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.

Front area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approximately two sec-
onds. Once the second red segment
lights up, you will hear a continuous
warning tone. You have reached the
minimum distance.


Rear area:
As soon as the first red segment lights
up, you will hear an intermittent warn-
ing tone for approximately two sec-
onds. Once the second red segment
lights up, you will hear a continuous
warning tone. You have reached the
minimum distance.Collision 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.

Advanced Parking Guidance*
Advanced Parking Guidance is an electron-
ic parking aid equipped with radar sensors
that scan the area on both sides of vehicle.
When suitable parking space is found it is
shown in the display and you receive steer-
ing instructions for parking in that space.
i
The Park Assist system is automatically
switched on when the ignition (
page 370) and
radar sensors are switched on (page 307).
Warning!
G
Advanced Parking Guidance is only an aid
and may display parking spaces that are not
suitable e.g. due to parking regulations, un-
suitable road/ground surfaces, driveways,
entrances/exits, etc.
Advanced Parking Guidance only shows a
representation of the parking space in the
instrument cluster display as parking space
is first initially measured when driving past.
Subsequent changes to the parking space
are not taken into account, e.g. if the posi-
tion of the vehicle parked in front of or be-
hind the space changes or objects in the
parking space are moved. Moving objects
are not shown, e.g. pedestrians or vehicles
driving past. Advanced Parking Guidance
does not relieve you of the responsibility to
pay attention. If you only rely on Advanced
Parking Guidance, you may cause an acci-
dent and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your im-
mediate surroundings when parking and
maneuvering.

How well your vehicle will be parked af-
ter completion of the Advanced Park-
ing Guidance depends on the position
and shape of the vehicles parked in
front of and behind the parking space
as well as the conditions of the imme-
diate surroundings. In certain cases,
Advanced Parking Guidance may guide
you too far into the parking space or
not far enough. If this is the case, can-
cel the parking procedure with Ad-
vanced Parking Guidance and correct
the vehicle position yourself.Detecting a parking space
Advanced Parking Guidance is active when
driving forward. The system operates at a
vehicle speed of up to 25 mph (40 km/h)
and automatically scans for and measures
potential parking spaces on both sides of
the vehicle. At a vehicle speed of below
10 mph (16 km/h), you see the white
parking space symbol as a system display
in the instrument cluster. As soon as Ad-
vanced Parking Guidance has detected a
suitable parking space, the parking space
symbol changes to blue.
Detected parking space1Detected parking spaces on the left
2Parking space symbol
3Detected parking spaces on the right
In order to be detected by Advanced Park-
ing Guidance, a parking space must be:

closed-in at the rear


parallel to the direction of travel


at least 5 ft (1.5 m) wide


at least 3.5 ft (1.0 m) longer than your
vehicle

484 Controls in detailDriving systemsA parking space is shown in the display
when driving by until you have reached a
distance of 50 ft (15 m) from the space.
Advanced Parking Guidance only shows
parking spaces on the front-passenger
side of the vehicle unless you activate the
driver's side (left) turn signal. If you would
like to park on the driver's side, the left
turn signal must remain on until reverse
gear is engaged.Parking
The following describes how you can park
on the front-passenger side. Parking on
the driver's side is performed reversed left
to right.
If Advanced Parking Guidance detects an
obstacle behind the vehicle during the
parking procedure, you will hear an audible
warning. Stop the vehicle immediately. The
parking space and the lane blink in the in-
strument cluster. Only continue driv-
ing/parking after you have made sure that
this is possible to do in a safe manner. If
Advanced Parking Guidance no longer de-
tects any obstacles, the display in the in-
strument cluster stops blinking. You may
continue the parking procedure.

Bring the vehicle to a standstill as long
as the desired parking space is dis-
played by the blue parking space sym-
bol in the instrument cluster.

Shift the automatic transmission to
positionR.
The message “Check Surroundings
Press 'OK' to Confirm” appears in the
multifunction display.Warning!
G
Advanced Parking Guidance is only an aid
and may not detect all obstacles. At corners
or near smooth surfaces, Advanced Parking
Guidance may not detect an object correct-
ly. Advanced Parking Guidance does not re-
lieve you of the responsibility to pay
attention. You are always responsible for
safety and must continue to pay attention to
your immediate surroundings when parking
and maneuvering. Otherwise, you could en-
danger yourself and others.

The Rear View Camera 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)


outside temperatures are very high (lens
condensation)


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)


the camera lens is dirty or covered, see
“Cleaning the Rear View Camera* lens”
(page 621)


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 Rear View Camera if the
roads are icy, slippery or covered with snow.
The vehicle could slip causing the actual ve-
hicle position to deviate from the one shown
on the COMAND display.
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 Rear View Cam-
era. Contact an authorized Mercedes-Benz
Center.
Warning!
G
Use of Rear View Camera can be dangerous
if you are color-blind or have impaired color
vision.
Only use Rear View Camera if you can see
and distinguish all colored guide lines shown
by Rear View Camera on the COMAND dis-
play.i
The Rear View Camera must be activated in
the instrument cluster control system in order
for it to be switched on (
