GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not comeinto contact with your skin, eyes or clothing
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 Immediately change out of clothing which
has come into contact with fuel.
!Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the wrong fuel result in damage to the fuel sys-
tem and 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 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.

Wheel and tire combinations
General notes
GWARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-dent.
Always replace wheels and tires with those
that fulfill the specifications of the originalpart.
When replacing wheels, make sure to use the correct:
R designation
R model
When replacing tires, make sure to use the
correct:
R designation
R manufacturer
R model
GWarning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel, or
consult a qualified specialist workshop.
!For safety reasons, Mercedes-Benz rec-
ommends that you only use tires, wheels
and accessories which have been approved by Mercedes-Benz specifically for your
vehicle. These tires have been specially
adapted for use with the driving safety sys-
tems, such as ABS or ESP ®
.
Only use tires, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tire dimen-
sion variations could cause the tires to
come into contact with the bodywork and
axle components. This could result in dam-
age to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those tes- ted and approved.

!To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavaila-
ble and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions: R Only fill the fuel tank to half full with reg-
ular unleaded gasoline and fill the rest
with premium-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 assis-tance.
iFor further information, consult a quali-
fied specialist workshop or visit

iE10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
As a temporary measure, if the recommended fuel is not available, you may also use regularunleaded 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 accel- eration. Never refuel using fuel with a lowerAKI.
Information on refueling ( Ypage 107).
AMG vehicles
!Only refuel using super-grade unleaded
gasoline with at least 98 RON/88 MON
that conforms to European standard
EN 228 or an equivalent specification.
You could otherwise impair engine output
or damage the engine.
!Premium-grade unleaded gasoline with
an octane rating of 95 RON/85 MON may
be used as a temporary measure if the rec- ommended fuel is not available. This may
reduce engine performance and increase
fuel consumption. Do not drive at full throt-
tle.
!Regular unleaded gasoline with an octane
rating of 91 RON/82.5 MON may also be
used as an emergency measure if the rec-
ommended fuel is not available.
Doing so results in noticeably higher fuel
consumption, and the engine power output is noticeably reduced. Avoid driving at full
throttle.
If only regular unleaded gasoline with an
octane rating of 91 RON/82.5 MON or
lower is available, you must have the vehi-
cle adapted to this fuel at a qualified spe-
cialist workshop.
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
prevention of residue buildup. gasoline
must only be mixed with additives recom-
mended by Mercedes-Benz. Comply with
the instructions for use on the product
label. More information about recommen-
ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels that have additives.
The quality of the fuel available in some coun- tries may not be sufficient. Residue could
build up in the fuel 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 addi-
tive recommended by Mercedes-Benz. You
must observe the notes and mixing ratios
specified on the container.
