DIC Warnings and Messages Base and Uplevel Systems

Messages are displayed on the DIC to notify the driver that the status of the vehicle has changed and that some action may be needed by the driver to correct the condition. Multiple messages may appear one after another.

The DIC monitors some fluid levels, battery of the Remote Keyless Entry (RKE) transmitter, the theft-deterrent system on vehicles with this feature, the brake light switch, and important exterior lights, including wiring and fuses.

Some messages may not require immediate action, but you can acknowledge that you received the messages and to clear them from the display by doing one of the following:

    • Press the OK button on the base level audio system.
    • Press the multifunction knob, if your vehicle has this feature, on the uplevel audio system.
    • Press the left thumbwheel, if your vehicle has this feature, on the steering wheel.

If there are several warning messages, acknowledge them one at a time.

Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. You should take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem.

Warning messages for the uplevel DIC follow. On the base level DIC, messages appear in an abbreviated form.
