The 12-volt battery is located in the trunk, on the passenger side, beneath the floor panel.
In the 2017 Audi A5, Audi placed the 12V battery in the luggage area rather than under the hood to optimize space and weight distribution. Access is gained by lifting the trunk floor carpet and removing a small cover that hides the battery, which sits in a protective case near the right-rear corner of the cargo area. While exact panel placement can vary slightly by trim, the battery is traditionally found in the trunk on the passenger side.
Locating the battery in the trunk
Use this quick guide to confirm the battery's location and what you’ll encounter when you open the trunk floor.
- Location: in the trunk on the passenger-side area, beneath the floor panel.
- Access: remove the trunk floor carpet and lift the small plastic cover or panel that hides the battery.
- Observation: the battery sits in a protective plastic case, often with a red positive terminal cover and a visible negative terminal opposite it.
With the trunk floor opened and the panel removed, you should clearly see the battery housing and be able to proceed with inspection, jump-start, or replacement as needed. Always exercise caution and follow the owner’s manual for specific instructions and safety recommendations.
Safe steps for access, jump-starts, and maintenance
Before handling the battery, follow these steps to reduce risk and avoid damage.
- Park on a level surface, engage the parking brake, and ensure the ignition is off with the key removed from the ignition.
- Open the trunk and locate the battery on the passenger side under the floor panel; remove the floor panel and plastic cover to expose the terminals.
- Disconnect the negative (-) terminal first, then the positive (+) terminal to prevent short circuits.
- If jump-starting, connect the red clamp to the positive terminal of the donor vehicle and then to the positive terminal of the A5 battery, and connect the black clamp to a solid ground point on the donor vehicle or to the A5’s negative terminal last. Do not attach the black clamp to the engine block if not recommended in the manual.
- After the A5 starts, remove the clamps in reverse order, then reassemble the battery cover and trunk floor panel.
These steps cover basic safety for accessing and working with the trunk-mounted battery in a 2017 A5. If the battery repeatedly discharges or you notice corrosion, have it inspected or replaced by a certified technician.
Notes on variations and professional guidance
Some configurations or regional markets may include auxiliary batteries or different battery management setups. If you encounter unfamiliar components or unusual paneling, consult the owner’s manual or contact a dealer for model-specific guidance.
