& WARNING
• Wiper bl ades are crucial for safe driving! Only when they are in
good condition are they able to cl ear the windows properly to
pro vide uncompromised vi sibility. Worn or damaged wiper bl ade s
are a safety hazard=>
page 69, "Replacing front w iper blades"!
• The light/rain sensor* is only designed to assist and support
the driver. It remains entirely th e driver's responsibility to
monitor outs ide weather condit ions and to manually ac tivate the
wip ers as soon as rain or dr izzle reduces visibility through the
windshield.
• The windshield must not be treated with water-repellent
mater ial s. They can increase glare under poor visibility conditions
such as wetness, darkness, or when the sun is low on the horizon.
In addition , they can cause the windshield wipers to chatter.
0 Note
• In the case of frost, check whether the windshield wiper blades are
fro zen to the windsh ie ld. Switching on t he w indshield wipe rs can
damage the wiper blades!
• Do not use the wipers to clear a frosted w indow . Using the wipe rs
as a convenient ice scraper will destroy the wiper blades.
• Prior to us ing a car was h, the winds hield wiper system must be
sw itched off (lever in posit io n 0). This helps to prevent unintentional
switching on and demage to t he windshield woper sys tem. ..,.

(]] Tips
• The w indshield wipers are switched off when the ign ition is tu rned
off . Activate the windshield wipers after the ignition is switched back
on by mov ing the w indshield wipe r leve r to any pos ition.
• Worn or dirty windshield w iper blades cause smearing, which can
affect the operat io n of the l ight/rain sensor*. Check t he condi tion of
your windshield wiper b lades regularly.
• The rain sensor is part of the inte rval wiping system . Turning off
the ignition will also deactivate the rain sensor. To reactivate the
sensor, switch off the inte rval wiping funct ion, the n switch it back on
again .
• Applies to veh icles with light/ra in sensor: When the w ipers are
switched on manually and in rain conditions, the automatic head­
lights* turn on~
page 56, "Switching the headlights on and off ·f!: "
or off during the day when the wipers are no longer operating. The
au tomatic headlights* func tion is available in t his case only when the
light switch is in the "AUTO" position~

• Make su re the washe r fl ui d reservoir in the eng ine compartment is
topped off before going on a long trip. Look up::::)

• T he shoulder belt part shou ld route approximate ly over the
middle of your shoulder -under no circumstances shou ld it route over
you r neck a nd throat area~ & in "Safety belt position" on
page 140 .
• With the front seats, the height adjustment of the seat can also
be used to adjust the position of the safety belts. •
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
nes.
Wearing safety belts improperly can cause serious injury or
death . Safety belts can only work when they are correctly
positioned on the body . Improper seating positions reduce
the effectiveness of safety belts and will even increase the
ris k of injury and death by moving the safety belt to critical
areas of the body . Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and str ikes an occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all vehicle occu­ pants and especially for chi ldren. T herefore:
- Never permit anyone to assume an incorrect sitting posi-
tion in the vehicle while traveling
~ & .
The fo llowing lists on ly some examples of imprope rly worn safety
belts th at will increase the risk of ser ious injury and death . O ur hope
is that these examples w ill make you more aware of seat ing pos itions

Therefore, whenever the vehicle is moving :
• never wear the sho ulder belt unde r yo ur arm
• neve r let the shoulder be lt pass ove r you r neck
• neve r wear the safety belt loosely

Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear end collisions above a particular
severity, safety belts are tensioned automatically .
The safety belts are eq uipped with safety belt p retensioners. The
system is activated by sensors in fron t, side and rear-end collisions of
great sever ity. Thi s tightens t he be lt and takes up belt slack~ & in
"Service and disposal of sa fety belt p retens ioner". Tak ing up the slack
helps to reduce forward occupan t movement during a collis ion .

Never le t the bel t remain over a rear seatback that has been folded
forward.

& WARNING (conti nued)
immediately install the rear -facing child safety seat in a rea r

authorized Audi dealer.
& WARNING
If , in exceptional circumstances , you must install a forward-facing
child restraint on the front pa ssenger' s seat:
• Always make sure the forward-facing seat has been designed
and certifi ed by its manufacturer for use on a front seat with a
passenger front and side airbag.
• Never put the forward -facing child restraint up against or very
near the in strument panel.
• Always move the passenger seat into its rearmost posit ion in
the seat's fore and aft adjustment range, as far away from the
airbag as possible, before installing the forward-facing child
re straint. The backrest must be adjusted to an upright position.
• Make sure that the
PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on .•
Advanced Airbag System components
Th e fron t passenger sea t in your veh icle ha s a lot of very im port ant
parts of the Advanced A irbag System in it . These parts include the
we ight- sens ing mat, sensors, wiring, bracke ts, and more. The func ­

t ron ic control unit w hen the igni tion is on. The contro l unit mo nitors
the Advanced Airbag System and tu rns the airbag indica to r li ght on

The front Advanced Airbag System consists of the
following:
• Cras h sensors in the front of t he veh icle that measure vehicle
a cc ele ra tion/de ce le ra tion to prov ide i nform ation to the Adv ance d
Airbag System about the severi ty of the crash .
• An e lec tron ic contro l uni t, w ith integr ate d cr ash sensor s fo r fron t

& WARNING
Damage to the front passenger seat can prevent the front airbag
from working properly.
• Imprope r repair or disassembly of the front passenger and
driver seat will prevent the Advan ced Airbag System from func­
tioning properly.
• Repairs to the front passenger seat must be performed by qual­
ified and properly trained workshop personnel.
• Never remove the front passenger or driver seat from the
vehicle.
• Never remove the upholstery from the front passenger seat.
• Never disassemble or remove parts from the seat or disconnect
wires from it .
• Never carry sharp objects in your pockets or place them on the
seat. If the weight-sensing mat in the passenger seat is punctured
it cannot work properly .
• Never carry th ings on your lap or carry objects on the passenger
seat . Such items can increase the weight regi stered by the weight­
sensing mat and send the wrong information to the airbag control
unit.
• Never store items under the front passenger seat. Parts of the
Advanced Airbag System under the passenger seat could be damaged, preventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats .
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraint s or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly .
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(co ntinued )
• Never use cushions , pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
c hild restraint or person on the seat and prevent the Advanced
Airbag System from functioning prope rly.
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel, foam cushion or something else to properly pos ition
the child restraint, make certain that the PASSENGER AIR BAG
OFF light come s on and stays on whenever the child re straint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install child restraint in a rear seating posi­
