Load distribution
iCover strips are available as Mercedes-Benz
accessories. Contact your Mercedes-Benz Light
Truck Center.
Warning!G
Always fasten items being carried as secure-
ly as possible using cargo tie-down rings and
fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use tie
down rings, and if so equipped, always use
the cargo net* when transporting cargo.
Never drive vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.

The gross vehicle weight which is the
weight of the vehicle including fuel, tools,
spare wheel, installed accessories, pas-
sengers and luggage/cargo must never
exceed the load limit and Gross Vehicle
Weight Rating (GVWR) for your vehicle as
specified on the placard located on the
driver’s door B-pillar (
page 550). In addi-
tion, the load must be distributed in such a
way 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 indi-
cated on the certification label which can
be found on the driver’s door B-pillar
(
page 550).
For more information, see “Tire and Load-
ing Information” (
page 388).
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.Please pay attention to and comply with
the following instructions when loading the
vehicle and transporting cargo:

Always place items being carried
against front or rear seat backrests,
and fasten them as securely as possi-
ble.

The heaviest portion of the cargo
should always be kept as low as possi-
ble against front or rear seat backrests.
For additional safety when transporting
cargo while the rear seats are unoccupied,
fasten the outer seat belts crosswise into
the opposite side buckles.
Cargo tie-down rings
Your vehicle is equipped with eight cargo
tie-down rings.
Carefully secure cargo by applying even
load on all rings with rope of sufficient
strength to hold down the cargo.
iThe cargo compartment is the preferred
place to carry objects. The expanded cargo com-
partment (
page 304) should only be used for
items which do not fit in the cargo compartment
alone.
iWhile the cargo net* (page 312) will help
protect you from smaller objects, it cannot pre-
vent the movement of large, heavier objects into
the passenger compartment in an accident, dur-
ing hard braking or sudden maneuvers. Such
items must be properly secured using the cargo
tie-down rings in the cargo compartment floor.

Warning!G
Folded second-row seats are intended to
serve as a cargo compartment expansion in
conjunction with folded third-row seats only.
Do not fold the second-row seats and allow
third-row seat occupants to use folded sec-
ond-row seats as a footrest while driving.
Third-row seat occupants must, like all vehi-
cle occupants, keep both feet on the floor in
front of their seat. Otherwise, occupants
could slide under their seat belt in a colli-
sion. If occupants slide under the belt, it
would apply force at the abdomen or neck.
That could cause serious or even fatal inju-
ries. Do not fold the second-row seats and
allow third-row seat occupants to use folded
second-row seats as a table while driving.
Objects placed on folded second-row seats
may come loose during braking, vehicle ma-
neuvers, or an accident and be thrown
around the vehicle interior. Objects thrown
around the vehicle interior may cause an ac-
cident and/or serious personal injury.
!When the second-row seats are folded for-
ward, the front seats may not be moved to the re-
armost position. Otherwise you could damage

not properly locked as this can be danger-
ous. The seat could move forward and the
seat backrest could fold. You could slide un-
der the seat belt during braking, vehicle ma-
neuvers, or in an accident. If you slide under
it, the belt would apply force at the abdomen

tal injuries.

best restraint when the wearer is in a nearly
upright position and the belt is properly po-
sitioned on the body.
