All of the customizable options listed may not be available on your vehicle. Only the options available will be displayed on your Driver Information Center (DIC). The default settings for the customization features were set when your vehicle left the factory, but may have been changed from their default state since then. To change feature preferences, make sure the ignition is on and the vehicle is in PARK (P). Press the customization button to scroll through the available customizable options. After pressing the customization button, VEHICLE SETTINGS will momentarily display before going to a customization option. A temporary solution to hotter transmission operating temperatures may be to let the transmission cool down. If the transmission is operated at higher temperatures on a frequent basis, see Scheduled Maintenance on page 6-4 for the transmission your vehicle is equipped with for the proper transmission maintenance intervals.

Pressing any of the four DIC buttons will acknowledge the message and clear it from the DIC display. If your vehicle does not have the four DIC buttons, pressing the trip odometer reset stem will acknowledge the message and clear it from the DIC display. 3-67
