A WARNING
-Automatic headlights* are only intended
to assist the dr iver. They do not relieve
the driver of responsib ility to check the
headlights and to turn them on ma nually
according to the current light and visibili­
ty conditions . For examp le, 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 .
-Crashes can happen when you cannot see
the road a head and when you cannot be
seen by other motorists . Always turn on
the headlights so that you can see ahead
and so that others can see your car from beh ind.

{!) Tips
- The light sensor for the automatic head­
lights* is in the rearview mirror mount.
Therefore , do not place any stickers in
this area o n the windshield .
- Some funct ions of the exterior lighting
can be adjusted

- If you turn off the ignition while the ex­
terior lights are on and open the door,

- In some countries, the tail lights do not
switch on when the daytime runn ing
lamps switch on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera ­
t u re difference between the inside a nd
outside. They w ill clear shortly after
switching them on . This does no t affect
the serv ice life of the lighting.

(D Tips
You can find out if your vehicle is equipped
with Hill Hold by checking at an authorized
Audi dealer or qualified repair facility .
Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exceeding the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap­ proximately 3 mph (3 km/h). An indicator
light . (USA models) . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns
off when the speed decreases below the
stored maximum speed .
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you may want to do so include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
"' Select: Systems or Car systems > Driver as­
sist> Speed warning .
Driving 79
You can set any threshold between 20 mph (30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Applies to vehicles: with cruise control system
The cruise control system makes it possible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
.&_ WARNING ~
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- 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 a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models) !l'I (Canadian models)
ison.

94 Audi acti ve lan e assi st
Audi active lane assist
Lane assist
Description
App lies to vehicles: with Audi active lane assist
Active lane ass ist 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 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 this warning vibration 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 w arns the d river that the ve­
hicle is leaving the lane us ing 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
marke r lines a re detected .
l) Thi s 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
examp le 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 .
