The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display 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 cau se the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in personal
death or injury.
NOTICE ■
To prevent damage to the engine and its components ●
When the tachometer is displayed, 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); or “Engine Coolant Temp High” or “Hybrid System Overheated” is shown
on the multi-information display. In this case, immediately stop the vehicle in a safe
place, and check the engine or hybrid system after it has cooled completely.
