What does dash light shaped like upside down horseshoe w/ explanationpoint in center mean? Its to the right of wiper liquid indicator

low tire pressure warning lite

describe it more clearly, which direction is "upside-down" for a horseshoe??? is it a pair of parentheses with a line under it you mean? might be your low tire pressure light, happens when any tire is 25% below the recommended tire pressure.

That light is your Low Pressure indicator from your Tire Pressure Monitoring System... Check your tire pressures, bring them up to specs and the light will go out in a few miles.

You have problem with the tire pressure. The nissan pathfinde have a TIME PRESSURE MONITORING SYSTEM (TPMS) That means: This systems monitoring the pressure warning light iluminates, check the tire pressure in all four tires. Adjust the low pressure to the recommended cold tire pressure shown on theTire and Loading Information label located in the driver's door opening. After the pressure are adjusted, the vehicle will need to be driven at speed above 16 MPH (25 km/h) to activate the TPMS and turn off the low pressure warning light.

You are right. Tire pressure symbol looks like a horseshoe tire shape.

It should be letting you know that you have a tire pressure problem. If you still have the owners manual read it. It will explain what to do, what to look for and how to reset the light if need be.

I believe it's the washer fluid light

this is the tire pressure warning.

it is the low tire pressure indicator, you have low tire pressure in one or more of the tires

that means that you need air in one of you tires. you have the TPMS or tire pressure monitor system when your tires are below the ideal pressure it will light the icon in the dash. the way to tell if you have this it to look at the tire stems the place where you put in the air if there silver you do have it. if there black you don't
there should also be a yellow light on the dash that comes on when you turn the key on or start the car that reads "TPMS"
hope that this helps
