Searching for and authorizing (connect-
ing) a mobile phone
Before using your mobile phone with the multi-
media system for the first time, you will need to
search for the phone and then authorize (con-
nect) it. Depending on the mobile phone, author-ization either takes place by means of Secure
Simple Pairing or by entering a passkey. The
multimedia system automatically makes the
procedure that is relevant for your mobile phone
available. The mobile phone is always connec-
ted automatically after authorization. Further
information on using a mobile phone with the
multimedia system (see the Digital Operator's
Manual).
If the multimedia system does not detect your
mobile phone, this may be due to particular
security settings on your mobile phone (see the
manufacturer's operating instructions).
Only one mobile phone can be connected to the
multimedia system at any one time.

Loading guidelines
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
GWARNING
If you distribute the load unevenly in the vehi- cle, the handling as well as the steering and
braking characteristics are severely affected.
There is a risk of an accident.
Distribute the load evenly in the vehicle.
Secure the load to prevent it from slipping.
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the rear
door is open when the engine is running, par-
ticularly if the vehicle is moving, exhaust
fumes could enter the passenger compart-
ment. There is a risk of poisoning.
Turn off the engine before opening the rear
door. Never drive with the rear door open.
Driving, braking and steering characteristics
change depending on:
Rtype of load
Rweight
Rthe center of gravity of the load
You should therefore load your vehicle as shown
in the illustrations.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, accessories installed, vehicle occupants
and luggage/load.
Do not exceed the load limit or permitted gross
vehicle weight rating (GVWR) for your vehicle.
The load limit and GVWR are given on the vehicle
identification plate found on the driver's door B-
pillar.
Furthermore, the load must be distributed in
such a way that the weight on each axle never
exceeds the gross axle weight rating (GAWR) for
the front and rear axles. The relevant GVWR and
GAWR information can be found on the vehicle
identification plate on the driver's side B-pillar.
Further information can be found in the "Loading
the vehicle" section (
Ypage 266).
Observe the following notes when transporting
a load:
RPosition heavy loads as far forward as possi-
ble and as low down in the cargo compart-
ment as possible.
RTransport loads when possible in the cargo
compartment. You should only use the cargo
compartment enlargement if the load does
not fit in the cargo compartment.

RAlways place the load against the backrests ofthe front seats or rear seats.
RUse the cargo tie-down rings and the parcel
nets to transport loads and luggage.
RUse cargo tie-down rings and fastening mate-
rials appropriate for the weight and size of theload.
If the rear bench seat is not occupied:
XInsert the belt tongue on the outer seat belts
into the buckle of opposite seat belt :.
XSecure the load with sufficiently strong and
wear-resistant tie downs.
XPad sharp edges for protection.

Important safety notes
GWARNING
If you transport objects in the vehicle interior
and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of
an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction.
RAlways stow objects in such a way that they
cannot be tossed about in these or similar
situations.
RAlways make sure that objects do not pro-
trude out of the stowage spaces, luggage
nets or stowage nets.
REnsure that closable stowage spaces are
shut before beginning your journey.
RAlways stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or large objects in
the cargo compartment.
Observe the loading guidelines (
Ypage 209).

Securing loads
Important safety notes
Distribute the load on the cargo tie-down rings
evenly.
Do not tamper with or repair cargo tie-down
points, cargo tie-down rings or tie downs. Have
maintenance work as well as modifications,
installations and conversions carried out at a
qualified specialist workshop (
Ypage 27).
Observe the following notes on securing loads:
RObserve the loading guidelines (Ypage 209).
RSecure the load using the cargo tie-down
rings.
RDistribute the load on the cargo tie-down
rings evenly.
RDo not use elastic straps or nets to secure a
load, as these are only intended as an anti-slip
protection for light loads.
RDo not route tie-downs across sharp edges or corners.
RPad sharp edges for protection.
ROnly use tie downs that have been checked in
accordance with applicable standards, e.g.
lashing nets or lashing straps.
RFill the spaces between the load and the
cargo compartment walls and the wheel
housing in a form-locking way. Only use
dimensionally stable transportation aids for
this, such as chocks, wooden fixings or pad-
ding.

RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
RUse of engine oil additives
!Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd the amount of engine oil required.
Observe the specifications in the on-board com-
puter when doing so or fill carefully to the max-
imum mark on the oil dipstick.
The difference between the minimum mark and
the maximum mark on the oil dipstick is approx-
imately 2.1 US qt (2.0 l).
XReplace cap :on the filler neck and tighten
clockwise.
Ensure that the cap locks into place securely.
