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-
sure labelon the inside ofthe fuel fillerflap. If
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

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

Your vehicle hasalso been equipped witha
TPMS malfunction indicator toindicate when
