\.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:

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.

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.

Parking on a slope
Do not park on a slope wi th a trailer . If it cannot
be avoided, do so only after doing the following:
When parking:
.,. App ly the foot bra ke .
.,. Have so meone p lace cho cks unde r bot h the ve­
hicle and the trailer w heels.
.,. With choc ks in place, slowly rele ase the brakes
until the w heel chocks abso rb the load .
.,. Turn th e whee ls towards the curb.
.,. App ly the par king b rake .
.,. Select the P se lecto r lever posit ion.
When restarting after parking:
.,. App ly the foot bra ke .
.,. Start the engine .
.,. Sele ct the D/S se lector l ever position.
.,. Re lease the par king brake and s low ly pull o ut
and away from the whee l chocks.
.,. Stop and have someone re trieve the wheel
chocks .
(D Tips
If you move the selector lever of the automat­
i c transmission to P befo re applying the park­
i ng brake and before blocking the whee ls, yo u
may have to use more force la ter to move the

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

Audi drive select (drive
settings)
Introduction
Drive select makes it possible to experience dif­
ferent types of vehicle settings in one vehicle.
The dr iver can select
Comfort , Au to a nd D ynamic
modes i n the Infota inment system to switch be­
tween , fo r example, a sporty and a comfo rtable
driving mode .
Sett ings can be ad justed to your personal p refe r­
e nces in
Ind ividual mode. Th is makes it poss ible
t o combine settings such as a sporty engine se t­
ting w ith light steering .
Description
The following systems, among other things, are
infl uenced by drive select :
Engine and automatic transmission
Depending on t he mode, the e ng in e and auto ­
mat ic transmission respond more q uick ly o r in a
more balanced manner to accelerator pedal
Assist
movements . In the sporty dynamic mode, the
transmission shifts at higher speed ranges.
Adapt ive a ir suspension *
The adapt ive ai r suspension* is an e lectron ically­
co ntro lled air suspens io n and dampi ng sys tem.
T he ad justmen t depends o n the dr iving mode se­
l ected, steering movements, the driver's braking
and acce le ration, and as the road surface, veh icle
speed and load.
T he vehicle groun d clearan ce depends on t he
mode selected and the speed . When you are in
the
auto , the highway setting is activated when
yo u drive above 75 mph (120 km/h) for more
than 30 seconds. The g round clearance is in­
creased automatically if the speed drops be low
44 mp h (70 km/h) for more than 120 seconds .
Suspension control*
With the Audi Dynamic Ride Control damping
contro l, dampening characteristics of the ve hicle
can be individually adjusted us ing drive select.
This makes it possible to satisfy the des ire for
sporty suspens ion
(DYNAMIC) and comfortable
s u spension (COMFOR T) without g iv ing up bal­
anced tu ning (AUTO) .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is espec ially
su ited to long drives on a highway . The Dynam ic
mode provides sporty, direct steering .
Applies to: vehicles with dynamic steering
The steering ratio changes based on veh icle
speed in order to maintain opt imum steer ing ef­
fort fo r th e driver at all times . Thi s sets the s teer­
i ng to be less sensitive at h igher speeds i n orde r
to provide improved ve hicl e con trol. At reduced
speeds, stee ring is more direct in orde r to keep
t h e s teer ing effort as minimal as possible when
t h e driver is maneuvering the ve hicle. At low and
average speeds, dynamic steering * additionally
provides more responsive steering performance.
Sport differential*
As a compone nt o f the all whee l dr ive system
(qua ttro)

Ass is t
depending on the s ituation. The distr ibution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high leve l of agility and ability to accel­
erate on curves. The veh icle is very responsive to
steer ing .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivot ing action and the lighting also adapt to
the mode.
Adaptive c ru ise contr ol*
The behavior when acce le rating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control a lso
responds to the driving behavior of the veh icle
ahead in a more conservative or sporty manner.
Engine sound *
The engine sound adapts to the current mode
and can be subtle to sporty .
(D Note
Applies to: vehicles with adaptive air suspension
- Make sure there is enough clearance above
and below the veh icle when parking. The
height of the vehicle (ground clearance) can
change once it is parked due to tempera ture
fluctuations, changes to the load condit ions
and c hanges to the d riving modes.
- When transporting the veh icle on a car car­
r ier, tra in, ship or by other means, only tie
the veh icle dow n at the running surfa ce of
the tires, w hic h is the outer circ umference .
Securing the vehicle at the axle compo ­
nents, suspension st ruts or towing eyes is
not permitted because the pressure in the
air suspension struts can change dur ing
transport . The vehicle may not be secured
sufficiently if this happens.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynam ic modes.
106
- The S se lector lever position a utomat ica lly
engages if the dynamic mode is selected.
- Applies to: vehicles with dynamic steering:
operating noise is heard when starting or
stopp ing the engine. Th is does not indicate
a problem.

Electronic Stabilization
Control (ESC)
Description
Elect ronic Stabilization Control (ESC) suppo rts
driver safety.
It red uces the risk of slipping and
improves dr iving stability. ESC detects crit ica l sit­
uations such as the veh icle oversteering and un­
dersteering or the wheels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
ing engine torque. As soon as the ESC is active ly
regulat ing, the
D.1 indicato r light blin ks in the in­
s trumen t clus ter.
The fo llow ing systems are integrated in the ESC :
Ant i-lock braking system (ABS)
ABS p revents the whee ls from locking whe n brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis­
tance . It increases brak ing power when the driver
presses the brake pedal q uick ly in emergency sit­
uations . You must press and hold t he b rake pedal
until the dangerous sit uat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle dr iv ing ahead is too small. On
ve hicl es with act ivated and f unct io ni ng night vi ­
sion assist*, the brake assist system can respond mo re sensit ively if there is a warning .
Anti-slip regulation (ASR)
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
