In this guide, you will learn how to jump-start your BMW 3-Series. This is applicable to BMW years 2004-2013.
Turn off ignition
Remove key from the ignition. BMWs are very sensitive to voltage and BMW 3-Series is no exception. To avoid electrical problems, start by removing the key from the ignition.
Open the hood. Locate the hood release underneath the dash. Pull the lever until you hear the hood pop open. Next, you need to release the hood safety latch at the front of the hood.
Locate the terminals where you can jump start your BMW 3-Series. They are on the passenger side of the engine.
Attach the red (positive) cable to the positive jump start terminal. If you are using another car to jump start your BMW 3-Series, you will connect the red clamp here.
Connect Negative Cable
Connect the black (negative) cable to the ground post which is the negative terminal.
If you are using a jump box you are now ready to start your BMW. If you are using jumper cables to start the car, continue to the next step.
