DANG ER Risk of accident due toincor‐
re ct tire pressure
Each tire, including the spare (if pr ovided),
should be checked monthly when cold and
inflated tothe inflation pressure recommen‐
ded bytheve hicle manufacturer on theve hi‐
cle placard or tire inflation pressure label. (If
yo ur vehicle has tires of a dif fere nt size than
th e size indicated on theve hicle placard or
tire inflation pressure label, you should de ter‐ mine
the proper tire inflation pressure for
th ose tires.)
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐
ing sy stem (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly unde r-inflated. Accord‐
ingly, when the low tire pressure telltale illu‐
minates, you should stop and check your tires
as soon as possible, and inflate them tothe
proper pressure. Driving on a significantly
under-inflated tire causes the tire toove rheat
and can lead totire failure. Under-inf lation
also reduces fuel ef ficiency and tire tread li fe,
and may af fect theve hicle's handling and
st opping ability. Please no tethat the TPMS is
not a substitute for proper tire maintenance,
and it is the driver's responsibility tomaintain

WARNING Risk of accident from tire
ove rheating and tire failure
The temp erature grade forth is tire is es tab‐
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause excessive heat
build-up and possible tire failure. #
Obser vethere commended tire pres‐
sures and regular lych eck the tire pres‐
sure of all tires including the spare
wheel. #
Adjust the tire pressure as necessar y. The
temp erature grades are A (highest grade), B
and C. These relate toa tire's resis tance toheat
and its ability torelease heat on a specified test
wheel in laboratory tests under contro lled condi‐
tions. Sus tained high temp eratures can cause the
material of the tire todegenerate and reduce tire
life. In addition, excessively high temp eratures
can lead tosudden tire failure. Grade C refers to
a per form ance which all passenger vehicle tires
must exhibit, according totheU. S. Depa rtment
of Transpor tation's requ irements. Information on DOT and TIN (Tire Identifica‐
