Important safety notes
GWARNING
If you manipulate or bridge afaulty fuse or if
you replace it with afuse with ahigher amper-
age, the electric cables could be overloaded.
This could result in afire. There is arisk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correcta mperage.
248Fuses
Breakdown assistance

The fuses in your vehicle serve to close down
faulty circuits.Ifafuse blows, all the compo-
nentsont he 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 (
Ypage 249).
If an ewly inserted fuse also blows, have the
cause traced and rectified at aqualified special-
ist workshop, e.g. an authorized Mercedes-Benz
Center.
!Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correctf use rating for the system concerned.
Otherwise, components or systems could be
damaged.
!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.

Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly checkt he tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 252). In order to inspec tthe
inne rside of the tire surface, turn the steering
wheel to full lock.
All wheels must have avalve cap to protect the
valve against dirt and moisture. Do not install
anythin gontot he valve other than the standard
valve cap or avalve cap approved by Mercedes-
Benzf or your vehicle. Do not use any other valve
caps or systems ,e.g. tire pressure monitoring
systems.
You should regularly checkt he pressure of all
your tires includin gthe spare wheel, particularly
prior to long trips. Adjust the tire pressure as
necessary (
Ypage 254).
The servicel ife of tires depends, among other
things, on the following factors:
RDriving style
RTire pressure
RDistance covered
Notes on tir etread
GWARNING
Insufficientt ire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces,t he risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is arisk of accident.
If the tire pressure is too high or too low, tires
may exhibit differentl evels of wear at differ-
ent location sonthe tire tread. Thus, you
should regularly checkt he tread depth and
the condition of the tread across the entire
width 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 prescribed limit for the minimum
tire tread depth is reached.
Marking :shows where the bar indicator
(arrow) for tread wear is integrated int othe tire
tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread.
They are visible onc eatread depth of approx-
imately áin (1.6 mm) has been reached. If this
is the case, the tire is so worn that it must be
replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.
ROnly mount tires of the correct size ont othe
wheels.
RBreak in new tires at moderates peeds for the
first 60 miles (100 km). The new tires only
reach their full performanc eafter 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. This also applies to the
spare wheel.
Winter operation
General notes
Have your vehicle winter-proofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing awheel"
section (
Ypage 269).
252Winter operation
Wheels and tires

Drivingwiths ummer tires
At temperature sbelo w45‡( +7 †), elasticity in
summe rtires is significantly lower and thus also
traction and braking power. Change the tires on
you rvehicle to M+S tires .Using summe rtires at
very cold temperatures coul dcause cracks to
form, therebyd amaging the tires permanently.
Mercedes-Benz cannot accep tresponsibility for
this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss.Asar esult, you couldlose control of
you rvehicle. There is arisk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã in (4 mm )are not suitabl efor use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than ãin
(4 mm) must be replaced immediately.
GWARNING
Wheela nd tire dimensions as wel lasthe type
of tire can vary between the spare wheel and
the wheel to be replaced .When the spare
wheel is mounted ,driving characteristics may
be severely affected .There is arisk of an acci-
dent.
In order to reduce risks:
Ryou should thereforea dapt yourdriving
styl eand drive carefully.
Rnever mount more than one spare wheel
that differs from the wheel to be replaced.
Ronly use aspare wheel that differs from the
wheel to be replaced for ashort time.
Rdo not deactivate ESP®.
Rhave aspare wheel that differs from the
wheel that has beenc hangedreplaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as wel lasthe wheel type.
Do not exceed amaximu mspeedof50m ph
(80 km/h) if aspare wheel of adifferent size is
installed.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both type softire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibleg rip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped 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 maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e257).
XRestart the tire pressure monitor
(Ypag e259).
Snowc hains
GWARNING
If you drive too fast with snow chains moun-
ted, they may snap. As aresult, you could
injure others and damage the vehicle. There is
ar isk of an accident.
Observe the maximu mpermissible speedf or
operation with snow chains.
!Information about the use of snow chain
compatibleA MG winter tires is applicable for
AMG tires. Use of snow chains is only per-
missible with these tires.
!On some tire sizes there is not enoug hspace
for snow chains. To avoi ddamage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" section unde r"Tires and wheels".
Wintero peration253
Wheels and tires
Z

!Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
Rwheel
Rwheel housing
Rwheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been speciallya pproved for your vehicle by
Mercedes-Benz,ora re ofacorresponding
standard of quality. For more information,
please contact aqualified 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. Observe the infor-
mation regarding permitted wheel/tire com-
binations (
Ypage 273).
RInstall the snow chains on all four wheels for
maximum tractive power and driving stability.
If you only have two snow chains, install these
as ap air on the rear wheels. The vehicle then
remains more stable under braking.
ROnly use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to aroad 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).
You may wish to deactivate ESP
®when pulling
awayw ith snow chains installed (Ypage 59).
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv- ing force (cutting action).

Tire pressure specifications
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 arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning along journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
