G WARNING
The brake system continues to function normally, but without the

brakes are applied with maximum force.
This causes steerability and braking to be greatly impaired.

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 func-
tions. This also applies to systems and func-
tions relevant to safety.
Read the information on qualified specialist
workshops (Y page 26). Loading guidelines
Important safety notes
G
WARNING
As a result of improperly placed or unevenly
distributed loads, the center of gravity of the
load being transported may be too high or too
far back. This can significantly impair handling
as well as steering and braking characteris-
tics. There is a risk of an accident.
Always make sure that the center of gravity of
the load is:
R between the axles
and
R as low as possible, near the rear axle. G
WARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be thrown
about, striking vehicle occupants. This also
applies to:
R luggage or loads
R a rear bench seat which has been removed
and is being transported in the vehicle in an
exceptional case.
There is a risk of injury, particularly in the
event of braking maneuvers or abrupt
changes in direction.
Always stow objects in such a way that they
cannot be tossed about. Before traveling,
secure objects, luggage or loads to prevent them slipping or tipping over. If you remove a
rear bench seat, it is advisable to store it out-
side the vehicle.
G
WARNING
When the permissible wheel loads, axle loads
and/or the maximum permissible gross vehi-
cle weight are exceeded, driving safety is
compromised. The handling as well as steer-
ing and braking characteristics may be signif-
icantly impaired. Overloaded tires may over-
heat, causing them to burst. There is a risk of
an accident.
When transporting a load, always observe the
permissible wheel loads, axle loads and the
maximum permissible gross vehicle weight
for the vehicle (including occupants). G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character-
istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.
There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
! If you are using a roof carrier, observe the
maximum roof load and maximum roof car-
rier load.
You will find information about the maximum
roof load in the "Technical data" section
(Y page 331 )and information about roof car-
riers in the "Carrier systems" section
(Y page 247).
R Do not stack luggage or loads higher than
the backrests.
R Stow objects preferably in the cargo com-
partment.
R When transporting luggage, always use the
cargo tie-down rings and a parcel net, if
present.
R Use cargo tie-down rings and fasteners
which are suitable for the weight and size
of the load. 242
Loading guidelinesTransporting loads
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
If the hood is unlatched, it could tip forward
during rapid deceleration of the vehicle and
hit persons or objects within its path. There is
a risk of an accident and injury.
Therefore, always make sure that the hood is
closed and locked completely before driving
off.

X Lift the hood slightly.
X Press support strut 0087towards the back.
X Lower the hood and allow it to fall with
momentum from a height of approximately
1 ft (30 cm).
The hood locks audibly.
X Check that the hood is correctly locked.

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
needed.
Observe the information on engine oils and oil
consumption in the "Technical data" section
(Y page 326).
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.
Have the oil level display checked at a quali-
fied specialist workshop.
Only check the oil level when the engine is at
normal operating temperature.
X Park the vehicle on a level surface.
X Switch off the engine.
X Wait for five minutes.
