Aud i adapti ve lig ht*
The adaptive light on ly functions when the
light switch is in the AUTO position. You can
deactivate adaptive light in the MMI
c:> page

When switched on, adapt ive light adjusts to
curves depending on the vehicle speed and
steering whee l ang le. This provides better
l ighting through the curve . The system op er­
ates in a speed range from approximately
6 mph (10 km/h) to 68 mph (110 km/h).
St atic corner ing li ght * (vehicles with adaptive
l ight) -th e corne ring light switches on auto ­
matically when the steering whee l is tu rned at
a cert ain angle a t speeds up to approximately
44 mph (70 km/h) and when the turn signal is
activated at speeds up to approximately
25 mph (40 km /h). The area to the s ide of the
ve hicle is il luminated better when turning .

(Vehicles with adaptive light or L ED head ­
lights) -This function adapts the light ing for

A WARNING
-Automatic headligh ts* are only intended
to assist the dr iver. They do not re lieve
the driver of responsibility to check the headlights and to turn them on manua lly
according to the current light and visib ili­
ty conditions. For example, fog cannot be detected by the light sensors. So al­
ways switch on the low beam under
these weather conditions and when driv­ ing in the dark
io .
-Acc idents could occur if you cannot see
the road ahead of you well and if othe rs
on the road cannot see you. Always
swit ch you r headlights on so that you can Ligh
ts and Visi on 4 7
see the road ahead of you and ot hers can
see your vehicle from behind.
- Please observe legal regulations when
using the lighting systems described.
(D Note
The rear fog lights shou ld only be turned
on in accordance with traffic regu lations,
to prevent glare for traffic behind your ve­
hicle.
(D Tips
- The light sensor for the automatic head ­
lights * is in the rearview mirror mount.
Therefore, do not place any stickers in
this area on the windshield .
- Some functions of the exterior lighting
can be adjusted
c:> page 48.
-If you turn off the ignition while the ex­
terior lights are on and open the door,
you will hear a warning tone.
- The tail lights do not switch on when the
daytime running lights switch on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside . They w ill clear shortly after
switching them on . This does not affect
the se rvice life of the lighting.
- A message w ill appear in the instrument
cluster if there is a malfunction in the
light senso r

84 Driving
-For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on winding roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -you could have an accident .
- Switch the cruise control off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking.
This is due to the control system being
overridden by the driver's acceleration.
- If there is a brake system malfunction
such as overheating when the speed
warning system is switched on, the brak­
ing function in the system will be deacti­
vated. The remaining speed warning sys­
tem functions will remain active, as long
as the
B (USA models)/ ii (Canada
models) indicator light is on.
@ Tips
- The cruise control system is ideal for
stretches with speed limits. The driver is
responsible for adhering to the correct
speed.
- The cruise control remains active when
shifting gears.
- The brake lights turn on when the brakes
are activated.

hold the lever in the 010 direction until
the desired speed is reached.
Overriding the speed
You can press the accelerator pedal down to
increase your speed, for example if you want
to pass someone. The speed you saved earlier
will resume as soon as you release the acceler­ ator pedal.
If, however, you exceed your saved speed by 5
mph (10 km/h) for longer than 6 minutes, the
cruise control turns off temporarily. The
II
(USA models) / Bl (Canada models) indicator
light in the instrument cluster turns off and
the stored speed is retained .

You can preselect your desired speed when
the vehicle is stationary .

Audi active lane assist
Lane assist
Description
App lies to vehicles: with Audi active lane assist
Active lane ass ist detects lane ma rker lines
within t he lim its of the system using a camera
in the w indshield . If you a re approaching a de­
tected lane marker line and it appears likely
that you wi ll leave the lane, the system will
warn you with corrective steering. You can
ove rride this steering at any time . If you pass
over a line, the steering wheel will vibrate lightly. In order for th is warning v ibration to
occur, it must first be switched on in the MMI.
Active lane ass ist is operable when the lane
marker line is detected on at least one side of
the vehicle .
The system will not warn you before cross ing
a lane marker Line if you have activated the
turn signal. In t his case, it assumes that you
a re changing lanes intent ionally.
The system is designed for driv ing on express ­
ways and h ighways and therefore only acti­
vates at speeds above app roximately 40 mp h
(65 km/h).
A WARNING
- The sys tem wa rns the d river that the ve­
hicle is leaving the lane using corrective
steering . The driver is always responsible
for keeping the vehicle within the lane .
- The system can help you keep the vehicle
in the lane, but it does not drive by itself.
Always keep your hands on the steering
wheel.
- Co rrective stee ring may not occur in cer­
tain situations, such as d uring heavy
braking.
- There may be cases where the camera
does not recognize all lane marker lines.
Corrective steering can only take p lace
on the side of the veh icle where lane
marker lines are detected .
l) Th is func tion is not available in a ll co untries.
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane marker lines. As a result, correct ive
steer ing may be unexpected or may not
occ ur.
- The camera view can be restricted, for
example by vehicles driving ahead or by
ra in, snow , heavy spray light shining into
the camera or by dirt on the window . T his
can result in act ive lane assist not detect­
ing the lane marke r lines or detec ting
them incorrect ly .
- I n certain sit uat ions where visibili ty is
low, the vehicle may swi tch from "early"
to "late" corrective steering
l).
-Unde r ce rtain condi tions such as ruts in
the road, an incl ined roadway or c ross­
winds, the corrective steering alone may not be enough to keep the vehicle in the
middle of the lane.
- For safety reasons, active lane assist
must not be used when the re a re poor
road and/or weather conditions such as
slippery roads, fog, grave l, heavy rain,
snow and the potential for hydroplaning .
Using act ive lane assist under these con­
d itions may increase the risk of a c rash .
