Audi active Lane assist
Active Lane assist
Description
Applies to vehicles: with active lane assist
Active lane assist helps you keep your vehicle
in your lane.
Active lane assist detects lane marker lines
within the limits of the system using a camera in the windshield . If you are approaching a de­
tected lane marker line and it appears likely
that you w ill leave the lane, the system will
warn you by means of corrective steer ing . T he
driver can over ride the cor re ct ive steer ing at
any time. If the veh icle crosses a line, the d riv­
er is also warned by a light
vibration in the
steering whee l. The vibration warning must
be switched on in the MMI for this to happen.
Active lane ass ist is operable when the line
marking the lane is detected on at least one
side of the vehicle .
The system is designed for driv ing on free ­
ways and expanded highways and thus works only at speeds of 40 mph (65 km/h) or more .
Applies to vehicles with side assist* : If you ac­
tivate your turn s ignal when active lane assist
is ready and when activated side assist has
classified a lane change as crit ica l because of
vehicles traveling alongside you or comi ng
closer, there will be noticeable correct ive
steer ing just before you leave the lane . This is
done to try to keep your veh icle in the lane.
Applies to vehicles w ithout s ide ass ist*: when
the system is ready, it does not warn you if
you act ivate your turn signa l before driving
across a lane marker line . In this case, it as­
sume s that yo u are ch ang ing lanes intent ion­
a lly.
I f the vehicle is also equipped with Audi adap­
tive cruise cont ro l*, the co rrec tive steering
will be mo re specific in rega rd to the driving
situation. In addition to the lane marker lines,
the system can a lso take into account other
objects such as guard rails . If they are detect­
ed in close proximity to the veh ic le, Audi ac-
Audi acti ve lane a ssis t 10 1
tive lane assist he lps prevent the vehicle from
driving too close to them. There is a lso pass­
ing ass istance . The system does not provide
any correct ive steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the drive r that the ve­
hicle is leaving the lane using co rrect ive
s teer ing . The d river is always r esponsible
for keeping the vehicle withi n the lane.
- The system can assist the dr iver in keep­
i n g the vehicle in the lane, but it does
not steer by itself. A lway s keep yo ur
h a nds on the steering wheel.
- Cor rective s teer ing may not occur in cer­
tain sit uat ions, such as dur ing heavy
bra king.
- Th e camera does not recogni ze all lane
marker lines. Cor rective s teer ing ca n only
take p lace on the side of the vehi cle
where lane marke r lines are detected.
- Othe r road str uctures o r objects co uld
possibly be identified unintentiona lly as
lane ma rker lines . As a res ult, corrective
steering may be unexpected or may not
occ ur.
- The camera view can be restricted, for
examp le by vehicles driving ahead or by
ra in, snow, heavy spray or light shining
into the camera . Th is can result in act ive
lane assis t not detecti ng the lane marke r
lines or detect ing them inco rrectly.
- Unde r ce rtain conditions such as ruts in
the road, a banked roadway or cross­
winds, the co rrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
m ust not be u sed w hen the re a re poor
road and/or weat her condi tions such as
slippe ry roads, fog, grave l, heavy rain,
snow an d the potential for hydroplaning .
Using active lane assist under these con­
ditions may increase the risk of a crash.

ically, the i nstrument cluster ind icator goes
out and one of the fo llow ing messages ap­
pears on the display :
Audi active lane a ssist : Curr ently un availa­
bl e. No camera view
This message appears if the camera is no lon­
ger funct ional after the system has cont inous­
ly failed to detect the lane markings . This
could happen if :
- The camera field of view¢
page 102,
fig. 108 is dirty or covered in ice. Clean the
area on the w indshield .
- The camera field of view is fogged over. Wait
until the fog has cleared before switching
active lane assist on .
- The system has been unable to detect the
lanes for an extended period of time due to
road cond it ions . Switch active lane ass ist
back on when the lines are more visible .

