-When not in use, to reduce fuel consumption,
wind noise and to guard against th eft.
A WARNING
- Use of an unapproved roof rack or incorrect
mounting of an approved roof rack can
cause the roof rack or the items attached to
it to fall off the roof onto the road.
- Objects falling from the roof of a vehicle can
cause a crash and personal injury.
- Only mount the roof rack on the designated
locations on the roof
c::> fig . 77.
- The roof rack system must be installed ex­
actly according to the instructions provided.
- When driving with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle handling
and lead to a collision . Always adapt your
driving and your speed to the current condi­
tions.
@ Note
- Your vehicle warranty does not cover any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Audi for your vehicle. The same applies to
damage resulting from incorrect roof rack installation .
-Always check the roof rack mountings and
hardware before each trip and during a trip
to make sure everything is securely tight­
ened. If necessary, retighten the mountings
and check the entire system from time to
time.
- After mounting a roof rack system, or when
you transport objects on the roof of your ve­ hicle, the height of the vehicle is naturally
increased. Be careful when driving under
low bridges or in parking garages for exam­
ple. This could cause damage to the load
and even the vehicle itself .
- Make sure the open rear lid and the sun­
roof* do not come into contact with the roof
rack .
Seats and storage
Loading the roof rack
Always distribute loads evenly. Make sure any­
thing on the roof rack is securely tied down .
.,. Always dist ribute the loads on the roof rack
evenly.
.,. Always attach items to the roof rack securely
before you drive off .
The maximum permissible roof weight is
220 lb
(100
kg) . The roof weight is the total of the
weight of the roof rack, the attachments and the
cargo you are carrying . You must also not exceed
the maximum load weight for the roof rack you
are using.
When using a roof rack system which has a lower
load carrying capacity, you must not use up the
total maximum permissible load carrying capaci­
ty specified above. Instead, you should load the
roof rack system only to the maximum capacity
specified by the manufacturer of the roof rack
system.
.&_ WARNING
=
Weak, damaged or improper straps used to
secure items to the roof rack can fail during
hard braking or in a collision and cause seri­
ous personal injury .
- Make sure the roof rack is installed exactly
as specified above
c::> page 70 .
-Always use suitable mounting straps for se­
curing items to the roof rack to help prevent
items from shifting or flying forward.
- Items on the roof rack must always be se­
curely mounted.
- The use of a roof rack can negatively affect
the way a vehicle handles . Cargo that is
large, heavy, bulky, long or flat will have a
greater negative influence on the vehicle's
aerodynamics, center of gravity and overall handling. Always drive slowly, avoid sudden
braking and maneuvers when transporting
cargo on the roof of your vehicle.
- Never exceed the maximum permissible
load carrying capacity of the roof of your ve­
hicle, the permissible axle weights and the
permissible total weight of your vehicle

Driving
Speed warning system
Introduction
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 .
You will hear a warning tone when your speed ex ­
ceeds the stored value by approximately 3 mph
(3 km/h). An indicator light . (USA models) .
(Canada models) in the instrument cluster dis­
p lay also tur ns on at the same time. The indicator
light •• turns off when the speed decreases
be low the stored maximum speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certa in
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.
(D Tips
Even though your vehicle is equipped with a
speed warning system, you should still watch
the speedometer to make sure you are not
driving faster than the speed limit.
Setting the threshold
You con set, change and delete the threshold in
the MMI.
.,. Select:
ICARI function button > Car systems
contro l button > Driver assist > Speed warning.
You can set any threshold between 20 mph (30
km/h) and 150 mph (240 km/h). Settings can
each be adjusted in increments of S mph (10 km/
h).

control
Description
A pplies to: ve hicles w ith Aud i adapt ive cruise co ntro l
F ig. 99 Detection range
What can adaptive cruise control do?
The adaptive cruise control system uses video, ra­
dar and ultrasound . Moving vehicles ahead can
be recognized up to about 650 feet (200 m)
away .
On open roads with no traffic, adaptive cru ise
control works like a regular cruise control sys­
tem. The stored speed is ma inta ined. When ap­
proaching a moving vehicle detected up ahead,
the adaptive cruise cont rol system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­ ously stored. As soon as the system does not de­
tect a vehicle up ahead, adaptive cruise control
accelerates back up to the stored speed.
In stop-and-go traffic, adaptive cruise control can
brake until the vehicle stops and accelerate again
under certain conditions and if this is possible
within the system's limits and capabilities
¢ page 94 . Adaptive cruise control will not
make an emergency stop .
Which functions can be controlled?
When you switch adaptive cruise control on, you
can set the current speed as the "control speed"
¢ page 92, Switching on and off.
When driving, you can stop cruise control
¢ page 94 or change the speed ¢ page 93 at
any time.

.&_ WARNING
Following other vehicles too closely increases
the risk of col lisions and ser ious personal in­
jury.
- Setting short distances to the traffic ahead
reduces the t ime and distance available to
bring your vehicle to a safe stop and makes
it even more necessary to pay close atten­
tion to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe following
distance fo r the traffic, road and weather
con ditions.

