Emergency assistance
Snow chains
Using snow chains on the collapsible spare tire is
not permitted for technical reasons.
If you need to drive with snow chains and your
vehicle has a flat tire, install the collapsible spare
tire on the axle where snow chains are not per-
mitted > page 277. Install the snow chains on
the tire that you removed, and install that in
place of the flat tire.
ZA 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.
@ 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 246.
— 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.
