Storage pockets
GWARNING
Storage bags are intended for storing light-
weight items only.
Heavy objects, objects with sharp edges or
fragile objects may not be transported in the
storage bag. In an accident, during hard brak-
ing, or sudden maneuvers, they could be
thrown around inside the vehicle and cause
injury to vehicle occupants.
Storage bags cannot protect transported
goods in the event of an accident.
The stowage pockets are located on the rear
side of the front seats.
Stowage nets
The stowage net is in the front-passenger foot-
well.
Observe the loading guidelines (

Important safety notes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for-
wards, e.g. when braking suddenly or in the
event of an accident.
RThe vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
RObjects or loads in the trunk/cargo com-
partment cannot be restrained by the seat
backrest.
There is an increased risk of injury.
Before every trip, make sure that the seat
backrests and the rear bench seat/rear seat
are engaged.

Securing cargo
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 23).
Observe the following notes on securing loads:
RSecure the load using the cargo tie-down
rings.
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.

12 V sockets
General notes
!If you are simultaneously using all three
sockets in the vehicle, make sure that you do
not exceed the maximum current draw of
45 A. Otherwise, you will overload the fuses.
The sockets can be used for accessories with a
maximum current draw of 180 W (15 A) each,
e.g. bulbs or chargers for mobile phones.
If you use the sockets for long periods when the
engine is switched off, the battery may dis-
charge.

115 V socket
GWARNING
The 115 VAC power socket operates on high
voltage. Use the 115 V AC power socket in the
vehicle with the same caution and care that
you would take with power sockets at home.
Keep fluids away from the 115 V AC power
socket. Do not use liquids or sharp tools to
clean the power socket. Keep the cover of the
115 V AC power socket closed when not in
use. Otherwise, you could suffer an electric
shock and beseriously or even fat allyinjured.
Features223
Stowage and features
Z
GWARNING
Any device that you connect must have a suit-
able plug and meet U.S. standards. Never pull at a cable to disconnect a plug from a 115 V
AC power socket. Never use a damaged con-
nection cable. The 115 V AC power socket
must never be connected to another 115 V AC power source. Do not use a converter with an
earthed plug for the 115 V AC power socket.
This could cause serious injury to you and/or
other people.
GWARNING
If the 115 V AC power socket is damaged or
pulled out of the trim, do not use or touch the
115 VAC power socket. The use of a 115 VAC
power socket that has been damaged or
pulled out of the trim could cause serious
injury to you or others.
115 V power socket :provides an AC voltage
of 115 Vso that small electronic devices can be
connected. These devices, such as games con-
soles, chargers and laptops, should not con-
sume more than a maximum of 150 W alto-
gether.
Requirements for operation of these devices:
Rthe 12 V sockets in the rear compartment and
the cargo compartment are operational
(
Ypage 223).
Rthe plug of the electronic device is plugged
into 115 V power socket :.
Rthe on-board power supply is within a permis-
sible voltage range.
Rthe electronic device's maximum power out-
put does not exceed 150 W.
XOpen flap =.
XSwitch on the ignition.
XInsert the plug of the electronic device into
115 V power socket :.
Indicator lamp ;lights up.
If indicator lamp ;does not light up, please
read the section on malfunctions.
XTo turn off: disconnect the plug from 115 V
power socket :.
Ensure that you do not pull on the cord.
XClose flap =.
Possible causes of malfunctions:
Rthe on-board power supply is not within a per-
missible voltage range.
Rthe temperature of the DC/AC converter is
temporarily too high.
Rsome small electronic devices have a con-
stant nominal power of less than 150 W, but a
very high switch-on current. In that case,
there is a possibility that these devices will
not function properly as 115 V socket :is
not able to provide a high enough current.
XIf indicator lamp ;still does not light up,
contact a qualified specialist workshop.
