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 transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and be-
gin directly with step 3.
Step 3:
Hold the end of hand-held remote
control5 of the device you wish to
train approximately 2 to 5 inches
(5 to12 cm) away from the signal trans-
mitter button (2, 3 or4) to be pro-
grammed, while keeping indicator
lamp1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button6 and the desired signal trans-mitter button (2, 3 or4). Do not
release the buttons until step 5 is com-
pleted.
Indicator lamp1 will flash, first slowly
and then rapidly.
Step 5:
After indicator lamp1 changes from a
slow to a rapidly flashing light, release
the hand-held remote control button
and the signal transmitter button.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe indicator lamp1.If indicator lamp1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3 or4) is pressed and
released.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
iIndicator lamp1 flashes immediately the
first time the signal transmitter button is pro-
grammed. If this button has already been pro-
grammed, the indicator lamp will only start
flashing after 20 seconds.iIf indicator lamp1 flashes rapidly for about
2 seconds and then turns to a constant light,
continue with programming steps 8 through 12
as your garage door opener may be equipped
with the “rolling code” feature.

Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn” or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
Operator’s Manual.
Step 9:
Press the “training” button on the ga-
rage door opener motor head unit.
The “training light” is activated.You have 30 seconds to initiate the
following step.
Step 10:
Return to the vehicle and firmly press,
hold for 2 seconds and release the pro-
grammed signal transmitter button
(2, 3 or4).
Step 11:
Press, hold for 2 seconds and release
same signal transmitter button a sec-
ond time to complete the training
process.Step 12:
Confirm the garage door operation by
pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
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:
iSome garage door openers (or other rolling
code equipped devices) may require you to
press, hold for 2 seconds and release the same
signal transmitter button a third time to com-
plete the training process.

Vehicle care
Ornamental moldings
For regular cleaning and care of
ornamental moldings, use a damp cloth.Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water.Cleaning the Parktronic system*
sensors (CLK 63 AMG (USA), Canada all

bumper
Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water and a
soft, non-scratching cloth to clean
sensors1 on the bumpers.
!Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome
cleaner. If in doubt whether an ornamental
molding is chrome-plated, contact an authorized
Mercedes-Benz Center.
!Only use window cleaning solutions that are
suitable for plastic lamp lenses. Window
cleaning solutions which are not suitable may
damage the plastic lamp lenses of the
headlamps. Therefore, do not use abrasives,
solvents or cleaners that contain solvents.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry
cloth or sponge.
Otherwise you may scratch or damage the lens
surface.
