1.	Outside Air Temperature Indicator - Calibration

Description

The outside temperature sensor is located behind the middle of the front bumper. The gauge control module uses measurements from this sensor to display the outside air temperature.
Because of the location of the sensor, it may be affected by heat reflection from the road, engine and radiator heat, or hot exhaust from surrounding traffic.
These conditions can soak the outside air temperature sensor in heat and cause inaccurate readings. Logic has been written into the multi-information display to help prevent abnormal or fluctuating outside air temperature indicator readings.

Outside Air Temperature Indicator Logic

Initial outside air temperature is indicated after the ignition switch is turned ON (II):

If the engine coolant temperature is 140°F (60 °C) or higher when the ignition switch is turned ON (II), the outside air temperature indicated the last time the key was turned off will be displayed regardless of the current temperature measured by the outside air temperature sensor.

If the engine coolant temperature is 138°F (59 °C) or lower when the ignition switch is turned ON (II), the current temperature measured by the outside air temperature sensor will be indicated.

Troubleshooting

If the indicator displays ---°F for more than 2 seconds after selecting the outside air temperature display mode, check the outside air temperature sensor or the multi-information display (MID).

Calibration

NOTE: The outside air temperature indicator's displayed temperature can be recalibrated 5 °F (3 °C) to meet the customer's expectations.

Turn the ignition switch to ON (II).

To enter the customized setting display, select the above display with the MENU button, then press the SOURCE button customizing mode.

While in the customizing mode, select the "Trip Computer Setup". Then select the "Adjust Outside Temp. Display", and calibrate the value with the MENU button and the SOURCE button.

name

When the desired correction value appears on the display, release the button, and the recalibrated outside air temperature will be displayed.

NOTE: The recalibration temperature is not the value the sensor detects. Therefore, the temperature can only be adjusted 5 °F (3 °C) from what the sensors display.

Example:
Incorrect value	= 68 °F (20 °C)

Desired correction value	= +2 °F (+1 °C)
Correct value	= 70 °F (21 °C)

Desired correction value	= -2 °F (-1 °C)
Correct value	= 66 °F (19 °C)

NOTE: To recalibrate the display to the true temperature, remove the outside air temperature sensor (A), but leave it connected. Submerge the sensor and a thermometer (B) in a container of ice water (C). Select the calibration mode as described above, then recalibrate the display to the true temperature.

The snow mark is displayed when the temperature is 5 °F (3 °C) or less the first time the ignition switch is turned back ON (II).
