Jeep 2004 Liberty - Manual (Page 255)

The following chart indicates the TPM system pressure
levels. A threshold is the level at which the TPM system
provides you with an indication.
High Pressure Threshold 44 psi (303 kPa )
Placard Pressure (Cold) 33 psi (227 kPa)
Low Pressure Threshold 25 psi (172 kPa)
NOTE: A TPM system does not replace normal tire
maintenance.
CAUTION!
• The TPM system has been optimized for the
original equipment tires and wheels. TPM system
pressures have been established for the tire size
equipped on your vehicle. Undesirable operation
or sensor damage may result when using replace-
ment equipment that is not of the same size, type,
and/or style. Aftermarket wheels can cause sensor
damage. Do not use tire sealant or balance beads
if your vehicle is equipped with TPM system as
damage to the sensors may result.
• 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 wheel rim sensor.
