When the vehicle's smart key runs out of battery, the key's transmission power becomes very low, making it difficult for the in-car sensor to detect it, and the one-button start cannot complete ignition. This method is the simplest and most direct, but it only works for manual transmission vehicles. It involves finding a few people to push the car together and then starting it. If you have a companion vehicle, you can use a tow start. This method is similar to push-starting, but using another vehicle for towing is often much easier and more convenient. You need to find a vehicle with a charged battery and a set of jumper cables. Open the hood to locate the other vehicle's battery, then connect the two batteries using the jumper cables.

As a veteran Roewe owner with over a decade of experience, I've encountered similar issues. When a Roewe RX5 fails to start, it's most likely caused by battery problems. An aged or uncharged battery can't provide sufficient voltage during startup. Another common cause is poor cable connections due to loose or oxidized terminals blocking current flow. Starter motor failure preventing engine rotation is another possibility - if you hear clicking sounds from the engine bay without ignition, the starter is probably jammed. First check battery voltage; if below 12V, recharge or replace immediately. If the battery tests fine, jiggle the key to check contact points. Remember to perform regular battery maintenance - don't wait until failure occurs. High summer temperatures accelerate battery degradation, so pay extra attention during hot weather.

Failure to start can be caused by battery issues, starting system problems, ignition faults, or fuel system malfunctions. Taking the Roewe RX5 as an example, first check the battery voltage. If it's normal, then suspect a damaged or stuck starter motor. For ignition problems, spark plug carbon buildup or aging ignition coils can affect starting. Fuel system issues, such as clogged injectors or a failed fuel pump, prevent fuel from reaching the engine, causing failure to start. If accompanied by dashboard warning lights, there might be an ECU module fault. Avoid disassembling complex components yourself to prevent secondary damage. It's recommended to use a multimeter for simple checks, but for safety, drive to a repair shop for a comprehensive diagnosis.

It's quite frustrating when the Roewe RX5 won't start, and I've experienced it myself. First, consider the battery as the potential issue, such as a dead or aging battery. Try turning on the headlights or air conditioning to see if they work; if they don't, it's likely a battery problem. If the lights come on but the car still won't start, it might be due to a faulty ignition switch or poor cable connections. Occasionally, carbon buildup on the spark plugs can also cause this, though it's less common. You can check the battery terminals yourself to ensure they're secure by giving them a gentle shake. If all else fails, head to a repair shop promptly to avoid further complications.
