275 Operation
Engine compartment
Pull hood release1.
The hood is unlocked.
2Lever for opening the hood
Push lever2 on the hood upwards.
Pull up on the hood and then release it.
The hood will be automatically held
open at shoulder height by gas-filled
struts. Closing
Let the hood drop from a height of ap-
proximately 1
1/2ft (50 cm).
The hood will lock audibly.
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 needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when
the vehicle is new
the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
!
To avoid damage to the windshield wipers or
hood, never open the hood if the wiper arms are
folded forward away from the windshield.
Warning!
G
When closing the hood, use extreme caution
not to catch hand or fingers. Be careful that
you do not close the hood on anyone.
Make sure the hood is securely engaged be-
fore driving. 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.
i
Do not use any special lubricant additives,
as these may damage the drive assemblies. Us-
ing special additives not approved by
Mercedes-Benz may cause damage not covered
by the Mercedes-Benz Limited Warranty. More
information on this subject is available at any
Mercedes-Benz Center.
278 OperationEngine compartmentChecking engine oil level with the oil
dipstick (SL 550 only)
When checking the oil level
the vehicle must be parked on level
ground
the vehicle must have been stationary
for at least 5 minutes with the engine
turned off
1Oil dipstick
2Upper mark
3Lower mark
Open the hood (
page 274).
Pull out oil dipstick 1.
Wipe oil dipstick 1 clean.
Fully insert oil dipstick 1 into the dip-
stick guide tube.
Pull out oil dipstick 1 again after ap-
proximately 3 seconds to obtain accu-
rate reading.
The oil level is correct when it is be-
tween lower mark 3 (min.) and upper
mark 2 (max.) of the oil dipstick.
If necessary, add engine
oil (
page 278).
For more information on engine oil, see
“Technical data” section (
page 444) and
(
page 446).
For information on messages in the multi-
function display concerning engine oil, see
the “Practical hints” section (
page 375).Adding engine oil
i
In vehicles without an oil dipstick, the engine
oil level is measured via the control
system (
page 276).
i
The filling quantity between the upper and
lower marks on the oil dipstick is approximately
2.1 US qt. (2.0 l).
!
Only use approved engine oils and oil filters
required for vehicles with Maintenance System
(U.S. vehicles) or FSS (Canada vehicles). For a
listing of approved engine oils and oil filters, re-
fer to the Factory Approved Service Products
pamphlet in your vehicle literature portfolio, or
contact an authorized Mercedes-Benz Center.
Using engine oils and oil filters of specification
other than those expressly required for the Main-
tenance System (U.S. vehicles) or FSS (Canada
vehicles), or changing of oil and oil filter at
change intervals longer than those called for by
the Maintenance System (U.S. vehicles) or FSS
(Canada vehicles) will result in engine or emis-
sion control system damage not covered by the
Mercedes-Benz Limited Warranty.
279 Operation
Engine compartment
Example illustration SL 5501Filler capExample illustration SL 55 AMG1Filler cap
Unscrew filler cap1 from filler neck.
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.
Screw filler cap1 back on filler neck.
For more information on engine oil, see the
“Technical data” section (
page 444) and
(
page 446).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the automatic transmission. Oil level in the ABC system
The oil level in the ABC system does not
need to be checked. If there is visible oil
loss or if malfunction messages appear in
the display, have an authorized
Mercedes-Benz Center check the ABC
system.
!
Excess oil must be siphoned or drained off.
It could cause damage to the engine and catalyt-
ic converter not covered by the Mercedes-Benz
Limited Warranty.
447 Technical data
Fuels, coolants, lubricants, etc.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Only brake fluid approved by
Mercedes-Benz is recommended. Your
authorized Mercedes-Benz Center will
provide you with additional information.
Premium unleaded gasoline
Warning!
G
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus
reducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact,
extinguish all smoking materials. Never
allow sparks, flame or smoking materials
near gasoline!
!
To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be
used. If premium unleaded is not available and
low octane fuel is used, follow these precau-
tions:
have the fuel tank only partially filled with un-
leaded regular and fill up with premium un-
leaded as soon as possible
avoid full throttle driving and abrupt acceler-
ation
do not exceed an engine speed of 3000 rpm
if the vehicle is loaded with a light load such
as two occupants and no luggage
do not exceed
2/3 of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain
449 Technical data
Fuels, coolants, lubricants, etc.
In areas where carbon deposits may be en-
countered due to lack of availability of gas-
olines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Refer to Factory
Approved Service Products pamphlet for a
listing of approved product(s). Follow di-
rections on product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and
may be harmful to the engine operation.
Damage or malfunction resulting from
poor fuel quality or from blending addition-
al fuel additives other than those tested
and approved by us for use on
Mercedes-Benz vehicles listed in the
Factory Approved Service Products pam-
phlet are not covered by the
Mercedes-Benz Limited Warranty.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-
vides:
corrosion protection
freeze protection
boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in the boil-over
protection. Refer to Maintenance Booklet
for replacement interval.
Coolant system design and coolant used
stipulate the replacement interval. The re-
placement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration or bring it back up to the proper
level.
!
Add premixed coolant solution only. Adding
water and MB 325.0 Anticorrosion/Antifreeze
separately from each other, could cause engine
damage not covered by the Mercedes-Benz
Limited Warranty.
