Important safety notes
GWARNING
Eac htire, includin gthe spar e(if provided),
should be checke datleast once amonth
when cold and inflated to th epressur erec-
ommended by th evehicl emanufacturer on
th eT irea nd Loading Information placard on
th ed river' sdoor B-pillar or th etirep ressur e
label on th einside of th efuel filler flap .Ifyour
vehicl ehas tires of adifferen tsizet hant he
siz eindicated on th eTirea nd Loading Infor -
mation placard or th etirep ressur elabel, you
should determine th eproper tire pressur efor
those tires .
As an added safet yfeature, your vehicl ehas
been equipped wit hatirep ressur emonitoring
system (TPMS) that illuminate salow tire pres-
sur etelltale when on eormoreofy our tires
are significantly underinflated. Accordingly,
when th elow tire pressur etelltale illuminates,
you should stop and chec kyour tires as soo n
as possible ,and inflat ethemtot heproper
pressure. Drivin gonasignificantly underin-
flated tire causes th etiretoo verheat and can
lead to tire failure. Underinflation also
reduce sfuel efficiency and tire tread life ,and
may affec tthe vehicle's handlin gand stop-
pin gability.
Pleas enotet hatthe TPM Sisn otas ubstitut e
for proper tire maintenance ,and it is th edriv-
er' sre
sponsibilit ytom aintai ncorrect tire
pressure, eve nifunderinflation has no t
reached th elevel to trigge rillumination of th e
TPM Slow tire pressur etelltale.
Your vehicl ehas also been equipped wit ha
TPM Smalfunction indicator to indicat eifthe
system is no toperating properly. The TPM S
malfunction indicator is combined wit hthe
low tire pressur etelltale. When th esystem
detects amalfunction ,the warning lamp will
flas hfor approximately aminute and then
remain continuously illuminated. This
sequenc ewill be repeated every time th evehi-
cle is started as lon gasthemalfunction
exists.
When th emalfunction indicator is illuminated,
th es ystem may no tbeable to detec torsignal

tion smay occur for avariet yofr easons,
includin gthe installation of incompatible
replacemen toralternate tires or wheels on

It is th edriver' sresponsibilit ytos et th etire
pressur etothatrecommended for cold tires
whic hiss uitable for th eoperating situation
(
Ypage 258). Not etha tthe correc ttirep ressur e
for th ecurren toperating situation must first be
taught-in to th etirep ressur emonitor. If there is
as ubstantial loss of pressure, th ewarning
threshold for th ewarning message is aligned to
th er eferenc evalue staught-in .Restart th etire
pressur emonitor after adjusting th epressur eof
th ec oldt ires (
Ypage 264). The curren tpres-
sures are saved as ne wreferenc evalues. As a
result ,awarning message will appear if th etire
pressur edrops sign ifica
ntly.
The tire pressur emonitor does no twarn you of
an incorrectl yset tire pressure. Observ ethe
note sont herecommended tire pressur e
(
Ypage 258).
The tire pressur emonitor is no table to warn you
of as udde nloss of pressure, e.g. if th etirei s
penetrated by aforeign object. In th eevent of a
sudde nloss of pressure, brin gthe vehicl etoa
halt by braking carefully. Avoid abrup tsteering
movements.
The tire pressur emonitor has ayellow warning
lamp in th einstrumen tcluste rfor indicating
pressur eloss or amalfunction .Whether th e
warning lamp flashes or lights up indicates
whether atirep ressur eistoolow or th etire
pressur emonitor is malfunctioning :
Rif thewarning lamp is lit continuously, th etire
pressur eononeor mor etires is significantly

functioning .
Rif thewarning lamp flashes for aroun da
minute and then remain slit constantly, th e
tire pressur emonitor is malfunctioning .

In addition to the warning lamp,amessage
appears in the multifunction display. Observe
the information on display messages
(
Ypage 196).
It may take up to ten minutes for amalfunction
of the tire pressure monitor to be indicated .A
malfunction wil lbeindicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after afew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at agas station with apressure gauge. The
tire pressures shown by the on-board computer
refer to those measured at sea level.Ath igh
altitudes, the tire pressure values indicated by a
pressure gauge are higher than those shown by the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radi otransmit-
ting equipment (e.g. radi oheadphones, two-way
radios) that may be being operated in or near the vehicle.
Checking the tire pressure electroni-
cally
XMake sure that the SmartKey is in position 2
in the ignition lock (Ypage 115).
XPress the =or; button on the steering
wheel to select the Serv.menu.
XPress the9or: button to select
Tire Pressure.
XPress the abutton.
The current tire pressure of each tire is shown
in the multifunction display.
If the vehicle has been parked for over
20 minutes, the Tire pressure will be
displayed after driving afew minutesmessag eappears.
After ateach-in process, the tire pressure mon-
itor automatically detects new wheelsorn ew
sensors. As long as aclear allocation of the tire
pressure valu etothe individual wheel sisnot
possible, the Tire

pressure display. The tire pressures are already
being monitored.
If an emergency spare wheel is mounted, the
system may continue to show the tire pressure of the wheel that has been removed for
afew
minutes. If this occurs, note that the valu edis-
played for the positionw here the spare wheel is
mounted is not the same as the current tire
pressure of the emergency spare wheel.
Tire pressure monitor warning mes-
sages
If the tire pressure monitor detects apressure
loss in one or more tires, awarning messag eis
shown in the multifunction display. The yellow
tire pressure warning lamp then lights up.
RIf the Please Correct Tire Pressuremessag eappears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the
opportunity arises.
RIf the Check Tiresmessag eappears in the
multifunction display, the tire pressure in at
least one tire has droppeds ignificantly. The
tires must be checked.
RIf the WarningTireMalfunctionmessage
appears in the multifunction display, the tire
pressure in at least one tire has droppeds ud-
denly.T he tires must be checked.
Observe the instructions and safety notes in the
display messages in the "Tires" section
(
Ypage 196).
If the wheel positions on the vehicle are rotated,
the tire pressures may be displaye dfor the
wrong positions for ashort time. This is rectified
after afew minutes of driving, and the tire pres-
sures are displaye dfor the correct positions.
Restarting the tire pressure monitor
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp sgoout. The monitor uses the cur-
rently set tire pressures as the reference values for monitoring. In most cases, the tire pressure
monitor wil lautomatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can also define refer-
ence values manually as describedh ere. The tire
pressure monitor then monitors the new tire
pressure values.
XSet the tire pressure to the valu erecommen-
ded for the corresponding driving situation on
the Tire and Loading Information placard on
the driver's side B-pillar(
