then maintains the stored distance. If the ve­
hicle ahead accelerates, adaptive cr uise con­
trol will also accelerate up to the stored
speed.
The higher the speed, the greater the distance
in yards (meters) ¢.&. . The
Distance 3 setting
is recommended .
The distances prov ided are spec ified values.
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
d istance may be more or less than these tar­
get distances.
The various symbols for the time increments
appear briefly in the information line @

A WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to br ing your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe follow- ing distance
for the traffic, road and
weather conditions.
@ Tips
- Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
tro l key being used.

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are nec­
essary, how they work and how to adjust and
wear them correctly.
~ Read all the information that follows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death .
- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents . For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving.
- Pregnant women, injured, or physically
impaired persons must also use safety
belts. Like all vehicle occupants, they are
more likely to be seriously injured if they
do not wear safety be lts . The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions:
two in the front and three in the rear. In some
vehicles, there are four seat ing positions : two
in the front and two in the rear. Each seating
position has a safety belt .
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death .
- Never strap more than one person, in­
cluding small chi ldren, into any belt. It is
especially dangerous to place a safety
belt over a child sitting on your lap.
Safety belts 145
-Never let more people ride in the vehicle
than there are safety belts available.
- Be sure everyone riding in the vehicle is
properly restrained with a separate safe­
ty belt or child restraint.
~-Safety belt warning light
Your vehicle has a warning system for the
driver and front seat passenger to remind you
about the importance of buckling-up.
Fig. 155 Safety bel t warning light in the instrument
cl uster -enla rged
Before driving off, always:
~ Fasten your safety belt and make sure you
are wearing it properly .
~ Make sure that your passengers also buck le
up and properly wear their safety belts.
~ Protect children with a child restraint sys-
tem appropriate for the size and age.
The warning light . in the instrument cluster
lights up when the ignition is on as a reminder
to fasten the safety belts. In addition, you will
hear a warning tone for a certain period of
time .
Fasten your safety belt and make sure that
your passengers also properly put on their
safety belts.
A WARNING
- Safety belts are the single most effect ive
means available to reduce the risk of se­
rious inju ry and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving. •

156 Airbag sys te m
as def ined in the electronic control unit
Q page 164, PASSENGER AIR BAG OFF light.
A lways remember, a chi ld seat or infant carr i­
e r i nsta lled on the front seat may be struck
and knocked out of position by the rapidly in ­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the chi ld restraint and even se­
riously injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for chi ldren -when properly
restra ined accord ing to their age and si ze -we
strongly recommend that children always sit
in the back seat
Q page 177, Child Safety .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child seat
or infant carrier w ith great force and w ill
smash the ch ild seat and child against
the backrest, center armrest, door or
roof .
- Always install rear -facing child seats on
the rear seat .
- If you must install a rearward facing
child seat on the f ront passenge r seat
because of except iona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately i nstall the rear-facing chi ld seat in a
rear seating position and have the airbag
system inspected by your Aud i dealer .
- Forward-fac ing ch ild seats installed on
the front passenger's seat may interfere
with the deployment of the airbag and c ause se rious pe rsonal injury to the
c hild.
A WARNING
If, in exceptional c ircumstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat: -
Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag .
- Never put the forward-facing child re­
straint up against or very near the instru­ ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore a nd
aft adjustment range, as fa r away from
the airbag as possible before installing
the forwa rd-fa cing ch ild restra int. The
b ackrest mus t be ad justed to an up right
position.
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays o n all the
time wheneve r the ignition is switched
on.
A WARNING -ra----
To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light will be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itched on.
- If the
PASSENGER AIR BAG OFF light
does not stay on, perform the checks de­
scribed
Q page 164, Monitoring the Ad­
vanced Airbag System .
-Take t he chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN ­
GER AIR BAG OFF
light does not stay on.
- Have the airbag system inspected by
your Aud i dea le r i mmediately .
- Always carefully follow instr uctions from
child restraint manufacture rs when in­
stall ing c hild restra ints .
A WARNING
If, in except iona l circumstances, you m ust
i nstall a forward o r rearwa rd-fa cing child
r estra int on the front p assenger's se at:
- I mp roper installation of ch ild restra ints
c a n reduce their effectiveness or even
p revent them from providing any protec -
tion. .,..

160 Airbag sys te m
- Always make su re the forward-facing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front a nd side airbag .
- Never put the forward- facing child re­
straint up aga inst or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lli ng
the fo rward-facing chi ld restraint. The
b ackres t must be adjusted to an upr igh t
posit ion.
- Make su re that the
PASSENGER AIR BAG

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 include the
weight-sens ing mat, sensors, wiring, brack­
ets, and more . The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on.
The control unit mo nitors the Advanced Air­
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide information to the Advanced Air­ bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator and
cont ro l valve for the driver ins ide the steer ­
ing wheel hub .
- An Advanced A irbag w ith gas generator and
cont ro l valve inside the inst rument panel for
the front passenger .
- A we ight-sensing mat under the up ho lstery
padding of the front passenge r seat cushion
that measures the total weight o n the seat.
The info rma tion reg iste red is sent continu­
ously to the elec troni c control un it to regu­
la te deployment o f the front Advanced Air ­
bag on the passenger side .
- An airbag monitor ing sys tem and indicator
light in t he instr ument cluster ¢
page 164.
-A sensor in each front se at regis ters the dis ­
t ance between the respec tive seat and the
steering whee l o r instrument panel. The in­
formation registered is sent continuo usly to
the electron ic contro l unit to regulate de­
ployment of the front Adv a need A irbags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instr u­
ment panel ¢
page 164, fig. 168 and tells
you whe n the front Advanced Airbag on the
passe nger side has been turned off .
- A sensor below the safety be lt latch for the
front seat passe nger to measure the tension
on t he safety be lt . The tension on the safety
be lt and the weight registered by t he
weight-sens ing mat he lp the control uni t
