■Outside temperature display
●In the following situations, the correct
outside temperature may not be dis- played, or the display may take longer than normal to change:
• When stopped, or driving at low speeds (less than 25 km/h [16 mph])• When the outside temperature has
changed suddenly (at the entrance/exit of a garage, tunnel, etc.)
●When “--” is displayed, the system may be malfunctioning. Take your

■Customization
The gauges and meters can be custom-
ized in of the multi-information dis-

■Changing the display
Press the display change button
until the desired item is displayed.
WARNING
■The information display at low temperatures
Allow the interior of the vehicle to
warm up before using the liquid crys- tal information display. At extremely low temperatures, the information dis-
play monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between
the driver’s shifting and the new gear number appearing on the display. This lag could cause the driver to
downshift again, causing rapid and excessive engine braking and possi-bly an accident resulting in death or
injury.
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indicates the maximum
engine speed.
●The engine may be overheating if
the engine coolant temperature gauge is in the red zone (H). In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled com-pletely. ( →P.346)
