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 27). Stowage areas
Loading guidelines
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
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
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 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 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 behind unoccupied
seats if possible.
R secure the load with sufficiently strong and
wear-resistant lashing material. Pad sharp
edges for protection.
i Load restraints are available at any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. Stowage compartments
Important safety notes G
WARNING
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. 368

Ski/snowboard bag
Important safety notes G
WARNING
The skibag in conjunction with the lashing
straps cannot restrain any objects other than skis.
Vehicle occupants could be struck in the
event of sudden braking or an accident, for
instance, if you:
R transport other heavy or sharp-edged
objects in the skibag
R do not secure the skibag with the lashing
straps
There is a risk of accident and injury.
Store only skis in the skibag. Always secure
the skibag with the lashing straps so that it
cannot move around.
A maximum of four pairs of skis or two snow- boards can be transported in the ski/snow-
board bag.
Securing the ski/snowboard bag in the
boot X
Fold the middle rear seat backrest forwards
(Y page 372).
X Slide the ski/snowboard bag between the
two outside rear seat backrests. Ensure
that the wheels of the ski/snowboard bag
are in the boot.
X Open the ski/snowboard bag with zip :
and place the skis or snowboards inside it. X
Close the ski/snowboard bag.
X Pull tensioning strap ;tight by the loose
end until the skis or snowboards are held
firmly inside the ski/snowboard bag. X
Engage tensioning strap =in a diagonal
pattern on hooks ?in lashing eyelets A
as shown. Through-loading facility in the rear
bench seat
Important safety notes G
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 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.
Observe the loading guidelines (Y page 368).
The outside and the middle rear seat backr-
ests can be folded down separately to
increase the boot capacity. The division ratio is 40% to 20% to 40%. Stowage areas

Bag hook G
WARNING
The bag hooks cannot restrain heavy objects
or items of luggage. Objects or items of lug-
gage could be flung around and thereby hit
vehicle occupants when braking or abruptly
changing directions. There is a risk of injury.

Never hang hard, sharp-edged or fragile
objects on the bag hooks.
! The bag hook can bear a maximum load of
3 kg. Do not use it to secure a load. :
Bag hook EASY-PACK boot box
Important safety notes G
WARNING
When the load surface moves up, your hands may become trapped on the frame of the
EASY-PACK boot box. There is a risk of injury.
When the load surface moves up, make sure
that your hands are not within the sweep of
the load surface. If someone becomes trap-
ped, carefully push the centre of the load sur- face downward.
! When the EASY-PACK convenience box is
pulled out, no objects may be placed on the frame of the box or pushed onto the frame
from above. Otherwise, the box could be
damaged.
! Sharp-edged, pointed or fragile objects
can damage the EASY-PACK boot box and
then be thrown out. There is a risk of injury.
Do not transport sharp-edged, pointed or
fragile objects in the EASY-PACK boot box. Always store and secure these or similar
objects in the boot outside of the EASY-
PACK boot box.
! If you exceed the maximum permitted
load of the EASY-PACK boot box, objects
can be thrown out of the EASY-PACK boot
box and strike vehicle occupants. There is a risk of injury, particularly in the event of
sudden braking or a sudden change in
direction.
Always observe the maximum permitted
load of the EASY-PACK boot box. Always
store and secure heavy objects in the boot
outside of the EASY-PACK boot box.
The maximum permitted load of the EASY-
PACK boot box is 10 kg. With a load of above approximately 5 kg, the bottom of the box
moves downward until it rests on the mat of
the boot floor. Thus, overloading of the box is
avoided.

Roof carrier
Important safety notes G
WARNING
When a load is transported on the roof, the
vehicle's centre of gravity rises and the han-
dling changes. If you exceed the maximum
roof load, the handling as well as steering and braking characteristics are severely affected.
There is a risk of an accident.
Always observe the maximum roof load and
adapt your driving style.
The maximum roof load can be found in the
"Technical data" (Y page 476).
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the vehi-
cle.
Position the load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is fitted
you can:
R raise the sliding sunroof/panorama slid-
ing sunroof fully
R open the boot lid fully
! To avoid damaging or scratching the cov-
ers, do not use metallic or hard objects to
open them.
An incorrectly secured roof carrier or roof
load may become detached from the vehicle.
You must therefore ensure that you observe
the roof carrier manufacturer's installation
instructions.
Vehicles with panorama sliding sunroof: if
a roof carrier is fitted, the panorama sliding
sunroof cannot be opened. In order to allow
ventilation of the vehicle interior, you can
raise the panorama sliding sunroof.
If a roof carrier approved by Mercedes-Benz
makes contact with the panorama sliding sunroof, the sunroof will lower slightly but
remain raised in the rear.
Attaching the roof carrier X
Open covers :carefully in the direction of
the arrow.
X Fold covers :upwards.
X Only secure the roof carrier to the anchor-
age points under covers :.
X Observe the manufacturer's installation
instructions. Features

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. 376
