Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent on
various factors. These include the position
and shape of the vehicles parked in front
and behind it and the conditions of the loca-
tion. It may be the case that Active Parking
Assist guides you too far into a parking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the curb. In this case, cancel the active
parking assistance.
R You can also engage transmission position
h prematurely. The vehicle redirects and
does not drive as far into the parking space.
If you change direction too early, parking
assistance is canceled and Active Parking
Assist is stopped. It is then not possible to
achieve a sensible parking position from the
current position.
Exiting a parking space In order that Active Parking Assist can assist
you when exiting the parking space, the follow-
ing conditions must be fulfilled:
R the border of the parking space must be
high enough at the front and the rear, a
curb, for instance, is not sufficient.
R the border of the parking space must not be
too wide. Your vehicle can be maneuvered
into a position at a maximum of 45° to the
starting position in the parking space.
R a maneuvering distance of at least

3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically when exiting
from the parking space. You are responsible
for braking in good time. 162

Ensure that the following weights are not
exceeded:
R the permissible 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
R the maximum permissible gross weight of
vehicle/trailer combination
The applicable permissible values that may not
be exceeded can be found:
R in your vehicle documents
R on the type plates for the trailer tow hitch
R on the type plates for the trailer
R on the vehicle identification plate
(Y page
304)
Where the values differ, the lowest is valid.
You will find the values approved by the manu-
facturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section (Y page 315).
Your vehicle behaves differently with a trailer
than without one.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is more susceptible to strong crosswinds
R requires more sensitive steering
R has a larger turning radius
This may impair the handling characteristics.
When towing a trailer, always adjust your
speed to suit the road and weather conditions.
Drive carefully. Maintain a safe distance.
If you require any further explanation regard-
ing the information contained in the Operating
Instructions, please contact a Mercedes-Benz
Commercial Van Center.
General notes R
Observe the legally permitted maximum
speed for vehicle/trailer combinations in
the relevant country, state or Canadian
province. Before beginning the journey,
check the trailer's documents for the maxi-
mum permitted speed of your trailer. This reduces the risk of accidents.
R Install only an approved trailer coupling on
your vehicle. Only use a ball coupling for
your Metris trailer tow hitch if it has been
approved for your vehicle. More information
on the availability, mounting and installation
of the trailer electrics is available at any
qualified specialist workshop.
R The trailer coupling is one of the most
important vehicle parts with regard to road
safety. Observe the notes on operation, care
and maintenance of the trailer tow hitch
(see the manufacturer's operating instruc-
tions).
R The bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
R Do not attach rented trailer tow hitches or
other detachable trailer tow hitches to the
bumper.
R Minimize the risk of damage to the ball cou-
pling. If you do not require the ball coupling,
remove it from the ball coupling recess.
You will find weight information under "Techni-
cal data"
(Y page 315).
The height of the ball neck changes according
to the load on the vehicle. If this is case, use a
trailer with a height-adjustable trailer drawbar.
Driving tips The maximum permissible speed for vehicle/
trailer combination depends on the type of
trailer. Before beginning the journey, check
the trailer's documents for the maximum per-
mitted speed of your trailer. Observe the
legally permitted maximum speed in the rele-
vant country, state or Canadian province.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
to when driving without a trailer and it will con-
sume more fuel.
On long and steep downhill gradients, select a
lower gear.
i This also applies if cruise control is activa-
ted.
This enables you to utilize the engine's braking
effect and you do not need to brake so heavily
to keep the correct speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need to brake additionally, to Towing a trailer
169
Driving and parking Z

Observe the following when towing a trailer:
R Practice driving around bends, stopping and
backing up at a place where there is no traf-
fic. This enables you to gain experience and
get used to the new handling characteris-
tics.
R Before driving, check:
- that the trailer tow hitch and ball coupling
are secure
- that the safety switch for a braked trailer
is functioning properly
- that the safety chains are secure and not
damaged
- that the electrical connections are secure
- that the lights are working
- that the wheels are in good order and the
tire pressure is correct
R Adjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
R If the trailer is equipped with a separate
functional braking system, check before
each journey whether the brakes are func-
tioning correctly.
R Secure the load on the trailer according to
the applicable specifications and current
standards on securing loads
(Y page 244).
R When driving with a trailer, check at regular
intervals that the load is secured and that
the brakes and lights are working.
R Bear in mind that the handling will be less
stable when towing a trailer than when driv-
ing without one. Avoid sudden steering
movements.
R The vehicle/trailer combination is heavier,
accelerates more slowly and has a
decreased gradient climbing capability and a
longer braking distance.
It is more susceptible to crosswinds and
requires cautious steering.
R If possible, do not brake suddenly, but
rather moderately at first so that the trailer
can activate its brakes. Then increase the
force on the brake pedal.
R If the automatic transmission repeatedly
shifts between gears when driving on
inclines, restrict the shift range. Select shift
range 4, 3, 2 or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine. R
When driving on a downhill gradient, shift to
a low gear and take advantage of the
engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
R If the coolant temperature increases dra-
matically while the air-conditioning system
is switched on, switch off the air-condition-
ing system.
Coolant heat can also be dissipated by
switching the airflow and the temperature of
the air conditioning to the maximum level.
Open the windows if necessary.
R When overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer
combination you need an additional dis-
tance before you can return to your original
lane. Uncoupling a trailer
G
WARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun
brake is engaged.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound-
ing of the overrun brake.
X Make sure that the selector lever of the
automatic transmission is in position P.
X Engage the vehicle's parking brake.
X Close all doors.
X Apply the parking brake of the trailer.
X In addition, secure the trailer against rolling
away with a wheel chock or similar object.
X Remove the trailer cable and safety chains

This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.

G
WARNING
If you operate information systems and com-
munication equipment integrated in the
vehicle when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the traffic
situation permits. If you are not sure that
this is possible, park the vehicle paying
attention to traffic conditions and operate
the equipment when the vehicle is station-
ary. G
WARNING
If you are driving and reach through the
steering wheel to operate the adjustment
knob, you could lose control of the vehicle.
There is a risk of an accident and injury.
Only operate the adjustment knobs when
the vehicle is stationary. Do not reach
through the steering wheel when driving.
You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer display only shows
messages and warnings from certain systems.
You should therefore make sure your vehicle is
operating safely at all times. If the operating
safety of your vehicle is impaired, stop the
vehicle as soon as possible, paying attention
to road and traffic conditions. Then consult a
qualified specialist workshop.
The accuracy of the speedometer and odome-
ter displays is legally prescribed. Determining
the speed is dependent on the wheel size or
the rolling circumference of the wheels. If you
change the wheel size on your vehicle, make
sure it is assigned to the correct wheel size
category ( Y page
278). If you change wheel
size category without recoding the control
unit, the speedometer indication will be inac-
curate. Driving safety and driving systems may
be impaired or detect a malfunction and shut
down.
