Adaptive Light
When making a turn or driving around tight corners, the
relevant area of the road is better illuminated.
Adaptive Light (making turns)
Fig. 60 Adaptive Light
when turning and
driving through curves
An additional bulb in the headlight provides a cornering light@ in
addition to the low beam @=> fig.
60. Adaptive Light is switched on
and off automatical ly depending on driving conditions .
When you activate the turn signal lever, the Adaptive Light for the
same side is switched on. Please note that the turn signal lever must
engage. Adaptive Light is not switched on if you only move the turn signal
lever to the point of resistance to signal a lane change =>
page 73,
"Turn signal¢ c:> and high beam 110 lever".
When driving around bends, Adaptive Light is controlled according
to steering wheel angle .
• It is switched on in tight corners .
• It is not switched on in long, open bends.
Adaptive Light (in curves)
When driving through curves , the low beams @are automatically
controlled depending on driving speed and the steering wheel
angle.
The two main beams pivot at different angles so that there is no
unilluminated area in front of the vehic le .
[ i J Tips
• The system works up to a speed of about 43 mph (70 km/h). If the
speed is higher, it is not activated .
• Adaptive Light (in curves) functions at a speed of about 6 mph
(10 km/h) and is deactivated at speeds below about 4 mph
(6 km/h). •

Audi lane assist
Lane assist
Applies to veh icles : with lane assist
Description
Lane a ssist helps you keep y our vehicle in your lane .
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver. If lane assist
detects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indica tor light /: on the instrument cluster .
I f the system is in active standby mode and the turn signal is acti­
vated before driving ov er the boundary line, the warning does not
occur since the sys tem allows for intenti onal lane changes.
The system is designed for driving on freeways and expanded high ­
ways and t hus works on ly at speeds of 40 mph (65 km/h) or mo re .
& WARNING
• Lane ass ist will not k eep your vehicle in your lane. The sy stem
only warns the d riv er w hen t he vehicle i s le av ing the lan e. The
driv er is alway s re spon sible for keeping the vehicle in the lane.
• The camera is not able to d ete ct all lane boundary lines and in
s o me cases might al so dete ct lane str ucture s or objects as
boundary lines . This c an le ad to in corre ct wa rning s or warnings
that fa il to go off at all .
• The camer a's visibili ty ca n be i mpaired by vehi cle s ahe ad of
you , for instan ce, or by rain , snow , h eavy spray or li ght shining into
th e cam era lens . Thi s can ca use lane as sis t to f ail to d ete ct

Description
The side assist helps you when changing lanes.
[ Audi AS J
Fig. 173 Rear bumper:
Position of radar
sensors (not visible on
outside)
Fig . 174 Signal light
on the outside mirror -
driver's side
Side assist uses radar sensors (not visible on outside) => fig. 173 to
help the driver check blind spots, and see what is happening in
traffic behind the vehicle =>
page 158, fig. 176.
Signal lights are built into both outside mirrors=> fig. 174. The
signal light on the left outside mirror assists when moving over into the left lane and the signal light on the right outside mirror assists
when moving over into the right
lane.
The signal light comes on to tell you that side assist has detected a
vehicle on that side and that the position of this other vehicle
should be taken into account if you were to change lanes. This is
called the
informational stage signal=> page 158. The informational
stage signal is designed so that you notice it only when you are
looking in the outside mirror .
When you activate the turn signal and side assist detects a vehicle in a notable location, the corresponding signal on the outside
mirror flashes briefly and brightly several times. This is the
alert
stage signal
=> page 158. •

T he system works at speeds faster than 19 mph (30 km/h) .
& WARNING
• Improper reliance on the side assist system can cause colli­
sions and seriou s per sonal injury:
- Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to c hange lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist 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 reduced or entirely blocked by
rain , snow, and heavy spray . This can result in side assist 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.
• Please note that side assi st indicates there are approaching
vehicles, or vehicles in your bl ind spot , only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km /h).
• S ide assist signal does not work around tight corners (turning
radiu s less than 328 feet or 100 m ).
• Side assist is no replacement for the driver's full attention . The
d river alone is responsible for lane changes and similar driv ing
maneuvers. Always keep an eye on the d ire ction you are travel ing
and the relevant area around the vehicle .

Sensor detection area
Fig. 176 Sc hem ati c
illu str ati on : Sens or
d etec tio n area
The detection ~ fig. 176 of the radar sensor detection area is made
up of:
• the approach area !light green area)
0, about 230 feet (70 ml
behind the veh icle, 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 travel lane, it is
possible that vehicles will be detected that are
not in the lane next
to the lane you are using~
page 163. •
Applies to vehicl es: with side assist
Operation
Side ass ist compares the distance and difference in speed of
detected vehicles with the speed of your vehicle. Whenever the
difference in speed and distance is registered as notab le 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 slowly (difference in speed less than 9 mph, or
15 km/h), the signal light will come on as soon as the other
vehicle is in your blind spot and is detected by side assist. When the
difference in speed is greater, the signa l light will not come on .•
Applies to vehic les : w ith side assist
Informational and alert stage signals
Side assist has two signal stages:
• the informational stage signal, and
• the alert stage signal.
Side assist helps you by using the appropriate signa l stage,
depend ing on whether or not you have act ivated the turn signal,
and thus have indicated that you are or are not changing lanes.
In fo rm ati onal stag e 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
vehic le's difference in speed and distance is registered by side
assist as notable, the signa l light on the respective mirror produces
muted il luminatio n.
The brightness of the informationa l stage signal 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. .,,,

___________________________________________________ A_u_ d_i_ s_ id_e_ a_ s_s _i_s _t _ __.1!111
When you look in the outside mirror, you can clea rly see the infor ­
mational s tage signal.
Ale rt sta ge signal
When you ac tivate the turn signal, and side assist has detected a
vehic le in a notab le location on that particu lar sid e, the signal light
on this side mirror flashes brightly. The repea ted brief and bright
flash ing of the aler t stage signa l reminds you to carefully check
t raffic to the rear in the outside mirror and over your shoulder, so
that you can safely complete the lane change=>
