NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide warning of a tire failure or condition.
• The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
• Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation 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 respon-
sibility to maintain correct tire pressure
using an accurate tire pressure gauge, even
if underinflation has not reached the level
to trigger illumination of the "Tire Pressure
Monitoring Telltale Light".
• Seasonal temperature changes will affect
TPMS information on your instrument
cluster.
Base System
The Tire Pressure Monitor System (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 monthly and to maintain the proper
pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warn-
ings
The "Tire Pressure Monitoring Tell-
tale Light" will illuminate in the in-
strument cluster, a "LOW TIRE
PRESSURE" message will display in the in-
strument cluster, an "Inflate to XX" message
will be displayed and a chime will sound
when tire pressure is low in one or more of the
four active road tires. 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 as
shown in the "Inflate to XX" message. Once
the system receives the updated tire pres-
sures, the system will automatically update
and the "Tire Pressure Monitoring Telltale
Light" will turn off.
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 plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off. The vehicle may
need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.
Service TPMS Warning
When a system fault is detected, the "Tire
Pressure Monitoring Telltale Light" will flash
on and off for 75 seconds and then remain on
