Yellow Indicator Lights - Jeep Wrangler 2018 User Manual

the TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.
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 opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
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 your authorized dealer to have your
sensor function checked.
The system only warns the tire pressure is
low: it is not able to inflate them.
