assist.
Setting the warning point Early:
With this setting, a warning is provided
before a wheel touches the detected lane
boundary line. The warning depends on the
angle in which the vehicle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you drive toward a boundary line at a very sharp angle, the warning will come just before
a wheel touches the line.
Medium: With this setting, the warning point
is adapted to the course of the road, the lane
width and the speed. You will still be warned
Audi lane assist 97
if you cross slightly over a dotted line when
driving on curves.
Late: This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel vibration can be set to
Low, Medium or Strong. Selecting each of the
settings will cause the steering wheel to vi­
brate so you can check the strength of the vi­
bration in that setting.
(D Tips
Your settings are automatically stored and
assigned to the remote control key being
used.

-The radar sensor's vision can be reduced
or entirely blocked by rain, snow, and
heavy spray . This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the d irection you
are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, o r vehi­
cles in your blind spot, only after your ve ­
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side ass ist signal does not work around
tight corners (turning radius less than
328 feet or 100 m).
- Side assist is no replacement for the driv­
er's full attention . The driver alone is re­
sponsible for lane changes and similar
driving maneuvers. A lways keep an eye
on the direction you are traveling and the
relevant area around the vehicle.
(D Note
- To ensure that you do not adversely af­
fect side assist, do not block the area on
the rear bumper where the radar sensors
are located with foreign objec ts (such as
stickers or bicycle racks).
- Make sure that the signal light on the
outside m irror is not blocked by st ickers
or other items .
@ Tips
-Side assist automatically deactivates if it
detects that the radar sensors are
blocked ~
page 104. The indicator light
on the button goes out .
- The area on the bumper where the radar
senso rs are located must consistently re­
main free of snow, ice, and heavy soiling
so that side assist can function properly.
Follow the additional notes on
.:!>page 104 .
-Additional tinting on the front side win­
dows can make it harder to see and cor­
rectly understand the signa l light on the
outside mirror.

Sensor detection area
Applies to vehicles: with side assist
t
Fig. 102 Sc hemat ic illu st ration : Sen sor detect io n area
The detection ¢ fig. 102 of the radar sensor
detection area is made up of:
- the approach area (light green area)@,
about 230 feet (70 m) beh ind the veh icle,
and
- the "b lind spot" (dark green area) @.
The radar sensors cover the adjacent left and right lanes. Other lanes are
not covered by the
radar sensors .
(D Tips
Side assist does not measure actual lane
width. The system assumes a fixed lane
width . Detection in the left and right lanes
i s based on this assumed lane width .
When dr iv ing on narrow roads or when
driving to the left or right of the center of
a travel lane, it is possib le that vehicles
will be detected that are
not in the lane
next to the lane you are using
.:!> page 103.
Operation
App lies to vehicles: with side assist
Side assist compares the distance and differ­
ence in speed of detected vehicles with the
speed of your vehicle . Whenever the d iffer­
ence in speed and distance is registered as no­
table if you were to change lanes, a signal
light appears on the respective m irror. ..,.

MMI settings
Applies to vehicles: with side assist
The basic brightness setting of the signal on
the outside mirror can be adjusted via the
MMI.
~ Select: ICARI function button> Car systems
control button > Driver assist > Audi side
assist.
The brightness of the signal light for both the informational and alert stages is automatical­
ly adjusted to ambient light conditions. In ad­
dition, you can adjust the
basic brightness
separately, via the brightness function .
While making the adjustment, the new brightness setting is displayed briefly . The
brightness displayed is that of the informa­
tional stage signal. The alert stage signal
brightness is linked to the informational stage
signal brightness.
The informational stage signal brightness
should be adjusted so that you notice the sig­
nal illumination when you look in the outside
mirror, but not when you look forward
through the windshield .
In very dark or light surroundings, the auto­
matic brightness setting adjusts signal light
brightness to maximum or minimum intensi­
ty, as needed. In circumstances such as these,
you may not notice any change in the bright­
ness on the outside mirror when adjusting the
basic brightness. You may not notice the
change until lighting conditions are normal
again.
(D Tips
- Side assist is not active when the basic
brightness is adjusted. The signal light
comes on briefly to help you make the
adjustment .
- Your settings are automatically stored
and assigned to the remote control key
being used.

General information
Applies to vehicles: wit h side assist
Side assist has limits and cannot detect vehi­
cles under all road and weather conditions.
Please remember system limitations and nev­
er rely on the system, especially when :
- driving through curves
~page 103,
-lanes are of different widths ¢ page 103.
When driving through curves
Applies to vehicles: wit h side assist
Side assist cannot detect vehicles in curves
with a turning radius of less than 328 feet
(100 m).
When driving through a curve, it is possible
that side assist may register a vehicle two
lanes over, and the signal on the outside mir­
ror will light up.
Lane width

right of your travel lane, depending on wheth­
er you drive in the center of your lane or closer
to the edge.
If you drive in narrow lanes, s ide ass ist's de­
tection a rea may a lso include other lanes -es­
pecia lly if you tend to drive on the edge of
your lane¢
fig. 108. Under these cond it ions ,
vehicles can also be detected that are two lanes away, and side assist then could switch
between the informat ional and warn ing stage
signals .
When driving in very w ide lanes, vehicles in
the adjacent lane may not be detected be­
cause they are not inside the detection area.
Notes
Messages in instrument cluster display
Applies to vehicles: with side assis t
If side assist turns off automatically, the indi­
cator light on the button wi ll go out and you
will see a message in the instrument cluster

