Resetting the maintenance service
indicator
In the event that the maintenance service on
your vehicle is not carried out at an authorized
Mercedes-Benz Center, you can have the
maintenance service indicator reset.
The automotive maintenance facility carrying
out the maintenance service will find the
information for resetting the maintenance
service indicator in the maintenance-relevant
literature for your vehicle.
Such literature is available at any authorized
Mercedes-Benz Center or directly from
Mercedes-Benz.
! If the maintenance service indicator was
reset inadvertently, have an authorized
Mercedes-Benz Center correct it.
Only reset the maintenance service
indicator if the proper maintenance service
has been performed. Not following the
proper maintenance service as described
in the Maintenance Booklet will result in
engine damage and/or other vehicle
damage not covered by the Mercedes-Benz
Limited Warranty.
Vehicle care
Cleaning and care of the vehicle
Notes
Regular and proper care will help to maintain
the value of your vehicle.
GWarning!
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your
vehicle’s doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and keep
them out of reach of children.
! When cleaning the vehicle, do not use
scouring agents. Never apply strong force
and only use a soft, wet cloth or sponge.
Otherwise you may scratch or damage the
surface to be cleaned.
While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the vehicle
underbody and cause lasting damage.
Such damage is caused not only by extreme
and varying climatic conditions, but also by:
R Air pollution
R Road salt
R Tar
R Gravel and stone chipping
To avoid paint damage, you should
immediately remove:
R Grease and oil
R Fuel
R Coolant
R Brake fluid
R Bird droppings
R Insects
R Tree resins etc.
Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above
adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:
R near the ocean
R in industrial areas (smoke, exhaust
emissions)
R during winter operation
You should check your vehicle from time to
time for stone chipping or other damage. Any
damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody of
the vehicle. A prerequisite for a thorough
check is a washing of the underbody followed
by a thorough inspection. Damaged areas
need to be re-undercoated.354Vehicle careOperation

The message will be stored in the vehicle status message memory after you have cleared it
from the multifunction display.
Visually check for oil leaks. If there are no obvious oil leaks, drive to the nearest service station
to refill your engine oil to the required level.

the respective bulb checked and replaced if
necessary.
When you switch on the ignition, all lamps in
the instrument cluster come on. The low-

GWarning!
Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.
! The engine should not be operated with the engine oil temperature above 140†. Doing
so may cause serious damage which is not covered by the Mercedes-Benz Limited Warranty.

use of Mercedes-Benz approved additives is
recommended.
Contact an authorized Mercedes-Benz Center
or visit http://www.MBUSA.com (USA
only) for a listing of approved products.
Follow directions on the product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and may
be harmful to the engine operation.
! Damage or malfunction resulting from
poor fuel quality or from blending additional
fuel additives other than those tested and
approved by us for use on Mercedes-Benz
vehicles are not covered by the Mercedes-
Benz Limited Warranty or by any pre-owned
or Extended Limited Warranties.
Coolants
The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the boiling
point)
The cooling system was filled at the factory
with a coolant providing freeze protection to
approximately -35‡ (-37†) and corrosion
protection.
! Add premixed coolant solution only.
Adding water and MB 325.0 Anticorrosion/
Antifreeze separately from each other,
could cause engine damage not covered by
the Mercedes-Benz Limited Warranty.
If the antifreeze mixture is effective to -35‡
(-37†) , the boiling point of the coolant in the
pressurized cooling system is reached at
approximately 266‡ (130†).
The coolant solution must be used year round
to provide the necessary corrosion protection
and increase boil-over protection. Refer to
the 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 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,
contact an authorized Mercedes-Benz Center
or visit http://www.MBUSA.com (USA
only).
To provide important corrosion protection,
the solution must be at least 50%
anticorrosion/antifreeze (equivalent to
freeze protection to approximately -35‡
[-37†]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protection
to approximately -49‡ [-45†]), 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
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
