Please remember - safety first!
The individual safety features of your vehicle can
work together as a system to help protect you
and
your passengers in a wide range of accidents.
These features cannot work as a system if they
are not always correctly adjusted and correctly
used.
This chapter contains important information,
tips, instructions and warnings that you need to
read and observe for your own safety, the safety
of your passengers and others. We have summar-
ized here what you need to know about safety
belts, airbags, child restraints as well as child
safety. Your safety is for us priority number 1. Al-
ways observe the information and warnings in
this section - for your own safety as well as that
of your passengers.
The information in this section applies to all
model versions of your vehicle. Some of the fea-
tures described in this sections may be standard
equipment on some models, or may be optional
equipment on others. If you are not sure, ask
your authorized Audi dealer.

ZA WARNING
— Always make sure that you follow the in-
structions and heed the WARNINGS in this
Manual. It is in your interest and in the in-
terest of your passengers.
— Always keep the complete Owner's Litera-
ture in your Audi when you lend or sell your
vehicle so that this important information
will always be available to the driver and
passengers.
— Always keep the Owner's literature handy so
that you can find it easily if you have ques-
tions.

Important things to do before driving
Safety is everybody's job! Vehicle and occupant
safety always depends on the informed and care-
ful driver.
For your safety and the safety of your passenger,
before driving always:
> Make sure that all lights and signals are operat-
ing correctly.
> Make sure that the tire pressure is correct.
> Make sure that all windows are clean and afford
good visibility to the outside.
> Secure all luggage and other items carefully
= page 50, > page 49.
> Make sure that nothing can interfere with the
pedals.
> Adjust seat and mirrors correctly for your
height.
> Make sure to use the right child restraint cor-
rectly to protect children > page 210, Child
safety.
> Sit properly in your seat and make sure that
your passenger do the same © page 46, Front
seats.
> Fasten your safety belt and wear it properly. Al-
so instruct your passenger to fasten his safety
belt properly > page 182.
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle, the driver as well as the driver’s abili-
ty to concentrate on the road without being dis-
tracted.
The driver is responsible for the safety of the ve-
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road > /\. Therefore:
> Do not let yourself be distracted by passenger
or by using a cellular telephone.
> NEVER drive when your driving ability is im-
paired (by medications, alcohol, drugs, etc.).
> Observe all traffic laws, rules of the road and
speed limits and plain common sense.
> ALWAYS adjust your speed to road, traffic and
weather conditions.

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 > page 178,
> Adjust the front passenger's seat properly
=> page 179,
> Wear safety belts properly > page 184,
> Always properly use the proper child restraint
to protect children > page 210.
In a collision airbags must inflate within the blink
of an eye and with considerable force. The sup-
plemental airbags can cause injuries if the driver
or the front seat passenger is not seated proper-
ly. Therefore in order to help the airbag to do its
job, it is important, both as a driver and as a pas-
senger 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 178, Correct
passenger seating positions. For details on the
operation of the seat adjustment controls
=> page 46.
It's especially important that children are proper-
ly restrained > page 210.
There is a lot that the driver and the passenger
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
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-
thorized 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 passenger from hitting parts of the inside
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

The PASSENGER AIR BAG OFF %; light in the
headliner tells you when the front Advanced Air-
bag on the passenger side has been turned off by
the electronic control unit.
Each time you turn on the ignition, the PASSEN-
GER AIR BAG OFF #¥; ON ® light will come on
for a few seconds and:
— PASSENGER AIR BAG OFF #¥; will come on if
the front passenger seat is not occupied,
— PASSENGER AIR BAG OFF 3; will come on if
the electrical capacitance measured by the ca-
pacitive passenger detection system for the
front passenger seat equals the combined ca-
pacitance of an infant up to about one year of
age and one of the rearward-facing or forward-
facing child restraints listed in Federal Motor
Vehicle Safety Standard 208 with which the Ad-
vanced Airbag System in your vehicle was certi-
fied. For a listing of the child restraints that
were used to certify your vehicle's compliance
with the U.S. Safety Standard = page 212.
— PASSENGER AIR BAG OFF 3; will come on if
there is a small child or child restraint on the
front passenger seat,
— PASSENGER AIR BAG ON @ will go off if the
front passenger seat is occupied by an adult as
registered by the capacitive passenger detec-
tion system > page 200, Monitoring the Ad-
vanced Airbag System.
The PASSENGER AIR BAG OFF 3%; light comes on
when electrical capacitance registered on the
front passenger seat is equal to or less than the
combined capacitance of a typical 1 year-old in-
fant and one of the rearward-facing or forward-
facing child restraints listed in Federal Motor Ve-
hicle Safety Standard 208 with which the Ad-
vanced Airbag System in your vehicle was certi-
fied.
If the total electrical capacitance registered on
the front passenger seat is more than that of a
typical 1 year-old child but less than the weight
of a small adult, the front airbag on the passen-
ger side can deploy (the PASSENGER AIR BAG
OFF 3%; light does not come on).
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 electronic
control unit and can deploy if the control unit
senses an impact that meets the conditions stor-
ed in its memory.
For example, the airbag may deploy if:
—asmall child that is heavier than a typical 1
year-old child is on the front passenger seat (re-
gardless of whether the child is in one of the
child safety seats listed > page 212), or
—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 comes on in
the headliner and stays on.
If the front passenger airbag deploys, the Federal
Standard requires the airbag to meet the “low
risk” deployment criteria to reduce the risk of in-
jury 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 200, PASSEN-
GER AIR BAG OFF $; ON ® light.
Always remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal collision. The air-
bag could greatly reduce the effectiveness of the
child restraint and even seriously injure the child
during inflation.

