For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 30 psi (207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi (186 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 23 psi (158 kPa). This tire
pressure is sufficiently low enough to turn ON the “TPM
Telltale Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa), but the
“TPM Telltale Light” will still be ON. In this situation, the
“TPM Telltale Light” will turn OFF only after the tires are
inflated to the vehicle’s recommended cold placard pres-
sure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to your local dealer to have your
sensor function checked.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.

WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

**Use only Chrysler recommended lug nuts/bolts and
clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated
against the wheel.
