Important safety notes
G WARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the navigation system.
General notes
Among other things, correct functioning of the
navigation system depends on GPS reception. In
certain situations, GPS reception may be
impaired, there may be interference or there
may be no reception at all, e.g. in tunnels or
parking garages. Audio 20 is equipped with MARGIN ®

cle are covered with a decorative foil. Main-
tain a distance of at least 70 cm between the
foil-wrapped parts of the vehicle and the noz-
zle of the high pressure cleaner.
Information about the correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Cleaning the paintwork
! Do not affix: R
stickers R
films R
magnetic plates or similar items
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 a qualified specialist workshop. X
Remove dirt immediately, where possible,
while avoiding rubbing too hard. X
Soak insect remains with insect remover and
rinse off the treated areas afterwards. X
Soak bird droppings with water and rinse off
the treated areas afterwards. X
Remove coolant, brake fluid, tree resin, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid. X
Use tar remover to remove tar stains. X
Use 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. This is the
case approximately every three to five months,
depending on the climate conditions and the
care product used.
If dirt has penetrated the paint surface or if the
paint has become dull, the paint cleaner recom-
mended and approved by Mercedes-Benz
should be used.
Do not use these care products in the sun or on
the hood while the hood is hot. X
Use a suitable touch-up stick, e.g. MB Touch-
Up Stick, to repair slight damage to the paint-
work quickly and provisionally.
Matte finish care
! Never polish 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: R
strong rubbing of the paintwork with
unsuitable materials R
frequent use of automatic car washes R
washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax. These
products are only suitable for high-gloss sur-
faces. Their use on vehicles with matte finish
leads to considerable surface damage (shiny,
mottled areas).
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
a clear matte finish.
The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products. Care 337

or more tires. The affected tire must not show
any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index ( Y
page 374).
MOExtended tires may only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If a pressure loss warning message appears
in the multifunction display: R
observe the instructions in the display mes-
sages ( Y
page 280).R
check the tire for damage. R
if driving on, observe the following notes.
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partially laden. When the vehicle is fully
laden it is approximately 19 miles (30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon: R
vehicle speed R
road condition R
outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed a maximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for your vehicle's
tires: R
size R
the type and R
the "MOExtended" mark
If a tire has gone flat and cannot be replaced
with a MOExtended tire, a standard tire may be
used as a temporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
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.
Important safety notes
G WARNING

Operation
Wheels and tires

Exception: it is permissible to install a differ-
ent type or make in the event of a flat tire.
Observe the "MOExtended tires (tires with
run-flat characteristics" section ( Y
page 343).R
Only mount tires of the correct size onto the
wheels. 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 343).
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 winter-proofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section ( Y
page 379).
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 tire s. Usin g su mmer 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.

Technical data

Flexible Fuel vehicles can be refueled with the
following fuel types: R
premium-grade unleaded gasoline R
E85 fuel R
a mixture of E85 fuel and premium-grade
unleaded gasoline
i Flexible Fuel vehicles can be recognized by
the Ethanol up to E85 sticker on the inside of
the fuel filler flap.
Fuel consumption The energy content of E85 fuel is less than that
of the same amount of premium-grade gasoline.
The amount of fuel consumed when operating
the vehicle with E85 fuel is therefore higher than
with premium-grade gasoline.
Maintenance Inform your authorized Mercedes-Benz Center
that you are operating or have operated the
vehicle with E85 fuel.
Low outside temperatures If the outside temperature is below 32 ‡( 0 †),
the starting procedure can take noticeably lon-
ger when operating with E85 fuel.
E85 fuel is not suitable for use at outside tem-
peratures under -4 ‡ (-20 †).

! Never use engine oil or an oil filter of a spec-
ification other than is necessary to fulfill the
prescribed service intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval
display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products ( Y
