According ly, when the low tire pressure te ll
tale illuminates, you shou ld stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a s ig
n ificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han
dli ng and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv
e r's responsib ility to ma inta in correct tire
p ressu re, even if under- inflation has not
reached the leve l to trigger ill umination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not opera ting properly. The
TPMS mal function indicator is combined wi th
the low tire press ure telltale . When the sys
tem detects a malfunction, the te lltale will
f lash fo r approximately one minute and then
remain cont inuous ly illuminated. This se
quence will continue upon subsequen t vehicle
start -ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is ill uminat
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea
sons , includ ing the installat ion of replace
ment or a lternate tires or whee ls on the veh i
cle that prevent the TPMS from funct ioning
p roperly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your veh icle to ensure that the re
p lacement or a lternate tires and wheels allow
the TPMS to continue to function p roperly. Tire pressure indicator appears

low or if there is a system malfunction .

If the pressure decreases in one
or more t ires, this is indicated in the instru
