A
Reserve fuel
The fuel level has dropped below the re-
serve mark.

Refuel at the next gas station
(page 290).
Check gas cap
See Operator’s Manual
A loss of pressure has been detected in
the fuel system. The fuel cap may not be
closed properly or the fuel system may be
leaky.

Check the fuel cap (
page 290).
If it is not closed properly:

Close the fuel cap.
If it is closed properly:

Have the fuel system checked by an
authorized Mercedes-Benz Center.

423 Practical hints
Flat tire

Visit an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT kit.

Bring used TIREFIT materials to an
authorized Mercedes-Benz Center for
proper disposal.

Replace your TIREFIT container every
4 years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Mounting the spare wheel
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
Do not exceed vehicle speed of 50 mph
(80 km/h). A TIREFIT repair is not designed
to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.
Warning!
G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
from those of the road wheels. As a result,
the vehicle handling characteristics change
when driving with a spare wheel mounted.
Adapt your driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare or collapsible tire is mounted.

428 Practical hintsFlat tire
Screw union nut5 onto the tire valve.

Insert electrical plug3 into vehicle
cigarette lighter socket (
page 258).

Turn the SmartKey in the starter switch
to position1.
or

Press the KEYLESS-GO* start/stop
button on the gear selector lever once
without depressing the brake pedal.

Press I on electric air pump switch2.
The electric air pump should now
switch on and inflate the tire.

Inflate the tire to approximately 51 psi
(3.5 bar).
This takes about 5 minutes for the col-
lapsible tire. Air hose4 and union
nut5 can become hot during infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.

Press 0 on electric air pump switch2.

Turn the SmartKey in the starter switch
to position0.
or

Press KEYLESS-GO* start/stop button
on the gear selector lever twice without
depressing the brake pedal.
The electric air pump should now be
switched off.

If the tire inflation pressure is above
51 psi (3.5 bar), release excess tire in-
flation pressure using the vent screw.

Detach the electric air pump.

Stow electrical plug3 and air hose4
behind flap1 and place the air pump
back in the trunk.
!Do not operate the air pump longer
than 8 minutes without interruption.
Otherwise it may overheat.
You may operate the air pump again
after it has cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes, etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.


450 Technical dataRims and tires
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar. Some vehicles may have sup-
plemental tire inflation pressure infor-
mation for driving at high speeds
(page 312) or for vehicle loads less
than the maximum loaded vehicle con-
dition. If such information is provided,
it can be found on the placard located
on the inside of the fuel filler flap. The
tire inflation pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire
manufacturer’s maintenance recom-
mendation included with vehicle.
iThe following pages also list the ap-
proved wheel rim and tire sizes for
equipping your vehicles with winter
tires. Winter tires are not available as
standard or optional factory equip-
ment, but can be purchased from an
authorized Mercedes-Benz Center.
Depending on vehicle model and the
standard or optional factory-equipped
wheel rim/tire configuration on your
vehicle (Appearance Package, Sport
Package etc.), equipping your vehicle
with winter tires approved for your ve-
hicle model may also require the pur-
chase of two or four wheel rims of the
recommended size for use with these
winter tires. See an authorized
Mercedes-Benz Center for more infor-
mation.

466 Technical dataFuels, coolants, lubricants etc.In areas where carbon deposits may be
encountered due to lack of availability of
gasolines 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
Only use premium unleaded gasoline
meeting ASTM standard D 439.
The octane number (posted at the pump)
m u s t b e 9 1 m i n . I t i s a n a v e r a g e o f b o t h t h e
Research (R) Octane Number and the Mo-
tor (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.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-
vides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
