There may be a “Heavy Fuel Use” message on the Driver Information Center (DIC) (Fig. 11) at times while driving on some 2023-2025 Escalade, Silverado 1500, Tahoe, Suburban, Sierra 1500, Yukon; 2024-2025 Silverado 2500HD/3500HD and Sierra 2500HD/3500HD models.
Fig. 11
The DIC message will be displayed when the fuel range is low and the vehicle is consuming more fuel because of aggressive driving or towing. (Fig. 12)
The “Heavy Fuel Use” message indicates that the fuel range may be decreased due to current driving habits. It is an informational message for the driver to help in understanding the current operating status of the vehicle and is a normal condition.

If this message is displayed, it does not indicate any concerns with the fuel system. No repairs are necessary.
