Stowage areas
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. Exhaust
gases can enter the vehicle interior if the boot
lid is open when the engine is running, espe-
cially if the vehicle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the boot lid. Never drive with the boot lid
open. 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.
The handling characteristics of a laden vehicle
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 never exceed the maximum permissible gross
vehicle weight or the permissible axle loads
for the vehicle (including occupants).
R the boot is the preferred place to store
objects.
R position heavy loads as far forwards as pos-
sible and as low down in the boot 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 secure the load with sufficiently strong and
wear-resistant lashing material. Pad sharp
edges for protection.
i Load restraints are available at any qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. Stowage compartments
Important safety notes G
WARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants. In
addition, cupholders, open stowage spaces
and mobile phone brackets cannot always
retain all objects they contain. There is a risk of injury, particularly in the event of sudden
braking or a sudden change in direction.
R Always stow objects so that they cannot be
thrown around in such situations.
R Always make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
R Close the lockable stowage spaces before
starting a journey.
R Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the boot.
Observe the loading guidelines (Y page 265). Stowage areas

Information about Service Resetting the ASSYST PLUS service inter-
val display
! If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at a qualified specialist work-
shop.
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 maintenance
work, for example.
Special service requirements The prescribed service interval is based on nor-
mal 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 intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper- 288

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 cleaning. Braking heats the brake discs and the brake
pads/linings, thus drying them. The vehicle
can then be parked up.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents recom-
mended and approved by Mercedes-Benz. Washing the vehicle and cleaning the
