— A highly explosive mixture of gases can form
when charging batteries. Only charge the
battery in well-ventilated areas.
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). Do not charge or
use a frozen or thawed battery. If ice forms,
the battery housing can crack and battery
electrolyte can leak out, which increases the
risk of an explosion and chemical burns.

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, >
