\.J ' -Therefore, always wear your safety belts and
make sure that everybody in your vehicle is
properly restrained.
- Always hold the steering wheel with both
hands on the outside of the steering wheel
rim at the 9:00 o'clock and 3:00 o'clock po­
sitions to help reduce the risk of personal in­
jury if the driver's airbag inflates .
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the steering wheel hub. Holding the steering
wheel the wrong way increases the risk of
severe injury to the arms, hands, and head if
the driver airbag deploys.
& WARNING
Objects between you and the airbag will in ­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds 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 struck
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 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 .
Airbag system
-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.
& 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" opt ion for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child with electrical capac­ itance greater than the combined capaci­
tance of a typical one-year old infant re­
strained in one of the forward facing or rear­
ward-facing child seats with which your ve­
hicle was certified is on the front passenger
seat and the other conditions for airbag de­
ployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing pos ition.
- 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, as
well as Canada Motor Vehicle Safety Standard ..,.

New tires or wheels
Audi recommends having all work on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace­ ment parts.
... New tires do not yet have the
optimum gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires .
... use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread pattern as possible on all four
wheels.
... use tires of the same construc­
tion, size (rolling circumference)
and the same tread pattern on
all four wheels.
... Do not replace tires individually.
At least replace both tires on the
same axle at the same time .

.,.Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size

vehicle with a tire/rim combina ­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase¢
& -
The spare tire* is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed - so only use the spare tire* tempo ­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all wheel drive
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­
son, in case of emergency, only
use a spare tire* that is the same ...

8,_ WARNING , -
-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
er vehicles -in some cases,
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 six years old when abso­
lutely necessary and drive
carefully when doing so.
Wheels
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve­ hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Tire wear
Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear .
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear. ..

and follow the important safe­
ty precautions in
q page 224,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and

Low aspect ratio tires
Your Aud i is f actory-equipped wi th low aspec t ra­
t io tires. The se tir es h ave bee n thor oughly te sted
and b een se lected s pecific ally fo r yo ur model fo r
their superb perfo rmance , road feel and hand ling
un der a va riety of driving conditions. As k yo ur au ­
thor ized Audi dealer for mo re details .
Th e low aspect ratio of these tires is indi cate d by
a nume ra l of
55 or less in t he tire's size desig na­
tion. The nume ra l r ep resents the rat io of t he
tire's sidewall he ight i n relat ion to its tread wi dth
expressed in pe rcentage. Conventional tires have
a heig ht/w idt h rat io o f 60 o r mo re.
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
be checked at least once a month and always
before a long trip~
page 221.

What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
l y by impact with potho les, curbs, gullies or
r idges on the road, particularly if the tire is un ­
der inflated.
In orde r to mi nimize the occurrence of impact
damage to the tires o f yo ur vehicle, we recom ­
mend that you observe the following preca u­
tions:
- Always maintain recommended inflation pres ­
sures. Check yo ur tire pressure every 2,000
m iles (3,000 km) and add a ir if necessary.
- Dr ive carefully on roa ds w it h potholes, deep
gullies o r ridges. The impact from dr iv ing
throug h or over such obstacles can damage
your t ires. Impac t with a curb may a lso ca use
damage to yo ur tir es.
- After a ny impact, immed iate ly inspect you r
tires or have them inspected by the nearest au ­
t horize d Aud i dealer . Replace a damage d tire as
soo n as poss ible .
- Inspec t your tir es ev ery 2,000 m iles (3,000 km)
for d amage and wear . Damage is no t always
easy to see . Da mage ca n lead to loss o f air and
un derinfla tion, w hich could eve ntually ca use
t ire f ailure. If yo u be lieve th at a tir e m ay h ave
been dam age d, rep la ce the tire as soon as pos ­
sible .
- These tire s may wea r mo re quick ly th an ot hers.
- Ple ase also remember th at , while t hese tires
delive r respo nsive h andli ng, they may rid e less
