- The temperature range that can be displayed is from -40°F (-40°C) to 122°F (50°C).
- Vehicles with monochrome display When the outside temperature drops below 37°F (3°C), the temperature display flashes 10 times.
- Vehicles with color display When the outside temperature drops below 37°F (3°C), the ICE warning indicator will be displayed on the multi-information display.

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 completely.
