2005 MERCEDES-BENZ CLK500 CABRIOLET ignition

286 Controls in detailUseful featuresProgramming or reprogramming the in-
tegrated remote control
Step 1:
Switch on the ignition (
page 36).
Step 2:

If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator lamp 1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory. If you later wish to program a
second and/or third hand-held trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.Step 3:

Hold the end of the hand-held remote
control transmitter6 of the device
you wish to train approximately 2 to
5 in (5 to12 cm) away from the surface
of the integrated remote control locat-
ed on the interior rear view mirror,
keeping the indicator lamp1 in view.
Step 4:

Using both hands, simultaneously
press the hand-held transmitter
button5 and the desired integrated
signal transmitter button (2, 3
or4). Do not release the buttons until
completing step 5.
The indicator lamp1 on the integrat-
ed remote control will flash, first slowly
and then rapidly.Step 5:

When the indicator lamp1 flashes
rapidly, release both buttons.
Step 6:

Press and hold the just-trained inte-
grated signal transmitter button and
observe the indicator lamp1.
If the indicator lamp1 stays on con-
stantly, programming is complete and
your device should activate when the
integrated signal transmitter button is
pressed and released.iThe indicator lamp1 flashes the first
time the signal transmitter button is
programmed. If this button has already
been programmed, the indicator lamp
will only start flashing after 20 sec-
onds.

288 Controls in detailUseful featuresGate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:
Continue to press and hold the inte-
grated signal transmitter button (2,
3 or4) while you press and re-press
(“cycle”) your hand-held remote con-
trol transmitter6 every two seconds
until the frequency signal has been learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.

Proceed with programming step 5 and
step 6 to complete.
Operation of integrated remote control

Switch on the ignition (
page 36).

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 36).

Simultaneously hold down the signal
transmitter buttons2 and 4, for ap-
proximately 20 seconds, until the indicator lamp1 blinks rapidly. Do not
hold for longer than 30 seconds.
The codes of all three channels are
erased.
Reprogramming a single integrated
signal transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:

Press and hold the desired signal trans-
mitter button (2, 3 or4). Do not re-
lease the button.

The indicator lamp will begin to flash af-
ter 20 seconds. Without releasing the
integrated signal transmitter button,
proceed with programming starting
with step 3.iIf you sell your vehicle, erase the codes
of all three channels.

306 OperationEngine compartment
Closing
Let the hood drop from a height of
approximately 1 ft (30 cm).
The hood will lock audibly.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
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.
Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from vehicle and do not open the hood
until the engine has cooled. If necessary,
call the fire department.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
Warning!
G
Be careful that you do not close the hood on
anyone.
iDo 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.
More information on this subject is
available at any Mercedes-Benz
Center.

notify you when your next maintenance
service is due.Starting approximately one month before
your next maintenance service is due, one
of the following messages will appear in
the multifunction display while you are
driving or when you switch on the ignition
(example service A):
Service A in XXXXX miles (km)
Service A in XXX days

cles): The interval between
maintenance services depends on your
driving habits. A gentle driving style,
moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

The yellow engine
malfunction indi-
cator lamp comes
on while driving.
There is a malfunction in:

The fuel management system


The ignition system


The emission control system


Systems which affect emissions
Such malfunctions may result in ex-
cessive emissions values and may
switch the engine to its Limp-Home
Mode (emergency operation).

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.
A loss of pressure has been
detected in the fuel system. The fuel
cap may not be closed properly or
the fuel system may be leaky.

Check the fuel cap (
page 302).
If it is not closed properly:

Close the fuel cap.
If it is closed properly:

Have the fuel system checked by an autho-
rized Mercedes-Benz Center.
Your fuel 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.
