how can i reset my car so it wont turn off once it hits 24 miles left til empty
You can't change that parameter. Do not run the tank much below 1/8 to 1/4 of a tank or you risk ruining the fuel pump. Today's cars do not like being run out of fuel.
24 miles to e is basically no gas in the tank, those readings are jus estimates and not numbers you should trust when it's that low,
