Hello, juist bought a used f150 fx4 with 110,000 miles. Im just curious if the part on the dash that tells you your total mileage should illuminate like the odometer, or if is only allowed to be seen during day time. Also is there a function to see how many miles you have left till you run out of gas, or how cold it is outside? once in awhile i hear a chime and have no idea what its chimeing for, maybee icey roads?? Thanks for any help
