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 coo lant ~@ .
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 376.
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 .

Ass is tanc e system s
the cruise control from braking. This is be ­
cause pressing the accelerator pedal over­
rides the cruise contro l system .
- If a brake system ma lfunction 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 functions remain act ive as long as
the @;\l)~ij (USA models) /
Bl (Canada models) indicato r light is on.
@ Note
Before driving downhill a long distance on a
steep hill, decrease you r speed and select a
lower gear. This makes use of the eng ine
brak ing effect and re lieves the bra kes.
(D Tips
The b rake l ights turn on w hen the brakes a re
app lied automat ically .
Changing the speed
Applies to: vehicles with cruise control system
.,. To inc rease/decrease the speed in 1 mph (1
k m/h) increments, br ie fly
tap the leve r toward
0 10 ¢ page 95, fig. 89 to the f irst leve l.
.,. To increase/decrease the speed in S mph (10
km/ h) increments, br iefly
tap the leve r toward
0 10 to the second level.
.,. To increase or decre ase the speed quickly, hold
the lever toward
0 10 to the first or second
level until the des ired speed is reached .
Overriding the speed
Applies to: vehicles with cruise control system
You can p ress t he accelerator pedal to inc rease
your speed, for examp le if you want to pass
someo ne. The speed yo u se t earlier w ill res ume
as soon as yo u release the accelerator peda l.
H oweve r, if you are exceeding the stored speed
by a cons ider able amo unt for a long time , the
cr uise con trol sys tem w ill tempo rar ily switch off.
The
[ij;\l)~ij (USA models) tBI (Canada models) in ­
dicator light in the instrument cluster turns off
and the stored speed is maintained .

::r ' 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. 100 .
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
ACC: R + B ac­
ti ve
in the instrument cluste r indicates the ava il­
ab ility of the predictive control.
T he
'?·;SOmh symbo l appears when the system
is reg ulating the speed to match a speed lim it. If
this is the case, the system is regulating a speed
of SO mph (80 km/h) . The speed is then taken
over by the adaptive cru ise control. The speed in
the speedomete r LE D ring ad justs to the speed to
be maintained ¢page 104, fig. 99.

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.

:E ' 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 ¢

ing, see¢ page 351 . The same applies fo r any
modifications made in the front area .
In some dr iving situations, the adap tive c ruise
contro l func tion is restricte d:
- Veh icles can on ly be detected when they are
w ith in the sensor detection zones
¢ page 102,
fig. 94 .
-The system has a limited ability to detect
ve hicles that are a short dis tance ahead, off to
t he s ide of your veh icle or moving i nto yo ur
lane.
- Objects that are d ifficult to detect s uch as mo­
tor cycles, veh icles with high gro und clea rance
or an overhanging load are detected late or not
detected at all.
- When driving through curves
¢ page 104.
-W hen the veh icle is sta tionary ¢ page 104 .
A WARNING
Always pay atten 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 distance to other veh icles.
The adaptive cruise control is used to ass ist
you. The driver must always take action to
avoid a collision . The driver is always responsi ­
b le for braking at the correct time.
- For safety reasons , do not use adaptive
cru ise cont rol when the road surface is in
poor condi tion and/or in bad weather condi­
tions (such as ic e , fog, gravel, heavy rain and
hyd roplani ng) . Using the system under
these co ndi tions i ncreases the ris k of an a c­
cident.
- Sw itch adaptive cru ise cont rol off tempo ra­
r ily when dr iving in tu rning lanes, on e x­
p re ssw ay ex its (except if pre dictive control
is switched on) or in construct io n zones .
This prevents t he vehicle f rom acce le rating
to the stored speed when 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 istance regulat ion .

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.

