Also observe the safety information in the load-
ing directions (Ypage 242).
XFill spaces between the load and the cargo
compartment walls or wheel housings (form-
locking). Use rigid load securing aids, such as
wedges, wooden fixings or padding.
XAttach secured and stabilized loads in all
directions to the cargo tie-down rings and the
guide rails in the rear.
Only use tie downs, such as lashing nets and
lashing straps, that have been tested in
accordance with current standards.
When securing a load, always use the closest cargo tie-down rings and pad sharp edges for
protection.
Cargo tie-down points (example: Cargo Van)
Fixed cargo tie-down points on the floor
:
Guide/load rails
;Cargo tie-down rings
If your vehicle is equipped with guide/loading
rails :in the floor, you can place lashing rods
directly in front of and behind the load. The lash-
ing rods directly absorb the potential shifting
forces.
Securing loads on the cargo compartment floor
by lashing them down is only recommended for lightweight loads. Place non-slip mats (anti-slip
mats) under the load to increase load security.
Lashing straps
Important safety notes
GWARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction, brak- ing maneuvers or an accident:
Rthe cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
Rthe load may not be restrained.
This may cause the load to slip, tip over or be
tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads.
!Observe the information on the maximum
loading capacity of the individual cargo tie-
down points.
If you use several cargo tie-down points to
secure a load, you must always take the max-
imum loading capacity of the weakest cargo
tie-down point into account.
If you brake hard, for example, the forces act-
ing could be up to several times the weight
force of the load. Always use multiple cargo
tie-down points in order to distribute the force absorption. Load the anchorages evenly.
Always observe the operating instructions or the
notes of the la shing strap ma

nufacturer for the
operation of the lashing strap.
Securing loads on the cargo compartment floor
by lashing them down is only recommended for
lightweight loads. Place non-slip mats (anti-slip
mats) under the load to increase load security.

General notes
!Engine oil gets dirty in the course of opera-
tion and its quality and volume are gradually
diminished. Regularly check the oil level, and
top up or have it replaced as needed.
Observe the information on approved engine
oils and oil consumption under "Service prod-
ucts and capacities" (
Ypage 307). You can check the oil level in the engine:

Maintenance and care

RIt is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
!You should have all work involving the bat-
tery carried out at a qualified specialist work-
shop.
If, in exceptional circumstances, you need to
disconnect the battery yourself, please make
sure that:
RSecure the vehicle to prevent it from rolling
away.
RYou have switched off the engine and
removed the key. Make sure the ignition is
switched off. Check to see that there are no
indicator lamps lighting in the instrument
cluster. Electronic components such as the
alternator may otherwise be damaged.
RAfter the battery has been disconnected,
the parking brake is automatically
engaged. You can then no longer move the
vehicle.
RFor vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. You can
then no longer move the vehicle.
RYou have first removed the negative termi- nal and then the positive terminal. Never
mix up the terminal clamp disconnection/
connection order and never mix up the ter-
minal clamps. The vehicle's electronics
may otherwise be damaged. The battery and the cover of the positive ter-
minal clamp must be installed securely during
operation.
Seat base (example: right-hand front seat)
The following description on disconnecting and
removing the battery is based upon the example
of the starter battery in the seat base of the
driver's seat. The additional battery is discon-
nected and removed in the same way as the
starter battery. The auxiliary battery is located in the seat base of the left-hand front seat.
XSwitch off all electrical consumers.
XSwitch off the engine and remove the key
from the ignition lock.
XOpen the front door on the right-hand side.
iTo disconnect or remove the additional bat-
tery, open the left-hand front door. The auxil-
iary battery is located in the seat base of the
left-hand front seat.

Maintenance and care

installed in the vehicle. The vehicle's elec-
tronics system may otherwise be damaged.
!Only charge the battery using the jump-
starting connection point.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. Only this device permits the charging
of the battery in its installed position. Contact an
authorized Mercedes-Benz Commercial Van
Center for information and availability. Read the
operating instructions for your charger before
charging the battery.
Recharge the battery more frequently if you use the vehicle mainly for short trips and/or drive at
low outside temperatures.
Only charge the installed battery with a battery
charger that has been tested and approved by
Mercedes-Benz, using the jump-start connec-
tion point in the engine compartment.
XConnect the battery charger to the positive
terminal and ground terminal in the same
order as when connecting the donor battery in
the jump-starting procedure (
Ypage 272).
iIf a battery is not installed and not in service,
you should charge it every three months. This
will counter self-discharging and prevent bat-
tery damage.
Care
!
Dirty battery clamps and battery surfaces
cause leak currents which lead to the batter-
ies discharging.
!Do not use cleaning agents containing fuel.
Cleaning agents containing fuel corrode the
battery housing.
!If dirt gets into the battery cell, battery self-
discharge will increase and the battery may
be damaged.
The following points on battery care must be
observed:
XRegularly check the battery terminals and the
fastening of the negative cable to the chassis
to ensure that they are firmly seated.
XAlways keep the battery terminals and battery
surfaces clean and dry.
XLightly grease the undersides of the battery
terminals with acid-resistant grease.
XOnly clean the battery casing with a commer-
cially available cleaning product.

Notes on care
GWARNING
If you use openings in the bodywork or
detachable parts as steps, you could:
Rslip and/or fall
Rdamage the vehicle and cause yourself to
fall.
There is a risk of injury.
Always use secure climbing aids, e.g. a suita-
ble ladder.
!Do not use the lower sliding door guide (car-
riage) as a step. Otherwise, you could damage
the paneling and/or the sliding door mecha-
nism.
!For cleaning your vehicle, do not use any of
the following:
Rdry, rough or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
