Cruise control
Introduction
The cruise control system keeps the speed
constant .
The cruise control system makes it possible to
drive at a constant speed over 20 mph (US
model) or 30 km/h (Canadian model). This is
true only to the extent that engine power or
engine braking effect allow . Using the system
takes the strain off the "gas peda l foot" -es­
pec ial ly on long tr ips.
In the control mode, the indicator light in the
instrument cluster is lit
(Dj;(i )~i~ (US model) ,111
(Canadian model).
The cruise control system automatically
switches itself off imm ed iately under the fol­
lowing cond itions:
- Pressing the brake pedal.
- Pressing the clutch pedal.
A WARNING
-Always pay attention to traffic even when
the cruise control system is switched on.
You are always responsible for your
speed and the distance between your ve­ hicle and other vehicles.
- For safety reasons, the cruise control sys­ tem shou ld not be used in the city, in
stop-and-go traffic, on twisting roads
and when road conditions are poo r (such
as ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident.
- Turn off the cr uise control system tem­
porarily when entering turn lanes, high­
way exit lanes or in construction zones.
- Please note that inadvertently "rest ing"
your foot on the accelerator peda l causes
the cruise control system not to brake .
This is because the cruise contro l system
is overridden by the driver's acceleration.
(D Note
On manual transmission vehicles: If you
shift into neutral with the cruise contro l
On th e road 81
system switched on, always depress the
clutch pedal! Otherwise the engine will
race and could be damaged as a result .
(D Tips
When driving on steep downward grades,
the cruise control system cannot keep the
speed constant. The vehicle's own weight
increases the speed. Shift into a lower gear
i n plenty of t ime or brake the vehicle with
the foot brake .
Saving the speed
The desired speed must be saved.

104 Driving Safel y
Pedal area
The pedals must always be free to move and
must never be interfered with by a floor mat
or any other object.
• Make sure that all pedals move freely w ith­
out interference.
• Make sure that noth ing prevents all pedals
from returning to their orig inal positions.
Only use floor mats that leave the pedal area
free and can be secured w ith floor mat fasten­
e rs .
If a brake circuit fails, increased brake pedal
travel is required to bring the vehicle to a full
stop .
A WARNING ,_
Pedals that cannot move freely can cause
loss of vehicle control and increase the r is k
of serious injury.
- Never place any objects in the driver's
footwell. An object could get into the
peda l area and interfere w ith pedal func ­
tion . In case of sudden braking or an ac­
cident, you would not be able to brake or
accelerate!
-Always make sure that nothing can fa ll
or move into the driver's footwell.
Floor mats on the driver side
Always use floor mats that can be securely attached to the floor mat fasteners and do
not interfere with the free movement of the
pedals.
• Make sure that the f loor mats are proper ly
secured and cannot move and interfere with
the pedals
q .&_ .
Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so
that they cannot s lip out of position. You can
obtain suitable floor mats from your author­ ized Audi dealer .
A WARNING
Pedals that cannot move free ly can result
in a loss of vehicle control and increase the
risk of ser ious personal injury.
- Always make sure that floor mats are
properly secured.
- Never p lace or install floor mats or other
floor coverings in the vehicle that cannot be properly secured in place to prevent
them from slipping and interfer ing with
the peda ls or the ab ility to control the
veh icle.
- Never p lace or install floor mats or other
f loor coverings on top of al ready instal­
led floor mats. Add itiona l floor mats and
other coverings will red uce the size of
the peda l area and interfere w ith the
pedals.
- Always properly reinstall and secure floor
mats that have been taken out for clean­
ing.
- Always make sure that objects cannot
fall into the driver footwell while the ve­
h icle is moving. Objects can become
trapped under the brake pedal and accel­
erator pedal causing a loss of vehicle
control.
Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­ erly stowed and secured in the luggage com­
partment.
Loose items in the luggage compa rtment can
shift suddenly, changing vehicle handling
charac teristics. Loose items can also increase
the risk of serious personal injury in a sudden
vehicle maneuver or in a collision.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missi les that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.

