Dodge 2009 Ram 3500 - Manual (Page 153)

WARNING!
Even if the display still reads a few degrees above
32°F ( 0°C), the road surface may be icy, particularly
in woods or on bridges. Drive carefully under such
conditions to prevent an accident and possible per-
sonal injury or property damage.
Automatic Compass Calibration
This compass is self-calibrating which eliminates the
need to manually set the compass. When the vehicle is
new, the compass may appear erratic and the CAL
symbol will be displayed.
After completing up to three 360 degree turns, with the
vehicle traveling less than 5 mph (8 km/h), in an area free
from large metal or metallic objects, the CAL symbol will
turn off and the compass will function normally.
Manual Compass Calibration
NOTE: To ensure proper compass calibration, make
sure the compass variance is properly set before manu-
ally calibrating the compass.
If the compass appears erratic and the CAL symbol does
not appear, you must manually put the compass into the
“Calibration” mode.
Recalibrating The Compass
Start the engine and leave the transmission in the PARK
position then set the display to “Compass/Temperature.”
Press and hold the RESET button to change the display
between VAR (compass variance) and CAL (compass
calibration) modes. When the CAL symbol is displayed,
complete one 360 degree turn in an area free from large
metal objects or power lines. The CAL symbol will turn
off and the compass will function normally.
