• With the light switch at the O or :oo:: position , only your front fog
lights remain turned on when it turns dark outside . Even though
your instrument s appear well lit, the road ahead of you is not. The
light pattern provided by fog lights alone is not sufficient fo r safe
driving in poor light or darkness. Therefore:
• Always be aware of changes in outside light conditions while
you are driving. Respond in time to fading daylight by turning the
light switch to pos ition
io (or "AUTO" if your ca r is equipped with
t h is feature)
to turn on your headlights .•

- Pull the lever to pos iti on © (toward the steering w heel)
and ho ld.
Re lease t he lev er. The washer stops and t he wipers keep
going for about fou r seconds.
Turning off the wipers
- Move the lever back to position @ .
The windshie ld wipers and washer on ly work when the ignition is
turned on .
The rain sensor* is only activated with the wiper lever set to position
G). When it starts to rain, the rain sensor will automatically activate
the intermittent wiping mode .
To reduce the sensitivity of the sensor ,
move switch @down . To
increase the sensitivity, move the switch up. The highe r you adjust
the sensitivity, the faster the sensor wi ll react when it senses mois ­
ture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting, but on the vehicle speed as well.
During brief stops, e.g. at a red light, wiper motion will automati ­
cal ly be reduced to the next lower speed. Wipers already turning at
low speed. change to intermittent wiping.
When the ignition is turned on, the washer jets a re heated .
With the low beam headlights switched on, pull the wiper
lever
towards you only briefly to clean the windshield. Ho lding the wiper
lever would also engage the headlight washer system each time you
clean the windshield and would drain the washer fluid reservoir
prematurely. ..

Seats and storage
Seats and storage
General recommendations
Why is your seat adjustment so important?
The safety belts and the airbag system can only provide
ma ximum protection if the front
seats are correctly
a djusted.
There are var ious ways of adjusting the front seats to provide safe
and c omfortable support for the driver and the front passenger.
Adjust your seat properly so that:
• you can easily and quickly reach all the switches and controls in
the instrumen t pa nel
• your body is proper ly supported to reduce physical stress and
f atigue
• the safety belts and airbag system can offe r maximum protec ­
tion=>
page 768.
I n the fo llowing chapters, you wil l see exact ly how you can best
adjust your seats.
There are special regulations and instructions for instal ling a child
safety seat on the front passenger seat. A lways heed the informa ­
tion regarding child safety provided in=>
page 790, "Child Safety".
& WARNING
Inco rrect se ating po sition of the driver a nd all other pa ssengers
c an result in serious per sonal injury.
• Alway s keep your feet on the floo r when the vehi cle is in motion
- never put your feet on top of the in strument panel , out of the
window o r on top of the seat cushio n! This appl ies espe ciall y to
the pa ssenger s. If your seating position i s incorre ct you increase
the ri sk of inju ry in the c ase of sudden br aking or an accident .
If
& WARNIN G (continued )
the airb ag inflate s and the seating position is incorre ct thi s could
r e sult in per sonal injury or even death.
• It is important for both the driver and front p assenger to keep
a distan ce of at least 10 inche s (25 cm) betw een them se lve s and
the steering wheel and /or in strument p anel . If you are sitting any
closer than this , the airbag system cannot protect you properly . In
a ddition to this , the front se ats and head re str aints mu st be
adjusted to your body height so th at they can give you maximum
protection .
• Alway s try to keep as much distan ce as possible between your­
s elf and the steerin g wheel or in strument p anel.
• Do not adjust the driver's or front pas senger seat while the
vehicle is mov ing . You r seat may mo ve unexpect edly , ca usin g
s udden los s of vehicle control and per sonal injury.
If you adjust
your seat while the vehi cle i s moving , you a re out of position .
0 Note
When the front seats are in the reclined position, make certain that
the seatbacks are not pushed against the built -in air deflector *
when you run the sea ts back toward the rear of the vehicle and
when you lower the seatback. This can damage the air deflector and
the latching mecha nis m. •
Driver seat
The correct seat position is importan t for safe and relaxed
drivin g.
We recomme nd tha t yo u adjust the dr iv e r's sea t in the
fol lowing ma nne r:

- Adjust the seat in fore and aft direction so that you can
easily push the pedals to the floor while keeping your
knee slightly bent==>
& in "Why is your seat adjustment
so important?".
- Adjust the seatback so that when you sit with your back against the seatback, you can still grasp the top of the
steering wheel.
- Position the head restraints according to the occupant's
height. For maximum protection, the upper edge of the
head restraints should be at least at eye level, or higher
==>
page 757,fig.156.
& WARNING
Never place any objects in the driver's footwell. An object could
get into the pedal area and interfere with pedal function. In case
of sudden braking or an accident, you would not be able to brake
or accelerate! •
Front passenger seat
Always move the front passenger seat into the rearmost
position.
To avoid contact with the airbag while it is deploying, do not
sit any closer to the instrument 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:
- Move the front passenger seat into the rearmost position
of the fore and aft adjustment range ==>
& in "W hy is
your seat adjustment so important?" on
page 92.
Controls and eq uip­
ment
Seats and storage
- Bring the backrest up to an (almost) upright position . Do
not ride with the seat reclined.
- The ideal position for the head restra int is with the upper
edge of the restraint level with the top of your head

Steering
Adjusting the steering wheel column
The height and reach of the steering wheel can be
adjusted.
First, adjust the driver's seat correctly.
Fig . 135 Lever under
the steering column
-Push the lever~ fig. 135 -Arrow- ~& .
- Move the steering wheel to the desired position.
- Push the lever against the steering column unt il it locks.
Th ere mus t be at least 10 inches (25 cm) betw een your br eastbone
and the center of the steering wheel. If you cannot sit more than 10
inches (25 cm) from the steering wheel, we recommend that you
investigate whether adaptive equipment is available to help you
reach the pedals and increase your seating distance from the
steering wheel.
For detailed information on how to adjust the driver's seat, see
=> page 96, "Power seat adjustment" .
& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal injury .
• Adjust the steering wheel column only when the vehicle is not
moving to prevent loss of vehicle control.
• Always make sure that the adjustment lever is securely pushed
up so that the position of the steering wheel cannot be changed
unintentionally when the vehicle is moving.
• Adjust the driver's seat or steering wheel so that there is a
minimum of 10 inches
125 cm) between your breastbone and the
steering wheel=> page 148, fig.
154. If you cannot maintain this
minimum distance the airbag system cannot protect you properly.
• If physical limitations prevent you from sitting 10 inches
125
cm) or more from the steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is available.
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in an
accident. Always make sure that the steering wheel is pointed
towards your chest.
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag
inflates.
• Never hold the steering wheel at the
12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub. Holding the steering wheel the wrong way
can cause serious injuries to the hands, arms and head if the
driver's airbag inflates. •
