Fuel Gauge & DTE Notes:

• The fuel gauge will function properly, though it may stay at “Full” until ~4–5 gallons are used.

• DTE (Distance to Empty) cannot be reprogrammed on GM trucks and may reflect only half the actual range.

• If the truck temporarily shows "Empty" at full tank, a simple restart will reset the gauge behavior.

• The larger footprint of the tank offers a greater fuel reserve when the low fuel light activates.
