CAUTION! (Continued)
Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come 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.
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the TPM 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.
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation
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 maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the Tire Pressure Monitoring
System Warning Light.
Seasonal temperature changes will affect tire pressure, and
the TPMS will monitor the actual tire pressure in the tire.
Premium 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 components:
Receiver module
Four tire pressure monitoring sensors
Various tire pressure monitoring system messages,
which display in the instrument cluster
Tire Pressure Monitoring System Warning Light
