When indicator lamp:flashes green: pro-
gramming was successful. The next step is to
synchronize the rolling code.
XRelease button Bof remotec ontrolAof the
garage door drive.
If indicator lamp :lights up red: repeat the
programmingp rocess for the corresponding
button on the rear-view mirror. When doing
so, vary the distanc ebetween remotec ontrol
A and the rear-view mirror.
The required distanc ebetween remotec on-
trol Aand the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. You
should test every position for at least
25 seconds before trying another position.
Problems when programming
If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take not eofthe following instruc-
tions:
RCheck the transmitter frequenc yused by
garage door drive remotec ontrolAand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remotec ontrolAfor the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequenc yrange of 280 to
433 MHz.
RReplace the batteries in garage door remote
control A.This increases the likelihood that
garage door remotec ontrolAwill transmit a
stron gand precise signal to the integrated
garage door opener.
RWhen programming, hold remotec ontrolA
at varying distances and angles from but-
tons ;to? which you are programming. Try
various angles at adistanc ebetween 2and
8i nches (5to 20 cm) or at the same angle but
at varying distances.
RIf another remotec ontrolAis available for
the same garage door drive, repeat the same
programmings teps with this remotec ontrol
A.B eforep erforming these steps, make sure
that new batteries have been installed in
garage door drive remotec ontrolA.
RNote that some remotec ontrols only transmit
for alimited amount of time (the indicator
lamp on t
he remotec
ontrol goes out). Press button
Bon remotec ontrolAagain before
transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performst he function of the

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
