Side assist's detection area is designed to cover lanes of standard
width to the left and r ight of your travel lane, depend ing on whethe r
you drive in the center of your lane or c loser to the edge .
I f you drive in narrow lanes, side assist's detection area may also
include other lanes - especially if you tend to dr ive on the edge of
your
lane~ fig . 182. Under these conditions, vehicles can also be
de tec ted tha t are two lanes away, and side ass ist then c ould switch
between the informational and warning stage signa ls.
When d riving in very wide lanes, vehicles in t he adjacent lane may
not be detected because they are not ins ide the detection area. •

Audi side assis t : sy stem fault
Have t he system chec ked by an autho rized Audi dealer o r qualified
workshop. •
Applies to vehic les: with side assist
Safety tips
The side ass ist detec tion may be li mit ed when dr iv ing a round
narrow street corners, on hilly streets, and under poor weather
conditions.
I t is possible that the radar sensors may a ls o detec t other objects,
such as high or staggered guardrails.
Side ass ist does not measu re actual la ne w idth. 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 driv ing to the left or right of the center of a travel lane, it is
possible that vehicles wi ll be detected that are
not in the lane next
to the lane you are using.
& WARNING
• Improper relian ce on the side assi st system c an cau se colli ­
sions and serious personal injury:

___ A_ u_ d_ i_s _i_d _e_ a_ s_ s
_ is_ t __________________________________________________ _
&, WARNING (continued )
-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 a ssist cannot detect all vehicle s under all conditions ­
danger of a cc ident!
• 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
vi sion can be reduced or entirely blocked by
rain , snow , and heavy spray . This can result in side as sist not
adequately detecting vehicles or , in some cases , not dete cting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• 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 lea st 37 mph (60 km /h).
• Side assist signal does not work around tight corners (turning
radius less than 218 yards , or 200
ml.
• Side a ssist 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 .
0 Note
To ensure that s ide assist is not adv ers ely affected, you should not
b lock the area on the rea r bumper where the radar sensors are
located with for eign objects (such as wit h stickers or b icycle rac ks).
[ i ] Tips
If th e pos it ions of the rada r se nsors have bee n changed as a resu lt
of a rear end -collision, for instance, have side as sist checked by an
autho rized Aud i dea ler fo r sa fety reaso ns.•

& WARNING
• Unintended vehicle movement can cause seriou s injury .
- When the selector lever is in a driving position , the vehicle
may creep , even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move,
be cause power is tran smitted to the wheels as soon as a
driving position is engaged .
- Do not accelerate while select ing a driving position . At th is
time the engine must be at idle speed so that undue stress is
not placed on the clut ches in the transmi ssion .
- Remember: -even when stopped briefly with the automatic
transmission in
" D " or "R ", engine power is being transmitted
to the wheels . Your vehicle could "creep " forward or backward.
When stopped , keep the brake pedal fully depressed and use
the parking brake if necessary to keep the vehicle from rolling.
• If the selector lever is unintentionally moved into N while you
are driving , take your foot off the accelerator pedal and wait for
the engine to return to idle speed before sele cting a driving posi ­
tion.
• Never shift into
" R " or "P " when the vehicle is in mot ion .
• Never get out of the dri ver's seat when the engine is running .
• If you must get out of the vehicle , move the selector lever
securely into the P position and apply the parking brake firmly .
• If the engine must remain running , never have any driving posi ­
tion engaged when checking under the hood . Make sure the
selector lever has securely engaged and is locked in
"P" with the
parking brake firmly
