To display the screen in the day mode even with the headlight switch on, touch "DAY MODE" on the adjustment screen for brightness and contrast control. However, if the switching km/h MPH button is on, mode switching cannot be done. It remains in the day mode. In this case, "DAY MODE" is not shown on the screen. If the screen is set in the day mode with the headlight switch turned to on, this condition is memorized in the system even with the hybrid system turned off. The outside temperature is shown ranging from -30_C (-22_F) up to 50_C (122_F) at the upper right of the energy consumption or energy monitor screen. If the warning light symbol is shown in that position, the outside temperature is not displayed until the cause of the system failure is eliminated. 118
