Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper- age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
!Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Only use fuses marked with an "S". Other-
wise, components or systems could be dam-
aged.
!Make sure that no moisture can enter the
fuse box when the cover is open.
!When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions stop
operating.
Blown fuses must be replaced with fuses of the same rating, which you can recognize by the
color and value. The fuse ratings are listed in the
fuse allocation chart.
The fuse allocation chart is in the fuse box in the
front-passenger footwell (
Ypage 298).
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified special-
ist workshop, e.g. an authorized Mercedes-Benz
Center.
Before changing a fuse
XSecure the vehicle against rolling away
(Ypage 143).
XSwitch off all electrical consumers.
XVehicles without KEYLESS-GO: remove the
SmartKey from the ignition lock.
XVehicles with KEYLESS-GO start-function
or KEYLESS-GO: open the driver's door.
The vehicle electronics are now in position
g. This is the same as the SmartKey being
removed from the ignition.
The fuses are located in various fuse boxes:

Operation299
Wheels and tires
Z

Check wheels and tires for damage at least once
a month. Check wheels and tires afterdriving
off-road or on rough roads. Damaged wheels
can cause a loss of tire pressure. Pay particular
attention to damage such as:
RCuts inthe tires
RPunctures inthe tires
RTears inthe tires
RBulges on tires
RDeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 300). Ifnecessary, turn the
front wheels to full lock inorder to inspect the
inner sideof the tire surface.
All wheels must have a valve cap to protect the valve against dirtand moisture. Do not mount
anything onto the valve other than the standard
valve cap or other valve caps approved by
Mercedes-Benz for your veh icle. Do not use any
other valve caps or systems, e.g. tire pressure
monitoring systems.
Regularly check the pressure of all the tires par-
ticularly prior to long tr ips.Adjust the tire pres-
sure as necessary (
Ypage 302).
Observe the notes on the emergency spare
wheel (
Ypage 323).
The service lifeof tires depends, among other
things, on the foll owing factors:
RDrivin g style
RTire pressure
RDistance covered
Notes on tire tread
GWAR NING
In suff icient tire tread willreduce tire traction.
The tire isno longer abletodissipat e water.
This means that on wet road surfaces, the risk
of hydroplaning increases, inparticular where
speed isnot adapted to suit the driving con-
dit ions. There isa risk of acc ident.
If the tire pressure istoo high or too low,tires
may exhibit diff erent levelsof wear at differ-
ent locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
widt h of all tires.
Minimum tire tread depth for:
RSummer tires: âin(3 mm)
RM+S tires: ãin(4 mm)
For safety reasons, replace the tires before
the legally prescribe d limit for the minimum
tire tread depth is reached.
Marking :shows where bar indicator ;for
tread wear is integrated into the tire tread.
Treadwear indicators (TWI) are required bylaw.
Six indicators are positioned on the tire tread.
They are vis ibleonce a tread depth of approx-
imately áin(1.6 mm) has been reached. Ifthis
is the case, the tire isso worn that it must be
replace d.
Selecting, mounting and replacing
tires
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load rating and speed rating required for
your vehicle.
ROnly mount tires and wheels of the same type
and make.
Exception: itis permissible to install a differ-
ent type or make inthe event of a flat tire.
Observe here the "MOExtended tires (tires
300Operation
Wheels and tires

with run-flat characteristics)" section
(Ypage 284).
ROnly mount tires of the correct size onto the
wheels.
RBreak in new tires at moderate speeds for the
first 60 miles(100km). Th ene w tires only
reach their full performance after this dis-
tance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
RReplace the tires after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (
Ypage 323).
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 activated tire pressure loss warning
system (Canada only) or tire pressure monitor
(USA only) and only on wheels specifically tes-
ted by Mercedes-Benz.
Notes on driving with MOExtended tires with a
flat tire (
Ypage 284).
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 may be obtained from
a qualified specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (
Ypage 319).
Driving with summer tires
At temperatures below 45 ‡ (+7 †),summer
tire slose el asticity 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.
GWARNING
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
GWARNING
M+S tires with a tire tread depth of less than
ã in(4 mm ) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both types of tire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tires will allow driving safety systems
such as ABS and ESP
®to function optimally in
winter. These tires have been developed specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Winter operation301
Wheels and tires
Z

When you have mounted the M+S tires:
XCheck the tire pressures (Ypage 302).
XRestart the tire pressure monitor (USA only)
(Ypage 309).
XRestart the tire pressure loss warning system
(Canada) (Ypage 306)
Snow chains
GWARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abrasion
to the vehicle body or to chassis components.
This could cause damage to the vehicle or the
tires. There is a risk of an accident.
To avoid hazardous situations:
Rnever mount snow chains on the rear
wheels
Ronly mount snow chains in pairs on the
front wheels.
!On some tire sizes there is not enough space
for snow chains. To avoid damage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" 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 a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
If you intend to mount snow chains, please bear
the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations (
Ypage 323).
ROnly 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.
RLocal regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
RNever use Parking Pilot when snow chains are
installed (Ypage 173). You may wish to deactivate ESP
®when pulling
away with snow chains installed . You can
thereby allow the wheels to spin in a controlled
manner, achieving an increased driving force
(cutting action).

Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe 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:
