Dodge Charger 392 SRT Hellcat 2017 Owner's Manual page 386

384 STARTING AND OPERATING
NOTE: When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
Service TPMS Warning
If a system fault is detected, the "TPM Telltale Light" will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
instrument cluster will display a SERVICE TPM SYSTEM
message for a minimum of five seconds and then display
dashes (- -) in place of the pressure value to indicate which
sensor is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the "TPM Telltale Light" will no longer flash,
the SERVICE TPM SYSTEM message will no longer
display, and a pressure value will display in place of the
dashes. A system fault can occur due to any of the
following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles With Compact Spare
1. The compact spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the pressure in the
compact spare tire.
2. If you install the compact spare tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the "TPM
Telltale Light" will remain ON and a chime will sound.
In addition, the graphic in the instrument cluster will
still display the low pressure values in a different color
and an "Inflate to XXX" message.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the "TPM Telltale Light" will flash
on and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a SERVICE
