Important safety notes G
WARNING
Each tire, including the spare (if provided),
should be checked at least once every two
weeks when cold and inflated to the pressure recommended by the vehicl emanufacturer
on the Tire and Loading Information placard
on the driver' sdoor B-pillar or the tire pres-
sure label on the inside of the fuel filler flap .If
yourv ehiclehas tires of adifferent size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label, you should determine the
prope rtire pressure for those tires.
As an added safety feature ,you rv ehicl ehas
been equippe dwithatire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sure telltal ewhen one or more of yourt ires
are significantly underinflated. Accordingly,
when the low tire pressure telltal elights up,
you should stop and check yourt ires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire cause sthe tire to overhea tand can
leadtot ire failure. Underinflation alsor
educes fuel efficiency
and tire tread life ,and may affect the vehicle's
handling and stopping ability .Please note that
the TPMS is not asubstitute for prope rtire
maintenance, and it is the driver' sresponsi-
bility to maintai ncorrect tire pressure, even if
underinflation has not reache dthe level to
trigger illumination of the TPMS low tire pres-
sure telltale.
Yourv ehiclehas alsob een equippe dwith 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 sys-
tem detects amalfunction, the warning lamp
willf lashf or approximatel yaminute and then
remai ncontinuously illuminated. This
sequence willber epeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be abletod etect
or signa llow tire pressure as intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of incom-
patible replacement or alternate tires or
wheels on the vehicl ethat prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltal eafter replacing one
or more tires or wheels on yourv ehicleto
ensure that the replacement or alternate Tires
and wheels allow the TPMS to continue to
function properly.
It is the driver' sresponsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(Y page2 53).Note that the correct tire pres-
sure for the current operating situation must
first be taught-in to the tire pressure monitor.
If there is asubstantial loss of pressure, the
warning threshol dfor the warning message is
aligned to the reference values taught-in.
Restart the tire pressure monitor after adjust-
ing the pressure of the cold tires
(Y page2 59).The current pressures are
saved as new reference values. As aresult, a Tire pressure
