Additional communications equipmentStowing and features
Always observe the operating instructions of
the respective manufacturer when using suit-
able load securing aids or tie downs. In par-
ticular, the information on service life.
Load securing aids and tie downs may not be
used, for example, if:
R identification marks are missing or illegible
R there are yarn breakages, damage to bear-
ing seams or other signs of tearing
R there are signs of shearing, deformation,
pinching or other damage
R there is damage to clamping or connecting
elements
Such load securing aids and tie downs are
worn; they should not be used and must be
replaced. If you use load securing aids or tie
downs which are worn, the load may not be
sufficiently secured and could cause damage
to property.
After an accident, the following must be
checked at a specialist workshop:
R Cargo compartment floor
R Load surface
R Cargo tie-down rings
R Tie downs
Otherwise, the load may not be correctly
secured the next time anything is stowed.
Even if you follow all loading guidelines, the
load increases the risk of injury in the event
of an accident. Observe the tips in the "Secur-
ing luggage/loads" (Y page 244) and "Load
distribution" (Y page 244) sections. Before loading
! The anti-slip mats cannot be used for
securing goods and must be replaced when
they show signs of:
R Permanent deformation and crushing
R Crack formation
R Cuts X
Tire pressure: check the tire pressure and
correct if necessary ( Ypage 290).
X Cargo compartment floor: clean the
cargo compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to
prevent the load from slipping.
X Place non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary. During loading
! On passenger van versions with maxi-
mum seating layout, the permissible rear
axle load would be exceeded if the full pay-
load were to be loaded in the cargo com-
partment.
X Observe the gross axle weight rating and
permissible gross vehicle weight for your
vehicle.
Take into account that your vehicle's curb
weight is increased if accessories or
optional equipment are installed. The max-
imum payload is thus reduced.
X Observe the notes on load distribution
(Y page 244).
The overall center of gravity of the load
should always be as low as possible, cen-
tered and between the axles near the rear
axle.
X Secure the load (Y page 244).
Always observe the relevant country-spe-
cific legal requirements, laws and regula-
tions. Checks after loading
G
WARNING
Combustion engines emit poisonous exhaust
gases, such as carbon monoxide. If the sliding
door or rear door is open when the engine is
running, exhaust gases can enter the vehicle
interior, especially during the journey. There
is a risk of poisoning. Loading guidelines

maximum loading capacity of the weakest
cargo tie-down point into account.
If you brake hard, for example, the forces
acting could be up to several times the
weight force of the load. Always use multi-
ple cargo tie-down points in order to dis-
tribute the force absorption. Load the
anchorages evenly.
Spread the load evenly between the cargo tie-
down points or tie-down rings.
Please also refer to the notes about qualified
specialist workshops (Y page 26).
Always observe the operating instructions or
the notes of the lashing strap manufacturer
for the operation of the lashing strap.
Information about the maximum loading
capacity of the cargo tie-down points can be
found in the "Technical data" section
(Y page 331).
As the driver, you are responsible for ensuring
that:
R The applicable requirements and guide-
lines relating to load-securing practices
must be met.
If this is not the case, this may constitute a
punishable offense, depending on local leg-
islation and any ensuing consequences.
You should therefore observe the respec-
tive legal requirements for the relevant
country.
Make sure that the load is secure before every
journey and at regular intervals during a long
journey. Correct an incorrectly or inade-
quately secured load if necessary.
You can obtain information about securing
the load correctly from the manufacturer of
the load securing aids or tie down for securing
the load.
X Fill 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 pad-
ding.
X Attach secured and stabilized loads in all
directions. Use the cargo tie-down points or cargo tie-down rings and the loading rails
in the cargo compartment or on the cargo
area.
Only use tie downs, such as lashing rods or
lashing nets and lashing straps, that have
been tested in accordance with current
standards (e.g. DIN EN).
Always use the cargo tie-down rings closest
to the load to secure it and pad sharp edges
for protection.
Loads, and heavy loads in particular, should
preferably be secured using the cargo tie-
down rings.
i Tie downs tested in accordance with cur-
rent standards (e.g. DIN EN) are available
at any qualified specialist workshop. Cargo tie-down point (example: Passenger Van)

WARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels
of the respective original containers. Always
store service products sealed in their original
containers. Always keep service products out
of the reach of children.
Brake fluid is hazardous to health. Also
observe the safety notes in the "Service prod-
ucts and capacities" section (Y page 320).G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident. You should have the brake fluid renewed at
the specified intervals.
! Brake fluid corrodes paint, plastic and
rubber. If paint, plastic or rubber has come
into contact with brake fluid, rinse with
water immediately.
Have the brake fluid renewed every 2 years
at a qualified specialist workshop. Observe
the information on brake fluid in the "Techni-
cal data" section ( Ypage 328). Check the brake fluid level regularly, e.g.
weekly or when refueling.
Checking the brake fluid level
X
Stop your vehicle as far away from traffic
as possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 250).
X Check the brake fluid level.
The brake fluid level is correct if the level is
between the MIN mark and MAX mark on
brake fluid reservoir 0043.
X Close the hood.
