Chrysler 300 2022 Owner's Manual page 161

Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those shown in a different color in the
instrument cluster graphic) to the vehicle's
recommended cold placard pressure inflation
value as shown in the "Inflate to XX" message.
Once the system receives the updated tire
pressures, the system will automatically update,
the graphic display in the instrument cluster will
change color back to the original color, and the
TPMS Warning Light will turn off. The vehicle may
need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive
this information.
NOTE:
When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the TPMS Warning Light off.
Service TPMS Warning
If a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning 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 Tire
Pressure 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 TPMS Warning Light
will no longer flash, and the "Service Tire Pressure
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:
Signal interference due to electronic devices or

driving next to facilities emitting the same radio
frequencies as the TPMS sensors.
Accumulation of snow or ice around the wheels

or wheel housings.
Using tire chains on the vehicle.

Using wheels/tires not equipped with TPMS

sensors.
Vehicles With Compact Spare
1. The compact spare tire or non-matching full size
does not have a Tire Pressure Monitoring
System sensor. Therefore, the TPMS will not
monitor the pressure in the compact spare tire.
2. If you install the compact or non-matching full
size spare tire in place of a road tire that has a
pressure below the low-pressure warning limit,
upon the next ignition key cycle, the TPMS
Warning Light will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a different
color pressure value and an "Inflate to XX"
message.
3. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the TPMS Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, the
instrument cluster will display a "Service Tire
Pressure System" message for five seconds
and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a
chime will sound, the TPMS Warning Light will
flash on and off for 75 seconds and then
remain on solid, and the instrument cluster will
display a "Service Tire Pressure System"
message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road
tire and reinstall it on the vehicle in place of
the compact spare or non-matching full size,
the TPMS will update automatically. In
addition, the TPMS Warning Light will turn off
and the graphic in the instrument cluster will
display a new pressure value instead of
dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any of
the four active road tires. The vehicle may
need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.
