Dongfeng Citroen Picasso cold car will get hot if it doesn't hit the valve.

1. Is the steering wheel in a deadlock state? The solution is simple. As long as you hit the steering wheel hard and twist the key at the same time, you can usually unlock the steering wheel quickly, and ignition is an instant thing.

2. Didn't you put the gear back to P when parking? Think about it. If the ignition can be carried out in D or R range, the jumping of the vehicle at the moment of ignition is undoubtedly a huge safety hazard. Therefore, for automatic transmission vehicles (AT, CVT, AMT), manufacturers will preset this mode, and repeatedly inform in the manual: ensure that the gear position is in P gear when igniting.

3. One-button startup sometimes encounters the trouble that intelligent key has no electricity. Obviously the key is in the car, but the instrument keeps showing' key matching error'. This situation is probably due to the power failure in intelligent key, and the starting system can't sense the weak radio waves emitted by the key. So it is suggested to pick up intelligent key and put it on the start button, and then press the button to start.

4. Check whether the battery is charged. The failure to catch fire may be due to power failure or battery life expiration caused by long-term headlight failure. In general, the battery should be replaced in time according to the maintenance manual.

5. See if there is any oil. If the fuel gauge shows below the red line, it will naturally fail to catch fire. At the same time, pay attention to the quality of oil. A car owner opened the fuel tank and found that there was water and mud in it. With this kind of oil, it is impossible for the car not to break down.

6, without antifreeze

Some car owners add water or inferior antifreeze to the car, which causes the whole waterway to freeze. When it is particularly cold in winter, the engine freezes and cracks, resulting in the failure of the car water pump, which can't catch fire and hurt other parts of the engine.
