When Driving

Tire Pressure Monitoring System

CAUTION

¾

  Each tire, including the spare (if provided), should be checked monthly when cold and 

infl ated to the infl ation pressure recommended by the vehicle manufacturer on the vehicle 
placard or tire infl ation pressure label. (If your vehicle has tires of a diff erent size than the 
size indicated on the vehicle placard or tire infl ation pressure label, you should determine 
the proper tire infl ation pressure for those tires.)

  As an added safety feature, your vehicle has been equipped with a tire pressure monitoring 

system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires 
is signifi cantly under-infl ated. Accordingly, when the low tire pressure telltale illuminates, 
you should stop and check your tires as soon as possible, and infl ate them to the proper 
pressure. Driving on a signifi cantly under-infl ated tire causes the tire to overheat and can 
lead to tire failure. Under-infl ation also reduces fuel effi

  ciency and tire tread life, and may 

aff ect the vehicle's handling and stopping ability.

  Please note that the TPMS is not a substitute for proper tire maintenance, and it is the 

driver's responsibility to maintain correct tire pressure, even if under-infl ation has not 
reached the level to trigger illumination of the TPMS low tire pressure telltale.

  Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when 

the system is not operating properly. 

  The TPMS malfunction indicator is combined with the low tire pressure telltale. When the 

system detects a malfunction, the telltale will fl ash for approximately one minute and then 
remain continuously illuminated. This sequence will continue upon subsequent vehicle 
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, 
the system may not be able to detect or signal low tire pressure as intended. TPMS 
malfunctions may occur for a variety of reasons, including the installation of replacement 
or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. 
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on 
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to 
continue to function properly.

  To avoid false readings, the system samples for a little while before indicating a problem. As 

a result it will not instantaneously register a rapid tire defl ation or blow out.
