Hood
G
Warning!
Do not pull the release lever while the vehicle
is in motion. Otherwise the hood could be
forced open by passing air flow.
This could cause the hood to come loose and
injure you and/or others.
Opening G
Warning!
If you see flames or smoke coming from the
engine compartment, or if the coolant
temperature indicator indicates that the
engine is overheated, do not open the hood.
Move away from vehicle and do not open the
hood until the engine has cooled. If necessary,
call the fire department. G
Warning!
You could be injured when the hood is open –
even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns, let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions. G
Warning!
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades. G
Warning!
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnostic
socket) of the ignition system

Closing
G
Warning!
When closing the hood, use extreme caution
not to catch hands or fingers. Be careful that
you do not close the hood on anyone.
Make sure the hood is securely engaged
before driving off. Do not continue driving if
the hood can no longer engage after an
accident, for example. The hood could
otherwise come loose while the vehicle is in
motion and injure you and/or others.
X Let the hood drop from a height of
approximately 8 in (20 cm).
X Check to make sure the hood is fully
closed.
If you can raise the hood at a point above
the headlamps, then it is not properly
closed. Open it again and let it drop with
somewhat greater force. Engine oil
The amount of oil your engine consumes will
depend on a number of factors, including
driving style. Increased oil consumption can
occur when the vehicle is new or the vehicle
is driven frequently at higher engine speeds.
Engine oil consumption checks should only
be made after the vehicle break-in period.
! Do not use any special lubricant additives,
as these may damage the drive assemblies.
Using special additives not approved by
Mercedes-Benz may cause damage not
covered by the Mercedes-Benz Limited
Warranty.
For further information contact an
authorized Mercedes-Benz Center.
Notes on checking engine oil level When checking the oil level
R
the vehicle must be parked on level ground
R with the engine at operating temperature,
the vehicle must have been stationary for at least 5 minutes with the engine turned
off
R with the engine not at operating
temperature, the vehicle must have been
stationary for at least 30 minutes with the
engine turned off
Checking engine oil level X
Open the hood (Y page 178). X
Pull out oil dipstick :.
X Wipe oil dipstick : clean.
X Slowly insert oil dipstick : fully into the
dipstick guide tube.
X Pull out oil dipstick : again after
approximately 3 seconds to obtain
accurate reading.
The oil level is correct when it is between
lower (min) mark = and upper (max)
mark ; of oil dipstick :.
i CLS 550:
The filling quantity between the upper and
lower marks on the oil dipstick is
approximately 2.1 US qt. (2.0 l).
i CLS 63 AMG:
The filling quantity between the upper and
lower marks on the oil dipstick is
approximately 1.6 US qt. (1.5 l).
X If necessary, add engine oil.

Adding engine oil
!
Only use approved engine oils and oil
filters required for vehicles with
Maintenance System. For a listing of
approved engine oils and oil filters, contact
an authorized Mercedes-Benz Center or
visit www.mbusa.com (USA only).
The following will result in engine or
emission control system damage not
covered by the Mercedes-Benz Limited
Warranty:
R Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System.
R Changing of oil and oil filter at change
intervals longer than those called for by
the Maintenance System.
R Using any oil additives. CLS 550 CLS 63 AMG
X
Unscrew filler cap : from filler neck.
X Add engine oil as required. Be careful not
to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
! Excess oil must be siphoned or drained
off. It could cause damage to the engine
and emission control system not covered
by the Mercedes-Benz Limited Warranty.
X Screw filler cap : back on filler neck.
For more information on engine oil, see the
“Technical data” section ( Y page 296) and
(Y page 298). Transmission fluid level
The transmission fluid level does not need to
be checked. If you notice transmission fluid
loss or gearshifting malfunctions, have an
authorized Mercedes-Benz Center check the
transmission. Coolant level
The engine coolant is a mixture of water and
anticorrosion/antifreeze.
When checking the coolant level, the vehicle
must be parked on level ground, and the
coolant temperature must be below 158‡
(70†). 180

Warning!
In order to avoid any potentially serious burns:
R 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 indicator
indicates that the coolant is overheated.
R Do not remove the cap on the coolant
expansion tank if the coolant temperature
is above 158‡ (70†). Allow the engine to
cool down before removing the cap. The
coolant expansion tank contains hot fluid
and is under pressure.
R Using a rag, slowly open the cap
approximately 1
/ 2 turn counterclockwise
to relieve excess pressure. If opened
immediately, scalding hot fluid and steam
will be blown out under pressure.
R Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. X
Using a rag, slowly open cap :
approximately 1
/ 2 turn counterclockwise
to relieve excess pressure.
X Continue turning cap : counterclockwise
and remove it. The coolant level is correct if the level
R
for cold coolant: reaches marking bar

“Technical data” section ( Y page 297) and
(Y page 300). Washer system and headlamp
cleaning system
G
Warning!
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
! Always use washer solvent/antifreeze
where temperatures may fall below
freezing point. Failure to do so could result
in damage to the washer system/fluid
reservoir.
! Only use washer fluid which is suitable for
plastic lenses. Improper washer fluid can
damage the plastic lenses of the
headlamps.
! Do not use distilled or deionized water in
the washer fluid reservoir. Otherwise, the
washer fluid level sensor could be
damaged.
Fluid for the washer system and the headlamp
cleaning system is supplied from the washer
fluid reservoir.
During all seasons, use MB Windshield
Washer Concentrate “MB SummerFit”. Mix it
with water or premixed washer solvent/
antifreeze depending on the ambient
temperature ( Y page 302). Engine compartment

Steam
from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.
