SAFETY
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 and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. 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.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pres-
sure of 33 psi (227 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn on
the TPMS Warning Light. Driving the vehicle may cause
the tire pressure to rise to approximately 28 psi
(193 kPa), but the TPMS Warning Light will still be on.
In this situation, the TPMS Warning Light will turn off
only after the tires are inflated to the vehicle's recom-
mended cold placard pressure value
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.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. The TPMS sensor is
not designed for use on aftermarket wheels, and
may contribute to a poor overall system perfor-
mance. Customers are encouraged to use Original
Equipment Manufacturer (OEM) wheels to ensure
TPMS feature operation.
•
Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealer to have your sensor function
checked.
•
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will pre-
vent moisture and dirt from entering the valve
stem, which could damage the TPMS sensor.
NOTE:
•
The TPMS is not intended to replace normal tire

care and maintenance, or to provide warning of a
tire failure or condition.
•
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure, unless
your vehicle is equipped with a Tire Fill Alert or
Selectable Tire Fill Alert feature.
•
Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping ability.

CAUTION!
•
The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to maintain
correct tire pressure using an accurate tire pressure
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.
System Operation
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 check the tire pres-
sure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPMS consists of the following components:
•
Receiver module
•
Four Tire Pressure Monitoring System sensors
