G
Warning!
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system. These materials could be
ignited and cause a vehicle fire. Vehicle movement may result in serious
personal injury or damage to the vehicle or
vehicle drivetrain. Therefore, always do the
following before turning off the engine and
leaving the vehicle:
R
Keep right foot on the brake pedal.
R Engage the parking brake.
R Shift the automatic transmission into park
position P.
R Slowly release the brake pedal.
R When

parked on an incline, always turn the
front wheels towards the road curb.
R Turn the SmartKey in the starter switch to
position 0 and remove the SmartKey from
the starter switch, or press the KEYLESS-
GO start/stop button.
R Take the SmartKey with you and lock the
vehicle when leaving. G
Warning!
Vehicles with AIRMATIC:
If you have selected the Comfort suspension
tuning, the vehicle lowers slightly when you
lock

it within approximately 60 seconds after
turning off the engine. You should therefore
make sure that no one is standing near the
wheel arches or lying underneath the vehicle
when it is being locked. Otherwise, personal
injury could result.
Also, make sure your vehicle cannot come
into contact with objects, such as a road curb,
while lowering. Your vehicle could otherwise
be damaged.
Parking brake G
Warning!
Engaging the parking brake while the vehicle
is
in motion can cause the rear wheels to lock
up. You could lose control of the vehicle and
cause an accident. In addition, the vehicle’s
brake lights do not light up when the parking
brake is engaged. 100

G
Warning!
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
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.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†).
! Excessive coolant temperature triggers a
warning in the multifunction display and the
red coolant temperature warning
lamp ? in the instrument cluster comes
on.
The engine should not be operated with a
coolant temperature above 248‡ (120†).
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz
Limited Warranty. Instrument cluster

Mercedes-Benz Center to have the fuel
system drained completely.
! To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel may
reach the catalytic converter, causing it to
overheat and potentially start a fire.
i Only use premium unleaded gasoline with
a minimum Posted Octane Rating of 91
(average of 96 RON/86 MON).
Information on gasoline quality can
normally be found on the fuel pump. Please
contact gas station personnel in case
labels on the pump cannot be found.
For more information on gasoline, see
“Premium unleaded gasoline”
(Y page 299), see “Fuel requirements”
(Y page 299), or contact an authorized
Mercedes-Benz Center, or visit

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

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.

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

G
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
= in coolant expansion tank ;
R for warm coolant: is approximately 0.6 in
(1.5 cm) higher
X Add coolant as required.
X Screw cap : back on and tighten it.
For more information on coolant, see the
“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
