responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level at which the low tire
pressure indicator lamp of the TPMS lights up.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure indicator lamp. When the
system detects a malfunction, the indicator
lamp will flash for approximately 1 minute and
then remain illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is lit, the system may
not be able to detect or signal low tire
pressure as intended.
i The operation of the tire pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
operated in or near the vehicle.
i This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
1.
This device may not cause harmful
interference, and
2. This device must withstand any
interference received, including
interference that may cause undesired
operation.
Unauthorized modifications to the device
could void the user’s authority to operate
the equipment.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction indicator 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.