Pedestrian and wild animal detection depends
on the difference in temperature between the person/wild anima
l and the backg round area.
Pedestrians/w ild an imals may not be detected
if the d ifference is too sma ll. Pedestrian and
wild animal marking are deactivated at tem­
peratures above approximately 77 °F
(25 °()
and when it is light outside. When the night
v ision assistant image is selected in the in­
strument cluster d isplay, the

Night vision ass ista nt has limits and ca n­
not always detect pedestr ians . Always pay
close attention to t raffic and the area
a round your veh icle even when nig ht vision
assistant is switched on.
- Night vision assistant can only warn
about people and wild animals located
w ith in the visual range of the infrared
camera. The visua l range corresponds to
the image in the instrument cluster dis·
p lay.
- Night vision assistant may not detect
people or w ild an imals and mark them if
- they a re not in an up right po siti on, for
example if they are si tting or lying
down and/or
- the silhouette in the disp lay is incom­
plete or interrupted, for examp le be­
cause a perso n is partially covered by a
parked vehicle or a wild anima l is parti·
a lly covered by tall grass. This increases
the risk of a collision.
- Never try to swerve to avoid anima ls if
this will put you or other drivers at risk.
This could increase t he risk of a collision.
(D Tips
- Even though the shape and warmth radi·
ated by each object detected is evaluat·
ed, the system does have limitations and
it can give incorrect warnings .
- For technical reasons, the image pauses
in split second intervals.

24 0 Ch eck ing and filling
Always check wi th your a uthorized Audi
dealer to make s ure you are using the
correct brake flu id. The correct type of
brake fluid is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
long. This can ser ious ly affect the effi­
ciency of the b ra kes as well as yo ur
safety. This could result in an acc ident.
(D Note
Brake flu id will damage the paint of your
veh icle.
@ For the sake of the environment
Because of the problem of proper d isposa l
of brake flu id as wel l as the special tools
requ ired and the necessary expert ise, we
recommend that you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
Under
normal operating conditions, the bat­
tery in your Audi does not need any mainte­
n ance . With
high outside temperatures or
l ong daily dr ives we recommend that you have
the elec trolyte level checked by a service fa­
cili ty. The e lec trolyte level sho uld a lso be
checked each time the battery is charged
¢ page 242.
Have the b attery checked when you ta ke yo ur
ve hicl e in for service. Yo u are well adv ise d to
replace a battery that is older than S years .
W ith certa in types of airbag deployment, the
battery is d isconnected from the vehicle ele c­
tr ica l system for sa fety reasons¢
& in Re­
pair, care and disposal of the airbags on
page 165.
Disconnecting the battery terminals
Some veh icle func tions (power w indow regu­
l ato rs, for example) a re los t if the b attery ter- mina
ls are disconnected. These functions have
to be relearned after the battery termina ls are
connected aga in. To prevent th is, the battery
sho uld only be disconnected from the ve hicle
electrical system when abso lutely necessary
for repairs.
Vehicle s not driven for long peri ods
If you do not d rive your vehicle over a period
of several days or weeks, e lectr ica l compo ­
nents are gradually cut back or sw itched off.
This reduces energy consumption and ma in­
ta ins start ing capability over a longer period
¢
page 202. Some of the convenience func­
t ions may not ope rate, such as the inter ior
li gh ts or the power seat adjus tment. The con­
venience func tions will be ava ilable ag ain
when you switch on the ignition and start the
engine .
Winter operation D uring the winte r months, battery capac ity
tends to de crease as temperatures drop. This
is beca use more power is also consumed wh ile
sta rting, and the headlights, rear window de ­
fogger, etc ., are used more often .
Avoid unnecessary power consumpt ion, p ar­
t icu lar ly in city traffic or whe n traveling only
short distances. Let yo ur au thorized Aud i
dealer check the capacity of the vehicle bat ­
tery before winter sets in ¢
page 242. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer.
(!) Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be repla ced.
