Compass Calibration
The compass on your vehicle will automatically calibrate
when new, and will continuously adjust itself over the
life of the vehicle. If the CAL indicator is on (or flashing),
drive slowly (under 10 MPH) in an open area until the
CAL indicator is off.

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 and battery powered devices, (such as cell

phones, iPod’s, radar detectors, PDA’s and laptops)
should be kept away from the top of the instrument
panel. This is where the compass module is located
and such devices may interfere and cause false com-
pass readings.

Automatic Compass Calibration
The self-calibrating feature of the compass eliminates the
need to calibrate the compass for normal conditions.
During a short initial period, the compass may appear
erratic and the CAL symbol will appear (blinking) on the
display. After the vehicle has completed at least one
complete circle under 5 mph (8 km/h) in an area free
from large metal objects, calibration will be complete
when the CAL symbol is extinguished.

After initial calibration, the compass will continue to
automatically update this calibration whenever the ve-
hicle is in motion.

Manual Compass Calibration

NOTE:

Before attempting a manual compass calibra-

tion, the engine must be running and the transmission
in the PARK position (if equipped).
