Press combination switch briefly in di-
rection of arrow1.
The windshield wipers wipe one time 
without washer fluid.
Wiping with windshield washer fluid
Push combination switch in direction of 
arrow2 past the resistance point.
The windshield wipers operate with 
washer fluid.
For information on filling up the washer 
reservoir, see “Windshield washer sys-
tem and headlamp cleaning system*” 
(page 295).
!The switch should not be left in inter-
mittent setting as the wipers will wipe 
the windshield once every time the en-
gine is started. Dust that accumulates 
on the windshield might scratch the 
glass and/or damage the wiper blades 
when wiping occurs on a dry wind-
shield.
Vehicles with rain sensor*:
Do not leave windshield wipers in inter-
mittent setting when vehicle is taken to 
an automatic car wash or during wind-
shield cleaning. Wipers will operate in 
the presence of water sprayed on the 
windshield, and wipers may be dam-
aged as a result.
iIntermittent wiping is interrupted when 
the vehicle is at a standstill and a door 
is opened.
Intermittent wiping will be continued 
when
all doors are closed
the clutch pedal is depressed (vehi-
cles with manual transmission)
the gear selector lever is in 
positionDorR (vehicles with auto-
matic transmission*)

293 Operation
Engine compartment
Transmission fluid level*
Vehicles with automatic transmission*: 
The transmission fluid level does not need 
to be checked. If you notice transmission 
fluid loss or gear shifting malfunctions, 
have an authorized Mercedes-Benz Center 
check the transmission.
Coolant level
The engine coolant is a mixture of water 
and anticorrosion/antifreeze. To check 
the coolant level, the vehicle must be 
parked on level ground and the engine 
must be cool.Warning!
G
In order to avoid any 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 indi-
cates that the coolant is overheated.
Do not remove pressure cap on coolant 
reservoir if coolant temperature is 
above 158°F (70°C). Allow engine to 
cool down before removing cap. The 
coolant reservoir contains hot fluid and 
is under pressure.
Using a rag, slowly open the cap approx-
imately ½ turn to relieve excess pres-
sure. If opened immediately, scalding 
hot fluid and steam will be blown out un-
der 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.
