The exterior lamp switch is located on the
dashboard to the left of the steering wheel.

If 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 Center.
i
The active Bi-Xenon headlamps monitor
your steering angle and driving speed, then auto-
matically shift their beams to either side to bet-
ter follow the curvature of the road ahead,
increasing usable illumination over conventional
headlamps.

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:

Cruise control (
page 437) and
DISTRONIC Plus*(page 443), with
which the vehicle can maintain a preset
speed.


ABC (
page 461) adjusts the vehicle
suspension characteristics automati-
cally and control the vehicle level.


Parktronic* (
page 463), Park Assist*
(
page 467) and Advanced Parking
Guidance* (
page 471), which serve
as a parking assistant.


Rear View Camera* (
page 477) are
electronic and visual parking aids.


Night View Assist* (
page 481) illumi-
nates the road with infrared light in
addition to the normal headlamps.


Blind Spot Assist* (
page 485) de-
tects and warns you about vehicles in
your blind spot.For information on the ABS, Adaptive
Brake, BAS, BAS Plus*, EBP, ESP
® and
PRE-SAFE
® Brake*, see “Driving safety
systems” (page 65).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time.
You can set or resume the cruise control at
any speed over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it
advisable to travel at a constant speed.

The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a constant speed.


The use of the cruise control can be dan-
gerous on slippery roads. Rapid changes
in tire traction can result in wheel spin
and loss of control.


Deactivate the cruise control when
driving in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Special attention must be paid to objects
outside of the camera’s field of view such as
those located very close to or below the rear
bumper, or above the recessed grip of the
luggage compartment lid. Such objects may
not be detected by the system and can dam-
age the vehicle.
The Rear View Camera does not warn you
about impending collisions with objects. The
driver is always responsible for safety and
must continue to pay attention to the imme-
diate surroundings while parking or maneu-
vering the vehicle. This applies not only to
the area behind the vehicle, but also to the
area in front of and to the sides of the vehi-
cle. Failure to do so could result in injury to
persons and/or damage to the vehicle or
other property. We also recommend that the
driver uses the Parktronic system* or Park
Assist* when parking or maneuvering the
vehicle.
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.Warning!
G
The Rear View Camera may not function if:

the trunk lid is not completely closed


it is raining or snowing heavily, or if
there is thick fog


in a very dark area


the camera is exposed to very strong
white light (white stripes may appear on
the COMAND display)


the surrounding area is lit with fluores-
cent light (the COMAND display can
flicker)


outside temperatures are very high (lens
condensation)


there is a sudden change in tempera-
ture, for example when you drive out of
the cold into a heated garage in winter
(lens condensation)


the camera lens is dirty or covered, see
“Cleaning the Rear View Camera* lens”
(page 602)


the rear of your vehicle is damaged. In
this case, have the position and setting
of the camera checked by a qualified
technician. Contact an authorized
Mercedes-Benz Center.
Do not use the Rear View Camera if the
roads are icy, slippery or covered with snow.
The vehicle could slip causing the actual ve-
hicle position to deviate from the one shown
on the COMAND display.
This may cause injury to you or others, or
damage the vehicle or objects.
Mounting tires/rims of other specification
than the original equipment tires/rims may
impair the function of the Rear View Cam-
era. Contact an authorized Mercedes-Benz
Center.

Night View Assist*Night View Assist illuminates the road with
infrared light in addition to the normal
headlamps.
A camera at the top of the windshield mea-
sures the infrared light and shows a
black-and-white image on the multifunc-
tion display.
The image on the multifunction display cor-
responds to a road lit up by high-beam
headlamps.The Night View Assist image on the multi-
function display is not impaired


by the headlamps of approaching vehi-
cles


if you cannot switch on the high beams
due to oncoming traffic
As a result, you can better follow the
course of the road and detect obstacles
earlier on.
i
If you activate a different function on the
driver’s COMAND controls while reverse parking
or parallel parking, the image from the Rear View
Camera is interrupted.
To reactivate the Rear View Camera, take the ve-
hicle out of reverse gear and then re-engage re-
verse gear again.Warning!
G
Night View Assist is only an aid to support
you while driving and cannot substitute your
careful attention. Do not rely on the display
of the Night View Assist; instead, continue
to look through the windshield. You are al-
ways responsible for safety and must drive
in accordance with traffic conditions. Other-
wise, you could endanger yourself and oth-
ers.
If it is foggy, raining or snowing, the clarity of
the Night View Assist image on the multi-
function display may be diminished.
Warning!
G
Night View Assist cannot record objects im-
mediately in front of or next to the vehicle.
When maneuvering, continue to look
through the windshield. Make sure no per-
sons or animals are in the area in which you
are maneuvering. You could otherwise in-
jure them.
i
Infrared light is invisible to the human eye
and can therefore remain permanently switched
on without blinding oncoming traffic.
