The instrument c luster and center console illumination (gauges and

Be aware of the followin g difference be tween
models built to US o r Canadian specifications :
• USA models : illumination of the in strument cluster (gauges and
needles), dash and center console around the gearshift lever is
controlled by a light sensor located in the instrument panel. The
instrument panel illum ination will automatically become dimmer
as the daylight fades away and eventually will go out completely
when outside light is very low . This is to remind you , the d river , to
s witch on the headlight s before it gets too dark.
• Canada models : instrument panel illum ination will stay br ight
regardle ss of the inten sity of ambient light . Always be aware of
c hanges in outside light conditions while you are driving . Respond
in time to fading dayli ght by turning the light switch to position
iD
(or "AUTO" if your car is equipped with this feature) to turn on your
headlights. •
Bi-Xenon headlights*
Afte r starting the engi ne, the b i- xeno n headlights are au tomatical ly
adjusted to the load and angle of the vehic le (for example, during
acce lera tion and braking). This prevents oncoming traffi c from
experiencing unnecessary headlight g lare from your bi -xenon head ­

T he windshield wiper lever :::::> fig. 72 has the following posi­
tions:
One -touch wiping
Move the lever to position G), when you want to wipe the
windshield
briefly.
Intermittent wiping ~ l (activating rain sensor)*
Move the lever up to position 0-
- Move the interval set switch@, to change the inter vals .
Low wiper speed
-Move the lever up to position ©-
High wiper speed
- Move the lever up to position @.
Automatic wiper/washer
- Pull the lever to position© (toward the steering wheel)
and hold.
- Re lease the lever . The washer stops and the wipers keep
going for about four seconds .
Turning off the wipers
-Move the lever back to position @.
The windshield wipers and washer only work when the ignition is
turned on. If you switch off the ignition with th e windshield wiper
lever still in the interval wipe position and then come back a while
later and drive off, the rain sensor will reactivate itse lf after the
vehic le speed has exceeded 4 mph (6 km/h).
The rain sensor* is only activated with the wiper lever set to posi­
tion
G) . When it starts to rain, the rain sensor will automatically acti ­
vate the intermittent wiping mode.
To reduce the sensitivity of the sensor , move switch
@ down . To
increase the sensitivity , move the switch up. The higher you adjust
the sensi tivity, 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.
During brief stops , e.g. at a r ed light, wiper mot ion wil l automati ­
cally be reduced to the next lower speed. Wipers a lready turning at
low speed . change to intermittent wip ing.
When the igni tion is turned on, the washer jets are heated.
& WARNING
• Wiper blades are crucial for safe driving! Only when they are in
good condition are they able to clear the windows properly to
provide uncompromising visibility. Worn or damaged wiper blades
are a safety hazard~

Description
The rear acoustic park assist (4 -channel acoustic park assist) deter ­
mines the d istance of the vehic le from an obstac le using u ltrasonic
sensors. The sensors are in the rear bumper. The volume and the
pitch of the chimes can be adjusted through the menu display
=> page 27.
The range at which the sensors start to m easure is about :
To the side
Center rear
Acti v atio n
2 feet (0 .60 m)
5 feet (1.60 ml
The pa rking assist is activated when rever se ge ar is engaged . A brief
tone confirms that the system is activated .
Backing up
Distance warning when backing up starts when an obstacle is
detec ted in the range of the park ass ist system . As the distance
decreases, the time interval between the aud ible tones becomes
shorter .
When the distance is less than 1 foot (0.30 m) , the tone becomes
continuous . At this point you should stop backing up.
Please note that low objects a lready signalled by a warning can
disappear from the sys tem's detection range and wil l not continue

Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
ries.
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
risk 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 strikes an occupant who is not in the correct seating
position. A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling~&.
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants are correctly
restrained and stay in a correct seating position whenever the
vehicle is being used.
• Always read and heed all WARNINGS and other important infor­
mation =>
page 140. •
Safety belt tensioners
How safety belt pretensioners work
In front and side collisions above a particular severity,
safety belts in use are tensioned automatically.
The safety belts are equipped with safety belt pretensioners . The
system is activated by sensors in front and side collisions of great
severity . This tightens the belt and takes up belt slack=>&. in
"Service and disposal of safety belt pretensioner". Taking up the
slack helps to reduce forward occupant movement during a colli­
sion.
[ i] Tips
The safety belt pretensioner can only be activated once.
• In minor frontal and side collisions, in rear-end collisions, in a
rollover and in accidents involving very little impact force, the safety
belt pretensioner are not activated.
• When the safety belt pretensioner is activated, a fine dust is
released. This is normal and is not caused by a fire in the vehicle.
• The relevant safety requirements must be observed when the
vehicle or components of the system are scrapped . A qualified deal­
ership is familiar with these regulations and will be pleased to pass
on the information to you.
• Be sure to observe all safety, environmental and other regula ­
tions if the vehicle or individual parts of the system, particularly the
safety belt or airbag, are to be disposed. We recommend you have
your authorized Audi dealer perform this service for you. •

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced Airbag System in it. These parts inc lude the
weight -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 when the igni tion is on. The control unit monitors
the Advanced Airbag System and turns the airbag indicator light on
when a malfunction in the system components is detected . The
function of the airbag indicator light is described in greater detail
below. Because the front passenger seat contains important parts
of 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 doing its job in a crash.
T he front A dvance d Airb ag Syst em con sis ts of th e
following:
• Crash sensors in the front of the vehicle that measure vehicle
acceleration/dece leration to prov ide information to the Advanced
Airbag System about the severity of the crash .
• An electronic control unit, with integrated crash sensors for front
and side impacts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash sensors. The contro l unit a lso "decides" whether the safety belt
pretensioners should be activated .
• A dual -stage Advanced Airbag with gas generator for the driver
