What you should know at the gas station
Fuel supplyOpen flap by pushing near front (arrow). Turn fuel cap
to the left and hold on to it until possible pressure in
tank has been released, then remove cap. Failure to
remove slowly could result in personal injury.
See page 368 for manual release of fuel filler flap.
Fuel
To prevent fuel vapors from escaping into open air, fully
insert filler nozzle unit.
Only fill fuel tank until the filler nozzle unit cuts out
— do not top up or overfill.
Leaving the engine running and the fuel cap open can
cause the “CHECK ENGINE” lamp to illuminate, see
page 296 for notes on the “CHECK ENGINE” lamp.
Wa r n i n g !
Gasoline is highly flammable and poisonous. It
burns violently and can cause serious injury.
Whenever you are around gasoline, avoid inhaling
fumes and skin contact, extinguish all smoking
materials. Never allow sparks, flame or smoking
materials near gasoline!
P88.60-2001-26
Wa r n i n g !
Overfilling of fuel tank may result in creating
pressure in the system which could cause a gas
discharge such as the gas spraying back out upon
removing the filler nozzle which could cause
personal injury.

Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the electronic
key in steering lock to position 2, have it checked and
replaced if necessary.
Emission control
Certain systems of the engine serve to keep the toxic
components of the exhaust gases within permissible
limits required by law.
These systems, of course, will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the engine should,
therefore, be carried out only by authorized Mercedes-
Benz Center qualified technicians. Engine adjustments
should not be altered in any way. Moreover, the
specified service jobs must be carried out regularly
according to Mercedes-Benz servicing requirements.
For details refer to the Service Booklet.On-board diagnostic system
Check engine malfunction indicator lamp
Engine malfunction indicator lamp. If the
“CHECK ENGINE” malfunction indicator
lamp comes on when the engine is running,
it indicates a malfunction of the fuel management
system, emission control system, systems which impact
emissions, or the fuel cap is not closed tight (check the
fuel cap). If the “CHECK ENGINE” lamp is illuminated
continuously and the vehicle is driving normally, you
Wa r n i n g !
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon monoxide,
and inhaling it can cause unconsciousness and
lead to death. Do not run the engine in confined areas (such as a
garage) which are not properly ventilated. If you
think that exhaust gas fumes are entering the
vehicle while driving, have the cause determined
and corrected immediately. If you must drive under
these conditions, drive only with at least one
window fully open.

349 Battery

and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the trunk
under the right-hand wheel well cover panel.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Wa r n i n g !
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.. Follow recommended
inflation pressures.Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc..

Caution!
To maintain the engine’s durability and performance,
premium unleaded gasoline must be used. If premium
unleaded is not available and low octane fuel is used,
follow these precautions:
•have the fuel tank filled only partially with unleaded
regular and fill up with premium unleaded as soon
as possible,
•avoid full throttle driving and abrupt acceleration,
•do not exceed an engine speed of 3000 rpm, if the
vehicle is loaded with a light load such as two
persons and no luggage,
•do not exceed
2/3 of maximum accelerator pedal
position, if the vehicle is fully loaded or operating in
mountainous terrain.Fuel requirements
Use only Premium unleaded meeting ASTM
standard D 439:
The octane number (posted at the pump) must be
91 min. It is an average of both the Research (R) octane
number and the Motor (M) octane number: (R+M) / 2).
This is also known as 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 not to 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..
