For what it's worth, I once noticed my wife's 2007 Camry had tires that looked low after a drive one day (never a good sign on high-profile 215/60/R16 tires). Sure enough, they measured at 16-18 lbs. each, or half of what Toyota wants. It never triggered the low tire pressure light.
You should actually measure the tire pressure on your Camry and see how low it is. As long as there's more than 15 or so pounds, you can safely drive a bit to fill them up. As Bob Cross mentioned, keep an eye on the sudden maneuvers. Low tires get hot, risking a blowout, and they resist sharp turns in direction--which includes braking hard.
I keep a quality tire pressure gauge in my trunk because I'm not sure you can trust some of the TPMS implementations.
