• When the duration of ignition switch OFF to ON is long.
The last indicated temperature is displayed when the vehicle enters in either of the following conditions.
• When the detected temperature by ambient sensor is lower than the indicated temperature on information

display.

• When the duration of ignition switch OFF to ON is short.

Correction Process (When the ignition switch is ON)

The detected temperature by ambient sensor is displayed under the following condition.
• When the detected temperature is lower than the indicated temperature on information display.
The indicated temperature is not updated under the following condition.
• When the detected temperature by ambient sensor is higher than the indicated temperature on information

display [at a speed of 20 km/h (12 MPH) or less].

The indicated temperature on information display rises slowly to reach the detected temperature by ambient
sensor under the following condition.
• When the detected temperature is higher than the indicated temperature on information display [at a speed

of more than 20 km/h (12 MPH)].

The indicated temperature on information display rises to reach the detected temperature by ambient sensor
under the following condition.
• When the detected temperature is higher than the indicated temperature on information display [while driv-

ing a certain period of time at a speed of more than 20 km/h (12 MPH)].

NOTE:
• “

−−−−

” is displayed for 2.5 seconds right after ignition switch is turned ON.

• If a battery or combination meter is removed and installed, the detected temperature by ambient sensor is

displayed, right after ignition switch is turned ON.

• The indicated temperature may be higher than the actual temperature because of heat radiation from engine

or reflection of heat on road surface.
