32 Getting startedThe “Getting started” section provides an 
overview of the vehicle’s most basic func-
tions. First-time Mercedes-Benz owners 
should pay special attention to the infor-
mation given here.
If you are already familiar with the basic 
functions described here, the “Controls in 
detail” section (
page 98) will provide you 
with further information. The correspond-
ing page references are located at the end 
of each segment.

98 Controls in detailIn the “Controls in detail” section you will 
find detailed information on how to oper-
ate the equipment installed on your vehi-
cle. If you are already familiar with the 
basic functions of your vehicle, this section 
will be of particular interest to you.
To quickly familiarize yourself with the ba-
sic functions of the vehicle, refer to the 
“Getting started” section of this manual. 
The corresponding page numbers are giv-
en at the beginning of each segment.
For more information on locking and 
unlocking, see “Getting started” 
(page 32) and (
page 57).
Locking and unlocking
SmartKey
Your vehicle comes supplied with two 
SmartKeys, each with remote control and 
a removable mechanical key.
The locking tabs for the mechanical key 
portion of the two SmartKeys are a 
different color to help distinguish each 
SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is 
advisable to only unlock the vehicle when 
you are in close proximity to it.
The SmartKey centrally locks and unlocks:

Step 3:
Hold the end of the hand-held remote 
control5 of the device you wish to 
train approximately 2 to 5 in (5 
to12 cm) away from the signal trans-
mitter button (2, 3 or4) to be pro-
grammed, while keeping the indicator 
lamp1 in view.
Step 4:
Using both hands, simultaneously 
press the 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.
The indicator lamp1 will flash, first 
slowly and then rapidly.Step 5:
After the indicator lamp1 changes 
from a slow to a rapidly flashing light, 
release the hand-held remote control 
button and the signal transmitter but-
ton.Step 6:
Press and hold the just-trained signal 
transmitter button (2, 3 or4) and 
observe the indicator lamp1.
If the 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 re-
leased.
iThe indicator lamp1 flashes immedi-
ately the first time the signal transmit-
ter button is programmed. If this button 
has already been programmed, the in-
dicator lamp will only start flashing af-
ter 20 seconds.
iIf the 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.

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:
Step 4:
Press and hold the signal transmitter 
button (2, 3 or4). Do not release 
this button until it has been successful-
ly trained.
While still holding down the signal 
transmitter button (2, 3 or4), 
“cycle” your hand-held remote control 
button6 as follows: Press and hold 
button6 for 2 seconds, then release 
it for 2 seconds, and again press and 
hold it for 2 seconds. Repeat this se-
quence on the hand-held remote con-
trol until the frequency signal has been 
learned. Upon successful training, the 
indicator lamp1 will flash slowly and 
then rapidly after several seconds.
iSome garage door openers (or other 
rolling code equipped devices) may re-
quire you to press, hold for 2 seconds 
and release the same signal transmit-
ter button a third time to complete the 
training process.

Proceed with programming step 5 and 
step 6 to complete. Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow 
these steps:
Switch on the ignition (
page 33).
Press and hold the desired signal 
transmitter button (2, 3 or4). 
Do not release the button.
The indicator lamp1 will begin to 
flash after 20 seconds. Without releas-
ing the signal transmitter button, pro-
ceed with programming starting with 
step 3.Operation of integrated remote control
Switch on the ignition (
page 33).
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.
iUpon completion of programming the 
integrated remote control, make sure 
you retain the hand-held remote con-
trol that came with the garage door 
opener, gate operator or other device. 
You may need it for use in other vehi-
cles, for future programming of an 
integrated remote control, or simply for 
continued use as a hand-held remote 
control to operate the respective 
device in other situations.
