should becheck edatleast once amont h
when coldandinflated tothe pressure
recommen dedbythe vehicle manufacturer
on the Tire andLoading Informationplacard
on the driver's doorB-pillar orthe tire
pressure labelonthe inside ofthe fuel filler flap.
Ifyour vehicle hastires ofadifferent size
than thesize indicated onthe Tire andLoading
Inform ationplacard orthe tire pressure label,
you should determine theproper tirepressure
for those tires.
As anadded safetyfeature, yourvehicle has
been equipp edwith atire pressure monitorin g
system (TPMS)thatilluminates alow tire
pressure telltalewhenoneormore ofyour
tires aresignificantly underinflated.
Acc ordingly, whenthelow tirepressure
telltale illuminates, youshould stopandcheck
your tires assoon aspossible, andinflate
them tothe proper pressure. Drivingona
significantly underinflated tirecauses thetire
to overheat andcanlead totire failure.
Underinflation alsoreduces fuelefficiency
and tiretread life,and may affect thevehicle's
handling andstopping ability.
Please notethattheTPMS isnot asubstitute
for proper tiremaintenanc e,and itis the
driver's responsibility tomaintain correcttire
pressure, evenifunderinflation hasnot
reached thelevel totrigger illumination ofthe
TPMS lowtirepressure telltale.
USA only:
Your vehicle hasalso been equipp edwith a
TPMS malfunction indicatortoindicate when
the system isnot operating properly.The
TPMS malfunction indicatoriscombined with
the low tirepressure telltale.Whenthe
system detects amalfunction, thetelltale will
flash forapproximately oneminute andthen
remain continuously illuminated. This
sequence willberepeated everytimethe
vehicle isstarted aslong asthe malfunction
exists.
When themalfunction indicatorisillu minated,
the system maynotbeable todetect orsignal
low tirepressure asintended. TPMS
malfunctions mayoccur foravariety of
reasons, including theinstallation of
incompatible replacementoralternate tires
or wheels onthe vehicle thatprevent the
TPMS fromfunctioning properly. Always
check theTPMS malfunction telltaleafter Tire
