Trail er to wing
Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso re­
quires higher concentration from the driver .
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury .
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
92
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h
coolant ~@ .
A WARNING -
- Never mount a "weight -distributing" or
"load-balancing" trailer coupler as the trail­
er hitch. The ve hicle was not des igned for
these types of tra iler h itches. The tra iler
h itch can malfunction and t he tra ile r can
b reak off from the vehicle.
- If t he tra ile r i s equ ipped w ith elect ronic
brakes, these brakes can not be activated by
a facto ry-installed control system, whi ch in­
creases the r isk of an accide nt.
- To red uce the r is k of injury, always remove
the ball hitch mount if no tra ile r is mo unt ­
ed.
@ Note
L onge r incl ines cannot be dr iven without a
su itab le cooli ng system, especially if the out­
s ide temperatu res a re high. ot herwise, this
i nc reases the risk of eng ine da mage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
The permitted towing capacity must not be ex ­
ceeded under any
circumstances ~ page 370.
You can dr ive up larger inclines if you are not us­
i ng the maximum towing capacity.
The towing capacities given only apply to e leva ­
tions up to 3,200 ft (1,000 m) above sea level. As
the e levation increases, the engine power de­
creases due to the decreasing air pressures. T his
reduces the hill climb ing ability and towing ca­
pac ity . For every additional 3,200
ft (1,000 m),
t h e maximum permitted tow ing weight must be
r educed by app roximately 10% . T he pe rm itted
tow ing weight is t he comb ined we igh t of the
( loaded) vehicle and the (loaded) trailer .

Trail er to wing
- Set the a ir suspension to the standard vehi ­
cle height, otherwise the applicab le tongue
weight no longer applies to your vehicle.
(D Tips
- Use chocks when parking on incl ines if the
trailer is loaded .
- We recommend also having the vehicle in­
spected between the inspection intervals if
you are towing a trai ler frequent ly .
- Avo id driving with a trailer d uring the vehi ­
cle break-in period .
Driving with a trailer
Driving with a trailer requires extra caution .
Speed
Adhere to the legal speed limits. Follow the legal
regulat ions spec ific to the country.
As the speed increases, the driving stability of
the trailer decreases . Therefore you should not
exceed the maximum legal speed l imit whe n
there a re unfavorabl e road, weathe r and/or wind
conditions. This especially appl ies when dr iv ing
downhill.
You must always reduce you r speed as soon as
you not ice even the s lightest sw inging motion of
the t railer. Neve r try to "straighte n ou t" the t rail­
e r by accelera ting.
The weight distribution is very poor if t he veh icle
is empty and the t railer is loaded . H oweve r if you
m ust dr ive under these c ircumstances, t hen d rive
espec ially slowly.
Brakes
Brake in a t imely manner . Downshift before driv­
i n g downhill so that the engine can assist w ith
b raking
¢ ,&. .
When us ing a tra iler with overrun brakes, first
brake gently then qu ickly . This reduces the risk of
je rk ing w hile brak ing if the tra ile r w heels lock up .
Engine coolant temperature
Pay attention specif ica lly to the coolant tempera­
ture display when there are h igh outside tempe r­
atures, and when dr iv ing o n long inclines
94
¢ page 11. Shift to a higher gear in a timely man­
ner .
A WARNING
Constant braking causes the brakes to over­
heat and substantially reduces braking per­
formance, increases braking distance or caus­
es complete failure of the brake system.

Assistance systems Speed warning system
Description
App lies to: vehicles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system .
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
(Ol (USA
models)/
(01 (Canada models) indicato r light
and a message appear i n the ins trumen t cluster
d isplay at the same time. The
(Sl / (Ol indicator
light and the message turn
off if the speed falls
back below the stored maximum speed .
Sett ing a threshold is recommended if you would
like to be reminded when yo u reach a certa in
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
Select in the I nfotai nment system: IMENU I but­
ton
> Ve hicle > le ft control button > Dri ver a ssis ­
tan ce
> Speed warning > Manual.
@ Tips
Regard less of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.

Description
The predictive cont rol 1 l uses the map info rma ­
tion from the navigation system in order to react proactive ly when driving. Information from the
cam era-based traffic sign recognition * is a lso ap ­
plied to recognize traffic
signs ¢ page 97. When
coming up to areas wi th speed limits or changes
in the course of the road (such as curves, inter­
sections or traffic c ircles), the system brakes au ­
tomatically and then accelerates back up to the
set speed .
Overriding control
The driver can override the predict ive control at
a ny time by press ing the accelerator or brake
pedal. If the system changes the vehicle speed to
adapt to speed limits, you ca n cha nge the speed
usi ng the lever
¢ page 106, fig. 105 .
Always switch off the predictive control in
the following situations:
- When increased atte ntion is needed from the
drive r.
- In poor weat her cond it ions such as snow or
heavy ra in.
- When driving on roads in poor condition .
Indicator in the instrument cluster display
When switching on the adaptive cru ise cont rol
for the first time, the message

A WARNING
-
- Read the wa rnin gs on ¢ .&. in General infor­
mation on page 103
and on¢ & in De­
scription on page
97.
- Pay attent ion to traffic and the a rea around
your veh icle when pred ictive cont rol is
sw itched on. The driver is always responsi­
ble for assessing the traffic situation.
- There is an increase in the risk of an acci­
dent, because the system does not consider
"right of way" rules and also does not re ­
spond to traffic lights .
- The system only cons iders t raff ic signs that
g ive a speed lim it .
- The permitted speed can be exceeded if the
adaptation to a speed lim it is incorrect . The
d river is responsible for adher ing to the pe r­
mitte d speed .
- The s peed at w hich a curve is dr iven th rough
does not necessarily match your own driving
s tyle. Brake the vehicle yo urself whe n need­
e d t o redu ce the risk of an a ccid en t.
0) Tips
- If a speed lim it is detected, the stored
speed is also adjusted in the speedometer
LE D line when the ada ptive cru ise control is
n ot a ctive .
- The adaptat ion by the system depends on
t he driving mode se t in dr ive se lec t*.
- Switching off predict ive con trol, fo r exam­
ple whe n driving in low t raff ic zones, does
101

