2021 AUDI A6 heating

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.
— Laser scanner
— Never use abrasive cleaning materials to
clean the laser scanner. 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.
284
— 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
upper and lower 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 >

Care and cleaning

polish, shoe polish, spot remover, or simi-
lar products.
— Have a cleaning specialist remove stub-
born stains to reduce the risk of damage.
— Never use steam cleaners, brushes, hard
sponges, etc. when cleaning.
— Do not turn on the seat heating* to dry
the seat.
— Objects with sharp edges, such as zippers
or rivets on clothing or belts, can cause
damage to the surface.
— Open hook and loop fasteners, for exam-
ple on clothing, can damage seat covers.
Make sure hook and loop fasteners are
closed.
— Natural leather
— Never treat leather with solvents, floor
polish, shoe polish, spot remover or simi-
lar products.
— Objects with sharp edges, such as zippers
or rivets on clothing or belts, can cause
damage to the surface.
— Never use steam cleaners, brushes, hard
sponges, etc. when cleaning.
— Do not turn on the seat heating* to dry
the seat.
—To help prevent the leather from fading,
do not leave the vehicle in direct sunlight
for long periods of time. If leaving the ve-
hicle parked for long periods of time, you
should cover the leather to protect it from
direct sunlight.
@ Tips
— Insects are easier to remove from paint that
has been freshly waxed.
— Regular waxing can prevent rust spots from
forming.
— Decorative decals can age due to environ-
mental conditions, which can result in dam-
age such as brittleness. The color may fade
if exposed to excessive sunlight.
Taking your vehicle out
of service
If you would like to take your vehicle out of serv-
ice for a long period of time, contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty. You can receive information about the meas-
ures to take depending on the conditions for tak-
ing the vehicle out of service (duration, location,
etc.).

Emergency assistance

> Connect the compressor hose to a vehicle sock-
et and switch it on.
> Let the compressor run until the specified value
on the tire pressure sticker is reached
> page 266, fig. 169>@.
> Screw the valve cap back onto the valve.
Returning to storage
> To release air, turn the valve insert. See an au-
thorized Audi dealer or authorized Audi Service
Facility.
> Turn the valve insert back once the air has been
released.
> Wait several hours before placing the collapsi-
ble spare tire in the spare wheel well. Only then
will it fold down completely so that you can
store it securely.
> Then screw the valve cap back onto the valve.
> Secure the collapsible spare tire with the hand-
wheel.
> Fold the cargo floor cover back into place.
Snow chains
Using snow chains on the collapsible spare tire is
not permitted for technical reasons.
If you have to drive with snow chains and a front
tire fails, mount the collapsible spare tire in place
of a rear tire. Install the snow chains on the rear
tire that you removed, and install that in place of
the front tire that failed.

Z\ WARNING
— Only use the collapsible spare tire in emer-
gencies and drive very carefully, especially if
it is more than six years old.
— The compressor and the hose can become
very hot during operation which increases
the risk of burn injuries.
— After installing a collapsible spare tire, the
tire pressure must be checked as quickly as
possible to reduce the risk of an accident.
— Do not drive faster than 50 mph (80 km/h)
with the collapsible spare tire. Driving faster
than that increases the risk of an accident.
— To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the collapsible spare

tire.

— Never drive using more than one collapsible
spare tire, because this increases the risk of
an accident.
— Normal tires or winter tires must not be
mounted on the collapsible spare tire rim.
C) Note
The compressor must be switched off after six
minutes at the most to reduce the risk of
overheating. Let the compressor cool down
for several minutes before using it again.


Jump starting
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
If the engine does not start because the vehicle
battery is drained, you can jump start your vehi-
cle using another vehicle. Jump start cables are
needed to do this.
Both vehicle batteries must have 12 V nominal
voltage. The voltage capacity (Ah) of the vehicle
battery that is giving power must not be less
than the capacity of the drained vehicle battery.
Jump start cable
Only use a jump start cable with a large enough
diameter. Note the manufacturer's specifica-
tions.
Only use a jump start cable with insulated termi-
nal clamps.
Positive cable - usually red.
Negative cable - usually black.

Z\ WARNING
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). If the vehicle bat-
tery is frozen, it must be thawed before con-
necting the jump start cables. If it is not,
the risk of an explosion and chemical burns
increases. After jump starting the vehicle, >

Fuses and bulbs


This can cause damage to the electrical sys-

checked as soon as possible by an authorized
Audi dealer or authorized Audi Service Facili-
ty.
