Service information like tire pressure (shown here on the Pebble watch), fuel level, check engine light, oil warning, and coolant levels can also be detected.
Watches aren't the only devices that will be able to pair with the new Mercedes vehicles. Google Glass integration is also in the works. Door-to-door navigation is a program that will direct drivers to their cars via pedestrian routing with CarFinder, and then Glass will pass the destination to the in-vehicle navigation system automatically. After parking, Google Glass will take over navigation with pedestrian navigation once again.
