Chrysler vehicles come with a tire pressure monitoring system (TPMS). This system monitors the vehicle's tire pressure and illuminates a warning light if the tire pressure is too low or too high. If you see a warning light, you'll need to set your TPMS by checking the vehicle's tire pressure and inflating or deflating the tires enough to meet the recommended inflation level. The tire pressure recommendation varies between Chrysler vehicles and tire types. You can reset the TPMS accordingly.

Air compressor or air tank
Turn the ignition key to "On" and push the "Info" button on the dash repeatedly, until the instrument cluster displays the pressure for each tire. Make a note of the current tire pressure according to the diagram. If you do not see the tire pressure in the cluster, your car does not have this feature. You'll have to manually check the pressure.
Remove the screw caps from each tyre's valve stem to manually check the tire pressure, if necessary. Apply the tire pressure gauge to the stem and record the reading. Repeat this for each tire, until you have determined the current tire pressure for each tire.
View the tire and loading information sticker on the driver side door jamb to determine the recommended tire pressure rating for each tire. Based on these figures, determine which tires you need to add air to, or remove air from, to set the TPMS. You can also find this information in your vehicle's owner manual. Check "Tire Pressure" in the index.
Attach the air nozzle from the air compressor or tank to the tyre's valve stem. Add air for three to five seconds, and then check the pressure rating with the tire gauge. For tires low on air, repeat this until the tire pressure reaches the recommended level.
Remove air from tires if you accidentally overinflate them, or if they had too much air to begin with. To remove air, push the centre prong in the tire valve stem using the back part of your pressure gauge, or a small tool, such as a screwdriver. Stop after a few seconds and check the tire pressure again with the gauge.
Replace all the valve stem caps when each tire is correctly inflated. Drive the vehicle for 15 to 20 minutes to allow the TPMS to set. The "Tire Pressure" warning light will go off.
