Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

Loading guidelines
G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk 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, particu-
larly in the event of sudden braking or a sud-
den change in direction.
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 gross axle
weight rating of the vehicle (including occu-
pants). The values are specified on the vehi-
cle identification plate on the B-pillar of the
driver's door.
R The trunk is the preferred place to carry
objects.
R Position heavy loads as far forwards as pos-
sible and as low down in the trunk 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 tie-downs. Pad sharp edges
for protection. Stowage spaces
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, parcel
nets or stowage nets. 372

Important safety notes G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character- istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
You will find information on the maximum roof
load in the "Technical data" section
(Y page 495).
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to avoid damage to the vehicle.
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.
Ensure that, depending on the vehicle's
equipment, you can raise the panorama
roof with power tilt/sliding panel fully and
open the trunk lid fully when the roof carrier is installed.
! 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. Stowage areas
