Important safety notes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitable parking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 185). G
WARNING
Parking Guidance is merely an aid and may
recommendp arking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited, drive-
ways, unsuitable surfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring.
G
WARNING
Objectsl ocated above the height range of
Parking Guidance will not be detected when
the parking space is measured. These are not
taken into account when the parking proce-
dure is calculated, e.g. overhanging loads, tail
sections or loading ramps of goods vehicles.

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
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section. G
WARNING
If the Check trailer hitch locking mechanism message appears in the multi-
function display while the vehicle is in motion,
pull over immediately and check whether the
ball coupling is correctly engaged. G
WARNING
Always observe the maximum speed permit-
ted in Germany for vehicle/trailer combina-
tions, even in countries where higher speeds
are permitted. This lowers the risk of an acci-
dent. G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
WARNING
On no account should you attempt to draw the
vehicle/trailer combination out by increasing
speed. General information i
When towing atrailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for am aximum load; see the tyre pressure
table in the fuel filler flap (Y page 321).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 343).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
and trailer identification plates. The lowest
weight applies.
! Use anoseweight as close as possible to
the maximum permissible noseweight. Do
not use anoseweight of less than 50 kg,
otherwise the trailer may come loose.
Bear in mind that the payload and the rear
axle load are reduced by the actual nose-
weight.
Please note that when towing atrailer, PARK-
TRONIC (Y page 185) and parking guidance
(Y page 189) are only available with limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer with aheight-adjustable draw-
bar.
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 65).
In Germany, the maximum permissible speed
for vehicle/trailer combinations depends on
the type of trailer, and is either 80 km/h or
100 km/h. In some countries, higher maxi-
mum speeds are permissible for vehicle/
trailer combinations. Before beginning the
journey, check the trailer's documents to see
what the maximum permitted speed is.
For certain Mercedes-Ben zvehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. Refer to the "Technical Trailer towing
