vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
The cargo compartment is the preferred place
to carry objects. Always use cargo tie-down
rings, and if so equipped, always use the cargo
net when transporting cargo.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
Load distribution The Gross Vehicle Weight (GVW) is the weight
of the vehicle including:
R
fuel
R tools
R spare wheel
R installed accessories R
passengers
R luggage/cargo
It must never exceed the load limit and the
Gross Vehicle Weight Rating (GVWR) for your
vehicle. The load limit and the GVWR are
specified on the placard located on the
driver’s door B-pillar ( Y page 236).
In addition, the load must be distributed so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the certification
label located on the driver’s door B-pillar
(Y page 236).
For more information, see “Tire and Loading
Information” ( Y page 237).
The handling characteristics of a fully loaded
vehicle depend greatly on the load
distribution. It is therefore recommended to
load the vehicle according to the illustration
shown. The heaviest items are to be placed
towards the front of the vehicle.
i The cargo compartment is the preferred
place to carry objects. The expanded cargo
volume ( Y page 189) should only be used
for items which do not fit in the cargo
compartment alone.
Please pay attention to and comply with the
following instructions when loading the
vehicle and transporting cargo:
R Always place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
R The heaviest portion of the cargo should
always be kept as low as possible against
front or rear seat backrests. Roof rack

Warning!
Only use the roof rack when the basic carrier
bars have been completely mounted. The left
and right roof rails are only stabilized by
means of the basic carrier bars being
mounted.
Follow the manufacturer’s installation
instructions. Otherwise, an improperly
attached roof rack system or its load could
become detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicle without the roof rack loaded.
Make sure
R you can raise the tilt/sliding sunroof (or
tilt/sliding panel) at the rear completely
R you can open the tilt/sliding sunroof (or
tilt/sliding panel) completely
R you can open the tailgate completely X
Flip trim covers : open.
X Only attach the roof rack to the anchorage
points under trim covers :.
X Observe manufacturer’s instructions for
installation. Parcel nets
G
Warning!
Vehicles with Occupant Classification System
(OCS)
Do not place objects with a combined weight
of more than 4.4 lbs (2 kg) into the parcel net
on the back of the front passenger seat.
Otherwise, the OCS may not be able to
properly approximate the occupant weight
category. G
Warning!
Parcel nets are intended for storing light-
weight items only, such as road maps, mail,
etc.
Heavy objects, objects with sharp edges, or
fragile objects may not be transported in the
parcel nets. In an accident, during hard
braking, or sudden maneuvers, they could be
thrown around inside the vehicle and cause
injury to vehicle occupants.
Parcel nets cannot protect transported goods
in the event of an accident.
Parcel nets are located in the front passenger
footwell and on each of the front seat
backrests. Cargo tie-down rings
Your vehicle is equipped with eight cargo tie-
down rings.
Always follow loading instructions
(Y page 186).
Carefully secure cargo by applying even load
on all the cargo tie-down rings with a rope of
sufficient strength to hold down the cargo. 188

Notes
! Only

use tires which have been tested and
approved by Mercedes-Benz. Tires
approved by Mercedes-Benz are developed
to provide best possible performance in
conjunction with the driving safety systems
on your vehicle such as the ABS or the
ESP ®
. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding
the following on the tire’s sidewall:
R MO = Mercedes-Benz Original
equipment tires
R MOE

= Mercedes-Benz Original Extended
(tires with limited run-flat
characteristics) original equipment tires
Using tires other than those approved by
Mercedes-Benz may result in damage that
is not covered by the Mercedes-Benz
Limited Warranty.
For information on driving with MOExtended
tires, see the “Practical hints” section
(Y page 330).
