DANG ER Risk of accident due toincor‐
re ct tire pressure
Every tire, including the spare (if pr ovided),
should be checked when cold at least once a
month and inflated tothe pressure recom‐
mended bytheve hicle manufacturer (see
Ti re and Loading Info rmation placard on the
B-pillar on the driver ’sside or the tire pres‐
sure label on the inside of the fuel filler flap
of your vehicle). If your vehicle has tires of a
dif fere nt size than the size indicated on the
Ti re and Loading Info rmation placard or the
tire pressure table, you need todeterm ine
th e proper tire pressure forth ose tires.
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐
ing sy stem (TPMS) that illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are signif icantly underinflated.
Ac cording ly, if the low tire pressure indicator
lamp lights up, you should stop and check
yo ur tires as soon as possible, and inflate
th em tothe proper pressure. Driving on a
significant lyunderinflated tire causes the tire
to ov erheat and can lead totire failure.
Un derinflation also increases fuel consump‐
tion and reduces tire tread life, and may
af fect theve hicle's handling and braking abil‐
ity. Please no tethat the TPMS is not a substi‐
tute for proper tire maintenance, and it is the
driver's responsibility tomaintain cor rect tire
pressure, even if underinflation has not
re ached the le velto trig ger illumination of
th e TPMS low tire pressure indicator lamp.
Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate whenthe sy stem is not operating proper ly. The
TPMS malfunction indica tor is combined with
th e low tire pressure indicator lamp. When
th e sy stem de tects a malfunction, the indica‐
to r lamp will flash for app roxima tely a minute
and then remain continuously illumina ted.
This sequence will continue upon subsequent
ve hicle start-ups as long as the malfunction
ex ists.
When the malfunction indicator is illumina‐
te d, the sy stem may not be able todetect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variet yof rea‐
sons, including the ins tallation of incompati‐
ble replacement or alternate tires or wheels
on theve hicle that pr eventthe TPMS from
functioning properly.
Alw aysch eck the TPMS malfunction warning
lamp af terre placing one or more tires or
wheels on your vehicle toensure that the
re placement or alternate tires and wheels
allow the TPMS tocontinue tofunction prop‐
erly.
