-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.
- Never let children play in or around the vehi­
cle.
- Never let passengers r ide in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
-Air circulation helps to reduce window fog­ ging . Stale air escapes to the outside
through vents in the trim panel. Be sure to
keep these slots free and open.
- 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

Tie-downs
App lies to vehicles: wit h tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-downs to secure your cargo properly
¢ page 118, Loading the luggage compartment.
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-lb
(4 .5 kg) object are about 20 times the normal
Driving safety
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 col­
lision like this.
A WARNING
-Weak, damaged or improper straps used to
secure items to tie-downs can fai l during hard
braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent items from shifting or flying forward as dan­
gerous missiles .
- When the rear seat backrest is folded down,
always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from flying forward as dangerous
missiles into the passenger compartment .
- Never attach a child safety seat tether strap
to a tie-down.

different tire speeds. For this rea­son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
&_ 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.
Wheels
-Only use tires that are more
than 6 years old when abso­ lutely necessary and drive
carefully when doing so.
-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/damage

tor
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. ..

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
t io ti res. These t ires have been tho rough ly tested
a n d been se lected specifically fo r yo ur model for
t he ir superb performance, road feel and handling
under a variety o f driving conditions. Ask your au­
thor ized Audi dealer for more details .
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire 's size designa ­
tion . The numera l represents the rat io o f the
tire's sidewall height in relat ion to its tread width
expressed in pe rc e ntage. Conventional t ir e s hav e
a height/w idth rat io of 60 or more.
The performan ce of low- aspect- ratio tire s is par­
ticularl y sensiti ve to imp roper inflat ion pres­
sure . It is therefore import ant that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and mainta ined . Tire pre ssure s shoul d
be checked at least once a month and alwa ys
befor e a long t rip
¢ page 215.
What you can do to avoid tire and rim
damag e
Low aspect rat io tires can be damaged more easi­
ly by impact with potho les, curbs, gull ies or
Wh eel s
ridges on the road, particular ly if the tire is un ­
deri nflated.
In orde r to min imi ze the occurrence of imp act
damage to the tires of yo ur vehicle , we recom­
mend that you observe the following preca u­
tions:
- Always ma intain recommended inflat io n pres­
sures. Check yo ur ti re pressure every 2,000
miles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith po tholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have th em inspected by th e nearest au ­
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect you r tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see . Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged , replace the tire as soon as pos­
sib le.
- These tires may wear more quickly than others .
- Please also remember that, while these tires
delive r responsive ha ndling, they may ride less
comfortably a nd make more noise than other
choi ces.
Reduced perfo rmance in winter /cold se ason
conditions
All tires are des igned for certai n purposes. The
low aspect ratio, ultra high performance tires
o rigi na lly installed o n your veh icle are intended
f or maximum dry and wet road per formance and
handling . They are not suitable for co ld, snowy or
icy weather conditions . If you drive under those
c ircumstances, you should equip your vehicle
with all-season or winter tires, which offer better
tract ion under those condi tions. We suggest you
use the recommended snow or all-season tires
spec ified for your veh icle, or their equiva lent .

Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
c::> page 205, fig. 167.
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 conditions on a specified gov ­
ernment test course.
For example, a tire graded 150 would wear one
and one half (11/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and may depart significantly from the norm due to
variations in driving 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 on 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
¢ &. .
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
c::> .&. .
222
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
No . 109 . Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING , ~ -
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
App lies to vehicles : wit h tire pressure mo nitori ng syste m
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires) .
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant- ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and ""

.... N
0 I­co .... <J:) Lil
.... <J:) ....
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and tire tread life,
and may affect the vehicle 's handling and stop ­
p ing ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat ion of the TPMS low tire p res­
sure telltale.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly . The TPMS ma l­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approx i­
mately one mi nute and then remain continuo usly
illuminated. This sequence will continue upon
subseq uent veh icle start-ups as long as the ma l­
function ex ists .
When t he malfunction indicator is ill uminated,
the system may not be ab le to detect or signal
l ow tire press ure as intended. TPMS ma lf u nctions
may occur for a var iety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always c heck the
