CAUTION!

• Using aftermarket tire sealants may

cause the Tire Pressure Monitoring Sys-
tem (TPMS) sensor to become inoper-
able. 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 prevent moisture and dirt
from entering the valve stem, which
could damage the TPMS sensor.

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 TPMS Warning
Light.

• Seasonal temperature changes will affect

tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.

System Operation

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

  • Using aftermarket tire sealants may cause the Tire Pressure Monitoring Sys- tem (TPMS) sensor to become inoper- able.
  • After inspecting or adjusting the tire pressure always reinstall the valve stem cap.
  • 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.
  • 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 TPMS Warning Light.
  • Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
