sures, the system will automatically update, the
graphic display in the EVIC will stop flashing, and
the Tire Pressure Monitoring Telltale Light will turn
off. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
Check 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. In addition, the EVIC
will display a
"
CHECK TPM SYSTEM
"
message for
three seconds and then display dashes (- -) in
place of the pressure value to indicate which
sensor is not being received.
If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. If the
system fault no longer exists, the Tire Pressure
Monitoring Telltale Light will no longer flash, and
the
"
CHECK 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. Jamming due to electronic devices or driving
next to facilities emitting the same Radio Frequen-
cies 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
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sen-
sors.
NOTE:
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire
assembly has a tire pressure monitoring sensor
that can be monitored by the TPMS.
2. If you install the full size spare in place of a
road tire that has a pressure below the low-
pressure warning limit, upon the next ignition key
cycle, a chime will sound and the Tire Pressure
Monitoring Telltale Light will turn ON. In addition,
the EVIC will display a Low Pressure message and
a graphic showing the low tire pressure value
flashing.
3. After driving the vehicle for up to 10 minutes
above 15 mph (25 km/h) the Tire Pressure Moni-
toring Telltale Light will turn OFF, as long as no tire
pressure is below the low-pressure warning limit in
any of the four active road tires.
4. The EVIC will display a graphic showing the tire
pressure value in place of the flashing low tire
pressure value. The EVIC will also display a
“SPARE LOW PRESSURE” message to remind
you to service the flat tire.
NOTE:
Vehicles with Compact Spare
1. The compact spare tire does not have a tire
pressure monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the compact spare
tire.
2. If you install the compact spare tire in place of
a road tire that has a pressure below the low-
pressure warning limit, upon the next ignition key
cycle, the Tire Pressure Monitoring Telltale Light
will remain ON and a chime will sound. In addition,
the graphic in the EVIC will still display a flashing
pressure value.
3. After driving the vehicle for up to 10 minutes
above 15 mph (25 km/h), the TPM Telltale Light
will flash on and off for 75 seconds and then
remain on solid. In addition, the EVIC will display
