SAFETY
The system will automatically update and the
Tire Pressure Monitoring System Warning 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.
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 Tire Pressure Monitoring
System Warning Light. Driving the vehicle may
cause the tire pressure to rise to approximately
28 psi (193 kPa), but the Tire Pressure Moni-
toring System Warning Light will still be on. In
this situation, the Tire Pressure Monitoring
System Warning Light will turn off only after the
tires are inflated to the vehicle’s recommended
cold placard pressure value.
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 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
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 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 Tire Pressure Moni-
toring System Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
CAUTION!
The TPMS has been optimized for the orig-
inal equipment tires and wheels. TPMS
pressures and warnings have been estab-
lished for the tire size equipped on your
vehicle. Undesirable system operation 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 after-
market wheels and may contribute to a
poor overall system performance or sensor
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. 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 pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPM sensor.
