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 "Securing
luggage/loads" (Y page 242) and "Load dis-
tribution" (Y page 242) 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 (Y page 288).
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 242).
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 242).
Observe the legal requirements of the
country in which you are currently driving. Checks after loading

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

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
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions
relevant to safety.

workshops (Y page 25). Engine compartment
Hood
Important safety notes G
WARNING
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. G
WARNING
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. G
WARNING
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:
R switch off the ignition
R never reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
R remove jewelry and watches
R keep items of clothing and hair, for exam-
ple, away from moving parts G
WARNING
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 sys-
tem are, for example, the injectors. G
WARNING
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
compartment, only touch the following com-
ponents:
R Hood
R Oil dipstick
R Engine oil filler neck cap
R Washer fluid reservoir cap
R Coolant 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
wipers or the hood. 248

General notes !
Engine oil gets dirty in the course of oper-
ation and its quality and volume are gradu- ally diminished. Regularly check the oil
level, and top up or have it replaced as nee-
ded.
Observe the information on engine oils and oil
consumption in the "Technical data" section
(Y page 322).
You can check the oil level in the engine:
R on the display of the on-board computer
R with 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
(Y page 251). Have the engine oil level
checked at a qualified specialist workshop.
Only check the oil level when the engine is at
normal operating temperature.

For vehicles with a red oil dipstick, only checkthe oil level when the engine is at normal
operating temperature:
X Stop your vehicle as far away from traffic as
possible on level ground.
X Secure the vehicle to prevent it from rolling
away.
X Switch off the engine.
X Wait 5 minutes.
For vehicles with a yellow oil dipstick, only

X Stop your vehicle as far away from traffic as
possible on level ground.
X Secure the vehicle to prevent it from rolling

X Open the hood (Y page 248).
X Pull out oil dipstick 0043.
X Wipe oil dipstick 0043using a lint-free cloth.
X Insert oil dipstick 0043back into the guide
tube as far as it will go and remove it again.
If the level is between minimum mark 0087
and maximum mark 0044, the oil level is cor-
rect.
X If the oil level has dropped to or below min-
imum mark 0087, open cap 0085and add
engine oil (Y page 252).
The difference in quantity between
marks 0044and 0087is approximately

At outside temperatures between 32 ‡
(–0 †) and 86 ‡ (30 †), the oil level can be

X Add engine oil (Y page 252)
or X Have engine oil siphoned off.
Add engine oil G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool down and
thoroughly clean the engine oil off the com-
ponents before starting the engine.
! The alternator is located below the engine
oil filler neck. If engine oil spills onto the
alternator, there is a danger of alternator
damage. Be very careful when adding
engine oil. H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to the environment.
! Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off.
! Do not use any additives in the engine oil.
This could damage the engine.
