Load securing aids and tie downs may not be
used, for example, if:
Ridentification marks are missing or illegible
Rthere are yarn breakages, damage to bearingseams or other signs of tearing
Rthere are signs of shearing, deformation,
pinching or other damage
Rthere 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:
RCargo compartment floor
RLoad surface
RCargo tie-down rings
RTie 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 "Securing lug-
gage/loads" (
Ypage 214) and "Load distribu-
tion" (Ypage 214) sections.
Before loading
!
The anti-slip mats cannot be used for secur-
ing goods and must be replaced when they
show signs of:
RPermanent deformation and crushing
RCrack formation
RCuts
XTire pressure: check the tire pressure and
correct if necessary (Ypage 250).
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
!
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.
XObserve the gross axle weight rating and per-
missible 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 maximum pay-
load is thus reduced.
XObserve the notes on load distribution
(Ypage 214).
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
XSecure the load (Ypage 214).
Observe the legal requirements 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 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.
Always switch off the engine before opening
the sliding door or rear door. Never drive the
vehicle when the sliding door or rear door is
open.
XSecuring loads: check that the load is secure
before every journey and at regular intervals
during a long journey, and correct if neces-
sary.
XDoors: close the sliding doors and rear doors.
XTire pressure: adjust the tire pressures
according to the vehicle load (Ypage 250).
XDriving style: adapt your driving style
according to the vehicle load.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 26).
Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The fuel injection system operates with a high
voltage. If you touch the live components, you could receive an electric shock. There is a risk
of injury.
Never touch components of the fuel injection
system when the ignition is switched on.
The live components of the fuel injection system
are, for example, the injectors.
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
If you have to carry out work in the engine com-
partment, only touch the following components:
RHood
ROil dipstick
REngine oil filler neck cap
RWasher fluid reservoir cap
RCoolant expansion tank cap
Opening the hood
!Make sure that the windshield wipers are
not folded away from the windshield. You
could otherwise damage the windshield wip-
ers or the hood.

=Engine oil filler neck cap (Ypage 220)
?Brake fluid expansion tank cap
(Ypage 223)
AWasher fluid reservoir cap (Ypage 224)
Regularly check the fluid level and the assembly
for leaks. If you detect fluid loss, e.g. oil flecks on
the vehicle parking space, consult a qualified
specialist workshop immediately.
Engine oil
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 engine oils and oil
consumption in the "Technical data" section
(
Ypage 280).
You can check the oil level in the engine:
Ron the display of the on-board computer
Rwith the oil dipstick
Checking the oil level shown in the dis-
play
If at extremely low temperatures no engine oil
level is displayed after 5 minutes, repeat the
engine oil level check after another 5 minutes.
If an oil level reading is still not displayed, check
the engine oil level with the dipstick
(
Ypage 221). Have the engine oil level checked
at a qualified specialist workshop. Only check the oil level when the engine is at
normal operating temperature.
