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 .

u co ..... N r--­N ..... 0 <( 0 00
Tongue weight
The maximum permitt ed tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded .
I f the tongue we ight is too low, th is affects t he
trailer's handling. For driv ing safety, we recom­
mend to always utilize the maximum permitted
tongue weight, but not exceed it. You can reach
it, for example, by distributing the cargo in the
trailer correctly.
You can determine the tongue weight, for exam­
p le, with a bathroom scale or a public weigh sta ­
tion .
The permitted tongue we ight of your veh icle can
be found in the vehicle documentation or in
¢page 370.
Load distribution
Poor cargo load and distribution can negatively
i mpact ve hicle handl ing .
-Store objects preferably in the vehicle luggage
compartment. The vehicle shou ld always carry
the heaviest possible load and the trailer
shou ld have the lightest possible load.
-Distribute the load in the tra iler so that the
heavy objects are as close to the axle as possi­
ble.
-Secure objects from slid ing out of p lace.
-Utilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the t ire pressure
sticker¢ page 335 .
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­
mendation .
W inter tires should be mounted on the vehicle
and on the trailer during winter temperatures .
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you must attach addit ional exterior m irrors. Adjust
them so you have a sufficient visibility behind
you .
Trailer towing
Exterior lighting
Follow the legal regu lations rega rding the light ­
ing equipment on your trailer. Contact an author­
ized Audi dea ler or authorized Audi Service Facili­
ty for more information.
Before starting to drive , check all lighting eq uip­
ment on the hitched trailer.
T he headlight range cont rol adjusts automat ica l­
ly to the light range of the headlights .
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer . The cha ins should hang
enough so that the trailer can drive around
curves . Howeve r, th ey must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The air suspens ion must be at the standard vehi­
cle height before you set the tongue weight on
the tra iler and hitch the
trailer ¢@ , ¢page 128,
Raising/lowering the vehicle.
For vehicles with a factory-installed trailer hitch,
the a ir suspension trailer mode w ill automatically
switch on if you connect the trailer cable to the
socket.
For vehicles with a retrofitted trailer hitch, you
must sw itch on the a ir suspension trailer mode
manua lly . Select in the Infotainment system:
IMENU I button> Vehicle> left cont rol button>
Vehicle settings > Air suspension: trailer. Switch
i t off again after towing a tra iler .
You can also sw itch off trailer mode manually
wh ile dr iving, for example, whe n using a bicycle
rack system.
If you have to dr ive through d ifficult road cond i­
tions, you can ra ise the vehicle again after hitch­
i ng the tra iler o r after adjusting the tongue
we ight.
(UJ} Note
Applies to: vehicles with air suspension
-Changes in temperature or load can affect
the height of the vehicle .

Ass is tanc e system s
Turn a ssist
When start ing to dr ive and up to speeds of maxi­
mum 6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning left or right (available in certain co untries). The
braking intervent ion causes your vehicle to stay
in its lane.
A WARNING
-Pre sense front cannot overcome the laws of
physics . It is a system des igned to assist and
it cannot prevent a collision in every circum­
sta nce. The d rive r must a lways i ntervene.
T he d river is always respons ib le for b raking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This cou ld increase your risk of a co llision .
-The system can deploy incorrectly d ue to
system -specific limits .
-Please note that the sensors and the camera
do not always detect all objects or lane
markings. This increases the risk of an acci ­
dent.
-Pre sense front does not react to people, an ­
ima ls or ob jects that are crossing the veh i­
cle's path or that are diff icu lt to detect
c::> &
in General information on page 103.
-Reflective ob jects s uch as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a coll is io n risk.
{UJ) Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody . Pre sense fro nt can be impa ired
by this. Have an authorized Aud i dealer or au­
thori zed Aud i Service Fac ility check the ir func­
tion.

ing yourse lf, by acce lerating not iceably or
by swerving.
-Keep in mind that pre sense front can brake
unexpectedly . A lways secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
-Specific pre sense front functions switch off
when the ESC is restricted or sw itched off

Assistance systems
Engine and automatic transmission
Depending on the mode , the engine and auto­
matic transmission respond more quickly or in a
more balanced manner to accelerator peda l
movements. In the sporty
Dynamic mode, the
transmission shifts at higher speed ranges.
Air suspension*
The air suspension* is an electronically-control ­
led air suspension and damping system. The
ad­
justment depends on the driving mode selected,
steering movements, the driver's braking and
ac­
celeration, and as the road surface, vehicle speed
and load. The veh icle ground clearance depends
on the mode selected and the speed .
The ground clearance increases significantly
when the vehicle is in the
Allroad mode . At
speeds from approximate ly SO mph (80 km/h) to
75 mph (120 km/h), the ground clearance
re­
duces in stages . When the speed decreases, the
ground clearance increases aga in automat ically .
The ground clearance is the lowest in
Dynamic
mode.
Suspension control*
The suspension control* uses sensors to record
information regard ing steering movements,
braking and acceleration operations by the driv­
er, road surface, dr iv in g speed, and load. This
makes it possible to adapt damping to the driv­
ing situation near ly in rea l time. With drive
se ­
lect, you can adjust the suspension contro l to be
sporty
( Dynamic ), comfortab le (C omfort ) or bal­
anced
(A uto ).
Steering
The power steering adapts. Ind irect steer ing that
moves easi ly as in
Comfort mode is especia lly
suited to long drives on highways. The
Dynamic
mode provides sporty, direct steering.
The following applies to vehicles with dynamic
steering* : the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the driver at all times . This
sets the steering to be less sensitive at higher
speeds in order to prov ide improved vehicle con­
trol. At reduced speeds, steering is more direct in
126
order to keep the steering effort as minima l as
possible when the driver is maneuvering the ve hi­
cle. At low and average speeds, dynamic steer ­
i ng* addit iona lly prov ides more respons ive steer­
i ng performance.
Sport differential*
As a component of the all whee l drive system
(quattro)
r=!> page 144, the sport differentia l dis ­
tributes the driving power to the rear axle
de­
pending on the s ituation. The distr ibut ion of
power varies depending on the selected mode
from moderate
(C omfort ) to sporty (Dynamic ).
The goal is a high level of ag ility and ability to ac­
celer ate on curves. The vehicle is very respons ive
to stee ring.
Adaptive cruise control (ACC)*
The behavior whe n accelerating can be adjusted
from comfortable to sporty, depending on the drive select mode . Adaptive cruise control also
r esponds to the driv in g behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty .
@ Note
Applies to: vehicles with a ir suspension
- Make sure there is enough clearance above
and below the vehicle when pa rking. Th e
height of the vehicle (ground clearance) can
change once it is parked due to temperature
fluctuations, changes to the load conditions
and changes to the driving modes.
- When transporting the vehicle on a car
car­
rier, train, ship or by other means, only tie
the vehicle down at the running sur face of
the tires, which is the outer c ircumference.
Securing the vehicle at the axle compo­
nents, suspension struts or tow ing eyes is
not perm itted because the pressure in the
air suspens ion struts can change during
transport. The vehicle may not be secured
sufficiently if this happens .
