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, 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.
GWARNING
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.
GWARNING
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:
RNever exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle
identification plate on the B-pillar of the
driver's door.
RThe cargo compartment is the preferred
place to carry objects.
RPosition heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible.
RThe load must not protrude above the
upper edge of the seat backrests.
RAlways place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
RAlways place the load behind unoccupied
seats if possible.
RUse the cargo tie-down rings and the parcel
nets to transport loads and luggage.
RUse cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
RThe maximum load capacity of the stowage
well under the cargo compartment floor is
55 lbs (25 kg).
RSecure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges
for protection.
!Do not position the load on one part of the
folding cargo compartment floor only. The
maximum load capacity of the folding cargo
compartment floor is 220 lbs (100 kg). Dis- tribute the weight evenly to avoid damaging
the cargo compartment floor. Place a solid
board under the load if necessary. Please

Cargo net
Important safety notes
GWARNING
On its own, the cargo net cannot secure or
restrain heavy objects, items of luggage and
heavy loads. You could be hit by an unsecured
load during sudden changes in direction,
braking or in the event of an accident. There is
an increased risk of injury or even fatal injury.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping over, e.g. by
using tie downs, even if you are using the
cargo net.
It is important to use a cargo net if you load
the vehicle with small objects above the seat
backrests. For safety reasons, always use a
cargo net when transporting loads.
Damaged cargo nets can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop.
Attaching and tightening the cargo net
You have two options for hooking in the cargo
net:
Rwith cargo compartment enlargement: the
brackets are behind the B‑pillar and the
cargo tie-down rings to tension the net are
on the sides of the rear-compartment foot-
well.
Rwithout cargo compartment enlargement:
the brackets are behind the C-pillar and the cargo tie-down rings to tension the net are
in the cargo compartment (
Ypage 285).

Roof carrier
Important safety notes
GWARNING
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.
!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 rack 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 tailgate fully when the roof carrier is installed. You will find information on the maximum roof
load in the "Technical data" section
(
Ypage 383).
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.
Attaching the roof carrier
XSecure the roof carrier to the roof rails. In
doing so, observe the manufacturer's
installation instructions.
Features
Cup holder
Important safety notes
GWARNING
The cup holder cannot hold a container secure
whilst traveling. If you use a cup holder whilst
traveling, the container may be flung around
and liquid may be spilled. The vehicle occu-
pants may come into contact with the liquid
and if it is hot, they may be scalded. You may
be distracted from the traffic conditions and
you could 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 use the cup holder for con-
tainers of the right size. Always close the con-
tainer, particularly if the liquid is hot.
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction.