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.
— The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
— Forward-facing child seats installed on the
front passenger's seat may interfere with
the deployment of the airbag and cause seri-
ous personal injury to the child.

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.

ZA\ 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
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.
— For its own safety, a child should always ride

properly restrained for its 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 (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.

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
194
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
the Safety Standard, to turn off the front airbag
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 212, 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 child
restraints that were used to certify your vehi-
cle's compliance with the US Safety Standard
=>page 212,
— When a person is detected on the front passen-
ger seat that has an electrical capacitance that
is more than the total electrical capacitance of
a child that is about 1 year old restrained in one
of the rear-facing or forward-facing infant re-
straints (listed in Federal Motor Vehicle Safety
Standard 208 with which the Advanced Airbag
System in your vehicle was certified), the front
airbag on the passenger side may or may not
deploy.

The PASSENGER 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 3%; light does not
come on, the front airbag on the passenger side
has not been turned off by the control unit and
can deploy if the control unit senses an impact
that meets the conditions stored in 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 airbag may deploy if:
—asmall child that is heavier than a typical 1
year-old child is on the front passenger seat (re-
gardless of whether the child is in one of the
child seats listed > page 212),
—a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger airbag is turned off, the

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.
— The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door, or roof.
— Ifyou must install a rearward facing child
safety seat on the front passenger seat be-
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF %; light does not
come on and stay on have the airbag system
inspected by your Audi dealer.


ZA 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

ZA WARNING
If, in exceptional circumstances, you must in-
stall 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 manu-
facturer for use on a front seat with a pas-
senger front and side airbag.
— Never put the forward-facing child restraint
up against or very near the instrument pan-
el.
— Always move the front passenger seat to the
highest position in the up and down adjust-
ment range and move it back to the rear-
most position in the seat's fore and aft ad-
justment range, as far away from the airbag
as possible, before installing the forward-
facing child restraint.

Child safety

Child safety
Important information
Introduction
The physical principles of what happens when
your vehicle is in a crash apply also to children
=> page 183, What happens to occupants not
wearing safety belts?. But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully developed,
they require restraint systems especially de-
signed for their size, weight, and body structure.
Many countries and all states of the United
States and provinces of Canada have laws requir-
ing the use of approved child restraint systems
for infants and small children.
Ina frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13 lbs (6 kg)
infant will be more than 20 times the weight of
the child. This means the weight of the child
would suddenly be more than 260 lbs (120 kg).
Under these conditions, only an appropriate child
restraint properly used can reduce the risk of seri-
ous injury. Child restraints, like adult safety belts,
must be used properly to be effective. Used im-
properly, they can increase the risk of serious in-
jury in an accident.
If you must install a child restraint on the front
passenger seat in exceptional circumstances, be
sure to read and heed the important information
and warnings > page 190. Infants and other chil-
dren who are properly restrained in an appropri-
ate child restraint that is for their size and age
can benefit from the protection that supplemen-
tal side airbags provide in some kinds of crashes.

Consult the child safety seat manufacturer's in-
structions in order to be sure the seat is right for
your child's size > page 213, Important safety
instructions
for using child safety seats. Please
be sure to read and heed all of the important in-
formation and WARNINGS about child safety, Ad-
vanced Airbags, and the installation of child re-
straints in this chapter.
There is a lot you need to know about the Ad-
vanced Airbags in your vehicle and how they work
when infants and children in child restraints are
on the front passenger seat. Because of the large
amount of important information, we cannot re-
peat it all here. We urge you to read the detailed
information in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans-
porting children on the front passenger seat.
Please be sure to heed the WARNINGS - they are
extremely important for your safety and the safe-
ty of your passengers, especially infants and
small children.

ZA WARNING
All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly re-
strained child could be injured by striking the
interior or by being ejected from the vehicle
during a sudden maneuver or impact. An un-
restrained or improperly restrained child is al-
so at greater risk of injury or death through
contact with an inflating airbag.

ZA WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or
even killed when an airbag inflates. A child in
a rearward-facing child safety seat installed
on the front passenger seat will be seriously
injured and can be killed if the front airbag in-
flates.
— 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, center armrest, or
door.

The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
G) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the “ symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.

CG) Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.
— Using snow chains that add more than 0.53
in (13,5 mm) of height can severely damage
the wheel housings and other vehicle com-
ponents.
@) Tips
When using snow chains, it may be advisable
to limit the ESC > page 87.
ee cil med
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 250.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an
authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
