Important safety notes
G
WARNING
Each tire ,including the spare (i fprovided),
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
pressure label on the inside of the fuel filler
flap .Ify our vehicle has tires of adifferent size
than the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label, you should determin ethe
proper tire pressure for those tires.
As an added safety feature, your vehicle has
been equipped with atire pressure monitoring
system (TPMS) that illuminates alow tire
pressure telltale when one or more of your
tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale lights up, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Drivin gona
significantly underinflated 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
handling and stopping ability. Please note that
the TPMS is not asubstitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correc ttire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure 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 detect
samalfunction, the warning
lamp will flash for approximately aminute and
then remain continuously illuminated. This
sequence will be repeated every time the
vehicle is started 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 intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of
incompatible replacement 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 replacement or
alternate Tires and wheels allow the TPMS to
continue to function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(Y page 338). Note that the correc ttire
pressure for the current operating situation
must first be taught-in to the tire pressure
monitor. If there is asubstantial loss of
pressure, the warning threshold for the
warning message is aligned to the reference
values taught-in .Restart the tire pressure
monitor after adjustin gthe pressure of the
cold tires (Y page 345). The current
pressures are saved as new reference values.
As aresult, awarning message will appear if
the tire pressure drops significantly.
The tire pressure monitor does not warn you
of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
(Y page 338).
The tire pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tire is penetrated by aforeign object. In the
event of asudden loss of pressure, bring the
vehicle to ahalt by brakin gcarefully. Avoid
sudden steering movements Check
