The Parktronic system is activated
automatically when
Ryou switch on the ignition
and
Ryou release the parking brake
and
Rthe automatic transmission is in drive
position D, reverse gear R, or neutral
position N
The Parktronic system deactivates at speeds
above approximately 11 mph (18 km/h). At
lower speeds, the Parktronic system
activates again.
The Parktronic system also deactivates when
you shift the automatic transmission into
park position P or engage the parking brake.
The Parktronic system monitors the
surroundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
Example illustration, sensors in the front bumper
To function properly, sensors : must be free
of dirt, ice, snow and slush. Clean
sensors : regularly. Be careful not to
scratch or damage sensors :, see “Cleaning
the driving systems sensors” (Y page 263).
GWarning!
The 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
remains with the driver.
GWarning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
! 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.
During parking maneuvers, pay special
attention to objects located above or below
the height of the sensors (e.g. street curbs,
painted posts, or trailer hitches etc.). The
Parktronic system will not detect such
objects at close range and damage to your
vehicle or the object may result.
! Ultrasonic signals from outside sources
(e.g. truck air brakes, car wash, or
jackhammers) may impair the operation of
the Parktronic system.

Parktronic system malfunction
There is a malfunction in the Parktronic
system, if only the red distance segments
illuminate and an acoustic warning sounds.
The Parktronic system will switch off
automatically after 20 seconds and indicator

XHave the Parktronic system checked at an
authorized Mercedes-Benz Center as soon
as possible.
If only the red distance segments illuminate
and no acoustic warning sounds, the
Parktronic system sensors are dirty (e.g. dirt,
ice, snow and slush). Another cause could be
interference from other radio or ultrasonic
signals (e.g. truck air brakes, car wash, or
jackhammers). The Parktronic system will
switch off automatically after 20 seconds and

Parking Guidance
The Parking Guidance is part of the Parktronic
system. With the Parktronic system switched
on (Y page 168), the Parking Guidance is also
available.
The Parking Guidance is an electronic parking
aid equipped with ultrasonic sensors. The
ultrasonic 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.

GWarning!
The 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 Parking Guidance scans for and measures
potential parking spaces when driving past.
Subsequent changes to the parking space are
not taken into account. This may be the case
if the position of the vehicle parked in front or
behind the space changes or obstacles in the
parking space are moved.
The Parking Guidance does not relieve you of
the responsibility to pay attention. If you only
rely on the 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.
GWarning!
The system cannot detect objects located
above the area that the sensors scan. These
objects, e.g. protruding load, overhang, or
truck tail lifts, will be ignored when computing
the parking procedure. The Parking Guidance
might therefore provide untimely steering
instructions. This could cause a collision.
Thus, do not use the Parking Guidance in such
situations.
GWarning!
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.
Use the Parking Guidance for parking spaces
that are
R parallel to the direction of travel
R located on straight streets, i.e. not in
curves
R on the same level as the street, i.e. not on
sidewalks, for example.
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 Parktronic system
warning indicator ( Y page 167) while the
Parking Guidance is active.
R You may not use the Parking Guidance
when transporting cargo that protrudes the
vehicle.
R Do not use the Parking Guidance when
driving with snow chains or when a spare
wheel is mounted.
R How well your vehicle will be parked after
completion of the 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 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 Parking
Guidance and correct the vehicle position
yourself.
Detecting a parking space
