Infrared reflective windshield
The infrared reflecting glass prevents the vehi-
cle interior from becoming too hot. It also blocks
radio waves from penetrating the windshield up
into the gigahertz range.
In order to operate radio-controlled equipment,
e.g. toll recording systems, areas 0043on the
windshield are permeable to radio waves. You
can install radio-controlled devices in these
areas.
These areas can best be seen from outside the
vehicle by observing the light reflected off the
windshield.

Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING
When opening and closing the hood, it may
suddenly fall into the closed position. There is a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one is
within its range of movement.
GWARNING
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.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The ignition system and the fuel injection sys-
tem work under high voltage. If you touch
components which are under voltage, you
could get an electric shock. There is a risk of
injury.
Never touch components of the ignition sys-
tem or fuel injection system when the ignition
is switched on.
Opening the hood
GWARNING
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.
GWARNING
When the hood is open and the windshield
wipers are set in motion, you can be injured by
the wiper linkage. There is a risk of injury.
Always switch off the windshield wipers and
the ignition before opening the hood.
!Make sure that the windshield wipers are
not folded away from the windshield. You
could otherwise damage the windshield wip-
ers or the hood.

opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
General notes
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 l) of oil per
600 miles (1000 km). The oil consumption may
be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in a different location.
When checking the oil level:
Rpark the vehicle on a level surface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rif the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait about 30 minutes before carrying
out the measurement
Checking the oil level using the oil dip-
stick (except Mercedes-AMG S 65)
Example: checking the oil level using the oil
dipstick
XPull oil dipstick0043out of the dipstick guide
tube.
XWipe off oil dipstick 0043.
XSlowly slide oil dipstick 0043into the guide tube
to the stop, and take it out again.
If the level is between MIN mark 0087and MAX
mark 0044, the oil level is correct.
XIf the oil level has dropped to MIN mark 0087or
below, add 1.1 US qt (1.0 l)of engine oil.
Checking the oil level using the on-
board computer (Mercedes-AMG S 65)
Calling up the oil level check
XTurn the SmartKey to position 2in the ignition
lock (Ypage 121).
or
XOn vehicles with KEYLESS-GO, press the
Start/Stop button twice (Ypage 121).
XUse 00E2 on the steering wheel to call up the
list of menus.
XPress the 0064or0063 button on the steering
wheel to select the Servicemenu.
XConfirm by pressing 0076on the steering

Example: checking the coolant level
XPark the vehicle on a level surface.
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the SmartKey to position2in the ignition
lock (Ypage 121).
or
XOn vehicles with KEYLESS-GO, press the
Start/Stop button twice (Ypage 121).
XCheck the coolant temperature display in the
instrument cluster (Ypage 187).
The coolant temperature must be below
158 ‡ (70 †).
XTurn the SmartKey to position 0in the ignition
lock (Ypage 121).
or
XPress the Start/Stop button once on vehicles
with KEYLESS-GO (Ypage 121).
XSlowly turn cap 0043counter-clockwise and to
relieve excess pressure.
XTurn cap 0043further counter-clockwise and
remove it.
If the coolant is at the level of marker bar 0087
in the filler neck when cold, there is enough
coolant in coolant expansion tank 0044.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar 0087in the filler neck
when warm, there is enough coolant in expan-
sion tank 0044.
XIf necessary, add coolant that has been tested
and approved by Mercedes-Benz.
XReplace cap 0043and turn it clockwise as far as
it will go.
For fu rther i
nformation on coolant, see

Adding washer fluid to the windshield
washer system
GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
Example: adding fluid to the windshield
washer system
XTo open: pull cap0043upwards by the tab.
XPlace cap 0043on the edge of the filler neck and
engage in place.
XAdd the premixed washer fluid.
XTo close: press cap 0043onto the filler neck

Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
