Cleaning and care of the vehicle
If you have any questions about proper
care of your SLR, 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 chipping
To 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
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible.
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 windows when cleaning the inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
iMercedes-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.

ProblemPossible cause/consequenceSuggested solutions
ú(USA only)
±(Canada only)
The yellow engine malfunc-
tion indicator lamp comes on
while the engine is running.
There is a malfunction in:

The fuel injection system

The ignition system

The emission control system

Systems which effect emissions
Such malfunctions may result in excessive
emissions values and may switch the
engine to its limp-home (emergency
operation) mode.
Have the vehicle checked as soon as possi-
ble by an authorized Mercedes-Benz Center.
An on-board diagnostic connector is used by
the service station to link the vehicle to the
shop diagnostics system. It allows the accu-
rate identification of system malfunctions
through the readout of diagnostic trouble
codes. It is located in the front left area of
the footwell next to the parking brake pedal.
Your fuel tank is empty.After refueling, start, turn off, and restart the
engine three or four times in succession.
The limp-home mode is canceled. You do not
need to have your vehicle checked.
iSome states may by law require you to visit
a workshop immediately as soon as the engine
malfunction indicator lamp comes on. Check
local requirements.

is malfunctioning.Contact an authorized Mercedes-Benz
Center immediately.
>The red gearshift indicator
lamp comes on while driving.You are driving with the manual shift pro-
gram. The engine is in the overrevving
range.Shift to the next higher gear. Otherwise the
fuel supply will be interrupted to prevent the
engine from overrevving.
AThe yellow fuel reserve warn-
ing lamp comes on while
driving.The fuel level has dropped below the
reserve mark.Refuel at the nearest gas station
(

=The engine oil temperature
indicator comes on in the
tachometer while driving.The engine oil has not yet reached its
operating temperature.Warm up the engine and do not drive at full
power until the operating temperature has
been reached.
The symbol will go out as soon as the engine
oil has reached its operating temperature.

HLow tire pressure telltale for the
TPMS illuminates continuously.The TPMS detects a loss of pressure in at
least one tire.Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers. Observe the traffic
situation around you.
Read and observe messages in the
multifunction display.
The low tire pressure telltale goes out
once the TPMS has been reactivated after
the tire inflation pressure has been
corrected.
Warning!G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly underinflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly underinflated tire causes the tire to over-
heat and can lead to tire failure.Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.

Flat tire
Contact an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT kit.
Bring used TIREFIT materials to an
authorized Mercedes-Benz Center for
proper disposal.
Replace your TIREFIT container every
4 years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Warning!G
Follow recommend tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being
overheated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit or vehicle capacity
weight as indicated on the placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout.
Warning!G
Do not exceed vehicle speed of 50 mph
(80 km/h). A TIREFIT repair is not designed
to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.
