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 .
If the system is in active standby mode and
the turn signa l is activated before driving over
the lane marker line, the warning does not oc­
cur since the system allows for intentional lane changes .
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 .
If the vehicle is also equipped with Audi adap­
tive cruise control*, the corrective steering
will be more specif ic in regard to the driving
situation . In addition to the lane marker lines,
the system can a lso take into acco unt other
objects such as guard rails. If they are detect­
ed i n close proximity to the veh icle, Audi a c­
tive lane ass ist helps prevent the vehi cle from
driving too close to them . The re is also pass­
ing assistance. The system does not provide
any corrective steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the driver that the ve­
hicle is leaving the lane us ing corrective
Audi acti ve lane a ssis t 95
steer ing. The driver is always responsible
for keeping the vehicle within the lane.
- The system can assist the driver in keep­
ing the vehicle in the lane, but it does
not steer by itself. A lways keep your
hands on the steering wheel.
- Corrective steering may not occur in cer­ tain sit uat ions, such as dur ing heavy
brak ing.
- The camera does not recognize all lane
marker lines. Corrective steer ing can only
take p lace on the side of the vehicle
where lane marker lines are detected .
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane ma rker lines. As a result, cor rect ive
steer ing may be unexpected or may not
oc cur .
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light s hining
into the camera. This can result in a ctive
lane assist not detecting the lane marke r
lines or detect ing them inco rrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the corrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
must not be used when there are poor
road and/or weather condit ions such as
slippery roads, fog, gravel, heavy rai n,
snow and the potent ial for hydroplaning .
Using act ive lane assist under thes e con­
ditions may increase the risk of a crash.

Introduction
Aud i d rive select mak es it possible to expe ri­
ence diffe ren t types of vehi cle se ttin gs i n o ne
ve hicl e. The dr ive r can se lect th ree
Comfort ,
Auto and Dynamic modes in the M MI to
switch between a sporty and a comforta ble
driving mo de.
You c an a lso a djust the setti ng according to
your p re ferences in the
Individual mode . F o r
examp le, you ca n combine settings such as a
sporty en gine t uning with comfortab le steer­
ing.
A WARNING
Improper use of the A udi drive select can
cause collisions, ot her acc idents and se ri­
ous pe rsonal injury.
Description
The vehicle setup in each mode depends on
the veh icl e's featu res. The engine, t ransm is­
sion, stee ring, reve rsible sa fe ty belt tension­
e rs a nd adap tive air su spension are alw ays in­
volved.
Engine and transmission
Depending on the mode, the e ng ine and the
tra nsmission respond quic ker or i n a more bal­
an ced manne r to acce le rator pedal move­
men ts. In the sporty dyn ami c mode, the
tra nsmission sh ifts at highe r RP Ms.
Air suspension*
The adaptive air suspens ion/adaptive air sus­
pension spor t*
(Air suspen sion in the MM I) is
a n e lec tronic ally con trolled air suspension and
da mpi ng sys tem. They are adjus ted depend­
ing on the se lected driving mode, the drive r's
steeri ng, braking an d acceleration input and
the road s urface, ve hicle speed and load. A
sporty setting is generally used in ve hicles
with adaptive air suspension sport*. T
he veh icle clearance varies depending on the
se lected mo de an d the speed .
T he highway setti ng is a ct ivated automatic ally
whe n you dr ive above 7 5 mph (120 km/ h) fo r
more than
3 0 seconds in the Auto or Dynamic
mode. The gro und clea rance is increased a uto ­
matically if the speed drops below
44 mph
(70 km/h) for more than 120 seconds.
Steering
T he s teer ing adap ts in terms of s teer ing effor t
and steering ratios . Indirect stee ring that
moves easily, like the steer ing in comfo rt
mode, is best suited to long drives on a high­
way. In contrast, dynamic mode provides sporty, direct steer ing .
Sport differential*
As a component of the all whee l drive system
(quattro)
¢ page 201, the Sport differential *
dist ributes the driving power to the rear ax le
depending on the sit uat ion. The distrib ution
of power var ies depend ing on the selected
mode, from balanced (comfort) to agile (dy­
nam ic) . Th e goal is a h igh level of ag ility and
ability to acce lerate on cu rves . Th e ve hicl e is
very res ponsive to stee ring.
Curve light*
The curve light adapts to driving on curves .
T he pivo ting act io n and the lighting are also
adapt ed to the mode .
Adaptive cruise control*
The behav ior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise cont ro l
also responds to th e dr iv ing behavior o f th e

