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.
118
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 ¢@ .
@ Note
Longer incl ines cannot be driven wi tho ut a
suitab le cooling system, especia lly if the out ­
side temperatures are high . ot herwise, this
i ncreases the risk of eng ine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Yo ur vehicle can only be ope ra ted with class 1 or
class 2 trai le rs.
Load distribution
Poor cargo load and distr ib ution can negatively
i mpact vehicle handling . T o have the lowest im­
pact as poss ible, load the tra ile r according to
t h ese cr ite ria :
- Store objects preferably in the vehicle luggage
compartment . The vehicle should a lways carry
the heaviest poss ib le load and the trailer
should have t he lig htest poss ible load .
- Dist ribute the load in the t railer so that the
heavy objects a re as close to the axle as poss i­
ble.
- Secu re objects from s lid ing o ut of place.
- Ut il ize the maximum permitted tongue we ight
if poss ible .
Tire s
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure
st icker ¢ page 341.
If necessary, also adjust the t ire pressure on the
trailer acco rding to the manufactu rer's recom­
mendat ion.
Winter tires should be mounted on the vehicle and on the trailer during w inter temperatures .

Outside mirrors
If yo u cannot see the traffic behind the tra iler
with the standard exterior mirrors, then you
must attach additiona l exterior mirrors . Adj ust
them so you have a sufficient visibility behind
you .
Exterior lighting
Follow the legal regulat ions regard ing the light­
ing equipment on your trailer . Contact an author ­
ized Audi dealer or authorized Audi Service Facili­
ty for more information.
Before starting to drive, check all lighti ng equip­
ment on the hitched trailer.
The headlight range contro l adjusts automatical­
l y to the light range of the headl ights.
Safety chains
Make sure the safety chains are correctly applied
when pull ing a trailer . The chains should hang
enough so that the trailer can dr ive around
curves. However, they must not touch the
g ro und .
(D Tips
-Use chocks whe n parking on incl ines if the
trailer is load ed.
- We recommend also hav ing the veh icle in­
spected between the inspect ion intervals if
you are towing a trailer frequently.
- Avo id driving with a trailer during 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
regulations specific to the country.
As the speed increases, the driving stability of
the trai ler decreases. Therefore you should not
exceed the maximum legal speed limit when
u. there are unfavorable road, weather and/or wind 00
~ conditions . This especially applies when driving
~ downhill.
0 N > 00
Trailer towing
You m ust always reduce your speed as soon as
you notice even the slightest swinging motion of
the tra iler. Never try to "stra ighten out" the tra il­
er by acce lerating.
T he weight distribution is very poor if the vehicle
is empty and the trai ler is loaded . However if you
must drive under these circumstances, then dr ive
especially slowly .
Brakes
Brake in a timely manner. Downshift before driv ­
ing down hill so that t he engine can assist with
braking ~.&. .
When using a trailer w it h overrun brakes, first
brake gently then quickly. This reduces the r isk of
jerking while braking if the trailer wheels lock up .
Engine coolant temperature
Pay attention specifically to the coo lant tempera­
ture display when there are high outside temper­
a tur es, and when driving on long inclines
~page 11. Shift to a hig her 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.

Speed warning system
Description
Applies to: veh icles 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 warni ng tone will sound as soon as your speed
exceeds the sto red value slight ly. The
[OJ (USA

the co rresponding message appear in the inst ru­
ment cluster display at the same time. The
[C]
(USA models)/ [ej (Canada mode ls) indicator
light and the message turn off w hen the vehicle
speed drops 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 ge ner­
al speed limit or if there is a specified maximum
speed for winter tires.

Audi drive select
Introduction
App lies to : vehicles wi th Audi drive se lec t
Audi drive select makes it poss ible to experience
different types of vehicle settings in one vehicle.
The dr iver can select from three modes,
Comfort ,
Auto
and Dynamic , using the ~.'/:.1 button in the
center console or by using the Infotainment sys­
tem. This allo ws you to switch between a sporty
and a comfo rtable driving mode, for example. In
the
Individual* mode, the settings can be adjust ­
ed to your personal preferences . This makes it
possible to comb ine settings such as a sporty en­
gine setting with light steering.

mat ic transmission * respond more quickly or in a
more balanced manner to accelerator pedal
movements . In the sporty dynamic mode, the
transmission shifts at higher speed ranges.
Suspen sion control (Audi magnetic ride) *
The s uspension contro l uses sensors to reco rd in­
formation regarding steering movements, brak ­
ing and acce leration operations by the driver, as
well as information abo ut th e road s urface, driv ­

can adjust the suspens ion control to sporty (dy­
namic), comfortable (comfort) or balanced (au­
to) .
Steering
T he steering adapts in terms of steering assis ­
tance. There are different modes
¢ page 142 .
Indirect steering that moves easily as in comfort
mode is especia lly su ited to long drives on a high ­
way . The dynam ic mode p rovides sporty, d irect

The closer you get to the obstacle, the shorter
the interva l between the audible signals. A con­
