4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
The EVIC will also display a ЉSERVICE TPM SYSTEMЉ
message for a minimum of five seconds when a system
fault is detected possibly related to an incorrect sensor
location fault. In this case, the
ЉSERVICE TPM SYSTEMЉ
message is then followed by a graphic display, with
pressure values still shown. This indicates the pressure
values are still being received from the TPM Sensors but
they may not be located in the correct vehicle position.
However, the system still needs to be serviced as long as
the
ЉSERVICE TPM SYSTEMЉ message exists.
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 Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition switch cycle will
still show the “Tire Pressure Monitoring Telltale Light”
to be ON, a chime to sound, a “LOW TIRE PRES-
SURE” message to appear in the EVIC, and the graphic
display will still show the
ЉInflate to XXЉ message and
the low tire pressure value “flashing.” Driving the
vehicle for up to 20 minutes above 15 mph (24 km/h)
will turn OFF the “Tire Pressure Monitoring Telltale
Light” as long as none of road tires are below the low
pressure warning threshold.
