396 STARTING AND OPERATING
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The matching full size spare
can be used in place of any of the four road tires. The
TPMS will only monitor the pressure in the full size spare
when it is used in place of a road tire. Otherwise, a spare
with a pressure below the low-pressure limit will not
cause the TPM Telltale Light to illuminate or the chime to
sound.
Tire Pressure Monitoring Low Pressure Warnings
The TPM Telltale Light will illuminate in the
instrument cluster, a LOW TIRE message will be
displayed and a chime will sound when tire pres-
sure is low in one or more of the four active road tires.
Should this occur, you should stop as soon as possible,
check the inflation pressure of each tire on your vehicle,
and inflate each tire to the vehicle's recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update and the TPM Telltale Light and LOW TIRE
message 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.
Service TPMS 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. If the ignition
switch is cycled, this sequence will repeat, providing the
system fault still exists. The TPM Telltale Light will turn
off when the fault condition no longer exists. A system
fault can occur due to any of the following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
