Adding engine oil
GWARNING
Certain components in the engine compart-
ment ,such as the engine, radiator and parts
of the exhaust system, can become very hot.
Workingint he engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
GWARNING
If engine oil comes into contact with hot com- ponentsint he engine compartment ,itmay
ignite. There is arisk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck.L et the engine cool down and
thoroughly clean the engine oil off the com-
ponentsb efore starting the engine.
HEnvironmenta lnote
When adding oil, take care not to spill any. If
oil enter sthe soil or waterways, it is harmful to
the environment.
!Use only engine oils and oil filters that are
approved for vehicles with aservice system. A
list of the engine oils and oil filters that have
been tested and approved in accordancew ith
Mercedes-Benz Specifications for Service
Products is availableata ny authorized
Mercedes-Benz Center.
The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
RUse of engine oil additives
!Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
engine oil siphoned off.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd engine oil.
If the oil level is at or below the MIN mark on
the oil dipstick ,add 1.1 US qt (1.0 liter) of
engine oil.
XReplace cap :on the filler neck and turn
clockwise.
Ensure that the cap locks into place securely.
XCheck the oil level again with the oil dipstick
(Ypage 258).

Cleaningt he exhaust pipes
GWARNING
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 arisk 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 achrome polish.
They will otherwise lose their black sheen. For
optimal care, the faceplates should be rubbed with alightly oiled cloth after every car wash.
Commercially available engine and care oils
are suitable for this.
For heavier soiling, you can apply afine paint-
work polish with amicrofiber cloth. Remove
the excess polish residue after polishing.
Impurities combined with the effectsofr oad 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,e specially in winter and
after washing.
XClean the exhaust pipe with acare product
tested and approved by Mercedes-Benz.
Interior care
Cleaningt he display
!For cleaning, do not use any of the following:
Ralcohol-based thinner or gasoline
Rabrasive cleaning agents
Rcommercially-availableh ousehold cleaning
agents
These may damage the display surface. Do
not put pressure on the display surface when cleaning. This could lead to irreparable dam-
age to the display.
XBefore cleaning the display,m ake sure that it
is switched off and has cooled down.
XClean the display surface using acommer-
cially available microfiber cloth and TFT/LCD
display cleaner.
XDry the display surface using adry microfiber
cloth.
Cleaningt he plastic trim
GWARNING
Care products and cleaning agents containing solvents cause surfaces in the cockpit to
become porous. As aresult, plastic parts may
come loose in the event of air bag deploy-
ment. There is arisk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
!Never attach the following to plastic surfa-
ces:
Rstickers
Rfilms
Rperfume oil container or similar
You could otherwise damage the plastic.
!Do not allow cosmetics, insect repellent or
sunscreen to come into contact with the plas-
tic trim. This maintains the high-quality look of
the surfaces.
XWipe the plastic trim with adamp, lint-free
cloth, e.g. amicrofiber cloth.
XHeavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
The surface may change color temporarily.
Wait until the surface is dry again.

MOExtended tires (tires with run-flat
properties)
General notes
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. The affected tire must not show
any clearly visible damage.
You can recognize aMOExtended tire by the
MOExtended marking which appears on the
sidewal lofthe tire. You wil lfind this marking
next to the tire size designation, the load-bear-
ing capacity and the speedi ndex (
Ypage302).
MOExtended tires may be used only in conjunc-
tion with an activated tire pressure loss warning

Ifat ire pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the fillerh ose from the valve of the
faulty tire.
Note that tire sealant may escape when you
unscrew the fillerh ose.
XUSA only:Stow the tire sealant bottle and the
tire inflation compressor.
XPull away immediately.
XStop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for ashort period,t he tire is too
badlyd amaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
iUSA only: In cases such as the one men-
tioned above,c ontact an authorized
Mercedes-Benz Center. Or call
1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada).
XUSA only: Correct the tire pressure if it is still
at least 130 kPa (1.3 bar/19 psi). See the Tire
and Loading Information placard on the driv-
er's side B-pillarort he tire pressure table in
the fuel fillerf lap for values.
XTo increase the tire pressure: switch on the
tire inflation compressor.
XTo reduce the tire pressure: depresspres-
sure release button :next to pressure
gauge ;.
XWhen the tire pressure is correct, unscrew the
fillerhose from the valve of the sealed tire.
Note that tire sealant may escape when you
unscrew the fillerh ose.
XScrew the valve cap onto the tire valve of the
sealed tire.
XTo remove the tire sealant bottle from the tire
inflation compressor, press together the lock-
ing tabs on the yellow cap.
XPullthe tire sealant bottle out of the tire infla-
tion compressor.
The fillerh ose remains attached to the tire
sealant bottle.
XDrive to the nearest qualifieds pecialist work-
shop and have the tire changed there.
XHave the tire sealant bottle and the fillerh ose
replaced as soon as possible at aqualified
specialist workshop.
XHave the tire sealant bottle replaced every
