Declaration according to NHTSA/

FMVSS 138 Tire Pressure Monitoring

Systems

Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la‐
bel, you should determine the proper tire infla‐
tion 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 pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi‐
ciency and tire tread life, and may affect the ve‐
hicle's handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re‐
sponsibility to maintain correct tire pressure,

even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres‐
sure 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 flash for approxi‐
mately one minute and then remain continu‐
ously 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 in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement 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 re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
