Maintenance Booklet4We want you to enjoy your Mercedes-Benz
SLR. Vehicle safety and operational
reliability are two very important factors
and to maintain them, regular
maintenance services are necessary.
We continuously strive to improve our
product and ask for your understanding
that we reserve the right to make changes
in the periodic maintenance work which is
required for our vehicles. The information
in this manual is accurate as of the press
time. At the time of your scheduled
maintenance appointments with your
authorized Mercedes-Benz Center, the
most current maintenance work
information will be utilized for your
vehicle’s age or mileage. Please check
with your authorized Mercedes-Benz
Center for any changes to the periodic
maintenance work required for your
vehicle.
Your Mercedes-Benz SLR comes equipped
with the Mercedes-Benz SLR
Maintenance System. The Maintenance
System tracks distance driven and the time elapsed since your last service. The
next necessary maintenance service is
indicated in the maintenance service
indicator in the instrument cluster.
Additional work that is not calculated by
the Maintenance System is required at
each maintenance interval. Please refer to
“Additional Work to be Performed” on
page 55 for more details.
Following each service, your authorized
Mercedes-Benz Center will reset the
Maintenance System service indicator by
confirming the service items performed.
!
If the Maintenance System service
counter was inadvertently reset, have a Mer-
cedes-Benz Center correct it. Please only
reset if the proper maintenance service has
been performed. Resetting the system without
performing the proper service will result in
engine and/or other vehicle damage not cov-
ered by the Mercedes-Benz New Car Limited
Warranty.
Introduction

5 Maintenance Booklet
A detailed listing of service procedures
performed are contained in this booklet,
starting on page 47.
Additional work
Additional work means any work that is
not calculated by the Maintenance Sys-
tem. This work is listed in the section
“Additional Work to be Performed”, see
page 55. This type of work has to be car-
ried out according to the individual vehi-
cle type, due to the specific technical
parameters, wear processes or special
equipment.
Special service requirements
Brake fluid should be replaced every two
years, preferably in the spring, see page
56. We recommend that you only use
brake fluid approved by Mercedes-Benz.
A reminder for the next scheduled brake
fluid replacement is affixed in the engine
compartment. Coolant should be checked for the prop-
er concentration before the start of the
winter season (or once a year in hot re-
gions). Have the coolant (water/anticor-
rosion/antifreeze mixture) replaced
every 4 years, see page 56.
Replacement of coolant (water/anticor-
rosion/antifreeze mixture) may be re-
quired more frequently if coolant is not
maintained according to instructions
and/or other than approved anticorro-
sion/antifreeze products for your vehicle
are being used. For instuctions on cool-
ant, see “Coolants” in your vehicle Oper-
ator’s Manual. For a listing of approved
anticorrosion/antifreeze products for
your vehicle, refer to
www.startekinfo.com or
www.mbusa.com/ownersonline, or
contact your authorized Mercedes-Benz
Center.
Introduction

Maintenance Booklet8IntroductionRegular checks
In addition to the services, we recom-
mend that you check the following items
regularly (for example: weekly, when re-
fueling, or before any long journey):
• Engine oil level - Check the engine oil
level using the engine oil dipstick. Fur-
ther information about engine oil level
measurement can be found in the vehi-
cle Operator’s Manual.
• Coolant level - Please refer to the Op-
erator’s Manual for the correct proce-
dure to check the coolant level.
• Brake fluid level - If brake fluid has to
be added, see an authorized Mer-
cedes-Benz Center to determine the
cause, e.g. leaks or worn brake pads.• Windshield washing system - If the
washer fluid level drops below 1/3, the
windshield washer fluid level warning
lamp will illuminate. Add washer fluid
mixed with Mercedes-Benz windshield
washer solvent/concentrate, test
function and check wiper blades.
• Check lights
• Tire condition and pressures –
Check at least every other week.
Please refer to section “Tires and
wheels” in the Operator’s Manual for
guidelines and correct procedures to
check tire condition and pressures.
For more information on selecting the
proper fluids, lubricants and oils for your
vehicle please refer to
www.startekinfo.com or
www.mbusa.com/ownersonline, or see
your authorized Mercedes-Benz Center.

Emission System Maintenance
d) The operation of the emission con-
trol system must not be altered in
any way. Alterations are not permissi-
ble by law. In addition, alterations may
result in damage to the catalysts, in-
creased fuel consumption, and im-
paired engine running conditions.

e) Irregular engine running conditions
should be corrected immediately by
an authorized Mercedes-Benz Cent-
er. Such irregular running conditions
can influence the proper function of the
emission control system.
If the “CHECK ENGINE” indicator lamp in
the instrument cluster illuminates when
the engine is running, it indicates a possi-
ble malfunction of the engine manage-
ment system or emission control system.
We recommend that you have the mal-
function checked as soon as possible.

tire rotation at least once in between maintenance services and at every maintenance service based on Mercedes-Benz maintenance intervals.
