486 Controls in detailDriving systemsSensor monitoring range
Blind Spot Assist is able to monitor a range
up to three meters to the rear and both
sides of the vehicle.
The Blind Spot Assist sensors are built into
t h e f r o n t a n d r e a r b u m p e r s . M a k e s u r e t h a t
the area of the bumpers around the sen-
sors is free of dirt, ice and snow. The radar
sensors must not be obstructed, for exam-
ple, by bicycle carriers or overhanging lug-
gage.
Warning!
G
Blind Spot Assist monitors certain areas in
the immediate vicinity of your vehicle. Vehi-
cles approaching and passing at increased
speeds will not be detected. There will be no
warning display and no audible warning.
When driving in a very wide lane, the sensors
may not be able to cover the entire width of
the neighboring lane. Vehicles driving on the
outside of the neighboring lane may not be
detected.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.
When driving in a very narrow lane, the sen-
sors may detect and display vehicles in the
second lane over. This will be the case if
there are vehicles driving on the inside edge
of their lane.!
In the event of a significant impact or dam-
age affecting the bumpers, have the radar sen-
sors checked by a qualified specialist workshop
such as a Mercedes-Benz Center. Failure to do
so can result in Blind Spot Assist not functioning
correctly.

Indicator and warning lamps
1Yellow indicator lamp/red warning
lamp
Switching on: Make sure that the ra-
dar sensors (
page 302) and the Blind
Spot Assist (page 299) are switched
on.
With the ignition switched on, the warn-
ing lamp1 in the exterior mirror lights
up red.
With the engine running, the indicator
lamp1 in the exterior mirror lights up
yellow up to a speed of 20 mph
(30 km/h).Once a speed above 20 mph (30 km/h)
has been reached and


Blind Spot Assist detects no vehicle in
its range, the indicator lamp1 goes
out


Blind Spot Assist detects another vehi-
cle in its range, the warning lamp1 on
the corresponding side of the vehicle
turns red.Collision warning
If a vehicle is detected in the Blind Spot As-
sist range and you activate the turn signal,
a two-tone warning will sound and the red
warning lamp1 will flash.

Remain on the lane that you are cur-
rently on until traffic conditions permit
to change.
If the turn signal remains on, the red warn-
ing lamp1 will flash to indicate that vehi-
cles have been detected. No further
audible warnings will sound.
Warning!
G
Blind Spot Assist is not active at speeds be-
low approximately 20 mph (30 km/h). You
will not be alerted to the presence of vehi-
cles in the monitored area at these speeds.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle. Failure to do so could
result in recognizing dangers too late, possi-
bly resulting in an accident and serious inju-
ry to yourself and others.
Warning!
G
Do not change lanes or make turns, while
the red warning lamp
1
is flashing. Doing
so could result in an accident and seroius in-
jury to yourself and others.

rately adjust the air temperature on each
side of the passenger compartment. You
should raise or lower the temperature set-
ting in small increments, preferably start-
ing at 72°F (22°C). The automatic climate
control will adjust to the set temperature
as fast as possible.

You can use this setting to defrost the
windshield, for example if it is iced up. You
can also defog the windshield and the side
windows.i
Keep this setting selected only until the
windshield is clear again.

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 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 272) is activated, or
press button;.

low 41°F (5°C), the air recirculation mode will
not switch on automatically.
i
The manually selected air recirculation
mode is deactivated automatically:


after 5 minutes if the outside temperature is
below approximately 41°F (5°C)


after 5 minutes if the air conditioning is
turned off


after 30 minutes if the outside temperature
is above approximately 41°F (5°C)
Warning!
G
Never operate the side windows and the
tilt/sliding sunroof if there is the possibility
of anyone being harmed by the closing pro-
cedure.
When using the air recirculation mode with
convenience closing feature, should the up-
ward movement of a window be blocked by
some obstruction including but not limited
to arms, hands, fingers, etc., the automatic
reversal feature will not operate.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by pressing
the respective window switch. The closing of
the tilt/sliding sunroof can be immediately
halted by moving the tilt/sliding sunroof
switch in the overhead control panel in any
direction.

A window or tilt/sliding sunroof that has been
moved will remain in its current position if
button, is used to reopen the remaining
windows or tilt/sliding sunroof.

Trunk opening-height restriction
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 268).

1Handle

Lower trunk lid by pulling firmly on
handle1.

Close the trunk with hands placed flat
on the trunk lid.
The power closing assist automatically en-
sures that the trunk lid is pulled closed
completely (
page 363).
i
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.
The vehicle is only locked when the turn signals
flash three times. If you are carrying a second SmartKey with KEYLESS-GO* with you, you can
still lock the vehicle.
Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the trunk
lid opening when closing the trunk. Be espe-
cially careful when small children are
around.
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.

vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.
i
If the trunk lid comes into contact with an
object while closing (e.g. luggage that has been
piled too high) in the upper motion sequence, the
closing procedure is stopped and the trunk re-
opens slightly.
