Some main features of the ICU4M include:
-
Gauges that sweep 270 degrees and have pointers lit by an LED.
-
Service intervals that are programmable via two dash-mounted switches.
-
A warning chime and alert message to warn the driver if the door is opened without first setting the parking brake.
-
A flashing alert message that appears on the driver message center in low engine oil pressure or high coolant temperature conditions.
With the parking brake released, only the odometer and alert screens can be displayed. Park the vehicle and set the parking brake to display additional screens.
The dash message center displays alert screens when certain conditions occur. They are warnings, cautions, or other messages that require the driver's attention, but not all of them are critical to the operation of the vehicle. Warning messages always display at full brightness.
More important messages take priority over less important messages. The order of priority, is:
-
parking brake set (with the vehicle moving)
-
parking brake off (with door open)
-
low oil pressure or high coolant temperature
-
hard brake warnings (if equipped with roll stability advisor)
-
low battery voltage
-
ambient temperature below 35°F (1.7°C)
-
turn signal on
-
incoming instant or Qualcomm messages
-
service warnings
-
no datalink activity
Alert Screens
Note: If there is more than one alert message to display, pressing the +/- INFO switch or the MY INFO switch takes you to the next message, and so on, until all the messages have been received.
