Locate The Battery
Jump starting your BMW E90 requires you to locate the battery first. Knowing the battery’s location is essential for a successful jump start. Follow these steps to find and access the battery easily.
Identify Battery Location
The BMW E90 battery is not under the hood. It is in the trunk. This unique location can be confusing for many drivers. Open the trunk to find it.
Access Battery Compartment
Once the trunk is open, look for a small cover on the right side. Remove this cover to reveal the battery compartment. You may need a screwdriver to remove the cover. Gently lift the cover to avoid damage.
Now, you can see the battery and its terminals. Ensure the battery connections are clean and free from corrosion. You are now ready to proceed with the jump start process.

Before jump-starting your BMW E90, it’s essential to position the cars correctly. This step is crucial for safety and efficiency. Follow these guidelines to ensure proper positioning.
Align Vehicles Correctly
First, park the donor car close to your BMW E90. Make sure the front ends of both cars are facing each other. Keep a small distance to avoid contact. This allows the jumper cables to reach both batteries easily.
Ensure Parking Brake Is Engaged
Next, engage the parking brake on both vehicles. This prevents any unwanted movement. It’s a vital safety measure while working under the hood. Double-check that both cars are in “Park” or “Neutral” mode.

Connect Jumper Cables
Jump starting your BMW E90 requires proper steps to avoid damage. One important step is connecting the jumper cables correctly. This section will guide you on how to connect the jumper cables effectively.
Attach Positive Cable
First, locate the positive terminals on both cars. The positive terminal usually has a red cover or a “+” symbol. Open the hood of your BMW E90 and the other car. Attach one end of the red cable to the positive terminal of the dead battery. Then, attach the other end of the red cable to the positive terminal of the working battery.
Attach Negative Cable
Next, locate the negative terminals. The negative terminal usually has a black cover or a “-” symbol. Attach one end of the black cable to the negative terminal of the working battery. Now, attach the other end of the black cable to a metal part of your BMW E90. This part should be unpainted and away from the battery. It helps to prevent sparks.
By following these steps, your BMW E90 will be ready to start. Always double-check the connections before attempting to start the car. Proper connection of jumper cables ensures safety and efficiency.
Start The Donor Car
Starting the donor car involves connecting the jumper cables to the BMW E90’s battery terminals. Make sure the cables are securely attached to avoid sparks. Start the donor car and let it run for a few minutes to charge the dead battery.
Jump-starting your BMW E90 begins with the donor car. This is the vehicle whose battery will help power your car’s dead battery. Make sure the donor car has a functioning battery. Both cars should be parked close together but not touching. Ensure both cars are off and the keys are out of the ignition.Ignite The Donor Engine
Now, sit in the donor car’s driver seat. Insert the key into the ignition. Turn the key to start the engine. Let the engine run. This will provide the necessary power to jump-start your BMW E90.Let It Run For A Few Minutes
After starting the donor car, let it run for a few minutes. This helps the battery charge up. Keep the donor car running while you prepare to connect the jumper cables. The extra power will make it easier to start your BMW E90. Stay patient. This is a crucial step. “`

| Step | Action |
|---|---|
| 1 | Locate the negative terminal |
| 2 | Loosen the nut with a wrench |
| 3 | Remove the negative cable carefully |
| 4 | Locate the positive terminal |
| 5 | Loosen the nut with a wrench |
| 6 | Remove the positive cable carefully |
Following these steps will help you safely remove the cables from your BMW E90. Always remember to handle the cables and terminals with care to avoid any potential hazards.
Post-jump Procedures
