will automatically update and the TPM Telltale
Light will turn off once the system receives the
updated tire pressures. The vehicle may need to
be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this
information.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni-
toring Telltale Light off.
For example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard pressure of 30 psi (207 kPa). If the
ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 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 TPM Telltale Light. Driv-
ing the vehicle may cause the tire pressure to
rise to approximately 27 psi (186 kPa), but the
TPM Telltale Light will still be on. In this situa-
tion, the TPM Telltale Light will turn off only
after the tires are inflated to the vehicle's rec-
ommended cold placard pressure value.
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.
CAUTION!
• 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 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 TPM Telltale Light.
