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

265 Operation
Tires and wheels
Checking tire inflation pressure
electronically
The tire inflation pressure monitor only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is is-
sued to alert you to a decrease in pressure
in one or more of the tires.
Tire inflation pressure inquiries are made
using the multifunction display
(page 117). The present inflation pres-
sures are displayed only after a few min-
utes travel time.

Switch on the ignition (
page 40).

Make sure you are viewing the stan-
dard display menu (
page 117).

Press k button until the current in-
flation pressures for each tire appear in
the tachometer display field.
iPossible differences between the read-
ings of a tire inflation pressure gauge of
an air hose, e.g. gas station equipment,
and the vehicle’s control system can
occur. The readings issued by the con-
trol system are more precise.
iYou can select the unit of measure
(bar/psi) used for the tire inflation
pressure by changing the setting in the
control system (
page 136).
Warning!
G
When the tire inflation pressure monitoring
system warning light is lit, one or more of
your tires is significantly under-inflated. You
should stop and check your tires as soon as
possible, and inflate them to the proper tire
inflation pressure as indicated on the vehi-
cle’s tire information placard. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended tire inflation pressure as specified
in the vehicle placard and owner’s manual.


286 OperationMaintenanceIn order to maintain the performance and
safety of your SLR, we strongly recom-
mend that you have your vehicle serviced
by an authorized Mercedes-Benz Center,
every 12 months, even if the vehicle has
covered less than 10 000 miles
(15 000 km) in that time.
The maintenance service indicator will
notify you when your next maintenance
service is due within the next 12 months or
10 000 miles (15 000 km), whichever
comes sooner.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.Before your next maintenance service is
due, one of the following messages will ap-
pear in the right multifunction display while
you are driving or when you switch on the
ignition:
Service in.. days
Service in.. km

When the maintenance service is due, the
display message Service Due now!
ap-
pears.Clearing the maintenance service

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:.

What to do if ...
Problem
Possible cause
Suggested solutions
ú
(USA only)
±
(Canada only)
The yellow engine malfunc-
tion indicator lamp comes on
while driving.
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 en-
gine to its limp-home (emergency opera-
tion) 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.
Your gas tank is empty.

After refuelling, 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.
The fuel cap is not closed tightly.

Check the fuel cap.

304 Practical hintsWhat to do if ...Vehicle status messages in the multifunction display
Warning and malfunction messages
appear in the multifunction display located
in the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 124) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 29). Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button. They are then
stored in the vehicle status message mem-
ory (
page 124). Remember that clearing
a message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.
Warning!
G
All categories of messages contain
important information which should be
taken note of and, where a malfunction is
indicated, addressed as soon as possible at
an authorized Mercedes-Benz Center.
