Introduction
NOTE
USA – FCC ID: KR5S122780002 This device complies with part 15 of the FCC rules. Operation is subject to the fol-lowing conditions: (1) This device may notcause harmful interference, and (2) thisdevice must accept any interferencereceived, including interference that maycause undesired operation.
The tire pressure monitoring system1
uses
sensors mounted in the tire valves to check inflation pressure levels. When the vehicle ismoving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmitinflation pressure data to a receiver located inthe vehicle. When low inflation pressure is detected or if a sensor is not functioning properly, TPMS will light up the tire pressure warning light (
)
(also referred to as a telltale) in the instrument panel and will display one of the following messages in the text window:
Tire pressure
low or
Tire needs air now.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and
Tire press. syst Service
required will be displayed.
Each tire, including the spare 2
(if provided),
should be checked monthly when cold and inflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor-ing system (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illu-minates, you should stop and check yourtires as soon as possible, and inflate them tothe proper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheatand can lead to tire failure. Under-inflationalso reduces fuel efficiency and tire tread life, and may affect the vehicle's handling andstopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists. When the malfunction indicator is illu-minated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioningproperly. Always check the TPMS malfunc-tion telltale after replacing one or more tiresor wheels on your vehicle to ensure that the
