Tire Pressure Monitoring Low Tire Pressure
Warnings
The "Tire Pressure Monitoring Telltale Light"
will illuminate in the instrument cluster, a
TIRE LOW PRESSURE message will display
in the instrument cluster, 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 tire pressure value (located
on the placard on the driver's-side B-Pillar). The system
will automatically update and the "Tire Pressure Moni-
toring Telltale Light" will extinguish once the updated
tire pressures have been received.
NOTE: The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.
The "Tire Pressure Monitoring Telltale Light" will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. 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 "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 TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
