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
your authorized Mercedes-Benz Center.
i
The active Bi-Xenon headlamps monitor the
vehicles steering angle, then automatically shift
their beams to either side to better follow the
curvature of the road ahead, increasing usable
illumination over conventional headlamps.

380 Controls in detailDriving systemsThe driving systems of your vehicle are de-
scribed on the following pages:

Cruise control and DISTRONIC Plus*,
with which the vehicle can maintain a
preset speed.


Distance warning function* (only avail-
able with DISTRONIC Plus*), which
warns of a stationary obstacle or slow-
er moving vehicle that you are closing
on to quickly.


Airmatic (S 550 only) and ABC* adjust
the vehicle suspension characteristics
automatically and control the vehicle
level.


Parktronic* and Park Assist*, which
serve as a parking assistant.


Dynamic Rear View Monitor* is an
electronic and visual parking aid.


Night View Assist* illuminates the road
with infrared light in addition to the nor-
mal headlamps.For information on the ABS, Adaptive
Brake, BAS, BAS Plus*, EBP, and ESP
® driv-
ing systems, see “Driving safety systems”
(
page 69).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
The use of cruise control is recommended
for driving at a constant speed for extend-
ed periods of time. You can set or resume
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
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. 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 steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


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


Deactivate 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.

G
The Dynamic Rear View Monitor is a supple-
ment system. It is not intended to, nor does
it replace, the need for extreme care. The re-
sponsibility during parking and other driving
maneuvers always rests with the driver.
The Dynamic Rear View Monitor may show
obstacles with a distorted perspective, in-
correctly or not at all.
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 Dynamic Rear View Monitor does not
warn you about impending collisions with
objects. The driver is always responsible for
safety and must continue to pay attention to
the immediate surroundings while parking
or maneuvering 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
vehicle. 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 use the Parktronic system* or Park
Assist* when parking or maneuvering the
vehicle.Warning!
G
Make sure that no persons or animals are
standing in the area where you are maneu-
vering. You could otherwise injure them.Warning!
G
The Dynamic Rear View Monitor 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)


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)


outside temperatures are very high (lens
condensation)


the camera lens is dirty or covered, see
“Cleaning of the Dynamic Rear View
Monitor lens*” (
page 538)


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 Dynamic Rear View Monitor
if the roads are icy, slippery or covered with
snow. The vehicle could slip causing the ac-
tual vehicle position to deviate from the one
shown on the COMAND display.

Replacing bulbs
Replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies 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 ad-
justment.
i
If the headlamps or front fog lamps are
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.
i
Substitute bulbs will be brought into use
when the following lamps malfunction:


Brake lamps


Rear fog lamps


Front parking lamps


Tail lamps


Turn signal lamps
Observe the messages in the multifunction dis-
play (page 557).

623 Practical hints
Replacing bulbs
Notes on bulb replacement


Only use 12-volt-bulbs of the same
type and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center.


the Bi-Xenon lamps


the front turn signal lamps


the front fog lamps


the additional turn signal lamps in the
exterior rear view mirrors


the parking and standing lamps


the front side marker lamps


the high mounted brake lamps


the brake, tail and rear standing lamps


the rear side marker lamps


the rear fog lamp


the rear turn signal lamps

Replacing bulbs for front lamps
Before you start to replace a bulb for a
front lamp, do the following first:
Turn the exterior lamp switch to M
(page 342).

Open the hood (
page 492) (except
for side marker lamps).
Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
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.
i
Have the headlamp adjustment checked
regularly.
