2016 MERCEDES-BENZ METRIS inflation pressure

Regular wheel and tire checks
GWARNING
Damaged tire scan cause tire inflation pres-
sure loss. As aresult, yo ucould lose control of
your vehicle. There is ariskofa ccident.
Check the tire sregularl yfor signs of damage
and replace any damaged tire simmediately.
Check the wheel sand tire sofyourv ehicl efor
damag eregularly, i.e .atleast every two weeks,
as well as afte rdriving off-road or on rough
roads. Damaged wheel scan cause alos soft ire
pressure. Payp articula rattention to damage
such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosio nonwheels
Regularly check the tire trea ddepth and the
condition of the trea dacross the wholew idth of
the tire (
Ypage 268). If necessary, turn the
front wheel stofullloc kino rder to inspect the
inner sid eofthe tire surface.
All wheel smusth aveav alve cap to protect the
valve against dirt and moisture. Do not install
anything onto the valve othe rthan the standard
valve cap or othe rvalve cap sapproved for your
vehicl ebyd ealers listed on the inside of the
front cover. Do not install any othe rvalve caps
or systems ,e.g. tire pressure monitor systems.
Regularly check the pressure of al lthe tires,
particularly prior to long trips. Adjust the tire
pressure if neces sary (
Ypage 270).
The service life of tire sdepends on various fac-
tors, including the following:
Rdriving style
Rtire pressure
Rmileage
Tire tread
GWARNING
Insufficient tire trea dwillr educe tire traction.
The tire is no longer able to dissipate water.
Thi sm eans that on we troa ds urfaces, the risk
of hydroplaning increases, in particula rwhere
speed is not adapted to suit the driving con-
ditions .There is ariskofa ccident.
If the tire pressure is too hig hortoo low, tires
may exhibi tdifferent level sofwearatd iffer-
ent locations on the tire tread. Thus, you
shoul dregularl ycheck the trea ddepth and
the condition of the trea dacross the entire
width of al ltires.
Minimum tire trea ddepth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons,r eplace the tiresbefore
the legall yprescribed limit for the minimum
tire trea ddepth is reached.
Marker :shows the location where the bar
indicator (arrow )for trea dwearisi ntegrated
into the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned ove rthe tire
tread. The yare visible once the trea ddepth is
approximately áin (1.6 mm). If this is the case,
the tire is so worn that it mus tbereplaced.

Wheel sand tires

Follow recommendedtire inflation pressures
and check the pressure of al lthe tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the loa dchanges
Rbefore beginning along journey
Runder different operating conditions, e.g.
off-roadd riving
If necessary ,correct the tire pressure.
GWARNING
If yo ufit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to thei rdesign, retrofitted tire pres-
sur em onitors keep the tire valve open. This
can also result in tire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve cap sapproved by Mercedes-Benz for
your vehicle onto the tire valve.
!The pressure difference between tires on
any one axl emustb enog reater than 10 kPa
(0.1 bar/1.5 psi).

Check the tire pressure regularly ,atleast
ever y14d ays.
General notes
You will find information on tire pressure for the
vehicle' sfactory-mounted tires on the plates
described here.
The recommende dtire pressure for various
operating conditions can be found on the Tire
and Loading Information placard on the B-pillar
on the driver's sid eofthe vehicle or on the tire
pressure tabl einside the fue lfiller flap. Furthe
rinformation on tire pressure can be
obtained at aquali fied specialist workshop.
Tire and Loading Informatio nplacard

Important safety notes
GWARNING
Tire valve that are not approved for you rvehi-
cle by the distributor named on the inside
cover pag emay result in aloss of tire pres-
sure .This may affect road safety .There is a
risk of an accident.
Only use tire valve that are approved for your
vehiclebyt he distributor named on the inside
cover page. Always make sure you have the
correct tire valve type for the tires on your
vehicle.
!Do not screw additiona lweights (check
valves, etc.) onto the tire valves. The elec-
tronic components coul dthus be damaged.
iFor safety reasons, Mercedes-Benz recom-
mends that you only use tire valve sthat have
been tested for use on you rvehicle.
Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, proceedasf ollows:
XRemove the valve cap of the tire you wis hto
check.
XPress the tire pressure gauge securely onto
the valve.
XRea dthe tire pressure and compare it with the
recommendedv alueont he loading informa-
tion table or the tire pressure table
(
Ypag e270).
XIf the tire pressure is too low ,increas eittothe
recommendedv alue.
XIf the tire pressure is too high ,release air by
pressing downt he metal pin in the valve .Use
the tip of apen, for example. Then, check the
tire pressure again using the tire pressure
gauge.
XScrew the valve cap onto the valve.
XRepeat the steps for the other tires.
Tire pressure monitor
General notes
In vehicles with atire pressure monitor system,
the vehicle's wheels have sensors installed
which monitor the tire pressure in all four tires.
The tire pressure monitor warns you if the pres- sure drops in one or more of the tires. The tire
pressure monitor only functions if the corre-
sponding sensors are installed on all wheels.
Tire pressure display (only on vehicles with steer-
ing whee lbuttons)
On vehicles with steering whee lbuttons, the
current pressure of the individua ltires in the
display can be shownv ia theService
menu.

Important safety notes
GWARNING
Each tire, including the spare (ifp rovided),
should be checked at least once amonth
whe ncold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tir eand Loading Information placard on
the driver's doo rB-pilla rort he tire pressure
label on the inside of the fue lfiller flap. If your
vehicle has tires of adifferent size than the
size indicated on the Tir eand Loading Infor-
mation placard or the tire pressure label ,you
should determine the proper tire pressure for
those tires.
As an added safety feature ,you rv ehicle has
bee nequipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sur etelltal ewheno ne or more of your tires
are significantly underinflated. Accordingly,
whe nthe low tire pressure telltal eillumi nates,
yo us hould stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire causes the tire to overheata nd can
lea dtot ire failure. Underinflation also
reduce sfue lefficiency and tire treadl ife, and
may affect the vehicle' shandling and stop-
ping ability.
Please note that the TPMSisn otas ubstitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMSl ow tire pressure telltale.
USA only:
You rvehicle has also bee
nequipped with a
TPM

Sm alfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. Whe nthe system
detects amalfunction, the warning lamp will
flash for approximately aminute and then
remain continuously illuminated. This
sequence will be repeated ever ytime the vehi-
cle is starte daslong as the malfunction
exists.
Whe nthe malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMSm alfunc-
tions may occur for avariety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMSf rom func-
tioning properly. Alway scheck the TPMSm al-
function telltal eafterreplacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMStoc ontinuetofunction prop-
erly.
It is the driver's responsibility to set the tire
pressure to the recommende dcold tire pressure
suitabl efor the operating conditions
(
Ypage 270).
Note that the correct tire pressure for the cur-
rent operating conditions mus tfirs tb ep ro-
gramed into the tire pressure monitor. If there is
as ubstantial los sofpressure, the warning
threshol dfor the warning messag eisaligne dto
the reference value sprograme din. Restart the
tire pressure monito rafte radjusting the cold
tire pressure (
Ypage 277). The current pres-
sures are saved as new reference values. This
will ensure that awarning messag ewillo nly
appea rifthe tire pressure drop ssignificantly.
The tire pressure monito rdoesn ot warn yo uifa
