a yellow light came on under the odometer..looks ! in yellow with a horseshoe symbol around it,whats does this mean..thanks

You need to get this vehicle to a dealer, it sounds as though you have a serious emission control warning light on. Typically the Service Engine light comes on for minor problems, but a light like this will come on for major problems which can lead to catalytic convertor damage. Have the dealership run it through a DRB scan and find out what is wrong.

This light is your tire pressure monitor. Check the pressure in your tires and fill them as needed. The light should then reset after a few miles of driving. Regards-RB

Yeah, like someone else mentioned it's the tire pressure monitoring system. Check all the tires (spare included), and push the reset button under the steering wheel if needed.

If the light is flashing, you most likely have a damaged or missing Tire Pressure Sensor. Get your tires changed lately? If it is constantly on, double check the pressure on all 5 TIRES. The spare is included in its readings. If the pressure are all the same, you will have to reset the system. There is a "set" button next to your hood latch. The owners manual discusses how and when to use it. But basically you hold it for 3+ seconds until you get 3 slow flashes and your baseline psi has been set.
