Trouble Diagnosis For Symptoms
Inspection/Compass And Thermometer
NOTE: When the outside temperature is between 55 °C (130 °F) and 70 °C (158 °F), the display shows 55 °C (130 °F). When the outside temperature
is lower than 30 °C ( 20 °F) or higher than 70 °C (158 °F), the display shows only "---".
The indicated temperature on the thermometer is not readily affected by engine heat. It changes only when one of the following conditions is
present.
a. The temperature detected by the ambient air temperature sensor is lower than the indicated temperature on the thermometer.
b. The difference in temperature detected during a period of 40 seconds is less than 1 °C (1.8 °F) when vehicle speed has been greater than
24 km/h (15 MPH) for more than 100 seconds.
(This is to prevent the indicated temperature from being affected by engine heat or cooling fan operation during low-speed driving.)
c. The ignition key has been turned to the "OFF" position for more than 4 hours. (The engine is cold.)
