• The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
• Driving on a significantly under-inflated
tire causes the tire to overheat and can
lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ability.
• The TPMS is not a substitute for proper
tire maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the "Tire Pressure Monitoring Telltale
Light."
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.

Base System

The Tire Pressure Monitor System (TPMS) uses
wireless technology with wheel rim mounted
electronic sensors to monitor tire pressure lev-
els. 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 check
the tire pressure in all of your tires regularly
and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS) con-
sists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in
the spare wheel if the vehicle is equipped with
a matching full size spare wheel and tire as-
sembly. The matching full size spare tire can be
used in place of any of the four road tires. A low
spare tire will not cause the "Tire Pressure
Monitoring Telltale Light" to illuminate or the
chime to sound.

The "Tire Pressure Monitoring Telltale
Light" will illuminate in the instrument
cluster, a "LOW TIRE" message will be
displayed for a minimum of five sec-
onds and an audible chime will be activated
when one or more of the four active road tire
pressures are low. Should this occur, you
should stop as soon as possible, check the
inflation pressure of each tire on your vehicle,
and inflate each tire to the vehicle's recom-
mended cold placard pressure value. The sys-
tem will automatically update and the "Tire
Pressure Monitoring Telltale Light" and "LOW
TIRE" message will extinguish once the up-
dated tire pressures have been received. The
vehicle may need to be driven for up to 20 min-
utes above 15 mph (24 km/h) to receive this
information.
The "Tire Pressure Monitoring Telltale Light" will
flash on and off for 75 seconds, and will remain
on solid when a system fault is detected. The
system fault will also sound a chime. If the
ignition key is cycled, this sequence will repeat,
providing the system fault still exists. A system
fault can occur by any of the following sce-
narios:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same Radio
Frequencies as the TPM sensors.
