Wheels/Tires - Dodge Charger SRT 2018 Owner's Manual

158 SAFETY
Service Tire Pressure System 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 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 TPM Telltale 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 TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
Vehicles With Compact Spare
1. The compact spare tire or non-matching full size does
not have a tire pressure monitoring 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 Telltale 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 Telltale 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 Telltale 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.
