Care and cleaning

— 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.
G) 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.

Emergency assistance

There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the spare tire from an-
other type of vehicle.
The compact spare tire is located in the luggage
compartment under the cargo floor cover
=> page 240.
The tire pressure must be 61 PSI (420 kPA).
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fails, mount the 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.

ZA WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
— Do not drive faster than 50 mph (80 km/h)
with a compact 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 compact spare tire.
— To reduce the risk of an accident, never drive
with more than one compact spare tire.
— Normal summer or winter tires must not be
mounted on the compact spare wheel rim.

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.

may cause the vehicle battery to explode
and lead to serious injuries.
—To reduce the risk of chemical burns, do not

bend over the vehicle battery.


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

() Note
Jump start cables can cause considerable
damage to the vehicle electrical system if
they are connected incorrectly.
G) 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.

cle.
Starting the engine
> Start the engine in the vehicle giving the charge
and let it run at idle.
> Now start the engine in your vehicle, which has
the
drained battery.
> If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approximately 30 seconds.
> Turn on the rear window defogger in your vehi-
cle in order to reduce any voltage peaks that
may occur when disconnecting the jump start
cables. The headlights must be switched off.
> With the engines running, remove the cables in
reverse order of the way they were installed.
> Close the cover on the positive terminal.

ZA WARNING
— Do not touch the non-insulated parts of the
terminal clamps. The cable must also not
come into contact with vehicle components
that conduct electricity when it is connected
to the positive vehicle battery terminal. This
can cause a short circuit.
— The plugs on the battery cells must not be
opened.
— Keep ignition sources (such as open flames,
burning cigarettes, etc.) away from the vehi-
cle batteries to reduce the risk of an explo-
sion.
— Route the jump start cables so they cannot
get caught in the moving parts in the other

vehicle's engine compartment.

q@ Note
— Do not use the negative terminal on the ve-
hicle battery for jump starting. A malfunc-
tion could occur in the vehicle electrical sys-
tem.
