Driving systems
The Parktronic system deactivates at
speeds exceeding approximately
11 mph (18 km/h). At lower vehicle
speeds the Parktronic system turns on
again. The Parktronic system also deacti-
vates when you place the gear selector le-
ver in position P 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 sensorsFront sensors
Rear sensorsiTo function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to scratch or
damage the sensors, see “Cleaning the
Parktronic system* sensors” (
page 337).

!During parking maneuvers, pay special at-
tention 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.
truck air brakes, car wash, or jackhammers) may
impair the operation of the Parktronic system.

Step 2:
If you have previously programmed an
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 the end of 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 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 re-
leased.
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.

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 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 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.
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.

Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a use 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 Distronic* system sensor

Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water and a
non-scratching cloth to clean sensor
cover1.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 337). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may
vibrate.
!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 damp
cloth to clean those ornamental moldings.
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 clean-
ing solutions which are not suitable may damage
the plastic lamp lenses of the headlamps. There-
fore, 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.

On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may
appear in the multifunction display.
For your convenience the messages are
divided into two sections:
Text messages (page 361)
Symbol messages (page 376)
Warning!G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative. Contact your nearest
authorized Mercedes-Benz Center.
As a result, you will not be able to see
information about your driving conditions,
such as speed or outside temperature,
warning/indicator lamps,
malfunction/warning messages or the fail-
ure of any systems. Driving characteristics
may be impaired.
If you must continue to drive, do so with
added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.
iSwitching on the ignition causes all instru-
ment cluster lamps (except high beam headlamp
indicator lamp and turn signal indicator lamps
unless activated) as well as the multifunction dis-
play to come on. Make sure the lamps and the
multifunction display are in working order before
starting your journey.

Replacing bulbs
Replacing bulbs
Bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp
assemblies are in good working order at
all times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Center for headlamp
adjustment.
Warning!G
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before chang-
ing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas.
A bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of high
humidity, driving the vehicle a distance with
the lights on should clear up the fogging.
iAuxiliary bulbs will be brought into use when
the following lamps malfunction:
Turn signal lamps
Brake lamps
Parking lamps
Tail lamps
Observe the messages in the multifunction
display (
