(OUTSIDE TEMPº)
The outside temperature display indi-
cates the outside air temperature.
The displayed temperature ranges from
-22F (- 30C) up to 122F (50C).
If an abnormality exists in the connection
of the outside air temperature sensor,
- -Fº (- -Cº) will appear on the display.
If - -Fº (- -Cº) appears on the display,
contact your Toyota dealer.
There may be a case that - -Fº (- -Cº)
appears momentarily when the ignition is
quickly turned to ONº. It is normal if it
goes out soon.
2. Average vehicle speed
(AVG MPHº or AVG km/hº)
Average vehicle speed is calculated and
displayed based on total driving dis-
tance and total driving time with the
engine running.
The displayed value is updated every 10
