imately 2seconds.
PARKTRONIC is then
deactivated.
The indicator lamp of the
f button lights up
and the red segments in
the PARKTRONIC warn-
ing display go out.PARKTRONIC has malfunctioned and has switched itself off.
XIf problems persist, have PARKTRONIC checked at aqualified spe-
cialist workshop.
The PARKTRONIC warn-
ing displaysi mplausible
distances.
For example, all the seg-
mentsm ay be lit even
though there is no obsta-
cle present.The PARKTRONIC sensors are dirty or iced up.
XClean the PARKTRONIC sensors (Ypage 257).
XTurn the key to position 2again in the ignition lock.
The license plate or other parts attached near the sensors may not be
secured correctly.
XCheck the license plate and attachmentp arts near the sensors for
correct seating.
An external radio or ultrasonic source may be causing interference.
XCheck PARKTRONIC functions in adifferent location.
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 visuallya nd audibly
the distance between your vehicle and an
object .Todot his, PARKTRONIC uses the ultra-
sonic sensors of the Active Parking Assist
(
Ypage 150).
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.M
ake
sure that no persons, animals or object sare in
the maneuvering range.
When you deactivate PARKTRONIC, Active Park-
ing Assist will also be deactivated.
For vehicles with atrailer coupling installed, the
minimum length for parking spaces will be
slightly increased.
If you have attached atrailer 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 aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
result in acollision with another road user.
There is arisk of an accident.

Therefore notethe following:
ROnly installaball coupling that is approved
for your vehicle.
RBefore the journey, make sure that the ball
coupling is correctly installed and secured.
To do this, observe the operating instruc-
tions of the ball coupling manufacturer.
RDo not make any modification stothe ball
coupling or the trailer tow hitch.
You must observe the operating instructions
of the trailer tow hitch or ball coupling manu-
facturer.
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is arisk
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 arisk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasingt he 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 noseweight of 165 lb
(75 kg) applies when using carrier systems 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 standin gbetween the vehicle and the
trailer. At
railer which is incorrectly coupled to the tow-
ing vehicle could break away.Ac orrectly 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
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
Rthe maximum permissible gross weight of
vehicle/trailer combination
The applicable permissible values that may not
be exceeded can be found:
Rin your vehicle documents
Ron the type plates for the trailer tow hitch
Ron the type plates for the trailer
Ron the vehicle identification plate
(Ypage 294).
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 "Technical
data" section (
Ypage 305).
Your vehicle behaves differently with atrailer
than without one.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris more susceptible to stron gcrosswinds
Rrequires more sensitiv esteering
Rhas alarger turnin gcircle
This may impair the handling characteristics.
When towing atrailer, alwaysa djust your speed
to suit the road and weather conditions. Drive
carefully. Maint ainasafe

RWhen driving withatrailer, 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 atrailer than when driving
without one. Avoid sudden steerin gmove-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has adecreased
gradient climbing capability and alonger
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 forceont he
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.
Drivin ginal ow gear and at alow speed
reduces the risk of damaging the engine.
RWhen driving on adownhill 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-conditionin gsystem is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switchin gthe airflow and the temperature of
the air conditioning to the maximum level.
Open the 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 atrailer
GWARNING
If you uncouple atrailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is arisk of injury.
Do not uncouple atrailer if the overrun brake
is engaged.
!Do not disconnect atrailer 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 withawheel chock or similar object.
XRemove the trailer cable and safety chains
and decouple the trailer.
Permissible trailer loads and trailer
drawbar noseweights
Weight information
!For vehicles with apermissible gross vehicle
weight of 6724 lbs (3050 kg), the permissible gross combination weight is less than the sum
of the permissible gross vehicle weight plus
the permissible trailer load. Exceeding the
permitted gross combination weight could
damage the powertrain ,transmission or
trailer tow hitch.
If either the vehicle or the trailer is fully laden,
the permitted gross vehicle weight or the per- mitted trailer load values are reduced accord-
ingly. In this case, you may only partially load
the trailer or the vehicle.
The gross trailer weight (GTW) is calculated by
adding the weight of the trailer to the weight of
the load and equipment. The permissible gross
trailer weight is 5000 lbs (2268 kg).
The maximum noseweight of the trailer drawbar
on the ball coupling is 500 lbs (227 kg). The
actual noseweight may not exceed the value
given on the identification plates of the trailer
tow hitch or the trailer. If the values vary, the
lowest value alwaysa pplies.
The gross combination weight rating (GCWR) is
calculated by adding the gross weight of the
trailer to the gross vehicle weight including a