8_ WARNING
-The vehicle can also roll when the engine
is stopped .
- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine running whi le in gear. If you must leave
your vehicle when the engine is running, act ivate the park ing brake and move the
selector lever to P.
- Power is st ill transmitted to the wheels
when the eng ine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the b rake when
the engine is runn ing and the se lector
lever is in D/S or R or "tiptronic" mode is
selected .
- Do no t press the accelera tor pedal when
changing the selector lever position
whi le the vehicle is stationary and the
engine is running.
- Never shift into
R or P whi le driving.
- Be fore driv ing down a steep slope, re -
duce you r speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
peda l too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces braking performance, increases
braking d istance or causes comp lete fail­
ure of the brake system.
- To prevent the veh icle from rolling back
when stopping on inclines, always hold it in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
a slipp ing clutch . The clutch opens auto­
matically when it becomes too hot from
the ove rload. An ind icator lamp
[O] illu­
minates and a dr iver message appears
¢ page 114 when the clutch is overload ­
ed.
- If the eng ine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and is locked in P w
it h the park ing brake set
¢ page 227. Otherw ise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied.
(D Note
- When stopping on an incl ine, do not try
to hold t he vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This ca n cause the transmis­
sion to ove rheat and can damage it . Acti­
vate the pa rking brake or press the bra ke
peda l to preven t the vehicle from roll ing.
- Allowing th e vehicle to ro ll when the en­
gine is stopped and the selecto r lever is
in N will d amage the tr ansmission be­
cause it is not l ubricated unde r those cir ­
cumstances .
(D Tips
Fo r saf ety reaso ns, the pa rking br ake is re­
l eased automatically on ly when the d riv­
er's safety belt is engaged in the buckle.
Hill descent control
Appl ies to vehicles: wit h S t ronic/tiptro nic
The hill descent control system assis ts the
driver when driving down declines.
Hill des cent con trol is activated when these­
lector lever is in D/S and yo u press the brake
peda l. The transmission automatica lly selects
a gear that is suitable for the incline . Hi ll de ­
scent contro l tries to maintain the speed ach ­
ieved at the time of braking, within phys ica l
and technical lim itations. If may st ill be nec­
essary to adjust the speed with the brakes .
Hill descent cont ro l switches off once the de­
cline leve ls out or you press the acce lerator
pedal.
On vehicles with the cruise contro l system*
¢ page 84, hill descent control is also activat-
ed when the speed is set. .,..

194 Audi pre sense
Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the deploy­
ment time is adapted in
Dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered :
- Braking guard
c::> page 92
- Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected.
_& WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob­
jects. This increases the risk of a colli­
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path
c::> page 86.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac ­
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.

ESC includes and/or works together with the
anti-lock brake system (ABS) , brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock ( EDL) and e lectronic interax le
d ifferential lock* . ESC is swi tched on all the
time. In certain situat ions when you need less
traction , you can switch off ASR by pressing
the button
[ru <::;> page 198, fig . 182 . Be sure
to switch ASR on again when you no longer
n eed less t raction.
Anti-lock br aking s ystem (ABS)
ABS prevents the wheels from locking up
when braking . The veh icle can still be steered
even during hard braking . Apply steady pres­
sure to the brake pedal. Do not pump the ped ­
a l. A puls ing in the bra ke peda l indicates that
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease brak ing
d istance.
It increases braking power when the
driver p resses the brake pedal quic kly in emer­
gency situations. You must press and ho ld the
b rake peda l until the situation is over . In
vehicles with adaptive cruise control* , the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
small.
Anti -slip regulation (ASR )
ASR reduces engine power when the d rive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
s tart, accelerate and drive up hills.
El ectronic diffe rential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the other drive
wheel or whee ls if the vehicle is equipped with
all-whee l drive*. This function is available up
to about 75 mph (120 km/h).
I n extreme cases , ED L automatica lly switches
off to help keep the brake on the braked whee l
from overheating.
E DL wi ll switch on again au­
tomatically when conditions have returned to normal.
Int ellig ent technolog y 197
Electronic intera xle differential l ock */
se le ctive wheel torque cont rol *
The electronic interaxle differential lock (front
whee l drive) or the se lective whee l torque
cont rol (all-wheel dr ive) operates when dr iv­
ing through curves . The front wheel on the in­
s ide of the curve or both wheels on the inside
of the curve are braked selectively as needed .
T his min imizes sliding in the front wheels and
allows for more p recise d riving through
curves . T he applicable system may no t acti­
vate when driv ing in wet or snowy conditions.
A WARNING
-- ESC, ABS, ASR, EDL and the electronic in­
teraxle diffe rential lock function* cannot
overcome the laws of physics. This is es­
pecially important on slippery or wet
roads . If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change yo ur speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will increase the r isk o f a loss of vehi ­
cle control, collision and serious personal inju ries.
-Always adapt your speed to road, traffic and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . ESC, ABS, the brake assist sys­
tem, EDL, ASR and the e lectronic inte r­
axle d iffe ren tial lock function* cannot
preven t coll is ions.
- Always accelerate with spec ial care on
even, smooth surfaces su ch as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve-
hicle control. .,.
