Permissible trailer loads and trailer
drawbar noseweights
Weight information !
For vehicles with a permissible gross vehi-
cle weight of 6614 lbs (3000 kg), the per-
missible gross combination mass is less
than the sum of the permissible gross vehi-
cle weight plus the permissible trailer load.
Exceeding the permissible gross combina-
tion mass can lead to damage to the drive-
train, to the transmission or to the trailer
hitch.
If either the vehicle or the trailer is fully
laden, the permitted gross vehicle weight or
the permitted trailer load values are reduced
accordingly. In this case, you may only parti-
ally load the trailer or the vehicle.
The gross trailer weight (GTW) is calculated by
adding the weight of the trailer to the weight
of the load and equipment. If the trailer is
installed with a separate functional braking
system, then the maximum gross trailer weight
is 5000 lbs (2268 kg). G
WARNING
If you tow a trailer without a separate func-
tional braking system and a gross trailer
weight (GTW) of more than

1635 lbs
(750 kg), then the vehicle brake system may
overheat. This increases the braking dis-
tance and the brake system may even fail.
There is an increased risk of accident and
injury, possibly even fatal.
Always use a trailer with a separate func-
tional braking system when towing a trailer
with a gross trailer weight (GTW) of more
than 1635 lbs (750 kg).
The maximum noseweight of the trailer draw-
bar on the ball coupling is 500 lbs (227 kg).
The actual noseweight may not exceed the
value given on the identification plates of the
trailer tow hitch or the trailer. If the values
vary, the lowest value always applies.
The gross combination weight rating (GCWR) is
calculated by adding the gross weight of the
trailer to the gross vehicle weight including a
driver's weight of approximately 150 lbs
(68 kg). The permissible Gross Combination Weight Rating is vehicle-specific and depends
on the equipment level.
When driving with a trailer, you should not
exceed the permitted Gross Combination
Weight Rating (GCWR).
The permissible values, which must not be
exceeded, can be found in your vehicle docu-
ments and on the trailer tow hitch type plates
for the trailer and the vehicle (
Y page

304).
The basic values approved by the manufac-
turer can also be found in the "Technical data"
section ( Y page 315). If the values vary, the
lowest value always applies.
Loading a trailer !
Utilize the maximum permissible nose-
weight as fully as possible. Do not allow the
weight to fall below the minimum permissi-
ble noseweight, otherwise the trailer may
come loose.
R The load must be distributed over the vehi-
cle and the trailer so as not to exceed either
the maximum permissible values for the
gross vehicle weight rating (GVWR) and
gross trailer weight (GTW), the gross combi-
nation weight rating (GCWR), nor the maxi-
mum permissible gross axle weight rating
(GAWR) and trailer drawbar noseweight rat-
ing of your vehicle.
R Add the drawbar noseweight on the ball
coupling (TWR) to the rear axle load. This
will prevent you from exceeding the permis-
sible gross axle weight (GAWR).
R Add the drawbar noseweight on the ball
coupling (TWR) to the vehicle payload. This
will ensure that you do not exceed the per-
missible gross vehicle weight rating (GVWR).
Checking the vehicle and trailer
weight R
Make sure the weights of the towing vehicle
and the trailer comply with the maximum
permissible values. Have the vehicle/trailer
combination 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.
R Check 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) 172

Disconnecting and removing
G
WARNING
During the charging process, a battery pro-
duces hydrogen gas. If a short circuit occurs
or sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
R Never place metal objects or tools on a
battery.
R It is important that you observe the
described order of the battery terminals
when connecting and disconnecting a bat-
tery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
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
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
! You should have all work involving the bat-
tery carried out at a qualified specialist
workshop.
If, in exceptional circumstances, you need
to disconnect the battery yourself, please
make sure that:
R Secure the vehicle to prevent it from roll-
ing away.
R You have switched off the engine and
removed the key. Make sure the ignition
is switched off. Check to see that there
are no indicator lamps lighting in the instrument cluster. Electronic compo-
nents such as the alternator may other-
wise be damaged.
R After the battery has been disconnected,
the parking brake is automatically
engaged. You can then no longer move
the vehicle.
R For vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. You can
then no longer move the vehicle.
R You have first removed the negative ter-
minal and then the positive terminal.
Never mix up the terminal clamp discon-
nection/connection order and never mix
up the terminal clamps. The vehicle's
electronics may otherwise be damaged.
The battery and the cover of the positive ter-
minal clamp must be installed securely dur-
ing operation. Seat base (example: right-hand front seat)
The following description on disconnecting
and removing the battery is based upon the
example of the starter battery in the seat base
of the driver's seat. The additional battery is
disconnected and removed in the same way as
the starter battery. The auxiliary battery is
located in the seat base of the left-hand front
seat.
X Switch off all electrical consumers.
X Switch off the engine and remove the key
from the ignition lock.
X Open the front door on the right-hand side.
i To disconnect or remove the additional
battery, open the left-hand front door. The
auxiliary battery is located in the seat base
of the left-hand front seat. 260
