Cleaning the windows
G
WARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There is otherwise a risk of damaging the windows.
! Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals and pollen may under certain circumstances pre-
vent water from draining away. This can lead
to corrosion damage and damage to elec-
tronic components.
X Clean the inside and outside of the windows
with a damp cloth and a cleaning product that
is recommended and approved by Mercedes-
Benz.
Cleaning wiper blades G
WARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
! Do not pull the wiper blade. Otherwise, the
wiper blade could be damaged.
! Do not clean wiper blades too often and do
not rub them too hard. Otherwise, the graph-
ite coating could be damaged. This could
cause wiper noise.
! Hold the wiper arm securely when folding
back. The windshield could be damaged if the wiper arm smacks against it suddenly. X
Fold the windshield wiper arms away from the
windshield (Y page 118).
X Carefully clean the wiper blades with a damp
cloth.
X Fold the windshield wiper arms back again
before switching on the ignition.
Cleaning the exterior lighting !
Only use cleaning agents or cleaning cloths
which are suitable for plastic light lenses.
Unsuitable cleaning agents or cleaning cloths
could scratch or damage the plastic light len- ses.
X Clean the plastic lenses of the exterior light-
ing using a wet sponge and a mild cleaning
agent, e. g. Mercedes-Benz car shampoo or
cleaning cloths.
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 side running board !
Do not clean the aluminum insert of the side
running board with alkaline or acid-based
cleaning agents, such as wheel cleaner. Do
not use acidic wheel cleaners to remove
brake dust. The aluminum inserts could oth-
erwise be damaged.
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) between the vehicle
and the power washer nozzle. Information
about the correct distance is available from
the equipment manufacturer. 330

around the rear view camera or 360° camera with a power washer. X
Make sure that the vehicle is stationary and

360° camera: if you drive at speeds above
20 mph (30 km/h) or with the SmartKey in posi- tion 0092or0047 in the ignition lock, the cover of
the 360° camera closes. Cleaning the exhaust pipe 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.
! Vehicles with black exhaust pipes: black
chromed screens should not be polished with a chrome polish. They will otherwise lose their
black shine. For optimal care, the screens
should be rubbed with a lightly oiled cloth
after every car wash. Commercially available
engine and care oils are suitable for this.
For heavier soiling, you can apply a fine paint- work polish with a microfiber cloth. Remove
the excess polish residue after polishing.
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 chrome care
product tested and approved by Mercedes-
Benz.

the multifunction display.
You can recognize the tire pressure loss warning
by the Run Flat Indicator Active Press Run Flat Indicator Active Press
'OK' to Restart
'OK' to Restart message which appears in
the Service
Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tire pressure loss
warning system" section (Y page 358).
Important safety notes The tire pressure warning system does not warn
you of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
(Y page 354).
The tire pressure loss warning does not replace
the need to regularly check the tire pressure. An even loss of pressure on several tires at the
same time cannot be detected by the tire pres-
sure loss warning system.
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 function of the tire pressure loss warning
system is limited or delayed if:
R snow chains are mounted on your vehicle's
tires.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R you are driving with a heavy load (in the vehi-
cle or on the roof).
Restarting the tire pressure loss warn-
ing system Restart the tire pressure loss warning system if
you have:
R changed the tire pressure
R changed the wheels or tires
R mounted new wheels or tires
X Before restarting, make sure that the tire
pressures are set properly on all four tires for
the respective operating conditions.
The recommended tire pressure can be found on the Tire and Loading Information placard on the B-pillar. Additionally, a tire pressure
table is attached to the fuel filler flap. The tire
pressure loss warning system can only give
reliable warnings if you have set the correct
tire pressure. If an incorrect tire pressure is
set, these incorrect values will be monitored.
X Also observe the notes in the section on tire
pressures (Y page 354).

pressures in all four tires. The tire pressure mon-
itor warns you if the pressure drops in one or
more of the tires. The tire pressure monitor only functions if the corresponding sensors are
installed in all wheels. 358
