automatictransmissionThe gear selector lever is equivalent to the gear lever of a manual transmission. Generally, there are the following gears: P (parking), R (reverse gear), N (neutral gear), D (forward), S (or2), which is the second gear ), L (or1, which is the first gear).
The correct use of these gears is important for driving automatic transmissions.carIt is especially important for the people, let us get familiar with the use of each gear of the automatic transmission.
Use of P (parking gear)
When the engine is running, as long as the gear selector is in the driving position, the automatic transmission car can easily travel. When parking, the selector lever must be pulled into the P position, so that the output shaft is locked by the parking brake device inside the transmission, and the hand brake is tightened to prevent the car from moving.
Use of R (reverse gear)
The R position is reverse gear. Please remember that automatic transmission cars cannot use semi-linkage like manual transmission cars, so pay special attention to the control of the accelerator pedal when reversing.
Use of N (Neutral)
The N position is equivalent to neutral and can be used when starting or towing. When waiting for a signal or traffic jam, always keep the gear selector in the D position and apply the brake at the same time. If the time is short, this is allowed, but if the stopping time is long, it is best to switch to the N position and tighten the hand brake. Because the gear selector is in the driving position, automatic transmission cars generally have a weak driving tendency. To step on the brake for a long time is equivalent to forcibly stopping this tendency, which makes the transmission oil temperature rise and the oil is easy to deteriorate. It is especially unfavorable when the air conditioner is working and the engin

To step on the brake for a long time is equivalent to forcibly stopping this tendency, which makes the transmission oil temperature rise and the oil is easy to deteriorate. It is especially unfavorable when the air conditioner is working and the engine idling is high.In order to save fuel, some drivers slide the selector lever to the N position when driving at high speed or downhill, which can easily burn the transmission because the output shaft of the transmission is at this time.Rotating speedIt is very high, but the engine is running at idling speed, the oil pump is insufficiently supplied, the lubrication condition deteriorates, and the transmission is easy to burn.
Use of D (forward gear)
When the gear selector is placed in the D position during normal driving, the car can automatically shift gears between 1st and 4th gears (or 3rd gears). D position is the most commonly used driving position. What needs to be mastered is: Since the automatic transmission determines the gear position according to the throttle and the speed of the vehicle, the accelerator pedal operation method is different, and the vehicle speed when shifting gears is also different. If you quickly depress the accelerator pedal at the start, the upshift is late, the acceleration ability is strong, and the accelerator pedal is released quickly after a certain speed, the car can immediately upshift, so that the engine noise is small and the comfort is good.
Another feature of the D position is the forced low gear, which is convenient for overtaking at high speed. When driving in the D position, quickly depress the accelerator pedal to the end and turn on the forced low gear.switchIt can automatically downshift and the car will accelerate quickly. After overtaking, release the accelerator pedal to automatically upshift.
The use of S and L low gear
The automatic transmission is in the low range in the S position or the L position, and can be used in situations such as slopes.Switching to S position or L position when going downhill can make full use of engine braking and avoid wheelsBrakeOverheating causes the braking efficiency to decrease. However, when changing from D position to S position or L position, the vehicle speed cannot be higher than the corresponding upshift vehicle speed, otherwise the engine will vibrate strongly, causing the transmission oil temperature to rise sharply, and even damage the transmission.
In addition, in rainy and foggy weather, if the road attachment conditions are poor, you can switch to the S position or the L position and drive in a low gear. Do not use the position that can automatically shift to prevent the car from slipping. At the same time, it must be kept in mind that when skidding, the gear selector can be pushed into the N position to cut off the power of the engine to ensure driving safety. (Dahe Net)
