Compass Temperature Display
This display provides the outside temperature and one of
eight compass readings to indicate the direction the
vehicle is facing.
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.
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 [16 kmh]) 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.
