The Nautilus has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced.

The Nautilus’ rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The QX50’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.
