for important lire safety warnings.
The
text on
this
page
is
a
legislative requirement
by
the
Fede6l authorities:
Each tire,
including
the spare
(if
provided
),
should be
checked
monlhlywhen
cold and in{lated to the inflation pressure recom-
mended
by the
vehicle manufacturcr
on
lhe vehicle
placard
or
li€
iniation
pressurclabea.
(lfyoutvehicle
haslnes ofa
diferent
sizethan
lhe
size
indicated
on
the vehicle placard
ortirc
inflation
pressure label, you should
detemine the
prcper
tire iniation
pressu.e
ior
those
tires.)
As an added safety
featurc, yourvehicle
has been equipped
with
a tire
prcssure moniioring syslem
(TPMS)
that illuminales
a
low
tire pressure to,ltale when one or
morc
ofyour
tircs
is
sig-
nificantly
undecinfated-
Accordingly, when the
low tire
pressure
telft€le illuminates,
you
should
stop and
chsckyourti€s
as
soon
as possible, and inflate them to
ihe
proper
pressure.
Driving
on a
signitcantly undeFinflated
tire causes
ihe
tire to
overheal
and can lead
to
lire
failure.
Under-inflation also reduces fuel
ef-
fciency
and tire tread life, and may
affect
lhe vehicle's handling
and stopping
ability.
Please note that the
TP^,S
is not a substituie
for
properlire
maintenance, and
it
islhe
d
ver's responsibility to mainta;n
c.r-
rect
lire prcssure, even
if

reached

Yourvehicle
has also been
equipped
with
a
TPMS malfunction
indicalorto
indicate when
the syslem is
not
operating prope
y.
The
TP[/S
malfunction indicator is combined with the low
tire
prcssurc
telltale.
When
the
system detects
a
malfunciion,
the
telltale
williash
for
approximately
one minute and
then

continuously

sequence
will
continue
upon
subsequenl
vehicle
start-ups as long as
the
malfunction exisls.
When

is
illuminated,
the
system
may
not
be
able to deiecl or
signallowlirc

intended.
TPMS
malfuncljons may
occur
for
a
variety of
reasons, including the
inslallation of replacement or alternate tires or wheels on
the
vehicle lhat prevent
the
TPMS
from
functioning properly- Always
check
the
TPI\,,|S
malfunctaon
telltale after rep,acing one
or
more
tires
orwheels
on
your
vehicle
10
ensue
that the
replacement

TP[,4S
to continug to
