DIC Warnings and Messages

Under certain conditions, the Driver Information Center (DIC) may display a message regarding the folding hardtop. These messages will appear when a problem is sensed in one of the vehicle's systems. Press RESET to clear the display screen.

DIC messages can be displayed in English, French, German, Italian and Spanish.

CLOSE CARGO COVER: This message indicates that the cargo cover is not in place. Open the rear compartment and make sure the cargo cover is secure and no objects are on the cover.

LOW VOLTAGE: This message will appear when the electrical system is charging less than 10 volts or if the battery has been drained. If this message appears immediately after starting, it is possible that the generator can still recharge the battery. The battery should recharge while driving but may take a few hours to do so. Consider using an auxiliary charger (be sure to follow the manufacturer's instructions) to boost the battery after returning home or to a final destination. If this message appears while driving or after starting your vehicle and stays on, have it checked immediately to determine the cause of this problem. To help the generator recharge the battery quickly, you can reduce the load on the electrical system by turning off the accessories. You can monitor battery voltage on the DIC by pressing the INFO button. The normal range is 11.5-15.5 volts.
