You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windshielda nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
Washing by hand
In some countries, washing by hand is only
allowed at speciallye quipped washing bays.
Observe the legal requirements in each country.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse asoft sponge to clean.
XUse amild cleaning agent, such as acar
shampoo approved by Mercedes-Benz.
XThoroughly hose down the vehicle with agen-
tle jet of water.
XDo not point the water jet directly towards the
air inlet.
XUse plenty of water and rinse out the sponge
frequently.
XRinse the vehicle with clean water and dry
thoroughly with achamois.
XDo not let the cleaning agent dry on the paint-
work.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Powerw ashers
GWARNING
The water jet from acircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nentsd amagedint his way may fail unexpect-
edly.T here is arisk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis componentsr eplaced imme-
diately.
!Alwaysm aintainadistance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information aboutt he
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
RTires
RDoor gaps, roof gaps, joints, etc.
RSoft top (Designo retractable hardtop)
RElectrical components
RBattery
RConnectors
RLights
RSeals
RTrim
RVentilation slots
Damaged seals or electrical componentsc an
lead to leaks or failures.
!Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other com-
ponents.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similari tems
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit aqualified specialist workshop.
XRemove dirt immediately,w here possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover and
rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse off
the treated areas afterwards.
XRemove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a

XUse silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface ,use the paint care products recommen-
ded and approved by Mercedes-Benz. Thisist he
case approximately every three to five months,
depending on the climate conditions and the
care product used.

Matte finish care
!Neverpolish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
!The following may cause the paint to
become shiny and thus reduce the matte
effect:
Rstrong rubbing of the paintwork with
unsuitablem aterials
Rfrequent useofautomatic car washes
Rwashing the vehicle in direct sunlight
!Neve ruse paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax. These

MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires.
MOExtended tires may only be use dinconjunc-
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 (
Ypag e242).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommendedt hat you additionally
equip you rvehicl ewithaTIREFIT kit if you mount
tires that do not feature run-fla tproperties, e.g.
winter tires. ATIREFIT kit can be obtained from
aq ualified specialist workshop.
Winter operation
General notes
Have you rvehicl ewinter-proofed at aqualified
specialist worksho patthe onset of winter.
Observe the notes in the "Changing awheel"
section (
Ypag e274).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on you rvehicle
to M+S tires .Using summe rtires at very cold
temperatures coul dcaus ecracks to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
GWARNING
Damaged tires can caus etire inflation pres-
sure loss. As aresult, you coul dlose control of
you rvehicle. There is arisk of accident.
Check the tires regularl yfor 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 suitable for 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.
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 possibl egrip 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 e261).
XVehicles for Canada: restart the tire pres-
sure loss warning system (Ypag e262).
XRestart the tire pressure monitor
(Ypag e262).
Information about driving with an emergency
spare wheel (
Ypag e279).
Snowc hains
GWARNING
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.

TIN (Tire Identification Number)
This is aunique identifier which can be use dby
at ire manufacturer to identify tires, for example
for aproduct recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur-
er's identity code, tire size, tire type code and
the manufacturing date.

The loa dbearing index (also loa dindex) is acode
that contains the maximu mloadb earing capa-

The "Breakdown assistance" section
(Ypage241) contains information and notes on
how to dealw ithaflat tire. Informatio nondriv-
ing with MOExtended tires in the event of aflat
tire can be found under "MOExtended tires (tires
with run-fla tcharacteristics" (
Ypag e242).
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The whee lbrakes or suspension components
may als obedamaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equipped with atire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be use dnear
the valve .This coul ddamage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Always pay attention to the instructions and
safety notes when changing awheel
(
Ypag e275).
The wea rpatterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclearw earp attern
has formed on the tires. Front tires typically
wea rmore on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the interval sinthe tire manufacturer's
warranty book in you rvehicl edocuments. If no
warranty book is available,t he tires should be
rotated every 3,000 to 6,000 mile s(5,000 to
10,000 km) .Depending on tire wear, this may
be required earlier. Do not change the direction
of whee lrotation.
Clean the contact surfaces of the whee land the
brake disc thoroughly every time awhee lisr ota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system or
the tire pressure monitor.
Directio nofrotation
Tires with aspecified direction of rotation have
additiona lbenefits, e.g. if there is arisk of hydro-
planing. These advantages can only be gained if
the tires are installed corresponding to the
direction of rotation.
