50 0k Pa(5 bar/73 psi).
Do not switch off th etirei nflation com-
pressor during this phase.
X Let th etirei nflation compressor run fo ra
maximum of te nminutes. The tire should
then hav eattained apressur eofatl east
18 0k Pa (1.8 ba r/26psi).
Switch the tire inflation compressor off
briefly to read the correct value from pres- sure gauge 0084.
! Do not operate the tire inflation compres-
sor for longe rthan ten minute satatime
without abreak. It may otherwise overheat.
The tire inflation compressor can be oper-
ated again once it has coole ddown.
Tire pressure of at leas t180 kPa
(1.8 bar/2 6psi) is not reached If, after five minutes,
apressure of 180 kPa
(1.8 bar/26 psi )has not bee nachieved: X
Switch off the tire inflation compressor,
remove it and drive the vehicle approx-
imately 30 ft (10 m) forward or back.
Thi sd istributes the TIREFIT more evenly.
X Leave tire sealant bottle 0043attache dtothe

X Pump up the tire again. G
WARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and atire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.

Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is arisk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle by Mercedes-Benz, or are of acorresponding
standard of quality.
R You may not attach snow chains to all
wheel-tire combination ,see the informa-
tion under "Wheels and tires" in the "Tech-
nical data" section.
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi- ble when you come to aroad that is not
snow-covered.
R Local regulations may restrictt he use of
snow chains. Observe the appropriate reg- ulations if you wish to mount snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
i You can deactivate ESP ®
(Y page 55)
when pulling away with snow chains instal-
led. You can thereby allow the wheels to
spin in acontrolled manner, achieving an
increased driving force (cuttinga ction). Tire pressure

Important safety notes G
WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
R monthly, at least
R if the load changes
R before beginning along journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.

Loading Information placard and tire pres-
sure tables are examples. Tire pressure
specifications are vehicle-specific and may
deviate from the data shown here. The tire pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure table on the vehicle.

mounted at the factory can be found on the
labels described here.

Important safety notes G
WARNING
Each tire, including the spare (if provided),
should be checked at least once every two
weeks when cold and inflated to the pressure recommended by the vehicl emanufacturer
on the Tire and Loading Information placard
on the driver' sdoor B-pillar or the tire pres-
sure label on the inside of the fuel filler flap .If
yourv ehiclehas tires of adifferent size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label, you should determine the
prope rtire pressure for those tires.
As an added safety feature ,you rv ehicl ehas
been equippe dwithatire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sure telltal ewhen one or more of yourt ires
are significantly underinflated. Accordingly,
when the low tire pressure telltal elights up,
you should stop and check yourt ires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire cause sthe tire to overhea tand can
leadtot ire failure. Underinflation alsor
educes fuel efficiency
and tire tread life ,and may affect the vehicle's
handling and stopping ability .Please note that
the TPMS is not asubstitute for prope rtire
maintenance, and it is the driver' sresponsi-
bility to maintai ncorrect tire pressure, even if
underinflation has not reache dthe level to
trigger illumination of the TPMS low tire pres-
sure telltale.
Yourv ehiclehas alsob een equippe dwith a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the sys-
tem detects amalfunction, the warning lamp
willf lashf or approximatel yaminute and then
remai ncontinuously illuminated. This
sequence willber epeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be abletod etect
or signa llow tire pressure as intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of incom-
patible replacement or alternate tires or
wheels on the vehicl ethat prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltal eafter replacing one
or more tires or wheels on yourv ehicleto
ensure that the replacement or alternate Tires
and wheels allow the TPMS to continue to
function properly.
It is the driver' sresponsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(Y page2 53).Note that the correct tire pres-
sure for the current operating situation must
first be taught-in to the tire pressure monitor.
If there is asubstantial loss of pressure, the
warning threshol dfor the warning message is
aligned to the reference values taught-in.
Restart the tire pressure monitor after adjust-
ing the pressure of the cold tires
(Y page2 59).The current pressures are
saved as new reference values. As aresult, a Tire pressure
