Tpms Deactivation - If Equipped; Fuel Requirements; 6.2L Supercharged And 6.4L Engine - Dodge Challenger SRT 392 2015 Operating Information Manual

TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter
wheel and tire assemblies on your vehicle To
deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) Sensors. Then, drive the vehicle for 20
minutes above 15 mph (24 km/h). The TPMS
will chime, the "TPM Telltale Light" will flash on
and off for 75 seconds and then remain on and
the Driver Information Display (DID) will display
the "SERVICE TPM SYSTEM" message and
then display dashes (--) in place of the pressure
values. Beginning with the next ignition switch
cycle, the TPMS will no longer chime or display
the "SERVICE TPM SYSTEM" message in the
DID but dashes (--) will remain in place of the
pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the "TPM
Telltale Light" will flash on and off for 75 sec-
onds and then turn off, and the Driver Informa-
tion Display (DID) will display the "SERVICE
TPM SYSTEM" message. The DID will also
display pressure values in place of the dashes.
On the next ignition switch cycle the "SERVICE
TPM SYSTEM" message will no longer be
displayed as long as no system fault exists.

WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent carbon monoxide poisoning:
• Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odor-
less gas, which can kill. Never run the
engine in a closed area, such as a garage,
and never sit in a parked vehicle with the
engine running for an extended period. If
the vehicle is stopped in an open area with
the engine running for more than a short
WARNING! (Continued)
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
• Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions re-
paired promptly. Until repaired, drive with
all side windows fully open.
• Keep the trunk closed when driving your
vehicle to prevent carbon monoxide and
other poisonous exhaust gases from en-
tering the vehicle.
