Gauges
Temperature Gauge
This shows the temperature of the
engine's coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (hot) mark, pull
safely to the side of the road. For
instructions and precautions on
checking the engine's cooling
system, see page 286 .

Outside Temperature Indicator
If equipped
This indicator displays the outside
temperature in Fahrenheit (U.S.
models) or Centigrade (Canadian
models).
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 indicator
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 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
indicator, make sure the outside
temperature indicator is shown in
the display, then press and hold the
RESET button for 10 seconds (the
TRIP A or B is also reset). The
following sequence will appear for 1
second each: 0, 1, 2, 3, 4, 5,
3, 2, 1, 0 (U.S.) or 0, 1, 2, 3,
3, 2, 1, 0 (Canada).
When it reaches the desired value,
release the 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.
