Understand the Basics of Jumpstarting
What is Jumpstarting?
Jumpstarting is a process where you use another vehicle’s battery to start your car when your own car battery has died. One of the reasons why jumpstarting works is that it only requires a short burst of electrical energy from one car battery to the other, helping to jump-start your dead battery.
Why is Jumpstarting Necessary?
There are several possible reasons for requiring a jumpstart; perhaps you left the interior lights on overnight or you have an old battery that won’t hold a charge anymore. Whatever the reason, having a way to get your engine going can save you money and time in getting your vehicle back on the road. As long as you know how to jumpstart correctly, you will be in good hands with this essential skill.
When Should You Jumpstart Your Car?
If your BMW car’s battery has run down, you might need to jumpstart it right away. If your car doesn’t start at all or starts sluggishly, then you should not wait any longer before attempting a jumpstart. It would help if you also kept an eye out for signs like dimming headlights, slow wipers, or dashboard warning lights because these could also indicate that your battery is failing and needs replacement.
How to Safely Jumpstart a Car?
Jumpstarting your car may seem like a straightforward task, but there are some safety precautions that you must follow when dealing with such high voltage electricity. The following steps highlight how to safely jumpstart your BMW:
- Park both cars close enough so that their batteries are within reach of each other.
- Make sure that both cars are turned off and their parking brakes are engaged.
- Open the hood of both cars and locate the batteries.
- Identify the positive (+) and negative (-) terminals on each battery. Attach the red (positive) cable clamp to the BMW’s dead battery’s positive terminal and then attach its other end to the donor car’s positive terminal.
- Now attach the black (negative) cable clamp to the donor car’s negative terminal, followed by attaching its other end to an unpainted metal surface near your dead car but away from the battery itself. This step is important because you want to ground the circuit without the risk of an explosion due to gases emitted from the battery.
- Turn on the donor vehicle’s engine and let it run for a few minutes
- Try starting up your BMW. If it doesn’t start, wait a bit longer before attempting another try or consider seeking help from a professional mechanic.
- Once your BMW starts successfully, immediately disconnect the jumper cables in the reverse order from which they were attached.
“Always remember that jumpstarting can be dangerous if done incorrectly. Remember to wear safety gear like gloves and eye protection, never touch the clamps with your bare hands or allow them to come into contact with each other when they’re connected. And always turn off all gadgets and electrical stuff inside the cars during this process. “-Auto.com
Knowing how to jumpstart a car battery is an essential skill every driver needs to have. Even though it may seem daunting at first, following these simple steps can ensure that you safely get your car back to working order when stranded on the road with a dead battery.

Identify the Right Tools Needed
If you drive a BMW, it is essential to know how to jumpstart your car, especially during an emergency. Jumpstarting a car requires specific tools and accessories that you need to have readily available when needed.
What Tools Do You Need to Jumpstart a Car?
Jumpstarting a BMW requires just a few tools, which include:
- A set of jumper cables with sturdy alligator clamps on each end.
- An additional vehicle or portable jump starter pack with enough power to provide a robust boost of electricity to your dead battery.
- Gloves and safety glasses- Gloves for added protection against electrical shock from sparking. Safety glasses protect your eyes from potential explosions in the event of an accident.
The purpose of these tools is to transfer power from a good running vehicle through the jumper cables and into the dead battery. The additional vehicle acts as a temporary charging station to recharge the flat battery. Ensure the gauge size of the jumper cables is at least 4-6 gauge to supply sufficient power to start the engine. Anything lower may not deliver enough voltage across the cable for an effective charge.
Where Can You Find the Right Tools?
You can purchase jumper cables at most automotive shops, tire centers or big-box store. Always verify if they meet industry-standard amp ratings before making any transactions. This way, you protect yourself from buying low-quality jumper cables less vulnerable to failure.
Your local automobile repair shop may also be another place you could source this equipment. When choosing this option, ensure you buy genuine parts for long-lasting service.
Caring for your equipment is critical for ensuring its longevity. Avoid exposure to moisture by cleaning after each use and storing in a safe, dry place.
“The last thing you want is to be stranded without the right jumpstart tools. Keep essential equipment handy for those emergency situations,” says John Garcia, an auto repair expert.
Locate the Battery and Connect the Jumper Cables
How to Find the Battery in Your Car?
The battery of your BMW is usually located in the engine compartment, but it can also be found under the trunk floor or in the rear of the vehicle. Once you pop open the hood of your car, take a few moments to locate the battery. It’s a rectangular box with one negative (-) and one positive (+) terminal on top.
If necessary, consult your owner’s manual for guidance on where to find the battery. Some models might have additional compartments or covers that need to be removed before you can access the battery.
Steps to Connect the Jumper Cables Safely?
Jumpstarting a BMW requires caution and careful attention to detail to avoid damaging your vehicle. Here are some steps to follow:
- Park both cars close together, turn off the engines, and engage the parking brakes.
- Take out the jumper cables from the carrying case and identify the positive (red) and negative (black) clamps.
- Attach the red clamp to the positive terminal on the dead battery and then attach the other end of the red clamp to the positive terminal of the auxiliary battery.
- Next, attach the black clamp to the negative terminal on the working battery.
- BUT DO NOT connect the black clamp directly to the negative terminal of the dead battery! Instead, connect the other end of the black cable to an unpainted metal surface like the transmission bell housing or an engine bracket on the disabled car.
- Start the engine of the assisting vehicle and let it run for a few minutes.
- Turn the key in the ignition of the dead car to start the engine. The vehicle should start within seconds or a few minutes.The longer it takes for the car to start, the more time and power it requires.
- Remove the jumper cables in reverse order (black from the disabled car, black from the assisting car, red from the assisting car and red from the dead battery).
“It’s better to be cautious than reckless when jumpstarting your car. A small mistake can cause significant damage to your electrical system”. -Mike Miller, Car expert at BMW Blog
Remember, if you’re unsure about any part of this process seek advice from a qualified mechanic or roadside assistance service. Jumping batteries can lead to injury, fires, and other hazards that are best avoided by professionals with specialized tools and experience.
If your car still doesn’t start after following these steps, don’t try again right away. Several attempts can overheat and damage the starter motor. Instead, have a tow truck take your car to an auto repair shop for proper diagnosis and repair.
