SAFETY 301
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 recommended cold
placard pressure value.
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 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 effi-
ciency 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 using an accu-
rate 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
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Example: Tire Pressure Monitoring System Display
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 monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four TPMS sensors
Various TPMS messages, which display in the
instrument cluster
TPMS Warning Light
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. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS) sensor
to become inoperable. After using an after-
market tire sealant it is recommended that you
take your vehicle to an authorized dealership to
have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPMS sensor.
