Operation of integrated remote control
Switch on the ignition (
page 40).

Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.Erasing the integrated remote control
memory

Switch on the ignition (
page 40).

Simultaneously press and hold down
the outer signal transmitter buttons2
and 4, for approximately 20 seconds,
until the indicator lamp1 flashes rap-
idly. Do not hold for longer than
30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:


Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.


Put a new battery in the hand-held re-
mote control5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.


While performing step 3, hold the
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
iIf you sell your vehicle, erase the codes
of all three channels.

244 OperationEngine compartmentHood 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!

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

267 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
issued to alert you to a decrease in tire
inflation pressure in one or more of the
tires.
You can call up the tire inflation pressure
monitoring display using the control
system (
page 137).

Switch on the ignition (
page 40).

Press buttonè orÿ on the
multifunction steering wheel
repeatedly until the standard display
menu appears in the multifunction
display (
page 117).

Press button k repeatedly until the
current tire inflation pressures for each
tire appear in the multifunction display.
iAfter you have reactivated the tire infla-
tion pressure monitor, the current tire
inflation pressures will only be shown
after a few minutes driving time.
During this time you will see the
following message in the multifunction
display:Tire pressure
displayed only
after driving
a few minutesiPossible 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
control 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 137).


289 Operation
Maintenance
Maintenance
In 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:

period of time, do not disconnect the
consumer battery. 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 358).
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.

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.
