" N .... 0 00 \.J - Trailer towing Driving with a trailer
General information
Your veh icle is primar ily intended for transport­
ing people and luggage. However, if you dr ive
with a trailer , follow the technical requirements,
the operation and driving tips, and the legal reg­
u lations.
Driving with a trailer affects the vehicle 's fuel
consumption, performance and wear. It also re­
quires highe r 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
hitch mount and ball hitch. The trailer hitch must
be perm itted for the vehicle, the trailer and the
permitted total weight of the trailer being
pu lled. Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch 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 regularly if the trailer hitch is securely
mounted. A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If the tra iler has its own brake system, then fol­
l ow the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The coo ling sys­
tem must be designed for additiona l load and
contain enough coo lant
i::> @ .
@ Note
Longer inclines cannot be driven without a
suitab le cooling system, especia lly if t he out­
side temperatures are high . otherwise, this
increases the risk of engine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribut ion can negatively
impact vehicle handling.
- Store objects preferably in the vehicle luggage
compartment . The vehicle should always carry
the heaviest poss ible load and the trailer
should have the lightest possible load.
- Distribute the load in the trailer so that the
heavy objects are as close to the axle as poss i­
b le.
- Secure objects from sl iding out of place .
- Ut ilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure sticker
c::>page 215.
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­ mendat ion .
Winter tires should be mounted on the vehicle and on the trailer during winter temperatures.
Outside mirrors
If you cannot see the tra ffic behind the trailer
with the standard exterior mirrors, then you
81

Trail er to wing
must attach additiona l exterior mirrors . Adjust
them so you have a sufficient visibility behind
you .
Exterior lighting
Follow the lega l regulat ions regard ing the light ­
ing eq uipment on your trailer . Conta ct an author ­
ized Audi dealer or authorized Audi Service Facili­
ty for more information.
Before start ing to drive, check a ll l ight ing equip­
men t on the hitc hed trailer.
The headlig ht range contro l adjusts automatical­
ly to the light range of the headl ights.
Safe ty chain s
Make sure the safety chains are correctly applied
when pulling a trailer . The chains should hang
enough so t hat the trailer can dr ive around
curves. However, they must not touch the
g round .
Air su spension
Applies to: vehicles with air suspension
The air suspension must be at the standard vehi­
cle height before you set the tongue weight on
the trailer a nd h itch the trailer ¢@ ,
¢page 107,
Raising/lowering the vehicle.
For ve hicles w ith a factory-installed tra iler hitch,
the air suspension trailer mode will automat ically
sw itch on if you connect the trailer cable to the
socket.
For ve hicles w ith a retrof itted trailer hitch, you
must switch on the air suspension trailer mode
manually . Select in the Infota inment system:
ICARI function button > ( Car )* s yste m s contro l
button
> V ehicle setting s > Air su spen sion : trail ­
e r > On .
Switch it off again after tow ing a tra ile r.
You can also switch off tra iler mode ma nually
while driving, for example, when using a bicycle rac k system .
If you have to drive through difficult road condi­
tions, you can raise the vehicle aga in after hitch­
ing the t rai ler or after adjust ing the tongue
weight .
82
@ Note
Applies to: vehicles with air suspension
-Changes i n temperature or load can affect
the height of the vehicle .
- Set the air suspension to the standard veh i­
cle he ight, otherwise the applicable tongue
we ight no longer appl ies to your veh icle.
(D Tips
- Use chocks when park ing on inclines if the
trai ler is loaded.
- We recommend also hav ing the vehicle in­
spected between the inspection intervals if
you are towing a trailer frequently.
- Avoid driv ing with a trai ler dur ing the veh i­
cle break-in per iod.
Driving with a trailer
Driving with a trailer requires extra caution.
Sp eed
Adhere to t he lega l speed lim its . Fo llow the legal
regu lations
specific to the country.
As the speed increases, the dr iv ing stab il ity of
t h e tra ile r decreases. Therefore you should not
exceed the max imum lega l speed lim it w hen
t h ere are unfavorab le road, weather and/or wind
conditions. This especia lly applies when driving
downh ill.
Yo u m ust always red uce your speed as soon as
you notice even the slightest swinging motion o f
the trai ler . Never try to "straighten out" the trai l­
er by acce lerating.
The we ight d istr ibution is very poor if the vehicle
is empty and the trai ler is loaded. However if you
must drive under these circumstances, then drive
especially slowly .
Brakes
B rake in a time ly manner. Downs hift befo re dr iv ­
i ng down hill so that the engine can assist with
braking ¢&. .
When using a trailer w it h over run bra kes, fi rst
bra ke gently t hen q uick ly. This red uces the r isk of
j erking while braking if the trailer wheels lock up .

Description
Applies to: vehicles with Audi adaptive cruise control
Fig . 8 9 Detectio n ra n ge
The adaptive cruise co ntro l system is a comb ina­
tion of speed and d istance regula tion.
It assists
the dr iver by bot h regula ting the speed and
main taining a distance to the vehicle driving
ahead , within the limits of the system . If the sys­
tem detects and object ahead, adaptive cruise
control can brake and acce lerate your vehicle.
This makes driving more comfortable both on long stretches of highway and in stop-and-go
traffic .
What can adaptive c rui se control do?
T he adaptive cruise contro l system uses video, ra ­
dar and ultrasound . Objects driving ahead can be
recogni zed up to 650 feet (200 m) away.
On open roads with no traffic, it functions like a
cru ise control system . T he stored speed is ma in­
tained. When approaching an object ahead, the
adapt ive cruise control system automatically
brakes to match that object's speed and then
maintains the stored d istance. As soon as the
system does not detect a n object ahead, adaptive
cru ise con trol a cce lerates up to the stored speed .
In stop-and -go traff ic, adaptive cru ise control can
brake unt il the vehicle is s tat io nary and then be­
g in d riving aga in under certai n conditions
