using an accurate tire pressure
gauge, even if under-inflation
has not reached the level to trig-
ger illumination of the TPM
Telltale Light.
Seasonal temperature changes will affect tire pressure, and the
TPMS will monitor the actual
tire pressure in the tire.
PREMIUM SYSTEM
The Tire Pressure Monitor System
(TPMS) uses wireless technology with
wheel rim mounted electronic sensors
to monitor tire pressure levels. Sen-
sors mounted to each wheel as part of
the valve stem transmit tire pressure
readings to the receiver module.
NOTE:
It is particularly important for you
to check the tire pressure in all of
the tires on your vehicle monthly
and to maintain the proper pres-
sure.
The TPMS consists of the following
components:
Receiver module,
Four TPM sensors, Various TPMS messages, which
display in the Electronic Vehicle In-
formation Center (EVIC), and
TPM Telltale Light
Tire Pressure Monitoring Low
Pressure Warnings The TPM Telltale Light will il-
luminate in the instrument
cluster and a chime will sound
when tire pressure is low in one or
more of the four active road tires. In
addition, the EVIC will display a
"LOW TIRE" message and a graphic
showing the pressure values of each
tire with the low tire pressure values
flashing.
Should this occur, you should stop as
soon as possible and inflate the tires
with a low pressure condition (those
flashing in the EVIC graphic) to the
vehicle’s recommended cold placard
pressure inflation value. Once the sys-
tem receives the updated tire pres-
sures, the system will automatically
update, the graphic display in the
EVIC will stop flashing, and the TPM
Telltale Light will turn off. The ve-
hicle may need to be driven for up to 20 minutes above 24 km/h in order
for the TPMS to receive this informa-
tion.
Service TPMS Warning
If a system fault is detected, the TPM
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 dis-
play a "SERVICE TPM SYSTEM"
message for a minimum of five sec-
onds and then display dashes (- -) in
place of the pressure value to indicate
which sensor 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 TPM Tell-
tale Light will no longer flash, and the
"SERVICE 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. Signal interference due to elec-
tronic devices or driving next to facili-
ties emitting the same radio frequen-
cies as the TPM sensors.
