Many Chrysler vehicles are equipped with tire pressure monitoring systems, or TPMSs, that display warnings on the vehicles' instrument panels if the air pressure in any of the vehicles' tires become underinflated. The TPMS warning light stays on as long as the low tire pressure condition exists. The only way to reset the system is to correct the underinflation by adding air to whichever tire or tires need it, then giving the Chrysler a chance to detect the change while you're driving.

Step 1

Park the car on a flat surface. Turn off the engine.

Step 2

Remove the cap from the valve stem of one tire. Press the head of the tire pressure gauge over the valve stem firmly so that it creates a seal around the stem, holding air in the tire. Pull the gauge off the stem and note the gauge's reading. If the pressure is below the manufacturer's recommended pressure, you'll have to add air. Go to Step 3.

Step 3

Press the nozzle of your compressed air source onto the valve stem for any tire that needs air to be added. Remove the nozzle after a few seconds and measure the pressure with the gauge again. Continue this process until each tire is inflated to the proper pressure. Recommended pressure for each tire is printed on the side of the tire.

Step 4

Replace the cap on the valve stem when the tire has the proper amount of air, then move to another tire. Follow these steps on all four tires.

Step 5

Start the engine. Drive the vehicle for up to 20 minutes, above 15 mph, to give the TPMS a chance to detect the pressure accurately and reset itself.
