Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle’s tires
and transmit tire pressure readings to
a receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and in ated to the
in ation pressure recommended by
the vehicle manufacturer on the
vehicle placard or tire in ation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire in ation pressure label, you
should determine the proper tire
in ation 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 signi cantly under-in ated.Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and in ate them to
the proper pressure. Driving on a
signi cantly under-in ated tire
causes the tire to overheat and can
lead to tire failure. Under-in ation
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-in ation
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
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 telltale. When thesystem detects a malfunction, the
telltale will ash 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.
