Tirepressure monitoring system
Function ofthe tire pressure monitoring sys‐tem
\nDANGERRisk of accident duetoincor‐rect tire pressure
Every tire, includingthe spare (if provided),should bechecked when cold at least once amonth and inflatedtothe pressurerecom‐mendedbythevehicle manufacturer (seeTireand Loading Information placard ontheB-pillar onthe driver’sside orthe tire pres‐sure label onthe inside ofthe fuelfillerflapofyourvehicle). Ifyourvehicle has tires of adifferent sizethanthe size indicated ontheTireand Loading Information placard orthe
tire pressuretable,you needtodeterminethe proper tire pressureforthose tires.
As an added safetyfeature,yourvehicle hasbeen equipped with a tire pressure monitor‐ing system (TPMS)that illuminates a low tirepressure indicator lamp when one or more ofyour tires are significantly underinflated.Accordingly, ifthe low tire pressure indicatorlamp lights up,you shouldstop andcheckyour tires as soon as possible, and inflatethemtothe proper pressure. Driving on asignificantlyunderinflated tire causesthe tiretooverheat and can leadtotirefailure.Underinflation also increases fuel consump‐tion andreduces tire tread life, and mayaffectthevehicle's handling and braking abil‐ity. Please notethatthe TPMS is not a substi‐tutefor proper tire maintenance, and it isthedriver'sresponsibilitytomaintain correct tirepressure,even if underinflation has notreachedthe leveltotrigger illumination ofthe TPMS low tire pressure indicator lamp.
Yourvehicle has also been equipped with aTPMS malfunction indicatortoindicate when
the system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure indicator lamp. Whenthe system detects a malfunction,the indica‐tor lamp willflashfor approximatelya minuteandthenremain continuously illuminated.This sequence will continue upon subsequentvehiclestart-ups as long asthe malfunctionexists.
Whenthe malfunction indicator is illumina‐ted,the system may not be abletodetect orsignal low tire pressure as intended. TPMSmalfunctions may occurfor avariety ofrea‐sons, includingthe installation of incompati‐blereplacement or alternate tires or wheelsonthevehiclethat preventthe TPMS fromfunctioning properly.
Alwayscheckthe TPMS malfunctionwarninglamp afterreplacing one or more tires orwheels onyourvehicletoensurethatthereplacement or alternate tires and wheelsallowthe TPMStocontinuetofunction prop‐erly.
