Maximum tire pressures
:Maximumpermitted tire pressure (example)
Never exceed the maximu mpermissible tire
inflation pressure. When adjusting the tire pres-
sure salway sobserve the recommendedt ire
pressure for you rvehicl e(
Ypage270).
iThe actua lvalues for tires are specific to
each vehiclea nd may deviate from the values
in the illustration.
Tire valve (snap-in valve)
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

Important safety notes
GWARNING
Wheel and tire dimensions as well as the type of tire can var ybetween the spare whee land
the whee ltobereplaced .Whent he spare
whee lismounted, driving characteristic smay
be severely affected. There is ariskofana cci-
dent.
In order to reduce risks:
Ryo us houl dtherefore adap tyou rd riving
style and drive carefully.
Rneve rmount more thano ne spare wheel
thatd iffer sfrom the whee ltobereplaced.
Ronlyuseaspare whee lthatd iffer sfrom the
whee ltober eplaced for ashort time.
Rdo not deactivate ESP®.
Rhave aspare whee lthatd iffer sfrom the

the neares tquali fied specialist workshop.
Yo um usto bserve the correct whee land
tire dimensions as well as the whee ltype.
Whe nusing aspare whee lofadifferent size, do
not exceed the maximump ermissibl espeed of
50 mph (80 km/h).
General notes
The procedure for mounting the spare whee lis
describe din"Mounting awheel "(Ypage 287).
The following shoul dbechecked regularly, par-
ticularly prior to long journeys:
Rthe tire pressure of the spare wheel, which
shoul dthen be corrected if necessary
(
Ypage 270).
Rthe fastenings of the spare whee lbracket.
The spare whee lislocate deither in the left rear
compartment or in aspare whee lbracket under
the vehicle.
Replace the tire safter6y ears at the latest,
regardless of wear. Thi salsoa pplies to the spare
wheel.
Vehicles with tire pressure monitor: the
spare whee lisnot equipped with asensor for
monitoring tire pressure. If yo uhavei nstalle da
spare wheel, the tire pressure monitor will not
functio nfor this wheel. The system may con-
tinu etos howt he tire pressure of the whee lthat
hasb eenr emoved for afew minutes. The value
displayed for the position where the spare wheel
is installe disnot the same as the current tire
pressure of the spare wheel.
Whe nyou are driving with the spare wheel
mounted, the tire pressure monitor canno tfunc-
tio nr eliably. Only restart the tire pressure mon-
ito rw henthe defective whee lhas been replaced
with anew whee land sensor.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print.Country-specific variation sare possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to system sand function srelevantt o
safety.
Read the information on qualified specialist
workshops (
Ypage 29).
Vehicle electronics
Tampering with the engine electron-
ics
!
Only have engin eelectronics and the corre-
spondin gparts, such as contro lunits ,actua-
tors, sensors or connector leads, serviced at a
qualified specialist workshop. Otherwise, the
vehicle parts may wear more quickly. This can
lead to loss of the New Vehicle Limited War-
ranty.
Installing electrical or electronic
equipment
You and other scan suffer health-related dam-
age through electromagnetic radiation .Byusing
an exterior antenna, apossible health risk
caused by electromagnetic fields, as discussed
in scientific circles, is taken int oaccount. Only
have the exterior antenn ainstalled by aqualified
specialist workshop.
Electrical and electronic devices may have a
detrimental effectonb oth the comfort and the
operatin gsafetyoft he vehicle. If equipment of
this kin disinstalled, its electromagnetic com-
patibility must be checked and verified.
If thes edevices are linked to function sassoci-
ated with resistance to interference, they must
have type approval. This applies to the device or
its interfaces to the vehicle electronics, e.g.
chargingb rackets.
At elephon eortwo-way radio to be installed in
the vehicle must be approved. Further informa-
tion can be found in any Mercedes-Benz Com-
mercial Van Center. For operatio
nofmobile phones and two-way
radios, Mercedes-Benz recommends connec-
tion to an approved exterior antenna. This is the
only way to ensure optimum reception quality
inside the vehicle and to minimize mutual inter-
ference between the vehicle electronics, mobile
phones and two-way radios.
The transmission output of the mobile phone or
two-way radio may not exceed the following
maximum transmission output (PEAK):