Audi active lane assist Lane assist
Description
Applies to: veh icles with act ive lane assist
Active lane assist helps you keep your vehicle in
your lane .
Active lane assist detects lane marker lines with­
in the limits
of the system using a camera in the
windshield. If you are approaching a detected lane marker line and it appears likely that you
will leave the lane , the system will warn you by
means of correct ive steering . T he dr iver can over­
ride the correct ive steering at any time. If the ve­
h icle crosses a line, the drive r is also warned by a
light
vibration in the steering wheel. The vibra­
tion warning must be switched on in the MMI for
this to happen. Active lane assist is operable
when the line marking the lane is detected on at
least one side of the vehicle.
The system is designed for driv ing on freeways
and expanded highways and thus works only at
speeds of 40 mph (65 km/h) or more.
Applies to vehicles with side assist* : If you acti ­
vate your turn signal when active lane assist is
ready and when activated side assist has class i­
fied a lane change as critical because of vehicles
traveling alongside you or coming closer, there
will be noticeable corrective steering just before
you leave the lane . Th is is done to try to keep
your veh icle in the lane .
Applies to vehicles without side assist*: when the
system is ready, it does not warn you if you acti ­
vate your turn signal before driving across a lane marker line. In th is case, it assumes that you are
changing lanes intent ionally.
If the vehicle is also equipped with Audi adaptive
cru ise control*, the corrective steering w ill be
more spec ific in regard to the driving situation .
I n addition to the lane marker lines, the system
can also take into acco unt other objects such as
guard rai ls. If they are detected in close prox imi­
ty to the vehicle, Audi active lane assist helps
prevent the vehicle from driv ing too close to
them. There is also passing assistance . The sys-
Audi act ive lane ass ist
tern does not provide any corrective steering if it
detects that you are passing another vehicle .
A WARNING
--The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can assist the dr iver in keeping
the vehicle in the lane, but it does not steer
by itself . Always keep your hands on the
steer ing wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
- The camera does not recognize all lane
marker lines. Correct ive steering can only
take place on the side of the vehicle where
lane marker lines are detected.
- Other road structures or objects could poss i­
b ly be identified un intentionally as lane
marker lines. As a result, co rrective steering
may be unexpected or may not occ ur.
- The camera view can be restricted, for ex­
ample
by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. This can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- Unde r certain condit ions such as r uts in the
road, a banked roadway or crosswinds, the
correct ive steer ing alone may not be enough
to keep the vehicle in the lane.
- For safety reasons, active lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
potential for hydrop lan ing . Using active lane
assist u nder these condit ions may i ncrease
the risk of a crash.

not adjacent to your cu rrent lane.
- if you are dr iv ing through a curve. Si de assist
may react to a vehicle that is one lane over
from the adjacent lane.
- if side assist reacts to ot her objects (such as

Audi side assist
-Improper reliance on the side assist system
can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly . The display may not
turn on in time .
- in poor weather conditions such as heavy
rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface . Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody . This can affect the system . Have
your authorized Audi dealer or authorized
Audi Service Facility check their function.
(D Tips
-If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be misin­
terpreted.

Introduction
Aud i drive select makes it possib le to experience
d ifferent types of veh icle sett ings in one veh icle.
The driver ca n select three
Comf ort, Aut o and
Dyn am ic modes in the MMI to switch between a
sporty and a comfortable driving mode.
You can a lso adjust the setting accord ing to your
p references in the
indi vidual mode. For example,
you can combine settings such as a sporty engine tuning with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and serious
personal injury.
Description
-
The follow ing systems are affected by drive se­
lect:
Engine and t ransm is sion
Depending on the mode, the engine and the
transmission respond quicker or in a more ba l­
anced manner to accelerator pedal movements.
In the sporty dynamic mode, the transmission
shifts at h igher RPMs.
Air suspe nsion
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
electronically controlled air suspens ion and
damping system . They are adjusted depending
on the se lected dr iving mode, the driver's steer­
ing, b raking and acceleration input and the road
surface, vehicle speed and load. A spo rty setting
is gene rally used in veh icles with adaptive air sus­
pens ion sport*.
The vehicle clearance va ries depending on these­
lected mode and the speed .
The highway setting is activated automatically
when yo u drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
au to or dynamic
106
mode. The ground clea rance is increased auto ­
matically if the speed drops below 44 mph (70
km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering rat ios. Indirect stee ring that moves
easily, like the steering in com fort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering .
The following app lies to veh icles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the dr iver at a ll times . This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, however, steering is more d irect in order to keep t he steering effort as
min imal as possible whe n the dr iver is maneuve r­
i ng the vehicle. A t low and ave rage speeds, dy­
namic steeri ng addit ionally prov ides more re ­
spons ive steering performance.
Sport differential*
As a component of the all whee l dr ive sys tem
(quattro)
~ page 195, the Sport differe ntia l*
dist ributes t he d riving powe r to the rear axle de ­
pend ing on the s ituation. The distr ib ution of
power va ries depending on the selected mode,
from ba lanced (comfort) to agile (dynamic). The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.
Cur ve light *
The curve light adapts to driving on curves . The
pivoting action and the lighting are also adapted
to the mode.
Adapt ive cruise control*
The behavio r whe n accelerating ca n be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise contro l also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner . ..,_
