A WARNING
Anyone not proper ly 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 vehicle handles differently when towing a
tra iler because of the additional weight and dif­
ferent weight distribut ion . Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopp ing and back ing up in an area away
from traff ic. Keep practicing until you have be­
come completely fam iliar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires pract ice.
Backing up with a trailer generally requires steer­
ing action opposite to that when backing up your
vehicle without a trailer.
Maintain a greater d istance between your vehicle
and the one in front of you. You w ill need more
r oom to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When passing, remember that you cannot accel­
erate as fast as you normally wou ld because of
the added load. Make s ure you have enough room
to pass. After passing, a llow plenty of room for
your tra iler before changing lanes again.
Trailer towing
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load
c::> page 259 .
Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
• Apply the foot brake.
• Have someone place chocks under both the ve­
hicle and the trailer wheels.
• With chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
• Turn the whee ls towards the curb.
• App ly the parking brake.
• Select the P selector lever position.
When restarting after parking:
• App ly the foot brake.
• Start the engine.
• Select the D/S se lector lever position.
• Release the parking brake and slowly pull out
and away from the wheel chocks.
• Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector lever of the automat­
i c transmission to P before applying the park­
i ng brake and before blocking the wheels, you
may have to use more force later to move the
l ever out of the P position.

" N .... 0 0 <..:l ' -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 switched on, the braking function in
the system may be switched off. The rest of
the cruise control system functions remain
active as long as the
(tj;(IM@ (USA models) /
ii (Canada models) indicator light is on.
@ Tips
The brake lights turn on when the brakes are
applied automat ically .
Changing speed

.. To increase or decrease the speed quickly, hold
the lever in the
G)/0 direction until the de­
sired speed is displayed.
You can also press the accelerator pedal down to
increase your speed, for example if you want to
pass someone. The speed you set earlier will re­
sume as soon as you release the accelerator ped­
al.
However, if you exceed your saved speed by 5
mph (10 km/h) for longer than 6 minutes, the
cruise control system turns off temporarily .
The green
ltj;(i )~i@ (USA models) 1 '11 (Canada mod­
els) indicator light in the speedometer turns off
and the stored speed is maintained.
Preselecting the speed

Audi adaptive cruise
control
Description
Applies to: vehicles with Audi adapt ive cruise control
F ig. 89 Detection range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the driver by both regulating the speed and
maintaining 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 cruise control do?
The adaptive cruise contro l system uses video, ra ­
dar and ultrasound . Objects driving ahead can be
recognized up to 650 feet (200 m) away.
On open roads with no traffic, it functions
like a
cruise control system . The stored speed is main­
tained. When approaching an object ahead, the
adaptive cruise control system automatically
brakes to match that object's speed and then
maintains t he stored distance . As soon as the
system does not detect an object ahead, adaptive
cru ise control acce lerates up to the stored speed .
In stop-and-go traffic, adaptive cru ise control can
brake until the vehicle is stat ionary and then be­
g in driving aga in under certain conditions
¢page 91.
Audi braking guard can warn you about an im­
pending collision and initiate braking maneuvers
¢page 93.
88
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 90, Switching on/off.
When driving, you can stop cruise control
¢page 92 or cha nge the speed ¢ page 91 at
any time.
You can also set the distance to the object mov­
ing ahead and set the driving mode of the adap ­
tive cruis e con trol
¢p age 92.
General information
Applies to: vehicles with Audi adaptive cruise control
Fig. 90 Front of the vehicle: sensors and video camera
The areas that contain the radar and ultrasonic
senso rs and the video camera ¢
fig. 90 must not
be covered by stickers, deposits or other objects
because they can interfere with the function of
the adapt ive cruise control system and braking
guard. For information on clea ning, refer to
¢ page 231. The same applies for any modif ica­
tions made in the front area.
The function of the adaptive cruise control sys­
tem and braking guard is limited under some
conditions.
- Objects can only be detected when they are
with in the sensor range
¢p age 88, fig. 89.
- Th e system has a limit ed ability to detect ob­
jects that are a sho rt distance ahead, off to the
side of your vehicle or moving into your lane.
- Objects that are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves¢
page 89. ll>

Ass is t
When driving into a curve ~ fig. 91 and out of a
curve, the adaptive cruise control may react to an
object in the neighbor ing lane and apply the
brakes. You can prevent that by pressing the ac­
celerator pedal brief ly .
Stationary objects
App lies to: vehicles with Audi adaptive cruise contro l
Fig . 92 Examp le: ob ject changin g lanes and stationary o b­
j ect
The adaptive cruise contro l system only reacts to
objects that are mov ing or that the system has
a lready detected as moving. For examp le, it can
react when a vehicle that has a lready been de ­
tected @turns or changes lanes, but adaptive
cru ise control does not react to a stat ionary vehi ­
cle @.

