During loading
X
Observe the gross axle weight rating and
permissible gross vehicle weight for your
vehicle.
! On passenger van versions with
maximum seating layout, the permissible
rear axle load
would be exceeded if the full
payload were to be loaded in the cargo
compartment.
i Bear in mind that the curb weight of the
vehicle is increased by installing optional
equipment and accessories.
X Observe the information about load
distribution ( Y page 146).
X Secure the load ( Y page 146). Always
observe the relevant national regulations.
Checks after loading X
Securing loads: check that the load is
secure before every
journey and at regular
intervals during a long journey, and correct
if necessary.
X Doors: close the sliding doors and rear
doors. G
Warning
Make sure that the sliding doors and rear
doors are always closed when the engine is
running.
Exhaust fumes could otherwise enter the
vehicle interior and poison you.
X Tire pressure: adjust the tire pressures
according to the vehicle load
(Y page 281).
X Driving style: adapt your driving style
according to the vehicle load. Load distribution
The overall center
of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle. !
Excessive loads on
individual points of the
cargo floor or on the load surface impair
vehicle handling characteristics and could
cause damage to the floor covering.
On crewbuses:
X Always transport loads in the cargo
compartment.
X Always place the load against the backrests
of the rear bench seat.
X Move large and heavy loads as far towards
the front of the vehicle as possible against
the rear bench seat. Stow the load flush
with the rear bench seat.
X Always additionally secure the load with
suitable load securing aids or tie down.
i Observe the following notes:
R Do not stack
loads higher than the upper
edge of the backrests.
R Transport loads behind seats that are not
occupied.
R If the rear bench seat is not occupied,
insert the seat belts crosswise into the
buckle of the opposite seat belt. Securing loads
General notes As the driver, you are responsible for ensuring
that the cargo is secured against sliding,
tipping, rolling or falling. This applies to
general traffic situations as well as evasive
maneuvers or full brake application and on
poor stretches of road.
If your load
is not secured in accordance with
applicable requirements and guidelines
regarding the securing of loads, you may be
liable to prosecution, depending on the local
legislation and the consequences of
inadequately secured loads.
You should therefore observe the respective
legal requirements for the relevant country.
Check that the load is secure before every
journey and at regular intervals during a long 146

Operation
The windshield wipers may otherwise move
and injure you.
X Turn the key to position 0 in the ignition
lock or remove it.
! Do not fold the windshield wipers away
from the windshield unless the hood is
closed. Otherwise, you could damage the
hood.
X Fold the wiper arms away from the
windshield until you feel them engage.
X Clean the windshield and the wiper blades.
X Fold the windshield wipers back again
before switching on the ignition.
Headlamps Wipe the headlamp lenses with a wet sponge.
! Only use washer
fluid which is suitable for
plastic lamp lenses. Unsuitable washer
fluid could damage the plastic lamp lenses
of the headlamps.
Therefore, do not use:
R dry cloths
R abrasive products
R solvents
R cleaning products containing solvents
You could otherwise scratch or damage the
surface of the lenses.
Sliding door Clean the contact plates and the tips of the
contact pins around the sliding door with
water, shampoo and a soft cloth.
Do not oil or grease the contact plates and
contact pins.
Remove foreign objects. Power washers
! Maintain the following minimum
distances between the high-pressure
nozzle and the object being cleaned:
R approximately 2.2 ft (70 cm)
when using
round-jet nozzles
R approximately 1 ft (30 cm) when using
25° flat-spray jets and concentrated-
power jets
Keep the water jet moving while cleaning.
To avoid causing damage, do not point the
water jet directly at:
R door joints
R brake hoses
R electrical components
R plug connections
R seals
R the drive train, especially not at the
intermediate bearing of the propeller
shaft
R the rear-view camera or the microphone
opening on the bottom of the rear-view
camera. Keep a minimum distance of
1.6 ft (50 cm). G
Warning
Do not
use round-jet nozzles to clean the tires.
The pulsating water jet can cause damage to
the substructure of
the tires that is not visible
from the outside. This type of damage only
becomes noticeable at a much later stage and
can cause the tires to burst. This could cause
you to lose control of the vehicle, resulting in
an accident and injuring yourself or others.
Replace damaged tires immediately. Automatic car wash
If the vehicle is very dirty, prewash it before
you put it through an automatic car wash. G
Warning
If a wax preservative is applied after the
vehicle is washed,
you should remove the wax164

from the windshield and the wiper blades to
prevent smearing.
Smears
impair the driver's
view, and their effect is made worse in
conditions where visibility is poor (e.g. glare,
mist, darkness, snow). You may therefore fail
to recognize dangers, or not recognize them
in time, and thereby cause an accident.
! Make sure that the automatic car wash is
suitable for the size of the vehicle.
Before washing the vehicle in an automatic
car wash, fold in the exterior mirrors and
remove the radio/telephone antenna.
Otherwise, the exterior mirror, antenna or
the vehicle itself could be damaged.
Make sure that the antenna is installed and
that the exterior mirrors are fully folded out
again when you leave the automatic car
wash.
! Make sure that the side windows are
completely closed, that the ventilation/
heating is switched off and that the
windshield wiper switch is set to 0.
Otherwise, the rain/light sensor could be
activated, triggering unintended wiper
movements. This can cause damage to the
vehicle.
After putting the vehicle through an
automatic car wash, wipe off wax from:
R the rear-view camera lens ( Y page 163)
R the windshield and the wiper blades. This
prevents smears and reduces wiping noise
which can be caused by residue on the
windshield. Cleaning the engine
! Water must not
enter intake or ventilation
openings. When cleaning with high
pressure water or steam cleaners, the
spray must not be aimed directly at
electrical components or the terminals of
electrical lines. Preserve the engine after the engine has
been cleaned.
Protect
the belt drive system
from exposure to the preservative agent. Alloy wheels
Clean the alloy wheels regularly.
! Do not use
any acidic or alkaline cleaning
agents. They can cause corrosion on the
wheel bolts (wheel nuts) or the retainer
springs for the wheel-balancing weights. After driving off-road or on
construction sites
G
Warning
Dirt on the vehicle can affect road and
operating safety.
It can specifically result in the following
dangers:
Stone impact. Stones trapped between the
tires can be thrown out while driving. This
could injure other
road users or damage other
vehicles (especially windscreens).
Risk of skidding. Dirt and mud on the tires/
on the road reduce the grip of the tires on the
road. This especially applies when the surface
is wet. The vehicle could then start to skid.
Risk of injury. Dirt and mud on the steps and
entrance can make the steps unsafe. This
could cause you to slip off the steps and be
injured.
For this reason, you should always clean your
vehicle carefully after driving off-road or on
construction sites before driving on public
roads. Observe the corresponding safety
notices in this chapter if you use a power
washer or an automatic car wash to clean your
vehicle.
