page 391 on how to properly inflate the
vehicle’s tires.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the
low-pressure warning limit for any reason,
including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low
tire 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 Light)
illuminates, you must increase the tire pressure
to the recommended cold placard pressure in
order for the TPMS Warning Light to turn off.
The system will automatically update and the
Tire Pressure Monitoring System 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
recommended 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 Light. Driving the vehicle may cause the
tire pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring
System Light will still be on. In this situation, the
Tire Pressure Monitoring System 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
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni
-
toring System Light off.
CAUTION!
The TPMS has been optimized for the orig
-
inal equipment tires and wheels. TPMS
pressures and warning 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 TPMS
sensor is not designed for use on after
-
market wheels, and may contribute to a
poor overall system performance.
Customers are encouraged to use OEM
wheels to ensure 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 pres
-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.
