!If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks immediately. Notify an
authorized Mercedes-Benz Center immediately.
Do not add brake fluid as this will not solve the
problem. For more information, see “Practical
hints” (
page 303).


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 Operation
Engine compartment
Oil dipstick
The 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.
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 391) and (page 389).
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.
iThe 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, refer to the Factory Approved Service
Products pamphlet (USA only) 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, 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.
!Excess oil must be siphoned or drained off.
It could cause damage to the engine or emission
control system not covered by the
Mercedes-Benz Limited Warranty.


293 Operation
Maintenance
Maintenance service term exceeded
If you have exceeded the suggested main-
tenance service term, you will see the fol-
lowing message in the right multifunction
display:
Service exceeded by .. days
Service exceeded by .. miles
Any authorized Mercedes-Benz Center will
reset the maintenance service indicator
following a completed maintenance
service.Calling up the maintenance service due
date
Switch on the ignition (page 40).
Press buttonè orÿ on the
multifunction steering wheel repeated-
ly until the standard display appears in
the multifunction display (
page 117).
Press button k or j on the
multifunction steering wheel until the
maintenance service indicator service
symbol 9 appears in the left multi-
function display and the maintenance
service deadline appears in the right
multifunction display.
iIf the vehicle is not be used for a longer pe-
riod of time, do not disconnect the consumer
battery. Instead, maintain the condition of the
battery by using the battery charger approved by
Mercedes-Benz for use on the SLR and supplied
with the car (
page 369). This charger automat-
ically controls the charge rate, and can be left
connected to the car for long periods without
damage to the battery.
If the battery supplying the vehicle’s electrical
consumers is disconnected, the days of discon-
nection will not be included in the count shown
by the maintenance service indicator. To arrive
at the true maintenance service deadline, you
will need to subtract these days from the days
shown in the maintenance service indicator.
Do not confuse the maintenance service indica-
tor with the engine oil level indicator:.

394 Technical data
Fuels, coolants, lubricants, etc.
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 -35°F (-37°C) and
corrosion protection.
If the antifreeze mixture is effective to
-35°F (-37°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
determine the replacement interval. The
replacement 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 are used to
renew the coolant concentration or bring it
back up to the proper level.
For information on other Mercedes-Benz
approved products of equal specification,
refer to the Factory Approved Service
Products pamphlet (USA only) or contact
an authorized Mercedes-Benz Center.To provide important corrosion protection,
the solution must be at least 50% anticor-
rosion/antifreeze (equivalent to freeze
protection to approximately
-35°F [-37°C]). If you use a solution that is
more than 55% anticorrosion/antifreeze
(freeze protection to approximately
-49°F [-45°C]), the engine temperature
will increase due to the lower heat transfer
capability of the solution. Therefore, do not
use more than this amount of
anticorrosion/antifreeze.
!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.
