247 Operation
Engine compartment
Checking the engine oil level
When you check the oil level, the vehicle
must

be parked on level ground


be at normal operating temperature
(min. 80°C)

Wait for at least 30 seconds with en-
gine still at idle.

Measure engine oil level with engine
still at idle.The dipstick and the cap are located on the
passenger side in the engine compart-
ment.
1Dipstick
2Filler cap

Pull out dipstick1 and wipe it off.

Reinsert the dipstick fully into the
guide.

Pull out the dipstick again after three
seconds.
DipstickThe engine oil level must be between the
lower (min) and upper (max) marks.
Top up the engine oil if necessary.iThe difference in level between the up-
per and lower marks represents a
volume of about 1.1 US qt (1.0 l).

Cleaning and care of the vehicle
If you have any questions about proper
care of your SLR, please contact an autho-
rized 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 con-
cept 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 under-
body 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 to prevent corrosion.
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 vehicles and are
state of the art. Mercedes-Benz care
products are available from any
Mercedes-Benz Center.

Problem
Possible cause
Suggested solutions
<
The red Airbrake warning
lamp comes on while driving
and you hear a warning
sound.
The Airbrake or the central locking system
is malfunctioning.

Notify an authorized Mercedes-Benz Center
immeditaly.
>
The red gearshift indicator
lamp comes on while you are
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.
A
The yellow reserve fuel warn-
ing lamp lights up while you
are driving.
The fuel level has fallen into the reserve
range.

Refuel at the nearest gas station
(page 240).
=
The engine oil temperature
symbol comes on in the
tachometer while you are
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.

380 Technical dataFuels, 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 -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°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 Service Booklet for re-
placement interval.Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Service Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see Facto-
ry Approved Service Products pamphlet)
are used to renew the coolant concentra-
tion or bring it back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approximately
- 22°F [-30°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 anticorro-
sion/antifreeze.If the coolant level is low, water and
MB 325.0 anticorrosion/antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Center.
