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.
