Operator’s Manual
Operating your vehicle outside the USA 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.Certain Mercedes-Benz models are avail-
able for delivery in Europe under our Euro-
pean Delivery Program. For details, consult

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

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

Close the fuel filler flap.Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas
discharge. This could cause the gasoline to
spray back out when removing the fuel
pump nozzle, which could cause personal in-
jury.
iLeaving the engine running and the fuel
cap open can cause the yellow fuel
tank reserve warning lamp to flash and
theú malfunction indicator lamp
(USA only) or the± malfunction in-
dicator lamp (Canada only) to illumi-
nate.
For more information, see also “Practi-
cal hints” (
page 377).
iGasoline engine:
Only use premium unleaded gasoline
with a minimum Posted Octane Rating
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
the Factory Approved Service Products
pamphlet.
iDiesel engine:
Only use commercially available vehic-
ular 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.
For more information on diesel fuels,
refer to the Factory Approved Service
Products pamphlet. iDiesel engine:
If you have driven the vehicle until the
tank is empty, the fuel system needs to
be bled (
page 449).

488 Technical dataFuels, coolants, lubricants etc.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 en-
gine 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 inju-
ry. Whenever you are around gasoline, avoid
inhaling fumes and skin contact, extinguish
all smoking materials. Never allow sparks,
flame or smoking materials near gasoline!
!To maintain the engine’s durability and
performance, premium unleaded gaso-
line must be used. If premium unleaded
gasoline is not available and low octane
fuel is used, follow these precautions:

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
acceleration


Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded
with a light load such as two per-
sons and no luggage


Do not exceed 2/3 of maximum ac-
celerator pedal position if the vehi-
cle is fully loaded or operating in
mountainous terrain

489 Technical data
Fuels, coolants, lubricants etc.
In areas where carbon deposits may be en-
countered due to lack of availability of gas-
olines 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 di-
rections 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 Fac-
tory Approved Service Products pamphlet
are not covered by the Mercedes-Benz
Limited Warranty.
Fuel requirements
Gasoline engine
Use only premium unleaded gasoline
meeting ASTM standard D 439:

The octane number (posted at the
p um p) mu st b e 9 1 m i n. It is a n ave ra ge
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
better cold flow quality is offered in the
winter months. Check with your fuel
retailer.
!Do not fill the tank with gasoline. Do
not mix diesel fuel with gasoline or
kerosene. The fuel system and engine
will otherwise be damaged, which is
not covered by the Mercedes-Benz
Limited Warranty.

496 Technical termsMaintenance System (U.S. vehicles)
Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. The
Maintenance System in your vehicle
tracks distance driven and the time
elapsed since your last maintenance
service, calculates other maintenance
service work required, and calls for the
next maintenance service accordingly.

The Motor Octane Number for gasoline
as determined by a standardized meth-
od. It is an indication of a gasoline’s
ability to resist undesired detonation
(knocking). The average of both the
MON (Motor Octane Number) and
->RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.
