Within the limits of the system, adaptive cruise
control can react to stationary vehicles
¢
fig. 110, as long as you are driving slower than
30 mph (SO km/h) and the system class ifies the
possible passing maneuver as low. For example,
if a vehicle that was already detected
@ turns or
changes lanes, the adaptive cruise contro l reacts
to the stat iona ry vehicle ahead of
it @ .

Driving sa fe ty
Loose items in the luggage compartment can
shift s udden ly, changing vehicle handling charac­
ter istics. Loose items can also increase the risk of
serious personal in jury in a sudden vehicle
ma­
neuver or in a coll is ion.
.,. Distribute the load evenly in the luggage com­
partment .
.,. Always place and properly secure heavy items in
the luggage compartment as low and as far for­
ward as possible

A WARNING
Improperly stored luggage or othe r items can
fly through the vehicle causing serious per­
sonal injury in the event of hard braking or an
accident. To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always sec ure objects in the luggage com­
partment using the tie-down eyelets and
s u itable straps.
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To he lp reduce the r isk of a loss
of contro l leading to serious pe rsonal i njury:
- Always keep in mind when transporting heavy objects, that a change i n the center of
grav ity can also cause changes in vehicle
hand ling:
- Always distr ibute the load as even ly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible.
- Never exceed the Gross Axle Weight Rating
o r the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the driv­
er's side B-pillar respective ly on the front
end of the driver's door. Exceeding permissi­
ble weight standards can cause the veh icle
to slide and handle differently .

-Please observe info rmation on safe driving
¢page 254.
A WARNING
To he lp prevent po isonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­
cause the rear lid cannot be fully closed.
- If you absolutely must dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning :
- C lose all windows,
- Close the s unroof*,
- Open all a ir outlets in the instrument pan-
el,
- Switc h off the air reci rculat ion,
- Set the fresh air fan to the highest speed.
A WARNING
-
Always make sure that the doo rs, all win­
dows, the sunroof * an d the rear lid are se­
curely closed and locked to red uce the risk of
i n jury when the veh icle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked.
- Never leave your ve hicle unattended espe­
cially with the rear lid left open. A child

Airbag system
Important information
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 prop­ er seating position.
For your safety and the safety of your passen­
gers, before driving off, always :
.,. Adjust the driver's seat and steering wheel
properly
9 page 255,
.,. Adjust the front passenger's seat properly
¢page 256,
.,. Wear safety belts properly¢ page 265,
.,. Always properly use the proper child restraint
to protect children ¢
page 295.
In a collision, airbags must inflate within the
blink of an eye and with considerable force. The
supplemental airbags can cause injuries if the
driver or the front seat passenger is not seated
properly. Therefore 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 all 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 supplemental protection in certain frontal
collisions ¢ page 255, Correct
passenger seating positions .
For details on the
operation of the seat adjustment controls
¢page 65.
It's especially important that children are proper­
ly restrained
¢page 295.
There is a lot that the driver and the passengers
can and must do to help the individual safety fea­
tures installed in your Audi work together as a
system.
Proper seating position is important so that the
front 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
Airbag system
reaching the pedals, or if you have concerns with
regard to the function or operation of the Ad­
vanced Airbag System, please contact your au­
thori zed Audi dealer or qualified workshop, or
call Audi Customer Relations at 1-800-822-2834
for possible modifications to your vehicle.
When the airbag system deploys, a gas generator
will fill the airbags, break open the padded cov­ ers, and inflate between the steering wheel and
the driver and between the instrument panel and
the front passenger. The airbags will deflate im­
mediately after deployment so that the front oc­
cupants can see through the windshield 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 properly worn safety belts slow
down and limit the occupant's forward move­
ment . Together they help to prevent the driver
and front seat passenger from hitting parts of
the inside of 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 will not inflate in all frontal
collisions . The triggering of the airbag system de­
pends on the vehicle deceleration rate caused by
the collision and registered by the electronic con­
trol 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. Vehi­
cle damage, repair costs or even the lack of vehi­
cle damage is not necessarily an indication of
whether an airbag should inflate or not.
Since the circumstances will vary considerably between one collision and another, it is not possi­
ble to define a range of vehicle speeds that will
cover every possible kind and angle of impact
that will always trigger the airbags . Important
factors include, for example, the nature (hard or
soft) of the object which the car hits, the angle of
impact, vehicle speed , etc. The front airbags will

Airbag System for the front passenger seat from
doing its job in a crash.
The f ront Ad vanced Airb ag S ystem con sists
of t he follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System about the severity of the crash.
-An electronic control un it, 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 control unit also
"de­
c ides" whether the safety belt pretens ioners
shou ld be activated .
-An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer ing
wheel hub.
-An Advanced Airbag with gas generator and contro l valve inside the instrument pane l for
the front passenger.
-A capac itive passenger detect io n system unde r­
neath the front passenger seat cover. This sys­
tem measures the elect rical capac ita nce of the
person in the seat. The i nformation registe red
is sent continuously to the electron ic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side.
-An airbag monitoring system and indicator
light
m in the instrument cluster .
-A sensor in each front seat reg isters the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent continuously to the
electronic control unit to regulate deployment
of the front Advanced A irbags.
-The PA SS EN GER AIR BAG OFF ~; ON@ light
comes on in the
headliner¢ page 283,
fig. 241 and tells you the status of the Ad­
vanced Airbag on the passenge r side .
-A sensor in the safety belt latch for the dr iver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transm its this info rmat ion to the elect ronic
contro l unit.

_& WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from funct ion ing
properly.
- Repairs to the front passenger seat must be
performed by qualified 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 w ires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger detect ion mat in the front passenger
seat will not function p roperly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat. S uch ob­
jects can influence the capacitance reg is­
tered by the capacitive passenger detection
system, so that incorrect informa tion is pro­
vided to the airbag control unit.
- Never store i tems unde r the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from working proper ly.
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld re­
stra ints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restra int system on
this seat.
- Never use cushions, p illows, blankets, or
similar items on the front passenge r seat .

Airbag system
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly . This is why you should
always wear your safety belt, not just because
the law requires you to do so ¢
page 263, Gener­
al information.
Remember too, airbags will deploy only once and
only in certain k inds of accidents - your safety
belts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
examp le when your vehicle str ikes or is struck by
another after the first collision .
This is jus t one of the reasons why an airbag is
not a substitute for the safety belt. The a irbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correct ly.
It is important to remember that while the sup­
p lemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju ­
ries, for example, swe lling, bruising and minor
abrasions and friction burns can also occur when
an airbag inf lates .
The knee airbag system basically consists of:
- T he electronic control module
- T wo inflatab le airbags (airbag and gas genera-
to r), one for the driver and one for the front
pass enger
- The airbag indicator ligh t in the instrument
panel
The knee airbag system will not deploy:
-whe n the ignition is switched off
- in frontal collisions when the deceleration
measured by the control un it is too low
- in side collisions
- in rea r-end collisions
288
-in rollovers
- in the event of a system malfunction (warning/
ind icator light is on)
¢page 32 .
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating
position ¢ page 281 .
-If the airbag indicator light ¢ page 32
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
How knee airbags work
The risk of injury to the leg area con be reduced
by fully inflated knee airbags.
Fig. 243 In flated a irbags protect ing in a fro nta l coll ision
The knee airbag system has been designed so
that the airbags for the dr iver and front passen­
ger dep loy in certain but not all fronta l collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met .
When the system deploys, the airbags fill with a
prope llant gas, and inflate between the lower
part of the instrument panel and the driver and
the lower part of the instrument panel and the
front passenger
¢page 281, fig. 240 .
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex­
tremities.
