In the event of an accident, haveadamaged
cargo compartment floor or loading area ,the
cargo tie-down rings and the tie down checked
at as pecialist workshop. Otherwise ,the load
may not be correctly secured the next time any-
thing is stowed.
Even if you follow all loading guidelines, the load
increases the risk of injury in the event of an
accident. Observe the information in the "Secur- ing aload "(
Ypage 234) and "Loa ddistribution"
(Ypage 233) sections.
You wil lfind information abou tthe maximum
roof load and maximum tailgate load in the
"Cargo tie-down points and carrier systems"
section (
Ypage 304). You wil lfind information
abou troof carriers under "Carrier systems"
(
Ypage 238).
Before loading
!
The anti-slip mats cannot be used for secur-
ing goods and must be replaced when they
show signs of:
RPermanent deformatio nand crushing
RCrack formation
RCuts
XTire pressure: check the tire pressure and
correct if necessary (Ypage 270).
XCargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to pre-
vent the load from slipping.
XPlace non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary.
During loading
XObserve the gross axle weight rating and per-
missible gross vehicle weight for you rvehicle.
Take into account that you rvehicle's curb
weight is increased if accessorie soroptional equipment are installed. The maximum pay-
load is thus reduced.
XObserve the notes on load distribution
(Ypage 233).
The overal lcenter of gravity of the load should
always be as low as possible, centered and
betwee nthe axles near the rear axle.
XObserve the legalr equirements of the country
in which you are currently driving.
Checks after loading
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is arisk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.
XSecuring luggage/loads: make sure that
the luggage and/or load is secure before
every journey and at regular intervals during a
long journey, and correct it if necessary.
XDoors/tailgate: close the sliding doors and
tailgate/door.
XTire pressure: adjust the tire pressure
according to the vehicle load (Ypage 270).
XDrivin gstyle: adapt you rdriving style
according to the vehicle load.
Load distribution
General notes
!
Excessive load sonindividual points of the
cargo floor or on the load surface impair vehi-
cle handling characteristics and could cause
damage to the floor covering.
The overal lcenter of gravity of the load should
always be as low as possible, centered and
betwee nthe axles near the rear axle.

Aq ualified specialist workshop, e.g. an author-
ized Mercedes-Benz Commercial Van Center,
will reset the service interval displaya fter the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
The prescribed service interval is based on nor- mal vehicle use. Service work will need to be
performed more frequently than prescribed if
the vehicle is operated under more arduousc on-
ditions or with higher loads. Such arduousc on-
ditions include:
Rregularc ity driving with frequent intermediate
stops
Rdriving predominantly short distances
Rfrequent operation in mountainous terrain or
on poor road surfaces
Rleaving the engine idling for long periods on a frequent basis
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for example,
replaced more frequently. Under more arduous
operating conditions, the tires must be checked more often. Further information can be obtained
at aq ualified specialist workshop, e.g. an
