2009 Nissan Altima Question: What does a yellow exclamation point inside an upside horseshoe on a gauge mean?
Answer #1pushrod January 30, 2014, 20:02Master
Let me guess, no owners manual~!! Which way is upside down for a horseshoe? If it's like an excl. mark inside a big U, with little marks at the botom it is the low tire pressure warning light, have tire pressures checked inclu. the 'spare' tire!!

Thats the TPMS (tire pressure monitoring system) icon. Check your tire pressures and make sure they are set to the specification on the door.

That is your TPMS light or tire pressure light.
