4hw.com.cn: we have talked about the problem of waiting for a red light more than ten times. Many car owners don't know how to operate the problem. The answer on the Internet is one person for one, which is not difficult to solve.
The so-called automatic gear is that the vehicle will shift automatically in the process of moving, without the driver's manual operation. Automatic vehicles are also called 'stupid cars'. Of course, the title is more because many drivers don't understand the structure and principle of automatic transmission and mistakenly drive the automatic car as a 'fool's car'. In fact, this is not good for the power and safety of the car.
1. Gear d + brake: about 10 seconds
There are generally four gears in the automatic gear model, P, R, N and D, and D is the forward gear. Based on the principle of infrequent shifting, if the red light is very short, about 10 seconds, then there is no need to switch gears again. Just put D on the brake.
2. N gear + handbrake: more than 30 seconds
If the time of red light is more than 30 seconds, and the red light of some urban intersections can even reach 99 seconds, it is generally recommended to shift to n gear, i.e. neutral, and then pull the handbrake, so that you can release your feet for a little rest.
Simply put: wait for the red light, shift to N, pull the handbrake or D, and step on the brake.
As for whether it will hurt the gearbox if D gear is pressed on the brake for a long time (this long time is only applicable to traffic light waiting, not to deliberately challenge the gearbox limit), because of the hydraulic transmission, this need not be too worried, and the manual of automatic gearbox will not have such a warning.
As for whether the red light can be put into P gear or not, it is not recommended unless it is stopped for a long time, such as more than one or two minutes, or even longer.
Because from the D gear to the P gear, it actually has to go over three gears. If it is operated repeatedly, it is inevitable to wear the gearbox. In addition, to engage P gear, it is required to engage again when the vehicle stops completely, otherwise, it will cause greater damage to the gearbox.
