After a battery failure (loss of charge or battery replacement) critical safety features are disabled until the car is returned to a dealer to "program the new battery". the safety features that are disabled include: 1) turn signals, 2) 4 way flashers, 3) front windows lowering, 3) control of the headlights (no control of dims and bright lights), and 4) dash lights (can't see the speedometer). while a simple warning light in this situation would work, the manufacturer chose to disable critical safety functions of the car. in my case, its a 1 1/2 drive in an unsafe car to get the situation corrected. this situation is being experienced by other drivers and others can be found with a simple google search.
