Dodge DURANGO 2018 User Manual page 96

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
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 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 Tire Pressure Monitoring Telltale Light to be
turned off.
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.
The system will automatically update and the
Tire Pressure Monitoring Telltale Light will ex-
tinguish once the updated tire pressures have
been received. The vehicle may need to be
driven for up to 20 minutes 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 Tire Pressure Monitoring Telltale Light.
Driving the vehicle may cause the tire pressure
to rise to approximately 28 psi (193 kPa), but
the Tire Pressure Monitoring Telltale Light will
still be on. In this situation, the Tire Pressure
Monitoring Telltale Light will turn off only after
the tires have been inflated to the vehicle's
recommended cold tire pressure value.
CAUTION!
• The TPMS has been optimized for the
original equipment tires and wheels.
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. After
using an aftermarket tire sealant it is rec-
ommended 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 dam-
age the Tire Pressure Monitoring 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.
