For more information on engine oil level,
see “Engine oil” (
page 246).
Brake fluid
iMore information on gasoline can be
found in the Factory Approved Service
Products pamphlet.
Leaving the engine running and the fuel
cap open can cause theú malfunc-
tion indicator lamp (USA only) or
the± malfunction indicator lamp
(Canada only) to illuminate.
For more information, see “Practical
hints” (
page 299).
iOpening the hood, see (
page 243).

minimum mark or below, have the
brake system checked for brake pad
thickness and leaks immediately.
Notify an authorized Mercedes-Benz

Hood OpeningWarning!
G
Do not pull the release lever while the
vehicle is in motion. Otherwise the hood
could be forced open by passing air flow.Warning!
G
The exhaust areas on the engine hood and
between the doors and front wheels get very
hot. Avoid contact with them, otherwise
there is the risk of severe burns.
Warning!
G
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running. Make sure the hood is
properly closed before driving. When closing
the hood, use extreme caution not to catch
hands or fingers.
The radiator fan may also start at any time
automatically, even after the SmartKey has
been removed from the starter switch. Stay
clear of fan blades.Warning!
G
Engine components may become very hot.
Avoid contact with them, otherwise there is
the risk of severe burns.
Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnos-
tic socket) of the ignition system

with the engine running


while starting the engine


if ignition is “on” and the engine is
turned manually

246 OperationEngine compartmentClosing
Pull the hood upwards in the center,
against the resistance of the gas-filled
spring struts.

Hold the front center part of the hood
with both hands and push it back-
wards. After pushing the hood back-
wards about half-way, you will feel the
hood passing a crest and the resulting
force pulling the hood away from you.
At that point, let go of the hood and let
it fall onto the latches.
The hood should now be locked and en-
tirely closed.

Check that the hood is properly closed.
If the hood is not properly engaged, re-
peat the closing procedure.
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.
Regularly check the engine oil level, at
least every 1 800 miles (3 000 km).
Warning!
G
Be careful that you do not close the hood on
anyone.
!Make sure the rollers at the rear of the
hood are engaged and the guide pins
line up with the guide holes. Otherwise
the hood may be damaged.
!Do not use any special lubricant addi-
tives, 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.

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

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).

248 OperationEngine compartmentAdding 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 377) and (
page 375).
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.
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 filters,
refer to the Factory Approved Service
Products pamphlet 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 Maintenance
System, or changing of oil and oil filter
at change intervals longer than those
called for by the Maintenance System
will result in engine damage not cov-
ered by the Mercedes-Benz Limited

iYou should not disconnect the consum-
er battery if you do not intend to use
your SLR for a longer period. 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 356).
This charger automatically controls the
charge rate, and can be left connected
to the car for long periods without dam-
age to the battery.
If the battery supplying the vehicle’s
electrical consumers is disconnected,
the days of disconnection will not be in-
cluded in the count shown by the ser-
vice indicator. To arrive at the true
service deadline, you will need to sub-
tract these days from the days shown
in the service indicator.
Do not confuse the maintenance
service indicator with the engine oil
level indicator:.
