The rain sensor* is only activated w ith the wiper lever set to position
G). When it starts to rain, the rain sensor will automa tically activate
the intermittent wiping mode .
To reduce the sensitivity of the sensor, move switch @down . To
inc rease the sensitivity, move the switch up. The higher you adjust
the sensitivity, the faster the sensor will 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.
The rain sensor wiper interva ls depend on the sensitivity setting as
we ll as vehic le speed. During brief stops, wiper motion will adjust to
the amount of rain on the w indshield.
When the ignit ion is turned on, the washer jets are heated .
With the low beam headlights switched on, pull the wiper lever
towards you only
briefly to c lean 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.

acoustic park assist
A pplies to vehicles : with 4 -c h an nel a cou sti c par k ass is t
Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car.
How it wor ks
The acoustic park assist warning system (4 -channel acoustic park
assist) uses ultrasonic sensors to warn you when you are
backing
your vehicle close to an obstac le . The system 's 4 sensors are located
inside the rear bumper.
A cti va ting
The rea r acoustic park ass ist is activa ted whenever you shift into
Re verse . You will hear a warn ing tone when the system is on.
Reverse
With the car backing up in reverse gear, the collision warning sound
se ts in at the fo llowing
approximate d istances to obstacles:
st raight a ft 5ft(
1.5ml
a ngl ing aft of f ve hicle corners 2 ft (0.6 ml
As the distance shr inks, the time interval between the audible tones
grows shorter.
The sound changes to a continuous tone as soon as the remaining
d istance to an obstacle c loses to less than about 1 ft. (0.3 ml. The
steady tone cautions you that you have backed up hazardously
close and you risk co llis ion by back ing up any furt her .
Malfunction s in the system
If a warning tone is audible for about five seconds when you turn on
the ignition, there is a ma lfunction in the system . Have the prob lem
corrected by your authorized Aud i dealer.
Controls and equip ­
ment
Keep the sensors in the rear bumper clean and free from ic e so t hat
the acoustic park assist system can funct ion proper ly .
& WARNING
• Sensors have dead spaces in which object s cannot be
detected . Be especiall y alert for small ch ildren and animals , since
they are not always dete cted by the sensor s.
• The acousti c pa rk assist system is not a substitute for the
driver's own caution and alertne ss . Ultimate re sponsibility alway s
remains w ith the driver dur ing parking and s imilar maneuvers .
Alway s watch where you are driving _
0 Note
• Remem ber t hat low obstac les for wh ich a warning has already
been issued may "dive" below the system's sensing zone if the
veh ic le is be ing bac ked up cl oser. In this case, the warning sound
shutting off does
not indica te that you have cleared the obstacle .
Instead , impact is imminent.
• Objects such as trai ler hitches, barrier chains, narrow posts or
f ences covered by a th in laye r of pa int may not always be detected
by the system . T hey can sti ll damage your vehic le without a
warning.
[ i ] Tips
Keep the sensors in the rear bumper clean and free of snow and ice
so that the acoust ic park ing ass ist system can function properly .•

Airbag system
Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For airbags to
do their job, occupants must always properly wear their
safety belts and be in a proper seating position.
For your safety and the safety of your passengers, before
driving off, always:
- Adjust the driver's seat and steering wheel properly
=> page 168,
-Adjust the front passenger's seat properly=> page 96,
-Wear safety belts properly=> page 180 ,
- Always properly use the proper child restraint to protect
children
=> page 210 .
In a col lision airbags must inflate within the blink of an eye and with
considerable force . The suppl emental airbags can caus e injuries if
t he driver or the front seat passenger is not seated properly. There ­
fore in order to help the airbag to do its job , it is important, both as
a driver and as a passenger to sit properly at a ll times.
By keeping room between your body and the steering wheel and the
front of the passenger compartment, the airbag can inflate fully and
completely and provide supplementa l protect ion in certain frontal
collisions => page 168, "Proper occupant seating positions" . For
detai ls on the operation of the seat adjustment
contro ls => page 97.
It's especially important that children are properly restrained
=> page 210.
Controls and equip­ ment Safety first Vehicle operation
There is a lot that the driver and the passengers can and must do to
help the individual safety features installed in your Audi work
together as a system .
Proper sea ting position is important so that the fron t airbag on the
driver side can do its job. If you have a physical impairment or
condition that prevents you from sitting properly on the driver seat
with the safety belt properly fastened and reaching the pedals, or if
you have concerns with regard to the function or operation of the
Advanced Airbag System, please contact your authorized Audi
dea ler or qualified workshop, or ca ll Audi Customer CARE at 1 -800-
822 -2834 for possible modifications to your vehicle.
When the airbag system deploys, a gas generator wi ll fill the
airbags , break open the padded covers, and inflate between the
steering whee l and the driver and between the instrument pane l
and the front passenger. The airbags will deflate immediately after
deployment so that the front occupants can see through the wind ­
shie ld again without interruption .
All of this takes place in the blink of an eye, so fast that many people don't even realize that the airbags have deployed. The airbags also
inflate with a great deal of force and nothing should be in their way
when they deploy. Front airbags in combination with proper ly worn
safety belts slow down and limit the occupant's forward movement .
Together they help to prevent the driver and front seat passenger
from hitting parts of the inside the vehicle while reducing the forces acting on the occupant during the crash. In this way they help to
reduce the risk of injury to the head and upper body in the crash.
Airbags do not protect the arms or the lower parts of the body .
Both front airbags wi ll not inflate in all frontal collisions. The trig­
gering of the airbag system depends on the vehic le dece leration
rate caused by the collision and registered by the electronic contro l
unit . If this rate is below the reference value programmed into the
control unit, the airbags will not be triggered, even though the car
may be badly damaged as a result of the collision . Vehicle damage, _,,

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very impo rtant
parts of the Advanced A irbag System in it . These parts include the
we ight -sensing mat , sensors, wiring, brackets , and more. The func -tion of the system in the front passenger seat is checked by the e
lec ­
tronic contro l unit w hen t he ignit ion is on . The co ntrol uni t monitors
the Advanced Airbag System and turns the airbag indicator light on
whe n a malfunction i n the system components is detected. T he
function of the airbag ind icator light is described in greater detai l
below. Because the front passenger seat contains important parts
o f the Advanced Airbag System, you must take care to prevent it
from being damaged . Damage to the seat may prevent the
Advanced Airbag for the front passenger seat from do ing its job in
a crash .
The front Adva nc ed Airbag S ystem consi sts of th e
following :
• Crash sensors in the front of the ve hicle that measure veh ic le
acce leration/deceleration to provide information to the Advanced
A irbag System about t he severity of t he crash .
• An electronic control unit, with integrated crash sensors for front
and side impacts. The control unit "dec ides" whethe r to fire the
front airbags based on the information received from the crash sensors . The control unit also "dec ides" whether the safety be lt
pretensioners should be activated.
• A dual -stage Advanced Airbag with gas generator for the driver
inside the steering wheel hub.
• A dual-stage Advanced A irbag and gas generator inside the
instrument pane l for the front passenger .
• A we ight -sensing mat under the upholstery padding of the front
passenger seat cushion that measures the tota l weight on the seat .
T he information registered is sent continuously to the electronic
control un it to regu late dep loyment of the front Advanced Airbag on
the passenger side .
