R
Break in new tires at moderate speeds for the
first 60 miles (100 km). They only reach their
full performance after this distance. R
Do not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning). R
Replace the tires after six years at the latest,
regardless of wear.
MOExtended tires (tires with run-flat
properties) With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one
or more tires.
MOExtended tires may only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor
and on wheels specifically tested by Mercedes-
Benz.
Notes on driving with MOExtended tires with a
flat tire ( Y
page 368).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit can be obtained from
a qualified specialist workshop.
Winter operation
General notes Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section ( Y
page 405).
Driving with summer tires At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehicle
to M+S tires. Using summer tires at very cold
temperatures could cause cracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. G WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires

To avoid hazardous situations: R
never install snow chains to the front
wheels R
always install snow chains in pairs to the
rear 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 a corresponding
standard of quality.
If you intend to mount snow chains, please bear
the following points in mind: R
Snow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations ( Y
page 410).R
Only use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered. R
Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains. R
Do not exceed the maximum permissible
speed of 31 mph (50 km/h). R
On vehicles with AIRMATIC ( Y
page 212) or
Magic Body Control (MBC) ( Y
page 210), you
must drive at raised vehicle level if snow
chains have been mounted. R
When snow chains are installed, never use
Active Parking Assist ( Y
page 216).
You may wish to deactivate ESP ®
when pulling
away with snow chains installed ( Y
page 74).
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv-
ing force (cutting action). 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 a risk 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 a long journey R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here are
examples. Tire pressure specifications are vehi-
cle-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 pressure table on the vehicle.
General notes The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.

Recommended tire pressures
The Tire and Loading Information placard is on
the B-pillar on the driver's side ( Y
page 394).
The Tire and Loading Information placard con-
tains the recommended tire pressures for cold
tires. The recommended tire pressures are valid
for the maximum permissible load and up to the
maximum permissible vehicle speed.
Tire pressure table The tire pressure table is on the inside of the fuel
filler flap. It shows the tire pressure for all tires
permitted at the factory for this vehicle; see
illustration (example).
The tire pressure table contains the recommen-
ded pressures for cold tires for various operat-
ing conditions, i.e. differing load and speed con-
ditions.
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid for
that tire size; see illustration (example). The load conditions "partially laden" and "fully
laden" are defined in the table for different num-
bers of occupants and amounts of luggage. The
actual number of seats may differ.
Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g. R18 .
Rim diameter is part of the tire size and can be
found on the tire sidewall ( Y
page 400).
If the tire pressures have been set to the lower
values for lighter loads and/or lower road
speeds, the pressures should be reset to the
higher values: R
if you want to drive with an increased load
and/or R
if you want to drive at higher road speeds
The tire pressures for increased loads and/or
higher road speeds, shown in the tire pressure
table, may have a negative effect on driving
comfort.
If the tire pressure is not set correctly, this can
lead to an excessive build up of heat and a sud-
den loss of pressure.

If you fit unsuitable accessories onto tire
valves, th e tire valves may be overloaded and
malfunction , whic h can caus e tire pressur e
loss . Due to their design , retrofitte d tire pres-
sur e monitors keep th e tire valv e open . This
can also result in tire pressur e loss . Ther e is a
ris k of an accident.
Only screw th e standard valv e cap or other
valv e cap s approve d by Mercedes-Ben z for
your vehicl e onto th e tire valve.
Use a suitable pressur e gauge to chec k th e tire
pressure. The outer appearanc e of a tire does
no t permit any reliable conclusio n about th e tire
pressure. On vehicles equipped wit h th e elec -
tronic tire pressur e monitor, th e tire pressur e
can be checke d in th e on-board computer.
The tire temperature and pressur e increas e
when th e vehicl e is in motion . This is dependen t
on th e driving spee d and th e load.
Therefore, you should only correc t tire pres-
sures when th e tires are cold.
The tires are cold: R
if th e vehicl e has been parked wit h th e tires
out of direct sunligh t for at least three hour s
and R
if th e vehicl e has no t been driven further than
1 mile (1. 6 km)
The tire temperature changes depending on th e
outside temperature, th e vehicl e spee d and th e
tire l oad. If th e ti
re temperature changes by
18 ‡ (10 †), th e tire pressur e changes by
approximately 10 kP a (0. 1 bar/1.5 psi) . Tak e
this int o accoun t when checkin g th e pressur e of
warm tires . Only correc t th e tire pressur e if it is to o low for th e curren t operating conditions. If
you chec k th e tire pressur e when th e tires are
warm , th e resulting value will be higher than if
th e tires were cold. This is normal. Do no t
reduce th e tire pressur e to th e value specifie d
for cold tires . The tire pressur e would otherwise
be to o low.

