Do You Know How to Jump-Start Your Car in Cold Weather?
At Baron BMW, we're all too aware of what winter brings: frozen pipes, bitterly-cold temperatures and dead batteries. If you should be unlucky enough to find that your ride is unresponsive, here are some steps to take:
Park the car helping you 18 inches away from your vehicle, facing nose-to-nose. Put both vehicles in park, set the emergency brakes and turn off the engines.
Start with the red cable. Connect one end to the dead battery's positive terminal, and then the other to the helping car's positive terminal. Then clamp one end of the black cable to the negative terminal on the working car's battery and the other end to a metal section in the car with the dead battery.
Start the working car, slightly revving the engine and letting it run for a couple of minutes. When you attempt to start the vehicle with the dead battery, limit your attempts to no more than four times in a row – any more and you could damage the vehicle's electrical system.
Disconnect the cables once the dead vehicle is running. Always remove them in reverse order of the way you connected them, making sure that the clamps don't touch.
Take a drive to let the battery recharge to full capacity. If you're concerned about the long-term life of your battery, the expert technicians at our Service Center will be more than happy to ensure that it's in proper running order.
