WARNING
■ Maintenance of the tires (vehicles with the tire pressure warning sys-
tem)
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the vehi-
cle manufacturer on the vehicle placard or tire inflation pressure label (tire
and load information label). (If your vehicle has tires of a different size than
the size indicated on the vehicle placard or tire inflation pressure label [tire
and load information 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-tire pressure warning system) that illu-
minates a low tire pressure telltale (tire pressure warning light) when one or
more of your tires is significantly under-inflated. Accordingly, when the low
tire pressure telltale (tire pressure warning light) 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 effi-
ciency and tire tread life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS (tire pressure warning system) is not a substi-
tute for proper tire maintenance, and it is the driver’s responsibility to main-
tain correct tire pressure, even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale (tire pressure
warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indicate when the system is not operating
properly. The TPMS (tire pressure warning system) malfunction indicator is
combined with the low tire pressure telltale (tire pressure warning light).
When the system detects a malfunction, the telltale will flash for approxi-
mately 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 sys-
tem may not be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) 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 (tire pressure warning system)
from functioning properly. Always check the TPMS (tire pressure warning
system) malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the repl acement or alternate tires and wheels
allow the TPMS (tire pressure warning system) to continue to function prop-
erly.
