Maintenance and care

Cleaning the steering wheel and gear or
selector lever
XThoroughly wipe with a damp cloth or useleather care agents that have been recom-mended and approved by Mercedes-Benz.
Cleaning genuine wood and trim ele-
ments
!Do not use solvent-based cleaning agentssuch as tar remover, wheel cleaners, polishesor 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 aremostly made of anodized aluminum and canlose their shine if chrome polish is used. Usea damp, lint-free cloth instead when cleaningthe trim pieces.
If the chrome-plated trim pieces are verydirty, you can use a chrome polish. If you areunsure as to whether the trim pieces arechrome-plated or not, consult an authorizedMercedes-Benz Center.
XWipe the wooden trim and trim pieces with adamp, lint-free cloth, e.g. a microfiber cloth.
XHeavy soiling:use care and cleaning prod-ucts recommended and approved byMercedes-Benz.
Cleaning the seat covers
General notes
!Do not use a microfiber cloth to clean coversmade out of real leather, artificial leather orDINAMICA. If used often, these can damagethe cover.
Note that regular care is essential to ensure thatthe appearance and comfort of the covers isretained over time.
Genuine leather seat covers
!To retain the natural appearance of theleather, observe the following cleaninginstructions:
RClean genuine leather covers carefully witha damp cloth and then wipe the coversdown with a dry cloth.
RMake sure that the leather does notbecome soaked. It may otherwise becomerough and cracked.
ROnly use leather care agents that havebeen tested and approved by Mercedes-Benz. You can obtain these from a qualifiedspecialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, forexample:
Rdifferences in the texture
Rmarks caused by growth and injury
Rslight nuances of color
These are characteristics of leather and notmaterial defects.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a clothmoistened with a solution containing 1%detergent (e.g. dish washing liquid).
Rclean cloth covers with a microfiber clothmoistened with a solution containing 1%detergent (e.g. dish washing liquid). Rubcarefully and always wipe entire seat sec-tions to avoid leaving visible lines. Leavethe seat to dry afterwards. Cleaning resultsdepend on the type of dirt and how long ithas been there.
Rclean DINAMICA covers with a damp cloth.Make sure that you wipe entire seat sec-tions to avoid leaving visible lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of
an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.

XClose 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 oneor more tires. The affected tire must not showany clearly visible damage.
You can recognize a MOExtended tire by theMOExtended marking which appears on thesidewall of the tire. You will find this markingnext to the tire size designation, the load-bear-ing capacity and the speed index (Ypage 305).
MOExtended tires may be used only in conjunc-tion with an activated tire pressure loss warningsystem (Canada only) or tire pressure monitor(USA only).
If a pressure loss warning message appearsin the multifunction display:
Robserve the instructions in the display mes-sages (Ypage 213).
Rcheck the tire for damage
Rif driving on, observe the following notes
The driving distance possible in run-flat mode isapproximately 50 miles (80 km) when the vehi-cle is partially laden. When the vehicle is fullyladen it is approximately 19 miles (30 km).
In addition to the vehicle load, the driving dis-tance possible depends upon:
Rvehicle speed
Rroad condition
Routside temperature
The driving distance possible in run-flat modemay be reduced by extreme driving conditionsor maneuvers, or it can be increased through amoderate style of driving.
The driving distance possible in run-flat mode iscounted from the moment the tire pressure losswarning appears in the multifunction display.
You must not exceed a maximum speed of50 mph (80 km/h).
When replacing one or all tires, please observethe following specifications for your vehicle'stires:
Rsize
Rtype and
Rthe "MOExtended" marking
If a tire has gone flat and cannot be replacedwith a MOExtended tire, a standard tire may beused as a temporary measure. Make sure thatyou use the proper size and type (summer orwinter tire).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehicle with a TIREFIT kit if you mounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit may be obtained froma qualified specialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.
