RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the rear axle load. This will pre-vent you from exceeding the permissible
gross axle weight (GAWR).
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the vehicle payload. This will
ensure that you do not exceed the permissi-
ble gross vehicle weight rating (GVWR).
Checking the vehicle and trailer weight
RMake sure the weights of the towing vehicle
and the trailer comply with the maximum per-missible values. Have the vehicle/trailer com-
bination weighed on a calibrated weigh-
bridge. The vehicle/trailer combination con-
sists of the towing vehicle including the driver,
passengers and load, as well as the loaded
trailer.
RCheck the maximum permissible gross axle
weight rating of the front and rear axles
(GAWR), the gross trailer weight (GTW), the
gross combination weight rating (GCWR) and
the noseweight of the trailer drawbar (TWR).
Trailer power supply
!
Incorrect wiring of the connector plug could,
under certain circumstances, cause malfunc-
tions in the vehicle's other electronic sys-
tems. We therefore recommend having the
connector plug wired at a qualified specialist
workshop.
!You can connect accessories with a maxi-
mum power consumption of 240 W to the
permanent power supply.
You must not charge a trailer battery using the
power supply.
Your vehicle may be equipped with various elec-
trical installations for trailer towing. Depending
on your trailer, you may need an adapter to con-
nect the electrical system of the trailer with that
of the vehicle.
The trailer socket of your vehicle is equipped at
the factory with a permanent power supply.
The permanent power supply is on the trailer
socket pin assignment 4.
Note that the permanent power supply of the
trailer is not switched off when the on-board voltage is low. This can completely discharge
the starter battery of your vehicle.
Further information on the electrical equipment
currently installed on your vehicle and on instal-
ling trailer electrics can be obtained at any quali-
fied specialist workshop.

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 (

Stowage spaces and stowage com-
partments
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 242).

Cup holder
Important safety notes
GWARNING
The cup holder cannot hold a container secure
whilst traveling. If you use a cup holder whilst
traveling, the container may be flung around
and liquid may be spilled. The vehicle occu-
pants may come into contact with the liquid
and if it is hot, they may be scalded. You may
be distracted from the traffic conditions and
you could lose control of the vehicle. There is a risk of an accident and injury.
Only use the cup holder when the vehicle is
stationary. Only use the cup holder for con-
tainers of the right size. Always close the con-
tainer, particularly if the liquid is hot.
!Only use the cup holders for containers of
the right size and which have lids. The drinks could otherwise spill.

Vehicle tool kit
General notes
Depending on the equipment version of the vehi- cle, the vehicle tool kit is:
Rin the seat base of the left front seat
Rin the rear stowage compartment
Rin the tool holder in the cargo compartment
Apart from some country-specific variants, vehi-
cles without a spare wheel are not equipped
with tire-changing tools. If your vehicle is equip-
ped with tire-changing tools, these are in the
vehicle tool kit. If the vehicle tool kit is stowed in
the driver's seat base, the jack is in a separate
holder in the cargo compartment on the right-
hand side of the vehicle next to the tailgate/rear door (
Ypage 272).
Some tools for changing a wheel are specific to
the vehicle. For more information on which tools are required and approved to perform a wheel
change on your vehicle, consult a qualified spe-
cialist workshop.
Necessary tire-changing tools can include, for
example:
Rjack
Rlug wrench
Rratchet wrench
iThe jack has a maximum weight of 7.5 kg
depending on the vehicle's equipment.
The maximum payload of the jack can be
found on the sticker on the jack itself.
The jack is maintenance-free. In the event of a malfunction, please contact a qualified spe-
cialist workshop.

Jump-starting
Important safety notes
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
GWARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
