NOTE
This thermometer indicates the ambient temperature in back of front bumper. Under any one of the 
following listed conditions, however, even when the ambient temperature goes up, the thermometer 
display does not rise so as to correct the rise of the ambient temperature caused by the radiant heat of 
the engine. When the ambient temperature drops, the thermometer reading follows the change in the 
temperature.
Be sure to bear this in mind when diagnosing trouble.
• The vehicle speed is 30 km/h (18 mph) or lower.
• Vehicle speed signal is faulty.
• The ignition switch is turned on again within 2 hours.
