Outside Ambient Air Temperature
The following is required to display the outside ambient air temperature:
- Outside air temperature
- Wheel speed signal
- Engine run time
- Engine coolant temperature
The outside ambient air temperature is determined by the outside ambient air temperature sensor. The temperature sensor is installed at the front left of the vehicle under the bumper fascia and is connected to the Instrument Cluster. The wheel speed signal, engine run time, and engine coolant temperature are determined internally by the Instrument Cluster. Since the outside ambient air temperature display depends on the wheel speed, engine run time, and engine coolant temperature, the temperatures are not updated when the vehicle is stationary or moving slowly.
The following is the vehicle criteria necessary for determining outside air temperature:
- When the ignition is in the ON position and the engine coolant temperature < 60°C (140°F), the current air temperature is always stored and displayed.
- When the ignition is in the OFF position and the engine coolant temperature < 60°C (140°F), the air temperature last measured is stored and displayed.
- When the ignition is in the ON position and the engine coolant temperature < 60°C (140°F), the stored air temperature is displayed.
- At vehicle speeds of 19-60 km/h (12-37 MPH), outside air temperatures are displayed after a delay of approximately 5 minutes.
- At vehicle speeds over 60 km/h (37 MPH), outside air temperatures are displayed after a delay of approximately 2 minutes.
