The temperature sensor is in the
front bumper. Therefore, the
temperature reading can be affected
by heat reflection from the road
surface, engine heat, and the
exhaust from surrounding traffic.
This can cause an incorrect
temperature reading when your
speed is under 19 mph (30 km/h).
The sensor delays the display update
until it reaches the correct outside
temperature. This may take several
minutes.
If the outside temperature is
incorrectly displayed, you can adjust
it up to 5°F in U.S. models ( 3°C
in Canadian models) warmer or
cooler.
NOTE: The temperature must be
stabilized before doing this
procedure.

To adjust the outside temperature
display, press and hold the Select/
Reset knob for 10 seconds. The
display changes as shown above.
Select the outside temperature
indicator by turning the Select/Reset
knob. The display begins to blink,
push the same knob to enter this
setting, then turn it to adjust the
temperature. The following
sequence will appear for each: 0, 1, 2,
3, 4, 5, 5, 4, 3, 2, 1, 0 (U.S.)
or 0, 1, 2, 3, 3, 2, 1, 0 (Canada).
When it reaches the desired value,
push the Select/Reset knob to enter
the setting. You should see the new
outside temperature displayed.
In certain weather conditions,
temperature readings near freezing
(32°F, 0°C) could mean that ice is
forming on the road surface.
