Closing the tailgate and locking the
vehicle from the outside (vehicles with
KEYLESS-GO*)
In vehicles with power tailgate and
KEYLESS-GO*, you can close the tailgate
and lock the vehicle simultaneously from
the outside using the KEYLESS-GO*
locking/closing switch.
If the tailgate comes into contact with an
object while closing (e.g. luggage that has
been piled too high), the closing procedure
is stopped and the tailgate reopens.
Make sure you have the SmartKey with
KEYLESS-GO* with you.1KEYLESS-GO* locking/closing switch

switch1 briefly.
The tailgate closes automatically. Once
the tailgate is closed, the vehicle locks
if doors are closed. The turn signals
flash three times to confirm locking.

armed.
iDo not place the SmartKey or SmartKey with
KEYLESS-GO* in the open cargo compartment.
You may lock yourself out.
iIf the vehicle was previously centrally
locked, the tailgate will lock automatically after
closing it. The turn signals will flash three times
to confirm locking.

iIf you drive in countries where vehicles drive
on the other side of the road than the country in
which the vehicle is registered, you must have
the headlamps modified for symmetrical low
beams. Relevant information can be obtained at
any authorized Mercedes-Benz Light Truck
Center.
iVehicles equipped with active Bi-Xenon*
headlamps:
The active Bi-Xenon* headlamps monitor the
vehicles steering angle and vehicle speed, then
automatically shift their beams to either side to
better follow the curvature of the road ahead,
increasing usable illumination over conventional
headlamps.1‚Standing lamps, left (turn left two

If you are driving too fast while using
off-road level 3, you will see the following
message in the multifunction display:

Reduce speed to
under 20 MPH
(30 km/h)
Additional an acoustic signal sounds.
Only use the off-road levels when neces-
sary.
Otherwise:

may be unfavorable
Start the engine (page 41).
Turn outer adjustment ring1
(
page 283) repeatedly until indicator
lamp3 (

level flashes.

Off-road level 1, lower indicator
lamp flashes

Off-road level 2, lower and middle
indicator lamps flashes

Off-road level 3, lower, middle and
upper indicator lamps flashes
The vehicle adjusts to the correspond-
ing off-road level.
For example, the following message
appears in the multifunction display while
the level is being set:
The vehicle is raised from off-road level 1
to off-road level 2.When the off-road level 2 is reached, the
following message appears in the multi-
function display for 5 seconds:
The lower and middle indicator lamps3
(

While the vehicle is adjusting from off-road
level 2 to off-road level 3, you will see, for

Driving systems
The Parktronic system deactivates at
vehicle speeds exceeding approximately
11 mph (18 km/h). At lower vehicle
speeds the Parktronic system turns on
again.
The Parktronic system also deactivates
when you set the automatic transmission
to positionP or depress the parking brake
pedal.
The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumperRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damaging the sensors, see
“Cleaning the Parktronic* system sensors”
(
page 430).
!During parking maneuvers, pay special
attention to objects located above or below the
height of the sensors (e.g. planters or trailer
hitches). The Parktronic system will not detect
such objects at close range and damage to your
vehicle or the object may result.
Ultrasonic signals from outside sources (e.g.
working jackhammers, car wash or the air brakes
of trucks) may impair the operation of the
Parktronic system.

Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when indicator lamp1
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 end of the hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to 12 cm) away from the signal
transmitter button (2, 3 or4) to be
programmed, while keeping the indica-
tor 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 re-
leased.
iIndicator lamp1 flashes immediately 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 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.

Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
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 follow-
ing two steps.
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 pro-
cess.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
complete the training process.
