When this message appears while the engine is
running, the level of the reservoir has dropped to
approximately
1/3 of the total volume. The reservoir
should be refilled with the prescribed mixture of MB
Windshield washer concentrate and water or the
concentrate and commercially available premixed
windshield washer solvent / antifreeze, depending on
ambient temperature, at the next opportunity. The
reservoir for the windshield and headlamp washer
systems is located in the engine compartment.
See windshield and headlamp washer system on

Adding coolant
If coolant has to be added, a 50/50 mixture of water and
MB anticorrosion / antifreeze should be added.Windshield and headlamp washer system
1Windshield and headlamp washer fluid reservoir
The reservoir should be refilled with MB Windshield
Washer Concentrate and water (or concentrate
commercially available premixed windshield washer
solvent / antifreeze, depending on ambient
temperatures).
Wa r n i n g !
• In order to avoid possibly serious burns:
Use extreme caution when opening the hood if
there are any signs of steam or coolant leaking
from the cooling system, or if the coolant
temperature gauge indicates that the coolant is
overheated.• Do not remove pressure cap on coolant
reservoir if engine temperature is above 194
°F
(90
°C). Allow engine to cool down before
removing cap. The coolant reservoir contains
hot fluid and is under pressure.
• Using a rag, slowly open cap approximately
1/2 turn to relieve excess pressure. If opened
immediately, scalding hot fluid and steam will
be blown out under pressure.• Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may
burn if it comes into contact with hot engine
parts.

Headlamp adjustment
Correct headlamp adjustment is extremely important.
Check and readjust headlamps at regular intervals and
when a bulb has been replaced.Replacing bulbs
Notes:
To prevent a possible electrical short circuit, switch off
lamp prior to replacing a bulb.
When replacing bulbs, install only 12 volt bulbs with
the specified watt rating.
When replacing halogen bulbs do not touch glass
portion of bulb with bare hands. Use plain paper or a
clean cloth.
If the newly installed bulb does not light up, switch the
lamp off and on again. If the bulb still does not light up,
have the system checked at an authorized
Mercedes-Benz Center.
Wa r n i n g !
Bulbs and bulb holders can be very hot. Allow the
lamp to cool down before changing a bulb.
Halogen lamps contain pressurized gas. A bulb can
explode if you:
• touch or move it when hot,
•drop the bulb,
• scratch the bulb.Wear eye and hand protection.
Wa r n i n g !
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.