For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10- lb (4.5 kg) object are about 20 times the
norma l weight of the item. This means that
the we ight of the item would suddenly be
about 200 lbs . (90 kg) . You can imagine the
in juries that a 200 lbs. (90 kg) item flyi ng
freely throug h the pass enge r compartment
could cause in a collision li ke t his.
_& WARNING
Imprope rly stored luggage or other items
can fly through the vehicle ca using se rious
personal in jury in the event of har d brak ­
ing or an acc ident . To help reduce the r is k
of serious personal injury :
- Always put objects, for examp le, luggage
o r othe r heavy items in the luggage com­
partment.
_& WARNING
Heavy loads will influence the way your ve­
hicle handles. To help reduce the r isk of a
loss of control leading to ser ious personal
injury:
- Always keep in m ind whe n transporting
heavy objects, t hat a change in t he cen ­
ter of g ravity can also cause c hanges in
vehicl e handling.
- Never exceed the G ross Ax le Weight Ra t­
ing or t he Gross Veh icle Weight Rating
spe cified on t he safety compliance stic k­
er on t he left door jamb. Exceeding pe r­
missib le we igh t standa rds can cause the
vehicle to s lide and handle differently.
- Please observe info rm atio n on s afe driv­
ing

_& WARNING , ~ ~
Always make su re that the doors, all win ­
dows and the front lid are securely closed
an d locked to red uce the risk of in jury
when the veh icle is not being used .
- After closing the front lid, a lways make
s u re that it is properly closed and locked .
- Never leave you r vehicle unatten ded es­
pecially with the front lid left open . A

- Never let ch ildren play i n or around the
veh icle .
- Never let passengers ride in t he luggage
compartment . Vehicle occupants must
always be prope rly restra ined in one of
the vehicle 's seating pos it ions .

Reporting Safety
Defects
Applicable to U.S.A.
If you believe that your vehi cle
ha s a defect which could cau se
a crash or could caus e injury or
death, you should immediately inform the National Highway
Traffic Safety Administration (NHTSA) in addition to notify­
ing Audi of Amer ica , Inc .
If NHTSA receives similar com­ plaints, it may open an investi­
gation , and if it finds that a
safet y defect s exists in a group .,.

-Always keep feet in the footwell in front
of the seat while the vehicle is being driv­
en .
- Never let any person ride with feet on
the instrument panel or sticking out the
window or on the seat.
- Never remove a safety belt while the ve­ hicle is moving. Doing so will increase
your risk of being injured or killed .
- Never wear belts twisted.
- Never wear belts over rigid or breakable
objects in or on your clothing, such as
eye glasses, pens, keys, etc., as these
may cause injury.
- Never wear the shoulder part of the belt
under your arm or otherwise out of posi­
t ion .
- Several layers of heavy clothing may in­
terfere with correct positioning of belts
and reduce their effectiveness .
- Always keep belt buckles free of anything
that may prevent the buckle from latch­
ing securely .
- Never use comfort clips or devices that
create slack in the shoulder belt. Howev­
er, special clips may be required for the
correct use of some chi ld restraint sys­
tems.
- Never allow safety belts to become dam­
aged by being caught in door or seat
hardware.
- Torn or frayed safety belts can tear and
damaged belt hardware can break in an
accident. Inspect belts regularly.
If web ­
bing, bindings, buckles, or retractors are
damaged, have belts replaced by an au­
thorized Audi dea ler or qualified work­
shop.
- Safety belts that have been worn and
loaded in an accident must be replaced
with the correct replacement safety belt
by an authorized Audi dealer or qualified
workshop . Replacement may be necessa ­
ry even if damage cannot be clearly seen.
Anchorages that were loaded must also
be inspected .
- Never remove, modify, disassemble, or
try to repair the safety belts yourself.

Illustrating the
principle of an accident
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
p eople riding in vehicles .
Fig. 114 Unbelted occupants in a vehicle heading for a
wa ll
Fig. 11S The ve hicle c rashes in to the wal l.
The physical principles are simple. Both the
vehicle and the passengers possess energy
which vari es with vehicle speed and body
weight. Eng ineers call this energy "k inetic en­
ergy."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor.
If
the speed doubles from 15 to 30 mph (25 to
50 km/h), the energy increases 4 times!
Because the occupants in this vehicle are not
using safety belts
c:>fig . 114, they will keep
moving at the same speed the veh icle was .,,_

