162 Airbag system
old child is on the front passenger seat
and the other conditions for airbag de­
ployment are met .
- Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­ cially 12 years and younger, should al­
ways 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 applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
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 deceleration 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 over­
all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you , if you are sitting up­
right, wearing your safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re ­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side . The low risk deployment crite­
ria are intended to help reduce the risk of in­
jury through interaction 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 restraints that are listed in the
Standard
¢ page 180, Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned
off if:
- a child up to about one year of age is re­
strained 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 Ad­
vanced Airbag System in your vehicle was
certified . For a listing of the child restraints
that were used to certify your vehicle's com­ pliance with the US Safety Standard
¢page 180,
-weight less than a threshold level stored in
the control unit is detected on the front pas­
senger seat.
When a person is detected on the front pas­
senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing or forward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­
quires 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
unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory.
If the total weight 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).
ll-

-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rear-facing child safety seat in
a rear seating position and have the air­
bag system inspected immediately by
your Audi dealer.
_& WARNING
If, in exceptional 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 for use on a front seat
with a passenger front and side airbag.
- Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be
adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Child Safety 1 79
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the 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 "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­ cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger 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 for­
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight -sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight -sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the ..,.

p ill ar
Tire pressure genera lly refers to the amount
of air in a t ire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna·
tional measur ing unit and in pou nds pe r
squa re inc h (PSI). Tire pressure is based in
par t on the vehicle's desig n and load limit -
the greatest amoun t of weight that the vehi·
cle can carry safe ly and the t ire size . The prop·
er tire pressure is freq uently referred to as the
" recommended cold tire inf lation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The t ire p ressu re is higher when the tire
h as wa rmed up tha n when it is "cold ." It is the
in flat io n pressu re i n a "cold" tire that counts.
Th erefore, you shou ld neve r let air ou t of a
warm tire to match " co ld tire inflat ion pres­
sure" recommendations . The t ires wo uld then
be underinflated and could fail su ddenly .
M ain taining p roper t ire pr essu re is one of the
most im po rt an t th ings you ca n d o to he lp
avoid sudden tire failure. Underin fla ted t ires
a re a ma jo r cause of s udden tire failure. Keep·
i n g tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

258 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

F ig. 206 Rotat ing t ires for more ev en wea r
Tread Wear Indicator (TWI)
The o rigi na l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 205 running across the tread. Depend ­
i ng on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different fig ures may apply in o ther countries
c::> & .
Tire p ressure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 254.
Driving style
Driving fast aro und curves, heavy acce leration
and hard braking increase tire wear.
Rotating tires for more even wear
F or all four tires on your ve hicl e to h ave the
same service life, we recommend that the
front and rear t ires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service inte rva ls o utlined in your
Ma intenance and Warranty Book let .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 206.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 278 .
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avoid excessive wear on steering, suspension
and t ires. A whee l m ust also be reba lanced
when a new tire is insta lled.
Incorrect wheel alignment
Incor rect wheel alig nment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop .
All-wheel driv e
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type .
For details see
c::> page 202 . ..,.

26 2 T ire s and wheel s
-All four wheels must be fitted with radia l
t ires of the same type, size (roll ing c ir­
cumference) and the same tread pattern.
Driv ing with different tires reduces veh i­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
t ir es that are mounted on the veh icle -
for example with wi nter tires - on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the no r­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are drive n
faster than their rated speed can fail
sudden ly.
- Overloading ti res cause heat build- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un­
derinflated.
- For technical reasons it is not a lways
poss ible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel tr im discs on the ve­
hicle whee ls, make sure that the air flow
to the brakes is not blocked . Reduced air­
flow to the brakes can them to overheat,
increasing stopping d istances and caus­
ing a collision.
- Run flat t ires may on ly be used on
vehicles that we re eq uipped w it h them
at the f acto ry. The vehicle must have a
chassis des igned for r un flat t ires . Incor­
rect use of run flat tires can lead to vehi­
cle damage or acc idents . Check with an
authorized Audi dealer or t ire specia list
to see if your vehicle can be equipped
with run flat t ires. If run flat tires are
used, they must be installed o n all four
wheels. Mix ing tire types is not permit­
ted. (D Note
- For technical reasons, it is not generally
poss ible to use the wheel rims from oth­
er veh icles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is diffe rent from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire w it h the
ti re mat ching the othe rs on your vehicle
as soon as possi ble.
- Never d rive without the valve stem cap.
T he v alves co uld get damaged.
@ For the sake of the environment
Dispose of o ld tires in accordance w ith the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Tra ction AA A B (
- Temperature ABC
Quality grades can be found where applicab le
on the tire s ide wall between tread shoulder
and maximum section width
¢ page 259,
fig . 207 .
For example: Tread wear 200 , Traction AA ,
Temperature A .
All passenger car ti res must conform to Feder­
al Safety Requirements in add ition to these
grades .
Tread wear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions o n a specified
government test course.
F o r example, a tire graded
150 wo uld wear
one and one ha lf
(11/2) times as well on the
government course as a ti re graded
100.

The relative perform a nee of ti res depends
upon the actua l conditions of their use, how ­
ever, and may depart sign ificantly from the
norm due to var iat ions in dr iving habits, serv­
ice practices and differences in road character­
istics and climate .
Trac tion
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as measured under controlled cond itions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢,&. .
Temp erature
The temperature grades are A (the h ighest),
B, and
C, representing the t ire's resistance to
the generat ion of heat and its ability to dissi ­
pate heat when tested under controlled condi­
tions on a specified i ndoor laboratory test
wheel.
Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden ti re fa ilu re ¢ ,&. .
The grade
C corresponds to a level of perform ­
ance which all passenger car tires must meet
u nder the Federa l Moto r Veh icle Safety Stand­
a rd No.
1 09. G rades Band A represent h igher
l eve ls of perfo rmance on the laboratory tes t
wheel than the m inimum required by law .
A WARNING
The traction grade assigned to this ti re is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering, hydrop lan ing or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es­
tablished for a t ire that is p roperly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
-
Tire s an d wheel s 263
separately or in combinat ion, can ca use
heat bui ldup and possible tire failure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F (7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true winter o r "snow" tires, those
with very deeply cut tread. These tires should
o nly be used in pairs and be installed o n all
four wheels . Make sure you purchase snow
t ires that are the same size and construction
type as the other tires on you r vehicle.
Your vehicle is equipped with all-wheel drive,
th is w ill improve traction during winter driv­
i ng, even with the standa rd tires . However, we
strong ly recommend that you always equip all
fo ur wheels on you r vehicle wit h corre ct ly fit­
ted winter tires or all-season t ires, when win­
te r road cond itions are expected . This also im ­
proves the veh icle's braking per formance and
reduces stopping dista nces.
Summe r tires provide less grip on i ce and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur wheels .
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire size s. Use
o nly rad ial w inter t ires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0 .157 inch
(4 mm) .
Only drive w ith w inter t ires under w inter con­
dit ions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
whee l
¢page 259.
Please a lways remember that winter tires may
have a lowe r speed rating than the tires o rigi -
nally installed on your vehicle at the time it .,.
