When Driving
Tire Pressure Monitoring System
CAUTION
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 di erent 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 e ciency and
tire tread life, and may a ect 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 the
system 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.
To avoid false readings, the system samples for a little while before indicating a problem.
As a result it will not instantaneously register a rapid tire de ation or blow out.