Child restraints on the front seat - some
important things to know
.. Be sure to read the important informat ion
and heed the WARNINGS for important de­
tai ls about chi ldren and Advanced Airbags
i=> page 138.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
a ll chi ldren, especially those 12 years and
younger, are properly restrained for their age and s ize. The airbag on the passenger side
makes the front seat a potentially dangerous
p lace for a child to ride . The front seat is not
the safest place for a child in a forward-facing
chi ld safety seat. It can be a very dangerous
p lace for an infant or a c hild in a rearward-fac ­
ing seat.
The Advanced Airbag System i n your veh icle
h as been cert ified to comp ly with the require­
men ts of Uni ted States Federa l Mo to r Veh icle
Safety Standard
208 as applicable at the time
your ve hicle was manufactured.
The Standard requires the fron t air bag on the
passenger side to be turne d off ("sup­
p ressed") if a chi ld up to about one year of
age restrained in one of the rear -facing or for­
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard
208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed o n the front
passenger seat . For a listing of the child re­
straints that we re used to certify compliance
w ith the US Safety Sta ndard

T he PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control u nit.
Each t ime you tur n on the ignition, the
PAS­
SENGER AIR BAG OFF
l ight w ill come on for a
few seconds a nd:
- will stay on if the front passenger seat is not
occup ied ,
- will stay on if there is a small child or ch ild
restraint on the front passenger seat,
A irbag sys tem 119
- will go off if the front passenger seat is oc ­
cupied by an adult as registered by the
weight -sensing mat
c> page 128, Monitor­
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
whe n the contro l unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off.
If the total weight on the front passenge r
seat is more than that of a typical
1 year-o ld
c h il d but less than the weight of a small
adult, the front airbag on the passenger side can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENGER
AIR BAG OFF
light does not come on, the
front a irbag on the passenger side has not
been turned off by the elect roni c con trol unit
and can deploy if the control unit se nses an
impact that meets the cond it ions stored i n its
memory .
For example, th e airb ag may deplo y if:
- a small ch ild that is heav ie r than a typical 1
year-old ch ild is o n the front passenger seat
(regard less of whether the child is in one of
the ch ild safety seats listed
c> page 140), or
- a child who has outgrown chi ld restraints is
on the front passenge r seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument panel will come on and stay
o n.
The front airbag on the passenger side may
not deploy (t he PASSENGER AIR BAG OFF
light does not illum inate and stay lit) ev en if a
small ad ult o r teenager, or a passenge r who is
not si tt ing upr ight w ith their b ack against a
non -recli ned ba ck rest w ith their feet on the
vehicle floor in front of the sea t is on t he front
passenger seat
c> page 100, Proper seating
position for the driver.
If t he fron t passenger airbag dep loys, the
Federa l Standar d requ ires the airbag to meet
the "low risk" dep loyment criteria to red uce
the risk of injury th ro ugh interaction with the
airbag. "Low risk" dep loyment occurs in those .,.. •
•

-Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion .
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System.
-Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier carefully.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sens ing mat and can
cause injury in a crash .
Front airbags
Description of front airbags
The airbag system con provide supplemental
protection to properly restrained front seat occupants.
Fig. 122 Location of drive r airbag : in steerin g wheel
Fig. 123 Locat ion of front passenger 's a irbag: in the in­
s trum ent panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
Airbag system 121
(FMVSS) 208 as applicable at the time your
vehicle was manufactured . The safety belts
for the front seats have "pretensioners" that help to take slack out of the belt system. The
pretensioners are also activated by the elec­
tronic control unit for the airbag system .
The front safety belts also have load limiters
to help reduce the forces applied to the body
in a crash.
The a irbag for the driver is in the steer ing
wheel hub<=)
fig. 122 and the airbag for the
front passenger is in the instrument panel
r:::> fig . 123. The general location of the airbags
is marked '' AIRBAG" .
There is a lot you need to know about the air­
bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in­
fants and small children.
& WARNING
=
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide
only supplementa l protection .
- Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that everybody in your
ve­
hicle is properly restrained .
A WARNING
A person on the front passenger seat, es­
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the
front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
-
-
that deployment under these special 11-

