WARNING
Each tire,includi ngthe spare (ifprovide d),
shoul dbe checked atlea stonce every two
weeks whencoldandinflated tothe pressu re
recommended bythe vehicle manufacture r
on the Tire andLoadi ngInformation placard
on the driver's doorB-pilla ror the tire pres-

you rvehicle hastires ofadifferent sizethan
the size indicated onthe Tire andLoadi ng
Information placard or,ifavai lable,the tire
pressu relab el,you shoul ddetermine the
proper tirepressu refor those tires.
As anadde dsafety feature, yourvehicle has
been equipped withatire pressu remonitoring
system (TPMS)thatilluminates alow tirepres-
sure telltal ewhen oneormore ofyou rtires

when thelow tirepressu retelltal elights up,
you shoul dstop andcheck yourtires assoon
as possib le,and inflate themtothe proper
pressu re.Driving onasignifica ntlyunderin-
flated tirecause sthe tire tooverhea tand can
lea dto tire failure.
Underinfla tionalso reduces fuelefficiency
and tiretread life,and may affect thevehicle 's
handli ngand stopping ability. Plea senote that
the TPMS isnot asubstitu tefor proper tire
maintenance, anditis the driver's responsi-
bili tyto maintain correcttirepressu re,even if underinfla
tionhasnotreached thelevel to
trigger illuminatio nof the TPMS lowtirepres-
sure telltal e.
Your vehicle hasalso been equipped witha
TPMS malfunction indicator toindicate when
the system isnot opera tingproperl y.The
TPMS malfunction indicator iscombined with
the low tirepressu retelltal e.When thesys-
tem detects amalfu nction, thewarning lamp
wil lflash forappro ximately aminute andthen
remain continuously illuminated .This

cle isstarted aslong asthe malfu nction
exists. Whenthemalfu nction indicator isillu-
minated, thesystem maynotbeabl eto detect
or signal lowtirepressu reas intended.
TPMS malfunctions mayoccur foravariety of
reasons, includingthe installa tionofincom-
