How to turn off the automatic transmission: operation steps and analysis of common problems
With the popularity of automatic transmission vehicles, many novice drivers have questions about the operation of automatic transmission stalling. This article will explain in detail the correct shutdown steps, precautions and common problems for automatic transmission vehicles to help car owners avoid operating misunderstandings.
1. Standard operating procedures for automatic flameout
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1 | After the vehicle comes to a stop, apply the brakes | Make sure the vehicle is completely stationary and avoid operating on slopes |
| 2 | Shift into N gear (neutral) | Wait briefly for the gearbox to unload. |
| 3 | Pull up the electronic handbrake | Robotic brakes require the handbrake lever to be pulled up |
| 4 | Shift into P gear (park gear) | Protect gearbox locking mechanism |
| 5 | Turn off electrical equipment such as air conditioners | Reduce battery load at next start |
| 6 | Press the brake, press the start button to turn off the engine | The key needs to be turned to the OFF position to start the vehicle |
2. Special operating requirements of different models
| Vehicle type | special operations | Principle description |
|---|---|---|
| Keyless start models | Need to press and hold the start button for 2 seconds | Prevent flameout caused by accidental touch |
| Hybrid/new energy models | Need to shut down the power system first | High voltage system safety protection |
| Equipped with automatic parking function | Need to close AUTOHOLD first | Avoid electronic system conflicts |
3. Common incorrect operations and hazards
1.Put it directly into P gear and turn off the engine.: It may cause the transmission gear to be overstressed, which may damage the locking mechanism for a long time.
2.No handbrake on slope: The weight of the entire vehicle is borne by the P gear ratchet, which can easily cause mechanical damage to the gearbox.
3.Electrical equipment is not turned off: Continuous power consumption of high-power electrical appliances may cause the battery to lose power, affecting the next startup.
4. Statistics of professional maintenance suggestions
| Fault type | Proportion of incorrect operations | average repair cost |
|---|---|---|
| Gearbox locking mechanism damaged | 43% | 2000-5000 yuan |
| Premature aging of starter motor | 27% | 800-1500 yuan |
| Abnormal battery loss | 30% | 400-1000 yuan |
5. Guidelines for handling special situations
1.Emergency flameout: When a fault occurs while driving, you can press and hold the start button for 3 seconds to force the engine to turn off, but the steering assistance will be lost.
2.Intelligent start-stop system: For vehicles equipped with this function, the engine will automatically shut down when temporarily parked without additional operations.
3.Forgot to turn off the engine and leave the car: Some models will issue an alarm prompt, and the latest models support the automatic flameout function.
6. Latest technology development trends
New models launched by many car companies in 2023 are already equipped withIntelligent flameout system, automatically determines the parking status through sensors, and no manual operation is required when the following conditions are met:
| Judgment conditions | Technical implementation |
|---|---|
| Driver leaving seat detection | seat pressure sensor |
| Door open status | Door lock sensor system |
| Keep keys away from vehicle | Bluetooth signal strength detection |
Correctly mastering the automatic transmission and flameout method can not only extend the life of the vehicle, but also ensure driving safety. It is recommended that car owners regularly participate in vehicle training organized by the brand to understand the special operating requirements of their vehicles.
