GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or cloth-
ing 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:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vom-
iting.
RImmediately change out of clothing
which has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks
and ignite fuel vapors. There is a risk of
fire and explosion.
Always touch the vehicle body before open-
ing 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
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion 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 quali- fied 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 system could be blocked by par-
ticles from the fuel can.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.

ity (

General information
The fuel filler flap is unlocked or locked
automatically when you lock or unlock the
vehicle with the key.
The position of the fuel filler cap is dis-
played 00B6in the instrument cluster. The

XCompletely insert the filler neck of the
fuel pump nozzle into the tank, hook in
place and refuel.
XOnly fill the tank until the pump nozzle
switches off.
iDo not add any more fuel after the pump
stops filling for the first time. Otherwise,
fuel may leak out.
Closing the fuel filler flap
XReplace the cap on the filler neck and turn
clockwise until it engages audibly.
XClose the fuel filler flap.
iClose the fuel filler flap before locking
the vehicle.
iIf you are driving with the fuel filler cap
open, the 00B6reserve fuel warning lamp
flashes. A message appears in the multi-
function display (
Ypage 125).
In addition, the 00B9Check Engine warning
lamp may light up (
Ypage 136).

Gasoline
Fuel grade
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion 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 quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Only refuel using premium-grade unlea-
ded gasoline with at least 91 AKI/95 RON
(91 octane).
!Only use the fuel recommended. Operating
the vehicle with other fuels can lead to
engine failure.
!Do not use the following:
RE85 (gasoline with 85% ethanol)
RE100 (100% ethanol)
RM15 (gasoline with 15% methanol)
RM30 (gasoline with 30% methanol)
RM85 (gasoline with 85% methanol)
RM100 (100% methanol)
RGasoline with metalliferous additives
RDiesel
Do not mix such fuels with the fuel recom-
mended for your vehicle. Do not use addi-
tives. Engine failure may otherwise occur.
This does not include cleaning additives
for the removal and prevention of residue
build-up. Gasoline must only be mixed with
cleaning additives recommended by smart
(see "Additives"). For further information
inquire at any smart center.
!To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used. If standard unleaded gasoline is unavail-
able and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions:
ROnly fill the fuel tank to half full with
regular unleaded gasoline and fill the
rest with premium-grade unleaded gas-
oline as soon as possible.
RDo not drive at the maximum speed.
RAvoid 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 on the Internet
at http://www.smartusa.com (USA only).
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 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 octane rating.
Information on refueling (
Ypage 97).
Additives
!Operating the engine with subsequently
added fuel additives can lead to engine
damage. Do not mix any fuel additives with the fuel. This does not include additives
for the removal and prevention of residue
buildup. Gasoline must only be mixed with
additives recommended by smart. Comply
with the instructions for use on the product
label. For further information on recom-
mended additives, inquire at any smart
center.
smart recommends that you use fuel brands
that have additives.
The quality of the fuel available in some
countries may not be sufficient. Residue
could build up in the injection system as a
result. In this case, in consultation with a
smart center, the gasoline may be mixed with
the cleaning additive recommended by smart.
