7 Maintenance Booklet
Tire manufacturer’s rotation
recommendations will necessitate a tire
rotation at least once in between
maintenance services and at every
maintenance service based on
Mercedes-Benz SLR maintenance
intervals
.
The first tire rotation is at no charge pro-
vided it is performed at an authorized
Mercedes-Benz Center prior to 6,500
miles on the vehicle odometer.
For your convenience, this Maintenance
Booklet contains a tire rotation confirma-
tion page on which you can record the
date and mileage when tire rotations
were performed.
Spark Plugs should be replaced accord-
ing to schedule on page 60. Severe oper-
ating conditions (frequent starting and
stopping, excessive idling, sustained fast
highway driving) may call for spark plugs
to be replaced correspondingly sooner.Engine oils and oil filters are specifical-
ly tested for their suitability in our en-
gines and durability for our service
intervals. Therefore, only use approved
engine oils and oil filters required for ve-
hicles with Maintenance System. For a
listing of approved engine oils and oil fil-
ters, refer to the Factory Approved Serv-
ice products pamphlet, or contact an
authorized Mercedes-Benz Center.
Using engine oils and oil filters of specifi-
cation other than those expressly re-
quired for the Maintenance System or
changing of oil and oil filter at change in-
tervals longer than those called for by the
Maintenance System will result in engine
damage not covered by the Mercedes-
Benz Limited Warranty
.Introduction

Maintenance Booklet12Emission System MaintenanceEmission Control System Caution -
Gasoline Engines
Your Mercedes-Benz SLR vehicle is
equipped with both a three-way catalyst
and a closed loop oxygen sensor system
to comply with current exhaust emission
regulations. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined.
The following has to be adhered to:
a) In all gasoline engine models, use
only premium unleaded gasoline
with an anti-knock index of at least
91 (as displayed on the pump) un-
less otherwise specified. Damage to
the engine could occur if premium un-
leaded fuel is not used. Refer to the
Operator’s Manual for special precau-
tions.
b) Leaded gasoline should not be used
under any circumstances. Damage
to the emission control components
will result.
c) The specified engine maintenance
jobs have to be performed com-
pletely and at the required inter-
vals. Correct ignition timing and
properly functioning spark plugs for in-
stance are important for the service
life of the catalysts. Failure to properly
perform the specified maintenance
jobs may adversely affect the emis-
sion control system on the vehicle and
reduce its service life.

Description of Emission System Maintenance Jobs
The composition of exhaust emissions is
influenced not only by the special emission
control equipment, but also by various en-
gine components and their adjustments.
Therefore, emission system maintenance
must include these engine components.
Some maintenance jobs are actually only
tests. They are important however, be-
cause they allow early detection of dis-
crepancies which can later lead to
increased exhaust emissions. It is general-
ly less expensive to have such items ad-
justed immediately rather than allowing
them to contribute to costly repairs. The
maintenance intervals have been deter-
mined so that the vehicle, under normal
conditions, should operate properly be-
tween services. 0101 Engine oil and filter change
Change the engine oil and oil filter every
10,000 miles. If oil consumption should in-
crease, determine the cause and take nec-
essary corrective steps. Reset the
Maintenance System counter.
0980 Replace air filter element
Under normal dust conditions, replace air
filter element approximately every 20,000
miles or 2 years. Clean air filter cover and
housing prior to removal of air filter ele-
ment.0780 Replace fuel filter
Replace the fuel filter approximately every
60,000 miles or 4 years.
1351 Check engine poly-V-belt condi-
tion
The poly-V-belt is subject to wear and ag-
ing. It must be checked for cracks and
wear at every service. Replace poly-V-belt
if necessary.
1580 Replace spark plugs
Spark plugs are subject to electrode ero-
sion and must be replaced according to
schedule on page 60, or more frequently
as may be required when subject to severe
operating conditions.