122 Airbag sys te m
conditio ns is impossible in a ll co nceiva­
ble situati ons t hat may happen during
t h e usef ul lif e of your vehicle.
- The Adva nced Airbag System can deploy
in accor dance with the "low risk" opt ion
under the U.S. Federal Sta ndard if a child
that is heavier than the typical one-year old child is on the front passenger seat
and the othe r cond itions for airbag de­
ployment are met.
- For their own safety, all children, espe­
cially 1 2 yea rs and younger, sho uld a l­
ways ride p roperly rest rained for their
age and size.
Advanced front airbag system
Your veh icle is eq uipped wit h a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicab le at the time your vehicle was
manufactured.
The front Advanced Airbag System supp le­
ments the safety belts to provide addit iona l
protection for the driver's and front passeng ­
er's heads and upper bodies in frontal crashes.
The airbags inflate only in frontal impacts
when the vehicle dece lerat io n is high enough .
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of t he over­
all occupa nt restraint system in your ve hicle.
A lways remember that the airbag system can
on ly help to protect you, if you are s itting up­
r ight, wearing yo ur safety belt and wea ring it
p roperly. This is w hy you and yo ur passenge rs
must always be properly restrained , not just
beca use the law requires you to be.
The Advanced Airbag System in your veh icle
h as been cer tified to meet the " low r is k " re­
qu irements for 3 and 6 year -o ld children on
the passenger side and very small adu lts on
the driver side. The low risk deployment crite ­
ria are intended to he lp red uce the risk of in­
jury through interaction with the front airbag that can occur, fo r example, by be ing too cl
ose to the steering wheel and instrument
pane l when the airbag inflates .
In add ition, the system has been certified to
comply wi th the "s uppression" re qu iremen ts
of the Sa fe ty Standard, to turn off the front
airbag for infants 12 months o ld and younger
who are rest rained on the front passenger
seat in child restraints that are listed in the Standard
¢ page 140, Child restraints and
Advanced Airbags .
"Suppression" requires the front a irbag on the
passenger side to be turned off if:
- a child up to abo ut one year o f age is re ­
strained on the front passenger seat i n one
of the rear-fac ing or forward -facing infant
restraints listed in Federal Motor Vehicle
Safety Standard
208 with which the Ad­
vanced Airbag System in your vehicle was
cert ified . For a listing o f the ch ild res traints
that were used to certify your vehicle 's com­
plia nce w it h t he US Safety Standa rd
¢ page 140,
-we ight less than a threshold level stored in
the co ntrol uni t is de te cted on the fron t pas­
senger seat.
When a person is detected on the front pas­
senger seat, weighing more than t he total
we ight of a ch ild tha t is abou t 1 year old re ­
stra ined in one of the rear-fac ing or forward­
f acing infant res traints ( listed in Fede ral Mo­
tor Vehicle Safety Standar d
208 with which
the A dvanced Airbag System in your vehicle
was certif ied), the front airbag on the passen­
ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
whe n the electronic contro l unit detects a to­
ta l we ight on the front passenger seat that re ­
quires t he front airbag to be t urned off. If the
PASSENGER AIR BAG OFF light does not
come on, the front a irbag on the passenger
s ide has not been t urned off by the cont ro l
u ni t and ca n dep loy if the control un it senses
an imp act that meets the cond itions store d in
i ts memory.
If the total weight on the fro nt passenge r
seat is more than that of a typ ical 1 yea r-old , .,.

but less than the weight of a small adult, the
front airbag on the passenger side may deploy (the
PASSENG ER AIR BAG OF F light does not
come on).
For example, the a irb ag may depl oy if:
- a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld safety seats listed
¢ page 140),
-a ch ild who has outgrown child rest raints is
on the front passenger seat.
I f the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the center
of the inst rument panel w il l come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adult or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upr ight w ith
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the sea t is on the front passenge r seat.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the " low risk " deployment criteria to help re­
duce the risk of inj ury through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electronic control un it
¢ page 128.
Please be sure to read the important informa­
tion in the sections that fo llow and be sure to
heed a ll of the WARNINGS.
_& WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- If you are unrestrained, leaning forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in-
A irbag system 123
flates - even with an Advanced Ai rbag
¢page 117.
_& WARNING
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser ious ly injured and can be killed if
the front airbag inflates - even with an Ad­
vanced A irbag System .
-Although the Advanced Airbag System in your veh icle is designed to turn
off the
front airbag when a rearward-facing child restraint has been instal led on the
front passenger seat, nobody can abso­ lutely guarantee that dep loymen t is im ­
possible in all conceivable situations that
may happen during the usefu l life of your
veh icle.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, door, or roof.
- Never install a rearward facing child
safety seat on the front passenger seat
un less the
PA SSENGER AIR BAG OFF
light comes on and stays on . If the PAS­
SENGER AIR BAG OFF
light does not
come on and stay on the inflating a irbag
will hit the child safety seat or infant car­ rier w ith great force and w ill smash the
child safety seat and child against the
backrest, door or roof. Have the a irbag
system inspected immediately by your
author ized Audi dealer.
_& WARNING
If, in except iona l circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer fo r 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 ve ry near the instru-
ment panel.
