DIC Warnings and Messages 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. Some messages may not require immediate action, but you can press any of the DIC buttons on the instrument panel or the trip odometer reset stem on the instrument panel cluster to acknowledge that you received the messages and to clear them from the display. 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. The following are the possible messages that can be displayed and some information about them. ALL WHEEL DRIVE OFF If your vehicle has the All-Wheel Drive (AWD) system, this message displays when there is a compact spare tire on the vehicle, when the Anti-lock Brake System (ABS) warning light comes on, or when the rear differential fluid is overheating. This message turns off when the differential fluid cools. The AWD system is disabled until the compact spare tire is replaced by a full-size tire. If the warning message is still on after putting on the full-size tire, you need to reset the warning message. To reset the warning message, turn the ignition off and then back on again after 30 seconds. If the message stays on, see your dealer/retailer right away. See All-Wheel Drive (AWD) System on page 339 for more information. AUTOMATIC LIGHT CONTROL OFF This message displays when the automatic headlamps are turned off. This message clears itself after 10 seconds. 244
