do not change lanes arbitrarily while driving. When changing lanes or overtaking the vehicle in front, the turn signal must be activated in advance; 4. Only adjacent lanes are allowed for overtaking, and the vehicle should immediately return to the driving lane after overtaking. Vehicles must not ride or drive on the lane dividing line; 5. Do not reverse, drive in the opposite direction, cross the central divider to make a U-turn or turn, conduct test drives, drive training vehicles, or overtake or park on ramps.
