Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument
cluster, an
ЉInflate to XXЉ message will be displayed and
a chime will sound when tire pressure 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 as shown in the
ЉInflate to XXЉ message. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” 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
When a system fault is detected, the “Tire Pressure
Monitoring 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 key is cycled, this
sequence will repeat, providing the system fault still
exists. The “Tire Pressure Monitoring Telltale Light” will
turn off when the fault condition no longer exists. A
system fault can occur due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel hous-
ings.
