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 pres-
sure value. The system will automatically update and the
“Tire Pressure Monitoring Telltale Light” will extinguish
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.
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and will remain on solid when a
system fault is detected. 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 by
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. Lots of snow or ice around the wheels or wheel hous-
ings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles not equipped with instrument cluster display will
inform the driver which tire(s) are low but not provide
actual tire pressure. The low tire ISO telltale will illuminate
along with “LoTIrE” message displayed in the ODO and
then it will scroll to which tire location is lower than the
Placard Value.
Tire location will be displayed as follows:
LF = Left Front
rF = right Front
Lr = Left rear
rr = right rear
NOTE:
•
If your vehicle is equipped with a matching full-size spare
wheel and tire assembly, it has a tire pressure monitoring
sensor, and can be monitored by the Tire Pressure Moni-
toring System (TPMS) when swapped with a low pressure
road tire. In the event that the matching full-size spare tire
