Precaution for Battery Service
WARNING: This page is about a different car, the 2011 Infiniti G37. However, it is still accessible from the selected car via links, so may be relevant.
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.
