cluster displayPractical hints Car care Index Engine oil level indicator
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after stopping
the engine, allowing for the oil to return to the oil pan.
Turn the key in steering lock to position 2 and wait until
the display “––––––” appears in the odometer display
field.
Within 1 second press button (1) twice.The following messages are available:
“OIL i.O”
No oil needs to be added.
“–1.0 L”
“–1.5 L”
“–2.0 L”
Add oil to upper (max) mark of the dipstick.
See page 233 for instructions on adding engine oil.
“OIL HI”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The display “––––––” flashes in the odometer display
field if a proper oil level check cannot be performed. The
engine oil level check can be repeated after a short time.
Perform the engine oil level check with the dipstick, if it
cannot be completed via the odometer display field.
See page 233.
In this case we recommend that you have the system
checked at a Mercedes-Benz Light Truck Center.

Te ch n ica l

cluster displayPractical hints Car care Index 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 292.
•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 237.
•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 179.
Deep water
Caution!
Do not drive through flooded areas or water of unknown
depth. Before driving through water, determine its
depth. It should not be deeper than approximately
20 inches (50 cm).
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.

Te ch n ica l

cluster displayPractical hints Car care Index Off-Road driving
Familiarize yourself with the vehicle characteristics and
gear changing before you attempt any difficult terrain
off-road driving. We recommend that you start out with
easy off-road travel.
Please read this chapter carefully before you begin
off-road travel.
Special driving features are available for specific kinds
of operation:
•LOW RANGE mode, see page 209
•LOW RANGE - ABS, see page 202
•LOW RANGE - 4-ETS+, see page 204
•LOW RANGE - ESP, see page 208
Engage the LOW RANGE mode before driving under
off-road conditions. For switching LOW RANGE mode on
and off see page 209.
Fasten items being carried as securely as possible, see
page 136.
We recommend to keep doors, liftgate, windows, and
roof closed whenever driving in off-road mode.Important!
Adjust vehicle speed to condition of terrain. The more
uneven, rutty and steeper the terrain, the lower the
speed should be.
Watch out for obstacles, such as rocks, holes,
tree-stumps, ruts.
Be especially careful when driving in unknown
territory. Eventually get out of the vehicle and scout the
path you intend to take.
Continuous and speedy driving in sandy soil overcomes
the vehicle rolling resistance, and helps to prevent the
vehicle from sinking into the ground.
Do not initiate jumps with the vehicle. It interrupts the
forward momentum of the vehicle.
Sand, dirt, mud and other material having friction
property, can cause exceptional wear and tear as well as
failure of the brakes.
In this case the brakes may be less effective or even fail
when you most need them. Always clean and check the
brakes following each off-road trip.

Checklist before off-road driving
•Tires: Check the tread depth and maintain specified
tire pressure (see tire pressure label inside the fuel
filler flap). Check tires for possible damage and
remove foreign objects. The valve caps must be
mounted.
•Rims: Dented or bent rims can cause tire pressure
loss and damage the tire beads. For this reason
change rims before driving off-road.
• Vehicle tool kit: Check if the vehicle jack is
functional. In all cases take the vehicle tool kit, a
strong tow rope, a shovel and a small plank (to put
under the vehicle jack on sandy soil) with you.Driving in steep terrain
Slope angle:
126° (ML 320 and ML 430)
23° (ML 55 AMG)
226° (ML 320 and ML 430)
21° (ML 55 AMG)
Switch to LOW RANGE mode before starting to drive up
or down steep inclines, see page 209.
Maximum vehicle climbing ability is a 60% grade.

cluster displayPractical hints Car care Index Returning from off-road driving
Off-road driving increases strain on the vehicle.
We recommend that you inspect the vehicle for possible
damage after each off-road trip. Recognizing any
damage and a subsequent timely repair reduces the
chance of a possible breakdown or accident later on.
Proceed as follows:
•Switch off the LOW RANGE mode, see page 209.
•Remove excessive dirt from tires, wheels, wheel
housings, and underbody. For instance, after driving
in mud, clean the radiator, chassis, engine, brakes,
and wheels from extreme dirt, using a strong jet of
water.
•Inspect frame, oil pan, brake hoses, etc., as well as
vehicle underbody for possible damage.
•Check tires for possible damage, clean all exterior
lamps, and conduct a brake test.•Check for brush or branches caught in the
undercarriage. They could increase the possibility of
a fire, as well as cut fuel and / or brake lines,
puncture rubber bellows of the axles or drive shafts.
Wa r n i n g !
If you feel a sudden significant vibration or ride
disturbance, or you suspect that possible damage to
your vehicle has occurred, you should turn on the
hazard warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the roadway.Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Light Truck
Center or tire dealer for repairs.

213 What you should know at the gas station
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Leaving the engine running and the fuel cap open can
cause the “CHECK ENGINE” lamp to illuminate.
Fuel tank capacity approximately 19.0 US gal (72.0 l).
This includes approximately 3.2 US gal (12.0 l) reserve.
Use premium unleaded gasoline: Posted Octane
Index 91 (Average of 96 RON / 86 MON).
•Engine oil
Engine oil level check, see page 89 and page 233.
Fill quantity between upper and lower dipstick
marking level: 2.1 US qt (2.0 l).
Recommended engine oils, see Approved Service
Products sheet.• Coolant
For normal replenishing, use water (potable water
quality).
For further information (e.g. anticorrosion/
antifreeze), see page 292.
• Spark plugs
Approved spark plugs, see page 290.
• Tire pressure
For tire pressure, refer to tire pressure label inside
the fuel filler flap. See page 250 for further details.
• Air conditioner
R-134a refrigerant and special PAG lubricant, see
page 294.
Wa r n i n g !
Overfilling of fuel tank may result in creating
pressure in the system which could cause a gas
discharge such as the gas spraying back out upon
removing the filler nozzle which could cause
personal injury.
