procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some cir
cumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. Thi smay lead to a
collision. For this reason, you shoul davoid
using Active Parking Assist in such situatio ns.G
WARNING
Th ef ront of th evehicle will veer out in the
direc tion of the oncomin gtraffic during the
parking operatio n. Insome cases the vehicle
will also take you onto section softhe oncom-
ing lan eduring the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist
parking procedure. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
Use Active Parking Assis tfor parkin gspaces:
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, driv easclosely as possi-
ble past the parkin gspace.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incor rectly or not at all.
R snowfall or heavy rain may lea dtoap arking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 192 )warning message sduring the
parking procedure.
R you can intervene in the steering procedure
to correc titatany time. Active Parking
Assist will then be cancelled. R
whe ntransporting aload which protrudes
from your vehicle, you should not use
Active Parkin gAssist.
R never use Ac tive Parkin gAssist when snow
chains or an emergenc yspare wheel are
fit ted.
R mak esure that the tyre pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the wa yyourv ehicle is positioned in the
parking space after parking is dependent
on various factor s. Theseinclude the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. In some cases, Active Parking
Assist may guid eyou too far int oaparking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the kerb. If necessary, you should abort the
parking procedure with Active Parking
Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
ag ear be changed too earl ytoa chieve a
sensible parkin gposition ,the parkin gpro-
cedure wil lbeaborted.
! If unavoidable, you should driv eover
obstacles such as kerb sslowly and not at
as har pangle .Otherwise, you may damage
the wheels or tyres.

Do not exceed the maximum noseweight.
When driving with aloaded carriersystem,
always adjust your drivin gstyle to th eprevail-
ing road, traffic and weather conditions and
drive par ticularly carefully.
You can use carrier sys tems, e.g. bi cycle
racks or load-bea ringimplements on th eball
coupling. The maximum noseweight of 75 kg
applies when usin gcarrier system sontheball
coupling.
General information i
Chec kthe tyr epressure when towin ga
trailer. You will find the values in the tyre
pressure table in the fuel filler flap of the
vehicle (Y page 359).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 378).
The maximum noseweight of the trailer draw-
bar on the ball coupling is 18
.H owever, the
actual noseweight must not exceed the value
given on the trailer tow hitc hortrailer identi-
ficatio nplates. 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 ma ycome loose.
Bear in min dthat the payload and the rear
axl eload ar ereduced by the actual nose-
weight.
Please note that when towing atrailer, PARK-
TRONIC (Y page 191) and Blind Spo tAssist
(Y page 208) ar eonly available with limita-
tions ,orn ot at all.
i On vehicles withou tlevel control, the
height of the ball couplin gwill alter accord-
ing to the load placed on the vehicle. If nec-
essary, use atrailer wit haheight-adjusta-
ble drawbar. Driving tips i
Observ ethe information on ESP ®
trailer
stabilisation (Y page 65)and on pull ing
away with atrailer. (Y page 141).
Vehicles wit hthe ON&OFFROAD package:
selec tthe trailer program (Y page 219) with
the off-road program selector wheel in the
cen treconsole.
Th em aximum permissible spee dfor vehicle/
trailer combination sdepends on the type of
trailer .Befor ebeginning the journey, check
the trailer's documents to see what the max-
imu mpermitted speed is. Observ ethe legally
prescribed maximum speed in the relevant
country.
For certai nMercedes-Ben zvehicles, the max-
imu mp ermissible rear axle load is inc reased
when towing atrailer. Refer to th e"Techni cal
data" section to fin dout whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing atrailer,
th ev ehicle/trailer combination may not
exceed amaximum spee dof100 km/ hfor
reasons concer ning the operating permit.
Thi salso applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing atrailer, your vehicle's handling
characteristics will be differe ntin comparison
to when drivin gwithout atrailer and it will
consume more fuel.
On long and stee pdownhil lgradients ,you
must select shift range 1,2or 3in good time.
i This also applies if you have activated
cruise con trol, SPEEDTRONIC or DI S-
TRONIC PLUS.
This will use the brakin geffect of th eengine,
so les sbraking wil lberequired to maintain
the speed. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly .Ifyou need
additional braking, depress the brake pedal
repeatedly rather than con tinuously.
