Battery Every new Aurora has a Delco Freedom@battery. You never have to add water to one of these. When it's time for a new battery, we recommend a Delco Freedom@ battery. Get one that has the replacement number shown on the original battery's label. The battery is located under the rear seat cushion. To access the battery, see "Removing the Rear Seat Cushion" in the Index. You don't need toaccess the battery to jump start your vehicle. See "Jump Starting" in the Index. CAUTION: - A battery that isn't properly vented canlet sulfuric acid fumes into the area under the rear seat cushion. These fumes can damage your rear seat safetybelt systems. You may not be able to see this damage, and the safety belts might not provide the protection needed in crash. If a a replacement battery is ever needed, it must be vented in the same manner as the original battery. Always make sure that the hose vent is properly reattached before reinstalling the seat cushion.
