Remove the emergency key from the key fob and use it to unlock the driver's door. If the keyhole in the driver's door handle is covered, use the emergency key to pry out the cover and expose the key tumbler.
Turn off the ignition. Remove the key from the ignition to avoid electrical issues.
Pull the hood release under the dashboard and open the hood.
The battery is located on the driver's side, as shown in the picture below.
Lift the cover from the positive battery post to expose the terminal.
Attach the red (+) cable to the positive terminal. If you are using another car, connect the other red clamp (the other end of the jumper cable) to the helper car's positive terminal.
Connect the black (negative) cable to the frame. For example, the bolts for the struts work well for this. Be cautious when connecting directly to the negative terminal.
If using a helper car, connect the other end of the jumper cables to the other vehicle. Start the helper vehicle and let it idle.
Get inside your Nissan with the dead battery and start the engine. If your Nissan dashboard powers up, you hear a clicking noise check to make sure the clams are making good contact. Also, allow your battery to charge for a few minutes and try again.
Keep the key out of the ignition and the ignition off until you are ready to start the engine.
During this procedure, you should be extremely careful not to allow the red and back clamps to make contact.