blocked
The side assist sensors are built into the rear
bumper on the left and right (not visible on
the outside)
¢ page 98, fig. 99 . To ensure that
you do not adversely affect the way side assist
functions, foreign objects (such as stickers or
b icycle racks) should not be attached to the
a rea on the rear bumper where the sensors
are located. If side assist functions are ad­
ve rsely affected, you will see this message in
the instrument cluster display. Remove any ­
thing that may be blocking the sensors .
If no vehicl e is detected for a longer period of
time while driving, side assist will also switc h
off a utomatica lly.
Audi side assist currently not available
If there is a temporary problem (such as the
ve hicl e's battery charge being low), s ide ass ist
cannot be activated tempo rari ly.
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Audi side assist: not available when
towing
The radar senso r's view is limited when tow ­
ing a trai le r. F or vehicles with a factory instal­
l ed towing hitch or a trailer hitch that was in­
sta lled later according to factory specifica­
tions, side assist is automatically deactivated as soon as the electrical connection to the
trailer's electrical socket is made, and this sta­
tus message appears in the instrument clus ­
ter display . Deactivation cannot be guaran­
teed when using a retrofitted towing hitch
that was
not installed acco rding to facto ry
specifications.
Safety tips
Appl ies to vehicles : wi th side assist
The side assist detection may be limited when
driv ing aro und narrow street corners, on hilly
streets, and under poor weather cond itions.
It is possible that the radar sensors may also
detect other objects, such as high or stag­
gered guardrails .
Side assist does not measure actual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
o n this ass umed lane width . When driving on
narrow roads or when driv ing to the left or
right of the center of a trave l lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using.
A WARNING
- Improper reliance on the side assist sys­
tem can cause collis ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes .
- Always check rear view mirrors to make
sure that it is sa fe to change lanes.
- Side assist cannot detect all vehicles un-
der all conditions- danger of accident! ..,.

Automatic car wash
The vehicl e can b e washed in almost any
modern automatic car wash .
The vehicle paint is so durable that t he vehicle
can n ormally be washed without p roblems in
a n automatic car wash . H owever, the effect on
the paint depends to a large extent on the de­
sig n of the fac ility, the filte ring of the wash
water, the type of wash and care mater ial , etc.
If the pa int h as a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a ca r wash, be s ure to
take the usual precautions such as clos ing the
windows and power roof. Factor y installed an­
tennas m ust not be removed.
If yo u have installed additional accessor ies on
the vehicle -such as spoilers, roof rack, etc. -
it is best to ask the car was h operator if these
should be removed .
When driv ing through an automatic ca r wash,
firs t se lect the
N posit ion and then sw itch the
engine off. If you switch the eng ine off when
N is engaged, the transmission remains in N
for approximate ly 30 m inutes and then Pis
engaged.

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo ­
ry ." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

250 Tires and wheels
contribution to good road ho lding and safe
handling when in good condition and properly
inflated
¢ ,& .
We recommend that all work on tires and
wheels be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about technical requ irements for
installing or changing tires and r ims.
Replacing tires and wheels
Tires shou ld be rep laced at least in pairs and
not individually (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system*
¢page 256.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement tires
must always have the same load rating speci­
fication as the original equipment or approved optional tires listed in the table
¢page 242.
Audi-approved specification t ires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving characteristics, and safety of the
vehicle. The table(¢
page 242) lists specifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure label located on driver's side
B-pillar (
¢ page 242, fig. 185) lists the speci­
fications of the orig inal equipment tires in­
stalled on your veh icle at the time it was man­
ufactured.
Federal law requires tir e manufacturers to
place standard ized information on the s ide­
wall of all tires¢
fig. 188 . This information
identifies and describes the fundamental
characterist ics, the quality grade of the tire
and also provides a tire ident ificat ion number for
safety standard ce rtification and in case of
a reca ll.
Tire specifications
Knowledge of tire specificat ions makes it eas­
ier to choose the correct tires. Radial tires
have the tire specifications marked on the
sidewa ll, for examp le:
255/45 R 19 104 H
This conta ins the following information:
P Indicates the t ire is for passenger cars
(where app licab le)
255 Nominal tire width in mm of the tire
from sidewall edge to sidewa ll edge. In
general, the larger the number, the wider
the tire
45 Height/w idth ratio in percent (aspect ra-
t io)
R Tire construction: Radial
19 Rim diameter code (in inches)
104 Loa d rating code
H Speed rat ing letter code
XL (or "xl", "EXTRA LOAD" or "RF") indicates
that the tir e is a "Reinforced" or an "Ext ra
Load" tire
M+S (or "M/S") Indicates that the tire has
some mud and snow capability
The tires could also have the information of
direction of rotation¢
page 238 .
Tire manufacturing date
The manufacturing date is also indicated on
the tire sidewall (possibly on ly on the
inner
side of the wheel):
"DOT ... 2211. .. " means, for example, the tire
was produced in the 22nd week of 2011.
Speed rating (letter code)
The speed rating letter code on the whee ls in­
dicates the maximum permissible road speeds
