Safety guidelines for the seat belt,
emergency tensioning retractor and airbag
Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Light Truck Center.• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.• Airbags and ETR’s are designed to function on
a one-time-only basis. An airbag or emergency
tensioning retractor (ETR) that was activated
must be replaced.• Do not hang items such as coat hangers from
the coat hooks or handles over the door. These
items may turn into projectiles and cause head
and other injuries when curtain airbag is
deployed.
• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, or front door trim panels, and
installation of additional electrical / electronic
equipment on or near “SRS” components and
wiring. Keep area between airbags and
occupants free of objects (e.g. packages,
purses, umbrellas, etc.).

If the vehicle is parked after being driven on salt treated
roads, the braking efficiency should be tested as soon as
possible after driving is resumed while observing the
safety rules in the previous paragraph.
Winter driving
Have your vehicle winterized at your authorized
Mercedes-Benz Light Truck Center before the onset of
winter.
•Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE / CCMC class) and filling quantity,
see page 314.•Check engine coolant anticorrosion / antifreeze
concentration.
•Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent / antifreeze
which is formulated for below freezing temperatures
see page 259.
•Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.
In winter operation, the maximum effectiveness of the
antilock brake system (ABS), the four wheel electronic
traction system (4-ETS+), the electronic stability
program (ESP), and electronic brake proportioning
(EBP) can only be achieved with M+S rated radial-ply
tires and / or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.
For driving instructions using snow chains see
page 199.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with engine running.
Otherwise, deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in unconsciousness
and death.To assure sufficient fresh air ventilation, open a
window slightly on the side of the vehicle not
facing the wind.

To cancel the cruise control, briefly push lever to
position 3.
When you step on the brake pedal or the vehicle
speed drops below approximately 20 mph
(30 km / h), for example when driving upgrade, the
cruise control will be canceled.
If the cruise control cancels by itself and remains
inoperative until the engine is restarted, have the
system checked at your authorized Mercedes-Benz
Light Truck Center as soon as possible.
4Resume
If the lever is briefly pushed to position 4 when
driving at a speed exceeding approximately 20 mph
(30 km / h), the vehicle resumes the speed which
was set prior to the cancellation of the cruise
control. The last memorized speed is canceled when
the key in the steering lock is turned to position 1
or 0.Important!
Moving gear selector lever to position “N” switches the
cruise control off.
Wa r n i n g !
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.
• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.

Wa r n i n g !
The jack is designed exclusively for jacking up the
vehicle at the jack take-up brackets built into either
side of the vehicle. To help avoid personal injury,
use the jack only to lift the vehicle during a wheel
change. Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet away
from the area under the lifted vehicle. Always
firmly set parking brake and block wheels before
raising vehicle with jack.Do not disengage parking brake while the vehicle is
raised. Be certain that the jack is always vertical
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
end is fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient capacity
jackstands before working under the vehicle.

Spare wheel
In the case of a flat tire or break-down, you may
temporarily use the space-saver spare wheel, while
observing the following restrictions:
•Do not exceed vehicle speed of 50 mph (80 km / h).
•Drive to the nearest repair facility to have the flat
tire repaired or replaced as appropriate.
•Do not operate vehicle with more than one spare
wheel mounted.
For rim and tire specifications, refer to “Technical data”
on page 310.
Caution!
Exercise care when removing or installing spare wheel
to prevent personal injury.Space-saver tire (ML 55 AMG only)
Removing spare wheel (space-saver tire):
1. Open buckle of clamp, then remove cover (1).
2. Unscrew the three wheel bolts using wrench
supplied with vehicle tools, and take out space-saver
spare wheel, and remove the air pump from its
compartment.
Wa r n i n g !
The dimensions of the spare wheel are different
from those of the road wheels. As a result, the
vehicle handling characteristics change when
driving with a mounted spare wheel.
