Towing a trailer
PARKTRONIC detects a coupled trailer if your
vehicle is equipped with the corresponding elec-
trical installations for trailer towing.
PARKTRONIC is deactivated for the rear area
when you establish an electrical connectionbetween your vehicle and a trailer. If you use an
adapter for the socket, remove it from the
socket after detaching the trailer. Otherwise,
PARKTRONIC remains deactivated for the rear
area.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid. The system uses ultrasound sensors to
measure the road on both sides of the vehicle
and indicates suitable parking spaces. It can
then actively steer and brake the vehicle to help
you to park and exit the parking space.
Active Parking Assist includes the PARKTRONIC
parking aid which indicates visually and audibly the distance between your vehicle and an
obstruction. To do this, PARKTRONIC uses the ultrasonic sensors of the Active Parking Assist
(
Ypage 153).
Important safety notes
Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. You are responsible for safe
maneuvering, parking and pulling away. Make
sure that no persons, animals or objects are in
the maneuvering range.
When you deactivate PARKTRONIC, Active Park-
ing Assist will also be deactivated.
156Driving system
s
Driving an d parking

For vehicles with a trailer coupling installed, the
minimum length for parking spaces will be
slightly increased.
If you have attached a trailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between
your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
then deactivated for the rear area.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also display spaces
not suitable for parking, e.g.:
Rin a zone where parking or stopping is pro-
hibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
Ron narrow roads, drive as closely as possible
past the parking space.
Rparking spaces that are littered or overgrown
might be identified or measured incorrectly.
Rparking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
Rsnowfall or heavy rain may lead to a parking
space being measured inaccurately.
Rwhen transporting a load which protrudes
from your vehicle, you should not use Active
Parking Assist.
Rnever use Active Parking Assist when snow
chains are installed.
Ralways ensure that the tire pressure is correct
This has a direct influence on the parking
characteristics of the vehicle.
Rif you mount w heels with a different wheel
size, this will have a direct influence on the
parking result.
Rif you mount tires from another manufacturer,
this may have an influence on the parking
result.
Rif you drive slowly past the parking space, a
better parking result is achieved.
Rpay attention to the PARKTRONIC warning
messages (Ypage 155) during the parking
procedure.
Ryou can intervene in the steering procedure to
correct it at any time. Parking assistance will
then be canceled and Active Parking Assist
stopped.
Use Active Parking Assist for parking spaces
that are:
Rparallel or at right angles to the direction of
travel.
Ron straight roads, not bends.
Ron the same level as the road, e.g. not on the
pavement.
Detecting parking spaces
GWARNING
If there are objects above the detection range:
RActive Park Assist may steer too early
Rthe vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
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 cal-
culated, e.g. overhanging loads, overhangs or
truck loading ramps.
For further information on the detection range

Towing a trailer
Notes on trailer towing
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
GWARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-
tion is longer or angled differently. This could
seriously impair the driving characteristics
and the trailer can come loose. There is a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch.
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is a risk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal-
lation instructions. Make sure that the ball
coupling is correctly installed and secured
before every journey.
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/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.
You can attach carrier systems such as bicycle
racks or load-bearing implements on the ball
coupling. The maximum load-bearing capacity
of 165 lb (75 kg) applies when using carrier sys-
tems on the ball coupling.
Always observe the operating instructions pro-
vided by the manufacturers of the trailer cou-
pling and the ball coupling.
Couple and decouple the trailer carefully. When
backing up the towing vehicle, make sure
nobody is standing between the vehicle and the trailer.
A trailer which is incorrectly coupled to the tow-
ing vehicle could break away. A correctly cou-
pled trailer must be positioned horizontally
behind the towing vehicle.
Ensure that the following weights are not excee-
ded:
Rthe permissible noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle

This enables you to gain experience and get
used to the new handling characteristics.
RBefore 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
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer is equipped with a separate func-
tional braking system, check before each
journey whether the brakes are functioning
correctly.
RSecure the load on the trailer according to the
applicable specifications and current stand-
ards on securing loads (
Ypage 246).
RWhen driving with a trailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driving
without one. Avoid sudden steering move-
ments.
RThe 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.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the force on the
brake pedal.
RIf 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.
RWhen 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 instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-conditioning system is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switching the airflow and the temperature of
the air conditioning to the
maximum level.
Open t

he windows if necessary.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com-
bination you need an additional distance
before you can return to your original lane.
Uncoupling a trailer
GWARNING
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 rebounding of the overrun
brake.
XMake sure that the selector lever of the auto-
matic transmission is in position P.
XEngage the vehicle's parking brake.
XClose all doors.
XApply the parking brake of the trailer.
XIn addition, secure the trailer against rolling
away with a wheel chock or similar object.
XRemove the trailer cable and safety chains
and decouple the trailer.

Useful information
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 possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the 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 equip-
ment when the vehicle is stationary.
GWARNING
If you are driving and reach through the steer- ing 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 thevehicle 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.
GWARNING
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 mes-
sages and warnings from certain systems. You
should therefore make sure your vehicle is oper-
ating 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 spe-
cialist workshop.
The accuracy of the speedometer and odometer
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 cat-
egory (
Ypage 279). If you change wheel size
category without recoding the control unit, the
speedometer indication will be inaccurate. Driv-
ing safety and driving systems may be impaired
or detect a malfunction and shut down.

Tachometer
!
Do not drive in the overrevving range, as this
could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption
of your vehicle and harms the environment as
a result of increased emissions.
The red band in the tachometer indicates the
engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached.
Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Please bear in mind that the outside tempera-
ture display shows the air temperature meas-
ured and not the road temperature.

Changes in the outside temperature are dis-
played after a short delay.
Coolant temperature gauge
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
On vehicles without steering wheel buttons, you
can have the coolant temperature shown in the
