wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the w inter. The brakes
must be dried first w ith a few careful brake
applications.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
funct ion.
- To reduce the risk of damage to the rims
and tires, compare the width between the
whee ls on your vehicle w ith the distance be­
tween the g uide rails in the car wash .
- To red uce the risk of damage, compare the
height and width of yo ur vehicle with the
Care and cleaning
height and w idth of the inside of the car
was h.
- T o prevent paint damage, do not wash the
vehicle in direct sunlight.
- To reduce the ris k of damage to the sur face,
do not use insect remov ing sponges, kitchen
sponges o r similar items.
- Matte finish painted veh icle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted w ith matte
finish paint. The paint could be damaged
when the stickers or magnets are re­ moved.
@ For the sake of the environment
Only wash the vehicle in facilities spec ially de­
s igned for that purpose. Th is w ill reduce the
r isk of dirty water contaminated w ith oil from
entering the sewe r system.
Cleaning and care information

Wheels and Tires
General information
.,.Che ck 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.
"'Protec t your tires from oil,
grease and fuel.
.,.Ma rk 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.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold tem­
peratures, 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 rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

Uniform Tire Quality Grading
is a tire information system devel­
oped by the United States Nat ion­
al Highway Traffic Safety Adminis ­
tration (NHTSA) that is designed
to help buyers make relative com­
parisons among tires . The UTQG is
not a safety rating and not a guar­
antee tha t a tire will last for a
prescribed number of miles (ki lo­
meters) or perform in a certain
way. It simply gives tire buyers
additional information to com­
bine with othe r considerations,
s u ch as price , brand loyalty and
dealer recommendations . Under
UT QG,
tir es a re grade d by the tire
manu factu rers in three areas :
treadwear, traction, and tempera­
ture resistance. The UTQG infor­ mation on the tires, mo lded into
the sidewalls .
U.S. DOT Tire Identification
Number (TIN)
This is the tire's "serial number" .
It beg ins with the letters "DOT"
and indicates that the tire meets
all federal standa rds. The next
two numbers or letters indicate
the plant where it was manufac ­
tured, and the last four numbers
represent the wee k and year o f
manufacture . For example ,
Wheels
DOT ... 4514 ...
means that the tire was produced
in the 45th week of 20 14. T he
other numbers are ma rketing co­
des that may or may not be used
by the tire manufact urer. Th is in­
formation is used to contact con­
sumers if a tire defect requ ires a
recall.

gage load plus 150 lbs. (68 kilo­
grams) times the vehicle's des ig ­

tire that is determined by distrib­
ut ing to eac h ax le its share of t he
maximum loaded vehic le weight

Vehicle normal load on the tire
means that load on an individual
tire that is determined by d istrib­
uting to each ax le its share of the
curb weight , accessory weight,
and norma l occupant weigh t (dis­
tributed in acco rdance with¢

New tires or wheels
Audi recommends having all wo rk
on tires or wheels performed by
an authorized Audi dea ler or au­
thorized repair fac ility. These fa­
cilities have the proper knowledge
and are equipped with the re­
quired tools and replacement
parts.
.,. New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds fo r the first 350 miles
(500 km) with new tires .
.,. Use tires of t he same constr uc­
tion, size (rolling c ircumference)
and as close to the same tread pattern as possible on all four
wheels.
2 4 2
.,.Do not replace tires individ ually .
At least re place both t ires on the
same axle at the same time.
.,. A udi recommends that you use
Aud i O riginal equipment tires . If
you wo uld li ke to use different
tires, please note that the tires may perform d ifferently even if
they are the same s ize
c:> &. -
.,. If you would like to equip you r
vehic le with a tire/rim combina­
tion that is different from what
was installed at the facto ry, con ­
sult w ith an authorized Aud i
dealer or authorized repair facili­
ty be fore making a purchase
¢ .&_ .
The spare tire* is d ifferent from
the regular t ires installed on the
vehicle -for example, if winter
tires or wi de tires are installed -
then only use the spare tire* tem­
porar ily in case of emergency and
drive carefully while it is in use . It
s h o u ld be replaced w ith a regular
tire as soon as poss ib le.
On
all wheel drive ve hic les, all
four wheels must be equipped
w ith 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
circumference as the regular tires.
A 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 6 years old when abso-
Wheels
lutely necessary and drive
carefully when doing so.
-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/damage

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.
