Lincoln 2013 MKZ Owner's Manual page 302

Each tire, including the spare
(if provided), should be
checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label,
you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires
is significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to
tire failure. Under-inflation 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
substitute for proper tire maintenance,
and it is the driver's responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale.
Wheels and Tires
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The malfunction
indicator is combined with the low tire
pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute
and then remain continuously
illuminated. This sequence will
continue upon subsequent vehicle
start-ups as long as the malfunction
exists.
When the malfunction indicator 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 replacement or alternate tires or
wheels on the vehicle that prevent the
TPMS from functioning properly.
Always check 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.
The tire pressure monitoring system
complies with part 15 of the FCC rules
and with RSS-210 of Industry Canada.
Operation is subject to the following
two conditions: (1) This device may
not cause harmful interference, and
(2) This device must accept any
interference received, including
interference that may cause undesired
operation.
