Cleaning the exhaust pipes
G WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents, such as bathroom
cleaner or wheel cleaner.
! Mercedes-AMG vehicles with black
exhaust pipes: the black-chrome tailpipe
finishers should not be polished with a
chrome polish. They will otherwise lose
their black sheen. For optimal care, the
faceplates should be rubbed with a lightly oiled cloth after every car wash. Commer-
cially available engine and care oils are
suitable for this.
For heavier soiling, you can apply a fine
paintwork polish with a microfiber cloth.
Remove the excess polish residue after pol-
ishing.
Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. You
can restore the original shine of the exhaust
pipe by cleaning it regularly, especially in win-
ter and after washing. X
Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
Interior care
Cleaning the display
! For cleaning, do not use any of the fol-
lowing: R
alcohol-based thinner or gasoline R
abrasive cleaning agents R
commercially-available household clean-
ing agents
These may damage the display surface. Do
not put pressure on the display surface
when cleaning. This could lead to irrepara-
ble damage to the display. X
Before cleaning the display, make sure that
it is switched off and has cooled down. X
Clean the display surface using a commer-
cially available microfiber cloth and
TFT/LCD display cleaner. X
Dry the display surface using a dry micro-
fiber cloth.

Cleaning the seat covers General notes
! Do not use a microfiber cloth to clean
covers made out of real leather, artificial
leather or DINAMICA. If used often, these
can damage the cover.
Note that regular care is essential to ensure
that the appearance and comfort of the cov-
ers is retained over time.
Genuine leather seat covers
! To retain the natural appearance of the
leather, observe the following cleaning
instructions: R
Clean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth. R
Make sure that the leather does not
become soaked. It may otherwise
become rough and cracked. R
Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a quali-
fied specialist workshop.

It exhibits natural surface characteristics, for
example: R
differences in the texture R
marks caused by growth and injury R
slight nuances of color
These are characteristics of leather and not
material defects. Care 307
Maintenance and care Z

Seat covers of other materials
! Observe the following when cleaning: R
clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). R
clean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning
results depend on the type of dirt and
how long it has been there. R
clean DINAMICA covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
Cleaning the seat belts
G WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of
an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above 176 ‡
(80 †) or in direct sunlight. X

Care
Maintenance and care

weeks when cold and inflated to the pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver's door B-pillar or the tire pres-
sure label on the inside of the fuel filler flap. If
your vehicle has tires of a different size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label, you should determine the
proper tire pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale lights up,
you should stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on a significantly underin-
flated tire causes the tire to overheat and can
lead to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure, even if
underinflation has not reached the level to
trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunct ion indicator is combined with
the low tire pressure telltale. When the sys-
tem detects a malfunction, the warning lamp
will flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of incom-
patible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to
ensure that the replacement or alternate Tires
and wheels allow the TPMS to continue to
function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
( Y
page 332). Note that the correct tire pres-
sure for the current operating situation must
first be taught-in to the tire pressure monitor.
If there is a substantial loss of pressure, the
warning threshold for the warning message is
aligned to the reference values taught-in.
Restart the tire pressure monitor after adjust-
ing the pressure of the cold tires
( Y
page 338). The current pressures are
saved as new reference values. As a result, a
warning message will appear if the tire pres-
sure drops significantly.
The tire pressure monitor does not warn you
of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
( Y
page 332).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering movements.
The tire pressure monitor has a yellow warn-
ing lamp in the instrument c luster for indicat-
in
g pressure loss or a malfunction. Whether
the warning lamp flashes or lights up indi-
cates whether a tire pressure is too low or the
tire pressure monitor is malfunctioning: R
if the warning lamp is lit continuously, the
tire pressure on one or more tires is signif-
icantly too low. The tire pressure monitor is
not malfunctioning. R
if the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning. Tire pressure 337

If you or others come into contact with fuel,
observe the following: R
Wash away fuel from skin immediately
using soap and water. R
If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay. R
If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing. R
Immediately change out of clothing which
has come into contact with fuel.
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 there-
fore higher than with premium-grade gaso-
line.
Maintenance
Inform your authorized Mercedes-Benz Cen-
ter 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 notice-
ably longer when operating with E85 fuel.
E85 fuel is not suitable for use at outside
temperatures under -4 ‡ (-20 †). Engine oil
General notes
! Never use engine oil or an oil filter of a
specification other than is necessary to ful-
fill the prescribed service intervals. Do not
change the engine oil or oil filter in order to
achieve longer replacement intervals than
those prescribed. You could otherwise
cause engine damage or damage to the
exhaust gas aftertreatment.
Follow the instructions in the service inter-
val display regarding the oil change. Other-
wise, you may damage the engine and the
exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
( Y
page 365).
The engine oils are matched to the perform-
ance of Mercedes-Benz engines and service
intervals. You should therefore only use
engine oils and oil filters that are approved for
vehicles with maintenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Cen-
ter. Or visit the website

Coolant
Important safety notes
G WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g.
on the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.Service products and filling capacities 369

! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
page 365).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks: R
corrosion protection R
antifreeze protection R
raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡( -37 †), the boiling point of the cool-
ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †) .R
no t exceed 55 % (antifreeze protection
do wn to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
Mercedes-Benz recommends coolant or anti-
freeze/corrosion inhibitor concentrate in
accordance with MB Specifications for Ser-
vice Products 310.1.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
i The coolant is checked with every main-
tenance interval at a qualified specialist
workshop. Filling capacities Model Capacity
