Compass / Temperature Display - Jeep Grand Cherokee 2013 Operating Information Manual

Compass / Temperature Display

The compass readings indicate the direction the
vehicle is facing. The EVIC will display one of
eight compass readings and the outside tem-
perature.
NOTE:
The system will display the last known out-
side temperature when starting the vehicle
and may need to be driven several minutes
before the updated temperature is dis-
played. Engine temperature can also affect
the displayed temperature; therefore, tem-
perature readings are not updated when the
vehicle is not moving.

Automatic Compass Calibration
This compass is self-calibrating, which elimi-
nates the need to manually reset the compass.
When the vehicle is new, the compass may
appear erratic and the EVIC will display CAL
until the compass is calibrated. You may also
calibrate the compass by completing one or
more 360–degree turns (in an area free from
large metal or metallic objects) until the CAL
indicator displayed in the EVIC turns off. The
compass will now function normally.
NOTE:
A good calibration requires a level surface
and an environment free from large metallic
objects such as buildings, bridges, under-
ground cables, railroad tracks, etc.
Compass Variance
Compass Variance is the difference between
Magnetic North and Geographic North. To com-
pensate for the differences the variance should
be set for the zone where the vehicle is driven,
per the zone map. Once properly set, the com-
pass will automatically compensate for the dif-
ferences, and provide the most accurate com-
pass heading. For the most accurate compass
performance, the compass must be set using
the following steps.
NOTE:
Keep magnetic materials away from the top
of the instrument panel, such as iPod's,
Mobile Phones, Laptops and Radar Detec-
tors. This is where the compass module is
located, and it can cause interference with
the compass sensor, and it may give false
readings.
