Outside Temperature Indicator
This indicator displays the outside
temperature in Fahrenheit (U.S.
models) or Centigrade (Canadian
models). To see the outside
temperature, press and release the
SEL/RESET button until the
temperature is shown on the
information display.
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.
Gauges
If the outside temperature is
incorrectly displayed, you can adjust
it up to 5°F ( 3°C) warmer or
cooler.
NOTE: The temperature must be
stabilized before doing this
procedure.
Select the outside temperature
display, then press the SEL/RESET
button for 10 seconds. The following
sequence will appear for 1 second
each: 0, 1, 2, 3, 4, 5, 5, 4,
1, 0 (U.S.) or 0, 1, 2, 3, 3,
1, 0 (Canada).
When it reaches the desired value,
release the SEL/RESET button. 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.
