ignition system


exhaust system


fuel system

Have the measuring system checked
by an authorized Mercedes-Benz
Center.
B
Coolant
Check level
The coolant level is too low.

Add coolant (
page 321).

If you have to add coolant frequently,
have the cooling system checked by
an authorized Mercedes-Benz Center.
Warning!
G
Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. You can be seriously burned.
!Do not ignore the low engine coolant
level warning. Extended driving with
the message and symbol displayed
may cause serious engine damage not
covered by the Mercedes-Benz Limited
Warranty.
Do not drive without sufficient amount
of coolant in the cooling system. The
engine will overheat causing major en-
gine damage.

Coolant
Stop, engine off
The poly-V-belt could be broken.

Stop the vehicle in a safe location as soon as it is
safe to do so and immediately turn off the engine.

Check the poly-V-belt.
If it is 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. Notify
an authorized Mercedes-Benz Center.
If it is intact:

Do not continue to drive the vehicle with this mes-
sage displayed. Doing so could result in serious
engine damage that is not covered by the
Mercedes-Benz Warranty.

Drive immediately to the nearest authorized Mer-
cedes-Benz Center.

Possible cause/consequence
Possible solution
:

There is no oil in the engine. There is a
danger of engine damage.

Carefully bring the vehicle to a halt as
soon as possible.

(
page 317).
Engine oil level
Visit workshop
E 500, E 55 AMG only:
The engine oil has dropped to a critical
level.

Check the engine oil level
(page 317) and add oil as required
(page 319).

If you must add engine oil frequently,
have the engine checked for possible
leaks.
Change engine oil
Visit workshop
E 500, E 55 AMG only:
It may be that there is water in the engine
oil.

Have the engine oil and the cooling
system checked.

Have oil siphoned or drained off. Ob-
serve all legal requirements with re-
spect to its disposal.
Oil sensor malfunction

In areas where carbon deposits may be en-
countered 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
Use only premium unleaded gasoline
meeting ASTM standard D 439:

The octane number (posted at the
p um p) mu st b e 9 1 m i n. It is a n ave ra ge
of both the Research (R) Octane Num-
ber and the Motor (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.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over pro-
tection. Refer to Maintenance Booklet for
replacement interval.

488 Technical dataFuels, coolants, lubricants etc.Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration or bring it back up to the proper
level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze [equivalent to freeze
protection to approximately - 22°F
(-30°C)]. If you use a solution that is more
than 55% anticorrosion/antifreeze [freeze
protection to approximately - 49°F
(-45°C)], the engine temperature will in-
crease due to the lower heat transfer capa-
bility of the solution. Therefore, do not use
more than this amount of anticorro-
sion/antifreeze.If the coolant level is low, water and MB
325.0 anticorrosion/antifreeze should be
used to bring it up to the proper level (have
cooling system checked for signs of leak-
age). Please make sure the mixture is in
accordance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum
parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life).Therefore, the following product is strongly
recommended for use in your vehicle:
MB 325.0 anticorrosion/antifreeze agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to your authorized Mercedes-Benz
Center for service.
