Outside Air Temperature
If the outside temperature falls below 3.3°C (38°F), the display will alternate from "ICE" to the outside temperature at a two second rate for one
minute.
The outside air temperature reading can be affected by engine heat when the vehicle is idling or has been off for less than two hours. The compass
and outside temperature will limit the increase of the displayed temperature to one degree per minute at very low speeds or immediately after the
ignition is turned on. After two minutes at a sustained speed of at least 53 km/h (33 mph), effects of engine heat are minimal and the compass will
display the current outside temperature reading. Temperature decreases are always updated immediately.
If the outside air temperature sensor is short or open circuited, then the display will show 60°C (140°F) or -40°C (-40°F) respectively in place of
temperature.
Average (AVG) Fuel Economy-Resetting
NOTE: Only the AVG fuel economy can be reset. The DTE display cannot be reset.
The AVG fuel economy display is resettable. To reset, the ignition switch must be in the RUN position (with or without the engine running) and the
message center must be in the AVG fuel economy mode.
Depress and hold both buttons while in AVG fuel economy mode for a period of two to three seconds until AVG is displayed. Release both buttons
to reset AVG fuel economy.
If the vehicle is parked while resetting, the AVG fuel economy will display 99.9 (metric mode) or 0.0 (English mode).
