If you want to interrupt the checking
procedure, press button * or & on
the multifunction steering wheel.
If there is excess engine oil with the engine at
normal operating temperature, the following
message appears in the multifunction
display:
Engine Oil Level
Reduce Oil Level
X Have excess oil siphoned or drained off.
Contact an authorized Mercedes-Benz
Center.
! 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.
For information on messages in the
multifunction display concerning engine oil,
see the “Practical hints” section
(Y page 251).
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. Example illustration: SLK 350 (SLK 300 similar)
SLK 55 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 300) and
(Y page 302). Transmission fluid level
Vehicles with automatic transmission:
The transmission fluid level does not need to
be checked. If you notice transmission fluid
loss or gearshifting malfunctions, have an Engine compartment

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†). 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 display 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. Example illustration: SLK 350
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 301) and
(Y page 304). 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. 196

can lead to a battery explosion and severe
injury or death.
Never
lean over batteries while connecting or
jump starting. You might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery can
result in it exploding, causing personal injury.
Read all instructions before proceeding.
! Vehicles with automatic transmission:
Do not tow-start the vehicle. You could
otherwise seriously damage the automatic
transmission which is not covered by the
Mercedes-Benz Limited Warranty.
! Jump starting should only be performed
using the jump-start terminals located in
the engine compartment.
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick-charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation.
Make sure the cable clamps do not touch
any other metal part while the other end is
still attached to a battery. If the battery is discharged, the engine can be
started with jumper cables and the fully
charged battery of another vehicle or an
equivalent starter pack. Observe the
following:
R
Access
to the battery is not possible on all
vehicles. If you cannot access the battery
of the other vehicle, provide jump start
power by an external battery or starter
pack.
R Jump starting should only be performed
when the engine and catalytic converter
are cold.
R Do not jump start the engine or charge the
battery if the battery is frozen. Let the
battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could damage
the vehicle’s electrical system. Such
damage will not be covered by the
Mercedes-Benz Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained completely,
let the donating power source charge the
vehicle for several minutes before
reattempting the starting process.
The jump-start contacts are located in the
engine compartment on the passenger side.
X Make sure the two vehicles do not touch.
X Switch off all electrical consumers.
X Engage the parking brake.
X Make sure the automatic transmission is in
park position P (manual transmission to
Neutral).
X Open the hood (Y page 192). 284
