Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate if the
systemisn ot operating properly. The TPMS
malfunction indicator is combined with the
low tir epressure telltale. When the system
detects amalfunction, the warnin glamp will
flash for approximately aminut eand then
remain continuously illuminated. This
sequence will be repeated every tim ethe vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the syste mmay not be able to detec torsignal
low tir epressure as intended .TPMS malfunc-
tion smay occur for avarietyofr easons,
including the mountin gofincompatible
replacementora lternatetires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always chec kthe TPMS mal-
function telltale afte rreplacing one or more
tires or wheels on your vehicle to ensur ethat
the replacementora lternatetires and wheels
allow the TPMS to continue to function prop-
erly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Ypage 254). Notet hat the correcttirep ressure
for the current operating situation must firstb e
taught-in to the tir epressure monitor .Ifasub-
stantial loss of pressure occurs, the warning
threshold for the warnin gmessageisa ligned to
the taught-in reference values. Restar tthe tire
pressure monitor afte radjusting the pressure of
the cold tires (
Ypage 259). The current pres-
sures are saved as new reference values. As a
result,aw arningmessagew ill appear if the tire
pressure drops significan tly.
The t

ir ep ressure monitor does not warn you of
an incorrectly set tir epressure. Observe the
notes on the recommended tir epressure
(
Ypage 254).
The tir epressure monitor is not able to warn you
of as udden loss of pressure, e.g. if the tir eis
penetrate dbyaforeign object .Inthe eventofa
sudden loss of pressure, bringt he vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.
The tir epressure monitor has ayellow h
warnin glamp on the instrumentc luster for indi-cating
apressure loss or malfunction. The way
that the warnin glamp flashes or lightsupi ndi-
cates whether atirep ressure is too low or
whether the tir epressure monitor is malfunc-
tioning:
Rif the h warnin glamp is lit continuously,
the tir epressure in one or more tires is sig-
nificantly too low. The tir epressure monitor is
not malfunctioning.
Rif the h warnin glamp flashes for around a
minut eand the nremainsl it constantly, the
tir ep ressure monitor is malfunctioning.
In addition to the hwarnin glamp, amessage
appears in the multifunction display. Observe
the information on display messages
(
Ypage 183).
It may tak euptoten minutes for amalfunction
of the tir epressure monitor to be indicated. The
malfunction is indicated firstbyt heh tire
pressure warnin glamp flashingf or approx-
imately one minut eand the nremaining lit. If the
malfunction has been rectified, the htire
pressure warnin glamp goes out afte rdrivingf or
af ew minutes.
The tir epressure values indicated by the on-
board computer may differf rom those meas-
ured at agas st

ation with apressure gauge. The
tir ep ressures shown by the on-board computer
refertot hose measured at sea level. At high
altitudes, the tir epressure values indicated by a
pressure gauge are higher than those shown by
the on-board computer .Inthis case, do not
reduce the tir epressures.
The operation of the tir epressure monitor can
be affected by interference from radio transmit-
tin ge quipment( e.g. radio headphones, two-way
radios) that may be being operated in or near the
vehicle.
