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


— 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.
@) 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.

ZA 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,
drive to an authorized Audi dealer or author-


ized Audi Service Facility immediately to
have the vehicle battery checked.
— Read the warnings when working in the en-
gine compartment > page 242.
— Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries.

@) Note
Jump start cables can cause considerable
damage to the vehicle electrical system if
they are connected incorrectly.
@ Tips
— There must be no contact between the
vehicles, or else voltage could flow when
connecting the positive terminal and drain
the vehicle battery of the vehicle providing
the jump start.
— The drained vehicle battery must be con-
nected correctly to the electrical system.
— Switch off electrical equipment that is not
needed.
