X Turn the key to position 1 or 2 in the igni-
tion lock.
X Move the è switch to the corresponding
position.
If the rear window wiper is activated, the
è symbol is shown in the status area of
the display.
The Status Overview in the Assist.
menu then also shows the è symbol for
vehicles with steering wheel buttons
(Y page

X To wipe with washer fluid: press the è
switch beyond the current position as far as
it will go to 1 or press and hold 4.
When you release the è switch, the rear
window wiper continues to wipe for about
another five seconds. The rear window
wiper then wipes according to the original
position 2 or 3.
The rear window wiper switches on automati-
cally if you engage reverse gear and the wind-
shield wipers are on.
If the vehicle is stationary and you open the
tailgate or rear-end door, the rear window
wiper will stop automatically. The rear window
wiper will only resume wiping again when the
tailgate and rear-end door are closed and you
pull away again.
The rear window will no longer be wiped prop-
erly if the wiper blade is worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blade can be found under "Replacing wiper blades"
(

Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you
could be trapped by the wiper arm. There is
a risk of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood/tailgate or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield/rear
window, the windshield/rear window may
be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the wiper
rubber.
Wiper blades are wear parts. The windshield
will no longer be wiped properly if the wiper
blades are worn. This may prevent you from
observing the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yel-
low.110

Opening the hood
G
WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department. G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very
hot. Working in the engine compartment
poses a risk of injury.
Where possible, let the engine cool down
and touch only the components described in
the following.
! Make sure that the windshield wipers are
not folded away from the windshield. You
could otherwise damage the windshield wip-
ers or the hood. Observe the safety notes when you open the
hood.
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away
(Y page 138).
X Pull release handle : on the hood.
The hood is released. X
Reach into the gap and push lever ; on the
hood catch to the left.
X Raise the hood and hold it in that position. X
Pull support strut ? out of retainer = and
guide it up in the direction of the arrow.
X Lower the hood in such a way that support
strut ? glides into recess A and the hood
engages.
Closing the hood G
WARNING
Cloths or other flammable materials left in
the engine compartment can ignite if they
come into contact with the exhaust system
or parts of the engine that heat up. There is
a risk of fire. After carrying out maintenance
work, make sure that no extraneous flam-
mable material is left in the engine compart-
ment or on the exhaust system.
! Do not use your hands to push the hood
down. You could damage it otherwise. Engine compartment

Maintenance and care Z

Comply with instructions on the use, storage
and disposal of service products on the
labels of the respective original containers.
Always store service products sealed in their
original containers. Always keep service
products out of the reach of children. G
WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department. G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very
hot. Working in the engine compartment
poses a risk of injury.
Where possible, let the engine cool down
and touch only the components described in
the following.
Coolant contains glycol and is therefore poi-
sonous. Also observe the safety notes under
"Service products and capacities"
(Y page
305). G
WARNING
The cooling system is pressurized, particu-
larly when the motor is warm. If you open
the cap, you could be scalded if hot coolant
sprays out. There is a risk of injury.
Let the engine cool down before you open
the cap. Wear protective gloves and protec-
tive eyewear when opening. Open the cap
slowly to release pressure.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and
the engine has cooled down. The coolant tem-
perature must be below

122 ‡ (50 †). The
coolant temperature gauge must no longer reach the first line after the letter
C on the
scale and/or the bar display.
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified spe-
cialist workshop. G
WARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled next to the filler neck. Thoroughly
clean the antifreeze from components
before starting the engine.
! Take care not to spill any coolant on pain-
ted surfaces. You could otherwise damage
the paintwork. Example: cap and coolant expansion tank
Checking the coolant level
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page
251).
X Allow the engine to cool down.
X Unscrew cap : slowly about half a turn
counter-clockwise and allow excess pres-
sure to escape. 254
