2011 SMART FORTWO COUPE fuel pump

Freeze warning (Canada vehicles only)
When the outside temperature falls below
3 ¥ , the multifunction display makes you
aware of the fact that the road may be icy.
An additional freeze warning, i.e. an ice
crystal symbol, in the multifunction
display flashes. After 60 seconds, the
freeze warning stops flashing but
continues to be displayed. When the
outside temperature rises above 3 ¥, the
freeze warning goes out.
Fuel level display
Example illustration (U.S. vehicles)
The fuel level display shows the tank’s fuel
level with the aid of eight segments. The
number of dark segments indicates the fuel
level in the tank. If all eight segments are
dark, the tank is full.
You are driving on reserve fuel if there are
no more than 1.0 US gal (3.78 l) of fuel in the
tank.
If this occurs,
R the fuel pump symbol in the fuel level
display flashes
R the reserve fuel indicator shows the fuel
level in the tank in 0.1 US gal (0.5 l)
increments
For selecting the reserve fuel indicator to
be displayed in the status indicator, see
“Reserve fuel indicator” ( Y page 92).

The fuel filler cap is tethered to the
fuel filler flap. Do not drop the fuel
filler cap. It could damage the vehicle
paint finish.

the fuel filler flap.XFully insert filler nozzle unit and
refuel.XOnly fill your tank until the filler nozzle
unit cuts out — do not top off or overfill .GWarning!
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel pump
nozzle, which could cause personal injury.
XReplace fuel filler cap 008A.XTurn fuel filler cap 008A clockwise until
the handle grip overturns.
i Make sure to close the fuel filler flap
before locking the vehicle as the fuel
filler flap locking pin prevents closing
after you have locked the vehicle.
XClose the fuel filler flap.
You should hear the latch close shut.
i 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.
Please contact gas station personnel in
case labels on the pump cannot be found.

Open the engine compartment cover to
check the engine oil level and if necessary,
to add engine oil.
GWarning!
High outside temperature, stop-and-go
traffic, driving on long uphill grades or
driving at high engine speed may increase
the temperature in the engine
compartment. Therefore, the engine
compartment cover and parts in the area
around the engine compartment cover may
be hot. Parts of the engine can become very
hot. To prevent burns, let the engine cool
off completely before touching the engine
compartment cover, parts in the area
around the engine compartment cover, and
parts of the engine.

Driving when your engine is overheated can cause some fluids which may have leaked into
the engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle until the engine has cooled down.
! Among other possible causes, the poly-V-belt could be broken. Do not continue to
drive. Otherwise, the engine will overheat due to an inoperative water pump which may
result in damage to the engine.

XAfter driving for about 1.8 miles (3 km)
or ten minutes, take all of the
appropriate safety precautions and then
take the tire repair kit from the vehicle.XScrew the end of filler hose 0088 onto tire
valve 0072.XCheck the tire inflation pressure using
pressure gauge 0047.GWarning!
If tire inflation pressure has fallen below
130 kpa (1.3 bar, 20 psi) do not continue to
drive the vehicle.
Park your vehicle safely away from the
roadway and contact the nearest smart
center or call Roadside Assistance.
Have the damaged tire replaced.
XIf the tire inflation pressure is at least
130 kpa (1.3 bar, 20 psi), inflate or deflate
the tire to correct tire inflation
pressure (see Tire and Loading
Information placard located on the
driver’s door B‑pillar).
R To increase the tire inflation
pressure: Switch on the electric air
pump.
R To decrease the tire inflation
pressure: Open vent screw 008A. Recheck
the tire inflation pressure with the
electric air pump’s pressure gauge.XAfter checking the tire inflation
pressure, unscrew the end of filler
hose 0088 from tire valve 0072.XPlug filler hose with the stopper.XPlace the tire repair kit securely in the
vehicle.XScrew the valve cap onto the tire valve.
! The manufacturer is unable to
guarantee that all tire punctures can be
repaired with the tire repair kit, in
particular cuts or perforations larger
than approximately 0.16 in (4 mm) or away
from the tire’s tread. The manufacturer
is not liable for damage sustained
through improper use of the tire repair
kit.GWarning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel
economy, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
XDrive to the nearest authorized smart
center, to have the damaged tire
replaced.XContact an authorized smart center as
soon as possible to obtain a new filler
hose and a new tire sealant container.XBring used tire sealant materials to an
authorized smart center for proper
disposal.XReplace your tire sealant container
every 4 years. Replacement containers
are available at any authorized smart
center.GWarning!
After changing a tire, contact a smart
center to make sure the bolts holding the
wheel to the car are tight enough.
Otherwise, the wheels could come off. Each

Fuel requirements
Only use premium unleaded fuel. The octane
number (posted at the pump) must be 91 min.
It is an average of both the Research Octane
N umber (RON) and the Motor Octane Number
(MON): (RON+MON)/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.
Gasoline additives
A major concern among engine
manufacturers is carbon build-up caused
by gasoline. smart recommends only the use
of quality gasoline containing additives
that prevent the build-up of carbon
deposits.
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:
R Warm-up hesitation
R Unstable idle
R Knocking/pinging
R Misfire
R Power loss
In areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
the use of smart approved additives is
recommended. Contact an authorized smart
center for a listing of approved products.
Follow directions on the 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
additional fuel additives other than
those tested and approved by us for use
on smart vehicles are not covered by the
smart Limited Warranty.
