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 refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
If you overfill the fuel tank, pressure may build up in the fuel tank. This could cause fuel to
spray out when the fuel pump nozzle is
removed. There is a risk of injury. The fuel
tank is full when the fuel pump nozzle first
switches off. End the refueling process.
For further information on fuel and fuel quality
(Y page 337). Refueling
Vehicles with a fuel filler flap Example: G 550 fuel filler cap
:
To open the fuel filler flap
; Tire pressure table
= Fuel type
? To insert the fuel filler cap
When you open or close the vehicle with the
SmartKey, the fuel filler flap is automatically
unlocked or locked. The position of the fuel filler cap is displayed
8 in the instrument cluster. The arrow
next to the filling pump indicates the side of
the vehicle. The fuel filler flap is located to the
rear on the right.
Opening the fuel filler cap :
To open the fuel filler flap
; Tire pressure table
= Fuel type
? To insert the fuel filler cap
X Switch the engine off.
i When the engine is running and the fuel
filler flap is open, the yellow reserve fuel
warning lamp and the =(USA only)
or ; (Canada only) Check Engine warn-
ing lamp may light up.
Further information about warning and indi-
cator lamps in the instrument cluster can
be found in the Digital Operator's Manual.
X Remove the SmartKey from the ignition
lock.
X Turn the fuel filler cap counterclockwise
and remove it.
X Insert the fuel filler cap into the holder
bracket on the inside of filler flap ?.
Refueling X
Completely insert the filler neck of the fuel
pump nozzle into the tank and refuel.
i Do not add any more fuel after the pump
stops filling for the first time. Otherwise,
fuel may leak out. 148
RefuelingDriving and parking

Closing
X
Replace the fuel filler cap and turn it clock-
wise. The fuel filler cap audibly engages.
X Close the fuel filler flap.
i Close the fuel filler flap before locking the
vehicle. A locking pin otherwise prevents
the fuel filler flap from closing after the
vehicle has been locked. Fuel filler flap emergency release
The emergency release is located in the cargo
compartment, on the right-hand side when
viewed in the direction of travel, behind the
rear panel trim.
i The vehicle body in the emergency
release area has sharp edges. There is a
risk of injury. Avoid contact with the edges on the inside of the vehicle body.
X Open the rear door.
X Remove edge protection :.
X Remove rear panel trim ;. X
Pull emergency release =in the direction

R
the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When towing a trailer, your vehicle's handling
characteristics will be different in comparison with 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 radius
This could impair the handling characteris-
tics.
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.
General notes R
Do not exceed the legally prescribed max-
imum speed for vehicle/trailer combina-
tions 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 suita-
ble for installing detachable trailer cou-
plings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R If you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to the ball coupling. i
When towing a trailer, set the tire pres-
sure on the rear axle of the towing vehicle
for a maximum load; see the tire pressure
table in the fuel filler flap (Y page 310).
You will find installation dimensions and loads
under "Technical data" (Y page 346).
The maximum noseweight of the trailer draw- bar on the ball coupling for up to 3 people is
562 lbs (255 kg). The maximum noseweight
of the trailer drawbar for more than 3 people and the maximum load for the trunk can be
found in the noseweight table (Y page 347).
However, the actual noseweight must not
exceed the value given on the trailer tow hitch or trailer identification plates. The lowest
weight applies.
Please note that when towing a trailer,
PARKTRONIC (Y page 182) and Blind Spot
Assist (Y page 178) are only available with
limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter accord- ing to the load placed on the vehicle. If nec-
essary, use a trailer with a height-adjusta-
ble drawbar.
Driving tips X
On long and steep downhill gradients,
select shift range 1,2or 3(Y page 145) in
good time.
i This also applies if you have activated
cruise control or SPEEDTRONIC.
X If necessary, shift the transfer case to LOW
RANGE (Ypage 186).
This will use the braking effect of the
engine, so that less braking will be required
to maintain the speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking,
depress the brake pedal repeatedly rather
than continuously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check 192
Towing a trailerDriving an
d parking

the trailer's documents to see what the max-
imum permissible speed is. Observe the
legally prescribed maximum speed in the rel-evant country.
For certain Mercedes-Benz vehicles, 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 utilize any of the added maximum rear axle load when towing a trailer,the vehicle/trailer combination may not
exceed a maximum speed of 60 mph
(100 km/h) for reasons concerning the oper-ating permit. This also applies in countries in
which the permissible maximum speed for
vehicle/trailer combinations is above 60 mph
(100 km/h).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer and it will
consume more fuel.
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
i This also applies if you have activated
cruise control or DISTRONIC PLUS.
This will use the braking effect of the engine,
so that less braking will be required to main-
tain the speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you
need additional braking, depress the brake
pedal repeatedly rather than continuously.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. R
Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude. Trailer power supply
! You can connect accessories with a max-
imum power consumption of 180 W to the
permanent power supply.
You must not charge a trailer battery using the power supply.
The trailer socket of your vehicle is equipped at the factory with a permanent power supply.
The permanent power supply is supplied via
trailer socket pin 9.
A qualified specialist workshop can provide
more information about installing the trailer
electrics. Trailer with 7-pin connector
General notes You can make a connection to the 13-pin
socket on the ball coupling using an adapter
or, if necessary, an adapter cable. Both can be obtained in a qualified specialist workshop.
Installing the adapter !
Make sure that there is enough slack in
the cable for cornering so that the cable
cannot become detached. Towing a trailer
