Jeep 2011 Wrangler - Manual (Page 286)

ECO (Fuel Saver Indicator) — If Equipped
The ECO-ON indicator will illuminate when you are
driving in a fuel efficient manner and can be used to
modify driving habits in order to increase fuel economy.
The ECO display will toggle between ECO and ECO-ON
depending on driving habits and vehicle usage.
Compass/Temperature Display
NOTE: If the vehicle is equipped with a Chrysler
Uconnect™ gps (Navigation Radio), the NAV system will
provide the compass direction, and the variance and
calibration menus will be unavailable. The compass will
perform accurately, based on GPS signals instead of the
Earth’s magnetic field.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences and provide the most accurate compass head-
ing.
NOTE:
• A good calibration requires a level surface and an
environment free from large metallic objects such as
buildings, bridges, underground cables, railroad
tracks, etc.
• Magnetic materials should be kept away from the top
of the center of the instrument panel. This is where the
compass sensor is located.
