For example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard pressure of 33 psi (227 kPa). If the
ambient temperature is 68°F (20°C) and the
measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to
turn ON the “TPMS W arning Light.” Driving the
vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the TPMS
W arning 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 recom-
mended cold placard pressure value.
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 W arning
Light off.
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 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-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle to
your authorized dealer to have your sensor
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 TPMS 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 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 responsi-
bility 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 TPMS W arning Light.
• Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the ac-
tual tire pressure in the tire.
