and remove the SmartKey from the starter
switch with the automatic transmission in a posi-
tion other than P, the transmission will automat-
ically shift toP.
Keep in mind that turning off the engine with the

Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warning/
indicator lamps, malfunction/warning mes-
sages or the failure of any systems. Driving
characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
Mercedes-Benz Center as soon as possible.i
The instrument cluster illumination is
dimmed or brightened automatically to suit am-
bient light conditions.
The instrument cluster illumination will also be
adjusted automatically when you switch on the
vehicle’s exterior lamps.
Warning!
G


Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.

Driving systems
Parktronic system*
Parktronic is an electronic parking aid with
ultrasonic sensors that helps you while
parking.
It visually and audibly indicates the relative
distance between the vehicle and an ob-
stacle.
Parktronic is automatically activated when
you switch on the ignition, release the
electric parking brake or start the engine
and engage gear D, R or N.The Parktronic system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
Parktronic is also switched off when you
engage gear P or secure the vehicle in
place with the electric parking brake and
switch off the engine.
The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumper (Only visi-
ble without DISTRONIC Plus*)Warning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice, see
“Cleaning the Parktronic* system sensors”
(page 538).
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.i
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash, or the
air brakes of trucks) can cause the system to
send erratic indications, and should be taken
into consideration.

Parktronic system malfunction
If only the red distance segments illumi-
nate and an acoustic warning sounds,
there is a malfunction in the Parktronic
system. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.

Have the Parktronic system checked
by an authorized Mercedes-Benz Cen-
ter as soon as possible.
If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty or
there is an interference from other radio or
ultrasonic signals. The Parktronic system
will automatically switch off after 20 sec-
onds and the indicator lamp in the Park-
tronic switch comes on.

ence from outside radio or ultrasonic
signals.

412 Controls in detailDriving systemsCollision warning
Park Assist can detect obstacles from a
considerable distance. If you drive in re-
verse towards an obstacle, you will hear a
warning tone. You must then brake in or-
der to avoid a collision. The warning tone
for a collision will not sound when the vehi-
cle is at a standstill very close to the obsta-
cle. In this case, you will hear a
corresponding tone for the warning indica-
tor in the rear area.Switching Park Assist system on/off
The Park Assist system can be switched off
manually.
The Park Assist button with the indicator
lamp is located on the control panel on the
right-hand side of the instrument cluster.

Switch on COMAND (
page 79).

Move gear selector lever to position R
(reverse gear).
The COMAND display will show the
area behind the vehicle with guide lines
to help you reverse into a parking
place.
Reverse parking (back-in parking)This function helps you when you are re-
versing in a straight line or backing in at
any angle.
The space required by the vehicle for re-
versing is shown by guide lines.
When you turn the steering wheel to a
straight-ahead position, you will see the
guide lines on the COMAND display in the
following order:
1Yellow and blue guide lines for vehicle
width
2Yellow 13 ft (4 m) guide line
3Yellow 39 in (1 m) guide line
4Red 10 in (0.25 m) guide line
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 Dynamic Rear
View Monitor. Contact an authorized
Mercedes-Benz Center.Warning!
G
Use of Dynamic Rear View Monitor can be
dangerous if you are color-blind or have im-
paired color vision.
Only use Dynamic Rear View Monitor if you
can see and distinguish all colored guide
lines shown by Dynamic Rear View Monitor
on the COMAND display.i
The Dynamic Rear View Monitor must be ac-
tivated in the instrument cluster control system
in order for it to be switched on (
page 253).
i
If you activate a different function on the
driver’s COMAND controls while reverse parking
or parallel parking, the image from the back-up
camera is interrupted.
To reactivate the camera, take the vehicle out of
reverse gear and then re-engage reverse gear
again.

The desired parking space is wide
enough if nothing is inside the yellow
and blue guide lines1 of your intend-
ed driving path or protrudes into this
area.

Back in straight carefully.
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.
