244 SAFETY
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can be
deactivated by 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 System (TPMS) sensors. Then,
drive the vehicle for 10 minutes above 15 mph (24 km/h).
The TPMS will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then remain on. The
instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display dashes (--) in place of
the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster 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 TPMS
sensors. Then, drive the vehicle for up to 10 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes.
On the next ignition cycle the "SERVICE TPM SYSTEM"
message will no longer be displayed as long as no system
fault exists.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature in the apps menu of the Uconnect system.
NOTE:

The Tire Fill Alert system will only support inflating or
deflating one tire at a time. The user is required to wait
until the hazard lights STOP flashing or 26-30 seconds
after the desired pressure is achieved in one wheel
before switching to another.
 The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the system is
in deactivation mode (if equipped).
The system will be activated when the system detects an
increase in tire pressure while filling the tire. The ignition
must be in the ON/RUN mode with the transmission in
PARK for vehicles equipped with an automatic
transmission. For vehicles equipped with a manual
transmission, the parking brake must be applied.
NOTE:
It is not required to have the engine running to enter Tire
Fill Alert mode.
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode. If the hazard lamps do not come on
while inflating the tire, the Tire Pressure Monitoring
System sensor may be in an inoperative position,
preventing the TPMS sensor signal from being received.
In this case, the vehicle may need to be moved slightly
forward or backward.
When Tire Fill Alert mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:

The horn will chirp once to let the user know when to
stop filling the tire, when it reaches recommended
pressure.
 The horn will chirp three times if the tire is overfilled
and will continue to chirp every five seconds if the user
continues to inflate the tire.

The horn will chirp once again when enough air is let
out to reach proper inflation level.

The horn will also chirp three times if the tire is then
underinflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