Ass is tanc e system s
not cause the adaptive cruise control to
switc h off .
- After switching on t he ignit ion, the system
initially adj usts to a speed of 80 mph
(130 km/h) when driving onto highways
without a speed limit. Then the system ad­
justs to the last speed stored by the driver.
- There is no adaptation to speed limits when
driving thro ugh h ighway interchanges and
when driving on or off the expressway.
- There is no pred ictive control at speed limits
under 20 mph (30 km/h).
- If a speed limit is only detected by the cam ­
era and the actua l speed is significantly
higher, then the speed limit will blink in the
display u ntil you have reached the requ ired
speed

- Incorrect values from the camera-based
traffic s ign recogn ition* or outdated naviga­
tion system map data can lead to incorrect
or implausible co ntro l.
- When route guidance is switched on, the system adapts to the route provided by the
navigation system. Driving w ithout route

Audi adaptive cruise control
Description
Applies to: vehicles with Audi adaptive cruise control
Fig. 99 Detect ion ra nge
The adaptive cru ise cont rol system is a comb ina­
t ion of speed and distance regu lation .
It assists
t h e d river by bo th regu lating the speed and
maintain ing a d istance to the vehicle driv ing
ahead, within the limits of the system.
If the sys­
tem detects a vehicle d riving ahead, the adaptive
cruise contro l can brake and accelerate your vehi ­
cle. T his makes driving more comfortable both
o n long stretches of highway and in stop -and-go
traffic.
What can adapti ve cruise control do?
The adaptive cru ise control system uses video, ra­
dar, ultrasound and navigation data . Vehicles
driv ing ahead can be recognized up to 650 ft
(200 m) away .
Pred ictive functions offer the driver additional
comfort and contr ibute to the reduct ion in fuel
consumption and
CO2 em issions Q page 100. IJIJ,

On open roads with no traffic, it functions like a
cruise control syst em . Th e stored spe ed is main­
tained. When approach ing a veh icle driving
ahead, the adaptive c ruise control system auto­
mat ica lly brakes to mat ch that vehicle's speed
and then maintains the set distance . As soon as
the system does not detect a vehicle driving ahead, adaptive cruise contro l accelerates up to
the stored speed.
In stop -and -go traff ic, adaptive cru ise control can
brake unt il the vehicle is stat io nary and then can
also start driving again automatically under cer­
tain
condi tions ¢ page 106.
In traffic jams or stop -and -go traffic, traffic jam
assist can assist the
driver ¢ page 109 .
Which function s can be contr olled ?
When you switch adapt ive cruise control on, you
can set the current speed as the "control speed"
¢ page 104, Swi tching on/off.
When driving, you can stop c ruise contro l
¢ page 107 or change the speed ¢ page 106 at
any time.
You can a lso set the distance to the vehicle driv ­
ing ah ead and s et the driv ing mode of the adap­
tive cruise
control ¢ page 10 7.
General information
Applies to: ve hicles with Audi adaptive cruise co ntro l
Fig. 10 0 Fro nt of the v ehi cle : se nso rs a nd v ideo cam era
The areas w ith the rada r and u ltrasonic sensors

modifications made in the front area .
In some dr iving s it u ations, the adaptive c ruise
contro l func tion is restricte d:
- Veh icles can on ly be de tected when they are
w ith in the sensor detection zones
¢ page 102,
fig.
99 .
- The system has a limited ability to detect
ve hicles that are a short dis tance ahead, off to
t he side of your ve hicle or movi ng i nto yo ur
lane.
- Ob jects that are d ifficult to detect s uch as mo­
torcycles, veh icles with high gro und clea rance
or an overhanging load are detec ted late or not
detected at all.
- When driving through curve s

A WARNING
Always pay at ten tion to the traffic around you
when adaptive cru ise con trol is switched on .
As the driver, you are still responsible for your
own speed and the d istance to other veh icles.
The adaptive cruise cont rol is used to assist
you. The driver must always take action to
avoid a collision . The driver is always responsi ­
bl e for braking at the correct t ime.
- For safety reasons, do not use adaptive
cr uise control when the road surface is in
poor condi tion and/or in bad weather condi­
tions (such as ice, fog, gravel, heavy rain and
hyd roplani ng) . Using the system under
these co ndi tions i ncrea ses the r is k of an a c­
cide nt.
- Sw itch adaptive cru ise con trol
off tempora­
r ily when dr iv ing in tu rning lanes, on e x­
p re ssway ex its (except if predictive con trol
is switched on) or in construct io n zones .
This prevents the vehicle from acce lerating
to the stored speed w hen in these situa­
tions.
- The adaptive cruise contro l system will not
brake by itself if you put yo ur foot on the ac­
celerator pedal. Doing so can over ride the
speed and d ista nce regulation .

Assistance systems
-When approaching stationary obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function.
- Adaptive cruise control does not respond to
people, animals, or cross ing 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.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody . Th is can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
function.

Within the limits of the system, adaptive cruise control can react to stationary vehicles
¢
fig. 102, as long as you are driving slower than
30 mph (SO km/h) and the system classifies the
possible passing maneuver as low . For example,
if a vehicle that was already detected
