How to Jumpstart a BMW

BMW X7 in Front of House

BMW vehicles often have their batteries located in the trunk, behind a small panel that’s easy to identify and remove. Once you’re aware of this important difference, learning how to jumpstart a BMW is far from difficult. In fact, if you already know how to jumpstart a car, locating the battery is the only real challenge in your way! Just check your owner’s manual if you’re unsure, or give us a call at (952) 213-5577 to get the answer you need today.Once you’ve found your BMW battery, you can simply follow the steps laid out below and get back on the roads of St Paul or Minneapolis.

How to Jumpstart a Car the Smart Way

Caution is of the utmost importance when you’re working with a high-powered and dangerous car battery. Although jumpstarting a BMW isn’t as dangerous as installing a new battery, it’s a good idea to review the safety precautions in our guide to BMW battery removal before you get started. The only other thing you’ll need to get started is a set of jumper cables! We should also point out that, whether you’re learning how to jumpstart a BMW 328i or a BMW SUV, there’s no difference in the type of jumper cables you’ll need to buy! Any standard set will do just fine.

How Do You Jumpstart a Car with a Rear Battery?

Once you have your jumper cables, call a friend or ask another nearby driver if they’re able to help! They’ll need to pull their vehicle up to yours so you can connect the batteries. They should be close enough so that the cables have a little bit of slack, but not so close that the vehicles are touching one another. Now that both models are in position, here’s how to jumpstart a BMW:

  1. Remove the covering from both batteries and identify the positive and negative terminals on each.
  2. Attach the first red clamp to your BMW vehicle’s red (positive/+) terminal.
  3. Hook up the second red clamp to the positive terminal on the working battery.
  4. Next, attach one of the black clamps to the black (negative/-) terminal on the working battery.
  5. Attach the last black clamp to any unpainted metal surface on your vehicle.

Work exactly in the order we’ve laid out above, and when you remove the cables, make sure to proceed in reverse! Don’t let the clamps touch one another during the process, as this can create sparks which may result in fire.

How to Jumpstart a BMW: Charging the Battery

The vehicle with the working battery can now fire up their engine. As it runs, the vehicle with the dead battery will receive the charge. You should wait at least a few minutes before you get into your own vehicle and try to start the engine. After your engine is able to get started, carefully remove the jumper cables according to the guidelines identified above. After disconnection, don’t turn off your vehicle right away! It’s a good idea to drive for at least 30 minutes after a jump start, so the alternator has time to recharge the battery and you won’t be left stranded again.
