That is the tire pressure monitoring light. Simply air up your tires and it will turn off. If it comes back on then you may have a slow leak.

I had this, red ! came on briefly around bends and after short stop at lights etc. It was low brake fluid so as it would slosh to one side it would drop below level and display warning. Check and top up asap.

The warning light that looks like a pot or kettle with arrows is the "Low tire pressure warning light*" I found the answer on the Toyota web site by registering, logging in, entering my model and searching the owners manuals for warning lights.

That light means that you are setting the tire pressure guage. there is nothing wrong with the van.
