148 SAFETY
(Continued)
including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low
tir
e pressure as long as the condition exists,
and will not turn off until the tire pressure is at
or above the recommended cold placard
pressure. Once the low tire pressure warning
(Tire Pressure Monitoring System Warning
Light) illuminates, you must increase the tire
pressure to the recommended cold placard
pressure in order for the TPMS Light to turn off.
The system will automatically update and the
TPM
S 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
rec
ommended 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
eno
ugh to turn on the TPMS Warning Light.
Driving the vehicle may cause the tire pressure
to rise to approximately 28 psi (193 kPa), but
the TPMS Warning 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
recommended cold placard pressure value.
NOTE:
When filling warm tires, the tire pressure may
n
ee
d to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.
NOTE:
The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.
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 responsi-
bility to maintain correct tire pressure using
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 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
aftermarket wheels, and may contribute to
a poor overall system performance.
Customers are encouraged to use OEM
wheels to assure TPMS 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 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.
CAUTION! (Continued)
