Introduction

• SPARK PLUGS

Spark plugs should be replaced according
to the specified maintenance interval.
Severe operating conditions (frequent
starting and stopping, excessive idling,
sustained fast highway driving) may
call for spark plugs to be replaced
correspondingly sooner.

• COOLANT

Coolant should be checked for the
proper concentration before the start
of the winter season (or once a year in
hot regions). Have the coolant (water/
anticorrosion/antifreeze mixture)
replaced at the specified maintenance
interval for your vehicle model.
In vehicles with engine 275, the coolant
for the main circuit should be checked for
proper concentration before the start of
each winter season (or once a year in hot
regions) and replaced every 3 years. The
coolant for the low temperature circuit
should be replaced every 240,000 KM or
15 years.
Replacement of coolant may be required
more frequently if coolant is not
maintained according to instructions and/
or other than approved anticorrosion/
antifreeze products for your vehicle are
being used. For instructions on coolant,
see "Coolants" in your vehicle Operator's
Manual. For a listing of approved
anticorrosion/antifreeze products for
your vehicle, contact your authorized
Mercedes-Benz Dealer.
G
Warning!
Please make sure you read the technical documentation, such as the Operator's Manual and
workshop information, before carrying out any maintenance work.

• BRAKE FLUID

Brake fluid should be replaced every
two years, preferably in the spring. We
recommend that you only use brake
fluid approved by Mercedes-Benz. A
reminder for the next scheduled brake
fluid replacement is affixed in the engine
compartment.

Wear items

While the Mercedes-Benz Maintenance
System calls for inspection of certain
wear items, the system does not make
any judgment on the condition of these
wear items. Only a qualified technician
can determine if a wear item needs to be
replaced.
