Use Active Parking Assist for parking spaces:
R
that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same
level as the road, e.g.
not on the pavement
Parking tips:
R On narrow roads, drive as close to the
parking space as possible.
R Parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 182) warning messages during the
parking procedure.
R You can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R when snow chains or an emergency spare
wheel are mounted, you should not use
Active Parking Assist here either.
R Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the
vehicle.
Detecting parking spaces Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or
loading

ramps of goods
vehicles. In some circumstances, Active
Parking Assist may therefore guide you into
the parking space too early. G
WARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely. You may cause a collision as a result. There is
a risk of an accident.
If there are objects
above

the detection range,
stop and deactivate Active Parking Assist.
Active Parking Assist is switched on
automatically when driving forwards. The
system is operational at speeds of up to
approximately 22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle. When driving at speeds below
19 mph (30 km/h), you will see the parking
symbol as a status indicator in the instrument
cluster. By default, Active Parking Assist only
displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. To park
on the driver's side, you must leave the
driver's side turn signal switched on. This
must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the 0076 button on the
multifunction steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears. Example: detected parking space
0043
Detected parking space on the left
0044 Parking symbol
0087 Detected parking space on the right
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 51 in (1.3 m) longer than
your vehicle Driving systems

the area behind your vehicle in the Audio/
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display.

To deactivate: the rear view camera is
deactivated if you:
R shift the transmission to position P
R drive forwards 33 ft (10 m)
R shift the transmission from R to another
position after 15 seconds
R drive forwards at a speed of over 5 mph
(10 km/h )
Displays in
the

Audio/COMAND display The rear view camera may show a distorted
view of obstacles, show them incorrectly or
not at all. The
rear

view camera does not show
objects in the following positions:
R very close to the rear bumper
R under the rear bumper
R in the area immediately above the tailgate
handle
! Objects not at ground level may appear to
be further away than they actually are, e.g.:
R the bumper of a parked vehicle
R the drawbar of a trailer
R the ball coupling of a trailer tow hitch
R the rear section of an HGV
R a slanted post

coupling that have been approved for this
vehicle by Mercedes-Benz. Distances may
differ if you use other

ball couplings. In this
case, take into account that actual

distance specifications. Otherwise you
could damage the trailer and vehicle. 0043

Towing a trailer
When you attach a trailer,

make sure you have
correctly established the electrical
connection. This can be accomplished by
checking the trailer lighting. Towing a trailer
Notes on towing a trailer
Important safety notes G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can

overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even
rollover. There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
! Depressing the brake pedal constantly
results

in excessive and premature wear to
the brake pads.
Please observe the manufacturer's operating
instructions for the trailer coupling if a
detachable trailer coupling is used.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
The applicable permissible values, which
must not be exceeded, can be found:
R in the vehicle documents
R on the identification plates of the trailer tow
hitch, the trailer and the vehicle
If the values differ, the lowest value applies.
You will find the values approved by the
manufacturer on the vehicle identification
plates and those for the towing vehicle under
"Technical data".
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer. 208
