Open the cover of the positive terminal by simply pulling it up.
To jump-start, connect the red jumper cable to the positive terminal of the battery and connect the black jumper cable to the frame of the vehicle.For example, strut tower bolt.
Connect the jumper cables to the battery of the support vehicle. Ensure that the positive cable is connected to the positive terminal and the negative cable is connected to the negative/ground terminal.
Before starting the vehicle, wait for a few minutes for the battery to recharge, then start the engine.

Charge the battery fully then test it with a battery tester. For more help follow this guide. Check the battery date sticker on the top or side of battery. Most car batteries last between three to five years.
During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion. Particularly avoid fire, open flames, creating sparks, and smoking. Ensure there is sufficient ventilation while charging and jump-starting. Do not lean over a battery.

How to get into the trunk, if you have a dead battery

Use the emergency key blade found inside your key fob to manually unlock the trunk.

How to charge a dead battery

By trickle charging a dead battery, you have a better chance of bringing the battery back to life. Otherwise, your battery may no longer hold a proper charge.
Use the OEM 12 Volt Battery Charger or even the cheaper Black+Decker BBM3B 12V Battery Charger Maintainer, which works just as well.
It will take at least 24 hours to bring a completely dead battery back to life. You are only providing 2 Amperes to the battery, which is a slow charge but ensures no damage is caused to the battery cells.

My car battery keeps dying

If your battery keeps on dying or is not holding a proper charge, it could be due to any of the following:
- Battery age / old battery
- Corroded or loose battery connections
- Parasitic current drains in the electrical system.
