Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­my and performance.
Trailer towing not on ly places more stress on the
ve hicle, it also ca lls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
@ Note
If you are going to tow a trailer, you must ac­
tivate the tra ile r operation mode
¢ page 82, Operating instructions.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trai ler weight. The hitch must be suitab le
for your ve hicle and tra iler and must be mounted
securely on the vehicle 's chassis at a
technically
sound
locat ion . Use on ly a trailer hitch with a re­
movable ba ll mount . Always chec k w it h t he t rail ­
er hitch man ufactur er to make s ure t hat you a re
using the co rrect hi tc h.
Do not use a bumper hitch.
The hitch m ust be installed i n such a way that it
does not interfere with the impact -absorbing
bumper sys tem . N o mod ificat ions should be
made to the vehicle exhaust and b rake systems .
Fr om t ime to t ime, che ck t hat all hitch mo unti ng
bol ts rem ain securely faste ned.
W hen you are not tow ing a tra iler, remove the
tra ile r hitc h ba ll mount . This prevents the hitch
from ca using damage shou ld your veh icle be
s truck from behind¢ &..
82
Trailer brakes
If your trailer is equipped wi th a bra king sys tem,
c h ec k t o be sure that it con forms to all regu la ­
tions.
The trailer hydrau lic br ake system mus t not be
directly connecte d to the vehicle's hydr auli c
brake system .
Safety chains
Always use safety chains between your vehicle
a nd t he tra ile r.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check w ith your Aud i dea ler for correct wir ing,
switches and relays.
Mirrors
If you a re unab le to see the traffic behind you us­
i ng the regular outs ide mir rors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear.
A WARNING
Afte r remov ing the tra ile r hi tch, do not s to re
i t in yo ur vehicle. In cas e of sudden brak ing,
the hit ch could fly fo rwa rd and injure you or
your pas sengers.
Operating instructions
Maximum trailer weight
A tra ile r f or yo ur vehicle is lim ite d to a typical
cla ss 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trai ler is held sec urely in
place to p revent it from shifting forward , back­
ward or si deways .
Never allow a pas senger to ride in a trailer ¢ &.
in Driving instructions on page 84.
Engine cooling system
Towing a tra ile r makes the engine wor k harder . It
i s impo rtant that the cooling system's perform­
ance is up to the additional load. Ma ke sure that
the cooling system has enoug h fluid.

\.J ' Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the label
¢page 221. Inflate trailer
tires to trailer and tire manufacturers' specifica­
tions .
Lights
Check to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle. Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjusting the
tongue weight. The vehicle must be in
auto or
comfort driving mode and not raised
¢page 105, ¢0 .
Make sure that the vehicle is lowered. In Info­
tainment , select:
ICARI function button> Lower
control button.
If you must drive under poor road conditions , you
can raise the vehicle
after coupling the trailer or
after adjusting the tongue weight ¢page 107.
0 Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select
auto or comfort mode. Other­
wise, the tongue load specified for your ve­
hicle will no longer be applicable.
Trailer towing
Driving instructions
Driving with a trailer always requires extra care
and consideration .
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while keeping the trailer as light as possible under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
conditions are unfavorable -particularly when
going downhill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles.
Always apply brakes early . When driving down ­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Air suspension*
When driving with a trailer, activate the trailer
mode of the air suspension. Switch the air sus ­
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving . Select in the MMI:
I CAR ! function button > (Car)* systems control
button

Trailer towing
Coolant t emperatur e
The coolant temperatu re gauge <=? page 9 must
be observed ca refully. The coo lant tempe rature
can increase if you drive on long inclines in a low
gear at high engine sp eeds. Reduce your sp eed
immed ia te ly if the LEDs in the top part of the dis­
p lay turn on.
For more information abo ut indicator lights, re­

A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent . Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
Trailer towing information
Important to know
-
Your veh icle hand les different ly when tow ing a
tra ile r because of the additional weight and d if­
fe rent we ight d istr ib ution. Safety, performance
and economy w ill great ly depend o n how careful­
ly you load yo ur trailer and ope rate your r ig .
Before you actually tow your tra iler, practice
turn ing, stopp ing and bac king up in an area away
from t raff ic. Keep practicing until you have be­
come comple tely fami liar with t he way your vehi­
cle-trailer comb inat ion behaves and responds.
Backing up is d iffic ult and requires pract ice .
Backing up with a tra iler gene rally requires steer­
i n g ac tion oppos ite to tha t when backing up yo ur
veh icle w it h out a trailer .
M aintain a g reater d istance between your vehicle
and the one in front of you . You w ill need more
room to stop . To compensa te fo r th e tra ile r, you
will nee d a larger than no rma l tur ning rad ius.
When pass ing , remembe r that you ca nnot accel­
e rate as fast as you no rma lly would because of
the adde d load . Make s ure yo u have eno ugh room
to pass . After passing, allow plenty of room for
your trai ler before chang ing lanes again.

