Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment 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.

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,
particularly in the even tofsudden braking or
a sudde nchange 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
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. 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 gross axle
weight rating of the vehicle (including
occupants). The values are specified on the
vehicle 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
possible and as low down in the trunk 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 cargo tie down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
R Secure the load with sufficiently strong and
wear-resistant tie-downs. pad sharp edges
for protection. Stowage areas

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
braking or abruptly changing directions. 246

R
Always store objects so tha tthey cannot be
flung around in these or in similar
situations.
R Always make sure that objects do not
protrude from stowage compartments,
parcel 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 trunk.
Observe the loading guidelines (Y page 246).

Important safety notes G
WARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold
forwards, e.g. when braking suddenly or in the
event of an accident.
R The vehicle occupant would thereby be
pushed into the sea tbelt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
R Objects or loads in the trunk cannot be
restrained by the seat backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.
Observe the loading guidelines (Y page 246).
The left-hand and right-hand rear seat
backrests can be folded down separately to
increase the trunk capacity.
Folding the seat backrest forward i
Vehicles with memory function :when you
fold one or both parts of the rear seat
backrest forwards, the respective front
seat moves forward slightly, when
necessary, in order to avoid contact. X
Vehicles without memory function: if
necessary, move the driver's or front-
passenger seat forwards.
X Open the trunk.
X Pull right-hand or left-hand rear seat
backrest release handle 0002.
The corresponding rear seat backrest is
released. X
Fold rear seat backrest 0003forwards.
X Move the driver's or front-passenger seat
back if necessary.
Folding the seat backrest back X
Move the driver's or front-passenger seat
forward if necessary.
! Make sure that the seat belt does not
become trapped when folding the rear seat
backrest back. Otherwise, it could be
damaged. 248

i You should always engage the rear seat
backrests if you do no tneed the through-
loading feature. This will prevent
unauthorized access to the trunk from the
vehicle interior.
X Move the driver's or front-passenger seat
back if necessary. Securing cargo
Cargo tie-down rings Observe the following notes on securing
loads:
R Observe the loading guidelines
(Y page 246).
R Secure the load using the cargo tie-down
rings.
R Distribute the load on the cargo tie down
rings 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 tie-downs across sharp edges
or corners.
R Pad sharp edges for protection.
There are four cargo tie down rings in the
trunk. Vehicle with through-loading feature in the rear

WARNING
The bag hooks cannot restrain heavy objects
or items of luggage. Objects or items of
luggage could be flung around and thereby hit
vehicle occupants when braking or abruptly
changing directions. There is a risk of injury.
Only hang light objects on the bag hooks.
Never hang hard, sharp-edged or fragile
objects on the bag hooks.

Important safety notes G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving
characteristics 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-Ben zrecommends that you
only use roof carriers that have been tested and approved for Mercedes-Benzv
ehicles.
This helps to preven tdamage to the
vehicle.
Positio nthe load on the roof rack in such a
way that the vehicle will not sustain
damage even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is
installed you can:
R open the panorama roof with power tilt/
sliding panel fully
R open the trunk lid fully
! To avoid damaging or scratching the
covers, do not use metallic or hard objects
to open them.
The maximum roof load is 220 lbs(100 kg).
An incorrectly secured roof carrier or roof
load could become detached from the
vehicle. Therefore, always comply with the
installation instructions supplied by the
manufacturer of the roof carrier.
