2Portable remote control transmitterThe built-in remote control is capable of operating up to 
three separately controlled objects.
Notes:
Certain 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 Client Assistance Center (in the USA 
only) at 1-800-FOR-MERCedes, or Customer Service (in 
Canada) at 1-800-387-0100.
For operation in the USA only: This device complies 
with Part 15 of the FCC Rules. Operation is subject to 
the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, 
including interference that may cause undesired

Programming or reprogramming the integrated 
remote control:
1.Turn key in starter switch to position 1 or 2.
2.Hold the end of the hand-held transmitter of the 
d evice you w ish  to train approxim ately 2 to 5 inch es 
(5 cm to 12 cm) away from the surface of the 
integrated remote control located on the inside rear 
view mirror, keeping the indicator lamp in view.
3.Using both hands, simultaneously push the hand-
held transmitter button and the desired integrated 
remote control button. Do not release the buttons 
until completing step 4.
4.The indicator lamp on the integrated remote control 
will flash, first slowly and then rapidly. When the 
indicator lamp flashes rapidly, both buttons may be 
released (the rapid flashing lamp indicates 
successful programming of the new frequency 
signal). To program the remaining two buttons, 
follow steps 1 through 4.Note: 
If, after repeated attempts, you do not successfully 
program the integrated remote control device to learn 
the signal of the hand-held transmitter, the garage door 
opener could 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 of this text. (A second person may make the 
following training procedures quicker and easier.)
1.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. If 
there is difficulty locating the transmitting button, 
reference to garage door opener operator’s manual. 
2.Press “training” button on the garage door opener 
motor head unit (which activated the “training 
light”).

Following step 2, there are 30 seconds to initiate 
step 3.
3.Firmly press and release the programmed 
integrated remote control transmit button. Press 
and release same button a second time to complete 
the training process. (Some garage door openers 
may require you to do this procedure a third time to 
complete the training.)
4.Confirm the garage door operation by pressing the 
programmed button on the integrated remote 
control transmitter. 
Canadian programming:
During programming, your hand-held transmitter may 
automatically stop transmitting. Continue to press and 
hold the integrated remote control transmitter button 
(note steps 2 through 4 in the “Programming” portion) 
while you press and re-press (“cycle”) your hand-held 
transmitter every two seconds until the frequency 
signal has been learned. The indicator lamp will f lash 
slowly and then rapidly after several seconds upon 
successful training.Operation of remote control:
1.Turn key in starter switch to position 1 or 2.
2.Select and press the appropriate button to activate 
the remote controlled device. The integrated remote 
control transmitter continues to send the signal as 
long as the button is pressed – up to 20 seconds.
Erasing the remote control memory:
1.Turn key in starter switch to position 1 or 2.
2.Simultaneously holding down the left and right side 
buttons for approximately 20 seconds, or until the 
control lamp blinks rapidly, will erase the codes of 
all three channels.

Retractable hardtop
Important!
A minimum clearance height of 5
1/2 ft. (1.65 m) and an 
additional 10 in (25 cm) length behind the vehicle is 
required to lower or raise the hardtop.
Th e add itional  space is requ ired since th e roof  moves u p 
and the trunk lid back during raising and lowering 
operations.
The raising or lowering operations can only be started 
with the luggage cover and trunk lid closed.
The raising or lowering procedure is immediately 
interrupted by releasing the hardtop switch.
Do not operate the roof while a roof luggage carrier is 
installed.To prevent damage to hardtop or luggage / cargo when 
lowering the roof:
•load trunk only to the height of the luggage cover,
•do not permit luggage / cargo to raise the closed 
luggage cover,
•do not load anything on top of the luggage cover,
•do not place anything on shelf behind roll bars.
Note:
To prevent the hardtop from being lowered 
unintentionally while a roof luggage carrier is installed, 
keep luggage cover in trunk in the open position.
Wa r n i n g !
Before operating the switch for the retractable 
hardtop make sure that no persons due to 
inattention are injured by the moving parts 
(retractable roof, roof frame, and trunk lid).Hands must never be placed near the roof frame, 
upper windshield area, hardtop, shelf behind roll 
bars, or trunk lid while the retractable hardtop is 
being raised or lowered. Serious personal injury 
may occur.

3.Slide hardtop switch back (1) and hold:
•The indicator lamp in the hardtop switch lights 
up.
Note:
If indicator lamp blinks slowly, a malfunction 
has occurred in the system. 
If indicator lamp blinks rapidly, the trunk lid 
and / or the luggage cover may be open, and need 
to be closed.
•The door windows lower.
•The trunk lid opens rearward.
•The hardtop lowers into its storage 
compartment, simultaneously the shelf behind 
roll bars opens, and rear quarter windows lower.
•The shelf behind the roll bars closes.
•The trunk lid closes.
•The indicator lamp in the hardtop switch goes 
out – the opening procedure is completed.If the hardtop switch is held or is released and slid back 
again within approximately 30 seconds, the door 
windows will close.
However, the door windows can also be closed / opened 
later on. Slide hardtop switch twice forward / backward 
and hold.
The rear quarter windows cannot be raised with the 
hardtop lowered.
Notes:
For safety reasons, the hardtop cannot be lowered while 
driving.
Lowering a wet hardtop can result in water reaching the 
vehicle interior. The hardtop should be dry when 
lowering it into the storage compartment.
Wa r n i n g !
To prevent possible accidents, drive the vehicle 
only with the hardtop either completely closed and 
locked, or fully lowered into its storage 
compartment.