Assist Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay un­
der a specified maximum speed.
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 . (USA models)/ . (Canada models) indi­
cator light and a message appear in the instru­
ment cluster display at the same time. The./
• indicator light and the message turn off if the
speed falls back below the stored maximum
speed .
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
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
The warning threshold is set in the Infotainment
system.
.. Select: the
ICARI function button > (Car)* Sys­
tems control button > Driver assistance >

A WARNING
-Always pay attention to the traffic around
you when the cruise control system is in op­
eration . You are always responsible for your
speed and the distance between your vehi­
cle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy ra in and
hydroplaning), because this inc reases the
risk of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway exits
-
or in construction zones . ~

Ass is t
- Please note that unconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­ cause pressing the accelerator pedal over­
rides the cruise control system .
-If a brake system malfunction 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

What can the braking guard do ?
When detected in time, the system can assess
dange rous si tu at ions where an object ahead
brakes sudden ly or if yo ur own vehicle is trave ling
at a h igh speed and approach ing an ob ject that is
moving more slow ly. The braking guard does not
react if it cannot detect the situation.
The system advises you of var ious dange rous sit­
uations :
- The
di stan ce warning occu rs if you dr ive too
close ly to the object ahead fo r a long per iod of
time .
If the object ahead brakes strongly, you
would not be ab le to avoid a co llis ion. The .
indicator light appears as an indication for this .
- T he
appr oach w arning occurs when an object
ahead is trave ling more slowly or brakes
strongly. When this warning occurs, it may only
be possible to avoid a collis ion by swerving or
brak ing strongly . The danger is indicated by the
• indicator light
¢fig. 100 . An audio signal
w ill also so und .
If you do not react early enough or at all to a dan ­
gerous situation, the braking guard supports you
with a braking intervention .
- If a co llision is imminent, the system wi ll first
provide an
acute warning by braking sharply .
- If you do not react to th e acute warning, the
b raking guard can inc rease the braking force
w ith in the lim its of the system
1> . This reduces
the vehicle speed in the event of a coll is ion.
- T he system can in itiate complete dece leration
shortly before a collision
l) . Full deceleration at
high speeds occurs only in veh icles with adap­
tive cruise control and side assist (pre se nse
plus) .
- If the braking guard determ ines that you are
not braking s trongly enough when the re is a n
impending coll is ion, it can increas e the b raking
force.
- The p re sense funct io ns also engage w hen
there is an impending collision ~

Audi active lane assist
Description
Appl ies to: vehicles with Audi act ive lane assist
Active lane assist detects lane marker lines with­
i n the lim its of the system using a camera in the
windshield. If you are approach ing a detected
lane marker line and it appears like ly that you
will leave the lane, the system w ill warn you with
corrective steering. You can override this steering
at any time. If you pass over a line, the steering
whee l w ill vibrate lightly. In orde r fo r thi s warn­
i ng vibration to occ ur, it must first be switched
on in the Infotainment system. Active lane ass ist
is ready for operation when the lane marker line
is detected on at least one side of the vehicle.
The system is des igned for driving on express­
ways and highways and therefore on ly activates
at speeds above approximately 40 mph (65 km/
h) .
Applies to: vehicles with side assist
If you activate a turn s ignal when act ive lane as­
s ist is ready and it classifies a lane change as crit ­
ica l because of vehicles traveling a longside you or
approach ing you, there wi ll be noticeable correc­
tive steer ing shortly before you leave the lane.
This will attempt to keep your veh icle in the lane.
Applies to: vehicles without side assist
The system will not wa rn you befo re c ross ing a
l ane marke r line if you have act ivated the t urn
s ignal. In this case, it assumes that you are
changing lanes intentionally.

ASR red uces eng ine power when the drive w heels
be gin sp inning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler ­
ate and dr ive up h ills.
Electronic differential lock (EDL)
E DL a ppl ies the bra kes to a wheel tha t st art s
sp inning and tra nsfe rs t he dr ive powe r to t he
120
other driving whee ls. This func tion is no t ava ila ­
ble at hig her speeds.
I n extreme cases , EDL automat ic al ly swi tches off
to keep t he b rake o n the br aked wheel from ove r­
heating. The ve hicle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze th e vehicle by ch ang ing
t h e s teer ing torque.
I n veh icles with dynamic s teer ing*, ESC a lso
helps to stab ilize the s teeri ng in cr it ic al situ a­
tions.
Selective wheel torque control
Se lective wheel to rque control is used when d riv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both whe els on the i nside of th e
cu rve are braked se lectively as needed. This al­
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "a utomat ic post -coll is io n braking system"
can help to reduce the risk of sl iding and of addi­
tiona l co llisions after an acc iden t. If the a irbag
c on tro l modu le dete cts a collision above a cer tain
vehicle speed, the veh icle is braked by t he ESC.
The veh icle does not brake automatically if:
- the drive r presses the accelerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle elect ri­
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. Th is is es pec ially i mpo rtan t
on s lippery or we t roads. If the system s be­
g in a cting to s tabili ze yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let the inc reased safety provided tempt
