and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
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 medical assistance with-
out delay. R
If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing. R

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.
Do not get into the vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
! 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. 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 sys-
tem could be blocked by particles from the
fuel can. If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.

Do not mix such fuels with the fuel recom-
mended for your vehicle.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of a lower grade, observe the following pre-
cautions: R
Only fill the fuel tank to half full with regular
unleaded gasoline and fill the rest with pre-
mium-grade unleaded gasoline as soon as
possible. R
Do not drive at the maximum speed. R
Avoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the pump. If you cannot find the label
on the pump, ask the staff for assistance.
i For further information, consult a qualified
specialist workshop or visit
http://www.mbusa.com (USA only).
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid
driving at full throttle and sudden acceleration.
Never refuel using fuel with a lower AKI.
Information on refueling .
Additives
! Operating the engine with fuel additives
added later can lead to engine failure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Comply with the instructions
for use on the product label. More information
about recommended additives can be
obtained from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use bran-
ded fuels that have additives. The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the injection system as a result. In such
cases, and in consultation with an authorized
Mercedes-Benz Center, the gasoline may be
mixed with the cleaning additive recommended
by Mercedes-Benz. You must observe the notes
and mixing ratios specified on the container.
Engine oil
General notes
! Never use engine oil or an oil filter of a spec-
ification other than is necessary to fulfill the
prescribed service intervals. Do not change
the engine oil or oil filter in order to achieve
longer replacement intervals than those pre-
scribed. You could otherwise cause engine
damage or damage to the exhaust gas after-
treatment.
Follow the instructions in the service interval
display regarding the oil change. Otherwise,
you may damage the engine and the exhaust
gas aftertreatment.
When handling engine oil, observe the important
safety notes on service products ( Y
page 427).
The engine oils are matched to the performance
of Mercedes-Benz engines and service intervals.
You should therefore only use engine oils and oil
filters that are approved for vehicles with main-
tenance systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center.
