PRELIMINARY CHECK FOR THERMOMETER
NOTE: The indicated temperature on the thermometer is not readily affected by engine heat. It changes only when one of the following conditions is
present.
The temperature detected by the ambient air temperature sensor is lower than the indicated temperature on the thermometer.
The vehicle speed is greater than 20 km/h (13 MPH).
(This is to prevent the indicated temperature from being affected by engine heat during low-speed driving.)
The ignition switch has been turned to the OFF position for more than 2 hours. (The engine is cold.)
