Important safety notes
GWARNING
Each tire ,including the spar e(ifprovided),
shoul dbec hecked at leas tonce amonth
when col dand inflate dtothe pressure rec-
ommended by the vehicl emanufacturer on
the Tire and Loading Informatio nplacard on
the driver's door B-pillar or the tire pressure
labe lont he insid eofthe fuel fille rflap. If your
vehicl ehastire sofad ifferent size thant he
size indicated on the Tire and Loading Infor-
matio nplacard or the tire pressure label, you
shoul ddetermine the prope rtire pressure for
thos etires.
As an adde dsafety feature, your vehicl ehas
been equipped with atire pressure monitoring
system (TPMS )thati llum inate salowtire pres-
sure telltale when one or mor eofyourtires
ar es ignificantl yunderinflated .Accordingly,
when the lo wtire pressure telltale illuminates,
yo us houl dstop and check your tire sassoon
as possible, and inflate themtot he proper
pressure. Driving on asignificantl yunderin-
flated tire causes the tire to overheat and can lead to tire failure. Underinflatio nalso
reduce sfue lefficiency and tire trea dlife, and
maya ffect the vehicle's handling and stop-
ping ability.
Please note thatt he TPMS is notasubst itute
for prope rt

intenance ,and it is the driv-
er' sresponsibility to maintain correct tire
pressure, eve nifunderinflatio nhasnot
reachedt he level to triggeri llumination of the
TPMS lo wtire pressure telltale.
Your vehicl ehasalso been equipped with a
TPMS malfunctio nindicator to indicate if the
system is not operating properly .The TPMS
malfunctio nindicator is combine dwitht he
lo wt ire pressure telltale .Whent he system
detects amalfunction, the warning lamp will
flash for approximately aminute and then
remai ncontinuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists.
When the malfunctio nindicator is illuminated,
the system mayn ot be able to detect or signal
lo wt ire pressure as intended. TPMS malfunc-
tions mayo ccurfor av ariety of reasons,
including the installatio nofincompatible

tioning properly .Alway scheck the TPMS mal-

erly.
It is the driver's responsibility to set the tire
pressure to thatr ecommendedfor col dtires
which is suitabl efor the operating situation
(
Ypage 263).N ote thatthe correct tire pressure
for the current operating situatio nmustfirst be
taught-i ntothe tire pressure monitor. If asub-
stantia llos sofp ressure occurs, the warning
threshold for the warning message is aligned to
the taught-i nreference values. Restart the tire
pressure monitor after adjusting the pressure of
the col dtires(
Ypage 270). The current pres-
sures ar esaved as new reference values. As a
result, awarning message will appear if the tire
pressure drops significantly.
The tire pressure monitor does not warn yo uof
an incorrectly set tire pressure. Observe the
note sont he recommende dtire pressure
(
Ypage 263).
The tire pressure monitor is not able to warn you
of as udde nlossofp ressure, e.g .ifthe tire is
penetrated by aforeign object. In the event of a
sudden loss of pressure, bring the vehicl etoa
halt by braking carefully. Avoi dabrup tsteering
movements.
