Wheels

@) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the 44 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
Use fine-mesh snow chains. They must not add
more than 0.53 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.
@) Note
Snow chains can damage the rims and wheel
covers* if the chains come into direct contact
with them. Remove the wheel covers* first.
Use coated snow chains.
@ Tips
When using snow chains, it may be advisable
to limit the ESC > page 114.

Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface anda
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 245.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 236, fig. 165.
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

Care and cleaning


follow the instructions from the car wash
operator.
—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 winter. This in-
creases the risk of an accident. The brakes
must be dried with a few careful brake appli-
cations.

@) Note
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing matte finish painted vehicle
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 components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
—To reduce the risk of damage to the rims
and tires, compare the width between the
wheels on your vehicle with the distance be-
tween the guide rails in the car wash.
—To reduce the risk of damage, compare the
height and width of your vehicle with the
height and width of the inside of the car
wash.
(*) For the sake of the environment
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.

components, refer to the following tables. The
information contained there is simply recommen-
dations. For questions or for components that

Care and cleaning

— Never clean the headlights or tail lights
with a dry cloth or sponge because the
lights could be damaged.
— Do not use any cleaning products that con-
tain alcohol, because they could cause
cracks to form.
— Wheels
— Never use any paint polish or other abra-
sive materials.
— Damage to the protective layer on the
rims, such as stone chips or scratches,
must be repaired immediately.
— Camera lenses
— Never use warm or hot water to remove
snow or ice from the camera lens. This
could cause the lens to crack.
— Never use abrasive cleaning materials or
alcohol to clean the camera lens. This
could cause scratches and cracks.
— Door windows
— Remove snow and ice on windows and ex-
terior mirrors with a plastic scraper. To re-
duce the risk of scratches, move the scra-
per only in one direction and not back and
forth.
— Never remove snow or ice from door win-
dows and mirrors using warm or hot water
because this could cause cracks to form.
—To reduce the risk of damage to the rear
window defogger, do not apply any stick-
ers on the heating wires on the inside of
the window.
— Decorative parts and trim
— Never use chrome care or cleaning prod-
ucts.
— Paint
—To reduce the risk of scratches, the vehicle
must be free of dirt and dust before pol-
ishing or waxing.
—To prevent paint damage, do not polish or
wax the vehicle in direct sunlight.
—To reduce the risk of paint damage, do not
polish away rust spots.
— Remove cosmetics and sunscreen immedi-
ately because they could damage the
paint.
— Decorative decals
—To reduce the risk of damage, do not use
any rough powder or abrasive cleaning
products.
—To reduce the risk of damage, do not pol-
ish decorative decals that have a matte or
printed finish.
— Due to the risk of damage, do not use an
ice scraper to remove snow and ice on win-
dows with decorative decals on them.
— Displays and instrument cluster
— Make sure that the display and instrument
cluster are switched off and have cooled
down before cleaning. To switch off the
center display, select on the MMI home
screen: SETTINGS > Display & brightness
> MMI > Screen cleaning.
— Displays, the instrument cluster, and the
trim surrounding it must not be cleaned
with dry cleaning methods because they
could become scratched.
— Make sure no fluids enter the spaces be-
tween the instrument cluster and the
trim, because that could cause damage.
— Controls
— Make sure that no fluids enter the con-
trols, because this could cause damage.
— Safety belts
— Do not remove the safety belts to clean
them.
— Never clean safety belts or their compo-
nents with chemicals or with corrosive flu-
ids or solvents and never allow sharp ob-
jects to come into contact with the safety
belts. This could cause damage to the belt
webbing.
— If there is damage to the webbing, the
connections, the retractors, or the buck-
les, have them replaced by an authorized
Audi dealer or authorized Audi Service Fa-
cility.
— Textiles, artificial leather, and Alcantara
— Never treat artificial leather or Alcantara
with leather care products, solvents, floor
polish, shoe polish, spot remover, or simi-
lar products.
— Have a cleaning specialist remove stub-
born stains to reduce the risk of damage.
