Warning!
G
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel
pump nozzle, which could cause personal
injury. i
Make sure to close the fuel filler flap before
locking your vehicle as the flap locking pin pre-
vents closing after you have locked the vehicle.

problem. For more information, see “Practical
hints” (page 307).
253 Operation
Engine compartment
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.
Oil consumption of the SLR is slightly
higher than other vehicles. Please check
the engine oil level frequently.Checking the engine oil level
When checking the oil level,
the vehicle must be parked on level
ground
the engine must be at normal operating
temperature (min. 80°C)
Wait for at least 30 seconds with
engine still at idle.
Measure engine oil level with engine
still at idle.The oil dipstick and the cap are located on
the passenger side in the engine
compartment.
1Oil dipstick
2Filler cap
Pull out oil dipstick1 and wipe it off.
Reinsert the oil dipstick fully into the
guide.
Pull out the oil dipstick again after
3 seconds.
!
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.
254 OperationEngine compartmentOil dipstickThe engine oil level is correct when it is
between lower mark (min) and upper mark
(max) of the oil dipstick.
Top up the engine oil if necessary.Adding engine oil
Using a rag, unscrew filler cap2 from
filler neck.
Add engine oil as required. Be careful
not to overfill with oil.Mercedes-Benz recommends
MOBIL 1 OIL. Use the MB sheet number
229.3 and only SAE 5W-50 engine oils.
MB sheet numbers are printed on the out-
side of oil containers.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
Screw the filler cap back on filler neck.
You will find further information about en-
gine oil in the “Technical data” section
(
page 395) and (
page 393).
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 transmission.
i
The filling quantity between the upper and
lower marks on the oil dipstick is approximately
2.1 US qt (2.0 l).
Warning!
G
The filler cap on the filler neck could be hot.
Use a rag when you unscrew the filler cap.
Otherwise you could burn yourself.!
Only use approved engine oils and oil filters
required for vehicles with Maintenance System.
For a listing of approved engine oils and oil fil-
ters, contact an authorized Mercedes-Benz Cen-
ter or visit www.mbusa.com (USA only).
Using engine oils and oil filters of specification
other than those expressly required for the Main-
tenance System, or changing of oil and oil filter
at change intervals longer than those called for
by the Maintenance System will result in engine
or emission control system damage not covered
by the Mercedes-Benz Limited Warranty.

Cleaning and care of the vehicle
If you have any questions about proper
care of your vehicle, please contact an
authorized Mercedes-Benz Center.Depending on body color the characteris-
tic carbon structure of the body surface
may become visible due to high ambient
temperatures and humidity. This phenom-
enon is related to the technology and
concept of the vehicle’s body.
While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the
underbody and cause lasting damage.
Such damage is caused not only by
extreme and varying climatic conditions,
but also by:
Air pollution
Road salt
Tar
Gravel and stone chippingTo avoid paint damage, you should
immediately remove:
Grease and oil
Fuel
Coolant
Brake fluid
Bird droppings
Insects
Tree resins, etc.
Frequent washing reduces and/or elimi-
nates the aggressiveness and potency of
the above adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:
near the ocean
in industrial areas (smoke, exhaust
emissions)
during winter operation
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or door windows when cleaning the in-
side.
Never use fluids or solvents that are not
designed for cleaning your vehicle.i
Mercedes-Benz recommends that you use
Mercedes-Benz care products. These have been
specially developed to suit Mercedes-Benz vehi-
cles and are state of the art. Mercedes-Benz
care products are available from any
Mercedes-Benz Center.
!
Affixing stickers, magnets, adhesive tape or
similar materials to painted body components
may damage the paintwork.
