WARNING
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road conditions. There is a risk of an accident. Always adapt your speed and driving style to
the vehicle's driving characteristics and to the
prevailing road and weather conditions.
Utility vehicles have a significantly higher roll-
over rate than other types of vehicles.
Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle,
and severe or fatal injury.
In a rollover crash, an unbelted person is sig- nificantly more likely to die than a person
wearing a seat belt.
You and all vehicle occupants should always
wear your seat belts. Operating safety

dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R the electrically adjustable steering wheel is
raised
R the engine is switched off and the fuel sup-
ply is cut off
R vehicles with mbrace: automatic emer-
gency call Children in the vehicle
Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better pro-
tected there.
If a child younger than 12 years and under 5 ft
(1.50 m)in height is traveling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be 52

a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
If you overfill the fuel tank, pressure may build up in the fuel tank. This could cause fuel to
spray out when the fuel pump nozzle is
removed. There is a risk of injury. The fuel
tank is full when the fuel pump nozzle first
switches off. End the refueling process.

R
the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When towing a trailer, your vehicle's handling
characteristics will be different in comparison with when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning radius
This could impair the handling characteris-
tics.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion.
General notes R
Do not exceed the legally prescribed max-
imum speed for vehicle/trailer combina-
tions in the relevant country.
This lowers the risk of an accident.
R Only install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized Mercedes-Benz Center.
R The bumpers of your vehicle are not suita-
ble for installing detachable trailer cou-
plings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R If you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to the ball coupling. i
When towing a trailer, set the tire pres-
sure on the rear axle of the towing vehicle
for a maximum load; see the tire pressure
table in the fuel filler flap (Y page 310).
You will find installation dimensions and loads
under "Technical data" (Y page 346).
The maximum noseweight of the trailer draw- bar on the ball coupling for up to 3 people is
562 lbs (255 kg). The maximum noseweight
of the trailer drawbar for more than 3 people and the maximum load for the trunk can be
found in the noseweight table (Y page 347).
However, the actual noseweight must not
exceed the value given on the trailer tow hitch or trailer identification plates. The lowest
weight applies.
Please note that when towing a trailer,
PARKTRONIC (Y page 182) and Blind Spot
Assist (Y page 178) are only available with
limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter accord- ing to the load placed on the vehicle. If nec-
essary, use a trailer with a height-adjusta-
ble drawbar.
Driving tips X
On long and steep downhill gradients,
select shift range 1,2or 3(Y page 145) in
good time.
i This also applies if you have activated
cruise control or SPEEDTRONIC.
X If necessary, shift the transfer case to LOW
RANGE (Ypage 186).
This will use the braking effect of the
engine, so that less braking will be required
to maintain the speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking,
depress the brake pedal repeatedly rather
than continuously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check 192

Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops: (Y page 24). Loading guidelines
G
WARNING
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. G
WARNING
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. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is a risk of poisoning. Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open. Driving, braking and steering characteristics
change depending on:
R type of load
R weight
R the 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 occu-
pants and luggage/load.
Do not exceed the load limit or permitted
gross vehicle weight rating (GVWR) for your
vehicle. The gross load limit and the GVWR
are specified on the vehicle identification
plate on the B-pillar of the driver's door
(Y page 336).
The load must also be distributed so that the weight on each axle never exceeds the grossaxle weight rating (GAWR) for the front and
rear axles. The specifications for GVWR and
GAWR are on the vehicle identification plate
on the B-pillar of the driver's door
(Y page 336).
Further information can be found in the
"Loading the vehicle" section (Y page 316).
Observe the following notes when transport-
ing a load:
R Position heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible. 248

nance work must be carried out more fre-
quently, for example:
R regular city driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R use in mountainous terrain or on poor road
surfaces
R if the engine is often left idling for long peri-
ods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist work- shop, e.g. an authorized Mercedes-Benz Cen-
ter. Fuel/water separator
