Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, a “Inflate Tire to XX”
message will be displayed for a minimum of five sec-
onds, and an audible chime will be activated when one or
more of the four active road tire pressures are low. 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. The recommended cold placard pressure
value is the pressure value in the ⬙Inflate Tire to XX⬙
message displayed in the EVIC. The system will auto-
matically update and the Tire Pressure Monitoring Light
will extinguish and the “Inflate Tire to XX” message will
turn off once the updated tire pressures have been
received. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.
Service TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on solid when a
system fault is detected. The system fault will also sound
a chime and display a “SERVICE TPM SYSTEM” mes-
sage for a minimum of 5 seconds. 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 with any of the following
scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
