Warning!
G
Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance as the use of the guide lines to judge
distance increases the risk of impacting the
objects.
Even when the object you approach is di-
rectly on the ground (and nothing on the ob-
ject extends above the ground beyond the
object's contours directly touching the
ground) and no objects that do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck are in the path, do not ap-
proach the object on the ground any closer
than red guide line4.

lel to the road.

another vehicle is located next to you,
the extended blue guide line4 must
just touch the corresponding vertical
blue guide line1.
Warning!
G
If the respective vertical guide line1 is not
yet located at the end of the parked vehicle
and you are already turning into the parking
space, you could collide with the parked ve-
hicle. Stop the parking procedure immedi-
ately. Pull out of the parking space and start
the parking procedure over again.
i
If an obstacle is inside of or protrudes into
the area marked by blue guide lines4 for the
vehicle, the parking space is too small for the ve-
hicle.

If you turn the steering wheel too far, the
message “Steering wheel turned too far. Please
adjust steering wheel” appears on the COMAND
display. Turn the steering wheel back until the

abled.”. Pull out of the parking space and start

420 Controls in detailDriving systemsNight 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.
The camera is at the top of the windshield.

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 that no
persons or animals are in or near the area in
which you are maneuvering.
i
Infrared light is invisible to the human eye
and can therefore remain permanently switched
on without blinding oncoming traffic.

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).
!
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.
