Maintenance and care
!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
Example: cap and coolant expansion tank
Checkingt he coolant level
XStop your vehicle as far awayf rom traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 241).
XSlowly turn cap :half aturn counter-clock-
wise to allow excess pressure to escape.
XTurn cap :further and remove it from cool-
ant expansion tank ;.
XCheck the coolant level.
If the coolant is up to marker bar =in the
filler neck when cold, there is asufficient
amount of coolant in coolant expansion
tank ;.
If the coolant is approximately 0.59 in
(1.5 cm) above marker bar =in the filler neck
when warm, there is asufficient amount of
coolant in coolant expansion tank ;.
Adding coolant
XIf the coolant drops under marker bar =in
the filler neck, add coolant.
Observe the information on the correct cool-
ant mixture ratio and the required water qual-
ity under "Service products and capacities"
(
Ypage 300). To prevent damage to the
engine cooling system, use only approved
corrosion inhibitor/antifreeze that complies
with the Mercedes-Benz Specifications for
Service Products.
XReplace cap :and turn it clockwise to
tighten.
XStart the engine.
XSet the temperature in the vehicle interior to
the maximum output on the air-conditioning
system control panel.
XAfter approximately 5minutes ,switch off the
engine and allow it to cool down.
XCheck the coolant level againa nd add coolant
if necessary.
XClose the hood.
