Service Information

Using this menu, the driver can enable, disable, and set service intervals for engine miles or engine hours. After enabling service intervals, select interval unit (miles or hours), and the interval duration.

Settings

The settings menu contains the controls for the following settings:

• Display (includes brightness, contrast, display light, and night mode settings)

• Gauge select

• Language

• Time zone

• Self-test

The ICU4Me control switch can also be used to uncheck boxes if necessary.

Using the Time Zone submenu, the driver can select supported time zone. Use the + and – switches to increment between time zones, see Fig. and see Fig..

Once the operator has selected the time zone, the operator will be able to enable or disable the Daylight Savings, see Fig.. When the Daylight Savings is ‘ON’, a pop-up confirmation screen shall confirm the time by displaying the time the operator selected and 1 hour shall be subtracted from the current time which would make the offset for PST -7:00 hours instead of -8:00 hours.

When the Daylight Savings is selected as ‘OFF’ then no offset shall be applied to the current time.
