add 1.0 l engine oil
The engine oil level is too low.

Add engine oil (
page 274) and check
the engine oil level (
page 272).
Engine oil level
Stop, engine off!
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.

Turn off the engine.

Add engine oil (
page 274) and check
the engine oil level (
page 272).
Engine oil level
Reduce oil level
You have added too much engine oil.
There is a risk of damaging the engine or
the catalytic converter.

Have oil siphoned or drained off.
Observe all legal requirements with
respect to its disposal.
Change engine oil
Visit workshop.
It may be that there is water in the engine
oil.

Have the engine oil checked.

313 Practical hints
What to do if …
When the message
At next gas station
add 1.0 qt engine oil
(Canada:
1.0 l
)
appears while the engine is running and at
operating temperature, the engine oil level
has dropped to approximately the mini-
mum level.When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.
Visually check for oil leaks. If no obvious oil
leaks are noted, drive to the nearest
service station where the engine oil should
be topped to the required level with an
approved oil specified in the Factory
Approved Service Products pamphlet.

Suggested solution
:
Engine oil level
Visit workshop.
The engine oil has dropped to a critical
level.

Check the engine oil level
(page 272) and add oil as required
(page 274).

If you must add engine oil frequently,
have the engine checked for possible
leaks.
Oil sensor malfunction
Visit workshop.
The measuring system is malfunctioning.

Have the measuring system checked
by an authorized Mercedes-Benz
Center.!The engine oil level warnings should
not be ignored. Extended driving with
the symbol displayed could result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.

Belt system
Drive to workshop
The seat belt system is malfunctioning.

Visit an authorized Mercedes-Benz
Center as soon as possible.
_
Steering oil
Visit workshop.
The steering gear oil level is too low.
There is a danger of steering gear
damage.

Have the system checked by an
authorized Mercedes-Benz Center.
Warning!
G
If the level of steering gear oil in reservoir is
too low, the steering power assistance could
fail. Much greater effort will then be needed
to turn the steering wheel.
Do not add steering oil without checking the
steering system.
Do not drive the vehicle. Have the system
checked at an authorized Mercedes-Benz
Center as soon as possible.

379 Technical data
Fuels, coolants, lubricants, etc.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which
provides:

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
corrosion protection.
If the antifreeze mixture is effective
to -22°F (-30°C), the boiling point of the
coolant in the pressurized cooling system
is reached at approx. 266°F (130°C).The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over
protection. Refer to Maintenance Booklet
for replacement interval.
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
solution or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products
pamphlet) are used to renew the coolant
concentration or bring it back up to the
proper level.
To provide important corrosion protection,
the solution must be at least 45%
anticorrosion/antifreeze [equivalent to
freeze protection to approx. - 22°F
(-30°C)]. If you use a solution that is more than 55%
anticorrosion/antifreeze [freeze
protection to approx. - 49°F (-45°C)], the
engine temperature will increase due to
the lower heat transfer capability of the
solution. Therefore, do not use more than
this amount of anticorrosion/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
leakage). 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,
consult an authorized Mercedes-Benz
Center.

System)
Information and operating center for
vehicle sound and communications
systems, including the radio and the
navigation system, as well as other
optional equipment (CD changer*,
telephone*, etc.).
Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to
adjust settings.
Cruise control
Driving convenience system that
automatically maintains the vehicle
speed set by the driver.Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine
produced.
Engine oil viscosity
Measurement for the inner friction
(viscosity) of the oil at different temper-
atures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can
tolerate without becoming viscous, the
better the viscosity.
ESP

the automatic transmission for shifting.
The automatic gear shifting process
can be adapted to specific operating
conditions using the gear selector
lever.
