Programming or reprogramming the
integrated remote control
Step 1:
Switch on ignition.
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 light
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.
iCertain types of garage door openers
are incompatible with the integrated
opener. If you should experience
difficulties with programming the
transmitter, contact your authorized
Mercedes-Benz Center, or call
Mercedes-Benz Customer Assistance
Center (in the USA only) at
1-800-FOR-MERCedes, or Customer
Service (in Canada) at
1-800-387-0100.

Useful features
Gate 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
integrated signal transmitter to pick up the
signal 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
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:Step 4:

Continue to press and hold the
integrated signal transmitter button
(2, 3 or4) while you press and
re-press (“cycle”) your hand-held
remote control 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 ignition.

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

236 Controls in detailUseful featuresErasing the integrated remote control
memory
Switch on ignition.

Simultaneously hold down the signal
transmitter buttons2 and 4, for
approximately 20 seconds, until the
indicator lamp1 flashes 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
transmitter button (2, 3 or4).
Do not release the button.

The indicator lamp will begin to flash
after 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.

253 Operation
Engine compartment
Closing
Let the hood drop from a height of
approximately 1ft (30cm).
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
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 will
restrict your warranty entitlement.
More information on this subject is
available at any Mercedes-Benz
Center.

265 Operation
Maintenance
Maintenance
We strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times/mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.
Approximately one month before your next
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 XX DAYS
SERVICE A IN XX MILES (KM)
SERVICE A DUE NOW!
The type of service due is indicated in the
multifunction display:
9Minor service (A)
´Major service (B)
Clearing the service indicator
The service indicator is automatically
cleared

after ten seconds when you switch on
the ignition or when reaching the
service threshold while driving


after 30 seconds, once the suggested
service term has passed
You can also clear it yourself.

Press the reset button on the
instrument cluster (
page 22).
Service term exceeded
If you have exceeded the suggested
service term, you will see the following
message in the multifunction display:SERVICE A EXCEEDED BY XX DAYS
SERVICE A EXCEEDED BY XX MI (KM)An acoustic signal will also sound.
iThe interval between 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.

266 OperationMaintenanceThe Mercedes-Benz Center will reset the
service indicator following a completed
service.Calling up the service indicator
Switch on ignition.
The standard display of the control
system appears (
page 113).

Press buttonk orj on the mul-
tifunction steering wheel until the FSS
indicator appears in the multifunction
display.
Resetting the service indicator
In the event that the service on your
vehicle is not carried out by an authorized
Mercedes-Benz Center, you can reset the
service indicator yourself.
Switch on ignition.
The standard display of the control
system appears (
page 113).

Press buttonk orj on the mul-
tifunction steering wheel until the FSS
indicator appears in the multifunction
display.

Press reset button for about three
seconds.
This message appears in the multifunc-
tion display:SERVICE INTERVAL?
RESET WITH R BUTTON FOR 3 SEC.

To confirm, press reset button until you
hear a signal.
The service indicator now displays the
reset interval.
iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the service indica-
tor. To arrive at the true service
deadline, you will need to subtract
these days from the days shown in the
service indicator.
Do not confuse the service indicator
with the engine oil level indicator:.
iIf the service indicator was
inadvertently reset, have a
Mercedes-Benz Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next
service interval which will result in
engine damage not covered by the
Mercedes-Benz Limited Warranty.