• Tap the switch to display the current set dis­
tance ¢
fig. 97.
• To increase or reduce the distance in incre­
ments, tap the sw itch again to the r ight or left .
The distance between the two veh icles will
change in the instrument cluster display .
When approaching an object ahead, the adaptive
c ruise contro l system brakes to match that speed
and then adjusts to the set distance.
If the object
ahead accelerates, adaptive cruise control will al­
so accelerate up to the stored speed .
The higher the speed, the greater the distance in
meters
~ &, . The Distance 3 setting is recom­
mended. That is equa l to the general recommen­
dation of "half the speed shown on the speedom­
eter" .
The distances provided are specified values . De­
pending on the driving situation and the way the
object ahead is driving, the actual distance may
be more or less than these target distances .

A WARNING
Following other vehicles too closely increases
the risk of coll isions and ser ious personal in­
jury.
- Setting short distances to the traffic ahead
reduces the t ime and distance available to
br ing your vehicle to a safe stop and makes
it even mo re necessary to pay close atten­
t ion to traffic.
- Always obey applicable traffic laws, use
good j udgment, and select a safe following
distance for the traffic, road and weather
condit ions .
@ Tips
- Di stance

Applies to: vehicles with Audi adaptive cruise control
F ig. 98 Instrument c luster: request for driver intervention
In certain situations, the system will request you
to take action:
- if the braking from the adaptive cruise control
system is not enough to maintain enough dis­
tance to the object ahead.
T he danger is indicated by the. indicator light
~ fig. 98. An aud io signa l will also sound.
- Press the brake pedal to slow your vehicle down.
Audi braking guard
Applies to: vehicles with Audi adaptive cruise control
Fig . 99 Instrument cluste r: approac h warning
The braking guard uses radar sensors and a v ideo
camera. It also f unctions w ith in t he lim its of the
system when adaptive cru ise control is switched
off.
What can the b raking guard d o?
When detected in time, the system can assess
dange rous situations where an object ahead
brakes sudden ly or if yo ur own vehicle is trave ling
at a high speed and approaching an object that is

Assist
moving more slowly. The braking guard does not
react if it cannot detect the situation.
The system advises you of various dangerous sit­
uations:
- The
distance warning occurs if you drive too
closely to the object ahead for a long period of
time . If the object ahead brakes strongly, you
would not be able to avoid a collision. The.
indicator light appears as an indication for this.
- The
approach warning occurs when an object
ahead is traveling more slowly or brakes
strongly . When this warning occurs, it may only
be possible to avoid a collision by swerving or
braking strongly. The danger is indicated by the
• indicator light ¢
fig. 99. An aud io signa l will
also sound.
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 collision is imminent, the system will first
provide an
acute warning by braking sharply.
- If you do not react to the acute warning, the
braking guard can increase the braking force
within the limits of the system
1l. Th is reduces
the vehicle speed in the event of a co llision.
- The system can initiate complete deceleration
shortly before a collision
ll. Full deceleration at
high speeds occurs only in vehicles with adap­
tive cruise control and s ide assist (pre sense
plus).
- If the braking guard determines that you are
not braking strongly enough when there is an
impen ding collision, it can increase the braking
force .
- The pre sense functions also engage when
there is an impending collision
¢ page 137.
Which functions can be controlled?
You can switch the braking guard and the dis­
tance/approach warning on or off in the Infotain­
ment system ¢

A WARNING ,_
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . The driver must
always intervene. The driver is always respon­
sible for braking at the correct time.
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
example when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
- Always remember that the radar sensor for
the braking guard works only within defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
promptly detected or may not be detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
(D Tips
-You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
t he risk of damage or injury.

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)
T he EDL applies the b rakes to a whee l t h at s tarts
sp inning and tra nsfe rs t he dr ive powe r to t he
o ther driving wheel or wheels (if the veh icle is
120
equipped with a ll w hee l drive*) . T h is f unction is
not avai lab le at higher 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
