d etec tion area
The detection => fig . 147 of the radar sensor detection area is made
up of:
• the approach area (light green area)
0, about 230 feet (70 m)
behind the vehic le, and
• the "blind spot" (dark green areal@.
The radar sensors cover the adjacent left and right lanes. Other
lanes are
not covered by the radar sensors.
[ i ] Tip s
Side assist does not measure actual lane width. The system
assumes a fixed lane width . Detection in the left and right lanes is
based on this assumed lane width . When driving on narrow roads or
when driving to the left or right of the center of a trave l lane, it is
possible that vehicles will be detected that are
not in the lane next
t o the lane you are using=>

Operation
Side assist compares the distance and difference in speed of
detected vehic les with the speed of your vehic le. Whenever the
difference in speed a nd distance is registered as notable if you were
to change lanes , a signal light appears on the respective mirror .
The signal can light up if you are passed by a vehicle or if you are passing another vehicle.
If you pass another vehicle slow ly (difference in speed less than 9
mph, or
15 km/h), the signal light wil l come on as soon as the o ther
vehic le is in your b lind spot and is detected by side assist. When the
difference in speed is greater, the signal light will not come on .•

Informational and alert stage signals
Side assist has two signal stages:
• t he informational stage s igna l, and
• the alert stage signal.
Side assist helps you by using the appropriate signa l stage,
depending on whether or not you have activated the tu rn signal,
and thus have indicated that you are or are not changing lanes .
Infor mation al stage signal
As long as you have not activated the turn signa l, side assist informs
you of detected vehicles that are registered as being in a notable location if you were to change lanes. Whenever the detected
vehicle's difference in speed and distance is registered by side assist as notable, the signal light on the respective mirror produces
muted illumination.
The brightness of the informational stage signa l is designed not to
be as intense, so that it does not interfere with your view of the road
when you are driving and have no intention of changing lanes. .,

Setting the signal brightness on the outside
mirror
The signal brightness can be set in the radio or MM/*.
Fig. 152 MMI Display:
Adjusting sign al
brigh tness
- Select: Function button [CARI> Audi side assist
=> fig. 152.
- Rotate the cont ro l knob to adjust the displayed bright-
ness of the signal light on the outside mirrors .
The brightness of the signal light for both the informationa l and
alert stages is automatica lly adjusted to ambient light conditions. In
addition, you can adjust the
basic brightness separately, via the
brightness function
=> fig . 152.
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 signa l brightness is linked to the
informational stage signal brightness .
Controls and equip ­
ment
The informational stage signal brightness should be adjusted so
that you notice the signa l illumination when you look in the outside
mirror, but not when you look forward through the windshield.
In very dark or light surroundings, the automatic brightness setting
adjusts signal ligh t brightness to maximum or minimum intensity,
as needed . In circumstances such as these, you may not notice any
change in the brigh tness on the outside mirror when adjusting the
basic brightness.
You may not notice the change until lighting conditions are normal
again.
[ i ] 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
Side assist has limits and cannot detect vehicles under a ll road and
weather conditions . Please remember system limitat ions and never
re ly on the system, especially when:
• driving through curves=>
page 141,
• lanes are of different widths=> page 142. •
Applies to veh ic les : with s ide ass ist
When driving through curves
Side assist cannot detect vehic les in curves with a turning radius of
less than 328 feet (100 ml. .,,
I • •

• .___A_ u_ d_ i_s_ i_ d _e_ a_ s_ s_is _ t __________________________________________________ _
When driving through a curve, it is possible that side assist may
register a vehicle two lanes over, and the signal on the outside
mirror will light up.•
Applies to veh icles: with side assist
Lane width
Fig. 153 Lanes of a
normal width are in
detection area
Fig. 154 Narrow lanes :
Side assist may detect
vehicles two lanes
away
Side assist's detection area is designed to cover lanes of standard
width to the left and right of your travel lane, depending on whether
you drive in the center of your lane or closer to the edge.
If you drive in narrow lanes, side assist's detection area may also
include other lanes -especially if you tend to drive on the edge of
your lane=> fig. 154. Under these conditions, vehicles can also be detected that are two
lanes away, and side assist then could switch
between the informational and warning stage signals.
When driving in very wide lanes, vehicles in the adjacent lane may
not be detected because they are not inside the detection area. •
Notes
Applies to vehicles: with side assist
Messages in instrument cluster display
If side assist turns off automatically, the indicator light on the
button will go out and you will see a message in the instrument
cluster display:
Audi side assist not available : sensors possibly blocked
The side assist sensors are built into the rear bumper on the left and
right (not visible on the outside)=? page 135, fig, 144. To ensure that
you do not adversely affect the way side assist functions, foreign
objects (such as stickers or bicycle racks) should not be attached to
the area on the rear bumper where the sensors are located. If side
assist functions are adversely affected, you will see this message in
the instrument cluster display. Remove anything that may be
blocking the sensors.
I f no vehicle is detected for a longer period of time while driving,
side assist will also switch off automatically.
Audi side assist currently not available
If there is a temporary problem (such as the vehicle's battery charge
being low), side assist cannot be activated temporarily.
Audi side assist: system fault
Have the system checked by an authorized Audi dealer or qualified
workshop. •

Safety tips
The side ass ist detec tion may be l imited w hen d riv ing ar ound
narrow street corners, on hi lly streets, and under poor weather
co nd ition s.
I t is possible that the radar sensors may also detect other objects,
suc h as high o r stagge red guardra ils .
S ide ass ist does not meas ure ac tua l la ne widt h. The syste m
assumes a fi xed lane width . Detection in the left and right lanes is
b ased on this assu med lan e wid th. Whe n driv in g o n na rro w roa ds or
when driving to the left or r ight of the c enter of a trave l lane, it is
po ssi ble that ve hic le s will be detec te d tha t are
no t in th e lane next
to the lane you are using .
& WARNING
• Improper reliance on the side assist system can cause colli ­
sions and serious personal injury:
-Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to change lanes .
• Side assist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly.
• The radar sensor's
vision can be redu ced or entirely blocked by
rain, snow , and heavy spray . This can result in side assi st not
adequately detecting veh icles or , in some cases , not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
Controls and equip ­
ment
& WARNING (continued )
• 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 130 km/h).
• Side assist signal does not work around tight corners (turning
radius less than 328 feet, or 100 ml. • S ide assist is no replacement for the driver' s full attention. The
driver alone is responsible for lane changes and similar driving
maneuvers . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
(D Note
To ensu re that side assist is not adversely affected , you sho uld not
b lock the area on the rear bumper where t he radar s ensors are
located with foreign objects (such as with stickers or bicycle racks) .

The tires and rims are essential parts of the vehicle's design . The
tires and rims approved by Audi are specially matched to the char ­
acteristics of the vehicle and can make a major contribution to good
road holding and safe handling when in good condition and prop ­
erly 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 special tools and spare parts as
well as the proper facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech­
nical requirements for installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced 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 moni ­
toring system* =>
page 301.
Always buy replacement radial tires that have the same specifica­
tions as the tires approved for your vehicle by Audi. Replacement
tires must always have the same load rating specification as the
original equipment or approved optional tires listed in the table
=> page 291. ~
