Driving systems
Front sensors
Rear sensorsWarning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle.
The warning indicator for the front area is
in the instrument cluster. The warning indi-
cator for the rear area is on the roof liner in
the rear.
1Left side of the vehicle
2Right side of the vehicle
3Indicator
Each warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle.
If yellow indicators 3 under the segments
are lit, Park Assist is ready to measure.The position of the gear selector lever de-
termines which warning indicators will be
activated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sev-
enth distance segment illuminates, you
have reached the minimum distance.i
Due to the sensors’ broad detection range,
it is possible that Park Assist also detects the fol-
lowing obstacles and issues a warning:


obstacles in the ground, e.g. sewer canal
covers, rails, bumps in the road or gutters


obstacles moving upward quickly, e.g. rolling
garage doors

!
While parking, pay particular attention to ob-
jects over or underneath the sensors, e.g. flower
boxes, an elevated crossbar or a trailer tow
hitch. Park Assist does not detect such nearby
objects. You could otherwise damage the vehicle
or the objects.

502 Controls in detailAutomatic climate controlThe automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
It can only function optimally when you are
driving with the windows and the tilt/slid-
ing sunroof/panorama sunroof* closed.
It is possible to completely deactivate the
climate control system (
page 503). Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
i
If you have the air distribution and air vol-
ume automatically controlled, you can adjust the
temperature, footwell temperature and air flow.
The following basic settings are recommended:


Automatic air distribution control
(page 501)


Temperature: 72°F (22°C) (
page 504)


Footwell temperature: 0 (
page 278)


Air flow: focused (
page 279)
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pages
and in the “COMAND automatic climate
control” section (
page 273). Otherwise
the windows could fog up, impairing visibili-
ty and endangering you and others.
Warning!
G
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A
clogged filter will reduce the air volume to
the interior and the windows could fog up,
impairing visibility and endangering you and
others. Have a clogged filter replaced as
soon as possible at an authorized
Mercedes-Benz Center.i
If the vehicle interior is hot, ventilate the in-
terior before driving off, see “Summer opening
feature” (
page 412). The automatic climate
control will then adjust the interior temperature
to the set value much faster.
Keep the air intake grille in front of the wind-
shield free of snow, leaves, sticks, and any other
debris.

Maximum cooling MAXCOOL (USA only)
If U is selected on both the left and
right side and there is a high demand for
cooling, the display “MAXCOOL” appears
in the COMAND display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof or tilt/sliding panel*
are closed).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving in a
tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
!
The rear window defroster uses a large
amount of power. To keep battery drain to a min-
imum, switch off the defroster as soon as the
rear window is clear.
i
The defroster is automatically deactivated
after some time of operation depending on the
outside temperature.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.i
If the rear window defroster switches off too
soon and the indicator lamp goes out, this indi-
cates that too many electrical consumers are op-
erating simultaneously and the load on the
battery is reducing available voltage. The system
responds automatically by deactivating the rear
window defroster.
i
Maximum cooling MAXCOOL is only avail-
able when the engine is running.Warning!
G
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air
conditioning (
page 276) is activated, or
press button;.

To interrupt the opening procedure:

Release switch1.Trunk opening-height restriction*
Vehicles with trunk opening/closing sys-
tem*:
The trunk lid opening height can be limited
when transporting goods on a roof rack
(e.g. presence of an optional MB sport lug-
gage container). When activated, the trunk
opens to approximately the height of the
roof edge.

Activate the limiting opening height of
trunk lid using the COMAND system
(page 272).
Closing trunki
Do not place the SmartKey in the open
trunk. You may lock yourself out.
i
If the vehicle was previously centrally
locked, the trunk will lock automatically after
closing it. All turn signal lamps flash three times
to confirm locking.
Vehicles with KEYLESS-GO*: To prevent a possi-
ble inadvertent lockout, the trunk will open auto-
matically if a SmartKey with KEYLESS-GO* is
recognized inside the vehicle or in the trunk.

G
When closing the tilt/sliding sunroof, make
sure that there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof encounters an ob-
struction that blocks its path in a circum-
stance where you are closing the tilt/sliding
sunroof by moving the tilt/sliding sunroof
switch past the resistance point, or by
pressing and holding button‹on the
SmartKey, by pressing and holding the sen-
sor surface (vehicles with KEYLESS-GO*) on
the outside door handle, the automatic re-
versal function will not operate.
The opening/closing procedure of the
tilt/sliding sunroof can be immediately halt-
ed by releasing the switch or, if the switch
was moved past the resistance point and re-
leased, by moving the switch in any direc-
tion.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.!
To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
!
Please keep in mind that weather conditions
can sometimes change rapidly. Make sure to
close the tilt/sliding sunroof when leaving the
vehicle. If water enters the vehicle interior, vehi-
cle electronics could be damaged which is not
covered by the Mercedes-Benz Limited
Warranty.
i
When the tilt/sliding sunroof is open, reso-
nance noises may result in addition to the usual
wind noises. They are caused by minimal pres-
sure changes in the passenger compartment. To
reduce or eliminate these noises, change the po-
sition of the tilt/sliding sunroof or open a side
window slightly.
i
You can also open or close the tilt/sliding
sunroof using the SmartKey, see “Summer open-
ing feature” (
page 412) and “Convenience
closing feature” (page 413). Depending on
current position, the tilt/sliding sunroof may
also open or close when the air recirculation
button, (
page 501) is pressed and held
for 2 seconds.
