SAFETY 151
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
abo
ve 15 mph (24 km/h) in order for the
TPM
S to receive this information.
Vehicles With a Full Size Matching Spare
1. If your vehicle is equipped with a matching
fu
ll-size spare wheel and tire assembly, it
has a tire pressure monitoring sensor, and
can be monitored by the Tire Pressure
Monitoring System (TPMS) when swapped
with a low pressure road tire.
2. In the event that the matching full-size
sp
are tire is swapped with a low pressure
road tire, the next ignition switch cycle will
still show the TPMS Warning Light to be on,
a chime to sound, an “Inflate to XX”
message to appear in the instrument
cluster, and the graphic display will still
show the low tire pressure value in a
different color.
3. Driving the vehicle for up to 20 m
inutes
abo ve 15 mph (24 km/h) will turn off the
TPM
S Warning Light as long as none of road
tires are below the low pressure warning
threshold.
Tire Fill Alert
This feature notifies the user when the placard
tir
e 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:
Only one tire can be filled at a time when
using the Tire Fill Alert system.
The Tire Fill Alert feature cannot be entered if
an existing TPM system fault is set to “active”
or if the system is in deactivation mode (if
equipped).
The system will be activated when the system
det
ects 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 park brake must be
applied.
NOTE:
It is not required to have the engine running to
ent
er Tire Fill Alert Mode.
The hazard lamps will come on to confirm the
veh
icle is in Tire Fill Alert mode. If the hazard
lamps do not come on while inflating the tire,
the Tire Pressure Monitoring (TPM) sensor may
be in an inoperative position, preventing the
TPM 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
pre
ssure 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
over filled 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.
