cause the tire pressure to rise to approximately
28 psi (193 kPa), but the "Tire Pressure Monitor-
ing Telltale Light" will still be on. In this situation,
the "Tire Pressure Monitoring Telltale Light" will
turn off only after the tires are inflated to the
vehicle's recommended cold placard pressure
value.
CAUTION!
• The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warnings have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. The
TPM sensor is not designed for use on
aftermarket wheels and may contribute to
a poor overall system performance or sen-
sor damage. Customers are encouraged to
use OEM wheels to assure proper TPM
feature operation.
• Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
CAUTION!
ter using an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealership to have your sen-
sor function checked.
• After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the TPM sensor.
NOTE:
• The TPMS is not intended to replace normal
tire care and maintenance, or to provide warn-
ing of a tire failure or condition.
• The TPMS should not be used as a tire pres-
sure 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 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 responsibil-
ity 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
Telltale Light".
• Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the ac-
tual 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 lev-
els. 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
• Various tire pressure monitoring system mes-
sages, which display in the instrument cluster
• Tire pressure monitoring telltale light
