2009 Nissan Altima Q&A
2009 Nissan Altima Question: What does a yellow exclamation point inside an upside horseshoe on a gauge mean?
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!! - pushrod
Thats the TPMS (tire pressure monitoring system) icon. Check your tire pressures and make sure they are set to the specification on the door. - cardocIII
AGREE WITH #2 - globalhelper
That is your TPMS light or tire pressure light. - Express Auto
