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.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pres-
sure of 30 psi (207 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 23 psi
(158 kPa). This tire pressure is sufficiently low enough
to turn on the TPMS Warning Light. Driving the vehicle
may cause the tire pressure to rise to approximately 27
psi (186 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 rec-
ommended cold placard pressure value
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. Aftermarket wheels
can cause sensor damage.
•
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 dealership to have your
sensor function checked.

CAUTION!
•
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.
•
If your vehicle is not equipped with the Tire Fill Alert
feature the TPMS should not be used as a tire pres-
sure 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 mainte-
nance, and it is the driver’s responsibility to main-
tain 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.
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
•
Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
•
Tire Pressure Monitoring System Warning Light
