Index

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.

! Rinse surfaces that have come into
contact with DE Fimmediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clea nit. DEF
residues crystallize after time and
contaminate the affected surfaces.
! DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to
the fuel tank, this can lead to engine
damage.
For further information on DEF, see
(Y page 448).

Important safety notes
G
WARNING
If flammable materials such as leaves, grass
or twigs are exposed to prolonged contac tto
parts of the exhaust system that heat up, they
could ignite. There is a risk of fire.
Park the vehicle so that no flammable
materials come into contact with parts of the
vehicle which are hot. Take particular care not
to park on dry grassland or harvested grain
fields. G
WARNING
If you switch off the ignition while driving,
safety-relevant function sare only available
with limitations, or not at all.T his could affect,
for example, the power steering and the brake
boosting effect.Y ou will require considerably more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
G
WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R starting the engine.
They could also operate the vehicle's
equipment. There is a risk of an accident and
injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
! Always secure the vehicle correctly
against rolling away.O therwise, the vehicle
or its drivetrai ncould be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R the transmission must be in position Pand
the SmartKey must be removed from the
ignition lock.
R on steep uphill or downhill gradients, turn
the front wheels towards the curb.
R on steep uphill or downhill gradients, the
front axle of an empty vehicle must be
secured, for example with awheel chock.
R on steep uphill or downhill gradients, the
rear axle of a laden vehicle must be
additionally secured, for example with a
wheel chock. Parking

plates and those for the towing vehicle under
"Technical data" (Y
page 455).
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
