Don't pay attention to those idiot lights. Check the pressure in your tire with a pressure ga. If its a new car the pay for air will not give out the needed pressure for the tires some of those tires take 50lbs of air the pay for air things only put out about 38lbs you will lose air.

I'll probably just take it to a shop tomorrow. Im not very handy with cars and other stuff. My brother Ed tried to fill my tires once because of low tire pressure and overinflated them.

The cold weather can play some tricks with your TPMS. (From first hand experience.)

Tire pressure can decrease about 1 PSI (pound per square inch) for every 10 degrees the temperature drops,
as the air inside the tire condenses, taking up less space when it's cold.

It's similar to how a cake, just out of the oven, flattens out a bit as it cools.

Tires also lose about 1 PSI per month just from seepage of air around the edge of the rim and through the tread itself.

These two factors combined can cause the air pressure in a tire to go 25 percent below the recommended fill pressure.
This is what triggers the sensing transmitters inside your tires to illuminate your TPMS dash light.

Temperature changes outside affect your tire pressure. If it gets up to 45 degrees by day and drops to 15 degrees at night,
your tire pressure will vary 3 PSI, not counting normal air loss.

This is why it’s not unusual to have the low-pressure indicator light go on first thing in the morning, since it’s usually coldest overnight.

The light may shut off on its own after you drive 20 minutes or so, as the air in your tires warms and expands and proper inflation level stabilizes. If light still on, Top off your tires to recommended pressure listed on driver's side door jam.

Note: If the warning light is flashing, this is a problem with the vehicle’s TPMS system, not your tires, and you should take your car to the shop.
