Supposedly it is referring to the key fob battery (KeyFob #1 or #2).
The "RAF 2 Batteries Low Light" on a 2003 Chevy Tahoe typically indicates a problem with the vehicle's battery or charging system. It suggests that the vehicle's electrical system is not receiving adequate power, possibly due to a weak or failing battery, a faulty alternator, or poor electrical connections. It's important to check the battery's charge and condition, as well as the alternator's output, to diagnose and resolve the issue. Ignoring this warning could lead to further electrical problems or a dead battery.
They probably mean a Chevy Tahoe. It is the name of a vehicle, and specifically an SUV.
More the likely the alternator has quite working are the belt / belts have broken on the front of the engine.
That means the engine is running HOT. Need to check the coolant level and check for coolant leaks.
