Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle’s recommended cold tire pressure
value. The system will automatically update, the graphic
display of the pressure value(s) will stop flashing, and
the “Tire Pressure Monitoring Telltale Light” will extin-
guish once the updated tire pressure(s) have been re-
ceived.

NOTE:

The vehicle may need to be driven for up to

20 minutes above 15 mph (24 km/h) to receive this
information.

SERVICE TPM SYSTEM Message
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. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This text

message is then followed by a graphic display, with - - in
place of the pressure value(s) indicating which TPMS
Sensor(s) 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 “Tire Pressure Monitoring Telltale
Light” will no longer flash, the “SERVICE TPM SYSTEM”
message will not be present, and a pressure value will be
displayed instead of dashes. 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 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.
