The system has detected a wheel change, but
has not yet been reset. It is not possible to pro-
vide a reliable warning about the current infla-
tion pressure.
Check the tire inflation pressure and reset the
system, page 76.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the vehi-
cle placard or tire inflation pressure label, you
should determine the proper tire inflation pres-
sure for those tires. As an added safety feature,
your vehicle has been equipped with a tire pres-
sure monitoring system TPMS that illuminates a
low tire pressure telltal e when one or more of
your tires are significantly underinflated.
Accordingly, when the low tire pressure telltale
illuminates, you should st op and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is the
driver's responsibility to
maintain correct tire
pressure, even if underi nflation has not reached
the level at which the TPMS low tire pressure tell-
tale illuminates.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue
upon subsequent vehicle startups as long as the
malfunction exists. When the malfunction indi-
cator is illuminated, the system may not be able
to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning prop-
erly. Always check the TP MS malfunction telltale
after replacing one or mo re tires or wheels on
your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.
