A WARNING
r-=-
To help prevent poisonous 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 drive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
-
Close all windows,
-
Open all air outlets in the instrument pan-
el,
-Switch off the air recirculation,
-
Set the fresh air fan to the highest speed.
A WARNING
Always make sure that the doors, all windows
and the rear lid are securely closed and locked
to reduce the risk of injury when the vehicle is
not being used.
- After closing
the rear lid, always make sure
that it is properly closed and locked.
- Never leave your vehicle
unattended espe­
cially with the rear lid left open. A child
could crawl into
the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Nev er
let children play in or around the vehi­
cle.
- Never
let passengers ride in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
(D Tips
-Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
Safe driving
-The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar. The tire
pressure label lists the recommended cold
tire inflation
pressures for the vehicle at its
maximum capacity
weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter r:;. page 261.
Tie-down s
The luggage compartment is equipped with four
ti e-downs to secure luggage
and other items.

In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy 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 lbs
(4.5 kg) object
are about 20 times the normal
weight of the item. This means that the weight
of the item would suddenly be about
200 lbs (90 kg). You can imagine the injuries that
a 200 lbs (90 kg) item flying freely through the
passenger compartment could cause in a colli­
sion like this.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very
strong forces for peo­
ple riding in vehicles.

Safety belt s
The physical principles are simple. Both the vehi­
cle and
the passengers possess energy which var­
ies with vehicle
speed and body weight. Engi­
neers call this energy "kinetic energy."
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 significan t factor. If
the speed doubles from 15 to 30 mph (25 to 50
km/h), the energy increases 4 times!
B ecau
se the passengers of t his vehicle are not us­
ing
saf e ty belts~ fig. 146, they will keep moving
at the same speed the vehicle was moving just
before the crash, until something stops them -
here, the wall~ fig. 147.
The same principles apply to people sitting in a
vehicle
that is invo lved in a frontal co llision. Even
at city speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
(2,000 lbs, or 1,000 kg) or more. At higher
speeds, these forces are even greater.
People who do not use safety belts are also not
attached to thei r vehicle. In a frontal coll is ion
they will also keep moving forward at the speed
their vehicle was travelling just before the crash .
Of course, the laws of physics don't just apply to
frontal collisions , they determine what happens
in all kinds of accide nts and collisions .

Downloaded from www.Manualslib.com manuals search engine Safety belts
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed . Alway s wear your
safety belts!
Fig. 148 A driver not wearing a safety belt is violently
thrown forward
F ig .
149 A rear passenger not wearing a safety belt will fly
forward and strike
the driver
Unbelted occupants are not able to resist the tre­
mendous forces of impact by holding tight or
bracing themselves. Without the benefit of safe­
ty restraint systems, the unrestrained occupant
will slam violently into the steering wheel, in­
strument panel, windshield, or whatever else is
in the way q fig. 148. This impact with the vehi­
cle i
nterior has all the energy they had just be­
fore
the crash.
Never rely
on airbags alone for protection. Even
when
they deploy, airbags provide only additional
protection . Airbags are not supposed to deploy in
all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, in­
cluding
the driver, must wear safety belts cor­
rectly
in order to minimize the risk of severe in­
jury
or death in a crash.
182
Remember too, that airbags will deploy only
once
and that 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. Unbelted occupants can
also be thrown out of the vehicle where even
more severe or fatal injuries can occur .
I t is
also important for the rear passengers to
wear safety belts correctly. Unbelted passengers
in the rear seats endanger not only themselves
but also the driver and other passengers
~fig. 149. In a frontal collision they will be
thrown forward violently, where they can hit and
injure the driver and/or front seat passenger.
Safety belts protect
People think it's possible to use the hands to
brace
the body in a minor collision . It's simply
not true!
Fig. 150 Driver is correctly restrained in a sudden braking
man euver.
Safety belts used properly can make a big diffe r­
ence. Safety
belts help to keep passengers in
their seats, gradually reduce energy leve ls ap­
pli ed
to the body In an accident, and help prevent
the uncontrolled movement that can cause seri­
ous injuries . In addition, safety belts reduce the
danger of being thrown out of the vehicle.
Safety belts attach passengers to the car and give
them the benefit of being slowed down more
gently or "softly" through the "give" in the safety
belts, crush zones and other safety features engi­
neered into today's vehicles. By "absorbing" the
kinetic energy over a longer period of time, the
safety belts make the forces on the body more
"tolerable" and less likely to cause injury . .,..

