the vehicle’s recommended cold placard pressure infla-
tion value. Once the system receives the updated tire
pressures, the system will automatically update, the
graphic display in the DID will return the pressure values
shown to their original color, and the “TPM Telltale
Light” will turn off. The vehicle may need to be driven
for up to 10 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
NOTE: When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
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. In addition, the
DID will display a ⬙SERVICE TPM SYSTEM⬙ message for
a minimum of five seconds and then display dashes (- -)
in place of the pressure value to indicate which sensor is
not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “TPM Telltale Light” will no longer
flash, and the ⬙SERVICE TPM SYSTEM⬙ message will no
longer display, and a pressure value will display in place
of the dashes. 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.
