WARNING
This Sport Utility Vehicle is designed for both
on-road and off-road use. It can go places and
perform tasks for which conventional 2-wheel
drive passenger cars are not intended. This
vehicle will handle and maneuver differently
from conventional passenger cars in driving
conditions which may occur on streets,
highways and off-road use.
This vehicle has a highe rground clearance
and a higher center of gravity than many
passenger cars. As with other vehicles of this
type, if you make sharp turns at excessive
speeds or abrupt maneuvers, the vehicle may
roll over or may go out of control and crash.
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
resul tinana ccident, rollover of the vehicle,
and severe or fatal injury.
Before you star tto drive this vehicle, read the
Operator's Manual. Take time to become
familiar with the driving characteristics of this
vehicle. Be sure you are familiar with all
vehicle controls. Learn how your vehicle
handles on different road surfaces. Do not
attempt sharp turns at excessive speeds or
abrupt maneuvers or other unsafe driving
actions that can cause loss of vehicle control.
When driving off-road or working the vehicle
hard, do not overload it. And, always wear
your seat belts at all times. In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a seat belt.
Operating safety
Important safety notes
G
WARNING
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because the
vehicle's electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function when the
engine is running. You should therefore never
turn off the engine while driving. G
WARNING
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole.
If you feel a sudden significant vibration or
ride disturbance, or you suspect that damage
to your vehicle has occurred:
R turn on your hazard warning flashers.
R slow down carefully.
R drive with caution to an area which is a safe
distance from the road.
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other 26
Introduction

If you or others come into contact with fuel,
observe the following:
R
Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medica lassistance
without delay.
R If fuel is swallowed, seek medical
assistance without delay.Don ot induce
vomiting.
R Immediately change out of clothing which
has come into contact with fuel. G
WARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline
with diesel fuel.
! Do not use gasoline to refuel vehicles with
a diesel engine. Do not use diesel to refuel
vehicles with a gasoline engine. Do not
switch on the ignition if you accidentally
refuel with the wrong fuel. Otherwise, the
fuel will enter the fuel system. Even small
amounts of the wrong fuel could result in
damage to the fuel system and the engine.
The repair costs are high. Notify a qualified
specialist workshop and have the fuel tank
and fuel lines drained completely. !
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.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.
i Flexible Fuel vehicles can be recognized
by the Ethanol up to E85 sticker on the
inside of the fuel filler flap.

When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
with when driving without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and
gradient-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
characteristics.
When towing a trailer, always adjust your
speed to the current road and weather
conditions. Do not exceed the maximum
permissible speed for yourv ehicle/trailer
combination.
General notes R
Do not exceed the legally prescribed
maximum speed for vehicle/trailer
combinations 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
suitable for installing detachable trailer
couplings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R If you no longer need the ball coupling,
remove it from the ball coupling recess.
This will reduce the risk of damage to the
ball coupling.
i When towing a trailer, set the tire
pressure on the rear axle of the towing vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y
page 419).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 454).
The maximum noseweight of the trailer
drawbar on the ball coupling is
575 lbs(261 kg) for all models (except the
model ML 350 BlueEFFICIENCY).
The maximum noseweight of the trailer
drawbar on the ball coupling is 529 lbs
(240 kg) for the model
ML 350 BlueEFFICIENCY.
The actual noseweight may not be higher than
the value which is given. The value can be
found on the trailer tow hitch or trailer
identification plates. The lowest weight
applies.
Please note that when towing a trailer,
PARKTRONIC ( Ypage 213) and Blind Spot
Assist (Y page 233) are only available with
limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter
according to the load placed on the vehicle.
If necessary, use a trailer with a height-
adjustable drawbar.
Driving tips i
Observe the information on ESP ®
trailer
stabilization (Y page 72) and on pulling
away with a trailer (Y page 160).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the
maximum permissible speed is. Observe the
legally prescribed maximum speed in the
relevant country.
For certain Mercedes-Benzv ehicles, the
maximum permissible rear axle load is
increased when towing a trailer. See
"Technical data" to find out whether this
applies to your vehicle (Y page 455). If you254

example:
R Differences in the texture
R Signs of stretching and marking
R Slight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
! Observe the following when cleaning:
R Clean artificial leather covers with a cloth
moistened with a solution containing
1% detergent (e.g. dish washing liquid).
R Clean cloth covers with a microfiber
cloth moistened with a solution
containing 1% detergent (e.g. dish
washing liquid). Rub carefully and always
wipe entire seat sections to avoid leaving
visible lines. Leave the seat to dry
afterwards. Cleaning results depend on
the type of dirt and how long it has been
there.
R Clean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible

MOExtended tires (tires with run-flat
properties)
General notes With MOExtended tires (tires with run flat
characteristics), you can continue to drive
yourv
ehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
nextt o the tire size designation, the load-
bearing capacity and the speed index
(Y page 415).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressure loss warning message
appears in the multifunction display:
R Observe the instructions in the display
messages (Y page 310).
R Check the tire for damage.
R If driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
In addition to the vehicle load, the driving
distance possible depends upon:
R speed
R road condition
R outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display. You must not exceed a maximum speed of
50 mph (80 km/h).
i
When replacing one or all tires, make sure
that you use only tires:
R of the size specified for the vehicle and
R marked "MOExtended"
If a tire has gone flat and cannot be
replaced with a MOExtended tire, a
standard tire may be used as a temporary
measure. Make sure that you use the
proper size and type (summer or winter
tire).
i Vehicles with MOExtended tires are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you
additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit may be obtained from a
qualified specialist workshop.
Important safety notes G
WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when
cornering, accelerating quickly and when
braking. There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case. 382

(Y page 382).
R Only mount tires of the correct size onto
the wheels.
R Break in new tires at moderate speeds for
the first 60 miles (100 km) .They only reach
their full performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the
latest, regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 436). MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat

you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 421). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your
vehicle to M+S tires. Using summer tires at
very cold temperatures could cause cracks to
form, thereby damaging the tires
permanently. Mercedes-Benz cannot accept
responsibility for this type of damage. M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
000A in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There
is a risk of an accident.
M+S tires with a tread depth of less than 000A
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡ (+7 †), use
winter tires or all-season tires. Both types of
tire are identified by the M+S marking. 400