Downloaded from www.Manualslib.com manuals search engine -Objects in the zone of a deploying airbag
can
become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold
things in your hands or on your
lap
when the vehicle is in use.
-Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors;
never
attach then to the doors or the wind­
shield; never place
them over or near or at­
tach them to the area marked ,.AIRBAG" on
the steering wheel, instrument panel or the
seat backrests; never place them between
these areas and you or any other person in
the vehicle.
- Never
attach objects to the windshield
above
the passenger front airbag, such as
accessory GPS navigation units or music
players. Such
objects could cause serious in­
jury
in a collision, especially when the air­
bags inflate.
- Never recline
the front passenger seat to
transport objects. Items can also move into
the deployment area of the side airbags or
the front airbag during breaking or in a sud­
den maneuver. Objects near the airbags can
fly dangerously through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
A WARNING
A person on the front passenger seat, espe­
cially infants and small children, will receive
serious injuries and can even be killed by be­
ing
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 un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag
System can deploy in
accordance with the "low risk" option under
-I
Airbag system
the U.S. Federal Standard if a child that is
heavier
than the typical one-year old child is
on
the front passenger seat and the other
conditions for airbag deployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position .
- For
their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag
System in compliance with United States
Federal Motor Vehicle Safety Standard 208 asap­
plicable at the time your vehicle was manufac­
tured.
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driver's and front passenger's heads and
upper bodies in frontal crashes. The airbags in­
flate only in frontal impacts when the vehicle de­
celeration 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 the overall occupant re­
straint system in your vehicle. Always remember
that the airbag system can only help to protect
you, if you are sitting upright, wearing your safe­
ty belt and wearing it properly. This is why you
and your passengers must always be properly re­
strained, not just because the law requires you to
be.
The Advanced Airbag
System in your vehicle has
been certified to meet the "low risk" require-
ments for 3 and 6 year-old children on the pas­
senger side and very small adults on the driver
side. The low risk
deployment criteria are intend­
ed to help reduce the risk of injury through inter­
action with the front airbag that can occur, for
example, by being too close to the steering wheel
and instrument panel when the airbag inflates.
In addition,
the system has been certified to
comply with the "suppression" requirements of .,..

for infants 12 months old and younger who are
restrained on the front passenger seat in child re­
straints that are listed in the Standard
¢ page 214, Child restraints and Advanced front
airbag system.
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up
to about one year of age is restrained
on the front passenger seat in one of the rear­
facing
or forward-facing infant restraints listed
in Federal Motor Vehicle Safety Standard 208
with which the Advanced Airbag System in your
vehicle was certified. For a listing of the chi ld

-When a person is detected on the front passen­
ger seat, weighing more than the total weight
of a child that is about 1 year old restrained in
one of the rear-facing or forward-facing infant
restraints (listed in Federal Motor Vehicle Safe­
ty Standard 208 with which the Advanced Air­
bag System in your vehicle was certified), the
front airbag on the passenger side may or may
not deploy.
The
PASSEN GER AIR BAG OFF light comes on
when the electronic control unit detects a total
electrical capacitance on the front passenger seat
that requires the front airbag to be turned off. If
the PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger side
has not been turned off by the control un it and
can depl oy ifthe control unit senses an impact
that meets the conditions stored i n its memory.
If the total electrical capacitance registered on
the front passenger seat is more than that of a
typical 1 year-old,
but less than the weight of a
small adult, the front airbag on the passenger
side may deploy (the PASSENGER AIR BAG OFF
light does not come on).
For example, the airb ag may dep lo y if:
- a small child that is heavier than a typical 1
year-old child is
on the front passenger seat
(regardless of whether the child is in one of the
child seats listed ~page 214),
194
-a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the overhead
console will come on and stay on.
If the front passenger airbag deploys, the Feder­
al Standard requires the airbag to meet the "low
risk"
deployment criteria to help reduce the risk
of injury through interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as defined
in the electronic control unit ¢page 199.
Always remember: Even though your vehicle is
equipped with Advanced Airbags, the safest place
fo r childre n is properly restrained on the back
seat. Please be sure to read the important infor ­
mation in the sections that follow and be sure to
heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
-
If you are unrestrained, leaning forward, sit·
ting sideways or out of position in any way,
your risk of injury is much higher.
- You will
also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even
with an Advanced Airbag~ page 188.
A WARNING
A child in a rearward-facing child seat instal­
led on the front passenger seat will be seri­
ously injured and can be killed if the front air­
bag inflates· even with an Advanced Airbag
System.
-Although the Advanced Airbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re­
straint has been installed on the front pas­
senger seat, nobody can absolutely guaran­
tee that deployment is impossible in all con­
ceivable situations that may happen during
the useful life of your vehicle.

combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should.
_&. WARNING
Changing the vehicle's suspension including
use
of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
-Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your vehicle.
- Never use tire-rim
combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front
seat
occupants.
Fig. 159 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel Q fig. 159, the
airbag for the passenger is at about the same
204
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy
in frontal collisions when the deployment
threshold stored in the control unit is met
Qpage 197, More important things to know
about front airbags.
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 overall 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 be ca use
t h e law requires you
to do so~ page 180, Gener­
al notes .
Remember too, airbags will deploy only once and
only in certain kinds 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
example when your vehicle strikes or is struck by
another after the first collision.
This
is just one of the reasons why an airbag is
not a substitute for the safety belt. The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly.
It is important to remember that while the sup­
plemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs and
80 lbs (18 kg and 36 kg) who are less than 4 ft 9
in (57 in/1.45 m) tall.
Fig. 169 Rear seat; chil d properly restrained in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4 ft 9 in (57 in/
1.45 m) tall and weigh about 80 lbs (36 kg).
Booster
seats raise these children up so that the
safety belt will pass properly over the stronger
parts of their bodies and the safety belt can help
protect them in a crash.
.. Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a
booster seat.
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap
belt must lie across the pelvis and never
across
the stomach or abdomen. Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
.. Secure unused safety belts on the rear seat
~page 217.
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restraint.
Child safety
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child's body in the right places. The routing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
ter seat is used . Children age 12 and under must
always ride in the rear seat.
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regardless
of how big the child is. Always remember that
children do not have the pronounced pelvic struc­
ture required for the proper function of lap belt
portion of the vehicle's three point lap and
shoulder belts. The child's safety absolutely re­
quires
that a lap belt portion of the safety belt be
fastened snugly and as low as possible around
the pelvis. Never let the lap belt portion of the
safety belt pass over the child's stomach or abdo­
men.
In a crash, airbags must inflate within a blink of
an eye and with considerable force. In order to do
its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­
pant moves forward into the airbag .
A vehicle
occupant who is out of position and too
close to the airbag gets in the way of an inflating
airbag.
When an occupant is too close , he or she
will be struck violently and will receive serious or
possibly even fatal injury.
In
order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children,
who must be in the front seat be­
cause
of exceptional circumstances, be properly
restrained and as far away from the airbag as
possible. By keeping room between the child's
body
and the front of the passenger compart­
ment, the airbag can inflate completely and pro­
vide
supplemental protection in certain frontal
collisions .

¢page 236.
~ Read the brake fluid level from the brake fluid
reservo ir ¢ fig. 188, ¢page 238, fig. 184. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The location
of the brake fluid reservoir can be
seen in the engine compartment illustration
¢page238.
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the brake fluid level falls considerably below
the "MIN" mark, the brake warning/indicator
light .. (U.S. models) I. (Canadian models)
will come on ¢ page 11. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected. Ifthe brake fluid level is too
low, the brake warning/indicator light will illumi­
nate. Contact an authorized Audi dealer immedi­
ately.

Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in
the brake system may result after ape­
riod of time. The boiling point of the brake fluid
will
also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed every
two years. Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the
brake fluid changed by your authorized Audi
dealer. Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
8._ WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
-Brake failure can result from old or inappro­
priate brake fluid. Observe these precau­
tions:
-Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with
your authorized Audi dealer to make
sure you are using the correct brake fluid.
The
correct type of brake f lui d is also ind i­
cated on the brake fluid reservoir .
- The
brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long.
This
can seriously affect the efficiency of
the brakes as well as your safety. This
could
result in an accident.

Battery
General information
The battery in your Audi does not need any main­
tenance under normal operating conditions. Audi
recommends having the electrolyte level check
by an
authorized Audi dealer or authorized Audi
Service Facility
when there are high outside tem­
peratures or when driving all day. The electrolyte
level should also be checked each time the bat­
tery is charged ~page 247.
Have the battery checked when you bring your ve­
hicle
in for an inspection . It is a good idea to re­
place
the battery if it is more than S years old.
Sometimes when the airbags deploy, the battery
will be disconnected from the vehicle electrical
system for safety reasons ~.&in Repair, care
and disposal
of the airbags on page 203.
Disconnecting the battery
The battery should not be disconnected. Several
vehicle functions (power windows, for
example)
will be lost when the battery is disconnected. The
functions must be reprogrammed after connect­
ing the battery. To avo id this, the battery should
only be disconnected from the vehicle electrica l
system when it is absolutely necessary.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time~ page 92. Some convenience
functions, su ch
as interior lighting or power seat
adjustment, may not be available under certain
circumstances. These convenience functions will
be available again once you switch
the ignition on
and start the engine.
Checking and Filling
Winter operation
A lot of stress is placed on the battery during
cold weather, which results in reduced starting
ability. Have the battery checked and recharged if
necessary
before the cold weather begins.
A WARNING
- Work on the battery requires expert know l­
edge. Contact an authorized Audi dealer or
authorized Audi Service Facility for informa­
tion regarding the vehicle battery. There is a
risk for chemical
burns or explosions.
- Never
open the vehicle battery. Do not try to
change the battery electrolyte level. Other­
wise explosive
gas will escape from the bat­
tery and increase the risk of an exp losion. ___ ....J

II WARNING -I
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise,
damage to
the vehicle and an accident
could result.
-For technical reasons, it is not
possible to use tires from oth­

you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than 6 years old when abso­
lutely necessary and drive
carefully
