Maintenance and care

Cleaning the mirror turn signals
! Only use cleaning agents or cleaning cloths
that are suitable for plastic lenses. Unsuitable
cleaning agents or cleaning cloths could
scratch or damage the plastic lenses of the
mirror turn signals. X
Clean the plastic lenses of the mirror turn sig-
nals in the exterior mirror housing using a wet
sponge and mild cleaning agent, e.g.
Mercedes-Benz car shampoo or cleaning
cloths.
Cleaning the sensors
! If you clean the sensors with a power
washer, make sure that you keep a distance
of at least 11.8 in (30 cm ) betwee n the vehicl e
and the power washer nozzle. Information
about the correct distance is available from
the equipment manufacturer.
X
Clean sensors C of the driving systems with
water, car shampoo and a soft cloth.

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.
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 winter and
after washing. X
Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
Interior care

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 microfiber
cloth.
Cleaning the plastic trim
G WARNING
Care products and cleaning agents containing
solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts may
come loose in the event of air bag deploy-
ment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
! Do not affix the following to plastic surfaces: R
stickers R
films R
scented oil bottles or similar items
You can 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. X
Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfiber cloth. X
Heavy 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.

ments
! Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, polishes
or waxes. There is otherwise a risk of damag-
ing the surface.
! Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and can
lose their shine if chrome polish is used. Use
a damp, lint-free cloth instead when cleaning
the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you are
unsure as to whether the trim pieces are
chrome-plated or not, consult an authorized
Mercedes-Benz Center. X

Flat tire
Preparing the vehicle Your vehicle may be equipped with: R
MOExtended tires (tires with run-flat proper-
ties) ( Y
page 278)
Vehicle preparation is not necessary on vehi-
cles with MOExtended tires R
a TIREFIT kit ( Y
page 277)R
an emergency spare wheel ( Y
page 317)
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.
Information on changing and mounting wheels
( Y
page 312). X
Stop the vehicle on solid, non-slippery and
level ground, as far away as possible from
traffic. X
Switch on the hazard warning lamps. X
Secure the vehicle against rolling away
( Y
page 141).X
If possible, bring the front wheels into the
straight-ahead position. X
Vehicles with AIRMATIC: make sure that "nor-
mal" level is selected ( Y
page 159).X
Switch off the engine. X
Remove the SmartKey from the ignition lock.
or, on vehicles with KEYLESS ‑ GO:X
Open the driver's door.
T he vehicle electronics now have status 0 .
This is the same as the SmartKey having been
removed. X
Remove the Start/Stop button from the igni-
tion lock ( Y
page 123).X
Make sure that the passengers are not endan-
gered as they do so. Make sure that no one is
near the danger area while a wheel is being changed. Anyone who is not directly assisting
in the wheel change should, for example,
stand behind the barrier. X
Get out of the vehicle. Pay attention to traffic
conditions when doing so. X
Close the driver's door.
MOExtended tires (tires with run-flat
properties)
General notes 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. 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 307).
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 221). 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 p ossible 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 permissible
speed of 50 mph (80 km/h).278
