The coolant temperature
gauge showsavalue
above 248 ‡(120 †).
The coolant warning
lamp may also be on and
aw arning tone may
sound.The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 233). Observe the warning notes
as you do so and add coolant if necessary.
If the coolant level is correct,t he engine radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled sufficiently.
XAt coolant temperatures below 248 ‡(120 †), drive to the nearest
qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving in moun-
tainou sterrai nand stop-and-go traffic.

Windshield washer system
GWARNING
Certain components in the engine compart-
ment ,such as the engine, radiator and parts
of the exhaust system, can become very hot.
Workin ginthe engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nentsort he exhaust system. There is arisk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
Example
XTo open: pull cap:upwards by the tab.
XAdd the premixed washer fluid.
XTo close: press cap :ontothe filler neck
until it engages.
If the washer fluid level drops below the recom-
mended minimum fluid level of 1USgal (1 liter),
am essage appears in the multifunction display
promptin gyou to add washer fluid (

Importan tsafety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool dow nbefore yo uadd anti-
freeze .Make sur ethat antifreeze is not spilled
next to the filler neck. Thoroughly clea nthe
antifreeze from components before starting
the engine.
!Only ad dcoolant that has bee npremixed
with the desire dantifreeze protection. You
coul dotherwise damag ethe engine.
Furthe rinformatio noncoolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aqualifie dspecialist workshop.
!Always use asuitabl ecoolant mixture, even
in countries where hig htemperatures prevail.
Otherwise ,the engine cooling system is not
sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products whe nhandling coolant
(
Ypage 284).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection dow nto
-35 ‡(-37 †), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).
