WARNING
Avoid contact with fuels.
It is hazardous to yourh ealth if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
WARNING
Do not use petrol to refuel a diesel tank .Never
mix diesel with petrol. Doing so could damage
the fuel system and the engine. The vehicle
could also catch fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
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 adding fuel from a fuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.
Further information on fuel and on fuel grades
can be found in the "Fuel" section
(Y page 372). Refuelling

The fuel filler flap is unlocked or locked auto-
matically when you open or close the vehicle
with the key or using KEYLESS-GO.
The position of the fuel filler cap is displayed
8 in the instrument cluster. The arrow
nextt o the filling pump indicates the side of
the vehicle.
Opening X
Switch off the engine.
X Remove the key from the ignition lock.
X KEYLESS-GO: open the driver's door.
This corresponds to key position 0: "key
removed".
The driver's door can be closed again.
X Press the fuel filler flap in the direction of
arrow :.
The fuel filler flap opens slightly.
X Open the fuel filler flap fully.
X Turn the fuel filler flap anti-clockwise and
remove it.
X Insert the fuel filler cap into the holder

RefuellingDriving and parking

X
Completely insert the fille rneck of the fuel
pump nozzle into the tank and refuel.
X Only fill the tank until the pump nozzle
switches off.
i Do not add any more fuel after the pump
stops filling for the first time. Otherwise,
fuel may leak out.
Closing X
Replace the cap on the filler necka nd turn
clockwise until it engages audibly.
X Close the fuel fille rflap.
i Close the fuel filler flap before locking the
vehicle. Otherwise, the locking pin of the
central locking prevents the fuel filler flap
fro mc losing. Refuelling

You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towin
gvehicle in the "Tech-
nical data" section (Y page 381).
When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
to 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 circle
This could impair the handling characteris-
tics. Adapt your style of driving accordingly.
Maintain a safe distance. Drive carefully.
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. Notes on towing
atrailer
General notes !
Use a drawbar noseweigh tas close as
possible to the maximum permissible nose-
weight. Do not use a noseweight of less
than 50kg, otherwise the trailer may come
loose.
Note that the payload and the rear axle load
are reduced by the actual payload.
i When towing a trailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for a maximum load; see the tyre pressure
table in the fuel filler flap (Y page 343).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 380).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg. Missing values for the
E500 BlueEFFICIENCY
model were not available at the time of going
to print. However, the actual noseweight
must not exceed the value give nonthe trailer
tow hitch and trailer identification plates. The
lowest weight applies.
Please note that when towing a trailer, PARK-
TRONIC (Y page 200) and Parking Guidance
(Y page 203) are only available with limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable draw-
bar.
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 68).
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 max-
imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Ben zvehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. Refer to the "Technical
data" section to find out whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing a trailer,
the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for
reasons concerning the operating permit.
This also applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
to when driving without a trailer and it will
consume more fuel.
Change into a lower gear in good time on long
and steep downhill gradients. Towing

Jump-starting
G
WARNING
There is a risk of acid burns when jump-starting a vehicle due to the gases which escape from
the battery. Do not lean over the battery while the engine is being jump-started. G
WARNING
Gases escaping from the battery during jump-starting may cause minor explosions. Avoid cre-
ating sparks. Keep naked flames away from the battery, and do not smoke.
Comply with the important safety precautions when handling batteries. You will find these under
"Battery (vehicle) -important safety notes" in the index. G
WARNING
Non-combusted fuel can collect in the exhaust system and ignite. There is a risk of fire. Avoid
repeated and lengthy starting attempts.
! Vehicles with apetrol engine: avoid repeated and lengthy starting attempts. Otherwise,
the non-combusted fuel may damage the catalytic converter.
Do not use a rapid charging device to start th evehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jump
leads. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's batter yis not accessible,
jump-start the vehicle using a second battery or ajump-starting device.
R vehicles with apetrol engine: only jump-star tthe vehicle when the engine and exhaust
system are cold.
R do not start the engine if the battery is frozen. Let the battery thaw first.
R jump-starting may only be performed from batteries with a nominal voltage of 12 V.
R only use jump leads that have a sufficient cross-section and insulated terminal clamps.
R if the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a little.
R make sure that the two vehicles do not touch.
Make sure that:
R The jump leads are not damaged.
R Non-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
R the jump leads cannot come into contact with parts such as the V-belt pulley or the fan.
These parts move when the engine is started and while it is running.
X Firmly depress the parking brake.
X Manual transmission: engage neutral.
X Automatic transmission: move the selector lever toP.
X Switch off all electrical consumers (e.g. radio, blower, etc.).
X Open the bonnet (Y page 307). Jump-starting
