Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­my and performance.
Trailer towing not on ly places more stress on the
ve hicle, it also ca lls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
@ Note
If you are going to tow a trailer, you must ac­
tivate the tra ile r operation mode
¢ page 82, Operating instructions.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trai ler weight. The hitch must be suitab le
for your ve hicle and tra iler and must be mounted
securely on the vehicle 's chassis at a
technically
sound
locat ion . Use on ly a trailer hitch with a re­
movable ba ll mount . Always chec k w it h t he t rail ­
er hitch man ufactur er to make s ure t hat you a re
using the co rrect hi tc h.
Do not use a bumper hitch.
The hitch m ust be installed i n such a way that it
does not interfere with the impact -absorbing
bumper sys tem . N o mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck t hat all hitch mo unti ng
bol ts rem ain securely faste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hitch

Assist Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay un­
der a specified maximum speed.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly.
The . (USA models)/ . (Canada models) indi­
cator light and a message appear in the instru­
ment cluster display at the same time. The./
• indicator light and the message turn off if the
speed falls back below the stored maximum
speed .
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener­
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning threshold
The warning threshold is set in the Infotainment
system.
.. Select: the
ICARI function button > (Car)* Sys­
tems control button > Driver assistance >
Speed warning.
@ Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.

The speed is maintained by modifying engine
power or through an active brake intervention.
A WARNING
-Always pay attention to the traffic around
you when the cruise control system is in op­
eration . You are always responsible for your
speed and the distance between your vehi­
cle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy ra in and
hydroplaning), because this inc reases the
risk of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway exits
-
or in construction zones . ~

Ass is t
- Please note that unconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­ cause pressing the accelerator pedal over­
rides the cruise control system .
-If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is sw itched on, the braking function in
the system may be switched off. The rest of
the cruise control system f unctions remain

In stop-and-go traffic, adaptive cruise control can
brake until the vehicle is stationary and then be­
gin driving again under certain conditions
¢page 92.
Audi braking guard can warn you about an im­
pending collision and initiate braking maneuvers
¢page 94.
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 91, Switching on/off.
When driving, you can stop cruise control
¢
page 92 or change the speed ¢ page 92 at
anytime.
You can also set the distance to the object mov­
ing ahead and set the driving mode of the adap­
tive cruise control¢
page 93 .
General information
Applies to: veh icles with Audi adaptive cruise control
Fig. 91 Front of t he vehicle: sen sors and video came ra
The areas that contain the radar and ultrasonic
sensors and the video camera¢
fig. 91 must not
be covered by stickers, deposits or other objects
because they can interfe re with the function of
the adaptive cruise control system and braking
guard. For information on cleaning, refer to
¢
page 235. The same applies for any modifica­
tions made in the front area.
The function of the adaptive cruise control sys­
tem and brak ing guard is limited under some
conditions.
- Objects can only be detected when they are
within the sensor range¢
page 88 , fig. 90 .
Assist
- The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane.
- Objects th at are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves
¢page 90.
-With stationary objects ¢ page 90.
A WARNING ~
Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
always take action to avoid a collision. The
driver is always responsible for braking at the
correct time.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­ ing). Using the system under these condi­
tions increases the risk of an accident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the stored speed when in these situations.
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac ­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani­
mals, objects crossing the road or oncoming
objects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard rails, the entrance to a tunnel, heavy rain or
ice.

_&. WARNING
- Improper use of adaptive cruise control can
cause collis ions, other accidents and serious
personal injury .
- Never let the comfort and convenience that
adaptive cruise control and braking guard
offer d istract you from the need to be alert
to traff ic conditions and the need to rema in
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
contro l and braking guard have limits - they
will not slow the veh icle down or ma intain
the set distan ce when you drive towards a n
obstacle or something on or near the road
that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle .
If registered by the radar sensors, vehicles
or obstacles that are not moving can trigger
a collision warn ing and if confirmed by the
video camera, a n acute collision warning .
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly . The adap ­
t ive cr uise control cannot slow or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remember that the
automa tic braking func tion cannot br ing the
vehicle to a sudden or emergency stop un­
der these condit ions .
- T o prevent unintended operation, always
switch ACC off when it is not being used .
(U) Note
The sensors can be displaced by impacts or
damage to the bumpe r, whee l housing and
underbody. That cou ld affect t he adaptive
cruise control system and braking guard .
Have an authorized Audi dealer or authorized
Audi Serv ice Facility check their function.

In curves
Applies to: vehicles with Audi adaptive cruise control
Fig. 92 Ex am ple: dri ving into a curv e
When dr iving into a curve c:::> fig. 92 and out of a
curve , the adapt ive cruise control may react to an
object in the neighboring lane and apply the brakes . Yo u can prevent that by pressing the ac­
ce le ra to r peda l br iefly.
Stationary objects
Applies to: vehicles with Audi adaptive cruise control
F ig . 93 Exam ple: object chang ing la nes a nd stat ion ary ob ·
jec t
The adaptive cru ise control system only reacts to
objects that are moving or t hat the system has
already detected as moving . For example, it can
react when a vehicle that has already been de­
tected @ turns or changes lanes, but adaptive
cruise control does not react to a stationary veh i­
cle @.
