• The TPMS is not a substitute for proper tire
maintenance, and it is t he driver’s responsibility
to maintain correct tire pressure using an
accurate tire gauge, 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
This is the TPMS warning indicator lo-
cated in the instrument cluster.
The TPMS uses wireless technology with wheel
rim mounted electronic sensors 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 check the
tire pressure in all of the tires on your vehicle
regularly and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, an acoustic
signal will be activated, and the “Check left or
right front/rear tire” text message will display
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 recommended cold
placard pressure value. The system will automati-
cally update and the Tire Pressure Monitoring
Light will extinguish once the updated tire pres-
sures 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.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will
flash on and off for 75 seconds and remain on
solid when a system fault is detected, an audible
chime will be activated and the “Service Tire
Pressure Monitoring System” text message will
display. If the ignition is cycled, this sequence
will repeat providing the system fault still exists.
The Tire Pressure Monitoring Telltale Light will
turn off when the fault condition no longer exists.
A system fault can occur with any of the following
scenarios:
• Jamming due to electronic devices or driving
next to facilities emitting the same radio fre-
quencies as the TPM sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.
• Snow or ice around the wheels or wheel
housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM
sensors.
NOTE:
Your vehicle may be equipped with a compact
spare wheel and tire assembly.
• The compac t spare tire does not have a tire
pressure monitoring sensor. Therefore, the
TPMS will not monitor the tire pressure in the
compact spare tire.
