to “Tires” in “Servicing And Maintenance” for
information on how to properly inflate the vehi-
cle’s tires. The tire pressure will also increase as
the vehicle is driven - this is normal and there
should be no adjustment for this increased pres-
sure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the low
pressure warning threshold for any reason, in-
cluding low temperature effects, or natural pres-
sure 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 recommended cold tire pressure. Once
the low tire pressure warning has been illumi-
nated, the tire pressure must be increased to
the recommended cold tire pressure in order for
the TPMS W arning Light to be turned off.
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 Warning
Light off.
The system will automatically update and the
TPMS Warning Light will extinguish once the
updated tire pressures have been received. The
vehicle may need to be driven for up to 20 min-
utes above 15 mph (24 km/h) to receive this
information.
For example, your vehicle has a recommended
cold (parked for more than three hours) tire
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 pres-
sure to approximately 24 psi (165 kPa). This
tire pressure is sufficiently low enough to turn
on the TPMS Warning Light. Driving the vehicle
may cause the tire pressure to rise to approxi-
mately 28 psi (193 kPa), but the TPMS Warn-
ing Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the
tires have been inflated to the vehicle’ s recom-
mended cold tire pressure value.
CAUTION!
• The TPMS has been optimized for the
original equipment tires and wheels.
CAUTION!
TPMS pressures and warnings 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
an authorized dealership to have your sen-
sor 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 Tire Pressure Monitoring Sensor .
