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 rood without being dis­
tracted.
The driver is responsib le for the safety of the ve ­
hicle and a ll of its occupants. If your ability to
drive is impa ired, safety risks for everybody in the
vehicle increase and you a lso become a hazard to
everyone else on the road
¢ _&. . Therefore:
.. Do not let yourse lf be distracted by passenge rs
or by using a cellular telephone .
.. NEVER drive when your driving ability is im­
paired (by med ications, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .

A WARNING
Impaired driv ing safety increases the risk of
ser ious personal inju ry and death whenever a
vehicle is being used.
Correct passenger

Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving .
Fig. 219 Correct seating pos ition
F or your own s afety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver 's seat to the following
position:

A WARNING
-
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in­
jured by an airbag as it unfolds. To help re­ d uce the risk of serious personal injury:
- Always ad just the driver's seat and the
steer ing whee l so that there are at least
10 inc hes (25 cm) between you r breastbone
and the steering wheel.
- Always hold the steering wheel on the out­
side of the steering wheel r im with your
hands at the 9 o'clock and 3 o' clock posi­
tions to help reduce the risk of personal in­
ju ry if the driver's airbag inflates.
- Never hold the stee ring wheel at the
12 o' clock position o r with you r hands at
o ther posi tions ins ide the s teer ing whee l
rim or on the steering wheel hub. Holding
the steering wheel the wrong way can cause
serio us injuries to the hands, arms and head
if the dr iver's airbag dep loys.
- Pointing the steering wheel toward your
face decreases the ability of the supplemen­ tal driver's airbag to protect you in a coll i­
sion.
- Always sit in an upright position and never
lean aga inst or place any part of your body
too close to the area where the airbags are located .

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 ~ page 253,
.,. Adjust the front passenger's seat properly
~page 254,
.,. Wear safety belts properly ~page 263,
.. Always properly use the proper child restraint
to protect children¢
page 291.
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 253, Correct
passenger seating positions .
For details on the
operation of the seat adjustment controls
¢page 56.
It's especially important that children are proper­
ly
restrained ¢ page 291.
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
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 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

about children and Advanced Airbags
¢page 291 .
Even though yo ur vehicle is equ ipped with an Ad­
vanced Airbag System, make certain that a ll chil­
dren, especially those 12 years and younger, al ­
ways ride in the back seat proper ly restrained for
their age and size. The airbag on the passenger
side makes the front seat a potentially dangerous
place for a child to ride. The front seat is not the
safest place for a child in a forward-facing child
safety seat. It can be a very dange rous place for
a n in fant or a child in a rearward-fac ing seat.
The Advanced Airbag System i n your veh icle has
been certified to comply with the requirements
of United States Federal Motor Vehicle Safety
Standa rd (FMVSS) 208, as well as Canada Motor
Ve hicle Safety Standa rd (CMVSS) 208 as applica ­
b le at the time your veh icle was man ufactu red.
According to requirements, the front Advanced
Airbag System on the passenger side has been
certified for "suppression" for infants of about 12 month old and younger and for "low risk de­
p loyment" for children aged 3 to 6 years o ld (as
defined in the standard).
The
PASSENGER AIR BAG O FF ~ ; 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.

pacitance of an infant up to about one year of
age and one of the rearward-facing or forward ­
facing child restra ints listed in Federal Motor
Vehicle Safety Standard (FMVSS) 208 with
wh ich the Advanced Airbag System in your ve hi­
cle was certified. Fo r a listing of the child re ­

- PASSEN GER AIR BAG OFF ~; will come on if
there is a small chi ld or child restraint on the
front passenger seat
- PASSENGER AIR BAG ON @ will come on if the
front passenger seat is occupied by an adu lt as
registered by the capacitive passenger detec­
tion system
¢ page 281, Monitoring the Ad­
vanced Airbag System.
The PAS SEN GER AIR BAG OFF ~; light comes on
when e lectrica l 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 restra ints listed in Federal Motor Ve­
hicle Safety Standard (F MVSS) 208 with wh ich
t h e Advanced Airbag System in you r vehicle was
ce rtified.
If the total electr ical capacitance reg istered on
t h e front passenger seat is mo re than that of a
typ ica l 1 yea r-old ch ild but less than the weight
of a sm all adul t, the front airbag on the passen ­
ger side can deploy (the
PASSENGER AIR BAG
OFF
If the PASSENGER AIR BAG OFF~; light does
not come on, the fro nt airbag on the passenge r
side has not been t urned off by the e lectronic
contro l unit and can deploy if the contro l unit
senses an impact that meets the conditions stor ­
ed in its memory.
For example , th e ai rb ag ma y deplo y if:
- a small c hild that is heav ier than a typ ica l 1
year -o ld child is on the front passenger seat
(regard less of whethe r the child is in one of t he
child sa fe ty seats
listed ¢ page 293), or
- a child who has outgrown c hild rest raints is on
the front passenger seat .
If the front passenge r a irbag is tu rned off, the
PASSENGER AIR BAG OFF ~; light comes on in
t h e headliner a nd stays o n.
If the front passenger a irbag deploys, the Feder­
al Standard requ ires t he a irbag to meet the " low
r isk" deployment cr ite ria to redu ce the r isk of in­
j u ry throug h interact ion w it h t he airbag. "Low
risk" deployment occurs in t hose crashes that
take place at lower decelerations as defined in
..,.

