2017 AUDI S3 SEDAN tires

Driving safety
-Close the power top*,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
.&, WARNING
-
Always make sure that the doors, all win­
dows, the power roof*, the power top* and
the rear lid are securely closed and locked to
reduce the risk of injury when the vehicle is
not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked.
- 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 ride in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
(D Tips
- 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
c:> page 336.

· 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
c:> page 253, 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
weight of the item. This means that the weight
of the item would sudden ly 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.
.&, WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail 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.

Wheels and Tires
General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
~ Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
~ Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(i}) Note
-Please note that summer and
winter tires are designed for
the conditions that are typical i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
328
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the r ims
does not have sufficient corro­
sion protection for th is and
could be permanently dam­
aged by road salt or similar
substances.

comparisons among tires. The
UTQG is not a safety rating and not a guarantee that a tire will
last for a prescribed number of
miles (kilometers) or perform in a
certain way. It simply gives tire
buyers additional information to
combine with other considera ­
tions, such as price, brand loyalty
and dealer recommendations. Un ­
der UTQG, tires are graded by the
tire manufacturers in three areas:
treadwear, traction, and tempera ­

U.S. DOT Tire Identification
Number (TIN)
T his is the tire's "serial number".
It begins with the letters "DOT"
and indicates that the tire meets
all federal standards. The nex t
two numbers or letters indicate
the plant where it was manufac­
tured, and the last four numbers represent the week and year of
manufacture. For example,
DOT ... 2216 ...
means that the tire was produced
in the 22nd wee k of 2016. The
other numbers are marketing co­
des that may or may not be used
33 4
by the t ire manufacturer . This in­
formation is used to contact con­
sumers if a tire defect requ ires a
recall.

and dividing
by two.
Vehicle normal load on the tire
means that load on an individual
tire that is determined by d istrib­
ut ing to each axle its share of the
curb weight, accessory weight,
and normal occupan t weight (dis­
tr ibuted in accordance with
¢ ta­
ble on page 338) and d ividing by

New tires or wheels
Aud i recommends having all work on tires or
wheels performed by an authorized Audi dealer
or author ized Audi Se rvice Facility . These fac ili­
ties have the proper know ledge and are equipped
with the required too ls and replacement parts.
• New tires do not yet have the optimum grip­
ping properties. Drive caref ully and at moder ­
ate speeds for the first 350 mi les (500 km)
with new tires.
• Only use tires w it h the same design, size (roll­
i ng c ircumference) and as close to the same
tread patter n as poss ible on all four wheels .
• Do not replace t ires individua lly. At least re­
pla ce both t ires on the same axle at the same
t ime .
• Audi recommends that you use Aud i Original
Tires . If you wou ld like to use different tires,
please note that the tires may perform differ­
ently even if they are the same
si ze ¢ ,& .
• If you would like to equip your veh icle w ith a
tire/rim comb inat ion that is different from
what was installed at the factory, consult w ith
an aut horized Aud i dea ler o r authorized Audi
Se rvice Facility befo re making a
purchase ¢,& .
The spare tire* is different from the regular tires
insta lled on the veh icle
-for example, if w inter
tires or w ide tires a re ins talled
-so only use the
spa re ti re* tempo rar ily in case of emergen cy and
d rive caref ully wh ile i t is in use . It should be re ­
p laced w it h a regular t ire as soon as possib le.
Applies to: vehicles with all wheel drive: all four
wheels must be eq uipped w ith tires that are the
same brand and have the same construc tion and
tread pattern so that the drive system is not
damaged by different wheel speeds. For this rea­
son , in case of eme rgency, only use a spare tire*
Wheels
that is the same circ umfe rence as the regular
tires.
A WARNING
--On ly use t ire/rim comb inations and suitab le
wheel bo lts that have been approved by
Aud i. Otherwise, damage to the vehicle and
a n accident could res ult.
-For technical reasons, it is not possible to
use t ires from other ve hicles
-in some cas­
es, yo u cannot even use tires from the same
veh icle model.
-Make sure that the tires you select have
e nough clearance to the veh icle. Rep lace­
ment tires should not be chosen s imply
based on the nomina l size, because ti res
wit h a differe nt constru ction can diffe r
g reatly even if they are the same size . If
there is no t enough clearance, the tires or
the vehicle can be damage d and this can re­
duce dr iving safety and increase the risk of
an accident.
-On ly use t ires that are more than s ix years
old when absolutely necessa ry and drive
carefully when doing so.
- Do not use run -flat tires on your vehicle . Us­
ing them when not perm itted can lead to
veh icle damage or accidents.
- If you install wheel covers on the vehicle, make sure they allow enough air circulation
to cool the brake system. If they do not, t his
could increase the risk of an acc ident.
