When the message At next gas station
add 1.0 qt engine oil

(Canada:
1.0 liter) appears while the
engine is running and at operating
temperature, the engine oil level has
dropped to approximately the minimum
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 oil leaks
are noted, continue to drive to the nearest
service station where the engine oil should
be topped to the required level with an
approved engine oil. For information on
approved engine oils, refer to the Factory
Approved Service Products pamphlet
(USA only) or contact an authorized
Mercedes-Benz Light Truck Center.

428 Technical data
Fuels, coolants, lubricants, etc.
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase boil-over protec-
tion. 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-Bent approved
products of equal specification are used to
renew the coolant concentration or bring it
back up to the proper level.
For information on other Mercedes-Benz
approved products of equal specification,
refer to the Factory Approved Service
Products pamphlet (USA only) or contact
an authorized Mercedes-Benz Light Truck
Center.To provide important corrosion protection,
the solution must be at least
50% anticorrosion/antifreeze (equivalent
to freeze protection to approximately
-35°F [-37°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 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,
contact an authorized Mercedes-Benz
Light Truck Center.Anticorrosion/antifreeze
Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be
specifically formulated to protect the
aluminum parts. Failure to use such
anticorrosion/antifreeze coolant will
result in a significantly shortened service
life.
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz
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 an authorized Mercedes-Benz
Light Truck Center for service.
