or Canada
If you plan to operate your vehicle in for-
eign countries, please be aware that:

service facilities or replacement parts
may not be readily available,


unleaded gasoline for vehicles with cat-
alytic converters may not be available;
the use of leaded fuels will damage the
catalysts,


gasoline may have a considerably low-
er octane rating, and improper fuel can
cause engine damage.

353 Operation
At the gas station

Open the fuel filler flap completely.

Turn the fuel cap to the left and hold on
to it until possible pressure is released.

Take off the fuel cap.

To prevent fuel vapors from escaping
into open air, fully insert filler nozzle
unit.

Only fill your tank until the filler nozzle
unit cuts out – do not top up or over-
fill.

Replace the fuel cap by turning it
clockwise until it audibly engages.

Close the fuel filler flap.
You should hear the latch close shut.
!
The fuel filler cap is tethered to the fuel filler
neck. Do not drop the cap. It could damage the
vehicle paint finish.
Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gas to spray
back out when removing the fuel pump noz-
zle, which could cause personal injury.
i
Leaving the engine running and the fuel cap
open can cause the yellow fuel tank reserve
warning lamp to flash and the ?malfunction
indicator lamp (USA only) or the± malfunc-
tion indicator lamp (Canada only) comes on.
For more information, see “Practical hints”
(
page 417).
i
Gasoline engine: Only use premium unlead-
ed gasoline with a minimum Posted Octane Rat-
ing of 91 (average of 96 RON/86 MON).
Information on gasoline quality can normally be
found on the fuel pump.
For more information on gasoline, see “Premium
unleaded gasoline (gasoline engine)”
(
page 547), see “Fuel requirements”
(page 548), and the Factory Approved Service
Products pamphlet.
i
Diesel engine: Only use commercially avail-
able vehicular diesel fuels No. 2 or No. 1 (ASTM
D975 No. 2-D or No. 1-D). Information on diesel
quality can normally be found on the fuel pump.
The sulfur content in diesel fuel should not
exceed 50 parts per million (ppm). When using
diesel fuel with a sulfur content of above
300 ppm, the engine oil interval should be
shortened.
For more information on diesel fuels, refer to the
Factory Approved Service Products pamphlet or
contact an authorized Mercedes-Benz Light
Truck Center.

Diesel engine:
The engine is more susceptible to wear and
damage if you use


marine diesel fuel


heating oil

The use of such non-approved fuels and/or
special additives is not covered by the
Mercedes-Benz Limited Warranty.

547 Technical data
Fuels, coolants, lubricants
Premium unleaded gasoline (gasoline engine)
Gasoline additives (gasoline engine)
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the
use of quality gasoline containing additives
that prevent the build-up of carbon depos-
its.
After an extended period of using fuels
without such additives carbon deposits
can build up, especially on the intake
valves and in the combustion area, leading
to engine performance problems such as:

Warm-up hesitation


Unstable idle


Knocking/pinging


Misfire


Power loss
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid in-
haling fumes and skin or clothing contact,
extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors can damage your
health.
!
To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be
used. If premium unleaded is not available and
low octane fuel is used, follow these precau-
tions:


Have the fuel tank only partially filled with
unleaded regular and fill up with premium
unleaded as soon as possible.


Avoid full throttle driving and abrupt acceler-
ation.


Do not exceed an engine speed of 3000 rpm
if the vehicle is loaded with a light load such
as two persons and no luggage.


Do not exceed
2/3 of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain.

548 Technical dataFuels, coolants, lubricantsIn areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Refer to Factory
Approved Service Products pamphlet for a
listing of approved product(s). Follow
directions on product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary costs and
may be harmful to the engine operation.
Damage or malfunction resulting from
poor fuel quality or from blending addition-
al fuel additives other than those tested
and approved by us for use on
Mercedes-Benz vehicles listed in the
Factory Approved Service Products
pamphlet are not covered by the
Mercedes-Benz Limited Warranty.
Fuel requirements
Gasoline engine
Only use premium unleaded fuel.

The octane number (posted at the
pump) must be 91 min. It is an average
of both the Research (R) octane num-
ber and the Motor (M) octane number:
(R+M) /2). This is also known as the
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Diesel engine
Only use commercially available vehicular
diesel fuels No. 2 or No. 1 (ASTM D975 No.
2-D or No. 1-D).
To prevent malfunctions, diesel fuel with
improved cold flow characteristics is of-
fered in the winter months. Check with
your fuel retailer.
!
Do not fill the tank with gasoline. Do not
blend diesel fuel with gasoline or kerosine. The
fuel system and engine will otherwise be dam-
aged, which is not covered by the
Mercedes-Benz Limited Warranty.
