Problems with the sliding sunroof
Your vehicle may be equipped with a sliding sunroof or a panorama roof with power tilt/sliding
panel. In this section, the term "sliding sunroof" refers to both types of sliding sunroof.
GWARNING
If you close the sliding sunroof again immediately after it has been blocked or reset, the sliding
sunroof closes with increased or maximum force. The reversing feature is then not active. Parts
of the body could be trapped in the closing area in the process. This poses an increased risk of
injury or even fatal injury.
Make sure that no parts of the body are in the closing area.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the switch briefly in any direction
The closing process is stopped.

RAlways keep the engine running and in gear
when driving on a downhill gradient.
Activate DSR (Ypage 256).
RAlways keep the doors, tailgate, windows
and sliding sunroof closed while driving.
RAdapt your speed to the terrain. The
rougher, steeper or more ruts on the
terrain, the slower your speed should be.
RDrive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
RDrive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
RLook out for obstacles, such as rocks,
holes, tree stumps and furrows.
RCheck the depth of water before fording
rivers and streams.
RWhen fording, do not stop and do not
switch off the engine.
ROn sand, drive quickly to overcome the
rolling resistance. Otherwise the vehicle's
wheels could become stuck in loose
ground.
RDo not jump with the vehicle as this will
interrupt the vehicle's propulsion.
RAlways keep the engine running and in gear
when driving on a slope.
RDo not shift the automatic transmission to
transmission positionN.

198Driving tips
Driving an d parking

Ruse in mountainous terrain or on poor road
surfaces
Rif the engine is often left idling for long
periods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center.

An extensive Mercedes-Benz Service network
is also available in other countries. You can

Care
General notes
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
!For cleaning your vehicle, do not use any
of the following:
Rdry, rough or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents
recommended and approved by Mercedes-
Benz.