Information on air pressure for the tires on your
vehicle can be found: R
on the vehicle's Tire and Loading Information
placard on the B-pillar ( Y
page 394)R
in the tire pressure table in the fuel filler flap
( Y
page 189)R
in the "Tire pressure" section Checking tire pressures manually To determine and set the correct tire pressure,
proceed as follows: X
Remove the valve cap of the tire that is to be
checked. X
Press the tire pressure gage securely onto the
valve. X
Read the tire pressure and compare it to the
recommended value on the Tire and Loading
Information placard or the tire pressure table
( Y
page 387). X
If the tire pressure is too low, increase the tire
pressure to the recommended value. X
If the tire pressure is too high, release air. To
do so, press down the metal pin in the valve,
using the tip of a pen for example. Then check
the tire pressure again using the tire pressure
checker. X
Screw the valve cap onto the valve. X
Repeat these steps for the other tires.
Tire pressure monitor
General notes If a tire pressure monitor is installed, the vehi-
cle's wheels have sensors that monitor the tire
pressures in all four tires. The tire pressure mon-
itor warns you if the pressure drops in one or
more of the tires. The tire pressure monitor only
functions if the corresponding sensors are
installed in all wheels.
Information on tire pressures is displayed in the
multifunction display. After a few minutes of
driving, the current tire pressure of each tire is
shown in the Service menu of the multifunction
display; see illustration (example).

Important safety notes
G WARNIN G
Eac h tire, includin g th e spar e (if provided),
should be checke d at least once every two
week s when cold and inflated to th e pressur e
recommended by th e vehicl e manufacturer
on th e Tir e and Loading Information placard
on th e driver' s door B-pillar or th e tire pres-
sur e label on th e inside of th e fuel filler flap . If
your vehicl e has tires of a differen t siz e than
th e siz e indicated on th e Tir e and Loading
Information placard or, if available, th e tire
pressur e label, you should determine th e
proper tire pressur e for those tires .
As an added safet y feature, your vehicl e has
been equipped wit h a tire pressur e monitoring
system (TPMS) that illuminate s a low tire pres-
sur e telltale when on e or mor e of your tires
are significantly underinflated. Accordingly,
when th e low tire pressur e telltale lights up,
you should stop and chec k your tires as soo n
as possible , and inflat e them to th e proper
pressure. Drivin g on a significantly underin-
flated tire causes th e tire to overheat and can
lead to tire failure.
Underinflation also reduce s fuel efficiency
and tire tread life , and may affec t th e vehicle's
handlin g and stopping ability. Pleas e note that
th e TPM S is no t a substitut e for proper tire
mainte
nance , a nd it is th e d river' s responsi-
bilit y to maintai n correc t tire pressure, eve n if
underinflation has no t reached th e level to
trigge r illumination of th e TPM S low tire pres-
sur e telltale.
Your vehicl e has also been equipped wit h a
TPM S malfunction indicator to indicat e when
th e system is no t operating properly. The
TPM S malfunction indicator is combined wit h
th e low tire pressur e telltale. When th e sys-
te m detects a malfunction , th e warning lamp
will flas h for approximately a minute and then
remain continuously illuminated. This
sequenc e will be repeated every time th e vehi-
cle is started as lon g as th e malfunction
exists. When th e malfunction indicator is illu- minated, th e system may no t be able to detec t
or signal low tire pressur e as intended.
TPM S malfunction s may occur for a variet y of
reasons, includin g th e installation of incom-
patible replacemen t or alternate tires or
wheels on th e vehicl e that preven t th e TPM S
from functioning properly. Always chec k th e
TPM S malfunction telltale after replacing on e
or mor e tires or wheels on your vehicl e to
ensur e that th e replacemen t or alternate Tires
and wheels allow th e TPM S to continue to
function properly.
It is th e driver' s responsibilit y to set th e tire
pressur e to that recommended for cold tires
whic h is suitable for th e operating situation
( Y
page 387). Not e that th e correc t tire pressur e
for th e curren t operating situation must first be
taught-in to th e tire pressur e monitor. If there is
a substantial loss of pressure, th e warning
threshold for th e warning message is aligned to
th e referenc e value s taught-in . Restart th e tire
pressur e monitor after adjusting th e pressur e of
th e cold tires ( Y
page 392). The curren t pres-
sures are saved as ne w referenc e values. As a
result , a warning message will appear if th e tire
pressur e drops significantly.
The tire pressur e mon ito r does no t w
arn you of
an incorrectl y set tire pressure. Observ e th e
note s on th e recommended tire pressur e
( Y
page 387).
The tire pressur e monitor is no t able to warn you
of a sudde n loss of pressure, e.g. if th e tire is
penetrated by a foreign object. In th e event of a
sudde n loss of pressure, brin g th e vehicl e to a
halt by braking carefully. Avoid abrup t steering
movements.
The tire pressur e monitor has a yellow warning
lamp in th e instrumen t cluste r for indicating
pressur e loss or a malfunction . Whether th e
warning lamp flashes or lights up indicates
whether a tire pressur e is to o low or th e tire
pressur e monitor is malfunctioning :R
if th e warning lamp is lit continuously, th e tire
pressur e on on e or mor e tires is significantly
to o low. The tire pressur e monitor is no t mal-
functioning . R
if th e warning lamp flashes for aroun d a

Determining the correct load limit
Step-by-step instructions The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575 pur-
suant to the "National Traffic and Motor Vehicle
Safety Act of 1966". X
Step 1: Locate the statement "The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs." on your vehicle’s
Tire and Loading Information placard. X
Step 2: Determine the combined weight of
the driver and passengers that will be riding in
your vehicle. X
Step 3: Subtract the combined weight of the
driver and passengers from XXX kilograms or
XXX lbs. X
Step 4: The resulting figure equals the avail-
able amount of cargo and luggage load capa-
city. For example, if the "XXX" amount equals
1400 lbs an d there will be five 150-lb pas-
sengers in your vehicle, the amount of avail-Loading the vehicle 395
