How to start the Roewe RX5 when the battery is dead?

If the Roewe RX5 battery is dead, you can use jumper cables to charge it. Here are a few precautions regarding jumper cables: 1. Before connecting the jumper cables to the donor vehicle, make sure to turn off the engine. After connecting the jumper cables to the donor vehicle, be careful not to let the positive and negative terminals touch each other, as a short circuit can be dangerous. 2. When removing the jumper cables, first disconnect the negative terminal, then the positive terminal. 3. If the dead vehicle still doesn't start, it may be because the dead battery has too little residual charge, and the donor vehicle's power may not be sufficient to start it, which is normal. In this case, you can charge the dead vehicle for a longer time (revving the donor vehicle's engine can speed up the charging process).
A dead battery is really frustrating, and I approach it from a safety-first perspective. First, don't panic. Make sure your car is parked in a safe spot without obstructing traffic, and set up warning signs to alert others. The most effective solution in this situation is to get a jump start from another vehicle: use jumper cables to connect the positive terminals of both batteries first, then attach the negative cable to the donor car's ground or negative terminal—be careful not to reverse the connections to avoid short circuits. Start the donor car, wait a few minutes, then start your Roewe RX5. If you don't have jumper cables, it's safer to directly contact a 4S shop or roadside assistance—they have professional tools. To prevent this, I recommend regularly checking your battery's lifespan; typically, it should be replaced every 3 to 5 years, and avoid leaving electrical devices on for extended periods. Learning these emergency procedures can help you avoid bigger headaches.
I once dealt with a dead battery issue myself, and the process was quite simple. Prepare jumper cables or a portable jump starter, like the small tool you can buy on JD for around 100 RMB. The steps are: connect the black cable to the ground of the donor car, and the red cable to the positive terminals of both cars—make sure not to mix up the polarity. Wait for the donor car to run for a while, then start your car, and remember to drive around for a bit to recharge the battery. For manual transmission cars, you can also push-start them—get a few people to push, put it in second gear, press the clutch, and release it to start. This method doesn’t work for automatic transmissions. I personally check the battery terminals every six months to ensure they’re tight and clean any oxidation points. Learning some basic car knowledge saves money and is efficient—don’t delay too long to avoid damaging engine components.
