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

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.
266Care
Maintenance and care

Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed ataqualified spe-
cialist workshop.
Observe the instructions and safety notes in the
"Changing awheel" section (
Ypage 307).
The wear pattern sonthe front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Frontt ires typically
wear more on the shoulders and the rear tires in
the center.
On vehicles that have the same size front and
rear wheels, you can rotat ethe wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000k m).D ependin gontire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Clean the contact surfaces of the wheel and the brake disc thoroughly every time awheel is rota-
ted. Check the tire pressure and, if necessary,
restart the tire pressure loss warning system
(Canada only) or the tire pressure monitor (USA
only).
Direction of rotation
Tires with aspecified direction of rotation have
additional benefits ,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.
An arrow on the sidewall of the tire indicates its
correctd irection of rotation.
Storing wheels
Storewheels that are not being used in acool,
dry and preferably dark place. Protectt he tires
from oil, grease, gasoline and diesel.

XVehicles with KEYLESS-GO start-function
or KEYLESS-GO: remove the Start/Stop but-
ton from the ignition lock (
Ypage 122).
XMake sure that the engine cannot be started
via your smartphon e(Ypage 83).
XIf included in the vehicle equipment, remove
the tire-change tool kit from the vehicle.
XSafeguard the vehicle against rolling away
(Ypage 141).
iApart from certain country-specific varia-
tions, the vehicles are not equipped with a
tire-change tool kit. Some tools for changing a
wheel are specific to the vehicle. For more
information on which tools are required to
perform awheel change on your vehicle, con-
