Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low curb
R you forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
R the parking space is on a curb
R the system reads the parking space as being
blocked, for example by foliage or grass
paving blocks
R the area is too small for the vehicle to
maneuver into
R the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer :

; Parking symbol
= Detected parking space on the right
If the driver's seat belt is fastened and all
doors are closed, Active Parking Assist is acti-
vated automatically when driving forwards.
The system is operational at speeds of up to
approximately
22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides of
the vehicle.
Active Parking Assist will only detect parking
spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel
and are at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 40 in (1.0 m) longer than your
vehicle
R that are at right angles to the direction of
travel and at least 40 in (1.0 m) wider than
your vehicle i
Note that Active Parking Assist cannot
measure the length of a parking space if it is
at right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When the vehicle is driving at speeds of up to
approximately

20 mph (30 km/h), parking
symbol ; is shown as a status display in the
header.
The system detects and differentiates between
parking spaces which are parallel or at right
angles to the direction of travel. When a park-
ing space is detected, an arrow appears next
to parking symbol ; to indicate which side
the parking space is on. The parking space is
displayed while you are driving past it and until
you are approximately 50 ft (15 m) away from
it.
Active Parking Assist displays parking spaces
on the passenger side as standard. The park-
ing spaces on the driver's side are only dis-
played if you operate the turn signal on the
driver's side. When parking on the driver's
side, you must operate the turn signal until
you have started active parking assistance by
pressing the a button on the steering
wheel.
Parking G
WARNING
If you leave the driver's seat when the vehi-
cle is only being braked by Active Parking
Assist, the vehicle could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R the electrical system in the engine com-
partment, the battery or the fuses are
tampered with.
R the battery is disconnected.
R the vehicle is accelerated, e.g. by a vehi-
cle occupant.
There is a risk of an accident.
Before leaving the driver's seat, always
secure the vehicle against rolling away.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically during the
parking process. You are responsible for brak-
ing in good time. Driving systems

Notes on trailer towing
Important safety notes G
WARNING
Installing an unsuitable ball coupling may
overload the trailer tow hitch and the rear
axle. This is particularly likely in the case of
longer or differently angled ball couplings.
Consequently, the driving characteristics
may be significantly impaired and the trailer
may detach. This presents the risk of an
accident or even fatal injuries!
Install only a ball coupling that adheres to
the permissible dimensions and is designed
for your intended purpose for towing a
trailer. Do not make any changes to the ball
coupling or the trailer tow hitch. G
WARNING
If you install a ball coupling other than the
one delivered with the vehicle, the trailer
tow hitch and the rear axle may be overloa-
ded. This applies especially if the ball cou-
pling in question is longer or angled differ-
ently. 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 require-
ments. Do not modify the ball coupling or
the trailer tow hitch.
G
WARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driv-
ing and endanger other road users. There is
a risk of accident and injury, possibly even
fatal injuries.
Install and secure the ball coupling as
described in the ball coupling manufactur-
er's installation instructions. Make sure that
the ball coupling is correctly installed and
secured before every journey. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even roll-
over. There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combina-
tion 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
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 standing between the vehicle
and the trailer.
A trailer which is incorrectly coupled to the
towing vehicle could break away. A correctly
coupled trailer must be positioned horizontally
behind the towing vehicle. 168
Towing a trailer
Driving and parking

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
and decouple the trailer. Towing a trailer

Permissible trailer loads and trailer
drawbar noseweights
Weight information !
For vehicles with a permissible gross vehi-
cle weight of 6614 lbs (3000 kg), the per-
missible gross combination mass is less
than the sum of the permissible gross vehi-
cle weight plus the permissible trailer load.
Exceeding the permissible gross combina-
tion mass can lead to damage to the drive-
train, to the transmission or to the trailer
hitch.
If either the vehicle or the trailer is fully
laden, the permitted gross vehicle weight or
the permitted trailer load values are reduced
accordingly. In this case, you may only parti-
ally 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. If the trailer is
installed with a separate functional braking
system, then the maximum gross trailer weight
is 5000 lbs (2268 kg). G
WARNING
If you tow a trailer without a separate func-
tional braking system and a gross trailer
weight (GTW) of more than

1635 lbs
(750 kg), then the vehicle brake system may
overheat. This increases the braking dis-
tance and the brake system may even fail.
There is an increased risk of accident and
injury, possibly even fatal.
Always use a trailer with a separate func-
tional braking system when towing a trailer
with a gross trailer weight (GTW) of more
than 1635 lbs (750 kg).
The maximum noseweight of the trailer draw-
bar 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 always applies.
The gross combination weight rating (GCWR) is
calculated by adding the gross weight of the
trailer to the gross vehicle weight including a
driver's weight of approximately 150 lbs
(68 kg). The permissible Gross Combination Weight Rating is vehicle-specific and depends
on the equipment level.
When driving with a trailer, you should not
exceed the permitted Gross Combination
Weight Rating (GCWR).
The permissible values, which must not be
exceeded, can be found in your vehicle docu-
ments and on the trailer tow hitch type plates
for the trailer and the vehicle (
Y page

304).
The basic values approved by the manufac-
turer can also be found in the "Technical data"
section ( Y page 315). If the values vary, the
lowest value always applies.
Loading a trailer !
Utilize the maximum permissible nose-
weight as fully as possible. Do not allow the
weight to fall below the minimum permissi-
ble noseweight, otherwise the trailer may
come loose.
R The load must be distributed over the vehi-
cle and the trailer so as not to exceed either
the maximum permissible values for the
gross vehicle weight rating (GVWR) and
gross trailer weight (GTW), the gross combi-
nation weight rating (GCWR), nor the maxi-
mum permissible gross axle weight rating
(GAWR) and trailer drawbar noseweight rat-
ing of your vehicle.
R Add the drawbar noseweight on the ball
coupling (TWR) to the rear axle load. This
will prevent you from exceeding the permis-
sible gross axle weight (GAWR).
R Add the drawbar noseweight on the ball
coupling (TWR) to the vehicle payload. This
will ensure that you do not exceed the per-
missible gross vehicle weight rating (GVWR).
Checking the vehicle and trailer
weight R
Make sure the weights of the towing vehicle
and the trailer comply with the maximum
permissible values. Have the vehicle/trailer
combination weighed on a calibrated weigh-
bridge. The vehicle/trailer combination con-
sists of the towing vehicle including the
driver, passengers and load, as well as the
loaded trailer.
R Check the maximum permissible gross axle
weight rating of the front and rear axles
(GAWR), the gross trailer weight (GTW), the
gross combination weight rating (GCWR) 172

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.
