stra int so that it is as close to the back of
the head as possible .
A WARNING
Never place any objects in the driver's foot­
well. An object could get into the pedal
area and interfere with pedal function. I n
case of sudden braking or an accident, you
would not be ab le to brake or acce lerate.
Front passenger's seat
Always move the front passenger seat into
the rearmost position.
To avoid contact with the airbag while it is de­
ploying, do not sit any closer to the instru­
ment panel than necessary and always wear
the three -point safety belt provided adjusted
correctly . We recommend that you adjust the
passenger's seat in the following manner :
• Bring the backrest up to an (almost) upright
pos ition.
D o not ride w ith the seat reclined.
• For adjustable head restraints : adjust the
head restraint so the upper edge is as even
as possib le with the top of your head. If that
is not possible, try to adjust the head re­
straint so that it is as close to this position
as possible

.. Bring the steering wheel into the desired
position .
.. Push the lever against the steering column
until it latches .
_& WARNING
Incorrect use of the steer ing whee l adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when
the vehicle is stationary so that you do
not Lose control of the vehicle .
- Adjust the driver's seat or steering wheel
so that there is at least 10 inches
(25 cm) distance between your chest and
the steering wheel~
page 126,
fig. 114.
If you do not maintain this dis­
tance, the airbag system will not be able
to provide its full protect ion
<=> page 126, fig. 114.
- If your phys ical characteristics prevent
you from sitting at least 10 inches
(25 cm) or more away from the steer ing
wheel, see if your authorized Audi dealer or authorized Audi Service Fac ility can
provide adapters that will help.
- If your face is level with the steering
wheel, the airbag does not provide as much protection during a co
llision. Al­
ways make sure that the steering wheel is level with your chest .
- Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock pos i­
tions to reduce the risk of injury if the
airbag deploys.
- Never hold the steering wheel in the 12
o'clock position or with both hands on
the rim or the center of the steering
wheel. Holding the steering wheel incor­
rectly significantly increases the r is k of
inj ury to the hands, arms and head if the
airbag deploys.

76 Driving
(D Tips
-If it is difficult to turn the key to position
(D , turn the steering wheel back and
forth slightly to release the steering
wheel lock .
- After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first build up
in the hydraulic valve adjusters. This is
normal and not a cause for concern .
- If the battery is disconnected and recon­
nected, you have to hold the ignition key
in position
(D for five seconds for the en­
gine to start .
- After switching the ignition off, you can
only remove the key when the selector
lever is in the "P" (Park) position. After
that the selector lever is locked.

The locked steering helps prevent vehicle
theft .
_& WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake, if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to accidents and serious injuries . -
Never remove the ignition key from the
ignition look while the vehicle is moving .
Otherwise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle .
- Please note that the brake booster and
power steering only work when the en ­
gine is running. When the engine off, you
must use more force to steer or brake
the vehicle . Because the usual steering
and braking capability is not available,
the risk of accidents or injuries increases.
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time. This applies partic­
ularly when children remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- For safety reasons, always park the vehi­
cle with the selector lever in the P posi­
tion . Otherwise, there is the risk that the
vehicle could roll.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes - even with the ignition
switched off. It can also switch on again
after some time if the coolant tempera­
ture rises as a result of heat buildup or if
the engine compartment is heated by
sunlight and the engine is hot .
(D Note
-If the engine has been under heavy load
for an extended period of time, heat
builds up in the engine compartment af­
ter the engine is switched off -there is a
risk of damaging the engine. For this
reason, let the engine run for at idle for
approximately two minutes before shut­
ting it off.

-When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and pre sense
front will have limited function.
- The adaptive cruise control system and
pre sense front do not react to people,
animals, objects crossing the road or on­
coming objects.
- The function of the radar sensors can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you
cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot bring the vehicle to a
sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
(D Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. The adaptive cruise control
and pre sense front may become impaired
as a result. Have an authorized Audi dealer
or authorized Audi Service Facility check
their function.

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 .

Indicator lights
• Ready:
The indicator light turns on when
the system is ready for use. The system can
now be operated .
• Not ready: The indicator light turns on if
the system is switched on but is inoperable.
This may be due to the following reasons:
- There is no lane boundary line.
- The relevant lane marker lines are not de-
tected (for example, markings in a construc­
tion zone or because they are obstructed by
snow, dirt, water or light ing) .
- The vehicle speed is below the activation
speed of approximately 40 mph (65 km/h)
(the speed may vary depending on your
country) .
- The lane is narrower than 8
ft (2 .5 m) or
wider than 18
