i During strong rainfall, the warning
indicators and warning tones may be
triggered, for example, by water splashing
into the area of the sensors.
Collision warning The Park Assist can detect obstacles from a
considerable distance. If you drive in reverse
towards an obstacle, you will hear a warning
tone. You must then brake in order to avoid a
collision. The warning tone for a collision will
not sound when the vehicle is at a standstill
very close to the obstacle. In this case, you
will hear a corresponding tone for the warning
indicator in the rear area.

The Advanced Parking Guidance is an
electronic parking aid equipped with radar
sensors. The radar sensors scan the area on
both sides of vehicle. When a suitable parking
space is found, it is indicated by a parking
space symbol in the multifunction display.
You will receive steering instructions for
parking in that space. G
Warning!
The Advanced Parking Guidance is only an aid
and may display parking spaces that are not
suitable for parking such as
R no-parking zones
R parking space with unsuitable road/ground
surface
R driveways
R entrances/exits
The Advanced Parking Guidance only shows a
representation of the parking space in the
multifunction display as parking space is first Driving systems

initially measured when driving past.
Subsequent
changes
to the parking space are
not taken into account, e.g. if the position of
the vehicle parked in front of or behind the
space changes or objects in the parking space
are moved. Moving objects are not shown,
e.g. pedestrians or vehicles driving past. The
Advanced Parking Guidance does not relieve
you of the responsibility to pay attention. If
you only rely on the Advanced Parking
Guidance, you may cause an accident and
injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering. G
Warning!
Make sure no persons or animals are in the
area in

which you are maneuvering. You could
otherwise injure them.
! Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts,
elevated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
! The operation and functionality of the
Advanced Parking Guidance can be
affected or impaired by dirty sensors,
especially at times of snow and ice.
Make sure that the area on the bumpers
around the sensors is free of dirt, ice and/
or slush, otherwise Advanced Parking
Guidance may not function properly.

Parking instructions:
R
On narrow streets, drive by the parking
space as close as possible.
R Parking spaces that are dirty, overgrown or
located in front of trailers may not be
detected correctly.
R Snowfall or heavy rain may cause imprecise
measurement of the parking space.
R Also observe the Park Assist warning
indicator ( Y page 326) while the Advanced
Parking Guidance is active.
R How well your vehicle will be parked after
completion of the Advanced Parking
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 immediate surroundings.
In certain cases, the Advanced Parking
Guidance may guide you too far into the
parking space or not far enough. If this is
the case, cancel the parking procedure
with the Advanced Parking Guidance and
correct the vehicle position yourself.
Detecting a parking space The Advanced Parking Guidance is active
when driving forward. The system operates at
a vehicle speed of up to 25 mph (40 km/h).
It scans automatically for and measures
potential parking spaces on both sides of the
vehicle. :
Detected parking space on the left
; Parking space symbol
= Detected parking space on the right
At a vehicle speed of below 10 mph
(16 km/h), you see white parking space
symbol ; as a system display in the
multifunction display. As soon as the
Advanced Parking Guidance has detected a
suitable parking space, parking space
symbol ; changes to blue.
When a parking space has been detected, an
additional arrow to the right = or to the
left : appears.
In order to be detected by the Advanced
Parking Guidance, a parking space must be
R closed-in at the rear
R parallel to the direction of travel
R at least 5 ft (1.5 m) wide
R at least 3.5 ft (1.0 m) longer than your
vehicle is
A parking space is shown in the multifunction
display when driving by until you have
reached a distance of 50 ft (15 m) from the
space. The Advanced Parking Guidance only
shows parking spaces on the 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 the reverse gear is engaged. Driving systems

the responsibility to be cautious. Take care
and pay careful attention. The rear view
camera may not show objects which are
R very close to the rear bumper
R under the rear bumper
R above the trunk handle You are responsible for safety at all times and
must continue to pay attention to the
immediate surroundings when parking and
maneuvering. This includes the area behind,
in front of, and beside the vehicle. Otherwise
you could endanger yourself and/or others.
G
Warning!
The rear view camera either will not function
or will not function to its full capability if
R the trunk lid is open
R it is raining very hard, snowing or foggy
R it is night or you are parking/maneuvering
your vehicle

in an area where it is very dark
R the camera is exposed to a very bright white
light
R the immediate surroundings are
illuminated with fluorescent light (the
COMAND system display can flicker)
R there is a sudden change in temperature,
e.g. if you drive into a heated garage from
the cold (lens condensation)
R the camera lens is dirty or covered
R the rear of your vehicle is damaged
In this case, have the position and setting
of the camera checked by a qualified
specialist workshop. Mercedes-Benz
recommends that you contact a Mercedes-
Benz Center for this purpose.
Do not use the rear view camera in these
situations. Otherwise you could injure
yourself or others and/or damage property
including your vehicle while parking/
maneuvering. G
Warning!
Use of rear view camera can be dangerous if
you are color-blind or have impaired color
vision.

Warning!
Please note that objects which do not touch
the ground may appear to be further away
than they actually are, for example:
R the bumper of a vehicle parked behind you
R a trailer hitch
R the back of a truck
In such cases, you should not use the
guidelines to judge the distance. You may
misjudge the distance which increases the
risk of impacting the objects.
Even when the object you approach is directly
on the ground do not approach the object any
closer than the red guideline. Red guideline
= indicates an approximate
distance of 10 in (0.25 m) from the rear of the
vehicle. Yellow guidelines ; indicate an
approximate distance of 3 ft (1 m) from the
rear of the vehicle. Blue guidelines :
indicate the approximate width required for

A camera at the top of the windshield
measures the infrared light and shows a
black-and-white image in the multifunction
display. The image in the multifunction
display corresponds to a road lit up by high-
beam headlamps. G
