I had an Elantra 2010. I do not recommend them.

First have someone check the airbag system codes.The light will not stay out if there is a defect in the system.It's usually the drivers seat belt buckle or belt retractor switch.

Change the thermostat and make sure to bleed the system of air when refilling with coolant.You should have lots of heat in a 2005 Elantra at idle or driving.

Check for a switch along (and next to) the arm of the brake pedal. Sometimes there is a plastic piece on the arm that presses a plunger in when you let off the brakes. If that plastic piece breaks, nothing pushes the plunger in on the switch to turn off the lights when you let off the pedal. Had this issue on my 97 Accord. Or the switch itself could be bad.

With some makes and models, if battery voltage is lost, some modules may have to relearn or be reprogrammed? I can't tell from here if that is your problem? Just a thought. Will the vehicle start and run? Is it driveable? Any applicable fuses, did you check voltage at fuse circuit, use a test lite. I try to suggest people use a memory saver or charger, to keep systems alive if battery or battery cable needs to be disconnected. Battery has a full charge and battery connections all good?

THE BATTERY IS NOT FULLY CHARGED.

There is something on or shorted to drain your battery, then voltage is too low for starter.