Audi pre sense
Introduction
Applies to: ve hicles w ith Audi p re se nse
W ith in the limits of the system, the pre sense
functions can in it iate measures in particularly
dangerous s ituat ions to protect the ve hicle pas ­
sengers and ot her r oad users.
- Due to the interl ink ing of various vehicle sys­
tems , crit ica l dr iv ing s ituat ions can be detected
by
pr e s ense basic and measu res fo r preventa­
t ive occ upan t protect ion are can be initiated.
- T he
pre sen se front system uses the data from
t h e adapt ive cr uise control* radar sensors and
t h e camera to calc ulate the probab ility of a col ­
lision . Within the limits of the system, an im ­
pending collision with vehicles can be detected
in both urban and rural speed ranges. In this
case, the system warns the driver visually,
acoustically and with a jerk on the brakes if nec­
essary . If needed, it can initiate a partial or fu ll
deceleration to reduce the collision speed or to
avo id the co llision unde r ce rtain c ircumstances .
In conjunct ion with p re sense basi c/rear, the
front safety belts are also revers ibly tensioned
whe n needed. The pre sense front is also act ive
when adaptive cruise control* is switched o ff.
- Pr e se nse rear con tains pre sense basic func ­
tions. It uses the data from the side assist* ra­
dar sensors and calc ulates within the limits of
the system the probability of a rear end colli ­
sion with the vehicle behind you . Pre sense rear
is also active when s ide assist* is switched off .
112
-Within the limits of the system, pre sen se cit y
uses the camera data and can detect an im ­
pending collision with vehicles and pedestrians .
In this case, the system warns the driver visual­ ly, acoustical ly and w it h a jerk on the brakes if
necessary . If needed, it ca n initiate a full dece l­
erat ion to reduce t he coll is ion speed or to avoid
the collision under certa in circumstances . In
conjunction with p re sense basi c/rear, the front
safety belts are a lso reve rsibly te nsioned whe n
needed.

Descr iption
Within the limits of the system, pre sense front
can warn yo u of impending coll is ions and in itiate
the corresponding brak ing maneuvers or the sup­
port ing measures when avoiding a co llision .
If detected in time, the system can rank the dan ­
gerous situation as cr itica l if a vehicle driving
ahead brakes sudden ly, if you r own vehicle is ap­
proaching a s ignificantly s lower vehicle at h igh
speed or when there is an oncom ing vehicle dur­
i ng a tur ning maneuve r.
If detection is not poss ible, then pre sense front
does not react.
Warnings
The system recognizes various dange rous situa ­
tions. The
early warning occurs if:
- a vehicle d riving ahe ad brakes s udden ly,
- yo ur own vehicle approaches a s ignificant ly
s lower veh icle o r st ation ary veh icle in the dire c­
t ion of t ravel.
ll This is not availa ble in so m e co untrie s.
A ss istance systems
When this warning occurs, it may on ly be possi ­
ble to avoid a co llision by swerving o r braking
strongly . The message
Audi pre sense.
¢ fig . 108 and a wa rning tone will warn you
about the danger .
If you do not react enough or not at all to a dan­
gerous sit uat ion that was detected by the sys ­
tem, p re sense front provides assistance by ap­
ply ing the b rakes .
If a collision is imminent, the system will first
provide a n
acute warning by braking sharply . You
will a lso warned by an indicato r in the instr ument
cluster display¢
fig. 108 . If you do not react to
the acute warning, pre sense front can brake w ith
i ncreas ing fo rce wi thin the limits of the
system

even t of a co llision . At low vehicle speeds, p re
sense fron t can ini tia te a complete dece le ra tion
shor tly be fore a collision wi th a ve hicle dr iving
ahead

are not braking strong ly enough when a co llision
is imminent, it can increase t he b raking force.
T he following fu nctions t rigge r in conjunction
with pre sense basic/rea r at co rresponding vehi ­
cle speeds:
- Reve rsible tens ion ing of the front safety bel ts.
- Clos ing the windows and sun roof* .
- Infla ting the s ide bo lsters* in the sea t backrest
