Useful information
i This Owner's Manual describes all mod-
els,
series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24). Loading guidelines
G
WARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over

or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially
when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G
WARNING
Combustion engines emit poisonous exhaust
gases
such as carbon monoxide. If the tailgate
is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load:
R when transporting a load, never exceed the
maximum permissible gross vehicle weight or the permissible axle loads for the vehicle
(including occupants).
R the luggage compartment is the preferred
place to carry objects.
R position

heavy loads as far forwards as pos-
sible and as low down in the luggage com-
partment as possible.
R the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
R always place the load behind unoccupied
seats if possible.
R use the lashing eyelets and the luggage
nets to transport loads and luggage.
R only use lashing eyelets and fastening com-
ponents that are suitable for the weight and
size of the load.
R the maximum load capacity of the stowage
well under the luggage compartment floor
is 25 kg.
R secure the load with sufficiently strong and
wear-resistant lashing material. Pad sharp
edges for protection.
i Lashing material is available at any quali-
fied specialist workshop.
! Do not position the load on one part of the
folding luggage compartment floor only.
The maximum load capacity of the folding
luggage compartment floor is 100 kg.
Spread the weight evenly to avoid damag-
ing the luggage compartment floor. Place a
solid board under the load if necessary.
Please note that the load on the luggage
compartment floor will be increased when
the load is lashed down. 268

is a risk of injury, especially when brak-
ing or abruptly changing directions.
R Always store objects so that they cannot be
flung around in these or in similar situa-
tions.
R Always make sure that objects do not pro-
trude from stowage compartments, lug-
gage nets or stowage nets.
R Close lockable stowage compartments
while driving.
R Stow and secure objects that are heavy,
hard, pointy, sharp-edged, fragile or too
large in the luggage compartment.

WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for-
wards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt cannot protect as intended and
could result in additional injury.
R Objects or loads in the boot/luggage com-
partment cannot be restrained by the seat
backrest.
This poses an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged before every trip.

Information about Service Resetting the ASSYST PLUS service inter-
val display
!
If the ASSYST PLUS service interval dis-
play has been inadvertently reset, this set-
ting

can be corrected at a qualified special-
ist workshop.
Have service work carried out as described
in the Service Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
A qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, will reset the
ASSYST PLUS service interval display after
the service work has been carried out. You
can also obtain further information on main-
tenance work, for example.
Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
R regular city driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R for frequent operation in mountainous ter-
rain or on poor road surfaces
R if the engine is often left idling for long peri-
ods
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for exam-
ple, changed more frequently. The tyres must be checked more frequently if the vehicle is
operated under increased loads. Further
information can be obtained at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre.
Driving abroad
An

extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Mercedes-Benz Service24h" section
of the Service Booklet. Care
General notes
H
Environmental note
Dispose of empty packaging and cleaning
cloths
in an environmentally responsible man-
ner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning 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 up 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 clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. 290
Care
Maintenance and care

Cleaning the mirror turn signal
!
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
signals

in the exterior mirror housing using
a wet sponge and a mild cleaning agent,
e.g. Mercedes-Benz car shampoo or clean-
ing cloths.
Cleaning the sensors !
If
you clean the sensors with a high-pres-
sure cleaner, make sure that you keep a
distance of at least 30 cm between the
vehicle and the high-pressure cleaner noz-
zle. Information about the correct distance
is available from the equipment manufac-
turer. X
Clean sensors : of the driving systems
with water, car shampoo and a soft cloth.
Cleaning the reversing camera !
Do
not clean the camera lens and the area
around the reversing camera with a high-
pressure cleaner. X
Use clear water and a soft cloth to clean
camera lens :.
Cleaning the exhaust tail pipes 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 win-
ter and after washing.
! Do not clean the exhaust pipe with acid-
based cleaning agents such as sanitary
cleansers or wheel cleaners.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
! AMG vehicles with black exhaust pipes:
do not use chrome polish to polish black
chromed screens. They will otherwise lose
their

silky black shine. Rub the screen using
a lightly oiled cloth after every car wash.
Commercially available engine oils, WD 40
or Ballistol are suitable oils.
