The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to main-
tain correct tire pressure using an accurate tire
gauge, even if underinflation has not reached the
level to trigger illumination of the TPMS Warning
Light.
•
Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire pres-
sure in the tire.
The Tire Pressure Monitoring System (TPMS) uses wire-
less technology with wheel rim-mounted electronic sen-
sors to monitor tire pressure levels. Sensors, 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 regularly check the
tire pressure in all of your tires and to maintain the
proper pressure.
The Tire Pressure Monitoring System (TPMS) consists of
the following components:
•
Receiver module
•
Four Tire Pressure Monitoring System sensors
•
Various Tire Pressure Monitoring System messages,
which display in the instrument cluster, and a
graphic displaying tire pressures
•

Pressure Warnings
The TPMS Warning Light will illuminate in the
instrument cluster, and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. In addi-
tion, the instrument cluster will display an "Inflate to XX"
message and a graphic display of the pressure value(s)
with the low tire(s) in a different color
page 95.
NOTE:
Your system can be set to display pressure units in PSI,
BAR, or kPa.
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 in a different color on
the graphic display to the vehicle’s recommended cold
tire pressure displayed in the “Inflate to XX” message.
NOTE:
When filling warm tires, the tire pressure may need to
be increased up to an additional 4 psi (28 kPa) above
the recommended cold placard pressure in order to
turn the TPMS Warning Light off.
The system will automatically update, the graphic dis-
play of the pressure value(s) will return to its original
color and the TPMS Warning Light will extinguish once
the updated tire pressure(s) 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.
Service TPMS Warning
The Tire Pressure Monitoring System Warning 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 instrument cluster display will
display a “SERVICE TPM SYSTEM” message for a mini-
mum of five seconds. This message is then followed by
a graphic display, with “--“ in place of the pressure val-
ue(s), indicating which Tire Pressure Monitoring System
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 System
Warning Light will no longer flash, the "SERVICE TPM
SYSTEM" message will not be present, and a pressure
value will be displayed instead of dashes.
