Declaration according to NHTSA/

FMVSS 138 Tire Pressure Monitoring

Systems

Each tire, including the spare, should be

checked monthly when cold and inflated to the

inflation pressure recommended by the vehicle

manufacturer on the vehicle placard or tire infla-

tion pressure label. If your vehicle has tires of a

different size than the size indicated on the

vehicle placard or tire inflation pressure label,

you should determine the proper tire inflation

pressure for those tires. As an added safety fea-

ture, your vehicle has been equipped with a tire

pressure monitoring system TPMS that illumi-

nates a low tire pressure indicator lamp when

one or more of your tires are significantly

under-inflated. Accordingly, when the low tire

pressure indicator lamp comes on, you should

stop and check your tires as soon as possible,

and inflate them to the proper pressure. Driving

on a significantly under-inflated tire causes the

tire to overheat and can lead to tire failure.

Underinflation also reduces fuel efficiency and

tire tread life, and may affect the vehicle's han-

dling and stopping ability. Please note that the

TPMS is not a substitute for proper tire mainte-

nance, and it is the driver's responsibility to

maintain correct tire pressure, even if underin-

flation has not reached the level to trigger illumi-

nation of the TPMS low tire pressure indicator

lamp.

The TPMS malfunction indicator is combined

with the low tire pressure indicator lamp. When

the system detects a malfunction, the indicator

lamp will flash for approximately one minute and

then remain continuously lit. This sequence will

continue upon subsequent vehicle startups as

long as the malfunction exists. When the mal-

function indicator is illuminated, the system

may not be able to detect or signal low tire pres-

sure 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 indicator lamp after replac-

ing 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 func-

tion properly.