Airbag syste m
-Never hold the steering whee l at the 12
o'clock pos it ion or w ith your han ds any­
where inside the steering wheel or on the steering wheel hub. Holding t he steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and head if
the d river a irbag deploys.
A WARNING
Objects between you and the a irbag w il l in­
crease the risk of inj ury in a crash by interfer­
ing w ith the way the airbag unfo lds and/or by
being pushed into you as the airbag inflates .
- Always make sure nothing is in the front air-
bag deployment zone that could be str uck
by the airbag when it inflates.
-
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de ­
ploys and cause serious persona l injury .
- Never hold th ings in your hands or on your
lap when the vehicle is in use.
- Never place accessor ies or other objec ts
(s uch as c up ho lders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, o r 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 p lace them between
these a reas and yo u or any other person in
the vehicle.
- Never attach objects to the w indshield
above the passenger front airbag, s uch as
accessory GPS navigation uni ts or mus ic
players . S uch objects could ca use serio us 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 a irbags or
the front a irbag during breaking o r in a sud­
den maneuver. Objects near the airbags can
fly dangerous ly through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
274
A WARNING
A person on the front passenger seat, espe­
cially infants and small ch ildren, wi ll receive
serious in juries and can even be k illed by be­
ing too close to the airbag when it inflates .
- Although the Advanced Airbag System in your veh icle is designed to turn off the front
passenger airbag if an infant o r a small child
is on the fron t passenger sea t, nobody can
absolu tely guarantee tha t deployment un­
de r these specia l condi tions is impossible in
all conceivable situations that may happen
during the useful life of yo ur vehicle.
- The Advanced Airbag System can dep loy in
accordance with the
,. low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child w ith electrical capac­
itance greater than the combined capac i­
tance of a typical one-year o ld infant re­
strained in one of the forward facing or rea r­
ward-facing chi ld seats with which yo ur ve­
hicle was certified is on the front passenger
seat and the o ther conditions for airbag de-
ployment are me t.
- Accident s tatisti cs have shown th at children
are generally safer in the rear seat are a than
in the front seat ing pos ition.
- For their own s afety, all ch ildren, especi ally
12 years and younger, should alw ays ride in
the back proper ly restrained for their age
and size .

The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.16 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 .
(D 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
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
"'Only install snow chains on the rear 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 (SO km/
h). Note 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.
Use
fine-mesh snow chains. They must not add
more than 0 .53 in (13.S mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires .
_& WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle

control, which increases the risk of an
accident.
@ Note
-Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them . Remove the wheel covers*
first. Use coated snow chains.
-Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch the offroad mode on <=>

Low-profile tires
App lies to: ve hicles with low -profile tires
Compared to other tire/rim combinat ions, low­
profile tires offer a wider tread surface and a
l arger r im diameter with shorter tire sidewalls.
This results in an agile dr iv ing style. However, it
may reduce the leve l of comfort and increase
road noise when driving on roads in poor condi­
tion .
L ow -profile tires can become damaged more
quickly than standard tires when driving over
l arge bumps, potholes, manhole covers, and
curbs . Therefore, it is particular ly important to
maintain the correct tire pressure<=>
page 335 .
To reduce the risk of damage to the tires and
rims, drive very carefu lly on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. Fo r 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 immediate ly by
an authorized Audi dealer or authorized Audi
Service Facility .
Lo w-profile tires can wear out faster than stand­
ard tires.

Uniform tire quality grading
-Tread wear
-Traction AA ABC
-Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width <=>
page 326, fig. 266.
For example: Tread wear 200 , Traction AA, Tem­
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled cond it ions on a specified gov ­
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as we ll on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual cond it ions of the ir use, however, and
may depa rt significantly from the norm due to
variations in driv ing habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA , A, Band
C. Those grades represent the tire's
ability to stop o n wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c:>,& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
