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.

ist workshops: ( Y page 24).
Loading guidelines
GWARNING
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.
GWARNING
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.
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 boot is the preferred place to carry
objects.
R position heavy loads as far forwards as pos-
sible and as low down in the boot as pos-
sible.
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 Lashing material is available at any quali-
fied specialist workshop.

Important safety notes
GWARNING
If you do not correctly store objects in the
vehicle interior, they can slip or be flung
around, thus striking vehicle occupants.
There 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.

rate Audio or COMAND Online operating
instructions).
Stowage compartment under the driver's
and front-passenger seat
GWARNING
If you exceed the maximum permitted load of
the stowage compartment, the cover is
unable to restrain the objects. Objects may
be thrown out of the stowage compartment
and hit vehicle occupants as a result. There is
a risk of injury, particularly in the event of
sudden braking or a sudden change in direc-
tion.
Always observe the maximum load of the
stowage compartment. Stow and secure
heavy objects in the boot.
The maximum permissible load of the stow-
age compartment is 1.2 kg.

( Y page 268).
R Secure the load using the lashing eyelets.
R Distribute the load on the lashing eyelets
evenly.
R Do not use elastic straps or nets to secure
a load, as these are only intended as an
anti-slip protection for light loads.
R Do not route lashing materials across sharp
edges or corners.
R Pad sharp edges for protection.

Features
Cup holders
Important safety notes
GWARNING
The cup holder cannot secure a drinks con-
tainer in place during a journey. If you use a
cup holder during a journey, the drinks con-
tainer could be flung around and liquid could
be spilt. Vehicle occupants could come into
contact with the liquid and, in particular, be
scalded by hot liquid. You could be distracted
from the traffic situation and lose control of
the vehicle. There is a risk of an accident and
injury.
Only use the cup holder when the vehicle is
stationary. Only place containers of a suitable
size in the cup holder. Seal the container, in
particular when it contains hot liquid.GWARNING
If you do not correctly store objects in the
vehicle interior, they can slip or be flung
around, thus striking vehicle occupants.
There 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 boot.
! Only use the cup holders for containers of
the right size and which have lids. The
drinks could otherwise spill.
The stowage compartments in the doors pro-
vide space for bottles:
R front: capacity up to 1.0 l
R rear: capacity up to 0.5 l

XSlowly slide oil dipstick : into the guide
tube to the stop, and take it out again.
If the level is between MIN mark = and
MAX mark ;, the oil level is correct.XIf the oil level has dropped to MIN mark
= or below, top up with 1.0 litre of engine
oil.
Adding engine oil
GWARNING
If engine oil comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil does not spill out
over the filler neck. Allow the engine to cool
down and thoroughly clean the components
that have come into contact with engine oil
before you start the engine.
HEnvironmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a
service system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
Centre.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R changing the engine oil and oil filter after
missing the change interval required by
the service system
R using engine oil additives
! Do not add too much oil. Topping up with
too much engine oil can result in damage
to the engine or to the catalytic converter.
Have excess engine oil siphoned off.
Example: engine oil filler cap
XTurn cap : anti-clockwise and remove it.XTop up the engine oil.
If the oil level is at or below the MIN mark
on the oil dipstick, top up with 1.0 litre of
engine oil.XReplace cap : on the filler neck and turn
clockwise.
Make sure that the cap locks securely into
place.XCheck the oil level again with the oil dip-
stick ( Y page 284).
For further information on engine oil, see
( Y page 340).
Checking and adding other service
products
Checking the coolant level
GWARNING
The engine cooling system is under pressure,
particularly if the engine is warm. You could
be scalded by hot coolant spraying out when
opening the cap. There is a danger of injury.
Allow the engine to cool before opening the
cap. Wear gloves and protective eyewear
when opening. Slowly turn the cap half a turn
to allow pressure to escape.
! The coolant level must only be checked
and corrected when the engine has cooled
down (coolant temperature under 40 †).
