& WARNING
-Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights
io
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
theheadlightssothatyoucanseeahead and so that others can see your car from
the back .
- Please observe legal regulations when
using the lighting systems described .
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
{D) Tips
- The light sensor* for automatic head
light range control* is located in the rear
view mirror mount . You should therefore
not apply any stickers to the windshield
in this area in order to prevent malfunc
tions or failures .
- In the event of a light sensor malfunc
tion, the driver is notified in the instru
ment cluster display ~
page 22 .
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched 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 will clear shortly after
switching them on. This does not affect
the service life of the lighting.
Emergency flasher
The emergency flasher makes other motorists
aware that you or your vehicle are in an emer
gency situation .
Fig. 34 Ce nte r co nso le: em erg en cy flash er sw itc h
.. Press the switch I:;,,. ~fig. 34 to turn the
emergency flashers on or off.
When the emergency flasher is on, all four
turn signals blink at the same time. The turn
signal indicator lights
B Nin the instrument
cluster, as well as the light in the emergency
flasher switch
I:;,,. blink likewise. The emergen
cy flashers also work when the ignition is
turned off.
The emergency flashers will turn on automati
cally if you are in an accident where the airbag
has deployed.
@ Tips
You should turn on the emergency flashers
when:
- you are the last vehicle standing in a traf
fic jam so that any other vehicles coming
can see you, or when
- your vehicle has broken down or you are
in an emergency situation, or when
-your vehicle is being towed by a tow
truck or if you are towing another vehicle
behind you.

-Any articles of cloth ing that you have
hung up must not interfere with the driv
er's view. The coat hooks are designed
only for lightweight clothing. Never hang
any clothing w ith hard, pointed or heavy
objects in the pockets on the coat hooks. During sudden braking or in an accident -
especially if the airbag is deployed -
these objects could injure any passen
gers inside the vehicle.
- To reduce the r isk of personal injury in an
acc ident or sudden stop, always keep the
glove compartment closed whi le driving.
- Read and fo llow all WARN INGS
~ page 167, Important safety instruc
tions on the side airbag system.
- Hang clothes in such a way that they do
not impair the driver's v ision .
- T he coat hooks m ust only be used for
lightwe ight clothing. Do not leave any
heavy or sharp edged objects in the pock
ets which may interfere with the side cur
tain a irbag deployment and can cause
persona l injury in a crash.
- Do not use coat hangers for hanging
clothing on the coat hooks as this can in
terfere with proper deployment of the
side curtain airbags in an accident.
- Do not hang heavy objects on the coat
hooks, as they cou ld cause personal in
jury in a sudden stop.
- For strength-related reasons, the mount
ing hooks can only be used to secure ob
jects weighing up to 10 lb. (5 kg). Heavi er objec ts will not be adequately secured
- there is a risk of injury.

A WARNING
- Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and
the distance between your vehicle and
other vehicles .
- For safety reasons, the cruise control
should not be used in the city, in stop
and-go traff ic, on twist ing roads and
when road conditions are poor (such as ice , fog, grave l, heavy ra in and hydro
planing) -risk of accident.
- Turn
off the cruise control temporar ily
when entering turn lanes, highway exit lanes o r in construc tion zones.
- Please note that inadvertently "rest ing"
yo ur foot on the accelerator peda l causes
the cruise control not to brake . T his is
because the cr uise control is overridden
by the d river's acce leration .
- If a brake system malfunc tion such as
overheating occurs when the cruise con
tro l system is switched on, the braking
function in the system may be switched

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 in close proximity to the veh icle, Audi a c
tive lane ass ist helps prevent the vehicle from
driving too close to them . There 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 9 1
steering. 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 situat 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
ra in, 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 rain,
snow and the potent ial for hydroplaning .
Using act ive lane assist under thes e con
ditions may increase the risk of a crash.
