2018 AUDI A8 warning light

Assistance systems
-Please note that unconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­
cause pressing the accelerator pedal over­
rides the cruise control system.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off. The rest of
the cruise control system funct ions remain
active as long as the
@;\IM~ (USA models) /
l'I (Canada models) indicator light is on.

" N .... 0 0 :c ' What can the braking guard do?
When detected in time, the system can assess
dangerous sit uat ions where an object a head
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is
mov ing more slowly. The brak ing guard does not
react if it cannot detect the situation.
The system advises you of various dangero us sit­
uations :
- T he
distan ce warning occurs if you d rive too
closely to the object ahead for a long period o f
time . If the object ahead brakes strongly, you
would not be able to avoid a collision .
The.
indicator light appears as an indication for th is.
- The
app roach wa rning occurs when an object
ahead is traveling more s low ly or brakes
strongly. When th is warning occurs, it may on ly
be poss ible to avoid a co llision by swerving or
braking strongly . The danger is indicated by the
• ind icator light ¢ fig . 113 . An aud io signal
will a lso sound .
If you do not react early enough or at a ll to a dan­
ge rous situation, the braking guard suppo rts you
w ith a brak ing intervent ion . T he approach warn­
i ng indicators and the message
Braking guard :
e ngaged
also appea r.
- If a co llision is imminent, the system will first
provide a n
acute warning by braking sharply .
- If you do not react to the acute warning, the
brak ing guard can increase the braking force
withi n the l imits of the system . This reduces
the vehicle speed in the event of a co llision.
- T he system can init iate complete decelerat io n

high speeds occu rs on ly in vehicles with adap­
t ive cr uise con trol and s ide ass ist (pre sense

-If the bra king g uard determines tha t you are
not brak ing st rongly eno ugh when there is an
impending co llision, i t can increase the brak ing
force.

jam or vehicle that has broken down in traf ­
fic).
- Always remember that the radar sensor for
the brak ing guard works only within def ined
detection and range limits that may prevent
the proper detect ion of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Mov ing vehicles up ahead may not be
p romptly de tected or may no t be detected

Audi active lane assist
(lane departure assist)
Description
Applies to: vehicles with Audi active lane assist
Active lane ass ist detects lane marker lines with­
in the limits of the system us ing a came ra in t he
w indsh ie ld. If you are app roaching a de tected
l ane marker line and it appea rs likely t hat you
will leave the lane, the system wi ll warn you with
corrective steering. Yo u can override t his steering
at any time . If you pass over a line, the steer ing
wheel will v ibrate lightly. In order for this warn­
i n g vibration to occur, it must f irst be sw itched
on in the Infotainment system . Active lane assist
i s ready for operation whe n the lane marke r line
i s detected on at least one s ide of the vehicle .
The system is designed for driv ing on express­
ways and highways and therefore only activates
at speeds above approximate ly 40 mph (65 km/
h).
Applies to vehicles with side assist
If you activate a tur n signa l when active lane as­
sist is ready and it class ifies a la ne cha nge as cr it­
i cal because of ve hicles t raveli ng a longs ide you o r
approaching you, the re w ill be not iceab le correc­
tive stee rin g short ly before you leave t he lane.
This will attempt to keep yo ur vehicle in t he lane.
A ss istance systems
Applies to vehicles w it h out side assist
T he system wi ll not warn yo u before c ross ing a
l ane marker line if you have activated the t urn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
Appl ies to: vehicles with adaptive c ruise control
The co rrective steer ing is targeted based o n the
dr iv ing s itu ation . In add it ion to the lane mar ker
li nes, the system can al so t ake into accoun t other
objects s uch as gua rd rai ls. If they a re detected in
close proximity to t he vehicle, active lane assist
helps p reve nt the vehicle from driving too close
to them. The re is a lso pass ing ass istance. The
system does not provide any corrective steering if it detects that you are pass ing anot her vehicle .
A WARNING
-
-The system warns the drive r that the vehicle
is leaving the lane using corrective steering.
T he drive r is always responsible fo r keeping
the vehicle within the lane.
- T he system can assist the dr iver in keeping
the vehicle in the l ane, but it does not dr ive
by i tsel f. Always keep your hands on the
s teer ing whee l.
- Cor rec tive stee ring may not occur in cert ain
situa tions, such as during he avy b raking .
- T here may be cases whe re t he came ra does
not recogni ze all lane mar ker lines . Cor re c­
tive steering can only take pla ce on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structu res 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 rest ricted, for ex­
ample by vehicles driving ahead or by ra in,
snow, heavy spray or light shining into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines o r de­
tect ing them inco rrectly .
- Unde r ce rtain condit ions such as r uts in the
road, a ban ked roadway or crosswinds, the
correct ive steer ing alone may not be enough
to keep the vehicle in the middle of the lane.

sessing the traffic situation.
- Night vision assist can only warn about peo­
ple and wild animals located within the visu­
al range of the infrared camera. The visual
range corresponds to the image in the in­
strument cluster display .
- Night vision assist may not detect people or
wild animals and mark them if
- they are not in an upright position, for ex­
ample if they are sitting or lying down
and/or
- the silhouette in the display appears in­
complete or interrupted, for example be­
cause the person is partially covered by a
vehicle or an animal by tall grass . This
could increase the risk of an accident.
- Never try to swerve around animals if doing
so will endanger you or other road users, be­
cause this increases the risk of an accident.
